Anthropogenic nesting substrates increase parental fitness in a Neotropical songbird, the pale‐breasted thrush Turdus leucomelas

open access: yesJournal of Avian Biology
The failure of breeding attempts is a major hindrance to bird reproduction, making nest site choice under strong selective pressure. Urbanization may offer lower risk of nest predation to certain bird species, but the impact of using anthropogenic ...

Data from: Host nest site choice depends on risk of cuckoo parasitism in magpie hosts

open access: yes, 2017
Avian brood parasites impose large fitness costs on their hosts and, thus, brood parasitism has selected for an array of host defensive mechanisms to avoid them.

Autoclaving Nest-Material Remains Influences the Probability of Ectoparasitism of Nestling Hoopoes (Upupa epops) [PDF]

open access: yes, 2020
Microorganisms may have direct negative effects on their animal hosts and cause diseases, but some others provide animals with protection against infections, parasites, and even predators. However, parasites or predators might take their cue from odors

Early‐Life Telomere Length Negatively Covaries With Brood Size and Father Age, and Predicts Long‐Term Survival in Male Barn Swallows (Hirundo rustica)

open access: yesIntegrative Zoology, EarlyView.
In barn swallows, nestlings raised in larger broods or by older social fathers have shorter telomeres, and those with longer telomeres tend to live longer, suggesting that early‐life conditions may shape individual lifespan through telomere dynamics. ABSTRACT Parental decisions on breeding, such as brood size and timing of reproduction, influence the ...

Birds build camouflaged nests [PDF]

open access: yes, 2014
This work was supported by the Biotechnology and Biological Sciences Research Council (BBSRC) (BB/I019502/1 to S.D.H. and S.L.M.) and by Roslin Institute Strategic Grant funding from the BBSRC (to S.L.M).It is assumed that many birds attempt to conceal ...

Hidden Losses: Assessing the Risk of Coextinction Among Ectoparasitic Flies and Their Bat Host Species in Brazil

open access: yesAnimal Conservation, EarlyView.
The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).

A game-theoretic model of interspecific brood parasitism with sequential decisions [PDF]

open access: yes, 2008
The interaction between hosts and parasites in bird populations has been studied extensively. This paper uses game-theoretic methods to model this interaction.

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks

open access: yesAgricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Volatiles of symbiotic bacterial origin explain ectoparasitism and fledging success of hoopoes

open access: yesAnimal Microbiome
Background Some parasites use olfactory cues to detect their hosts and, since bacterial symbionts are partially responsible for animal odours, they could influence host parasitism.

Nest usurpation by a common eider toward a long-tailed duck

open access: yesPolar Research, 2016
Intraspecific and non-obligate brood parasitism and nest takeover is well documented in common eiders (Somateria mollissima borealis) nesting in the Arctic. However, we report the takeover of a long-tailed duck (Clangula hyemalis) nest by a female common
