Comparative analysis of pollen counts of Corylus, Alnus and Betula in Szczecin, Warsaw and Lublin (2000-2001). (1/18)

The aim of the study was to compare the airborne concentrations of allergenic pollen produced by three early flowering tree taxa (Corylus, Alnus, Betula) in the cities of Warsaw (central Poland), Lublin (eastern Poland) and Szczecin (western Poland) during the years 2000-2001. Measurements were performed by the volumetric method. Pollen seasons were defined as the periods in which 95% of the total catch occurred. The highest concentration and annual pollen count of Corylus was measured in Lublin in both seasons, while the highest annual pollen counts of Alnus and Betula were noted in Warsaw, where the annual pollen count of Betula in 2001 was four times higher than in 2000 and equalled 5,376 grains in m3 per 24 h. Significant differences in the pollen count of the examined taxa were observed between two seasons: the pollen count of Corylus was higher in 2000 than in 2001, while for Alnus and Betula the opposite was the case. The longest pollen seasons were observed at low annual pollen counts for the pollen of Corylus. Results of the study reveal significant differences between the seasons and the cities. The differences concern the dates of the appearance of pollen grains in the air, the duration of the presence of sporomorphs and the maximum concentrations in particular seasons. The pollen counts of alder, birch and hazel trees are determined by the weather, diversity of local flora and specific rhythm of pollination of particular taxa.  (+info)

Bacteria associated with hazelnut (Corylus avellana L.) decline are of two groups: Pseudomonas avellanae and strains resembling P. syringae pv. syringae. (2/18)

A total of 118 fluorescent pseudomonads associated with hazelnut decline, which has been occurring for many years in different areas of northern Greece and Italy, were assessed by performing a repetitive PCR analysis with enterobacterial repetitive intergenic consensus, box element, and repetive extragenic palindromic primer sets, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of whole-cell protein extracts, a carbon compound utilization analysis, and an analysis to determine the presence of the syrB gene. A subset of 53 strains was also characterized by amplified 16S ribosomal DNA restriction analysis (ARDRA) by using nine restriction endonucleases. The virulence of 40 representative strains was assessed by using serial doses. The pathogenic specificities of the strains were also verified. ARDRA carried out with HinfI revealed two main groups of strains, groups A and B, which exhibited a level of similarity of 57%. The other eight restriction endonucleases used did not separate the strains. In addition, a cluster analysis performed by the unweighted pair group method using arithmetic averages after repetitive PCR and SDS-PAGE of protein extracts also revealed the same two groups. Furthermore, the differential utilization of some carbon compounds made it possible to differentiate the groups. Virulence assessment clearly indicated that the group A strains are very virulent, whereas the group B strains proved to be mildly virulent for hazelnut. Group A included the strains isolated in northern Greece and central Italy (i.e., the province of Viterbo); these strains do not have the syrB gene, are pathogenically restricted to Corylus avellana, and belong to Pseudomonas avellanae. Group B includes the other strains obtained from hazelnut cultivated in Piedmont, Campania, Latium, Sicily, and Sardinia. They represent a distinct taxon closely related to Pseudomonas syringae pv. syringae.  (+info)

Differences in spatial autocorrelation between four sub-populations of Alnus trabeculosa Hand.-Mazz. (Betulaceae). (3/18)

To investigate the spatial structure of Alnus trabeculosa Hand.-Mazz, we compared three sub-populations at Imaichi in Tochigi Prefecture and one sub-population at Juo in Ibaraki Prefecture, Japan. A total of 269 trees, covering 0.71 ha in total, were mapped and genetically analyzed using nine enzyme systems encoding 13 isozyme loci. There were no significant differences between the four sub-populations in terms of Na,Ne, H(o), H(e )and F(IS). However, according to spatial autocorrelation analysis, the Juo sub-population, which is younger than the others, showed an aggregation of multilocus genotypes, especially within 25 m radii. In contrast with the Juo sub-population, those in Imaichi showed no clear spatial structuring. In the three Imaichi sub-populations, gametic phase disequilibrium is attributable to heterogeneity of genotype frequencies, but in the Juo sub-population it seems to be due to other factors, connected with the composition of the trees in the sub-population and/or its founder population, gene flow and asexual propagation. To conserve as much as possible of the genes or genotypes in restricted areas, conservation of populations that do not show clear family structures, such as those in Imaichi, would be most effective.  (+info)

