A study of some biochemical and histopathological responses of wet-stored recalcitrant seeds of Avicennia marina infected by Fusarium moniliforme. (1/46)

Although fungi cause a recognized problem during storage of recalcitrant seeds of many tropical species, there are no data to date on defence strategies of these seeds against fungal attack. To ascertain whether recalcitrant seeds of Avicennia marina elaborate compounds that might suppress fungal proliferation during hydrated storage, the production and efficacy of beta-1,3-glucanase (EC 3.2.1.39) and chitinase (EC 3.2.1.14) were studied in relation to histopathological changes. Freshly harvested seeds had low beta-1,3-glucanase and chitinase activities and fluorescence microscopy revealed progressive deterioration of the internal tissues of these seeds associated with fungal infection during hydrated storage. In seeds treated to minimize associated fungi (clean seeds), beta-1,3-glucanase and chitinase activities increased significantly during 10 d of hydrated storage. Similar high levels of activity were observed when these seeds were experimentally infected with Fusarium moniliforme and subjected to further storage. The histopathological observations indicated delayed disease development in the 10-d clean-storage period, although the hypersensitive response was not observed. The results suggest that, although the recalcitrant seeds of A. marina elaborate some antifungal enzymes, there is a lack of effective defence strategies that might lead to successful responses against fungal infections.  (+info)

Genetic variation of Avicennia marina (Forsk.) Vierh. (Avicenniaceae) in Vietnam revealed by microsatellite and AFLP markers. (2/46)

Genetic variation of Avicennia marina in the costal area of Vietnam was examined using microsatellite and AFLP markers. By using five microsatellite loci a total of 21 alleles were detected. The average number of alleles per locus per population ranged from 1.667 to 3.000. The observed heterozygosity varied from 0.180 to 0.263, with an average of 0.210 indicating relatively low level of genetic variation comparing to the previous studies on A. marina in the worldwide range. The expected heterozygosity was larger than the observed heterozygosity leading to positive inbreeding coefficients in all the six populations. Highly significant departures from Hardy-Weinberg Equilibrium were detected in four populations. AFLP analysis revealed a total of 386 loci, of which 232 (60.1%) were polymorphic. In congruent with microsatellite markers relatively low levels of genetic variation were detected at both gene and nucleotide levels (H = 0.086; pi = 0.0054). Reduced level of genetic variation was found in the central population, and in the southern populations. Both microsatellite and AFLP markers revealed large genetic differentiation (F(ST) = 0.262 and 0.338, respectively) indicating strong genetic structure among regional populations. Pairwise genetic distance by AFLP showed two populations in the north and the other two in the south are closely related each other.  (+info)

Correlation between anammox activity and microscale distribution of nitrite in a subtropical mangrove sediment. (3/46)

The distribution of anaerobic ammonium oxidation (anammox) in nature has been addressed by only a few environmental studies, and our understanding of how anammox bacteria compete for substrates in natural environments is therefore limited. In this study, we measure the potential anammox rates in sediment from four locations in a subtropical tidal river system. Porewater profiles of NO(x)(-) (NO2- plus NO3-) and NO2- were measured with microscale biosensors, and the availability of NO2- was compared with the potential for anammox activity. The potential rate of anammox increased with increasing distance from the mouth of the river and correlated strongly with the production of nitrite in the sediment and with the average concentration or total pool of nitrite in the suboxic sediment layer. Nitrite accumulated both from nitrification and from NO(x)(-) reduction, though NO(x)(-) reduction was shown to have the greatest impact on the availability of nitrite in the suboxic sediment layer. This finding suggests that denitrification, though using NO2- as a substrate, also provides a substrate for the anammox process, which has been suggested in previous studies where microscale NO2- profiles were not measured.  (+info)

Global voices of science: Mangroves, fishponds, and the quest for sustainability. (4/46)

Aquaculture, the farming of shrimp and other useful aquatic and marine plants and animals in artificially confined and tended ponds, pens, and cages, ranks as a phenomenal success story in global food production. In 1975, aquaculture contributed 8% to the overall yield of the world's fish harvest; now it provides more than one-third of the yield. Total aquaculture production in 2003 was 54.8 million metric tons valued at 67.3 billion in U.S. dollars. More than 90% of this output comes from Asia, where aquaculture has its origins and where this month's essay author has lived and worked all of her life. In her essay, Jurgenne H. Primavera, senior scientist of the Aquaculture Department of the Southeast Asian Fisheries Development Center based in Iloilo, Central Philippines, traces the recent history of aquaculture and the socioeconomic and environmental challenges that its rapid growth has wrought, especially for the mangrove ecosystems in which much of brackishwater pond aquaculture occurs. With an eye on all stakeholders, Primavera lays out how aquaculture is now falling short of the goal of sustainability and what steps might be taken to move the industry in that direction.  (+info)

Factors contributing to dwarfing in the mangrove Avicennia marina. (5/46)

