Male‐biased sexual selection, but not sexual dichromatism, predicts speciation in birds
Sexual selection is thought to shape phylogenetic diversity by affecting speciation or extinction rates. However, the net effect of sexual selection on diversification is hard to predict because many of the hypothesized effects on speciation or ...

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

Can sexual selection drive female life histories? A comparative study on Galliform birds [PDF]
Sexual selection has been identified as a major evolutionary force shaping male life history traits but its impact on female life history evolution is less clear.

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 ...

Sexual selection and sex allocation in a simultaneous hermaphrodite [PDF]
Since Darwin’s pioneering work, sexual selection theory has become a unifying framework in evolutionary biology successfully explaining the variation in sexual dimorphism, reproductive strategies and mating systems. Although, it has long been argued that

Sexual Selection and Sexual Dimorphism in Mottled Sculpins [PDF]
There are two aspects to sexual selection (Darwin, 1871). Intra-sexual selection focuses on the consequences of competition between members of one sex (usually males) for access to the other sex; whereas epigamic selection or female choice focuses on the consequences of mate preferences of one sex (usually females) with regard to the other sex ...

Sexual selection protects against extinction [PDF]
Reproduction through sex carries substantial costs, mainly because only half of sexual adults produce offspring1. It has been theorized that these costs could be countered if sex allows sexual selection to clear the universal fitness constraint of ...

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.

Genetic polymorphism can be maintained over time by negative frequency-dependent (FD) selection induced by Rock-paper-scissors (RPS) social systems. RPS games produce cyclic dynamics, and have been suggested to exist in lizards, insects, isopods, plants,
