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

Amphibians have declined dramatically in many areas of the world. These declines seem to
have worsened over the past 25 years and amphibians are now more threatened than either …

For many species, not all required resources are contained in breeding habitat. Such
species depend on landscape complementation, ie, linking together different landscape …

Climate changes may be influencing the breeding patterns of certain organisms. Effects on
breeding activities could eventually lead to significant changes in population structure that …

Even among widespread species with high reproductive potentials and significant dispersal
abilities, the probability of extinctions should be correlated both with population size …

Though a third of amphibian species worldwide are thought to be imperiled, existing
assessments simply categorize extinction risk, providing little information on the rate of …

A large number of factors are known to affect amphibian population viability, but most
authors agree that the principal causes of amphibian declines are habitat loss, alteration …

Urban development is a major cause of habitat loss and fragmentation. Few studies,
however, have dealt with fragmentation in an urban landscape. In this paper, we examine …

Pond‐breeding amphibians are affected by site‐specific factors and regional and landscape‐
scale patterns of land use. Recent anthropogenic landscape modifications (drainage …

Widespread amphibian declines were well documented at the end of the 20th century,
raising concerns about the need to identify individual and interactive contributors to this …
