1. Foraging behavior of two egg parasitoids exploiting chemical cues from the stink bug Piezodorus guildinii (Hemiptera: Pentatomidae)
Abstract: Several parasitoids attacking the same host may lead to competition. Adult parasitoids’ abilities to find, parasitize and defend hosts determine resource’s retention potential. In soybean, two egg parasitoid species, Telenomus podisi and Trissolcus urichi (Hymenoptera: Platygastridae), compete on the egg masses of Piezodorus guildinii (Hemipter

2. 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

3. EFFECT OF AUDITORY ENRICHMENT (MUSIC) IN PREGNANT SOWS WELFARE
ABSTRACT Studies have shown that the benefits from music can improve the welfare conditions of laboratory, pet and production animals. The study aimed to evaluate the influence of music (Antonio Lucio Vivaldi compositions) on behavior aspects (position, activity, stereotypes, social and agonistic behavior) and physiological responses (respiratory rate and re

5. Fos expression in the prefrontal cortex and mesencephalic dorsal raphe nucleus in lactating rats after social instigation
Females are often less aggressive than males, but they exhibit high levels of agonistic behavior against an intruder in the area of the nest during lactation. This behavior is referred to as maternal aggression. In rats, maternal aggressive behavior occurs more often from postpartum day 3 (PPD 3) to PPD 12. Social instigation is an experimental protocol used

6. 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

7. CaracterÃsticas morfo-fisiolÃgicas como determinantes da capacidade de manutenÃÃo de territÃrios em machos de Macrothemis imitans (Odonata: Libellulidae) / Morphological and physiological features as determining of the capacity of maintenance territories in males of Macrothemis imitans(Odonata: Libellulidae)
In many animal species, males fight for the possession of territories that increase their mating chances. The fighting behavior of males may range from conflicts without physical contact to disputes with injuries and possible deaths. There are three models aiming to explain the rules adopted by males to decide the winner of a contest: war of attrition (WOA),

By excluding potential competitors in this area through aggressive behavior, territorialist individuals ensure priority access to essential resources for their survival and reproduction. In anuran amphibians, territoriality has been mainly related to

10. Long-term male aggregations of Euglossa melanotricha moure (Hymenoptera: Apidae) on fern fronds Serpocaulon triseriale (Pteridophyta: Polypodiaceae)
A communal dormitory of male orchid bees, Euglossa melanotricha Moure, was monitored over a one-year period, when they passed the night in the fronds of a Serpocaulon triseriale (Polypodiaceae) fern. The bees used the same fronds continuously, moving to neighboring fronds as senescence set in. As many as 49 males were observed together on any one night, clin

11. 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

12. 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
