13. Influência da composição de substrato do recife na atividade e distribuição de peixes zoobentívoros no arquipélago de Fernando de Noronha, Pernambuco / The influence of substratum composition on the activity and distribution of benthic carnivorous reef fishes of the Fernando de Noronha Archipelago
Reefs provide shelter and food for several fish species and, thus, there may be a correlation between the abundance and behaviour of fishes and the reef bottom composition-Physical factors, such as water movement and depth, may also have a profound impact in species distribuiton and activity on reefs. Here, the possible relationship between the distribution

14. Estratégias de forrageamento e evitação de predadores em Charadriidae e Scolopacidae na Baía de Todos os Santos, Bahia, Brasil
Shorebirds (Charadriidae and Scolopacidae) are a notable component of coastal ecosystems, especially of bays and estuaries. The great majority of these species is migratory, conducting long trips between Arctic and Sub-arctic breeding grounds and temperate and tropical wintering grounds. My general objective of this thesis was to analyze the foraging and pre

15. 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

16. Mamíferos de médio e grande porte em uma área alterada no cerrado : estrutura da comunidade, sobreposição de nicho e densidade
Medium and large sized mammals in a disturbed area in the Cerrado: community structure, niche overlap and density. Medium and large sized mammals are affected by fragmentation and habitat changes, and in Cerrado this group corresponds to species preferentially nocturnal, generalist in habitat use and with scarce information about density in modified environm

17. Morphological and glandular changes associated th the age polyethism of Polybia paulista (Hymenoptera: Vespidae) / Mudanças morfológicas e glandulares associadas ao polietismo etário em Polybia paulista (Hymenoptera: Vespidae)
The division of labor is a central theme in the study of social insects. In bees and wasps this ability is regulated for age castes of the workers. In Apis mellifera, several authors have shown selective activation of the glands for job in colony, and reduced body weight for foraging. In social wasps age polyethism among workers is a relatively unexplored su

18. DESENVOLVIMENTO PÓS-EMBRIONÁRIO, OOFAGIA E RELAÇÃO ENTRE AS INTERAÇÕES DE DOMINÂNCIA E A ATIVIDADE FORRAGEADORA NA VESPA SOCIAL Mischocyttarus cassununga (VON IHERING, 1903) (HYMENOPTERA, VESPIDAE)
A vespa social Mischocyttarus cassununga ocorre no sudeste do Brasil, Bahia e Santa Catarina e apresenta fundação do tipo independente por meio de uma fêmea inseminada ou por uma associação destas fêmeas, sendo o papel social dos indivíduos determinado por meio de interações de dominância. O objetivo deste trabalho foi caracterizar o desenvolviment

19. Atividade de meliponíneos (Hymenoptera: Apidae) em ambiente protegido / Meliponin activity (Hymenoptera: Apidae) into protected environment
In order to use tribe Meliponin bees into protected environment pollination programs, this work has aimed to evaluate different Meliponin species into greenhouse. The study was made at UFV, using a greenhouse, with an area of 115,2 m, 3,5 m height in the sides and 5,2 m in the upper part. Initially six Meliponin species were studied (Melipona quadrifasciata,

20. Influência das precipitações pluviométricas e da atividade forrageira das abelhas africanizadas (Apis mellifera L.) no comportamento higiênico / Influence of rainfall and foraging activity on hygienic behavior of Africanized honey bees (Apis mellifera L.)
Hygienic behavior (HB) of honey bees (Apis mellifera ) is a useful and selectable characteristic for resistance to diseases. However, in order to efficiently evaluate and select for this behavior we need to understand the mechanisms involved and how environmental factors influence HB. We examined how time of the day, bee age and behavioral ontogeny, and clim

21. O papel das rotas e da obtenção de informações sobre a eficiência no forrageio de dinoponera quadriceps em ambiente natural
In this study, we investigated the role of routes and information attainment for the queenless ant species Dinoponera quadriceps foraging efficiency. Two queenless ant colonies were observed in an area of Atlantic secondary Forest at the FLONA-ICMBio of Nisia Floresta, in the state of Rio Grande do Norte, northeastern Brazil, at least once a week. In the fir

22. 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

23. 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

24. Variação Temporal da Atividade de Forrageio de Cupins (Insecta, Isoptera) sobre Iscas de Papel Higiênico em Hidrolândia, Goiás / Temporal variation of termite (insecta, isoptera) foraging activity on toilet paper bait in Hidrolândia, Goiás
Cupins são insetos sociais com de 2800 espécies descritas, que se alimentam de celulose em vários estágios de decomposição. Baseando-se na proporção de matéria orgânica encontrada no trato digestório estes são classificados em grupos alimentares: grupo I (não Termitidae), comedores de serapilheira, granívoros e xilófagos; grupo II (Termitidae)
