valid species and 18 genetic lineages indicates that 45 (36%) of South Africa's freshwater fish taxa are threatened (7 Critically Endangered, 25 Endangered, 13 Vulnerable). Of the remaining taxa, 17 (14 ...
on neutral genetic diversity than those with smaller population sizes—such as vertebrate animals (baboon) and woody plants (orange). Image credit: Flickr users Liz West (watermelon), Ronnie Macdonald (orange ...
diversity provides the capacity for all species to adapt; without it, species cannot survive changing environments, climate change, and new pest and disease impacts. Genetic diversity is also important ...
in despeciation. Overall, new population genetics and genomics research has provided additional insight into the evolution of vertebrate species in the Galapagos. gene flow, genetic drift, hybridization, inbreeding ...
Abstract Burrowing habits or complex environments have generally been considered as potential drivers acting on reduction and loss of the appendicular skeleton among vertebrates . Herein, we suggest ...
on current genetic diversity . Many threatened and endangered species have experienced large reductions in population size, which can have a negative effect on genetic diversity (Frankham et al. 2002, Spielman ...
(Crayn et al. 2014). It is also one of the first to shed light on the ecological genetics of a threatened plant species of the diverse kwongan (Zawko et al. 2001; Byrne et al. 2014). Specifically ...
. For example, marine fish have relatively large populations compared with most terrestrial vertebrates , which is thought to make them more resilient to processes influencing their genetic diversity (Waples ...
Introduction Freshwater habitats are among the most threatened ecosystems worldwide and this is reflected in the conservation status of their biodiversity [1]. Freshwater populations have declined ...
