Reproductive biology of the pampas deer (Ozotoceros bezoarticus): a review  

Microsoft Academic Search

The pampas deer (Ozotoceros bezoarticus) is a South American grazing deer which is in extreme danger of extinction. Very little is known about the biology of the pampas deer. Moreover, most information has not been published in peer-reviewed scientific journals, and is only available in local publications, theses, etc. Therefore, our aim was to update and summarize the available information

Reproductive biology of the pampas deer (Ozotoceros bezoarticus): a review  

PubMed Central

The pampas deer (Ozotoceros bezoarticus) is a South American grazing deer which is in extreme danger of extinction. Very little is known about the biology of the pampas deer. Moreover, most information has not been published in peer-reviewed scientific journals, and is only available in local publications, theses, etc. Therefore, our aim was to update and summarize the available information regarding the reproductive biology of the pampas deer. Moreover, in most sections, we have also included new, unpublished information. Detailed descriptions are provided of the anatomy of both the female and the male reproductive tract, puberty onset, the oestrous cycle and gestational length. Birthing and the early postpartum period are described, as are maternal behaviour and early fawn development, seasonal distribution of births, seasonal changes in male reproduction and antler cycle, reproductive behaviour, semen collection, and cryopreservation. Finally, an overview is given and future directions of research are proposed.

Effect of cattle breeding on habitat use of Pampas deer Ozotoceros bezoarticus celer in semiarid grasslands of San Luis, Argentina  

Microsoft Academic Search

The largest population of the Argentinean Pampas deer Ozotoceros bezoarticus celer is found in the semiarid grasslands of the San Luis province. Despite relatively high deer numbers in the region, there has been concern that expansion of farming practices could displace the species. Since the 1990’s, cattle breeding has intensified especially as a result of the replacement of natural grassland

Seasonality of the antler cycle of pampas deer (ozotoceros bezoarticus leucogaster) from the pantanal wetland, brazil  

Microsoft Academic Search

Antler cycle of tropical deer species is little known, in contrast to cervids of temperate zones. Since the antler cycle is controlled by the photoperiod and the consequent pattern of hormone secretion, temperate?zone cervids show a seasonal antler cycle. For tropical deer, the seasonality is not well defined or is unknown for many species. This study reports monthly observations of

Anatomical and scanning electron microscopic characteristics of the tongue in the pampas deer (Cervidae: Ozotoceros bezoarticus, Linnaeus 1758).  

PubMed

This study represents the first definitive anatomical description of the tongue and lingual papillae of the pampas deer and compares the different information on the morphology of the other ruminant species available in the literature. In this study, the tongues of four adult and one fetal deer were used. The tongue was elongated with an oval or rounded apex. The filiform papillae on the lingual apex were smaller than the ones on the dorsal and lateral surfaces of the lingual body. Two very thin secondary papillary projections were found to emerge from the bilateral sides of some filiform papillae. Spherical fungiform papillae were randomly distributed among filiform papillae on dorsal surface of the lingual body and ventral surface of the apex. More developed conical papillae were observed in the caudal half of the lingual torus, whereas the rostral half of the torus had smaller conical papillae. Each conical papilla included shallow longitudinal groove on its anterior surface and some conical papillae on the lingual torus had bifid sharp apices. On the caudal portion of the torus, we also observed a few fungiform papillae, which were larger than those located on the lingual body. There were no lenticular papillae on the lingual torus, and five to nine round or oval circumvallate papillae were situated on each caudolateral side of the lingual torus. Morphological features of the tongue in the pampas deer were more similar to wild ruminant species than they were to domestic species. Microsc. Res.
