Reproductive Biology ad Phylogeny of Lizards and Tuatara

Reproductive Biology and Phylogeny of Lizards and Tuatara PDF

By Justin L. Rheubert, Dustin S. Siegel and Stanley E. Trauth

Reproductive Biology and Phylogeny of Lizards and Tuatara PDF is a remarkable compendium of chapters written by the world’s leading experts from over four continents. The book begins with a chapter recounting historical discoveries in reproductive biology and a review of phylogenetics and up-to-date hypotheses concerning evolutionary relationships among lizards.

Following these chapters are detailed reviews with additional new data concerning chemical communication, sexual selection, reproductive cues, female reproductive anatomy, female reproductive cycles, oogenesis, parthenogenesis, male reproductive anatomy, male reproductive cycles, spermatogenesis, reproductive investment, viviparity and placentation, multiple paternity, and parental care.

The book culminates in two chapters on tuatara reproduction giving unique insight into evolutionary patterns in reproductive biology in squamates and tuatara. This is an essential resource for anyone studying reproduction in reptiles and/or vertebrates and offers a fascinating read for those interested in reproductive biology.
