1. Ecology, behavior and natural history of the harvester ant Pogonomyrmex naegelii (Formicidae, Myrmicinae) in cerrado vegetation: activity schedule, diet, home range, nest structure and demography / Ecologia, comportamento e história natural da formiga ceifeira Pogonomyrmex naegelii (Formicidae, Myrmicinae) em cerrado : ritmo biológico, dieta, área de vida, estrutura e demografia dos ninhos
Pogonomyrmex naegelii belongs to the group known as harvester ants, which collects and stores seeds in underground chambers for later consumption. These ants can be found in both warm temperate and tropical regions around the world, especially in areas of semiarid to arid vegetation, although they may also be found in moist habitats. The following study prov

2. Aspectos da história de vida de Guadua tagoara (Nees) Kunth (Poaceae:Bambuseae) na Serra dos Órgãos, RJ
Guadua tagoara (Nees) Kunth is a large sized bamboo native of the Brazilian Atlantic Rain Forest, with a semi-scandent habitat, pachymorphic rhizome and thorns for fixation on trees. Nowadays this bamboo is considered an invasive species in secondary forests, where its populations are supposedly in expansion. The general objective of this study, developed in

3. Interações entre plantas e beija-flores numa comunidade de Floresta Atlantica Montana em Itatiaia, Rio de Janeiro
Studies of plant-pollinator interactions in vegetation communities can contribute to an understanding of evolutionary and ecological questions. This study sought to relate floristic composition, floral features, resource availability and hummingbird visitation in an ornithophilous assemblage in southeastern Brazil. During two years, data on life form, habita

4. Hippocampal EEG and Unit Activity Responses to Modulation of Serotonergic Median Raphe Neurons in the Freely Behaving Rat
Hippocampal EEG, GABAergic interneurons, and principal cells were recorded simultaneously as rats foraged within one of three environments both before and after modulation of serotonergic inputs to the hippocampus. Median raphe microinjections of the 5-HT1a receptor agonist 8-OH-DPAT were made to produce inhibition of serotonergic neurons in this region. Suc
