Estudo de uma população relictual de veado-campeiro, Ozotoceros bezoarticus (Linnaeus) (Artiodactyla, Cervidae) no municipio da Lapa, Paraná, Brasil

A relictual population study of pampas deer, Ozotoceros bezoarticus (Linnaeus) (Artiodactyla, Cervidae) at Lapa, Paraná State, Brazil

Resumo

The pampas deer, Ozotoceros bezoarticus (Linnaeus, 1758) was studied between August 1996 and September 1997 at Fazenda Santa Maria (25º34' and 25º36'S, 49º46'and 49º49'W) at Lapa, Paraná State. During that period we have collected information on feeding habits, group composition, time of the year for birth of youngsters and time for antlers change. The presence of the animal in the area was confirmed by the finding of vestiges and visual occurrences. Animais were observed feeding on young leaves of soya been (Glicine max), oat (Avenasaliva), ryegrass (Lolium mulliflorum) and barley (Hordeum vulgare). Only one female was observed feeding on dry leaves. A stag was observed feeding on a barley ear. Group's average size was 1.5 individual. Stags/female proportion was 1: 0.96. Animais displaying velvet coated antlers were observed in June and July which is in accordance with literature about antlers change in a definite period restricted to winter. Only one youngster was observed in September 1996. It is believed that the species survive in the region despite human activities through adaptation of feeding habits with the introduction of agricultura! species. This population could disappear in a few years because of the small number of individuais and their isolation.
