2024
Overview
Espécimes (50) de Leptophis nigromarginatus do Norte do Brasil, Peru, Equador e Colômbia foram examinados quanto à composição do conteúdo estomacal. A maioria das presas eram pererecas, especialmente as da família Hylidae (96%). A maioria dos anuros identificados pertence ao grupo de espécies Scinax ruber (14%) e Scinax sp. (8%). Ambos os sexos predaram itens de pequeno porte (1,8-4,4% do comprimento focinho-cloaca da serpente), mas as fêmeas capturam presas maiores que os machos. Leptophis nigromarginatus parece manipular as presas capturadas antes da ingestão, uma vez que a maioria das presas (68%) foi engolida pela cabeça. Há uma correlação positiva entre o comprimento do focinho-cloaca da fêmea e o tamanho da presa e entre o comprimento da cabeça e o tamanho da presa.
