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

  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...

The genome sequence of a running crab spider, Tibellus oblongus (Walckenaer, 1802) (Araneae: Philodromidae)

Abstract

We present a genome assembly from an individual female Tibellus oblongus (running crab spider; Arthropoda; Arachnida; Araneae; Philodromidae). The assembly contains two haplotypes with total lengths of 3 189.47 megabases and 3 294.81 megabases. Of haplotype 1 and haplotype 2, 99.03% and 91.65% of the sequence, respectively, are scaffolded into 13 chromosomal pseudomolecules, including X1 and X2. The mitochondrial genome has also been assembled, with a length of 14.37 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.
