Selecting habitat to what purpose? The advantage of exploring the habitat–fitness relationship

open access: yesEcosphere, 2017
Measures of reproductive success have been recognized in many fields as essential tools to assess the status of populations, species, and communities. However, difficulties in gathering data on reproductive success often prevent researchers from taking ...

Intelligence and Fitness: The Mediating Role of Educational Level

open access: yesEvolutionary 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.

Mating systems and predictors of relative reproductive success in a Cutthroat Trout subspecies of conservation concern

open access: yesEcology 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

open access: yesFrontiers 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

Sex‐dependent effects of parental age on offspring fitness in a cooperatively breeding bird

open access: yesEvolution 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.

Phyllosphere microbial associations improve plant reproductive success

open access: yesFrontiers 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

Serial monogamy benefits both sexes in the biparental convict cichlid [PDF]

open access: yesPeerJ, 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 ...

Lifetime Reproductive Success and Heritability in Nature

open access: yesThe 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 ...

Evaluation of a reproductive index for estimating songbird productivity: Case study of the golden‐cheeked warbler

open access: yesWildlife Society Bulletin, 2015
It is critically important to determine and understand relationships between endangered species populations and landscape and habitat features to effectively manage and conserve populations and the habitats they rely on. Several recent studies focused on

Genetic evidence for the mating system and reproductive success of black sea bream (Acanthopagrus schlegelii)

open access: yesEcology and Evolution, 2020
Understanding the mating system and reproductive success of a species provides evidence for sexual selection. We examined the mating system and the reproductive success of captive adult black sea bream (Acanthopagrus schlegelii), using parentage ...