BACKGROUND AND AIMS: In Richards Bay, South Africa, Avicennia marina frequently exhibits a distinct productivity gradient, with tree height decreasing markedly from 6-10 m in the fringe zone to <1.5 m in the dwarf zone which is 120 m inland at a slightly higher elevation. In this investigation, soil physico-chemical conditions between fringe and dwarf A. marina were compared and the constraints imposed by any differences on mangrove ecophysiology and productivity determined. METHODS: Soil and plant samples were analysed for inorganic ions using spectrophotometry. Gas exchange measurements were taken with an infrared gas analyser and chlorophyll fluorescence with a fluorometer. Xylem psi was determined with a pressure chamber and chlorophyll content with a chlorophyll absorbance meter. RESULTS: In the dwarf site, soil salinity, total cations, electrical conductivity and soil concentrations of Na(+), K(+), Ca(2+), Mg(2+), Zn(2+), Mn(2+) and Cu(2+) were significantly higher than those in the fringe zone. Soil water potential and the concentration of soil P, however, were significantly lower in the dwarf site. In the leaves, Na(+) was the predominant ion and its concentration was 24 % higher in dwarf than fringe mangroves. Leaf concentrations of K(+), Ca(2+), Mg(2+), Mn(2+) and P, however, were significantly lower in dwarf mangroves. Photosynthetic performance, measured by gas exchange and chlorophyll fluorescence, was significantly reduced in the dwarf plants. CONCLUSIONS: The results suggest that hydro-edaphic factors contribute to high soil salinities, low water potentials, water stress and ion imbalance within tissues including P deficiency, which in interaction, contribute to dwarfing in Avicennia marina.  (+info)

Analysing ethnobotanical and fishery-related importance of mangroves of the East-Godavari Delta (Andhra Pradesh, India) for conservation and management purposes. (6/46)

Mangrove forests, though essentially common and wide-spread, are highly threatened. Local societies along with their knowledge about the mangrove also are endangered, while they are still underrepresented as scientific research topics. With the present study we document local utilization patterns, and perception of ecosystem change. We illustrate how information generated by ethnobiological research can be used to strengthen the management of the ecosystem. This study was conducted in the Godavari mangrove forest located in the East-Godavari District of the state Andhra Pradesh in India, where mangroves have been degrading due to over-exploitation, extensive development of aquaculture, and pollution from rural and urbanized areas (Kakinada).One hundred interviews were carried out among the fisherfolk population present in two mangrove zones in the study area, a wildlife sanctuary with strong conservation status and an adjacent zone. Results from the interviews indicated that Avicennia marina (Forsk.) Vierh., a dominant species in the Godavari mangroves, is used most frequently as firewood and for construction. Multiple products of the mangrove included the bark of Ceriops decandra (Griff.) Ding Hou to dye the fishing nets and improve their durability, the bark of Aegiceras corniculatum (L.) Blanco to poison and catch fish, and the leaves of Avicennia spp. and Excoecaria agallocha L. as fodder for cattle. No medicinal uses of true mangrove species were reported, but there were a few traditional uses for mangrove associates. Utilization patterns varied in the two zones that we investigated, most likely due to differences in their ecology and legal status. The findings are discussed in relation with the demographic and socio-economic traits of the fisherfolk communities of the Godavari mangroves and indicate a clear dependency of their livelihood on the mangrove forest.Reported changes in the Godavari mangrove cover also differed in the two zones, with significantly less perceptions of a decrease in the protected area, as compared to the adjacent non-protected area. A posteriori comparisons between sequential satellite imagery (retrospective till 1977) and respondents that were at least 15 years back then, revealed a mangrove decrease which was however perceived to different extents depending on the area with which the fishermen were familiar. While local needs had not been incorporated in the existing policy, we created a framework on how data on ethnobotanical traditions, fishery-related activities and local people's perceptions of change can be incorporated into management strategies.  (+info)

Paleoenvironment interpretation of a 1760 years B.P. old sediment in a mangrove area of the Bay of Guanabara, using pollen analysis. (7/46)

A sediment sample was obtained at 122 cm from the top of a drilling core in the Guapimirim mangrove, Bay of Guanabara, and analyzed using pollen analysis. This muddy core reached a sandy ground at 133 cm. 14C datation got the age of 1760 +/- 50 years B.P. The most frequent pollen grains were mangrove species of Rhizophora mangle, Laguncularia racemosa and Avicennia schaueriana. "Restinga" and tropical rain forest vegetation was recognized behind the mangrove. After the last sea transgression at 2500 years B.P., the water level lowered to its actual size, allowing the installation of this mangrove.  (+info)

Purification and partial characterization of an acidic polysaccharide with complement fixing ability from the stems of Avicennia marina. (8/46)

An acidic polysaccharide fraction that had high anticomplementary activity was isolated from the stems of Grey Mangrove in 0.15% yield. The final fractions was designated HAM-3-IIb-II. The polysaccharide fraction appeared to be homogenous by high performance size exclusion chromatography with an estimated molecular weight of 105 kDa. The isolated polysaccharide is more effective than polysaccharide K (PSK) in its anticomplementary activity at 58 microg/ml of PSK and 23 microg/ml of HAM-3-IIb-II that inhibit 50% of complement activity in the complement fixation assay. Structural studies indicated that HAM-3-IIb-II was rich in galacturonic acid along with arabinose, galactose and rhamnose, characterizing a pectin-type polysaccharide, which was also confirmed by FT-IR spectrum. The presence of rich neutral sugar side chains of arabinogalactans may have contributed to the expression of high activity. Traditionally, this mangrove plant is used for medicinal purposes and it appears to have some scientific applications.  (+info)

