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...

A trial study on the spider diversity (Araneae species) in Agartala City of West Tripura district in Tripura, India

Abstract

This study reported the diversity of spiders in Agartala city of West Tripura district in Tripura, India. A total of 9 families, 14 genera and 16 species were recorded. The most abundant family was found Araneidae (25%), followed by Salticidae (18.5%), Sparassidae and Nephilidae (12.5%), and Sicariidae, Pholcidae, Therididae, Tetragnathidae, and Thomisidae presented similar percentage of abundance (6.25%) in this study. This study exclusively reports for the first time the presence of the Sicariidae family in Tripura, along with morphological characters and behaviours, like web-building structure and activity time, were also analyzed for the spiders collected in this study.
