AbstractThe Peregrine Falco peregrinus, is an Nearctic migrant to Brazil where its status in central Brazil is still poorly known. Herein we present a compilation of records of the species from the state of Tocantins and comment on its use of a wintering site in the state of Goiás. These records show that the Tocantins-Araguaia River Basin is a migration route for the species, and therefore a mid-continental migration route through the interior of South America.

This study aims to determine which of twelve environmental parameters (five physicochemical and seven hydromorphological) influence on the fish assemblage structure of the lower Mortes River basin located in the Bananal floodplain of the Araguaia River basin, Central Brazil. Sampling was conducted in six stretches of 1000 m each during the high and low waters. Fish were captured using gill nets and environmental parameters were measured by portable equipment or determined visually. The co-inertia analysis indicated that two physicochemical (dissolved oxygen and water transparency), and four hydromorphological (channel width and depth, riparian vegetation cover and type of the riverside substrate) parameters structure the fish assemblages, both driven by the regional hydrological patterns (flood pulse). These results are explained by fish-environmental parameters relationship characteristic of the aquatic Neotropical systems.

Este estudo objetiva avaliar o fator de condição (K) de cinco espécies de peixes (Serrasalmus rhombeus, Psectrogaster amazonica, Loricaria cataphracta, Panaque nigrolineatus e Squaliforma emarginata). As coletas foram realizadas utilizando-se quatro jogos de redes de malhar e cinco armadilhas, os quais foram colocados ao longo de um trecho de 1000 m das 17:00 às 7:00. Os peixes coletados foram identificados taxonomicamente, pesados (g) e medidos (comprimento standard; mm). A condição física dos peixes foi calculada pelo fator de condição (K=W/L³) e comparada por grupo de cursos de água utilizando um teste de Kruskal-Wallis. Das cinco espécies consideradas S. emarginata e P. amazonica mostraram diferenças na condição física por grupo de cursos de água. Os maiores valores de K de ambas as espécies correspondem aos espécimes localizados em cursos de água de cabeceira, enquanto que baixos valores são encontrados em peixes dos cursos de água na planície.

A New Species

We describe a new species of Ololygon from the Cerrado biome, Central Brazil. The new species is assigned to the Ololygon catharinae species group based in morphological attributes. Ololygon goya sp. nov. in known only from type locality—Sítio d’Abadia municipality, State of Goiás—and associated with riparian environments connected to seasonal dry forest on the banks of the Corrente river, a tributary of the Paranã river basin. The new species is characterized by the combination of the following characters: medium size (24.4–38.8 mm SVL); snout subovoid in dorsal view; canthus rostralis well defined; males with hypertrophied forearms and nuptial pads; inguinal region and hidden surfaces of thigh with irregular dark brown spots on pale yellowish background. We also describe the external morphology and oral morphology of tadpoles, and the advertisement calls of the new species.
