Dispersal and Wetland Fragmentation
Wetlands provide habitat for a diverse array of aquatic and semiaquatic species, many of which provide direct economic and recreational value (Woodward and Wui 2001). Despite the provided by wetland fauna and flora, ecosystem services historical wetland loss has been dramatic. Wetland loss was >50% in the U.S. and 60-70% in Europe by the 1980s, with most losses resulting from agriculture and ur...

متن کاملHow Predation and Landscape Fragmentation Affect Vole Population Dynamics
BACKGROUND Microtine species in Fennoscandia display a distinct north-south gradient from regular cycles to stable populations. The gradient has often been attributed to changes in the interactions between microtines and their predators. Although the spatial structure of the environment is known to influence predator-prey dynamics of a wide range of species, it has scarcely been considered in r...
متن کاملClimatic change and wetland desiccation cause amphibian decline in Yellowstone National Park.
Amphibians are a bellwether for environmental degradation, even in natural ecosystems such as Yellowstone National Park in the western United States, where species have been actively protected longer than anywhere else on Earth. We document that recent climatic warming and resultant wetland desiccation are causing severe declines in 4 once-common amphibian species native to Yellowstone. Climate...
