Dispersal and the metapopulation paradigm in amphibian ecology and conservation: are all amphibian populations metapopulations?

M Alex Smith, D M. Green - Ecography, 2005 - Wiley Online Library
Amphibians are frequently characterized as having limited dispersal abilities, strong site
fidelity and spatially disjunct breeding habitat. As such, pond‐breeding species are often …

Landscape complementation and metapopulation effects on leopard frog populations

SE Pope, L Fahrig, HG Merriam - Ecology, 2000 - Wiley Online Library
For many species, not all required resources are contained in breeding habitat. Such
species depend on landscape complementation, ie, linking together different landscape …

Effects of landscape composition and wetland fragmentation on frog and toad abundance and species richness in Iowa and Wisconsin, USA

MG Knutson, JR Sauer, DA Olsen… - Conservation …, 1999 - Wiley Online Library
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 …

An experimental investigation of landscape resistance of forest versus old‐field habitats to emigrating juvenile amphibians

BB Rothermel, RD Semlitsch - Conservation biology, 2002 - Wiley Online Library
We used an experimental approach to investigate the effects of landscape composition on
the initial dispersal success of juvenile amphibians. Larval amphibians—spotted …

Complex life cycles and density dependence: assessing the contribution of egg mortality to amphibian declines

JR Vonesh, O De la Cruz - Oecologia, 2002 - Springer
In the last decade there has been increasing evidence of amphibian declines from relatively
