Abstract: Abstract Research on sexual selection and hybridization has focused on female mate choice and male–male competition. While the evolutionary outcomes of interspecific female preference have been well explored, we are now gaining a better understanding… read more here.

Abstract: Mammal sex allocation research has focused almost exclusively on maternal traits, but it is now apparent that fathers can also influence offspring sex ratios. Parents that produce female offspring under conditions of intense male–male competition… read more here.

Abstract: Intrasexual selection occurs in male‐male competition over access to females and usually results in the larger male winning. While much research has documented that size matters, little is known about how the larger male wins.… read more here.

DOI: 10.2108/zs180110
Abstract: In some species, male traits are more exaggerated than female traits. To understand the evolution and maintenance of such male traits, it is important to clarify their function in contexts of both intra- and intersexual… read more here.
