Sexual dimorphism in bite performance drives morphological variation in chameleons [PDF]
, 2014 Phenotypic performance in different environments is central to understanding the evolutionary and ecological processes that drive adaptive divergence and, ultimately, speciation.

Current Biology, 2011 Sexual selection is a concept that has probably been misunderstood and misrepresented more than any other idea in evolutionary biology, confusion that continues to the present day. We are not entirely sure why this is, but sexual politics seems to have played its role, as does a failure to understand what sexual selection is and why it was initially ...

No evidence of male-biased sexual selection in a snake with conventional Darwinian sex roles [PDF]
Royal Society Open Science, 2020 Decades of research on sexual selection have demonstrated that ‘conventional’ Darwinian sex roles are common in species with anisogamous gametes, with those species often exhibiting male-biased sexual selection. Yet, mating system characteristics such as

Cascading effects of pre-adult survival on sexual selection
Royal Society Open Science, 2022 Sexual selection influences broad-scale patterns of biodiversity. While a large body of research has investigated the effect of mate competition on sexual selection, less work has examined how pre-adult life history influences sexual selection. We used a

Female fertile phase synchrony, and male mating and reproductive skew, in the crested macaque
Scientific Reports, 2021 High social status is the primary determinant of reproductive success among group-living male mammals. Primates living in multimale–multifemale groups show the greatest variation in the strength of this link, with marked variation in reproductive skew by

Stronger net selection on males across animals
eLife, 2021 Sexual selection is considered the major driver for the evolution of sex differences. However, the eco-evolutionary dynamics of sexual selection and their role for a population’s adaptive potential to respond to environmental change have only recently ...

Genomic Insights Into the Molecular Basis of Sexual Selection in Birds
Frontiers in Ecology and Evolution, 2021 Sexual selection is a well-known biological process, yet the genomic basis and patterns of sexual selection are not fully understood. The extravagant ornamental plumage of peacock (Pavo cristatus) was instrumental in shaping Charles Darwin's theory of ...

The impact of small groups on pre‐ and postcopulatory sexual selection in polyandrous populations
Ecology and Evolution, 2023 Sexual selection is a key evolutionary force but varies widely between populations. Two key factors that influence sexual selection are the extent to which females copulate with multiple males (polyandry) and variation in the social environment ...

Frontiers in Ecology and Evolution, 2021 Charles Darwin published his second book “Sexual selection and the descent of man” in 1871 150 years ago, to try to explain, amongst other things, the evolution of the peacock’s train, something that he famously thought was problematic for his theory of ...

Identification of Follower Status Based on Male Proximity Score in Crested Macaque
Hayati Journal of Biosciences, 2020 Crested macaque live in multimale-multifemale social groups where temporary association (consortship) typically occurs. Current theory and these limited qualitative observations suggest the hypothesis that behavior functions as a means for males to gain ...
