    Dieta estacional del Tayassu pecari (Artiodactyla: Tayassuidae) en el Parque Nacional Corcovado, Costa Rica
    (Universidad Nacional, Costa Rica., 2000) Altrichter, Mariana; Sáenz, Joel C.; Eduardo, Carrillo; Fuller, Todd
    The diet of the white-lipped peccari Tayassu pecari was studied from July 1996 to April 1997 in Cor covado National Park, Costa Rica, through fecal analysis and direct observations. The feces consisted of 61.6% fruits, 37.5% vegetative parts, 0.4% invertebrates and 0.5% unidentified material. These proportions are similar to those reported for white-lipped peccaries diet in South America, but the species consumed were different. In Corcovado, the white-lipped peccary fed on parts of 57 plant species (37 of them fruits). Moraceae was the most represented farnily. In contrast, the diet of the Peruvian Amazon peccary primarily consists of plant parts (Are caceae). Costa Rican peccary diet consisted of vegetative parts from Araceae and Heliconaceae. Direct observa tion showed that peccaries spent 30% of feeding time rooting. Samples taken from rooting sites suggest that pec caries fed on earthworrns. Diet differed between months, seasons and habitats. They ate more fruits in coastal and primary forests and more vegetative parts in secondary foresto In the months Octubrer and November the consumption oC vegetative parts excéeded fruit consumption

    Exploitation of white-lipped peccaries Tayassu pecari (Artiodactyla: Tayassuidae) on the Osa Peninsula, Costa Rica
    (Universidad Nacional, Costa Rica., 2002) Altrichter, Mariana; Almeida, Roberval
    We studied movements of white-lipped peccaries (Tayassu pecari, Artiodactyla, Tayassuidae) throughout the Osa Peninsula and their use by local people during 1997-2000, using interview techniques. We draw five main conclusions: 1) White-lipped peccaries living on the Osa Peninsula range within Corcovado National Park for most of the year. 2) Peccaries travel beyond the Park boundaries to the north and south-east of the Peninsula at the end of the wet season when a fruit shortage occurs in Corcovado. 3) The local people hunt peccaries as the herds move through the Peninsula. 4) Current small herd sizes observed by locals in the Peninsula and by researchers in the Park may indicate a decline of the peccary population. 5) Peccaries constitute neither an important source of food nor a source of cash income for local people. We suggest that sustainable use of peccaries in this region is neither realistic nor necessary. Instead of trying to legalize and regulate hunting, effective systems to control illegal hunting should be implemented, especially outside the Park boundary from October to January when the animals are on the move. © 2002 FFI.
