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...

ERGA-BGE-CBP chromosome-level genome assembly of the blind scorpion Belisarius xambeui Simon, 1879 (Belisariidae, Scorpiones), the most singular scorpion in Europe

Abstract

We present a chromosome-level reference genome for the blind scorpion Belisarius xambeui Simon, 1879 (Belisariidae, Scorpiones). The genome size estimated by flow cytometry (4.32 Gb) closely matches the final assembly size (3.98 Gb). The final assembly comprises 19,045 scaffolds, including 56 chromosome-level scaffolds (pseudochromosomes) that account for 90.08% of the total assembly. Nucleotide diversity across the genome was low, with an average π of 0.0018.
