1. Ecologia trófica e ecomorfologia da ictiofauna de igarapés maranhenses
The trophic ecology is one of the most important aspects to understand the role of a species in the community and in the ecosystem functioning. Studies regarding the feeding of fishes coupled to the ecomorphology of a species become important tools in understanding their ecological role and position in the environment. The present study aimed to analyze the

2. Milk composition of franciscana dolphin (Pontoporia blainvillei) from Rio Grande do Sul, southern Brazil
Milk is the only external energy source for mammals in their early stages of life. Its composition varies during lactation in baleen whales and pinnipeds, while only descriptive studies are available for odontocetes. The aim of this work was to identify the components of the milk of franciscana, Pontoporia blainvillei, from southern Brazil. Samples were manu

3. Heterogeneidade do habitat, riqueza e estrutura da assembléia de besouros rola-bostas (Scarabaeidae: Scarabaeinae) em áreas de cerrado na Chapada dos Parecis, MT
Ecological theory of habitat heterogeneity and limited niche-similarity assumes that more heterogeneous environments provide a greater amount and diversity of resources than simple environments, resulting in a greater diversity of species. This study aimed to evaluate the effect of the habitat heterogeneity on the richness of dung beetles and to examine the

4. DISTRIBUIÇÃO E ESTIMATIVAS POPULACIONAIS DO BOTO Inia geoffrensis (DE BLAINVILLE, 1817) (INIIDAE) NO MÉDIO RIO ARAGUAIA (BRASIL CENTRAL)
This is the first study about the abundance and density of the boto Inia geoffrensis using Distance sampling in the Araguaia River (Central Brazil). The study was carried out along a 530 km section of the Middle Araguaia River. The surveys were conducted in May and September 2009 (during falling and dry water seasons), where strip and line transects were emp

5. Development of a Multimetric Index of Ecological Integrity for streams in the urban area of Campo Grande (Mato Grosso do Sul), based on benthic macroinvertebrates / Desenvolvimento de um Índice Multimétrico de Integridade Ecológica para córregos na área urbana de Campo Grande (Mato Grosso do Sul), baseado em macroinvertebrados bentônicos
Water pollution is a growing problem, especially in the water courses that flow through urban centres, receiving residential, commercial and even industrial effluents. The small amount of control that exists is often done by means of physical, chemical and bacteriological analyses. The lack of a biological alternative may be due to the paucity of research in

6. Conservação de aves de sub-bosque em paisagens fragmentadas: Importância da cobertura e da configuração do hábitat / Influence of habitat amount, fragment size and connectivity in Atlantic Forest bird species conservation
Landscape aspects such as habitat amount, fragment size and connectivity, have been suggested as key features for maintaining species in altered landscapes, and thus are essential to be modeled and comprehended for management and conservation purposes. To test their effects on understory Atlantic forest bird species, we built models with variables representi

7. Estudo do efeito da fragmentação do habitat sobre padrões de biodiversidade
Despite the complexity of factors that influence the growth and dispersion of individuals in species, some general patterns are observed in the study of ecosystems. One of these patterns is the relationship between the number of species and the size of the area occupied by these species (species-area relationship). This relationship is one of the oldest rule

8. MESOFAUNA EDÁFICA E A TAXA DE DECOMPOSIÇÃO DA RESTEVA DE TRÊS SUCESSÕES DE CULTURA EM SISTEMA PLANTIO DIRETO
The mesofauna soil is composed primarily of Mite and Collembola (75 to 97% of total arthropod fauna of the soil) is one of the few groups of human beings who show enormous diversity of forms, habitat and behavior, being found in almost all places accessible to wildlife because they live in regions epi, hemispheric and euedáficas. The components of mesofauna

9. Characterization of benthic macrofauna in estuaries of the rivers package and Pirangi - Cearà - Brazil / CaracterizaÃÃo da macrofauna bentÃnica dos estuÃrios dos rios Pacoti e Pirangi - Cearà - Brasil
The distribution of organisms regarding their habitat plays an important role in ecological studies. The nature of this distribution provides an initial view on the types of ecological processes regulating the assemblages and the populations. The present study aims to characterize and to compare the benthic macroinfauna community structure, correlating it wi

11. Habitat preference of freshwater snails in relation to environmental factors and the presence of the competitor snail Melanoides tuberculatus (Müller, 1774)
Our objective is to evaluate the habitat preference of freshwater snails in relation to environmental factors and the presence of the competitor snail Melanoides tuberculatus. In the first phase, snails was collected at 12 sites. This sampling sites presented a degree of organic input. In the second phase 33 sampling sites were chosen, covering a variety of

12. Inbreeding and building up small populations of stingless bees (Hymenoptera, Apidae)
A study of the viability of small populations of Hymenoptera is a matter of importance to gain a better zoological, ethological, genetical and ecological knowledge of these insects, and for conservation purposes, mainly because of the consequences to the survival of colonies of many species of bees, wasps, and ants. Based on the Whiting (1943) principle, Ker
