Assessment of census (N) and effective population size (Ne) reveals consistency of Ne single-sample estimators and a high Ne/N ratio in an urban and isolated population of fire salamanders

David Álvarez, André Lourenço, Daniel Oro, Guillermo Velo-Antón. Amphibians are the most threatened vertebrates on Earth, and one of the main factors involved in their decline is the loss and fragmentation of their natural habitats. Contemporary urban development is a major cause of habitat fragmentation, and populations trapped within urban environments offer a unique opportunity to study effects of fragmentation. Here, we compared, for the first time in fire salamanders (Salamandra salamandra), estimates of census (N) and effective population size (N e ) in a small urban population in the city of Oviedo (Spain).
