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 the conceptual and empirical framework for estimating genetic benefits of
mate choice, stressing that benefits must be measured from offspring
fitness because there are no unequivocal surrogates for genetic quality
of individuals or for compatibility of parents. We detail the relationship between genetic benefits and additive and nonadditive genetic variance in fitness, showing that the benefits have been overestimated in previous verbal treatments. We point out that additive
benefits readily arise from nonadditive gene action and that the idea
of “heritable nonadditive benefits” is a misconception. We review
the empirical evidence of the magnitude of benefits of good genes
and compatible genes in animal populations, and we outline the
most promising future directions for empirical research on the genetic benefits of mate choice.

Do the benefits of polyandry scale with outbreeding?
Burdfield-Steel, Emily; Auty, Sam; Shuker, David M. (Oxford University Press; International Society for Behavioral Ecology, 2015)There have been many potential explanations put forward as to why polyandry often persists despite the multiple costs it can inflict on females. One such explanation is avoidance of costs associated with mating with ... -
Silent Rain : Does the atmosphere-mediated connectivity between microbiomes influence bacterial evolutionary rates?
Jalasvuori, Matti (Oxford University Press, 2020)Air carries a vast number of bacteria and viruses over great distances all the time. This leads into the continuous introduction of foreign genetic material to local established microbial communities. In this perspective, ... -

Volatility as an asset class : diversification benefits of adding VSTOXX futures to European multi-asset portfolios
Jaatinen, Jimi (2021)Previous research has suggested that cross correlations of different asset classes tend to increase during market downturns. This in turn leads investors to look for alterna- tive sources of diversification. Placing special ... -
