Tidal creeks remain under-sampled by routine water quality monitoring programs This study developed protocols and sampling strategies suggesting how a minimal amount of effort can be valuable to evaluate tidal creek condition. Recommendations are provided for minimal sampling requirements necessary to include additional tidal creeks currently without data into this assessment, as well as future efforts to enhance the development of biological and landscape metrics to further refine the assessments of tidal creek condition. Until such time, the revised management framework and development of additional indicators of tidal creek condition serve as valuable decision support tools that can be used to prioritize resource management responses to increase the stewardship and protection of these critical coastal habitats. ...

The Wouri estuary, or Cameroon estuary is a large tidal estuary in Cameroon where several rivers come together, emptying into the Bight of Biafra. Douala, the largest city in Cameroon, is at the mouth of the Wouri River where it enters the estuary. The estuary contains extensive mangrove forests, which are being damaged by pollution and population pressures. The estuary lies to the east of Mount Cameroon and empties into the Bight of Biafra. It is fed by the Mungo, Wouri and Dibamba rivers. The estuary lies in the Douala Basin, a low-lying depression about 30 metres (98 ft) on average about sea level, with many creeks, sand bars and lagoons. The Plio-Pleistocene Wouri alluvial aquifer, a multi-layer system with alternating sequences of marine sands and estuarine mud and silt lies below the estuary and surrounding region and is an important source of well water. The upper aquifer in this system is an unconfined sandy horizon that is hydraulically connected to the brackish waters of the estuary ...

Mangrove sediment is a net sink for dissolved inorganic nitrogen (DIN) and (PN) particulate nitrogen (Alongi, 1996). Nutrient uptake is driven by high rates of plant productivity and microbial activity. N-fixation (incorporation of atmospheric N2 to form nitrogenous organic compounds) is active in the root-zone and contributes to the dissolved inorganic nitrogen (DIN) pool (Kristensen et al., 1998). Some N is liberated to the atmosphere as N2 gas through denitrification (Rivera-Monroy et al., 1996, Trott et al., 2000). Particulate nitrogen (PN) is typically processed by sediment-dwelling biota such as crabs, or is exported to the coastal waters in the form of leaf litter and fine particulate matter (Ayukai et al., 1998). This material is redistributed during ebb tides and may be exported from the tidal creek.. ...

We continued our tidal creek import/export measurements during the 2017 field season.

My research aims to shed light on the biogeochemical key roles mangroves play within the complex tropical coastal systems as a carbon sink and nutrient sources. This research is quantifying the dynamics of carbon (C) nitrogen (N), and phosphorus (P) in a tropical mangrove tidal creek located in South Vietnam (Can Gio UNESCO Biosphere Reserve). Mangrove forests are overlooked ecosystems which have developed unique physiological processes able to produce, sequester and release globally significant amount of ecologically important elements such as C, N, and P. The study employs a multi-isotope approach (d13CPOC, d15NPON, d13CDIC, d13CDOC, d15N-NO3 & 18O-NO3) to identify the origins and movement of organic matter and dissolved elemental constituents in the mangrove surface and subsurface environment (including the water column, pore water, sediment). 24 hours time series sampling during the both dry and wet seasons, as well as during neap and spring tide cycles, will provide data to quantify of ...

Shoot organogenesis and plant regeneration were achieved on callus derived from leaf section and stem base explants of Quisqualis indica (Combretaceae). In vitro cultures were established using nodal segments obtained from mature field-grown shrubby plants. For the development of optimized protocol, different types and concentrations of plant growth regulators were used to induce adventitious shoot regeneration via callus from leaf section and one-node stem base explants obtained from in vitro regenerated micro shoots and direct field-grown newly flush-off shoots. The TDZ was considered to be the best among the cytokinins (6-benzyladenine (BA), 6-(?-?, dimethylallyamino purine) (2-iP) and thidiazuron (TDZ) added to the Murashige and Skoogs medium (MS) for adventitious shoot productions. A combination of 1.0 mg/L TDZ and 0.5 mg/L GA3 was most effective in stimulating callus induction and adventitious shoot regeneration from the leaf section derived calli with an average of 6 shoots per callus explant

Mangroves and tidal creeks harbour rich and varied fish assemblages composed mostly of small, juvenile, and larval individuals. Fish species that forage on the bottom or in the water column in open areas would be at greater risk of predation by visually-oriented hunters (piscivorous birds and fishes) than fish species that forage among vegetation. I studied open areas of shallow and clear stretches of two mangroves, two tidal creeks, and one inlet under freshwater influence in southeastern Brazil, and recorded morphological features and behavioural tactics that would lessen predation risks imposed to the fishes by piscivorous birds and fishes. Besides antipredator tactics of the fishes, I recorded potential visually-hunting predators at the same sites. Among the 24 fish species recorded, camouflage was the most common tactic and included crypsis (background matching and countershading) and masquerade (resemblance to decaying plant pieces). Transparency or translucency was another common form of ...

