Individual‐based analyses reveal effects of behavioral and demographic variables associated with multi‐annual reproductive success of male and female lake sturgeon

open access: yesEcology and Evolution, 2023
Quantifying effects of individual attributes and population demographic characteristics that affect inter‐ and intrasexual interactions and adult reproductive success, and the spatial and temporal contexts in which they are expressed is important to ...

Broodstock History Strongly Influences Natural Spawning Success in Hatchery Steelhead (Oncorhynchus mykiss). [PDF]

open access: yesPLoS ONE, 2016
We used genetic parentage analysis of 6200 potential parents and 5497 juvenile offspring to evaluate the relative reproductive success of hatchery and natural steelhead (Onchorhynchus mykiss) when spawning in the wild between 2008 and 2011 in the ...

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

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

Determinants and long‐term costs of early reproduction in males of a long‐lived polygynous mammal

open access: yesEcology and Evolution, 2021
In long‐lived polygynous species, male reproductive success is often monopolized by a few mature dominant individuals. Young males are generally too small to be dominant and may employ alternative tactics; however, little is known about the determinants ...

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

open access: yesRoyal 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

open access: yesScientific 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 ...

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

open access: yesGlobal 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

Influence of Early Reproductive Success on Longevity and Late Reproductive Success in an Alpine Ungulate [PDF]

open access: yesThe American Naturalist, 2017
The life-history theories of aging predict lifetime trade-offs between early reproductive allocation and late-life survival, reproduction, or both components of fitness. Recent studies in wild populations have found evidence for these early-late life trade-offs, but rarely have they been found across multiple traits while exploring the additional ...

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]

open access: yesPLoS 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

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.
