Global conservation prioritization often focuses on protecting the most species for the money invested (e.g., Myers et al. 2000; Orme et al. 2005; Wilson et al. 2006). Biodiversity hotspots and surrogate species are heralded as promising approaches for achieving this goal (e.g., Rodrigues et al. 2004; Bani et al. 2006; Lamoreux et al. 2006). Although identifying biodiversity hotspots (Myers et ...

Most current conservation literature focuses on the preservation of hotspots of species diversity and endemism, as if the two were geographically synonymous. At landscape scales this may not be the case. We collected data from 367 1000-m2 plots in the Grand Staircase–Escalante National Monument, Utah, USA, to show that: (1) the vast majority of plant species are locally rare; (2) species-rich a...

Based on a cladistic biogeographic analysis of 6 species-level phylogenies of harvestman taxa, we searched for congruence in the historical relationships of 12 areas of endemism of the Brazilian Atlantic Rain Forest. We constructed general area cladograms using Primary Brooks Parsimony Analysis (BPA), BPA of nodes, and paralogy-free subtree analysis. These analyses resulted in 6 general area cl...

Summary Two new species are described from the proposed Mulanje-Namuli-Ribáuè Centre of Endemism. Isoglossa perdita I.Darbysh. (Acanthaceae) is apparently restricted to submontane forests southeastern Mt Mulanje in Malawi, and assessed as Critically Endangered. Agelanthus patelii Polhill & Timberlake (Loranthaceae) recorded montane Namuli Mozambique, earlier assessment this Endangered confi...

An area of endemism (AOE) is a complex expression of the ecological and evolutionary history of a species. Here we aim to address the principal drivers of avian diversification in shaping patterns of endemism in China by integrating genetic, ecological, and distributional data on the Red-headed Tree Babbler (Stachyridopsis ruficeps), which is distributed across the eastern Himalayas and south C...

We investigated species diversity and distribution patterns of the marine red alga Portieria in the Philippine archipelago. Species boundaries were tested based on mitochondrial, plastid and nuclear encoded loci, using a general mixed Yule-coalescent (GMYC) model-based approach and a bayesian multilocus species delimitation method. The outcome of the GMYC analysis of the mitochondrial encoded c...

Endemism, which is typically high on islands and in caves, has rarely been studied in the cave entrance ecotone. We investigated the endemism of the spider genus Uthina at cave entrances. Totally 212 spiders were sampled from 46 localities, from Seychelles across Southeast Asia to Fiji. They mostly occur at cave entrances but occasionally appear at various epigean environments. Phylogenetic ana...

Using complementary metrics to evaluate phylogenetic diversity can facilitate the delimitation of floristic units and conservation priority areas. In this study, we describe the spatial patterns of phylogenetic alpha and beta diversity, phylogenetic endemism, and evolutionary distinctiveness of the hyperdiverse Ecuador Amazon forests and define priority areas for conservation. We established a ...

The ragged topography created by orogenesis generates diversified habitats for plants in Taiwan. In addition to colonization from nearby mainland China, high species diversity and endemism of plants is also present in Taiwan. Five of the seven Scutellaria species (Lamiaceae) in Taiwan, for example, are endemic to the island. Hypotheses of multiple sources or in situ radiation have arisen to exp...

Rarely have studies assessed Odonata diversity for the entire Nearctic realm by including Canada, United States, and Mexico. For first time, we explored in this region according to a definition of natural community assemblages generated species distribution models (SDMs). Species occurrence data were assembled reviewing databases specimens held significant repositories through an extensive sear...