In February 2017, three plots were established, each at a distance of 0 m (D0), 50 m (D50), and 100 m (D100) from the inland boundary of a mangrove forest. Soil samples were collected at 0-10-cm depth in each plot to determine the chemical properties, and the ...
In flooded and non-flooded impounded forests of Black mangrove (Avicennia germinans), the community structure of the ammonia-oxidizing betaproteobacteria (β-AOB) differed among distinct mangrove vegetation cover types and hydrological regimes. This had been explained by a differential response of lineages of β-AOB to the prevailing soil conditions that included increased levels of moisture and ammonium. To test this hypothesis, slurries of soils collected from a flooded and a non-flooded impoundment were subjected to enhanced levels of ammonium in the absence and presence of additional shaking. After a period of 6 days, the community composition of the β-AOB based on the 16S rRNA gene was determined and compared with the original community structures. Regardless of the incubation conditions and the origin of the samples, sequences belonging to the Nitrosomonas aestuarii lineage became increasingly dominant, whereas the number of sequences of the lineages of Nitrosospira (i.e., Cluster 1) and
Salinity Induced Changes in the Leaf Anatomy of the Mangrove Avicennia marina along the Anthropogenically Stressed Tropical Creek Abstract.
The broad goals of this dissertation were to better understand global mangrove expansion at the cost of salt marsh habitat through literature review and to better understand Avicennia germinans phylogeography in the northern Gulf of Mexico by use of a modern next generation sequencing technique known as double digest RAD-sequencing. From the literature review, human activities both past and present were found to have significantly altered both salt marsh and mangrove habitat. Currently salt marsh habitat across the world is experiencing large habitat loss and fragmentation, while mangrove populations are expanding both poleward and landward. The current loss and fragmentation of salt marsh habitat along with the superiority of the mangrove species dispersal capability suggests that salt marshes across the globe are ripe for mangrove species encroachment and conversion. For mangrove phylogeography in the northern Gulf of Mexico, the genetic structure and the kinship of Avicennia germinans ...
Traditionally, mangrove plants have been used medicinally in diverse cases like to treat infections, relief pain and purify blood and as antioxidant. Avicennia officinalis is a folk medicinal plant used mainly against rheumatism, paralysis, asthma, snake-bites, skin disease, hepatitis, leprosy and ulcer. Phytochemical constituents from Avicennia officinalis leaf extracts were determined qualitatively. Crude extracts of the plants under study were screened for the presence of alkaloids, phenolics, flavonoids, tannins, diterpenes, triterpenes, sterols, saponins, glycosides, proteins, carbohydrates and reducing sugars.

