Índice de crescimento corporal de Pithecopus nordestinus caramashi, 2006 (Phyllomedusidae, Anura) em um fragmento de mata atlântica, no Nordeste do Brasil.

Abstract

Anurans are the most diverse amphibian group in the world, and 6,671 species are currently known, of which about 1,000 occur in Brazil. The reproductive cycle of the frogs are classified based on the sum of the histological characteristics of gonads and behavioral patterns in: continuous, potentially continuous and discontinuous. The present work aims to measure the factors of conditions and development indexes in order to verify variations of the gonades and energetic reserve of the species Pithecopus Nordestinus in the ecological station of Tapacurá, Pernambuco Brazil. In the area of the station, are the forests, slopes and vacant land, in addition to a watershed, represented by the lake formed by the daming of the river Tapacurá. Located in the municipality of São Lourenço da Mata, (formerly Tapera Station), at latitude 8 º 10 ', longitude 35 ° 11 ' and altitude 102 m. For the execution of this work, monthly night expeditions were carried out in the period from February to October of 2018. The following parameters were used to obtain the results: Condition factor (K1), gonadossomatic Index (IGS) and hepatosomatic index (IHS). No significant variations (p. 0.05) were observed between the values of the condition factor (K1), the gonadossomatic Index (IGS) and the Hepatosplenum (IHS), for males p. Nordestinus. Only the females of P. Nordestinus had lower sinister values related to the gonadossomatic index (IGS), (P < 0.05).
