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...

New data on spiders (Arachnida, Araneae) of the Arabian Peninsula and the Levant, with new species and records

Abstract

Based on several small collections, new taxonomic and faunistic data on spiders of the United Arab Emirates (UAE), Saudi Arabia, Kuwait, and Lebanon are presented. Six species are described as new to science: Dorceus saif Szűts & Zamani, sp. nov. (♂; Saudi Arabia), Loureedia melanconi Szűts & Zamani, sp. nov. (♂; Saudi Arabia) (both Eresidae), Leptopilos hajarensis Zamani & Marusik, sp. nov. (♀; UAE), Synaphosus dulcicola Zamani & Marusik, sp. nov. (♀; UAE) (both Gnaphosidae), Arctosa formosa Zamani & Marusik, sp. nov. (♂♀; UAE) (Lycosidae), and Prodidomus emiratus Zamani & Marusik, sp. nov. (♀; UAE) (Prodidomidae). In addition, the previously unknown male of Trichothyse golan (Levy, 1999) (Gnaphosidae) is illustrated and described. Finally, one new family record, 16 new generic records and 22 new species records are documented, and the previous record of Sahastata infuscata (Kulczyński, 1901) (Filistatidae) from Yemen is rejected.
