Most conventional spermatology research involves common mammalian species including livestock, laboratory animals and humans. Yet, there are more than 4500 mammalian species inhabiting the planet for which little is known about basic reproductive biology, including sperm characteristics and function. This information is important, not just as adjunct knowledge, but because the majority of these species are threatened with extinction, largely due to human-induced pressures. The field of… 

Role of reproductive technologies and genetic resource banks in animal conservation.

The potential contribution of reproductive biology and genetic resource banks to animal conservation is identified, but the complexity of issues determining the extent to which this potential can be achieved is highlighted.

Approaches and efficacy of artificial insemination in felids and mustelids.

Assisted reproduction for managing and conserving threatened felids

An overview of some of the species-specific breeding traits that have been discovered while developing assisted reproduction techniques for felids and how this new knowledge can be applied to improve breeding and management is provided.

Reproductive Science and Integrated Conservation: Contents

This compendium of papers from world experts makes a start at redressing the authors' ignorance on reproductive science in all its multiple sub-disciplines.

ASSESSMENT OF MALE GIANT PANDA SEASONAL REPRODUCTION, SEXUAL MATURITY AND COMPARATIVE SPERM CRYOTOLERANCE

Evidence is provided that reproductive seasonality in the male giant panda is more protracted than the female, with coordinated increases in testes size, androgen production, sperm density, and sexual behaviors; thereby maintaining reproductive competence to prepare for, and accommodate, a brief unpredictable female estrus.

Reproductive status of endemic felid species in Latin American zoos and implications for ex situ conservation

Breeding success and reproductive traits for many endemic felids in Latin American zoos appear to be suboptimal, and likely would benefit from improvements in diet and exhibitry.

Genetic Resource Banks and Reproductive Technology for Wildlife Conservation

Cryobiology, or low temperature biology, dictates the authors' ability to successfully store animal germ-plasm, tissues and DNA which will be vital to managing both species and genetic variation.

Reproductive and genetic consequences of founding isolated lion populations

In an examination of three distinct lion populations, a direct correlation was observed between genetic variability and two physiological traits, incidence of abnormal sperm and circulating testosterone, a critical hormone for spermatogenesis.

Rescue and maturation in vitro of follicular oocytes collected from nondomestic felid species.

It is demonstrated that immature ovarian oocytes from rare felid species can be stimulated to mature in vitro despite an excision-to-culture interval as long as 36 h and matured to metaphase II in vitro.

Analytical DNA fingerprinting in lions: parentage, genetic diversity, and kinship.

The results suggest that reliable estimates of relative genetic diversity, of parentage, and of individual relatedness can be achieved in free-ranging populations, provided the minisatellite family is calibrated in established pedigrees for the species.

Reproductive physiology of the clouded leopard: I. Electroejaculates contain high proportions of pleiomorphic spermatozoa throughout the year.

The data suggest that a physiological asymmetry may exist in peak reproductive performance between the male and female clouded leopard, perhaps as a result of differing adaptations to the captive environment.

The Diversity of Life

In this book a master scientist tells the story of how life on earth evolved. Edward O. Wilson eloquently describes how the species of the world became diverse and why that diversity is threatened

Function and culture requirements of snow leopard (Panthera uncia) spermatozoa in vitro.

Electroejaculates from eight snow leopards were used to determine how the motility of spermatozoa was influenced by type of media (Ham's F10, PBS, human tubal fluid or RPMI-1640) and a sperm metabolic enhancer, pentoxifylline.

REPRODUCTIVE CHARACTERISTICS OF MALE FLORIDA PANTHERS: COMPARATIVE STUDIES FROM FLORIDA, TEXAS, COLORADO, LATIN AMERICA, AND NORTH AMERICAN ZOOS

Type A Florida panthers had the lowest testicular volume and sperm-motility ratings and were the only animals exhibiting unilateral cryptorchidism, demonstrating the existence of major morphological and physiological differences among populations of F. concolor , a finding potentially related to differences in genetic diversity.
