Genetic benefits from mate choice could be attained by choosing mates with high heritable
quality (“good genes”) and that are genetically compatible (“compatible genes”). We clarify …

In natural fertilisation, the female reproductive tract allows only a strictly selected sperm
subpopulation to proceed in the vicinity of an unfertilised oocyte. Female-mediated sperm …

Research on mate choice has primarily focused on preferences for quality indicators,
assuming that all individuals show consensus about who is the most attractive. However, in …

Despite evidence that variation in male–female reproductive compatibility exists in many
fertilization systems, identifying mechanisms of cryptic female choice at the gamete level has …

Genomic tools are lacking for invasive and native populations of sea lamprey (Petromyzon
marinus). Our objective was to discover single nucleotide polymorphism (SNP) loci to …

This work aims to present an historical review of the ecosystem services provided by
anadromous fish (ie, species that migrate from the sea to the river to spawn) throughout …

Humans often mate with those resembling themselves, a phenomenon described as positive
assortative mating (PAM). The causes of this attract broad interest, but there is little …

The objective of the present experimental study was to gain a better understanding of the
foraging activity of Asellus aquaticus during fish egg incubation. A. aquaticus were …

In many socially monogamous species, females copulate with and produce offspring sired
by males other than their social mates, yet it remains controversial whether or how females …

Animals should decipher information about the genetic make‐up of conspecifics in order to
enhance the fitness benefits associated with mate choice. Although there is increasing …
