1. Activity budget and social behavior of urban capuchin monkeys, Sapajus sp. (Primates: Cebidae)
ABSTRACT Constant changes in natural environments impose challenges to wild animal populations, especially those that depend on social life. We gathered data on the activity budget and social interactions of a capuchin monkey (Sapajus sp.) group of 17 individuals confined to an urban green area receiving human food supplementation. We observed the capuchins

2. Predatory behavior of three centipede species of the order Scolopendromorpha (Arthropoda: Myriapoda: Chilopoda)
ABSTRACT Studies related to centipede feeding and predatory behavior are rare in the literature, and are limited to observations made during fieldwork. Furthermore, they lack descriptions of prey capture. We conducted a laboratory experiment using South American specimens of Scolopendra viridicornis Newport, 1844 (n = 5), Otostigmus tibialis Brölemann, 1902

3. Some aspects of chicken behavior and welfare
Brazil is the world leader in broiler production and export. It achieved this position mainly to its excellent supply chain structure and climate, which favor poultry and grain production throughout its territory. Although Brazilian egg production is not as important as broiler production, this segment presents great potential of increasing its share in the

4. Presentes nupciais em Paratrechalea ornata Carico, 2005 (Araneae; Trechaleidae) : quais os canais de sinalização reconhecidos pelas fêmeas no contexto pré-copulatório?
The Order Araneae is widely known for having a great variety both in terms of morphology and behavior, from which I highlight the genus Paratrechalea Carico, 2005, whose males construct a nuptial gift from a prey wrapped in silk that is offered to the female during courtship. Recent studies indicate that this gift-giving behavior in spiders represents a male

5. 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

6. Diferenças sexo/etárias no Forrageamento de Cebus nigritus em área de Mata Atlântica / Age/sex differences in foraging behavior of Cebus nigritus in Atlantic Forest
Após anos do estudo moderno da ecologia e comportamento dos primatas, a juventude, definida como o período entre o desmame e a maturidade sexual, permanece sendo uma das fases menos compreendidas do ciclo de vida destes animais. Existem quatro teorias gerais para explicar os padrões de forrageamento e escolha da dieta de primatas juvenis. A primeira afirm

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. Reproductive strategies and feeding ecology of the aquatic snakes of the tribe Hydropsini (Dipsadidae, Xenodontinae). / Estratégias reprodutivas e ecologia alimentar de serpentes aquáticas da tribo Hydropsini (Dipsadidae, Xenodontinae).
The tribe Hydropsini comprises three genera of snakes. Information on food habits is scarce. However previous data indicate that species feed mainly upon fishes but also eat anurans. The Hydropsini are oviparous or viviparous and the polymorphism is suggested for some species. Other reproductive traits are unknown for most species. On the other hand, the phy

9. Abelhas eussociais (Hymenoptera, Apidae) que ocorrem em jardins urbanos em Juiz de Fora, MG: recursos florais e atividade de voo
O processo de urbanização modifica o ambiente, alterando os locais de nidificação e diminuindo as fontes de recursos tróficos de muitas espécies de abelhas. Este estudo teve como objetivo estimar a riqueza de abelhas eussociais, assim como as plantas visitadas por essas abelhas em um ambiente antrópico. Além disso, verificou-se a influência da tempe

10. Food web dynamics under indirect effects mediated by trait and density / Dinâmica de redes tróficas sob efeitos indiretos mediados por traço e densidade
Predation, classically described as the negative effect of the predator on the density of their prey, will be examined for their effects on the behavior of prey,in the form of antipredator responses. Antipredator responses may arise on the morphology, physiology and/or the behavior of prey, by predation or by the mere presence of the predator, in

11. 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

12. 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