Avicennia marina (AM) exhibits various biological activities and has been traditionally used in Egypt to cure skin diseases. In this study, the methanolic heartwood extract of AM was evaluated for inhibitory activity against 5α-reductase (5α-R) [E.C.1.3.99.5], the enzyme responsible for the over-production of 5α-dihydrotestosterone (5α-DHT) causing androgenic alopecia (AGA). An AGA-relevant cell-based assay was developed using human hair dermal papilla cells (HHDPCs), the main regulator of hair growth and the only cells within the hair follicle that are the direct site of 5α-DHT action, combined with a non-radioactive thin layer chromatography (TLC) detection technique. The results revealed that AM is a potent 5α-R type 1 (5α-R1) inhibitor, reducing the 5α-DHT production by 52% at the final concentration of 10 µg/mL. Activity-guided fractionation has led to the identification of avicequinone C, a furanonaphthaquinone, as a 5α-R1 inhibitor with an IC50 of 9.94 ± 0.33 µg/mL or 38.8 ± 1.29
Aquaporins and ABC transporters were the major transporters identified in our study. ABC transporters are known to transport fatty acids that are required for proper cuticle development in leaves [45]. The cuticle plays an important role in maintaining the structural integrity of salt glands. Under saline conditions, it becomes important for the salt glands to form a thick cuticular layer to prevent water loss and also diffusion of ions into neighbouring cells [6]. The observed high level of expression of ABC transporters in the salt gland-rich tissue could explain this in Avicennia salt gland cells. Aquaporins are known to regulate water movement across the membranes. During drought and salt exposure, aquaporins are known to maintain water balance in the cells [46] and have been shown to play a crucial role in salt secretion of A. officinalis [9]. Although aquaporins have been identified from the leaves of other salt secretors [41], its precise function in regulating water movement during ...
Species zonation patterns across tidal gradients in mangrove forests are formed by successful seedling establishment and maintained by replacement of adults by conspecific seedlings. These two processes rarely have been examined experimentally in neotropical mangal. We studied survivorship and growth of seedlings of two species of mangrove, Rhizophora mangle L. and Avicennia germinans (L.) Stearn, across a tidal gradient in Belize, Central America. Propagules of each species were planted in common gardens at tidal elevations corresponding to lowest low water (LLW), mean water (MW), and highest high water (HHW). Sixty-nine percent of Rhizophora seedlings planted at MW and 56% of those planted at LLW survived 1 year. Forty-seven percent of MW Avicennia seedlings also survived 1 year. No individuals of either species survived at HHW, and neither did any LLW Avicennia seedlings. Among the surviving Rhizophora seedlings, LLW seedlings grew more rapidly in terms of height, diameter, leaf production, ...
TY - JOUR. T1 - Differences in morphology, carbon isotope ratios, and photosynthesis between scrub and fringe mangroves in Florida, USA. AU - Lin, Guanghui. AU - Sternberg, Leonel. PY - 1992/1/1. Y1 - 1992/1/1. N2 - All three mangrove species in Florida (USA), Rhizophora mangle L., Laguncularia racemosa Gaert. and Avicennia germinans (L.) L., are found frequently in scrub mangrove forests, in which individuals rarely exceed 1.5 m in height. In the present study, the differences in morphological characteristics, leaf carbon isotope ratios and photosynthetic gas exchange between individuals in scrub and fringe mangrove forests in south Florida were investigated quantitatively. Plants in the scrub forests had much lower canopy height, more main stems per tree and smaller leaves, relative to those in the fringe forests. There was a significant correlation between tree height and leaf δ13C value, with higher δ13C values (1-4% more positive) for plants in the scrub mangrove forests. Correspondingly, ...
Among blue carbon ecosystems, mangroves are very efficient in storing carbon in their sediments over decadal to millennial time scales. However, this ability varies with numerous parameters, including climate and sea-level variations. In New Caledonia, mangrove ecosystems develop in semi-arid conditions with a typical zonation: Rhizophora spp. colonize the seaward side of the intertidal area, while Avicennia marina develops at higher elevations, just below the salt-flat. Within this context, we determined both the quantity (organic carbon content and carbon stocks) and the characteristics (carbon over nitrogen ratios (C/N), stable carbon and nitrogen isotopes, radiocarbon age) of the organic matter stored beneath each mangrove stands. Carbon stocks were determined down to different limits with depth: approximate extension of the root systems, one-meter depth, and the hard substrate. Within the extension of the root systems, the sediment carbon stock was lower than 100 MgC ha−1 regardless of the
Endophytic actinobacteria are one of the important pharmaceutical resources and well known for producing different types of bioactive substances. Nevertheless, detection of the novelty, diversity, and bioactivity on endophytic actinobacteria isolated from mangrove plants are scarce. In this study, five different mangrove plants, Avicennia marina, Aegiceras corniculatum, Kandelia obovota, Bruguiera gymnorrhiza, and Thespesia populnea, were collected from Beilun Estuary National Nature Reserve in Guangxi Zhuang Autonomous Region, China. A total of 101 endophytic actinobacteria strains were recovered by culture-based approaches. They distributed in 7 orders, 15 families, and 28 genera including Streptomyces, Curtobacterium, Mycobacterium, Micrococcus, Brevibacterium, Kocuria, Nocardioides, Kineococcus, Kytococcus, Marmoricola, Microbacterium, Micromonospora, Actinoplanes, Agrococcus, Amnibacterium, Brachybacterium, Citricoccus, Dermacoccus, Glutamicibacter, Gordonia, Isoptericola, Janibacter, Leucobacter,
Zonation often characterizes mangrove forests. Certain species occupy particular areas, or niches, within the ecosystem. Some mangrove species occur close to shores, fringing islands, and sheltered bays; others are found further inland, in estuaries influenced by tidal action.. Mangroves vary in height according to species and environment, from mere shrubs to 40 meter (app. 131 feet) tall trees. The prop roots of some mangrove species, such as Rhizophora spp., or red mangrove, and the pneumataphores (unique breathing roots) of others, such as Avicennia spp., or black mangrove, contain many small breathing pores, called lenticels. These allow oxygen to diffuse into the plant and down to the underground roots by means of air space tissue in the cortex, called aerenchyma. The lenticels are inactive during high tide.. Lenticels in the exposed portions of mangrove roots are highly susceptible to clogging by crude oil and other pollutants, attacks by parasites, and prolonged flooding from ...
The characteristics of macrofauna communities in three mangrove assemblages[Avicennia marina+Acgiceras corniculatum (MC)community, A. corniculatum (C) community and Bruguiera gymnorrhiza+A. corniculatum (GC) community]were studied in Zhanjiang Mangrove Nature Reserves during 2005 and 2006. Of the three mangrove assemblages, the macrofauna species number, density, biomass, Richness index and Shannon-Wiener index were the highest, and the Simpson dominance index was medial at MC community. However the Pielou Evenness index of MC community was slightly lower than that at C community. At C community, the number of macrofauna species obviously reduced, especially infaunal, caving and adhering life forms, and the biomass and density were the lowest. Because of the even distribution of individuals of different species, the Simpson dominance index was the lowest and the evenness index was the highest. Although the Richness index at C community was slightly lower than that at MC community, the ...

