Factors Process(es)
Climate ch ange Temperature and precipitation patter ns are altered s o as to
cause disruptions in micro or macro-climatic conditions
Habitat Deforestation and agriculture; drained and filled wetlands,
modification land filling
Habitat Roads, introduced s pecies, and low pH dissect habitats,
fragmentation creating barr iers to dispersal.
Introduced species Introduced predators, pr ey on/or compete with native
amphibians.
UV-B radiation UV-B damag es and/or kills cells, causing egg mort ality,
lesions, malformations and increased susceptibility to
disease and low pH.
Chemical Toxins cause direct mortality of eggs and adults, mimic
contamination endocrine harmones, r educe th e prey base, pesticidal effect;
fluoranthene.
Acid precipitation Toxins create barrier s to dispersal and cause high egg and
and s oil larval mortality.
Disease Disease often causes death in amphibians
(Chytridiomycosis)
