This note reports data on occurrence of the echimyid Kannabateomys amblyonyx in Minas Gerais State, southeastern Brazil. Data were obtained from consult to 26 museums, bibliography search and field sampling. We found nine municipalities with species records, eight within the Atlantic Forest biome and one in the transitional area between the Atlantic Forest and Cerrado. Habitats occupied comprised bamboo groves in Montane Stational Semidecidual Forest, Submontane Stational Semidecidual Forest and bamboo patches located in middle of open area, originally covered by Submontane Stational Semidecidual Forest. Potential impacts detected were deforestation, fires, hunting and the presence of livestock and domestic dogs. © 2012 by Unisinos. Source

Antlions (Neuroptera: Myrmeleontidae) are predators commonly found in the tropical regions. There are few studies on their biology and natural enemies in the Neotropics. The aim of this study was to sample larvae of Myrmeleon brasiliensis (Navás 1914) in natural environments in order to identify their parasitoids and estimate levels of parasitism. Larvae of M. brasiliensis, from first to third instars, were collected in a natural forest in Aquidauana, Mato Grosso do Sul state, Brazil from Feb 2001 to Jan 2002. In total, 161 larvae of M. brasiliensis were collected and reared in the laboratory. They were fed daily with leaf-cutting antworkers and third instar larvae of fruit flies. Two parasitoid species emerged from larvae of M. brasiliensis: Hockeria eriensis (Wallace 1942) (Hymenoptera: Chalcididae) and Paravilla sp. near stheno (Wiedemann 1828) (Diptera: Bombyliidae, Anthracina). This is the first record of M. brasiliensis's parasitoids in Brazil. All juveniles of the antlion were killed by the parasitoids after pupation, and only an adult of both parasitoid species have emerged per pupa of M. brasiliensis. Source

Cajuzinho-do-cerrado (Anacardium humile A. STHIL.) has a wide distribution in areas of the Midwest Brazilian Cerrado, it’s fleshy fruits are widely used by regional populations in an extractive way. Despite the promising agro-economic potential, few studies have been developed to domestication of the species. The study aimed to evaluate twenty different matrices of cajuzinhodo- cerrado, checking how the weight and the storage of cashew nuts are related with the emergence percentage and biometric variables of seedling newly formed. Fifty fruits were collected from twenty different matrices of Anacardium humile inside the Emas National Park, Mineiros, GO. All fruits collected showed matured, developed and yellow pedicels. Seven matrices had an excess number of fruits, so it was harvested 50 other cashew nuts, which were stored in cold and dry chamber for a period of six months. The seedlings emergence rates were satisfactory in both, total experiment and for progeny. Reproduction of Anacardium humile through cashew nuts proved to be promising. Weight of cashew nuts did not affect emergence rates or seedlings biometrics. The storage of nuts for six months for planting in autumn was inefficient. © 2014, Universidade Federal de Santa Maria.

The present study aimed to investigate the feeding habits of Lontra longicaudis in a pool system within the Private Reserve of Natural Patrimony (RPPN) Usina Maurício, located in Paraíba do Sul river basin, Atlantic Forest of southeastern Minas Gerais State. The diet composition was determined based on the identification of items present in 212 scats sampled between July 2008 and October 2009 in a 4.1 km stretch of the pool system. The found items and its respective percentages of occurrence were: mollusks (0.5%), insects (16.5%), spiders (1.4%), crustaceans (3.3%), fish (96.7%), amphibians (0.9%), snakes (3.8%), birds (2.8%), mammals (8.5%) and fruits (0.5%). Among fish, the identified families and respective percentages of occurrence were: Loricariidae (65.4%), Pimelodidae (42.9%) Cichlidae (22%), Characidae (7.3%), Erythrinidae (3.9%), Synbranchidae (2.4%), Anostomidae (2%). Therefore fish make up the most consumed item in the study area, with the predominance of benthic siluriformes (families Loricariidae and Pimelodidae). Source

We present here a new record for Amphisbaena michelli for the western of Pará State, northern Brazil. The specimen was found in the municipality of Belterra, on the right bank of the Tapajós River, and represents an expansion ca. 350 km west of the previously known geographic distribution of the species. © 2014 Check List and Authors.