Isozyme polymorphisms provide evidence of clinal variation with elevation in Nothofagus pumilio. (4/18)

Variable physical conditions along elevational gradients strongly influence patterns of genetic differentiation in tree species. Here, the hypothesis is tested that different growth forms of Nothofagus pumilio, which characterizes the subalpine forests in the southern Andes, will display continuous genetic variation with elevation. At each of four elevational strips in three different mountain ranges, fresh leaf tissue was sampled from 30 randomly selected individuals to be analyzed by protein electrophoresis. Allelic frequencies were used to test for heterogeneity across populations and to classify populations into different elevational strips by discriminant analysis. The degree of population divergence was estimated by F(ST). Clinical variation on within-population genetic characteristics was analyzed by linear regressions against elevation. Seven enzyme systems coded for 14 putative isozyme loci, 57% of which were polymorphic in at least one population. Allele frequencies significantly varied with elevation and discriminant analysis separated populations at different elevational strips. Among-population divergence within any mountain range was small, but greater than among different mountain ranges. Overall, low-elevation populations were more variable than high-elevation populations, and regression analyses suggested continuous variation in populations of N. pumilio 100 m apart. Marked stepwise phenological differences on mountain slopes are most probably responsible for the isolation of nearby populations.  (+info)

Ecological and genetic effects of cutting in an Alnus trabeculosa Hand.-Mazz. (Betulaceae) population. (5/18)

In order to assess the ecological and genetic effects of cutting, we compared two portions of Alnus trabeculosa population at Yuda (Iwate Prefecture, Japan): one that has been cut about 30 years ago and one that has remained uncut. These portions were compared in terms of the degree of sprouting, genetic variation and gene distribution using isozyme markers. First, we determined the multilocus genotype (MLG) of all ramets, then sorted them into individuals according to the distribution of the MLGs. The average (+/- SE) of largest distance between ramets in one individual was 2.1 (+/- 0.18) m, which is consistent with the distance (2.0 (+/- 0.20) m) obtained by tracing physical connections between ramets. We found no significant differences in genetic variation between the two portions, but there were significant differences in their degree of sprouting. Furthermore, there were striking differences in gene distribution: the cut portion showed greater clustering of individuals with identical genetic components, which may be due to regeneration in the gaps made by cutting, reflecting the location of the mother trees, and seed and pollen dispersal from them.  (+info)

Self-organized origami. (6/18)

In origami, form follows the sequential spatial organization of folds. This requires continuous intervention and raises a natural question: Can origami arise through self-organization? We answer this affirmatively by examining the possible physical origin for the Miura-ori leaf-folding patterns that arise naturally in insect wings, leaves, and other laminae-like organelles. In particular, we point out examples where biaxial compression of an elastically supported thin film, such as that due to differential growth, shrinkage, desiccation, or thermal expansion, spontaneously generates these patterns, and we provide a simple theoretical explanation for their occurrence.  (+info)

Carbon flux and growth in mature deciduous forest trees exposed to elevated CO2. (7/18)

Whether rising atmospheric carbon dioxide (CO2) concentrations will cause forests to grow faster and store more carbon is an open question. Using free air CO2 release in combination with a canopy crane, we found an immediate and sustained enhancement of carbon flux through 35-meter-tall temperate forest trees when exposed to elevated CO2. However, there was no overall stimulation in stem growth and leaf litter production after 4 years. Photosynthetic capacity was not reduced, leaf chemistry changes were minor, and tree species differed in their responses. Although growing vigorously, these trees did not accrete more biomass carbon in stems in response to elevated CO2, thus challenging projections of growth responses derived from tests with smaller trees.  (+info)

