Divergent pollination system and morph-dependent effects of corolla length on inaccuracy of reciprocity and reproductive success of a distylous species of Rubiaceae

Acta Botânica Brasílica, 2021
Intraspecific floral variations may affect the degree of generalization and efficacy of pollinators, with consequences for plant reproductive success.

Precipitation during two weeks in spring influences reproductive success of first-year females in the long-lived Natterer's bat

Royal Society Open Science, 2022
Bats are characterized by low reproductive rates in contrast with most of other small mammals. This makes their populations vulnerable when inclement environmental conditions such as cold and rainy weather impair the reproductive success of females.

Temporal changes in reproductive success and optimal breeding decisions in a long-distance migratory bird

Scientific Reports, 2020
Many avian migrants have not adjusted breeding phenology to climate warming resulting in negative consequences for their offspring. We studied seasonal changes in reproductive success of the greater snow goose (Anser caerulescens atlantica), a long ...

Indirect routes to reproductive success

eLife, 2012
By comparing wild-type and transgenic tobacco plants in a natural ecosystem, researchers have confirmed that the indirect defence mechanisms employed by plants to fend off herbivorous insects can increase Darwinian fitness.

Using drones and citizen science counts to track colonial waterbird breeding, an indicator for ecosystem health on the Chobe River, Botswana

Global Ecology and Conservation, 2022
Many of the world’s freshwater ecosystems are degrading with increasing water resource developments, necessitating identification of useful indicators that track large scale environmental change. We investigated the effectiveness of waterbird breeding at

Endoparasite infection has both short- and long-term negative effects on reproductive success of female house sparrows, as revealed by faecal parasitic egg counts. [PDF]

PLoS ONE, 2015
Parasites have the potential to severely reduce host reproductive success. However, the effects of endoparasites on reproductive success have not received the same amount of attention as the effects of parasites on host survival.

Pheromones that correlate with reproductive success in competitive conditions

Scientific 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.

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

Ecosphere, 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 ...

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

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 ...

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.
