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...

Invertebrates of AlUla: Scorpions, Spiders, Dragonflies and Butterflies (Field Guide)

Dear Arachnologist Friends,

It’s my pleasure to share that a field guide I co-authored—“Invertebrates of AlUla: Scorpions, Spiders, Dragonflies and Butterflies” (part of the Fauna of AlUla Field Guide Series)—has been made freely available in PDF format by the Royal Commission for AlUla (RCU).

The guide is available in both English and Arabic, with the aim of reaching a broad audience.
You’ll also find many other publications and field guides from different disciplines available at the same link.

While some taxonomic updates are already underway—particularly for the scorpions—this guide currently represents the most comprehensive and up-to-date resource for this historically important, yet previously understudied, region of the Arabian Peninsula.

The beautiful illustrations throughout the series were created by the talented Davina Falcão, who brought all the featured animals to life with her art. If interested, I leave here her website to appreciate her art! https://davinafalcaoart.com.

We warmly welcome any feedback or suggestions—and if you're interested in collaborating, there's still a lot of potential to build on this work. For that you can reach me at the email address yurisimone1@gmail.com.

A huge collective hug and see you in Croatia!
