Population Change in a Marine Bird Colony is Driven By Changes in Recruitment

Avian Conservation and Ecology, 2011
The population dynamics of long-lived birds are thought to be very sensitive to changes in adult survival. However, where natal philopatry is low, recruitment from the larger metapopulation may have the strongest effect on population growth rate even in

Finding a Mate With No Social Skills

, 2015
Sexual reproductive behavior has a necessary social coordination component as willing and capable partners must both be in the right place at the right time.

Autumn Migration of Mississippi Flyway Mallards as Determined by Satellite Telemetry [PDF]

, 2012
We used satellite telemetry to study autumn migration timing, routes, stopover duration, and final destinations of mallards Anas platyrhynchos captured the previous spring in Arkansas from 2004 to 2007.

Survival and divergence in a small group: The extraordinary genomic history of the endangered Apennine brown bear stragglers [PDF]

, 2017
About 100 km east of Rome, in the central Apennine Mountains, a critically endangered population of ∼50 brown bears live in complete isolation. Mating outside this population is prevented by several 100 km of bear-free territories.

Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

Journal of Animal Ecology, EarlyView.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Does frugivory in Citharexylum solanaceum (Verbenaceae) drive nomadism in the Ipanema bat Pygoderma bilabiatum (Chiroptera: Phyllostomidae)?

Zoologia (Curitiba), 2018
Neotropical bats are recognized as effective seed dispersers, especially of small-seeded pioneer plants during early stages of forest regeneration. There had been few reports on the ecology of the bat Pygoderma bilabiatum (Wagner, 1843), which appears to

Trade‐offs across life history stages and social association types shape winter communal roosting in a long‐lived raptor

Journal of Animal Ecology, EarlyView.
Our study demonstrates how life history trade‐offs and pair bonds influence winter roosting in red kites. Analysing long‐term GPS data from 216 individuals, we reveal marked behavioural plasticity in communal roosting: young, non‐breeding males are most likely to join communal roosts, whereas breeding pairs predominantly roost together near their ...

Stabilization and optimization of host-microbe-environment interactions as a potential reason for the behavior of natal philopatry

Animal Microbiome, 2021
Many animals engage in a behavior known as natal philopatry, where after sexual maturity they return to their own birthplaces for subsequent reproduction.

How sex-biased dispersal affects conflict over parental investment [PDF]

, 2016
This article is a preprint and has not been peer-reviewed. It is availble from bioRxiv via the DOI in this record.Existing models of parental investment have mainly focused on interactions at the level of the family, and have paid much less attention to

Early‐life stasis in partial seasonal migration is underpinned by among‐cohort variation in migratory plasticity and selective disappearance

Journal of Animal Ecology, EarlyView.
Changes to mean early‐life phenotypes are fundamentally driven by joint dynamics of plasticity and selection, but such effects are rarely quantified. We show that cross‐cohort stasis in the degree of partial migration is underpinned by substantial within‐ and among‐cohort variation in plasticity and selection on migration, indicating high environmental
