Broad-Scale Climatic Gradients Drive Multiple Facets of Scorpion Beta Diversity in Northeastern Brazil

Posted by
  Broad-Scale Climatic Gradients Drive Multiple Facets of Scorpion Beta Diversity in Northeastern Brazil ABSTRACT Aim Beta diversity analyses clarify mechanisms structuring ecological communities, but their multidimensional facets remain poorly explored in arthropods. Here, we quantified taxonomic, phylogenetic, and functional beta diversity in scorpions, partitioned these facets into species replacement and richness differences, and evaluated the relative importance of spatial structure and environmental conditions in driving community assembly. Location Northeastern Brazil, South America. Taxon Scorpions (Arachnida: Scorpiones). Methods Taxonomic beta diversity was estimated using species presence across 70 sites in northeastern Brazil. Phylogenetic turnover was calculated from a multi-locus molecular tree, and functional beta diversity was derived from morphometric and ecological traits. All beta diversity facets were decomposed into replacement and richness-difference component...

Four new species of Linyphiidae (Arachnida, Araneae) from Hunan Province, China

Abstract

Four new species of the spider family Linyphiidae Blackwall, 1859 are described from Hunan Province, southern China: Gongylidioides heimifengensis sp. nov. (♂♀), Gongylidium subbifurcatum sp. nov. (♀), Gongylidium trapezium sp. nov. (♀), and Nippononeta anchorata sp. nov. (♀). Detailed descriptions, photos of habitus and copulatory organs, as well as a distribution map, are provided.
