Extinction debt as a driver of amphibian declines: An example with imperiled flatwoods salamanders

摘要: Abstract A comprehensive view of population declines and their underlying causes is necessary to reverse species loss. Historically, in many cases, a narrow may have allowed continue, virtually undetected, for long periods time (perhaps even decades). We suggest that extinction debt likely responsible numerous most) amphibian this perspective should be incorporated into the structure research management. Extinction debt, originally proposed explain changes richness following environmental disturbance, also refer proportion populations an individual expected eventually lost because habitat change. conservation framework address focuses on threats at individual, population, metapopulation levels. This approach will help enhance, restore, protect specific processes habitats proper scale by directing management most v...
