TL;DR: The results suggest that uniformly applying the MCP approach may lead to a one-time down listing of hundreds of species but ultimately ensure consistency across assessments and realign the calculation of EOO with the theoretical basis on which the metric was founded.
Abstract: In International Union for Conservation of Nature (IUCN) Red List assessments, extent of occurrence (EOO) is a key measure of extinction risk. However, the way assessors estimate EOO from maps of species’ distributions is inconsistent among assessments of different species and among major taxonomic groups. Assessors often estimate EOO from the area of mapped distribution, but these maps often exclude areas that are not habitat in idiosyncratic ways and are not created at the same spatial resolutions. We assessed the impact on extinction risk categories of applying different methods (minimum convex polygon, alpha hull) for estimating EOO for 21,763 species of mammals, birds, and amphibians. Overall, the percentage of threatened species requiring down listing to a lower category of threat (taking into account other Red List criteria under which they qualified) spanned 11–13% for all species combined (14–15% for mammals, 7–8% for birds, and 12–15% for amphibians). These down listings resulted from larger estimates of EOO and depended on the EOO calculation method. Using birds as an example, we found that 14% of threatened and near threatened species could require down listing based on the minimum convex polygon (MCP) approach, an approach that is now recommended by IUCN. Other metrics (such as alpha hull) had marginally smaller impacts. Our results suggest that uniformly applying the MCP approach may lead to a one-time down listing of hundreds of species but ultimately ensure consistency across assessments and realign the calculation of EOO with the theoretical basis on which the metric was founded.

TL;DR: The phylogeographical analysis of 115 greater mouse‐eared bats sampled throughout Italy shows that 15 of the 18 different haplotypes found in the mitochondrial control region of these bats were unique to the Apennine peninsula, and indicates that central Italian populations of M. myotis are more closely related to Greek samples from across the Adriatic Sea, than to other Italian bats.
Abstract: The distribution of biota from the temperate regions changed considerably during the climatic fluctuations of the Quaternary. This is especially true for many bat species that depend on warm roosts to install their nursery colonies. Surveys of genetic variation among European bats have shown that the southern peninsulas (Iberia and the Balkans) harbour endemic diversity, but to date, no such surveys have been conducted in the third potential glacial refuge area, the Apennine peninsula. We report here the phylogeographical analysis of 115 greater mouse-eared bats (Myotis myotis) sampled throughout Italy, and show that 15 of the 18 different haplotypes found in the mitochondrial control region of these bats were unique to the Apennine peninsula. Colonies within this region also showed substantial genetic structure at both mitochondrial (Phi(ST) = 0.47, P < 0.001) and nuclear markers (F(ST) = 0.039, P < 0.001). Based on a comprehensive survey of 575 bats from Europe, these genetic markers further indicate that central Italian populations of M. myotis are more closely related to Greek samples from across the Adriatic Sea, than to other Italian bats. Mouse-eared bat populations from the Apennine peninsula thus represent a complex mixture of several endemic lineages, which evolved in situ, with others that colonized this region more recently along an Adriatic route. Our broad survey also confirms that the Alps represent a relatively impermeable barrier to gene flow for Apennine lineages, even for vagile animals such as bats. These results underline the conservation value of bats from this region and the need to include the Apennine peninsula in phylogeographical surveys in order to provide a more accurate view of the evolution of bats in Europe.
