Contrasting demographic trends and asymmetric migration rates in a spatially structured amphibian population

Natural populations often persist at the landscape scale as metapopulations, with breeding units (subpopulations) experiencing temporal extinction and recolonization events. Important parameters to forecast population viability in these systems include the ratio of the effective number of breeders (Nb) to the total number of adults (Na) and migration rates among subpopulations. Here we present the results of a 10‐year integrative monitoring program of a metapopulation of the Iberian green frog (Pelophylax perezi) in central Spain. Leer más.
