1. Responses of water mite assemblages (Acari) to environmental parameters at irrigated rice cultivation fields and native lakes
ABSTRACT Many studies have revealed that water mite communities can be affected by the physical and chemical parameters of the water. The similarity between the water ‘mite assemblages in local water bodies and in irrigated rice areas can be a way to measure the water conditions, enabling an assessment of the anthropic impact in the environment. The aim of

2. Estimating the relative abundance of small mammals when there is no record of catching effort
ABSTRACT Estimates of local population abundances, which require carefully designed sampling procedures, can provide valuable information on population size and density. Even though small mammals are one of the most widely studied vertebrate groups, many surveys have not recorded basic information to estimate local abundances, for instance catching effort. H

3. Modelos teóricos de distribuição de abundância das espécies para caracterização da diversidade biológica e a utilização de diferentes medidas de abundância / Theoretical models of species abundance distribution to characterize the biological diversity and the use of different measures of abundance
The species abundance distributions (SADs) are considered an informative way to describe the biological diversity revealling one of the most wellestablished patterns in ecology: the predominance of rare species in biological communities. The generality of such pattern made it relevant to the analysis of other biodiversity parameters an to induce the developm

4. Soil macrofauna under integrated crop-livestock systems in a Brazilian Cerrado Ferralsol.
Abstract ? The objective of this work was to assess the effects of integrated crop-livestock systems, associated with two tillage and two fertilization regimes, on the abundance and diversity of the soil macrofauna. Four different management systems were studied: continuous pasture (mixed grass); continuous crop; two crop-livestock rotations (crop/pasture an

5. Diversity and abundance of orchid bees (Hymenoptera: Apidae, Euglossini) in a tropical rainforest succession
Euglossine bee males are easily lured to chemical baits imitating natural fragrances gathered by bees, providing a widely applied measure for estimating the diversity and abundance of euglossines. In here, I report the composition of euglossine bees in three lowland rainforest habitats of Peru, a primary old forest, a reforested and managed forest, and a ver

6. Ictioplâncton na Unidade de Conservação Reserva Biológica Marinha do Arvoredo e Áreas Costeiras Adjacentes, Santa Catarina, Brasil
Arvoredo Island (Santa Catarina, Brazil) and its surrounding area were defined as Conservation Unit (CU) in the category of Biological Reserve in 1990. Biological Reserves are protected areas that have complete and permanent preservation of local flora and fauna, thus contributing to the increase of abundance and diversity of species. This research aimed at

7. Experiment and Erlebnis : the dimension of life as pathos / Experimento e vivencia : a dimensão da vida como pathos
The objective of this research is to analyze Nietzsche s formula become who you are . It is an alteration of Pindaro s expression made by Nietzsche, which has worried him since he was a student until being published with the subtitle of Ecce homo. Our hypothesis is that become who you are formula can be understood through the concept of experience (Erlebnis)

8. Study of the community of bats of a cárstic area of Alto Ribeira -SP. A comparison with 1980 / Estudo da comunidade de morcegos na área cárstica do Alto Ribeira-São Paulo. Uma comparação com 1980
The survey on Brazilian cave bats was initiated by TRAJANO (1981) that between 1978 and 1980, studied the community that uses caves in a carstic area of Alto Ribeira, south of the State of São Paulo. Another studies had been followed in the north of São Paulo, Distrito Federal and Bahia, and recent works are being carried through in new areas, filling an i

9. Biologia da polinização e reprodução de especies de Melastomataceae do Parque Nacional da Serra da Canastra (MG) / Pollination and reproductive biology of Melastomataceae from Serra da Canastra National Park (MG, Brazil)
This study examines the reproductive phenology, pollination ecology, and mating systems of 10 species of Melastomataceae that occur in the Serra da Canastra National Park, Minas Gerais. Seasonality exposes plants to periodic changes in quality and abundance of resources. Flowers of many species can be found throughout the year, but there are well-defined pea

10. BIODIVERSITY OF LEAF-LITTER ANTS IN THE BODOQUENA MOUNTAIN RANGE NATIONAL PARK MATO GROSSO DO SUL BRAZIL / BIODIVERSIDADE DE FORMIGAS DE SERAPILHEIRA DO PARQUE NACIONAL DA SERRA DA BODOQUENA MS
This study represents the first systematic Formicidae survey in the Bodoquena Mountain Range National Park state of Mato Grosso do Sul - Brazil. We have compared two distinct areas in domain of Deciduals Forests along the Bodoquena mountain range with 10 sites: 5 in the north portion and 5 in the south portion. Our first goal was to describe the leaf-litter

11. Ecology of phytoplankton community in two branches of Billings Reservoir (São Paulo, SP) with different trophic states / Ecologia da comunidade fitoplactônica em dois braços da Represa Billings (São Paulo, SP) com diferentes graus de trofia
The aim of this work was to compare the phytoplankton community composition and diversity in Rio Grande and Taquacetuba branches (Billings Reservoir) and to determinate its controlling factors. Water samples were collected in six depths on February, May, August and November 2005. Physical and chemical variables and the phytoplankton community were analyzed.