YSI Dissolved oxygen % saturation reporting can vary depending upon how the oxygen is calibrated.. For this data Oxygen percent saturation values is reported as DO%YSI at 1 ATM pressure relative to water-saturated air calibration, and additionally as DO%recalc, after detrending. Resulting metabolic fluxes are calculated from resulting oxygen concentrations relative to the saturation concentration at local atmospheric pressure (which in this case varies by less than 2% and can be neglected relative to much larger errors in advective and air-water transfer rates.. Water depth is logged in each creek using a HOBO U20 titanium water depth loggers rated to 30 ft, and combined with 2011 creek geometry transects by Will Kearney (Sergio Fagherazzis group at BU) in order to calculate cross-sectional areas as well as surface areas through which air-water gas exchange occurs, and tidal exchange of creek water between timesteps.

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 ...

Over the past 150 years, human activity has had a major impact on tidal wetlands adjoining the San Francisco Bay-Delta estuary Growing concern about the effect of this change on the ecology of the estuary has prompted Bay area managers to attempt to reclaim tidal wetlands. The Sonoma Baylands Restoration Project is designed to use dredge material to convert 348 acres from farmland to wetland. This paper describes changes to a tidal creek that flows from that restoration site to San Pablo Bay (north San Francisco Bay) through an existing tidal wetland during different phases of the project. Hydrologic measurements near the bottom of the creek and cross-creek profiles show how the creek responded to non-tidal flow conditions introduced by filling the site with dredge materials. At the time of this study, the creek had deepened by approximately 40 cm but had not widened....

View more ,Microalgal blooms can result from anthropogenic nutrient loadings in coastal ecosystems. However, differentiating sources of nutrients remains a challenge. The response of phytoplankton and benthic microalgae (BMA) to nutrient loads was compared across tropical tidal creeks with and without secondary treated sewage. Primary productivity in the water column was limited by nitrogen availability in absence of sewage, with nitrogen saturation in the presence of sewage. Phytoplankton primary productivity rates and chlorophyll a concentrations increased in response to sewage, and there was a greater response than for BMA. There was no change in algal pigment proportions within the phytoplankton or BMA communities. Concentrations of the sewage marker, coprostanol, were higher near sewage discharge points decreasing downstream, correlating with a decline in nutrient concentrations. This suggests that sewage was the main source of nitrogen and phosphorus. This study highlights the scale and ...

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

The Site is an alluvial fan formation close to the border with Mali, which features seasonal rivers and lakes, and also artificial wetlands such as seasonally flooded agricultural land and water storage areas. The ecosystem is dominated by dry forests occupying closed micro-depressions, connected by channels which ensure their water supply. The temporary water bodies spread in winter and are absorbed into the soil when the dry season starts. The landscape is notable because of the size of the floodplain and the dense vegetation dominated by spiny shrub and Combretaceae. The vegetation also extends as gallery forest upstream beyond Banh. The vegetation hosts species such as warthog, crocodile and jackal. It is a refuge for thousands of birds including francolin and guinea fowl, and migratory birds coming (according to the farmers) from the inner delta of the Niger River. The Site also attracts livestock farmers; the end of the rainy season and the drying up of the temporary ponds leads to a ...

Analysis of high-resolution (1-4 kHz) seismic chirp profiles of the New Jersey mid-outer continental shelf, coupled with sediment samples, reveal the stratigraphic architecture resulting from the last glacio-eustatic cycle: dendritic (fluvial?) channel systems truncated by a transgressive ravinement. Quantitative geomorphologic analysis of these systems provides estimates of paleo-hydrologic parameters needed to link channel morphology to the hydrodynamic setting when these systems were active. These channels were presumably fluvial systems developed on a subaerial shelf during the Last Glacial Maximum (LGM), ~22-20 ka. During ensuing Holocene sea-level rise, these fluvial channels became estuarine/tidal, before erosion and final burial. Mean tidal paleoflow estimates for these systems with flow velocities of 1.0-1.5 m/s and shear stresses sufficient to initiate transport of grains 2-8 mm in diameter (i.e., coarse sand and fine gravel) as bed-load, are consistent with modern tidal creeks of the ...

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, ...

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 officinalis was tested for bioactivity against seven bacteria.. ...

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, ...

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

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

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 ...

