Gauromydas Wilcox, Papavero & Pimentel, 1989 are giant flies, and include the largest fly known, G. heros (Perty, 1833). This genus was originally erected to group four Neotropical species, namely G. apicalis (Wiedemann, 1830), G. autuorii (d'Andretta, 1951), G. heros, and G. mystaceus (Wiedemann, 1830). As with most of the remaining Mydidae, adults of Gauromydas are very rarely collected. We h...

Spatial distribution and spatial relationships in capture rates of understorey insectivorous birds and density of arthropods were investigated in a patch of upper montane rain forest in Minas Gerais state, southeastern Brazil, from January to December 2004. The composition of the arthropod fauna collected was similar to that reported for other tropical forests, with predominance of Araneae, Col...

A total of 107 leptodactylid frogs representing 6 species, Leptodactylus fuscus (n 5 15), Leptodactylus leptodactyloides (n 5 9), Leptodactylus mystaceus (n 5 2), Leptodactylus ocellatus (n 5 31), Leptodactylus petersii (n 5 31), and Leptodactylus pustulatus (n 5 19), collected in the Brazilian state of Tocantins, were examined for helminths. One species of Digenea (Catadiscus marinholutzi), 6 ...

Body size is directly linked to key life history traits such as growth, fecundity, and survivorship. Identifying the causes of body size variation is a critical task in ecological and evolutionary research. Body size variation along altitudinal gradients has received considerable attention; however, the underlying mechanisms are poorly understood. Here, we compared the growth rate and age struc...
