Embryogenesis in conservation biology - or, how to make an endangered species embryo
125
TL;DR: Embryo technologies have not as yet contributed to practical conservation of rare wildlife species, but if reality-based conservation is defined as a continual data-gathering process that assimilates any and all information ultimately useful for preserving species, then embryo technologies are making considerable contributions to conservation biology.

Current achievements and future research directions in ovarian tissue culture, in vitro follicle development and transplantation: implications for fertility preservation
Johan Smitz,Marie-Madeleine Dolmans,Jacques Donnez,J.e. Fortune,Outi Hovatta,K. Jewgenow,Helen-Mary Picton,Carlos E. Plancha,Lonnie D. Shea,Richard L. Stouffer,Evelyn E. Telfer,Teresa K. Woodruff,Mary B. Zelinski +12 more
TL;DR: Experiments on ovarian tissue from non-human primate models and from consenting fertile and infertile patients benefit from a multidisciplinary approach.
Embryo technology in conservation efforts for endangered felids.
TL;DR: The domestic cat is not only a valuable model for development of in vitro techniques but may serve as a recipient of embryos from several species of small wild cats.

Reproductive characteristics of male florida panthers: comparative studies from florida, texas, colorado, latin america, and north american zoos
Mark A. Barone,Melody E. Roelke,JoGayle Howard,Janine L. Brown,Allen E. Anderson,David E. Wildt +5 more
TL;DR: 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.

The effect of Equex STM paste and sperm morphology on post-thaw survival of cat epididymal spermatozoa.
TL;DR: Results clearly show that addition of Equex STM paste in the freezing extender protects the acrosomes of cat epididymal spermatozoa during the freezing--thawing process, but reduces the sperm longevity during in vitro incubation at 38 degrees C.

Heterologous in vitro fertilization and sperm capacitation in an endangered African antelope, the scimitar-horned oryx (Oryx dammah).
TL;DR: Capacitation can be induced using cattle sperm-processing techniques, with sperm appearing most responsive to elevated CaCl concentrations, and the successful production and development of hybrid embryos after coincubation of oryx sperm with cow oocytes, suggesting that the two bovid species have similar fertilization mechanisms.

Genetic basis for species vulnerability in the Cheetah
Stephen J. O'Brien,Melody E. Roelke,Laurie Marker,Amy Hauck Newman,Cheryl A. Winkler,D. G. Meltzer,L. Colly,James F. Evermann,Mitchell Bush,David E. Wildt +9 more
TL;DR: The extreme genetic monomorphism, especially at the major histocompatibility complex, and the apparent hypersensitivity of the cheetah to a viral pathogen may be related, provide a biological basis for understanding the adaptive significance of abundant genetic variation in outbred mammalian species.

Inbreeding and juvenile mortality in small populations of ungulates
TL;DR: Juvenile mortality of inbred young was higher than that of noninbred young in 15 of 16 species of captive ungulates.

TL;DR: Results indicate that seminal characteristics in the cheetah are markedly inferior compared to the domestic cat, particularly with respect to the incidence of pleiomorphic spermatozoa.

Tigers of the world : the biology, biopolitics, management, and conservation of an endangered species
Ronald Lewis Tilson,Ulysses S. Seal +1 more

TL;DR: In this article, 40 world authorities on tigers from Asia, Europe, and North America have summarized and identified the management, conservation, and research needs for this endangered species, including the white tiger.

Developmental competence of domestic cat follicular oocytes after fertilization in vitro.
TL;DR: Follicles subjected to aspiration appear capable of forming normal, functional CL and the birth of live young after embryo transfer unequivocally demonstrates the developmental competence of in vitro-fertilized carnivore oocytes.
