Abstract: To analyze impacts of habitat loss on evolutionary ersity and to test widely used bio ersity metrics as surrogates for phylogenetic ersity, we study spatial and taxonomic patterns of phylogenetic ersity in a wide‐ranging endemic Neotropical snake lineage. South America and the Antilles. We updated distribution maps for 41 taxa, using species distribution models and a revised presence‐records database. We estimated evolutionary distinctiveness ( ED ) for each taxon using recent molecular and morphological phylogenies and weighted these values with two measures of extinction risk: percentages of habitat loss and IUCN threat status. We mapped phylogenetic ersity and richness levels and compared phylogenetic distances in pitviper subsets selected via endemism, richness, threat, habitat loss, biome type and the presence in bio ersity hotspots to values obtained in randomized assemblages. Evolutionary distinctiveness differed according to the phylogeny used, and conservation assessment ranks varied according to the chosen proxy of extinction risk. Two of the three main areas of high phylogenetic ersity were coincident with areas of high species richness. A third area was identified only by one phylogeny and was not a richness hotspot. Faunal assemblages identified by level of endemism, habitat loss, biome type or the presence in bio ersity hotspots captured phylogenetic ersity levels no better than random assemblages. Pitvipers found in the richest areas or included in the IUCN Red List showed significant phylogenetic clustering. Usual bio ersity metrics were unable to adequately represent spatial patterns of evolutionary ersity in pitvipers. Current Red List status fails to properly represent evolutionary distinctiveness in the group. Phylogenetic ersity is unevenly distributed even within bio ersity hotspots, and species‐poor areas may harbour high phylogenetic ersity. This reinforces the need for targeted and spatially accurate approaches for adequately representing evolutionary processes in conservation planning.

Abstract: Comprehensive assessments of species’ extinction risks have documented the extinction crisis 1 and underpinned strategies for reducing those risks 2 . Global assessments reveal that, among tetrapods, 40.7% of hibians, 25.4% of mammals and 13.6% of birds are threatened with extinction 3 . Because global assessments have been lacking, reptiles have been omitted from conservation-prioritization analyses that encompass other tetrapods 4–7 . Reptiles are unusually erse in arid regions, suggesting that they may have different conservation needs 6 . Here we provide a comprehensive extinction-risk assessment of reptiles and show that at least 1,829 out of 10,196 species (21.1%) are threatened—confirming a previous extrapolation 8 and representing 15.6 billion years of phylogenetic ersity. Reptiles are threatened by the same major factors that threaten other tetrapods—agriculture, logging, urban development and invasive species—although the threat posed by climate change remains uncertain. Reptiles inhabiting forests, where these threats are strongest, are more threatened than those in arid habitats, contrary to our prediction. Birds, mammals and hibians are unexpectedly good surrogates for the conservation of reptiles, although threatened reptiles with the smallest ranges tend to be isolated from other threatened tetrapods. Although some reptiles—including most species of crocodiles and turtles—require urgent, targeted action to prevent extinctions, efforts to protect other tetrapods, such as habitat preservation and control of trade and invasive species, will probably also benefit many reptiles.
