1. Let's talk about sex roles: what affects perceptions of sex differences in animal behaviour?

Author:

sexual selection,   etc   ; animals; males; mating behavior; surveys;     Show all 5 Subjects
Abstract:
... In the field of sexual selection, it is common to encounter the idea of ‘sex roles’: choosy and caring females and competitive and promiscuous males. Despite criticism of these stereotypes from some evolutionary biologists, sex roles still appear as a norm in much of the sexual selection-related literature. This may be because scientists anthropomorphize animal behaviours, which raises the questio ...

Abstract:
... Ornamental coloration is frequently an honest signal of quality associated with sexual selection. While changes in average environmental conditions affect carotenoid‐ and melanin‐based coloration, no evidence exists that changes in intrinsic environmental predictability affect coloration. Here we experimentally manipulated the intrinsic predictability of precipitation in semi‐natural populations o ...

Abstract:
... Birds are a remarkable example of how sexual selection can produce diverse ornaments and behaviours. Specialised fighting structures like deer's antlers, in contrast, are mostly absent among birds. Here, we investigated if the birds’ costly mode of locomotion—powered flight—helps explain the scarcity of weapons among members of this clade. Our simulations of flight energetics predicted that the co ...

Abstract:
... Ornamentation found in both sexes, or mutual ornamentation, can be used as a threat signal towards rivals or to bias aggression towards those sharing preferences for mates or other resources. The widespread male bias in ornamentation suggests that sexual selection for these competitive functions is stronger in males, but these functions are rarely compared between the sexes. We investigated intras ...

5. Does female resistance to mating select for live‐fast‐die‐young strategies in males? A comparative analysis in the genus Drosophila

sexual selection,   etc   ; Drosophila; females; longevity; males; phylogeny; sexual dimorphism; variance;     Show all 8 Subjects
Abstract:
... Female promiscuity is a pervasive selective force on male reproductive traits, and the strength of sexual selection is predicted to influence the trade‐off between lifespan and reproduction. In species where sexual selection is intense, males are predicted to invest in sexual strategies that shorten their lifespan, potentially resulting in female‐biased sexual dimorphism in longevity. However, com ...

Abstract:
... It has been proposed that blue‐green egg coloration is a condition‐dependent female sexual trait that may modify paternal care in a post‐mating sexual selection scenario. This pattern may arise because the pigment responsible for eggshell colouration (biliverdin) may be a costly and limited resource, whose availability is linked to female health state. Thus, it can be predicted that females whose ...

Abstract:
... Influential models of speciation by sexual selection posit either a single shared preference for a universal display, expressed only when males are locally adapted and hence in high condition, or that shared loci evolve population‐specific alleles for displays and preferences. However, many closely related species instead show substantial differences across categorically different traits. We prese ...

Abstract:
... Females usually encounter males sequentially and should discriminate between potential partners among the males that they encounter. Thus, appropriate sequential mating decisions allow females to gain mate choice benefits in the circumstance of multiple encounters. For example, if mated females can assess the genetic quality of a male prior to mating, they can remate with genetically superior male ...

Abstract:
... Species in Galliformes have elaborate ritual courtship displays, often including strutting, fluffing of tail or head feathers, and vocal sounds that serve as excellent examples of sexual selection. According to the male orientation to the female while either posturing or moving, these courtship displays of gallinaceous species can be classified into three categories: 1) ‘frontal displays’, 2) ‘lat ...

Abstract:
... Securing females is a crucial determinant of male fitness in many species. Mate-searching efficiency is often associated with increased mobility in males, but an increased investment in movement may reduce other fitness traits via potential trade-offs. In precopulatory sexual selection via female mate choice, the rate of encounter with females and the attractiveness of males are essential to incre ...

Abstract:
... Sexual selection theory has proven to be fundamental to our understanding of the male-female (sperm-egg) interactions that characterise fertilisation. However, sexual selection does not operate in a void and abiotic environmental factors have been shown to modulate the outcome of pre-copularory sexual interactions. Environmental modulation of post-copulatory interactions are particularly likely be ...

Abstract:
... Behavioural variation in courtship has become a central theme in the study of sexual selection. Courtship behaviour can vary consistently between males (between-individual variation) due to inherent characteristics of individuals, but males may also plastically adjust their courtship (within-individual variation) in response to the characteristics of the potential breeding mate or the environmenta ...

Abstract:
... A positive relationship of body size and sexual size dimorphism (males’ size relative to females), called Rensch’s rule, is often observed in comparisons within non-parasitic taxa. However, this allometric relationship has rarely been tested in comparisons across closely related parasite species. Since male sexual rivalry is often regarded as the main cause of this phenomenon, the present study te ...

We did so by comparing phonotaxis behaviors of female eastern g ...

Allowed to evolve unchecked, mate harming traits are predicted to bring down average fitness of a population, unless mitigated by the evolution of resistance in females. In addition, life history may also modulate sexual conflict, but the mechanism is not clearly understood. Here we investigated the ev ...
