Divergence and reticulation among montane populations of a jumping spider (Habronattus pugillis Griswold).
Populations of the jumping spider Habronattus pugillis Griswold isolated on nearby mountain ranges in southern Arizona are differentiated in many features of the males (color, shape, and orientation of setae on face; shape of carapace; markings of palpi and legs; motions during courtship behavior). These features are (mostly) consistent within a range and different between ranges. The concentra...
متن کاملREGIONAL SEISMIC SONG DIFFERENCES IN SKY ISLAND POPULATIONS OF THE JUMPING SPIDER <i>HABRONATTUS PUGILLIS</i> GRISWOLD (ARANEAE, SALTICIDAE)
Jumping spiders have long been used as model organisms to study visual communication. However, recent studies documenting the presence of intricate multicomponent seismic songs during courtship displays suggest an important role of seismic communication as well. Given the relatively recent focus on seismic communication, the extent to which seismic songs vary among jumping spider species or eve...
متن کاملPhylogeography of the jumping spider Habronattus pugillis (araneae: salticidae): recent vicariance of sky island populations?
In island systems with diverging populations, the history of island formation and genealogical estimates of divergence dates can be mutually informative. In the "sky islands" of southeastern Arizona, climate-induced contraction of woodlands appears to have fragmented populations of woodland-dwelling species onto disjunct mountain ranges. Montane populations of the jumping spider, Habronattus pu...
متن کاملTwo new jumping spider species of the Habronattus clypeatus group (Araneae, Salticidae, Harmochirina)
Two species of the Habronattus clypeatus species group are described, Habronattus arcalorussp. n. from Texas and Colorado, and Habronattus gilaensissp. n. from New Mexico. Habronattus arcalorus males have extravagant ornamentation: a green first leg with an unusually dense lateral fringe of orange and white hairs, and a large grey triangular patella on the third leg with blue-white scales nearb...
متن کاملSexual selection driving diversification in jumping spiders.
Theory predicts that speciation rates should be accelerated in organisms undergoing sexual selection. In systems involving female choice, sexual selection acts directly on traits that may be important in prezygotic reproductive isolation, potentially fostering rapid divergence of such traits among allopatric populations. Despite the appeal of this concept, it has proven difficult to document. W...