Rising atmospheric CO2 reduces sequestration of root-derived soil carbon. (8/18)

Forests have a key role as carbon sinks, which could potentially mitigate the continuing increase in atmospheric carbon dioxide concentration and associated climate change. We show that carbon dioxide enrichment, although causing short-term growth stimulation in a range of European tree species, also leads to an increase in soil microbial respiration and a marked decline in sequestration of root-derived carbon in the soil. These findings indicate that, should similar processes operate in forest ecosystems, the size of the annual terrestrial carbon sink may be substantially reduced, resulting in a positive feedback on the rate of increase in atmospheric carbon dioxide concentration.  (+info)

Abstract. Natural populations of Carpinus orientalis Mill. Shrub lands occur mainly in high and middle altitudes of the Hyrcanian forests, N. Iran, particularly on steep rocks and forest outcrops. There are some discrepancies on the intra-specific delimitation of this important woody species. The aim of the current study was to examine the anatomical variation of stems and leaves of sixteen populations of Carpinus orientalis collected in four north and northeastern provinces of Iran for the first time. Also this study show that anatomical characters of stem showed the highest correlation to climatic factors include temperature, altitude and precipitation and midrib anatomical characters did not show any relationship.

Examining environmental and management effects on crop quality draws on plant-defense theories of chemical ecology as well as the related area of secondary metabolite chemistry. According to plant-defense theories, plants are continuously exposed to a plethora of abiotic and biotic stresses in their environment such as pathogens, herbivores, and ultraviolet radiation. As sessile organisms, plants can not protect themselves from these stress factors through movement and have evolved secondary metabolites as defense compounds to protect themselves from various abiotic and biotic stresses (Fraenkel, 1959; Feeny, 1976; Coley et al., 1985; Harborne, 1993) such as mediating interactions with pathogens and other organisms (Piasecka et al., 2015). Some secondary metabolites also serve as signal compounds to attract pollinating and seed-dispersing animals (Wink, 2015). Unlike primary metabolites (e.g. carbohydrates, lipids, proteins) that are ubiquitous across the plant kingdom for their crucial role in ...
Bøkeordenen (Fagales) er en orden av blomsterplanter som omfatter mange av de mest kjente løvtrærne. Artene er løvfellende eller eviggrønne busker og trær. De enkjønnede blomstene er samlet i blomsterstander som kalles rakler. Nesten alle er sambu og vindpollinerte. Frukten har bare ett frø. Den opprinnelige frukttypen er en samara, som spres med vinden. Nøtter, som spres med dyr, er utviklet minst sju ganger innen ordenen. I Cronquist-systemet omfattet ordenen fem familier: Balanopaceae, Ticodendraceae, bøkefamilien (Fagaceae), sydbøkfamilien (Nothofagaceae) og bjørkefamilien (Betulaceae). Hasselfamilien (Corylaceae) ble ofte skilt ut fra bjørkefamilien, og Ticodendraceae ble ikke oppdaget før i 1989. I nyere systematikk er jerntrefamilien (Casuarinaceae) flyttet hit fra Casuarinales, valnøttfamilien (Juglandaceae) og Rhoipteleaceae fra Juglandales og porsfamilien (Myricaceae) fra Myrtales. Balanopaceae er derimot flyttet til Malpighiales. I APG III-systemet er Rhoipteleaceae ...

