Kin selection on one hand, and gamete interactions in post-ejaculatory sexual selection on the other are two major research themes that have risen to prominence over the past half century and have simultaneously developed into central fields of research in evolutionary biology. There is a natural connection between the two: when gametes interact with each other, very commonly many of them originate from the same parent and are thus siblings. For example, sperm competition will almost always involve competition between sibling gametes even if the interacting parents are not related to each other. If parents are related to each other, the relatedness between gametes increases further. Here we discuss the relation between kin selection on one hand, and gamete competition, gamete limitation, local gamete competition, and the evolution of sex allocation on the other. To illustrate these topics, we present a novel model on sex allocation in simultaneous hermaphrodites under sperm limitation and limited, costly dispersal. We find that sperm limitation can significantly increase allocation into male function, but limited dispersal (and thus increased relatedness) does not alter sex allocation regardless of the presence of sperm limitation.

Postmating–prezygotic isolation between two allopatric populations of Drosophila montana: fertilisation success differs under sperm competition
Ala-Honkola, Outi; Ritchie, Michael G.; Veltsos, Paris (John Wiley & Sons Ltd., 2016)Postmating but prezygotic (PMPZ) interactions are increasingly recognized as a potentially important early‐stage barrier in the evolution of reproductive isolation. A recent study described a potential example between ... -

Competitive interactions are mediated in a sex-specific manner by arbuscular mycorrhiza in Antennaria dioica
Varga, Sandra; Vega-Frutis, Rocío; Kytöviita, Minna-Maarit (Wiley-Blackwell Publishing Ltd.; Deutsche Botanische Gesellschaft, 2017)Plants usually interact with other plants, and the outcome of such interaction ranges from facilitation to competition depending on the identity of the plants, including their sexual expression. Arbuscular mycorrhizal (AM) ... -

Multiple mechanisms of cryptic female choice act on intraspecific male variation in Drosophila simulans
Ala-Honkola, Outi; Manier, Mollie K. (Springer, 2016)Postcopulatory sexual selection can arise when females mate with multiple males and is usually mediated by an interaction between the sexes. Cryptic female choice (CFC) is one form of postcopulatory sexual selection that ...
