When Tarantula Venom Comes from a Misnamed Spider: The Importance of Taxonomic Accuracy in Theraphosid Toxinology

  When Tarantula Venom Comes from a Misnamed Spider: The Importance of Taxonomic Accuracy in Theraphosid Toxinology I am very happy to share my most recent publication in Toxicon. This is a particularly meaningful publication for me because it brings together two areas that have become an important part of my work and personal interests: tarantulas and toxinology. At first glance, taxonomy and venom research may seem like two very different fields. In reality, they are closely connected. Before we can properly study the venom of a spider, we need to know which spider we are actually studying. Why the Name Matters A scientific name is much more than a label attached to an animal. It connects that animal to everything we report about it, including its biology, distribution, behavior, venom, toxins, and even its potential medical importance. When a tarantula is incorrectly identified, or when an outdated name continues to be used without considering changes in taxonomy, the problem ca...

Examining ecological niche for six species of whip spider in Colombia 

Abstract

The conditioning variables for the establishment of Amblypygi populations and their ecological interactions are currently poorly studied. Delving deeper into this can help to conserve this group of short-range distribution species, which are useful as a model in biogeographic research. In this study, we evaluated the distribution and overlapping patterns of ecological niche in six species of amblypygids (Phrynus araya, P. panche, P. pulchripes, Heterophrynus batesii, H. boterorum, H. cervinus) in the Andean and Amazonian ecosystems of Colombia, revealing a clear biogeographic segregation driven by environmental gradients: Phrynus species were associated with inter-Andean valleys with high thermal and water seasonality.  While the Heterophrynus occupied more stable and humid conditions of foothills and middle elevations. Overlap analyses showed significant divergence (e.g., D=0.105 between P. panche and H. batesii), with high unfilling values (up to 73.2%), indicating limited niche overlap and habitat specialization, although historical coexistence was detected in certain pairs of species (e.g., 99.1% stability between H. cervinus and H. boterorum). In the future, the integration of ecological niche modeling (ENM) with phylogeographic and behavioral approaches will be crucial for identifying niche partitioning mechanisms and optimizing conservation strategies for endemic taxa in complex tropical landscapes.
