Remating and sperm competition in replicate populations of Drosophila melanogaster adapted to alternative environments.

open access: yesPLoS ONE, 2014
The prevalence of sexual conflict in nature, as well as the supposedly arbitrary direction of the resulting coevolutionary trajectories, suggests that it may be an important driver of phenotypic divergence even in a constant environment. However, natural

Assessing the Need and Receptivity for an Integrated Healthy Sexual and Dating Relationships Intervention for Community College Students [PDF]

open access: yes, 2017
Background: In emerging adulthood, youth often become involved in more serious romantic relationships. However, many lack the skills to avoid an unplanned pregnancy or sexually transmitted infection (STI), and to ensure a healthy dating relationship ...

Security, peace and development: Unpacking discursive constructions of wartime rape and sexual violence in Syria [PDF]

open access: yes, 2018
The ‘rape-as-a-weapon’ of war narrative has been particularly influential in the securitization of sexual violence. Drawing upon ideas about the fetishization of Conflict-Related Sexual Violence (CRSV) (Meger 2016a, 2016b), this article unpacks the ...

Sex-specific influence of communal breeding experience on parenting performance and fitness in a burying beetle

open access: yesRoyal Society Open Science, 2022
Communal breeding, wherein multiple conspecifics live and reproduce together, may generate short-term benefits in terms of defence and reproduction. However, its carry-over effects remain unclear. We experimentally tested the effects of communal breeding

Effects of social stimuli on sleep in mice: non-rapid-eye-movement (NREM) sleep is promoted by aggressive interaction but not by sexual interaction [PDF]

open access: yes, 2001
Sleep is generally considered to be a process of recovery from prior wakefulness. In addition to being affected by the duration of the waking period, sleep architecture and sleep EEG also depend on the quality of wakefulness.

Experimental evidence that group size generates divergent benefits of cooperative breeding for male and female ostriches

open access: yeseLife, 2022
Cooperative breeding allows the costs of parental care to be shared, but as groups become larger, such benefits often decline as competition increases and group cohesion breaks down.

Transcriptomes of parents identify parenting strategies and sexual conflict in a subsocial beetle [PDF]

open access: yes, 2015
This work was funded by UK NERC grants to M.G.R. and A.J.M. an NERC studentship to D.J.P. the University of Georgia and a US NSF grant to A.J.M. and M.G.R.Parenting in the burying beetle Nicrophorus vespilloides is complex and, unusually, the sex and ...

Reproductive Isolation through Experimental Manipulation of Sexually Antagonistic Coevolution in Drosophila melanogaster

open access: yesScientific Reports, 2017
Promiscuity can drive the evolution of sexual conflict before and after mating occurs. Post mating, the male ejaculate can selfishly manipulate female physiology, leading to a chemical arms race between the sexes.

Sexual Conflict: Mechanisms and Emerging Themes in Resistance Biology [PDF]

open access: yes, 2018
Sexual conflict is acknowledged as pervasive, with the potential to generate and maintain genetic variation. Mechanistic studies of conflict have been important in providing direct evidence for the existence of sexual conflict.

Genomic Signatures of Sexual Conflict [PDF]

open access: yesJournal of Heredity, 2017
Sexual conflict is a specific class of intergenomic conflict that describes the reciprocal sex-specific fitness costs generated by antagonistic reproductive interactions. The potential for sexual conflict is an inherent property of having a shared genome between the sexes and, therefore, is an extreme form of an environment-dependent fitness effect. In
