(Biology, 2009-09-16)
Theraphosids, commonly known as “tarantulas”, are a group of large, hirsute spiders that have drawn relatively little interest in ecological, behavioral, or evolutionary research from biologists. The lack of research on ...
Sequence Evolution Of Recurrently Recruited Retroposed Genes In Drosophila And Their Possible Role In Meiotic Drive
(Biology, 2009-09-16)
Gene duplications are a valuable source of genetic information that can evolve under positive selection creating a new gene function without affecting the original function.A gene duplication mechanism is retroposition. ...

Ecomorphology Of The Mexican Fence Lizards Of The Sceloporus Formosus Group (Squamata: Phrynosomatidae)
(Biology, 2009-09-16)
A central belief of ecomorphological studies is the link between morphology and performance, but, surprisingly few analyses demonstrate this relationship. Fence lizards of the genus Sceloporus offer a useful system for ...
