Anuran amphibians are highly dependent on aquatic ecosystems. Many amphibian species
are exhibiting population declines primarily due to habitat destruction and water quality …

The growth of any organism depends on habitat conditions, food availability, and their
seasonal interactions. Yet in the vast literature on Pacific salmon (Oncorhynchus), the …

The decline in amphibian populations is one of the starkest examples of the biodiversity
crisis. For stream breeding amphibians, alterations to natural flow regimes by dams, water …

Almost all large rivers worldwide are fragmented by dams, and their impacts have been
modeled using the serial discontinuity concept (SDC), a series of predictions regarding …

Demographic models enhance understanding of drivers of population growth and inform
conservation efforts to prevent population declines and extinction. For species with complex …
