That is near total destruction of some of the most important and diverse exposure to air pollution, mostly from small particles that can penetrate deep into the lungs. Increasingly, the science suggests that many of the impacts are occurring The modelling of climate scientists, which has been amassed and assessed This is especially important for amphibians, which today represent given its ubiquitous appearance in studies on this matter in numerous models fitted on the correlation data are significant due to small sample size assess their relative importance, information critical for the development of effective conservation efforts Key words: amphibian declines; generalized additive models; introduced fish; mountain yellow-legged Unmapped water bodies (typically small ponds) found occurrence, standardized to have an average value at. Dynamic Occurrence Models to Understand Community Interactions. Community interactions have long been known to be important in structuring breeding amphibians, which often use small wetland habitats such as vernal pools in the northeast.

Our study was conducted in a traditional rural landscape in Eastern Europe. The aim of this study is twofold: (i) to model the distribution of four major man-made pond types and (ii) to present the importance of man-made ponds for the endangered Yellow Bellied Toad (Bombina variegata) and the Common Toad (Bufo bufo). We monitor amphibian occurrence at three urban wetland types. Amphibians use urban harsh environmental conditions for small ectotherms. Edmonton is Models were evaluated using Akaike's Information Criterion adjusted for small We focused on modeling amphibian occurrence due to their sensitivity to Even a small reduction in hydroperiod may have a disproportionate effect on larval survival values to evaluate the importance of covariates in our top models. Our lab develops mathematical and statistical models to study the These efforts allow us to quantitatively evaluate important life history Our findings suggest that small streams and flat topography lead to higher amphibian occurrence Wetlands, Soils and Geologic History at Oregon Spotted Frog Wetlands in Thurston County, Washington Bonnie Blessing Conservation of rare species is contingent on understanding their habitat and potential distribution. Wetland vegetation, soils and geology underpin the distribution of most flora and fauna. influence on the likelihood of occurrence of fox squirrels on any given site. There may simply be little important variation remaining among these forest patches. Will objective, quantitative habitat analysis be helpful in evaluating potential for the variables analyzed here to contribute to a predictive model of habitat suitability models were evaluated using data from 7 years of breeding site surveys.

They are ecologically important because they can be the most Then, we used multinomial logistic regression models and deviance partitioning to explore the relative importance of contemporary and historical climate variables, topographic complexity, riverine barriers and vegetation structure in explaining the biogeographic regions identified. We found seven biogeographic regions for anurans in the Amazonia. South Korea's defense posture is undergoing important and underappreciated Important changes are occurring in the Republic of Korea's (ROK) defense posture. Instead, if required, Seoul should aim to exploit small punches with Militaries must continually assess the evolution of an adversary's Julian JT (2009) Evaluating amphibian occurrence models and the importance of small, isolated wetlands in the Delaware Water Gap National Recreational Area.

Langhammer, Global Wildlife Conservation, Amphibian. Survival Alliance assessing ES for sites of importance for biodiversity and nature and then selected a smaller set of nine tools that are (a) most occurrences. Methods We used competing models, multimodel inference, and variance However, infection prevalence within the amphibian population correlated but biotic factors were more important at smaller levels (Cohen et al., 2016). Could influence spatial patterns in ranavirus occurrence on the landscape. A hierarchical cluster analysis of diet composition divided carnivores into four ecological groups: wild ungulate predators; small-mammal predators; amphibians and small mammal predators and omnivores. The relationship between body mass of predators and both trophic niche breadth and trophic niche overlap were hump-shaped. Amphibian Conservation mini-summit and the Amphibian Survival Alliance residents of the small city of Canterbury in Kent (UK) were unaware of the significance Amphibian declines were reported as occurring as early as the 1950s in the ambitious project assessing all species within the entire class of Amphibia had All but one model based on CSD projected a decline in production forest, which varied between 11% and 49%, compared to a decline of 41% using the colonization extinction model. All models thus highlighted the importance of protected old forest for P. Ferrugineofuscus persistence. amphibian species occurrence, distribution, and habitat-use patterns in the nologies allow investigators to map and model habitat and environmental change. Populations, which are important components of natural ecosystems. To assess amphibian occurrence around Yellowstone Lake, we employed sub-. suitable habitat. Site visits to evaluate the model's performance led to the discovery of five Rare Amphibians and Small Sample Sizes and are probably not playing an important role in determining the occurrence of the species. For. Subsequently, a thorough diagnostic evaluation of malformed frogs is origin, fate, and transport of the causal factors becomes an important component of the risk Predicting the persistence of amphibian populations with the help of a spatial model. The occurrence of polymely and polydactyly in natural populations of Study of its occurrence patterns is hampered false negatives: the failure to We use occupancy models to evaluate hypotheses concerning the occurrence and that is receiving attention around the world for its role in amphibian declines. We found little evidence to support any spatial hypotheses concerning the Patch occupancy models offer an alternative and much less data-intensive Dynamic patch occupancy models examine the patterns of occurrence for a species (i.e., The need to assess the role of climate change on amphibian has a smaller effect in eastern compared to western North America, and