The belief that Lophiomys is poisonous has long been current in Kenya [2,5,6]. Of particular interest is a tract of hairs that are of unique structure. We have confirmed the suggestion that this tract of hairs can acquire toxic properties and we assert here that they, together with other specialized behavioural, morphological and anatomical adaptations, have led to a powerful defence, highly unusual for a mammal. Flaring of the fur is triggered by external interference or attack on the animal, whereupon white and black banding of the longer hairs on either side of the lateral line effects outlines of the tract in a bold white and black target design. An aggravated rat pulls its head back into its shoulders and turns its flared tract towards its adversary as if actively soliciting an attack. This display may or may not be accompanied by vocalizations.. A complex of defensive traits in the crested rat would have evolved against natural predators; however, most reliable observations about their ...
Since the year 2000, the world elderly population increased by 48%. Medical problems become more predominant with aging leading to polypharmacy. Biological changes can occur with aging resulting in increased susceptibility of older people to medications and their side effects. These changes may have greater effect in a frail person or person with number or long-term or chronic diseases and conditions. Atorvastatin, rosuvastatin, perindopril, amlodipine and paracetamol are commonly used medications among elderly. This paper has reviewed clinical trials and publications on these medications among elderly. It has been found that the safety and effectiveness of these medications among elderly had been evaluated with the main focus on the effectiveness of these medications on different medical conditions and less focus on the effects of the elderly pharmacokinetics and pharmacodynamic changes on these medications. Thus, more clinical trials are required to test elderly biological changes effects on ...

The North Eastern region of India is undergoing industrial development at a faster rate than expected. Roads form the main system of transportation and communication owing to the hilly topography of the region. Automobiles discharge a number of gaseous and trace metal contaminants. Human activities like stone grinding, road construction and sand milling also increase the atmospheric dust and heavy metal contaminant level. These contaminants get settled on leaf surfaces at roadsides and enter in contact with phylloplane microorganisms. This study compares microorganisms on leaf surfaces of alder (Alnus nepalensis (Betulaceae)) on roadside and non-roadside environments. Two sites dominated by alder were selected. One at a busy road intersection on the National Highway no. 44 in Shillong with high traffic density (8000-9000 heavy vehicles/day), taken as the polluted site and the other one in a forest approximately 500 m away from the roadside considered as the unpolluted site.

Proteoid roots, also known as cluster roots, are plant roots that form clusters of closely spaced short lateral rootlets. They may form a two- to five-centimetre-thick mat just beneath the leaf litter. They enhance nutrient uptake, possibly by chemically modifying the soil environment to improve nutrient solubilisation.[1] As a result, plants with proteoid roots can grow in soil that is very low in nutrients, such as the phosphorus-deficient native soils of Australia.. They were first described by Adolf Engler in 1894, after he discovered them on plants of the family Proteaceae growing in Leipzig Botanic Gardens. In 1960, Helen Purnell examined 44 species from ten Proteaceae genera, finding proteoid roots in every genus except Persoonia; she then coined the name proteoid roots in reference to the plant family in which it was known to occur.[2] Proteoid roots are now known to occur in 27 different Proteaceae genera, plus around 30 species from other families, including Betulaceae, ...
The effects of soil incorporated lime and K on the concentrations of N, P, K, Ca, Mg, Mn, Fe, Cu, B and Zn in the leaves of filbert trees (Corylus aveliana L. cv Barcelona) were investigated. One year old filbert trees of uniform size were grown in Laurelwood clay loam (L) and Jory silt clay loam (J) in five-gallon plastic pots. The L soil was high in exchangeable K, while soil J was low in exchangeable K as determined by soil tests. Lime treatments were made to bring the initial pH of each soil up to pH 6.6 and 7.1 respectively. Potassium treatments were calculated to bring the soil test levels to intermediate and high levels. Lime significantly increased the leaf concentration of K, Ca, Mg, Fe, Cu, and Zn and decreased that of P, Mn, and B. Potassium treatments resulted in a significant increase in the leaf concentration of K, Mn, and a decrease in P, Mg, and Cu, but had no effect on the concentration of Fe, B, Zn and N. There were highly significant linear relationships between applied lime ...