The use of spectral response curves for estimating nitrogen (N) leaf concentrations generally has been found to be a challenging task for a variety of plant species. In this investigation, leaf N concentration and corresponding laboratory hyperspectral data were examined for two species of mangrove (Avicennia germinans, Rhizophora mangle) representing a variety of conditions (healthy, poor condition, dwarf) of a degraded mangrove forest located in the Mexican Pacific. This is the first time leaf nitrogen content has been examined using close range hyperspectral remote sensing of a degraded mangrove forest. Simple comparisons between individual wavebands and N concentrations were examined, as well as two models employed to predict N concentrations based on multiple wavebands. For one model, an Artificial Neural Network (ANN) was developed based on known N absorption bands. For comparative purposes, a second model, based on the well-known Stepwise Multiple Linear Regression (SMLR) approach, was employed
ABSTRACT: Physical processes limiting colonization of bare tidal flats by pioneer mangrove species have commonly been described but not yet quantified. Understanding thresholds to early seedling establishment is critical for successful restoration and management of mangrove forests. We determined how seedling establishment of Avicennia alba Bl. is affected by the combination of increasing hydrodynamic forces and sediment dynamics. As the buoyant propagules of A. alba are dispersed by water, early establishment on bare tidal flats requires propagules to quickly anchor to stay in place. Flume studies and field observations showed that 3 thresholds have to be passed until the seedling is successfully established: (1) stranded propagules need an inundation-free period to rapidly develop roots that are long enough to withstand displacement by flooding, (2) roots need to become long enough to withstand seedling dislodgement by hydrodynamic forces from waves and currents, with the required root length ...

The study attempts to image the mobility of saline porewater beneath a black mangrove forest on a siliciclastic barrier island off the Atlantic coast of Florida. The forest is broken up into a series of impoundments bounded by earthen dikes, which prevent surface water exchange between both neighboring impoundments and a brackish, tidal intracoastal lagoon. Water management practices pump lagoon water into impoundments for six months (wet season) and leave them to dry up for another six (dry season). Our study was conducted during the end of a dry season. The movement or storage of pumped salts is unknown. Our objective is to capture that movement-- in the absence of surface interaction between impoundments and the lagoon-- over a diurnal cycle with time-lapse electric resistivity. The resistivity transect crosses over a saltpan with little to no vegetation and extended into black mangrove trees at either end. Throughout the diurnal period, a relatively conductive zone persists from a ...
Background: A large-scale systematical investigation of the influence of Pleistocene climate oscillation on mangrove population dynamics could enrich our knowledge about the evolutionary history during times of historical climate change, which in turn may provide important information for their conservation.. Results:In this study, phylogeography of a mangrove tree Sonneratia alba was studied by sequencing three chloroplast fragments and seven nuclear genes. A low level of genetic diversity at the population level was detected across its range, especially at the range margins, which was mainly attributed to the steep sea-level drop and associated climate fluctuations during the Pleistocene glacial periods. Extremely small effective population size (Ne) was inferred in populations from both eastern and western Malay Peninsula (44 and 396, respectively), mirroring the fragility of mangrove plants and their paucity of robustness against future climate perturbations and human activity. Two major ...

The numerical model described in this work has been designed to study the flow of carbon and nitrogen in a mangrove forest at Gazi Bay, Kenya. Several processes and storages of matter considered vital in the functioning of the ecosystem have been reviewed to help in the abstraction of the model and analysis. A numerical model represents the functioning of the ecosystem but is always limited due to the complexity of the system and lack of information on processes. A review of modelling work concerned with coastal ecosystems reveals that modelling is not only a means of summarising data from field studies, but that it can also be an integrated part of research effort useful in formulating research hypotheses and drawing up management options. The objectives of the Gazi model are similar in this respect. The abstraction of the system is presented as a box and arrow diagram showing storages and flows of matter. Changes in each of the state variables are function of some input and output processes ...

Part of the problem now is that a lot of the data we need to make this type of assessment simply isnt available, said Sally Hacker, an OSU associate professor of zoology. Biological, economic and sociological data could be enormously helpful to help us reach better management decisions, and this is something we need to improve.. Fairly good data were available in the case of the Thailand mangrove forests, however, and researchers used it to make their case. On a given area of mangrove forest there, the assigned value of ecosystem services - storm protection, biological habitat, etc. - was determined to be about $19 million with a hands-off approach and no commercial use whatsoever.. But with a full range of uses, which included leaving 80 percent of the area in mangrove forests and gaining almost all of their flood protection ability, the value was found to be $17.5 million, Hacker said.

Permeability and crusting hazards are evaluated by electrical conductivity (ECiw,) and the sodium adsorption ratio predicted to occur in the topsoil after irrigation (SARsw) with reference to threshold tolerances (permissible combinations of ECiw and SARsw) established for the specific soil in question or, in the absence of specific information, an appropriate general relation. SARsw is predicted using a computer model (such as Watsuit, which is used in this publication) or, in the absence of a computer, using the SAR value of the irrigation water (SARiw). Salinity, toxicity and nutritional problems are evaluated by comparing levels of soil water salinity, concentrations of toxic ions and ratios of Ca/Mg predicted (with Watsuit) to result in the rootzone of the soil after irrigation with reference to acceptable values of salinity, toxic-ion concentrations and Ca/Mg ratios for the specific crop (s) in question. Tables of acceptable levels of salt and toxic-ion concentrations are provided for many ...
Automated in situ instrumentation captured high-resolution surface water pCO2, CH4 and222Rn data at the creek mouth, and ∼500 m upstream in a sub-tropical mangrove ecosystem (Southern Moreton Bay, Australia, S27.78°, E153.38°) over a spring-neap-spring tidal cycle (∼15 days) during November 2013. The partial pressure of CO2 (pCO2) ranged from 385 to 26,106 μatm, CH4 from 1.8 to 889 nM, and 222Rn from 280 to 108,172 dpm m−3. Average surface water pCO2, CH4 and 222Rn were 4-fold higher at the upstream station. Surface water fluxes of CO2 and CH4 ranged from 9.4 to 629.2 mmol CO2 m−2 d−1 and 13.1 to 632.9 μmol CH4 m−2 d−1 depending upon the gas transfer model used and station location. Creek pCO2, CH4 and 222Rn displayed changes over both semi-diurnal and spring-neap-spring tidal scales. Semi-diurnally, all gases had a significant inverse relationship with water depth. Over the spring-neap-spring cycle, all gases exhibited an inverse relationship with tidal amplitude, with higher ...

