No relationship between fecundity and annual reproductive rate in bony fish [PDF]

open access: yes, 2004
Background. There is still a widespread notion that bony fishes with high fecundities are more productive and therefore more resistant to overexploitation.

Pheromones that correlate with reproductive success in competitive conditions

open access: yesScientific Reports, 2021
The major urinary proteins (MUPs) of house mice (Mus musculus) bind and stabilize the release of pheromones and other volatile organic compounds (VOCs) from urinary scent marks, which mediate chemical communication.

The contribution of differential hatching success to the fitness of species and interspecific hybrids [PDF]

open access: yes, 2007
Resting egg banks of microcrustaceans have been used to reconstruct the evolutionary and ecological history of species. However, recent studies provided evidence for a discrepancy between dormant propagules in the sediment and the planktonic population ...

Intersexual conflict influences female reproductive success in a female-dispersing primate [PDF]

open access: yes, 2019
In group-living mammals, individual efforts to maximize reproductive success result in conflicts and compromises between the sexes. Females utilize counterstrategies to minimize the costs of sexual coercion by males, but few studies have examined the ...

Plant Fertilization: Maximizing Reproductive Success [PDF]

open access: yesCurrent Biology, 2012
Sperm competition does not occur in flowering plants as typically only a single pair of sperm cells is delivered for double fertilization. Two recent reports show that plants are capable of avoiding reproductive failure when defective sperm cells are released.

Postnatal depression and reproductive success in modern, low-fertility contexts [PDF]

open access: yes, 2015
Background and objectives: Postnatal depression (PND) presents a puzzling phenomenon to evolutionary anthropologists as it is highly prevalent and yet detrimental to child development and maternal health.

Inflorescence stem grafting made easy in Arabidopsis [PDF]

open access: yes, 2016
UNLABELLED BACKGROUND Plant grafting techniques have deepened our understanding of the signals facilitating communication between the root and shoot, as well as between shoot and reproductive organs.

Colony size predicts division of labour in Attine ants [PDF]

open access: yes, 2014
Division of labour is central to the ecological success of eusocial insects, yet the evolutionary factors driving increases in complexity in division of labour are little known.

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.