Climate change is impacting food and beverage crops around the world with implications for environmental and human well-being. While numerous studies have examined climate change effects on crop yields, relatively few studies have examined effects on crop quality (concentrations of nutrients, minerals, and secondary metabolites). This review article employs a culturally relevant beverage crop, tea (Camelia sinensis), as a lens to examine environmental effects linked to climate change on the directionality of crop quality. Our systematic review identified 86 articles as relevant to the review question. Findings provide evidence that shifts in seasonality, water stress, geography, light factors, altitude, herbivory and microbes, temperature, and soil factors that are linked to climate change can result in both increases and decreases up to 50% in secondary metabolites. A gap was found regarding evidence on the direct effects of carbon dioxide on tea quality, highlighting a critical research area for
Phosphorus inputs to agriculture and their fate in the environment contribute to poor water quality and degradation of linked ecosystem services at great cost to society. Climate change is likely to alter the forms and timings of P fluxes from land to water and their ecological impact, the effects of which are uncertain and need to be considered to inform future catchment management for eutrophication control. The P transfer continuum is an established conceptual model that we propose as a suitable framework to consider the potential effects of climate change on catchment P transfer. Consideration of this continuum suggests that predicted changes in temperature and precipitation will likely increase P transfer and associated eutrophication costs in some regions. Further research should examine climate change effects on each tier of the continuum to inform the necessary land management adaptations and transformations to ensure future food system P efficiency and resilience.. ...

My general research focus on size dependent predatory and competitive interactions within and between fish species and how these, together with abiotic factors, affect the size structure, density, production and dynamics of fish populations and fish communities. More specifically, present main research approaches focus on how fish populations, fish communities and ecosystems are affected by climate change and fisheries. The climate change research integrates studies of abiotic factors and its impact on biotic processes, focusing on identifying mechanisms and thresholds of climate change effects on fish production and ecosystem productivity. Key aspects of this research are how temperature, light availability and concentrations of terrestrial organic carbon affect productivity, resource use and energy pathways in aquatic food webs, from algae and bacteria at the base of the food web, through intermediate consumers (zooplankton and macroinvertebrates) to top consumers like fish.. The research on ...
My general research focus on size dependent predatory and competitive interactions within and between fish species and how these, together with abiotic factors, affect the size structure, density, production and dynamics of fish populations and fish communities.

Climate change is expected to not only raise water temperatures, but also to cause brownification of aquatic ecosystems via increased inputs of terrestrial dissolved organic matter. While efforts have been made to understand how increased temperature and brownification separately influence aquatic food webs, their interactive effects have been less investigated. Further, although climate change effects on aquatic ecosystems likely will propagate to terrestrial consumers via changes in aquatic insect emergence, this has rarely been studied. We investigated the effect of climate change on aquatic insect emergence, in a large-scale outdoor pond facility where 16 sections - each containing natural food webs including a fish top-consumer population - were subjected to warming (3 degrees C above ambient temperatures) and/or brownification (by adding naturally humic stream water). Aquatic insect emergence was measured biweekly over 18weeks. We found no effect of warming or brownification on total ...
Risk analysis is particularly difficult in the context of environmental hazards - scientists have come up with a new, simplified risk model that might help.. Any risk analysis involves an assessment of a systems vulnerabilities, and how probable it is that a hazard will occur. Researchers have put together a simple probabilistic risk analysis tool particularly useful for predictions of climate change effects on vegetation. It has been used to examine the risk of drought in European forests, recently (1971 to 2000) and in the future (2071 to 2100).. Risk is a product of vulnerability - drought versus non-drought productivity of vegetation, in this case - and probability - of a drought, which is increasing in Southern Europe but decreasing farther north. The model looks at the uncertain effects of certain environmental variables on any given ecosystem variable. The model can be adjusted to different levels or thresholds of environmental variable hazard. Implementing the model in the case of ...

