Herpetofauna (anfíbios e répteis) da estação ecológica Maracá – Jipioca, Amapá, Brasil

Abstract

In relation to the Guiana shield, the state of Amapá is highlighted as the region with the higher richness of species of herpetofauna, however, there is a gap in knowledge, when compared to the number of species existing in the Amapá territory. The fauna surveys allow the knowledge of the richness of species present in a determined region, being fundamental for future conservation strategies. In this context, this work aimed to carry out a survey of the herpetofauna of the Estação Ecológica de Maracá-Jipioca, in order to obtain pertinent information to complement the management plan, as well as to measure the richness of this fauna group aiming at its conservation. The present study was carried out at the Ecological Station of Maracá-Jipioca, located in the northern channel of the state of Amapá, from April 2019 to February 2020, with field work carried out every three months, during five days each, through different capture methodologies. A total of 210 individuals of 29 species (9 amphibians and 20 reptiles) were registered at the Ecological Station of Maracá-Jipioca. For anurans, the family Hylidae (6 species) was the most representative, with the higher number of species, and for reptiles, was the family Teiidae (4 species). The active and auditory search proved to be the most efficient method, being responsible for 78.2% of the captured individuals. The use of different capture methodologies proved to be effective, as well as in several other surveys of herpetofauna. This work provides data that seeks to fill part of the existing gaps in relation to the herpetofauna of the state of Amapá and assists in the conservation of species.
