Fitness consequences and ancestry loss in the Apennine brown bear after a simulated genetic rescue intervention

Conservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract Reduction in population size, with its predicted effects on population fitness, is the most alarming anthropogenic impact on endangered species. By introducing compatible individuals, genetic rescue (GR) is a promising but debated approach for reducing the genetic load unmasked by inbreeding and for restoring the fitness of declining ...

Sensitivity of tropical montane birds to anthropogenic disturbance and management strategies for their conservation in agricultural landscapes

Conservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract Tropical montane bird communities are hypothesized to be highly sensitive to anthropogenic disturbance because species are adapted to a narrow range of environmental conditions and display high rates of endemism. We assessed avian sensitivity at regional and continental scales for a global epicenter of montane bird biodiversity, the tropical ...
