37. The ecology and behavior of thin-spined porcupine (Chaetomys subspinosus, Olfers 1818) in fragments of the Atlantic forest, Ilheus, southern Bahia / Ecologia e comportamento do ouriço-preto (Chaetomys subspinosus, Olfers 1818) em fragmentos de Mata Atlântica do município de Ilhéus, sul da Bahia
The behavioral ecology of thin-spined porcupine (Chaetomys subspinosus, Olfers 1818), threatened rodent endemic from Atlantic forest, was researched in the cacao-growing region of southern Bahia. The knowledge about basic aspects of specie natural history is still incipient. The aim of the present research was to study feeding ecology, behavior temporal orga

38. Text not informed by the author. / Escolha de árvore e sítio de dormir e sua influência na rota diária de um grupo de cebus nigritus, no parque estadual Carlos Botelho, SP
Membros de um grupo social de primatas diurnos reúnem-se ao final do dia num local apropriado para passar a noite. O local de dormida é denominado sítio de dormir e pode consistir em uma ou mais árvores. Hipóteses adaptativas têm sido sugeridas para explicar preferências por árvores e sítios de dormir. O risco de predação tem sido apontado como um

39. Ecology, virulence factors and diversity of Escherichia coli isolated from ballast water, ports areas and bivalves samples in Brazil. / Ecologia, fatores associados à virulência e diversidade de Escherichia coli isolados de amostras de água de lastro, água de regiões portuárias e moluscos bivalves no Brasil.
Escherichia coli was isolated from ballast water, port areas water and bivalves samples. 49.6% (164/331) had multiple antibiotics resistant varied from 2 to 8 antibiotics. From seven virulence associated factors investigated: heat stable toxin (ST), heat labile toxin (LT), aggregative adhesion (EAEC), invasion factor (INV), Shiga-like I toxin (STx-1), Shiga-

40. Analise das estrategias da pesca do camarão de São Francisco, São Sebastião-SP : pela Teoria do Forrageio Otimo / Analysis of the strategies of shrimp fishing in São Francisco, São Sebastião-SP : through the Optimal Foraging Theory
This study uses ecological models derived from the Optimal Foraging Theory (OFT) to understand the decision-making processes among bottom trawling shrimp fishermen at the São Francisco Neighborhood, in the district of São Sebastião, SP, Brazil. Using the theoretical background of Human Behavioral Ecology the aim of this work was to analyze fishermen s str

41. Ecologia reprodutiva e análise de viabilidade de uma população do cágado Hydromedusa maximiliani (Testudines, Chelidae) no Parque Estadual Carlos Botelho / Reproduction ecology and population viability analysis of the neotropical freshwater turtle Hydromedusa maximiliani (Testudines, Chelidae) at the Parque Estadual Carlos Botelho, São Paulo, Brazil
The reproductive strategies of Hydromedusa maximiliani at the Carlos Botelho State Park, SP, was verified by X-ray in females and juveniles between September 2007 and December 2008. Throughout the study two reproductive seasons were detected, both beginning in September. From a total of 33 X-rayed females, only 19 showed eggs, and three of them showed eggs i

42. Ecologia e taxonomia da associaÃÃo de Copepoda Harpacticoida no talude da Bacia de Campos , RJ, Brasil
Taxonomy and ecology of Copepoda Harpacticoida from sediments of Campos Basin Slope are presented here (chapter 1), as well as the description of threee new species of Echinopsyllus (chapter 2) and a discussion concerning new insights for geographic and bathyme tric distribution of Ancorabolidae (chapter 3). A total of 44 stations were sampled along nine tra

43. Determinants of ant communities in Restinga / Determinantes de comunidades de formigas em restinga
O litoral brasileiro apresenta aproximadamente 9.200 quilômetros de extensão, das quais 5.000 km são ocupados por ecossistema de Restinga. Este ecossistema é um conjunto de formações vegetacionais que se desenvolvem em dunas e cordões arenosos do período Quaternário dentro do domínio da Floresta Atlântica. As espécies de plantas que ocorrem em Re

44. Distribuição espacial e temporal, inimigos naturais e tabela de vida ecológica de Diaphorina citri Kuwayama (Hemiptera: Psyllidae) em citros em São Paulo / Spatial and seasonal distribution, natural enemies and ecological life table of Diaphorina citri Kuwayama (Hemiptera: Psyllidae) in citrus groves in São Paulo
O "huanglongbing" (HLB), ou "greening" dos citros, tem sido considerada a pior e mais destrutiva doença que ocorre em cultivares comerciais de citros do mundo. Até hoje, não se conhecem medidas eficientes para o controle da doença. Apesar disso, são recomendadas três medidas que podem reduzir a disseminação da mesma, (1) propagação de material sadi

45. História natural e interação flores-besouros em espécies de Cerrado / Natural history and flower-beetle interactions in Cerrado species
Plant-animal interactions, such as pollination, are a key element in many terrestrial communities. The study of who interacts with whom is an important approach for understanding ecological and evolutionary processes. In some tropical communities, up to one quarter of all plant species may be pollinated by beetles. They are an ancient and much diversified in

46. Levantamento, área de vida, uso e seleção de hábitat de Falconiformes na região central do estado de São Paulo / Survey, home range, habitat use and selection of the Falconiformes in the central region of the state of São Paulo
Raptors, similarly to other animal groups, are not randomly distributed in the different habitats in the terrestrial landscape. Knowing and understanding the factors (and implications) influencing these species to chose a certain habitat are essential in ecological studies. This subject has become even more important not only because of the lack of informati

47. ETOGRAMA BÁSICO, ECOLOGIA TERMAL E DIMORFISMO SEXUAL DE Tropidurus itambere RODRIGUES, 1987 (SQUAMATA: TROPIDURIDAE) EM UMA ÁREA DE CAMPO RUPESTRE NO SUDESTE DO BRASIL / ETOGRAMA BÁSICO, ECOLOGIA TERMAL E DIMORFISMO SEXUAL DE Tropidurus itambere RODRIGUES, 1987 (SQUAMATA: TROPIDURIDAE) EM UMA ÁREA DE CAMPO RUPESTRE NO SUDESTE DO BRASIL
The aim of this study was to elaborate a basic ethogram for adult individuals of Tropidurus itambere, through observations accomplished in field and outdoor and indoor enclosures and to study the thermal ecology and the sexual dimorphism of the lizards, on December 2006 and between February and November 2007. The observations of the behaviors were accomplish

48. Trophic niche of Tropidurus hispidus (Sauria: Tropiduridae) in restinga environment / Nicho trofico de Tropidurus hispidus (Sauria: Tropiduridae) em ambiente de restinga
The diet is one of the main atributes of the ecological niche of animal species. Generally, the individuals of a population are considered ecologically equivalent in ecological studies that focus on resource use. Nevertheless, this approach has been inadequate to correctly describe resource use by various species, as demonstrated by empirical data. Intrapopu
