Diversidade de morcegos em Palmeira do Piauí, nordeste do Brasil

Abstract

The city of Palmeira of Piauí, Piauí located in the Southwest region of the state is marked by the presence of mountains in its surroundings, concentrating large areas characterized as valleys, used by citizens for cattle breeding. In the valley known as bat slack, bat attacks on reses are very common causing them to get lost due to infections and may even come to death. This condition caught the attention of the creators who, in addition to bittering losses, began to fear for their lives and their families. The bjective of the research in the municipality of Palmeira of Piauí was to clarify the reasons why attacks by vampire bats in this community are so frequent and to differentiate the morphological type characteristic of vampire bats in the medium non hematophagous chiroptera. For this, 4 collections were carried out during the period from August 2019 to January 2020 chosen based on the lunar calendar, mist nets are being set up around the corrals when the animals are contained during the night, two in the rainy season and two in the dry season. In the nets were visualized 14 species of bats of different trophic guilds, 17 hematophagous bats of the species Desmodus rotundus were captured. The captured animals were shown to the breeders and photographed for later identification in the local Community pointing out morphological characterization and differentiating hematophagous and non-hematophagous, extolling the importance of the variety of bat species for the maintenance of ecosystem synergy. The vegetation change for grass planting associated with changes in the interest of cattle breeding helps explain the incidence of attacks. This practice helped the dissemination of reports through oral communication and presentation of papers in scientific events This practice helped the dissemination of reports through oral communication and presentation of papers in scientific events contributing to the reduction of the widespread extermination of these animals.
