Do individuals in better condition survive for longer? Field survival estimates according to male alternative reproductive tactics and sex.

摘要: There is a gap in terms of the supposed survival differences recorded field according to individual condition. This partly due our inability assess wild. Here we applied modern statistical techniques field-gathered data two damselfly species whose males practice alternative reproductive tactics (ARTs) and indicators condition both sexes are known. In Paraphlebia zoe, there ART: larger black-winged (BW) male which defends mating territories smaller hyaline-winged (HW) that usually acts as satellite. this species, morphs correlated with body size. Calopteryx haemorrhoidalis, follow their better practicing territorial ART. addition, correlates positively wing pigmentation sexes. Our prediction for was tactic will survive less longer than using nonterritorial tactic, or more pigmented animals longer. P. BW survived females but did not differ from HW males, necessarily individuals fact, size affected only when group identity analysed, showing positive relationship slightly negative morphs. For C. females, good predictor. results partially confirm assumptions based on maintenance ARTs. also indicate female pigmentation, fitness component – proposed by recent sexual selection ideas females.
