Phenology of scramble polygyny in a wild population of chrysomelid beetles: the opportunity for and the strength of sexual selection [corrected]. [PDF]

open access: yesPLoS ONE, 2012
Recent debate has highlighted the importance of estimating both the strength of sexual selection on phenotypic traits, and the opportunity for sexual selection.

Metapopulation structure modulates sexual antagonism

open access: yesEvolution Letters, 2021
Despite the far‐reaching evolutionary implications of sexual conflict, the effects of metapopulation structure, when populations are subdivided into several demes connected to some degree by migration, on sexual conflict dynamics are unknown.

Sexual Selection and Proteinaceous Diversity in the Femoral Gland Secretions of Lacertid Lizards

open access: yesDiversity, 2023
Sexual selection contributes to the diversity of chemical signals in various animal groups. Lizards are good model species to study how sexual selection shapes signal diversity, as they are a chemically oriented taxonomic group with different levels of ...

Sexual selection for males with beneficial mutations

open access: yesScientific Reports, 2022
Sexual selection is the process by which traits providing a mating advantage are favoured. Theoretical treatments of the evolution of sex by sexual selection propose that it operates by reducing the load of deleterious mutations.

Intralocus sexual conflict diminishes the benefits of sexual selection. [PDF]

open access: yesPLoS Biology, 2006
Evolution based on the benefits of acquiring "good genes" in sexual selection is only plausible with the reliable transmission of genetic quality from one generation to the next.

REPEATED FREEZE-THAW CYCLES BUT NOT SHORT-TERM STORAGE OF FECAL EXTRACTS AT AMBIENT TEMPERATURE INFLUENCE THE STABILITY OF STEROID METABOLITE LEVELS IN CRESTED MACAQUES

open access: yesJurnal Kedokteran Hewan, 2017
The objective of this study was to examine the effects of repeated freeze-thaw cycles and short-term storage of fecal extracts at ambient temperature on the stability of fecal glucocorticoid (fGCM) and estrogen metabolite (fEM) levels from crested ...

Interaction-Independent Sexual Selection and the Mechanisms of Sexual Selection [PDF]

open access: yesEvolution, 1998
Darwin identified explicitly two types of sexual selection, male contests (combat and displays) and female choice, and he devoted the overwhelming majority of his examples to traits that influence the outcome of these interactions. Subsequent treatments of sexual selection have emphasized the importance of intra- and intersexual interactions as sources

Endless forms of sexual selection [PDF]

open access: yesPeerJ, 2019
In recent years, the field of sexual selection has exploded, with advances in theoretical and empirical research complementing each other in exciting ways.

Sexual selection, environmental robustness, and evolutionary demography of maladapted populations: A test using experimental evolution in seed beetles

open access: yesEvolutionary Applications, 2019
Whether sexual selection impedes or aids adaptation has become an outstanding question in times of rapid environmental change and parallels the debate about how the evolution of individual traits impacts on population dynamics.
