Abstract(s)
Em Portugal, o Coelho-Bravo (Oryctolagus cuniculus algirus) e a Lebre-Ibérica (Lepus granatensis) são espécies muito importantes dentro dos ecossistemas. Desempenham um papel fundamental na cadeia alimentar de predadores com estatuto de espécie rara ou em perigo de extinção como é o caso do Lince-Ibérico (Lynx pardinus). Ambas as espécies têm elevado valor económico, uma vez que são bastante procuradas pelos caçadores. No entanto, nas últimas décadas têm vindo a sofrer uma preocupante diminuição nas suas populações. Esta diminuição relaciona-se diretamente com o aparecimento de epizootias, fragmentação do habitat, predação, pressão cinegética excessiva e a intensificação da agricultura. O presente estudo foi efetuado entre Janeiro e Setembro de 2012, incidiu na influência que a alimentação tem para com a reprodução, num cercado onde coexistem ambas as espécies de lagomorfos. Os resultados deste trabalho revelaram que na área de estudo o coelho não apresenta pausa reprodutora no verão, provavelmente devido ao consumo de plantas hortícolas evidenciado pelo estudo do regime alimentar, durante o período estival. Pretendeu-se dar a conhecer o comportamento alimentar e reprodutivo do coelho-bravo e da lebre, regimes alimentares essenciais para a estratégia reprodutora e principalmente concentrar um conjunto de informações de elevada utilidade na gestão de zonas de caça e na tomada de decisões a fim de preservar as espécies.
In Portugal the Wild Rabbit (Oryctolagus cuniculus algirus) and Iberian Hare (Lepus granatensis) are very important species in ecosystems. They play a key role in the food chain, mainly for predators with the status of rare species or endangered species such as the Iberian Lynx (Lynx pardinus). Both species have high economic value because are quite sought by hunters. However, in recent decades both species have been suffering an worrying decline in their populations. This decrease relates directly to the emergence of animal diseases, habitat fragmentation, predation, hunting pressure and excessive intensification of agriculture. The present study was conducted between January and September 2012, focused on the influence of feeding importance to reproduction strategy, in a pen where both species coexist. The results of this study revealed that the rabbit hasn’t register of pause on reproduction in summer, probably due to consumption of vegetable plants evidenced by the diet during the summer period in this study. We intend to show reproductive and feeding behavior of wild rabbit and hare diets essential for reproductive strategy, and focus mainly a collection of information of high utility in the management of hunting areas and in making decisions in order to preserve the species.
