Amphibian Chytrid Fungus - Pinnacles National Park (U. S . . . Bd is a member of group of fungi called chytrids, which are usually found underwater growing on dead plant or animal matter Bd is the only chytrid fungus known to feed on living vertebrates It primarily affects the skin of amphibians, causing the disease known as amphibian chytridiomycosis Amphibians breathe and take up water through their skin
A global analysis of urbanization effects on amphibian . . . The impacts of urbanization on biodiversity are diverse and complex involving intricately interwoven direct and indirect effects (Parnell et al , 2013) On the one hand, the expansion of impervious surfaces directly causes habitat loss or fragmentation, which in theory would accelerate the reduction of biodiversity (Newbold et al , 2015) as isolated habitats would reduce connectivity especially
Amphibian fungal panzootic causes catastrophic and ongoing . . . Rapid spread of disease is a hazard in our interconnected world The chytrid fungus Batrachochytrium dendrobatidis was identified in amphibian populations about 20 years ago and has caused death and species extinction at a global scale
Amphibians - U. S. National Park Service These factors may cause changes in amphibian distribution, numbers, and the diversity of species at a given site (species richness) They may also cause increases in diseases and malformations Amphibians play an important role in the food web, serving as prey for many fish, reptile, bird, and mammal species and in turn eating a wide variety of
Unveiling the hidden world of amphibians in quarries Quarry ponds are ideal for supporting diverse amphibian species because they offer warm, sunlit habitats, free of fish These ponds typically have larger semi-aquatic zones, receive more sunlight, and have less shoreline vegetation than natural ponds, creating warm water perfect for breeding, especially for threatened species like the Common
Detecting Range Shrinking From Historical Amphibian Species . . . Amphibian declines, driven by climate change (e g , shifting temperatures, altered precipitation) and human activities like deforestation, agriculture, and urbanization, may lead to local extinctions Quantifying the relative impact of climate change versus human influence remains challenging This …