Biodiversity delivers a variety of crucial services. These can be categorised as follows:. • Provisioning services deliver products that are essential to our daily life such as food, drugs, building materials, fibers, etc. … Just think about the fruit, vegetables or meat we eat, the substances we extract from plants or animals to battle diseases, the wood we use in construction, …. • Regulating services are those that support the functioning of our environment, such as climate regulation through enhanced evaporation or carbon dioxide uptake and fixation, the purification of water, breakdown of pollutants, or even protection against calamities: during the Indonesian tsunami of 2004, coastal zones with mangrove forests were less severely affected than zones that were deforested for constructing hotels …. • Cultural services are those non-tangible benefits that enrich our society: recreation, tourism, art, science and culture, spiritual well-being… animals and plants play an important ...

Inside a mangrove forest. Enter a mangrove forest. In this dark water world, trees with twisted limbs live double lives-one foot on land, the other in the sea.. Some 80 species of mangroves, also called mangals, thrive in salty coastal habitats in the tropics and subtropics. All take root in waterlogged soils where slow-moving currents allow sediment to accumulate. Red, black and white mangrove trees, along with buttonwoods, may grow along the same shoreline. Where these species are found together, each stakes out a spot.. Red mangroves are closest to the seas edge; their prop roots extend into the water from branches above. The roots capture sediment, stabilizing the shore. Farther inland are black mangroves with oxygen-supplying pneumatophores pointing upward from the soil. White mangroves, with no special root adaptations, are found in interior mangrove forests, followed by buttonwoods in upland transition zones.. These forests-of-the-tide collectively cover a worldwide area of about 20,535 ...
Mangrove forest soil is a habitat and source of diversity of microorganisms, including thermophilic bacteria. The utilization of thermophilic bacteria has been carried out in the pharmaceutical field, especially as a source of raw materials for pharmaceutical products. This study aims to provide an overview of the population of thermophilic bacteria found in mangrove forest soils. Soil samples were obtained by random stratification with a depth of 5-10 cm at 9 points from 3 strata. The isolation media used were Starch Casein Agar (SCA), and the groups of bacteria determined by using the Gram staining method. The selected thermophilic bacteria from mangrove forest soil totaling 64 isolates consisted of Gram-negative that divides into 20 bacilli, 9 cocci, 6 vibrios, and Gram-positive consisted of 26 bacilli, 3 cocci. The highest population of thermophilic bacteria from mangrove forest soils was Gram-negative as many as 35 isolates.. ...
Mangroves are various types of trees up to medium height and shrubs that grow in saline coastal sediment habitats in the tropics and subtropics The remaining mangrove forest areas of the world in 2000 was 137,760 km_. The mangrove biome is a distinct saline woodland or shrubland habitat characterized by depositional coastal environments, where fine sediments (often with high organic content) collect in areas protected from high-energy wave action. Mangroves dominate three-quarters of tropical coastlines. The saline conditions tolerated by various mangrove species range from brackish water, through pure seawater, to water concentrated by evaporation to over twice the salinity of ocean seaw...

Seasonal patterns of leaf recruitment (Figure 6A) in R. stylosa are highly correlated (r = 0.88, p , 0.01) with those of stipule litterfall (Figure 6B), while seasonal patterns of leaf death (Figure 6A) in this species also correlated (r = 0.82, p , 0.01) well with those of leaf litterfall (Figure 6B). In R. stylosa leaves that flushed in summer represented 38.1% of the annual total, whereas only 15.8% flushed in winter (Figure 6A). A similar seasonal trend in leaf recruitment in K. obovata was recorded (Gwada et al. [2000]; Analuddin et al. [2009]; Kamruzzaman et al. [2012a]). Hardiwinoto et al. ([1989]) and Kamruzzaman et al. ([2012c]) also reported a similar seasonal trend in B. gymnorhiza, with the highest values in summer and the lowest in winter. Leaf recruitment and stipule litterfall of R. stylosa, B. gymnorhiza and K. obovata species on Okinawa are strongly correlated with the mean monthly air temperature and hours of sunshine (Sharma et al. [2012b]). These results are also supported by ...
The saltwater mosquito, Aedes vigilax, is prolific in coastal wetlands including mangroves and saltmarshes. Ae. vigilax is a vector for arboviruses such as Ross River and Barmah Forest viruses, with significant consequences for human health and economic productivity. In Australia the dominant form of mosquito control is chemicals. For mangroves, this is because there is a critical lack of knowledge supporting alternative approaches, such as environmental modification or biological control using larvivorous fish. This review examines the potential of fish as biological agents for the control of mosquito larvae in mangroves. We consider two key aspects: how larvivorous fish use mangroves; and can larvivorous fish reduce larval mosquito populations sufficiently to provide effective mosquito control? The link between fish and mangroves is reasonably well established, where mangroves act as refuge habitat for small and juvenile fish. Also, research has established that fish can be significant ...
Various mangrove saplings have been planted in above 2,700 hectares of area to improve the mangrove forest cover in Krishna district since 2007, said Ms. Subhadra Devi. The mangrove serves as breeding and nursing grounds for marine and pelagic species.

