DOI: 10.1007/s10164-021-00726-x
Abstract: Sexual selection favors the evolution of pre-copulatory sexual traits such as ornamentation and post-copulatory sexual traits such as long sperm, but the interrelationships of the two types of sexual traits remain unclear. Here, using Japanese… read more here.

Within-population variation in the chemistry of life: the stoichiometry of sexual dimorphism in multiple dimensions

DOI: 10.1007/s10682-017-9900-9
Abstract: In sexual species, phenotypic divergence between males and females, or sexual dimorphism, is often the source of the most staggering examples of phenotypic variation in nature. Theory suggests that exaggerated sexual traits should drive sex-specific… read more here.

DOI: 10.1007/s10682-018-9964-1
Abstract: AbstractThe rapid diversification of sexual traits is a common phenomenon accompanying the evolution of reproductive isolation, yet the evolutionary mechanisms driving such diversification are often unknown. Based on experimentally evolved strains of two sister species… read more here.

DOI: 10.1016/j.jcz.2020.05.009
Abstract: Abstract Based on a quantitative mathematical revolution, the study of morphology has had an important emphasis by developing statistical shape analysis. This made possible the combination of multivariate statistical methods and new ways to visualize… read more here.

Resource-dependent investment in male sexual traits in a viviparous fish

DOI: 10.1093/beheco/arac060
Abstract: Abstract Exaggerated and conspicuous sexually selected traits are often costly to produce and maintain. Costly traits are expected to show resource-dependent expression, since limited resources prevent animals from investing maximally in multiple traits simultaneously. However,… read more here.

Early life and transgenerational stressors impact secondary sexual traits and fitness

DOI: 10.1093/beheco/arz020
Abstract: Developmental stress from early life challenges impacts adult phenotype across a range of species. However, the potential transgenerational consequences for adult phenotype are largely unknown. Additionally, the possible impacts of natural hatch/birth order and natal… read more here.

Effect of population density on relationship between pre- and postcopulatory sexual traits
Sign Up to like & getrecommendations! Published in 2019 at "Animal Biology"
DOI: 10.1163/15707563-20181057
Abstract: Sexual selection theory states that the premating (ornaments and armaments) sexual traits should trade off with the postmating (testes and ejaculates) sexual traits, assuming that growing and maintaining these traits is expensive and that total… read more here.
