1. Population Fluctuation of Termitofauna (Blattodea: Isoptera) in Six Forest Fragments of the Mata Atlântica
ABSTRACT The objective of this work was to evaluate the forest restoration of the basin of Guapiaçu river in Cachoeiras de Macacu, Rio de Janeiro state, using the families of Termites as tools for environmental assessment. We analyzed the population fluctuation and feeding guilds of the families of Termites: Kalotermitidae, Rhinotermitidae and Termitidae. S

2. The phyllostomid bat (Mammalia, Chiroptera) assemblage in a fragmented landscape in Midwestern Brazil
RESUMO Os morcegos são a segunda maior ordem de mamíferos, com diversos hábitos alimentares e grande importância ecológica. A antropização possui diversos efeitos nas comunidades animais e o Cerrado Brasileiro, uma savana neotropical, tem sido severamente afetada pela atividade humana. O objetivo deste estudo foi avaliar a distribuição da assembleia

3. Dinâmica da partilha dos recursos alimentares entre peixes piscívoros numa lagoa do semiárido brasileiro.
A dinâmica da partilha de recursos, entre espécies de uma mesma guilda trófica, reduz a competição e possibilita a coexistência entre elas. Essa partilha pode decorrer do desempenho ecológico diferenciado resultante de variações morfológicas e da utilização diferenciada dos recursos alimentares. Neste estudo, avaliou-se a dinâmica da partilha de

4. Composição e sazonalidade de borboletas frugívoras no cerrado, com ênfase na relação fenológica entre Eunica bechina (Nymphalidae: Biblidinae) e sua planta hospedeira Caryocar brasiliense (Caryocaraceae) / Composition and seasonality of fruit-feeding butterflies in the cerrado savanna, with emphasis on the phenological relationship between Eunica bechina (Nymphalidae: Biblidinae) and its host plant Caryocar brasiliense (Caryocaraceae)
In many tropical environments, rainy and dry seasons alternate. The dryer season has decreased leaf availability and the nutritional quality of leaves is also low - thus it is an unfavorable period for herbivorous insects and generates seasonal oscillations in their populations. The cerrado is a neotropical seasonal biome characterized by a hot/rainy and a c

5. Spider diversity in a rice agroecosystem and adjacent areas in southern Brazil / Diversidad de arañas en un agroecosistema de arroz y áreas adyacentes en Brasil meridional
Las arañas son uno de los grupos de depredadores terrestres más numerosos que se encuentran en diversos ambientes tales como agroecosistemas y áreas circundantes. Es importante investigar los cambios en diversidad de arañas en agroecosistemas debidos al manejo agrícola. Este trabajo evaluó riqueza, abundancia, y similitud de arañas en diferentes etapa

6. Meso and microhabitat analysis and feeding habits of small nektonic characins (Teleostei: Characiformes) in Neotropical streams
The habitat use and feeding habits of a set of nektonic fish species often found in small low-gradient streams in Brazil were investigated. The core species in the present study was Knodus moenkhausii (Eigenmann & Kennedy, 1903), the most abundant of five species in the nektonic guild. Records of the species in 22 streams indicate that K. moenkhausii is asso

7. Oferta de frutos e frugivoria por aves, em espécies do gênero Miconia Ruiz &Pav. (Melastomataceae) em duas áreas do Cerrado / Fruit supply and bird frugivory in species of Miconia Ruiz &Pav. (Melastomataceae) in areas of Cerrado, Brazil
The goals of this study were: to determine the seasonality, duration and fruit supply peaks of Miconia albicans, M. ibaguensis, M. affinis, M. theaezans and M. chamissois; to verify the nutritional quality of these fruits (Chapter I); to evaluate which birds feed on these fruits, and to verify which birds are the main dispersers of each Miconia species (Chap

8. Composition and trophic structure of fish communities in the Ribeirão Bananal sub-basin, Parque Nacional de Brasília, biome Cerrado, DF / Composição e estrutura trófica da comunidade de peixes de riachos da sub-bacia do Ribeirão Bananal, Parque Nacional de Brasília, bioma Cerrado, DF
The purpose of this study was determined the composition and the trophic structure of fish communities in the Ribeirão Bananal sub-basin, which belongs to a well preserved Cerrado area in the National Park of Brasília, Brazil. Furthermore, due to a marked sazonality in this biome, it was examined the influence of environmental variations on the fish specie

9. Ecologia trófica da comunidade de peixes do reservatório do Lobo (Broa), Brotas-Itirapina/SP, com ênfase à introdução recente da espécie alóctone Cichla kelberi (Perciformes, Cichlidae).
The introduction of predatory species has carrying deep modifications on the original fish wildlife structure at aquatic environments. The feeding spectrum characterization of fish community from Lobo Reservoir (Broa), beside providing information about the species biology and establishing trophic guilds, made possible the follow-up of trophic alterations du

10. Species assembly rules and the biodiversity-ecosystem functioning relationship / Regras entre assemblÃias de espÃcies: relaÃÃo entre biodiversidade e funcionamento do ecossistema
The biological diversity of ecosystems has important implications for their functioning. However, in order for reliable predictions to be made on the effects of species extinctions and/or additions on particular ecosystem functions, accurate knowledge is required on the ways in which species interact. These interactions in turn are important drivers of commu

11. Variación en la composición de comunidades de aves en la Reserva de la Biosfera Montes Azules y áreas adyacentes, Chiapas, México
In order to compare the bird communities' composition and their possible relationships, I sampled monthly from January to December 2002 in the Biosphere Reserve Montes Azules (REBIMA) and adjacent areas, Chiapas, Mexico. Data were obtained during 48 days of fieldwork in an area of 60 ha by site. I recorded 133 species, which represent 36% of the total number

12. The guild of fruit-feeding butterflies in a fragmented landscape in the upper Paraiba River basin, São Paulo, Brazil / A guilda de borboletas frugivoras em uma paisagem fragmentada no Alto Paraiba-SP
Most of the Atlantic Forest in the State of São Paulo occurs in fragments of various sizes. Previous studies indicate that forest fragmentation affects the butterfly community, changing its composition and diversity. In view of the importance of knowing the fauna of these forest remainders, the present work had the objective to characterize the assemblage o