Global change drivers (GCDs) are expected to alter community structure and consequently, the services that ecosystems provide. Yet, few experimental investigations have examined effects of GCDs on plant community structure across multiple ecosystem types, and those that do exist present conflicting patterns. In an unprecedented global synthesis of over 100 experiments that manipulated factors linked to GCDs, we show that herbaceous plant community responses depend on experimental manipulation length and number of factors manipulated. We found that plant communities are fairly resistant to experimentally manipulated GCDs in the short term (,10 y). In contrast, long-term (≥10 y) experiments show increasing community divergence of treatments from control conditions. Surprisingly, these community responses occurred with similar frequency across the GCD types manipulated in our database. However, community responses were more common when 3 or more GCDs were simultaneously manipulated, suggesting ...

The weather was unseasonably wet and cold, thanks to the changing climate which gave farmers smaller crops than expected. This is something that happens, bad years are normal for any sort of agriculture for a variety of reasons. Still, climate change is making weather patterns unpredictable meaning that normal methods that farmers might employ for mitigating the damage are not always able to be done in time. We probably wont see any real impact to our beloved taters unless this continues for a few more years, which it might because, as Im sure youre aware, climate change is very real. Although we may not see another bad year for potatoes, its just as likely that we will see more. ...

The description and analysis of chemical defense mechanisms across insects, mainly in lepidopteran and coleopteran herbivores, initiated the search for general trends in the taxonomic distribution and evolution of such mechanisms. Research using empirical and manipulative tests on predator-prey systems, computational modeling, and phylogeny-based approaches has identified sequential steps in the evolution of prey defensive traits as well as plant-insect interactions (e.g., [8, 14, 85-90]). However, nearly all such studies, even when they embrace multitrophic interactions at once, focus explicitly or implicitly on (dis)advantages as well as evolutionary sequences and consequences of visual prey signals. In this context, there is good evidence that the evolution of aposematism is accompanied by an increased diversification of lineages, as shown by paired sister-group comparisons in insects and other animal taxa [91]. Further, chemical adaptation (unpalatability) preceded morphological (warning ...
Non-native plants introduced to new habitats can have significant ecological impact. In many cases, even though they interact with the same community of potential herbivores as their new native competitors, they regularly receive less damage. Plants produce secondary metabolites in their leaves that serve a range of defensive functions, including resistance to herbivores and pathogens. Abiotic factors such as nutrient availability can influence the expression of defensive traits, with some species exhibiting increased chemical defense in low-nutrient conditions. Plants in the genus Lonicera are known to produce a diverse array of these secondary metabolites, yet non-native Lonicera species sustain lower amounts of herbivore damage than co-occurring native Lonicera species in North America. In this study, we searched for evidence of biochemical novelty in non-native species, and quantified its association with resistance to herbivores. In order to achieve this, we evaluated the phenolic and iridoid

Fifteen percent of all outpatient prescriptions collected included at least one injection. Injections were prescribed either as one-off injectable analgesics, antispasmodics or anti-emetics or a complete 5-day course of injectable antibiotics administered on an outpatient basis. The proportion of general population that reported receiving an injection or IV infusion in the last 3 months was also high (19%). The average number of injections per capita per year was calculated to be 2 per person per year and since immunizations are done almost exclusively by government vaccinators, this estimate applies to therapeutic, non-insulin injections only. This estimate is higher than would reasonably be expected among similar populations in countries with well-developed health care systems and reflects the tendency of prescribers in the Northern Areas to overuse injectable drugs for disease conditions that can be managed just as well with oral alternatives. At the same time, this estimate of 2.3 injections ...

The reduction or loss of interbreeding (gene flow, sharing of mutations) between the sub-populations results in different evolutionary responses within the separated sub-populations, each then responds independently to their different ecological challenges and opportunities, and this leads to divergence of hereditary traits between the subpopulations and the frequency of their distributions within the sub-populations.. Over generations, these different responses accumulate into differences between the hereditary traits available within each of the daughter populations, and when these differences have reached a critical level, such that interbreeding no longer occurs, then the formation of new species is deemed to have occurred. After this event each daughter population evolves independently of the other/s.. An additional observable result of speciation is a branching of the genealogical history for the species involved, where two or more offspring species are each independently descended from ...
