Intelligence and Fitness: The Mediating Role of Educational Level
Evolutionary Psychology, 2017 The evolutionary status of intelligence is not clear: It is positively related to various indicators of fitness but negatively to reproductive success as the most important fitness marker.

Ecology and Evolution, 2021 Mating systems and patterns of reproductive success in fishes play an important role in ecology and evolution. While information on the reproductive ecology of many anadromous salmonids (Oncorhynchus spp.) is well detailed, there is less information for ...

Love Influences Reproductive Success in Humans
Frontiers in Psychology, 2017 As love seems to be universal, researchers have attempted to find its biological basis. However, no studies till date have shown its direct association with reproductive success, which is broadly known to be a good measure of fitness. Here, we show links

Serial monogamy benefits both sexes in the biparental convict cichlid [PDF]
PeerJ, 2019 Monogamy can be either long-term or serial, with new pairs formed with each breeding bout. Costs and benefits are associated with each strategy. Because biparental convict cichlids (Amatitlania nigrofasciata) typically switch mates, exhibiting serial ...

Phyllosphere microbial associations improve plant reproductive success
Frontiers in Plant Science, 2023 The above-ground (phyllosphere) plant microbiome is increasingly recognized as an important component of plant health. We hypothesized that phyllosphere bacterial recruitment may be disrupted in a greenhouse setting, and that adding a bacterial amendment

Sex‐dependent effects of parental age on offspring fitness in a cooperatively breeding bird
Evolution Letters, 2022 Parental age can have considerable effects on offspring phenotypes and health. However, intergenerational effects may also have longer term effects on offspring fitness.

Lifetime Reproductive Success and Heritability in Nature
The American Naturalist, 2000 The observation that traits closely related to fitness ("fitness traits") have lower heritabilities than traits more distantly associated with fitness has traditionally been framed in terms of Fisher's fundamental theorem of natural selection-fitness traits are expected to have low levels of additive genetic variance due to rapid fixation of alleles ...
