1. 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),

2. 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

3. Seleção intra-sexual na libélula Homeoura nepos (Zygoptera: Coenagrionidae): conflito sexual e sistema de acasalamento
O dimorfismo sexual, as interações agonísticas e o tipo de associação de machos com suas parceiras sexuais são características submetidas a pressões seletivas que podem determinar o tipo de sistema de acasalamento de uma espécie. Em Odonata, dois tipos de sistemas de acasalamento predominam: a poliginia por defesa de recursos e a poliginia por scram

4. Why do winners keep winning? Androgen mediation of winner but not loser effects in cichlid fish
Animal conflicts are influenced by social experience such that a previous winning experience increases the probability of winning the next agonistic interaction, whereas a previous losing experience has the opposite effect. Since androgens respond to social interactions, increasing in winners and decreasing in losers, we hypothesized that socially induced tr
