Karyotypes of Three Spider Species
Australian spiders of the genus Abstract. -Three species of the spider genus Physocyclus (P. calijbrnicus, P. enaulus. P, sp.) . SOC. 96:359-362. were karyotyped using an air-drying, Giemsa staining method. All chromosomes were metacentric, with males being 2n = 15 (N = 7 + XO) and females being 2n = 16. The karyotyping method resulted in slide preparations which were countable five years post-...
متن کاملFunctional morphology of extreme jaw protrusion in Neotropical cichlids.
The New World cichlids Petenia splendida and Caquetaia spp. possess extraordinarily protrusible jaws. We investigated the feeding behavior of extreme (here defined as greater than 30% head length) and modest jaw-protruding Neotropical cichlids by comparing feeding kinematics, cranial morphology, and feeding performance. Digital high-speed video (500 fps) of P. splendida, C. spectabile, and Astr...
