Reproductive Biology and Phylogeny of Gymnophiona (Caecilians)

Jean-Marie EXBRAYAT, 2006

Couverture du livre d'Exbrayat reproductive biology


The Gymnophiona is the third amphibian order, Anura and Urodela being the two others, and contains some 154 species belonging to 34 genera and 6 families. This book devoted to reproductive biology and phylogeny of Gymnophiona begins with a chapter on the history of research in this groups. The second chapter concerning the phylogeny of Gymnophiona with systematics, gives the most recent classification of these species with a useful diagnosis. Other chapters deal with general observations on anatomy, physiology, with special references to male and femal urogenital systems ; the Mullerian gland in Uraeotyphlus narayani ; endocrinology of reproduction in both males and females ; spermatogenesis ; the structure of spermatozoa with phylogenetic conclusions ; oogenesis and folliculogenesis ; embryonic development of genital glands, a neglected aspect of caecilian anatomy : parity ; and the peculiar cas of viviparity in Typhlonectes compressicauda.