Objective: The present study was undertaken to evaluate in-vitro antimicrobial activity of methanol, acetone and N, N-dimethylformamide extracts from leaf of Terminalia catappa L. (Combretaceae). Methods: In vitro antimicrobial activity of all the extracts was done by agar disc diffusion assay. 91 clinically important strains were used for the study, which were both clinical isolates as well as identified strains. Piperacillin and gentamicin were used as standards for antibacterial assay, while nystatin and flucanazole were used as standards for antifungal assay. Antimicrobial activity was determined by measurement of inhibition zone around each paper disc. For each extract three replicate trials were conducted against each organism. Results: The antibacterial activity was more pronounced against bacteria than fungal strains. The Gram positive bacteria were more susceptible than Gram negative bacteria. The methanol extract showed best antibacterial activity. T. catappa leaf extracts showed better

Criticisms voiced about the earlier volumes apply equally strongly to the present one: poor editing and very high numbers of printing errors (especially disturbing in a number of generic names), and more seriously lack of synthesis and discussion of what the diversity in venation patterns described actually means for the classification of the families and genera. For instance, questions like - does Strephonema stand apart in the Combretaceae? - is the much debated separation of the Anisophylleaceae from the Rhizophoraceae supported by divergent venation patterns? - etc., are hardly or not addressed. However, the grouping of species at the end of the book is most interesting. It shows wide ranges of variation in certain genera (e.g. Terminalia, which has species in 9 very different venation pattern groups) and very unexpected combinations of families within some of the venation groups. One consequently wonders about the systematic value of venation patterns and about the way venation patterns are ...

The antiprotozoal activity of the Ethiopian medicinal plant Combretum molle (R. Br. ex G. Don.) Engl & Diels (Combretaceae) was evaluated by in vitro testing against Plasmodium falciparum, Trypanosoma brucei rhodesiense, Trypanosoma cruzi and Leishmania donovani. The acetone fraction of the stem bark of this plant prepared by soxhlet extraction was inactive against the intracellular amastigotes of L. donovani and T. cruzi in murine peritoneal macrophages but showed significant activity against extracellular T. b. rhodesiense blood stream form trypomastigotes and trophozoites of P. falciparum with IC(50) values of 2.19 and 8.17 microg/mL, respectively. Phytochemical examination of the bioactive fraction resulted in the isolation of two tannins and two oleanane-type pentacyclic triterpene glycosides. One of the tannins was identified as the ellagitannin, punicalagin, whilst the structure of the other (CM-A) has not yet been fully elucidated. The saponins that were characterized as arjunglucoside ...

When co-injected with ceftazidime in HPLC, the retention time of the impurity was the same as the ceftazidime sample containing the impurity. The structural determination of the suspected impurity was conducted by IR, MS, 1H-NMR and 13C-NMR spectroscopic techniques. This new impurity was the methyl ester of ceftazidime, and its structure was determined as (6R, 7R)-7-[[(Z)-2-(2-aminothiazol-4-yl)-2-[(1-methoxycarbonyl-1-methylethoxy) imino]acetyl]amino]-8-oxo-3-[(1-pyridinio)methyl]-5-thia-1-azabicyclo[4.2.0] oct-2-ene-2-carboxylate, with molecular formula of C23H 24N6O7S2 and molecular weight of 560 Da.

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 ...

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 ...

We have early engineers and land speculators to thank for making Charleston what it is today-a landmass nearly twice its original size. Over the past three centuries, the shape of the Charleston peninsula has evolved dramatically. Residents and city planners used a variety of means and materials to create more buildable land and a harder border between the city and the ever-present tidal rivers that brought cooling breezes, erosion, and flooding potential in equal measure. Early settlers and visitors to Charlestown built on the highest part of the peninsula first, on the banks of the Cooper River, wedged between two large tidal creeks: Daniels Creek (what became Market Street to the north) and Vanderhorst Creek (now Water Street to the south). And as tensions between the English colonists in Carolina and the Spanish in Florida ran high, the colonial government fortified the town and built a wall around the most settled area. Alexander Hewatt described the town in 1779: It is situated on a neck ...

Yes, thats the code that I thought of as well, and same, Id have to get my head around the exact order of p_is_s (unfortunate name), etc. When you say the bug is present in ncurses 5.9, is there any application that is directly affected? I ask as screen being affected was sort of a fluke. Its configure script should have detected terminfo notation was available for use, and used the equivalent entry for cs. So Im wondering if there are many applications still out there that are trying to use the older, more terse termcap form? And also linking in with ncurses? Seems unlikely, as I would have expected that if there were, and any were using a cap entry with %i that there would have been obvious presentation problems. -- Regards.
