Many studies have described the effects of urbanization on species richness. These studies
indicate that urbanization can increase or decrease species richness, depending on several …

Habitat loss and fragmentation are among the largest threats to amphibian populations.
However, most studies have not provided clear insights into their population-level …

▪ Abstract Declines and losses of amphibian populations are a global problem with complex
local causes. These may include ultraviolet radiation, predation, habitat modification …

Greater than 70% of the world's amphibian species are in decline. We propose that there is
probably not a single cause for global amphibian declines and present a three-tiered …

Amphibian populations are declining globally at an alarming rate. Pesticides are among a
number of proposed causes for these declines. Although a sizable database examining …

Urbanisation currently threatens over one-third of the world's known amphibian species. The
main threats of urbanisation to amphibian populations are habitat loss, habitat fragmentation …

For over 350 million years, thousands of species of amphibians have lived on earth, but
since the 1990s they have been disappearing at an alarming rate, in many cases quite …

Management of amphibian populations to reverse recent declines will require defining high‐
quality habitat for individual species or groups of species, followed by efforts to retain or …

Habitat destruction and fragmentation have been identified as possible causes of large-
scale amphibian declines. Here, we examine the effects of adjacent land use and water …

Urbanization negatively affects natural ecosystems in many ways, and aquatic systems in
particular. Urbanization is also cited as one of the potential contributors to recent dramatic …
