“…Among various possible explanations, two are particularly relevant here, one non-adaptive and one adaptive (Angilletta, Steury, & Sears, 2004 We found evidence for cross-generational paternal effects, as temperature experienced by fathers impacted on both hatching success and offspring fitness. This adds to the small but growing body of evidence on the prevalence of paternal effects (Crean et al, 2013;Evans et al, 2017;Zajitschek, Zajitschek, & Manier, 2017;Zajitschek et al, 2014). Males exposed to a high temperature as adults produced offspring with lower survival compared to their low-temperature treated conspecifics.…”

Temperature thereby also has the potential to affect offspring fitness, as recently documented for other environmentally-induced changes in sperm phenotype, such as variation in social environment and diet (Crean & Bonduriansky, 2014;Evans, Lymbery, Wiid, Rahman, & Gasparini, 2017;Marshall, 2015).…”

Global rising of average temperatures and increase in extreme climatic events may largely impact animal survival and reproduction. Yet, how variation in temperature may affect male fertility, in particular ejaculate traits, and whether this can in turn affect offspring fitness, is seldom addressed. Paternal effects may be of key importance as they could impact the rate and direction of evolutionary change in response to climate change. We tested the effects of temperature experienced by males on sperm traits, and asked whether the paternal environmental temperature affected offspring phenotype. We further explored the potential for paternal effects to be adaptive, which would occur when offspring fitness increased under the same environmental conditions experienced by the fathers. We exposed male field crickets to high or low temperatures at two life stages, either throughout development or as adults, and tested sperm traits (number and quality) and offspring fitness (hatching success and survival). We further assessed sperm traits in offspring, after they had also been exposed to the same or different temperature experienced by their father. We found that temperature affected sperm traits depending on the life‐stage of individuals. When the exposure was given during adulthood, males exposed to high temperature produced less sperm and of lower quality compared to males exposed to lower temperature, while if exposure was given during development, males exposed to high temperature produced more sperm and of better quality compared to males exposed to low temperatures. Offspring fitness was significantly affected by paternal temperature, evidence for anticipatory paternal effects on sperm traits was not found. Our study indicates that temperature can mediate cross‐generational effects, and that paternal effects may be mediated by changes in temperature and therefore much more widespread in nature than previously assumed.

“…The state or condition of individuals can affect mating effort, mating preferences, attractiveness to others, gamete quality, and ultimately reproductive success (Bakker et al 1999;Hebets et al 2008;Schultzhaus et al 2017;Evans et al 2017). An individual's overall condition is influenced by factors including, but not limited to, diet (e.g.…”

Mate choice in most organisms is not random, but determined by a suite of interacting traits and environmental factors. While the selective pressures underlying differences in mate choice between species, populations, individuals and even within individuals has been gaining interest, there still remains unexplained variation in mate preferences especially in non-model systems. Despite being of social, environmental and economic importance there is comparatively little known about how salmonids and other tetraploids make mate choice decisions in the wild and the resultant reproductive success (i.e. the number of offspring which survive to sexual maturity). Resolving questions related to salmonid mate choice is of particular importance given that humans have been supplementing salmon populations through aquaculture for decades. Despite these efforts, hatchery produced fish have lower reproductive success relative to their wild counterparts and salmon populations are declining. Most studies on mate choice and reproductive success in salmonids focus on body size and major histocompatibility complex based choice. However, mate choice can also be affected by other factors including other genetic factors, predation risk and social environment. Here, we (a) synthesize what is presently known about mate choice and reproductive success in salmonids, (b) identify gaps in knowledge and areas where there is a lack of consensus in results, and (c) suggest interdisciplinary ways of advancing our understanding of mate choice in salmonids and other polyploids.

Mounting evidence suggests that nongenetic paternal effects on offspring may be widespread among animal taxa, but the mechanisms underlying this form of nongenetic inheritance are not yet fully understood. Here, we show that seminal fluids underlie paternal effects on early offspring survival in an insect, the cricket Teleogryllus oceanicus, and quantify the contribution of this paternal effect to the inheritance of this important fitness trait. We used castrated males within a full‐sib half‐sib experimental design to show that seminal fluid donors were responsible for variation in the survival of developing embryos to hatching, and in their subsequent survival to adulthood. Increased expression of two seminal fluid protein genes, previously found to be positively associated with sperm quality, was found to be negatively associated with embryo survival. These nongenetic paternal effects hold important implications for the evolution of adaptive maternal responses to sperm competition, and more broadly for the interpretation of sire effects from classic quantitative genetic breeding designs.
