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

The extensive development of surface and subsurface drainage systems to facilitate
agricultural production throughout North America has significantly altered the hydrology of …

Geographically isolated wetlands (GIWs), those surrounded by uplands, exchange
materials, energy, and organisms with other elements in hydrological and habitat networks …

Reports of malformed amphibians and global amphibian declines have led to public
concern, particularly because amphibians are thought to be indicator species of overall …

While most efforts at biodiversity conservation have focused primarily on protected areas
and reserves, the unprotected lands surrounding those area—the" matrix"—are equally …

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

Terrestrial habitats surrounding wetlands are critical to the management of natural
resources. Although the protection of water resources from human activities such as …

Increased loading of nitrogen (N) and phosphorus (P) from agricultural and urban
intensification has led to severe degradation of inland and coastal waters. Lakes, reservoirs …

Amphibians are frequently characterized as having limited dispersal abilities, strong site
fidelity and spatially disjunct breeding habitat. As such, pond‐breeding species are often …

Most species of wetland‐dependent organisms live in multiple local populations sustained
through occasional migration. Retention of minimum wetland densities in human‐dominated …
