The family Skeneidae, originally characterized by their minute size, lack of nacre and a rhipidoglossate radula, is an example of a polyphyletic assemblage. Most ‘skeneimorph’ species are based on the shell, sometimes the radula and rarely featur

We recently reported the birth of a tammar wallaby produced by intrauterine AI [Paris DBBP et al., Australian Mammal Society Conference, July 2002]. The use of AI has great potential for the conservation of rare and endangered marsupials, but a non-s

We developed a method of using external morphological characteristics to determine the sex of yellow perch Perca flavescens. The characteristics used were (1) the shape of the urogenital opening, (2) the shape of the anterior edge of the urogenital o

Males of the viviparous teleost fish Gambusia affinis copulate with females by using a specialized anal fin, or gonopodium. When female G. affinis were placed in a shallow transparent tank which was then floated on the surface of a larger aquarium ho

Bone morphogenetic protein (Bmp) signaling has long been known to be important for the early development of the ventral mesoderm, including blood,vasculature and kidney cells. Although Bmp genes are continually expressed in the ventral cells througho

Due to the variability in vaginal anatomy among marsupials, the female reproductive tract must be examined for each species prior to developing artificial insemination using catheters. The grey short-tailed opossum (Monodelphis domestica) is a nonsea
