Abstract |
Modern felid species descend from relatively recent (<11 million years ago) divergence and
speciation events that produced successful predatory carnivores worldwide but that have
confounded taxonomic classifications. A highly resolved molecular phylogeny with divergence dates
for all living cat species, derived from autosomal, X-linked, Y-linked, and mitochondrial gene
segments (22,789 base pairs) and 16 fossil calibrations define eight principal lineages produced
through at least 10 intercontinental migrations facilitated by sea-level fluctuations. A ghost lineage
analysis indicates that available felid fossils underestimate (i.e., unrepresented basal branch
length) first occurrence by an average of 76%, revealing a low representation of felid lineages
in paleontological remains. The phylogenetic performance of distinct gene classes showed that
Y-chromosome segments are appreciably more informative than mitochondrial DNA, X-linked,
or autosomal genes in resolving the rapid Felidae species radiation. |

Abstract |
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 conservation is changing rapidly, and global cooperation is emerging among a variety of wildlife enthusiasts, ranging from management authorities of nature reserves to curators of rare zoological collections. Conservation progress depends on systematic, multidisciplinary research first to answer basic questions, with new data then applied to endangered species management plans. The reproductive physiologist is a crucial component of this scheme. Reproduction is the essence of species survival, and enormous effort needs to be directed at these 'untraditional' research species, subspecies and populations. Spermatology research combined with simultaneous efforts in endocrinology, embryology and cryopreservation (among others) can lead to the successful application of assisted reproduction. Examples from this laboratory include an array of wild felid species and a rare cervid and mustelid. Obstacles to success are formidable, including unique species-specificities, diminished genetic diversity and a general lack of resources. Nonetheless, the field offers tremendous opportunities for generating unique knowledge of comparative interest and with conservation utility. |

Abstract |
The snow leopard (Uncia uncia) is a rare carnivore living above the snow line in central Asia. Using universal primers for the mitochondrial genome control region hypervariable
region 1 (HVR1), we isolated a 411-bp fragment of HVR1 and then designed specific primers
near each end of this sequence in the conserved regions. These primers were shown to yield
good polymerase chain reaction products and to be species specific. Of the 12 snow leopards
studied, there were 11 segregating sites and six haplotypes. An identification case of snow
leopard carcass (confiscated by the police) proved the primers to be a useful tool for forensic
diagnosis in field and population genetics studies. |
