An Integrative Approach. Author: Rui F. Oliveira,Michael Taborsky,H. Jane Brockmann; Publisher: Cambridge University Press ISBN: Category: Medical Page: N.A View: DOWNLOAD NOW» The study of alternative reproductive tactics (the behavioural strategies used by individuals to increase their reproductive success) is an evolutionary puzzle, and one of great interest to researchers. Which vertebrates use each type of reproductive strategy? refers to the development of an embryo inside an egg within the mother's body until it hatches. The mother provides no nourishment to the developing embryo inside the egg. This occurs in some species of fish and reptiles.

W. Saltzman, in Encyclopedia of Animal Behavior, Hormonal Mechanisms of Reproductive Skew in Noncooperative Breeding Systems. Although reproductive skew is most pronounced in cooperatively breeding and eusocial species, moderate asymmetries in the distribution of direct reproduction within social groups may occur in other types of vertebrate breeding systems.   In this live Grade 12 Life Sciences show we take a look at Reproduction in Vertebrates. In this lesson we review the schematic outline of the human life cycle to show the role of meiosis, mitosis.

This series of volumes represents a comprehensive and integrated treatment of reproduction in vertebrates from fishes of all sorts through mammals. It is designed to provide a readable, coordinated description of reproductive basics in each group of vertebrates as well as an introduction to the latest trends in reproductive research and our Brand: Elsevier Science. This volume is intended to draw attention to these pressing matters by gathering a wide representation of scientists actively engaged in reproduction research relating to South American vertebrates. It is intended that this volume will serve as a re­ source for individuals and organizations interested in reproductive biology and species survival.

Skew theory investigates the genetic and ecological factors causal to the partitioning of reproduction in animal groups and may yield fundamental insights into the evolution of animal sociality.

This book brings together new theory and empirical work, mostly in vertebrates, to Format: Hardcover. This book brings together new theory and empirical work, mostly in vertebrates, to test assumptions and predictions of skew models.

It also gives an updated critical review of skew theory. The team of leading contributors cover a wide range of species, from insects to humans, and discuss both ultimate (evolutionary) and proximate (immediate.
