The fragmentation and destruction of natural habitats by human intervention is producing a continuous and inexorable reduction of the size of populations in multitude of species all over the world. Small and isolated populations face higher extinction risks, due to demographic and environmental stochasticity, and also because of several genetic threats,(More)
BACKGROUND Studies of the phylogeography of Mexican species are steadily revealing genetic patterns shared by different species, which will help to unravel the complex biogeographic history of the region. Campostoma ornatum is a freshwater fish endemic to montane and semiarid regions in northwest Mexico and southern Arizona. Its wide range of distribution(More)
AIM The study of the factors that influence population connectivity and spatial distribution of genetic variation is crucial for understanding speciation and for predicting the effects of landscape modification and habitat fragmentation, which are considered severe threats to global biodiversity. This dual perspective is obtained from analyses of subalpine(More)
