Examining ecological niche for six species of whip spider in Colombia

  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 b...

Abstract

Background

The genus Eresus Walckenaer, 1805, commonly known as the ladybird spiders, comprises 30 species primarily distributed in the Palaearctic, Afrotropical and Oriental Regions as well as South America, with only one species, E. kollari Rossi, 1846, recorded from South Korea.

New information

New taxonomic and distribution data on the genus Eresus Walckenaer, 1805, are provided. A newly-recorded species, E. granosus Simon, 1895, is described along with E. kollari Rossi, 1846 with a detailed description, illustrations and ecological photographs from South Korea.