Now I read that the Rice Terraces are used to introduce schoolchildren to engineering concepts. The Pew modules likewise use mangroves as an entry point to introduce students to continental drift, earthquakes, tsunamis, storm surges, greenbelts and other scientific concepts/phenomena. No need for DepEd to invest time and money in development, only in reproducing and mainstreaming the modules in coastal primary schools throughout the country. So perhaps someone in this egroup can show Sec. Luistro that the mangrove modules in fact are rich in lessons that can ground a child to his native ecology, specifically, the mangrove ecosystem (and also coral reefs and seagrasses) which is as tropical as you can get. BTW, some half dozen copies have been submitted to various DepEd officials. For any help in increasing mangrove awareness, thank you. ...

Community-Based Ecological Mangrove Restoration (CBEMR) is a holistic, multi-stage approach, that includes local stakeholders and other groups from the outset. These might include local or international NGOs, Environment or Forest Department staff, local government units and other relevant and interested groups. The MAP team engages in extensive discussions before the training to ensure the workshop is tailored to the needs of participants involved and the local mangrove conditions. Pertinent areas of mangrove ecology, biology and social science are included to combat specific challenges such as very high salinity, or over-harvesting of mangrove wood.. CBEMR starts with a detailed investigation of the proposed site to understand the reasons for previous mangrove losses and why mangroves are not naturally regenerating. Mangrove teams need to understand the biophysical parameters of the site, the ecology of the species present or expected, local hydrology and topography, and other features that ...
Feeding. The Red-headed Myzomela is arboreal, feeding at flowers and among the outer foliage in the crowns of mangroves and other flowering trees. It is very active when feeding, darting from flower to flower and sallying for insects. It probes flowers for nectar with its long curved bill, catches insects on the wing and gleans insects from leaves. It predominately feeds on mangrove species, and in northwestern Australia is the major pollinator of Bruguiera exaristata, however it also feeds in paperbarks and other coastal forests and has been recorded feeding in cultivated Bottlebrush and Grevillea in Darwin gardens. ...
Mangrove vegetation, which grows naturally in subtropical shorelines, provides a wide range of ecosystem functions such as reducing coastal erosion, promoting biodiversity, and removing nitrogen, phosphorus and carbon dioxide. These vital ecological functions are influenced by the water flow around the intricate mangrove roots, which create a complex energetic process that mixes up sediments and generates a depositional region behind the roots. How these mangrove roots interact with water flow is believed to be a key element in mitigating coastal erosion. Accurately projecting hydrodynamic erosion and the essential amount of mangrove species has been a challenge for managers and restoration experts to forecast a successful component of project designs. That is because they need two critical pieces of information: characterization of the near-bed boundary layer of the mangrove roots and their effect on the mangrove root erosion; and a quantitative understanding of mangrove root erosion and the ...
Due to increasing human population and rapid economic development, mangrove communities are experiencing a significant decline globally. The decline of mangrove communities leads to the shortening of shorelines, which has decreased from 198 km in 1980 to 158 km in 1990, with only 147 km remaining in 2003 (Food and Agricultural Organization FAO 2003). During the past several decades, the extent of mangroves along the South China coast sharply decreased as a result of land reclamation in the 1970s and aquaculture in the early 1980s; the area of mangroves dropped from 400,000-420,000 ha in 1956 to 21,283 ha in 1986 and then to 15,122 ha in the early 1990s (Zheng et al. 2003; Fan 2000). Since the late 1970s, governments worldwide have adopted a series of measures to restrain the degradation and loss of mangroves. Mangroves have been restored, to varying extents, in the Americas (Brockmeyer et al. 1997; Lewis 2000), Oceania (Saenger 1996) and Asia (Sanyal 1998). In China, the area of mangroves ...
Through funding from the Department for International Development, the Economic and Social Research Council and the Natural Environment Research Council, researchers from Edinburgh Napier University have been working with the Kenya Marine and Fisheries Research Institute and colleagues from Bangor, Edinburgh and Birmingham Universities to conduct novel research into mangrove ecological value and ecosystem recovery. As part of their work they tracked juvenile fish to prove the key role of mangrove roots as fish habitats, and measured carbon flows in forests to calculate the significance of mangroves in absorbing atmospheric carbon. The researchers also investigated methods of ecosystem recovery, planting 5,872 trees in previously devastated land to reveal the barriers and opportunities for mangrove regeneration. This work was complemented by research into the market value of mangrove ecosystem services and how payments for these services could be adopted into conservation policy.. In 2008 the ...
Understanding the shrimp that supplies our nations voracious appetite is quite complex. Overall, the shrimp industry represents a dismantling of the marine ecosystem, piece by piece. Farming methods range from those described above to some that are more benign. Problems with irresponsible methods of farming dont end at the yuck, factor as shrimp farming is credited with destroying 38 percent of the worlds mangroves, some of the most diverse and productive ecosystems on earth. Mangroves sequester vast amounts of carbon and serve as valuable buffers against hurricanes and tsunamis. Some compare shrimp farming methods that demolish mangroves to slash-and-burn agriculture. A shrimp farmer will clear a section of mangroves and close it off to ensure that the shrimp cannot escape. Then the farmer relies on the tides to refresh the water, carrying shrimp excrement and disease out to sea. In this scenario, the entire mangrove ecosystem is destroyed and turned into a small dead zone for short-term ...

