  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...

The genome sequence of the house spider, Eratigena atrica (C.L.Koch, 1843) (Araneae: Agelenidae)

Abstract

We present a genome assembly from a male specimen of Eratigena atrica (house spider; Arthropoda; Arachnida; Araneae; Agelenidae). The genome sequence has a total length of 4 947.42 megabases. Most of the assembly (98.73%) is scaffolded into 22 chromosomal pseudomolecules, including the X1 and X2 sex chromosomes. The mitochondrial genome was also assembled, with a length of 14.25 kilobases.
