Cognition in contests: mechanisms, ecology, and evolution
MS Reichert, JL Quinn - Trends in ecology & evolution, 2017 - cell.com
Animal contests govern access to key resources and are a fundamental determinant of
fitness within populations. Little is known about the mechanisms generating individual …

Do hormone manipulations reduce fitness? A meta-analytic test of the Optimal Endocrine Phenotype Hypothesis
Endocrine traits (eg, circulating hormone concentrations, receptor expression) can vary
considerably among individuals within populations. Here, we develop two evolutionary …

Environmental and genetic determinants of innovativeness in a natural population of birds
Much of the evidence for the idea that individuals differ in their propensity to innovate and
solve new problems has come from studies on captive primates. Increasingly, behavioural …

Inbreeding and cognition in wild populations: a relationship that remains unnoticed
I Gavriilidi, L Van Linden - Oikos, 2024 - Wiley Online Library
Anthropogenic activities are causing a steep decline of wildlife populations. Increased
inbreeding in shrinking populations can substantially curb individual fitness and population …

Environmental variability, the value of information, and learning in winter residents
Cognitive processes related to the collection, storage and use of information (eg learning,
memory) contribute to reducing uncertainty about the environment and can thus be key to …

Developmental stress impairs performance on an association task in male and female songbirds, but impairs auditory learning in females only
TM Farrell, A Morgan, SA MacDougall-Shackleton - Animal cognition, 2016 - Springer
In songbirds, early-life environments critically shape song development. Many studies have
demonstrated that developmental stress impairs song learning and the development of song …
