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. The effect of increased light intensity on the aggressive behavior of the Nile tilapia, Oreochromis niloticus (Teleostei: Cichlidae)
Animals show behavioral and physiological changes that emerge in response to environmental perturbations (i.e., emergency life-history stages). In this study, we investigate the effects of light intensity on aggressive encounters and social stability in groups of adult male Nile tilapia, Oreochromis niloticus (Linnaeus, 1758). The study compared the behavior

3. Como os machos de Diastatops obscura (odonata: libellulidae) decidem o vencedor de uma disputa territorial? / HOW THE MALES OF Diastatops obscure (Odonata: Libellulidae) DECIDE THE WINNER OF A TERRITORIAL DISPUTE?
Apesar das brigas entre os machos serem frequentes e de existirem modelos teÃricos que postulam possÃveis regras usadas para decisÃo do vencedor, pouco suporte empÃrico direcionado ao entendimento das brigas tem sido encontrado. Provavelmente esse fato ocorre devido à dificuldade em identificar quais caracterÃsticas determinam a capacidade de luta (RHP

5. Comportamento social de cabras em lactação após reagrupamento =Social behaviour in lactating dairy goats after regrouping / Social behaviour in lactating dairy goats after regrouping
Background: Like other farm animals, domestic goats may react adversely to unfamiliar individuals, and aggression can be minimized by avoiding the introduction of new individuals into established groups. In modern dairy herds, regrouping according to age, nutrient requirements, lactation period and milk yield level is a common management practice to enhance

6. Seasonal variation in the behavior of captive alpine musk deer, Moschus sifanicus, in Xinglongshan Musk Deer Farm, of China
Musk deer farming has the potential to be an effective conservation tool for the protection of musk deer as well as the production of valuable musk. To be successful, this requires a thorough understanding of the behavior of captive musk deer in order to improve their reproductive success and management. Between August 2005 to January 2006, the behavior samp

7. OrganizaÃÃo social de elasmobrÃnquios na Reserva BiolÃgica do Atol das Rocas, Brasil
Many animals tend to form social groups, segregating individuals from different classes, such as males and females, adults and subadults, and even large and small specimens of the same species. In order to better understand the behavior of elasmobranches in an insular environment, the social organization of the nurse shark, Ginglymostoma cirratum, (Bonnaterr

8. Interaction of the nuclear receptors with its ligands: Structural studies of the thyroid hormone receptor, mineralocorticoid receptor and peroxisome proliferator-activated receptor / Interações dos receptores nucleares com seus ligantes: Estudos estruturais do receptor de hormônio tireoidiano, do receptor de mineralocorticóide e do receptor ativado por proliferadores peroxissomais
Nuclear receptors are a superfamily of hormone-regulated transcriptional factors. This superfamily includes, for example, the receptor for thyroid hormone, estrogen, androgen, gluco and mineralocorticoid. In this work, we used structural biology and bioinformatic tools to study the interactions between some members of the nuclear receptor superfamily and its

10. Sistemas de acasalamento com defesa territorial : evolução, regras das disputas e seleção de territorios em satirineos neotropicais / Mating systems with territorial defense : evolution, contest rules and territory selection in neotropical satyrine Butterflies
Territorial conflicts in flying insects may be resolved through many different ways. In male butterflies, size, age and motivation are often reported as important determinants of the winning chances. However, the rules used when fighting, the biological context that affects the intensity of agonistic behaviors, and the functional role of male traits in the c

11. Ecology of interactions between Coragyps atratus (Bechstein, 1793) and Caracara plancus (Miller,JF, 1777) in regions of Uberlândia - MG / Ecologia de interações entre Coragyps atratus (Bechstein, 1793) e Caracara plancus (Miller, 1777) no município de Uberlândia (MG)
Although seldom reported, necrophagy is a relatively common phenomenon in nature. Among necrophagous vertebrates, scavengers are the only ones who have a diet composed almost exclusively by carrion. There are five species of scavengers recorded in Brazil and in some Brazilian regions these species can live in sympatry, interacting with each other and with sp

12. Comportamento do peixe-boi (Trichechus manatus manatus) nos oceanÃrios de ItamaracÃ: manejo e condiÃÃes abiÃticas
The aim of this study was to observe and describe the behavior of marine manatees, kept in captivity for rehabilitation and further release on their natural environment. To define the behavior pattern of these animals, their affiliate courtship activities and agonistic conducts were observed, verifying the presence of associations among group members, during
