Insights Into Spatial Orientation and Cognition in Tarantulas (Araneae: Theraphosidae) Under Natural Conditions, With Notes on Possible Ontogenetic Niche Shifts

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Cognitive studies on spiders have largely ignored mygalomorphs, such as tarantulas, and almost completely lack field‐based observations. We present nine observations of arboreal and fossorial New World tarantulas, including a blind cave‐dwelling species, providing evidence for possible experience‐based navigation and spatial learning during foraging ...

Arthropod Assemblages in Desert Ecosystems of Alula County, Saudi Arabia

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This study provides preliminary descriptions of arthropod communities in two desert habitats—arid thorn woodlands and wadis—across protected areas in AlUla County, in the Kingdom of Saudi Arabia. Pitfall trapping over a 6‐day period yielded more than 2000 specimens representing at least 189 morphospecies, with ants (Formicidae) and springtails ...

Tell Me How Much DNA You Have and I'll Tell You What Your Sex Is: Sex Determination by Flow Cytometry of Spiderlings of Allocosa marindia

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
The manuscript addresses the sex determination of spiderlings of the wolf spider Allocosa marindia using flow cytometry. Spiders are born with a defined sex, but it is not possible to determine their sex phenotypically until the adult or near‐adult stage. Sex identification at early stages of development is of great interest for studies in evolutionary
