“…It has been demonstrated that in Hetaerina, the size of the pigmented area of the wings is under selection, mainly with respect to male-male agonistic displays (Grether 1996a, Serrano-Meneses et al 2007. The size of these pigmented areas are positively correlated with thoracic fat reserves (Contreras-Garduño et al 2006, SerranoMeneses et al 2007, Contreras-Garduño et al 2008, which are used as fuel to light (Marden & Waage 1990). Our results showed that males with a larger pigmented area won more contests, independently of body size (but see also Serrano-Meneses et al 2007).…”

Current evidence suggests that in Hetaerina damsel lies males exhibit lek mating system. In this study, in order to answer if the same occurs in Hetaerina rosea Selys, we manipulated vegetation substrates used as territories and quanti ied the number of visiting females, males defending territories and ight intensity. We also examined whether body size and wing pigmentation are selectable traits in male-male competition, and if age affects male territorial behavior. Our results showed that males with larger pigmented areas won more contests, independently of body size. Old males changed from territoriality to sneaking strategy. Contrary to other Hetaerina species, males of H. rosea do not display lek behavior, but defend resources according to the resource defense polygyny strategy.

“…Resident animals fight more strongly for territories that provide higher benefits of shelter, food and nest sites, to name a few, than for territories with less benefits (Alcock, 2005;Tizo-Pedroso & Del-Claro, 2007;Contreras-Garduno et al, 2008). Nijman & Heuts (2000) showed that resident fish (including the cichlid, H. burtoni) win more fights, and become the dominant fish, more frequently when reared in an enriched environment, absent of greater aggressiveness.…”

Environmental enrichment reduces aggression of pearl cichlid, Geophagus brasiliensis, during resident-intruder interactions

Among fishes, when residents and intruders fight, residents usually win, most likely because they value the residence more than intruders. We hypothesized that enriched environments increase the value of an area in dispute, causing a resident to more fiercely defend a resource-rich environment than a poor one. However, in the present study, intruder-resident tests with the pearl cichlid, Geophagus brasiliensis, showed environmental enrichment actually reduces aggression and can even lead to co-habitation without fighting. Additionally, in our experiments, the prior residence effect occurred irrespective of enrichment condition. Decreased visibility from increased habitat complexity reduces interactions between fish and consequently might explain the lower aggression observed herein.Em lutas entre peixes residentes e intrusos, residentes geralmente vencem, provavelmente porque valorizam o território mais do que os intrusos. Nós aventamos a hipótese de que ambientes enriquecidos aumentam o valor da área em disputa, levando os residentes a defenderem mais violentamente ambientes enriquecidos de recursos do que ambientes empobrecidos, pois possuiriam mais motivação para mantê-lo. No entanto, no presente estudo, ao testarmos as interações entre intrusos e residentes em acarás, Geophagus brasiliensis, observamos que o enriquecimento ambiental reduz a agressividade e pode levar a cohabitação entre os peixes, sem luta. Adicionalmente, em nossos experimentos, o efeito da residência prévia ocorreu independente da condição de enriquecimento. A diminuição das interações entre os peixes e, consequentemente, a diminuição do nível de agressividade é aqui atribuída aos efeitos da diminuição da visibilidade entre os peixes devido ao aumento de complexidade do ambiente.

“…For sizeindependent values of flight muscles, we used the standardized residuals from a linear regression between thoracic muscle mass and total dry body mass. This value (also called flight muscle ratio, FMR) is frequently used as an estimator of maneuverability capacity during aerial interactions in insects (Marden and Chai 1991;Marden and Rollins 1994;Contreras-Garduño et al 2008). …”

Although many studies have evaluated the possible rules used by males to settle territorial contests, few have simultaneously considered the possibility of mutual or self-assessment of fighting ability and the effect of prior residence on the chances of winning. Here, we experimentally investigated the influence of previous residency on the development and outcome of contests between males of the butterfly Hermeuptychia fallax. By comparing the frequency of resident victories in nonmanipulated disputes versus interactions in which both rivals were induced to behave as residents, we showed that prior residency may interact with body mass in contest resolution. In nonmanipulated disputes, resident males showed high winning probabilities, although they were similar to losers in body mass. However, when both males behaved as residents, the disputes were longer and were settled in favor of the heavier male. This indicates that, although residency is an important component of male willingness to fight, it is not the only factor influencing conflict resolution. Despite the correlation between body mass and territorial success, the weight of neither winners nor losers correlated with fighting duration. We conclude that residence asymmetry may sometimes conceal male traits important to contest resolution and that it may obscure the identification of the assessment strategy used in contests.