Degree granting institution Delft University of Technology. Programme Hydraulic Engineering , Coastal Engineering. Date 2018-10-31. Abstract Due to the removal of mangrove forests, coastal zones can suffer from severe erosion. One of the proposed solutions is the construction of permeable structures. This study aims to optimise the design of permeable (brushwood) structures in order to restore the sediment balance and encourage mangrove re-establishment on tropical mud coasts. Preferably wave transmission should be low in order to create a calmer climate behind the structure. In that way sediment is able to settle down, which could lead to a recovery of the mud profile. It is also preferred that reflection by the structure is low. High reflection rates cause scour holes that lead to instability of the structure. Furthermore, scour holes could hinder future mangrove re-establishment. Aiming to achieve low reflection and transmission rates, the dissipation inside the structure has to be as high as ...

Ocypodid crabs inhabit intertidal sandy/muddy flats of tropical and sub-tropical mangroves. Iran has three species of the genus Austruca. In contrast to A. sindensis and A. lactea, almost nothing is known about the population dynamics and its driving factors in Austruca iranica. Thus, population ecology and reproductive biology of A. iranica were studied in relation to sediment temperature and rainfall in a sub-tropical Iranian mangrove forest over a period of 13 months. Crab density and Gonado Somatic Index (GSI) were significantly correlated with sediment temperature (r2 = 0.87, p ≤ 0.05). Reproduction was restricted to spring and summer and ovigerous females appeared when both sediment temperature and rainfall had their maximum values. Rainfall triggered crab reproduction, but did not significantly correlate with crab density. Symptotic carapace width (L∞) and growth constant (k) were 16.9 mm and 1.0 yr. −1 in females (n = 251), and 18.5 mm and 0.9 yr. −1 in males (n = 325), ...

Ecosystem Facilitation Given the hydrodynamic environment of marine ecosystems, mangroves forests, seagrass beds and coral reefs will always be connected via the seawater to neighboring ecosystems. This connection means that there can be an exchange of physical (hydrodynamic energy), chemical (sediment and nutrient) and biological (organisms) factors. As a consequence, changes in one specific ecosystem can have consequences on neighboring ecosystems both in close proximity or (via these connections) further away. In case adjacent ecosystems improve each other growing conditions, one could speak of large-scale facilitative or positive interactions. The research in this project aims at identifying the importance of local-scale facilitating and large-scale facilitation by ecosystem (especially nutrient) connections as critical factors needed for ecosystem-based designs, ecosystem conservation and re-establishment. This objective will be met by the combination of elaborating experimentally ...

Since the 1960s, $\sim 5000~\text{km}^2$ of tidal deltaplain in southwest Bangladesh has been embanked and converted to densely inhabited, agricultural islands (i.e., polders). This landscape is juxtaposed to the adjacent Sundarbans, a pristine mangrove forest, both well connected by a dense network of tidal channels that effectively convey water and sediment throughout the region. The extensive embanking in poldered areas, however, has greatly reduced the tidal prism (i.e., volume of water) transported through local channels. We reveal that $,600$ km of these major waterways have infilled in recent decades, converting to land through enhanced sedimentation and the direct blocking of waterways by embankments and sluice gates. Nearly all of the observed closures ($\sim 98\%$) have occurred along the embanked polder systems, with no comparable changes occurring in channels of the Sundarbans ($,2\%$ change). We attribute most of the channel infilling to the local reduction of tidal prism in ...

Crustacea. In many mangroves a large proportion of the leaf litter is directly consumed by crabs, particularly those in the family Sesarmidae. This dramatically accelerates the incorporation of mangrove biomass into the food chain. The acceleration happens in three main ways:. 1. Shredding - as crabs feed on leaf litter they shred it into fine particles, increasing the surface area for leaching and microbial colonisation. An Australian study found that 20% of the material processed by crabs is dropped without being ingested (Camilleri 1989), but even this is shredded into fine particles.. 2. Accelerated leaching - 85% of the leaf litter ingested by crabs ends up in faeces. Processing of this material in the crab gut reduces content of unpalatable tannins in faeces to less than 3%, compared to 13% in freshly fallen leaves (Lee 1998). This process means that decomposing microbes can colonise the processed leaves in hours or days, rather than the weeks required without crabs.. 3. Assimilation - ...
