Sexual conflict over phenological traits: selection for protandry can lock populations into temporally mismatched reproduction.

Publication Type: Academic Journal

Source(s): Evolution; international journal of organic evolution [Evolution] 2023 Mar 01; Vol. 77 (3), pp. 789-800.

Authors:

Abstract: In seasonal environments, competition among males can drive males to emerge before females. Females, simultaneously, should avoid emerging at times after sufficient male availability. We show that the consequent sexual conflict over timing traits can p...

Ornaments are equally informative in male and female birds.

Publication Type: Academic Journal

Source(s): Nature communications [Nat Commun] 2022 Oct 07; Vol. 13 (1), pp. 5917. Date of Electronic Publication: 2022 Oct 07.

Abstract: Female ornaments are often reduced, male-like traits. Although these were long perceived as non-functional, it is now broadly accepted that female ornaments can be adaptive. However, it is unclear whether this is as common in females as it is in males,...

Transcriptomic responses of females to consumption of nuptial food gifts as a potential mediator of sexual conflict in decorated crickets.

Publication Type: Academic Journal

Source(s): Journal of evolutionary biology [J Evol Biol] 2023 Jan; Vol. 36 (1), pp. 183-194. Date of Electronic Publication: 2022 Nov 10.

Abstract: Nuptial food gift provisioning by males to females at mating is a strategy in many insects that is thought to be shaped by sexual conflict or sexual selection, as it affords males access to a female's physiology. While males often attempt to use these ...

An approximate line attractor in the hypothalamus encodes an aggressive state.

Publication Type: Academic Journal

Source(s): Cell [Cell] 2023 Jan 05; Vol. 186 (1), pp. 178-193.e15.

Abstract: The hypothalamus regulates innate social behaviors, including mating and aggression. These behaviors can be evoked by optogenetic stimulation of specific neuronal subpopulations within MPOA and VMHvl, respectively. Here, we perform dynamical systems mo...

Pre- and post-copulatory sexual selection increase offspring quality but impose survival costs to female field crickets.

Publication Type: Academic Journal

Source(s): Journal of evolutionary biology [J Evol Biol] 2023 Jan; Vol. 36 (1), pp. 296-308. Date of Electronic Publication: 2022 Dec 09.

Abstract: Whether sexual selection increases or decreases fitness is under ongoing debate. Sexual selection operates before and after mating. Yet, the effects of each episode of selection on individual reproductive success remain largely unexplored. We ask how d...

Effects of early social experience on sexual behavior in Japanese quail (Coturnix Japonica).

Publication Type: Academic Journal

Source(s): Learning & behavior [Learn Behav] 2022 Sep; Vol. 50 (3), pp. 283-297. Date of Electronic Publication: 2022 May 23.

Abstract: Experiences during immature phases of development, especially social experiences with individuals of the opposite sex, have implications for adult sexual behavior. Nevertheless, whether and how early experience can affect sexual learning in adulthood i...

Behavioral, Neural, and Molecular Mechanisms of Conditioned Mate Preference: The Role of Opioids and First Experiences of Sexual Reward.

Publication Type: Academic Journal

Source(s): International journal of molecular sciences [Int J Mol Sci] 2022 Aug 10; Vol. 23 (16). Date of Electronic Publication: 2022 Aug 10.

Abstract: Although mechanisms of mate preference are thought to be relatively hard-wired, experience with appetitive and consummatory sexual reward has been shown to condition preferences for partner related cues and even objects that predict sexual reward. Here...

Lekking as collective behaviour.

Publication Type: Academic Journal

Source(s): Philosophical transactions of the Royal Society of London. Series B, Biological sciences [Philos Trans R Soc Lond B Biol Sci] 2023 Apr 10; Vol. 378 (1874), pp. 20220066. Date of Electronic Publication: 2023 Feb 20.

Abstract: Lekking is a spectacular mating system in which males maintain tightly organized clustering of territories during the mating season, and females visit these leks for mating. Various hypotheses-ranging from predation dilution to mate choice and mating b...

The Role of Atypical Sexual Preference and Behavior in Neuroelectrophysiological Research of Human Sexual Behavior.

Publication Type: Academic Journal

Source(s): Archives of sexual behavior [Arch Sex Behav] 2023 Feb; Vol. 52 (2), pp. 607-610. Date of Electronic Publication: 2021 Feb 11.

Disentangling the causes of temporal variation in the opportunity for sexual selection.

Publication Type: Academic Journal

Source(s): Nature communications [Nat Commun] 2023 Feb 22; Vol. 14 (1), pp. 1006. Date of Electronic Publication: 2023 Feb 22.

Abstract: In principle, temporal fluctuations in the potential for sexual selection can be estimated as changes in intrasexual variance in reproductive success (i.e. the opportunity for selection). However, we know little about how opportunity measures vary over...
