The effect of sex, age, and boldness on inhibitory control
Published: 2025-03-03
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Inhibitory control requires an individual to suppress impulsive actions in favour of more appropriate behaviours to gain a delayed reward. It plays an important role in activities such as foraging and initiating mating, but high within-species variation suggests that some individuals have greater inhibitory control than others. A standard index of inhibitory control used in many taxa is measuring [...]
There is no such thing as an herbivore: incidental and intentional ingestion profoundly affects both herbivores and plant-dwelling invertebrates.
Published: 2025-02-26
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology
Real-life ‘herbivores’ are not the herbivores of our simplistic ecological and behavioral models – real-life herbivores constantly consume other organisms both incidentally and intentionally, with the ‘prey’ usually consisting of plant-dwelling arthropods, smaller invertebrates, and carrion. A remarkable amount of disparate literature has amassed on these phenomena, yet the implications of these [...]
A new perspective on Squamate social cognition – the use of semiochemicals
Published: 2025-02-07
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences
The Social Intelligence Hypothesis suggests that cognition might be key to enable animals to live in social groups. Especially social cognition is important as it allows animals to respond appropriately to conspecifics and ensure group cohesion. Social cognition is extensively studied in mammals and birds but to gain a broad understanding of the benefits of social cognitive processes in social [...]
Reproductive consequences of mate retention and divorce in a short-lived migratory passerine
Published: 2025-01-16
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
In socially monogamous birds, pair bond duration varies widely across species, from single-breeding associations to long-lasting, multi-year bonds. Studies on mate retention and divorce have predominantly focused on long-lived species, while research in short-lived and migratory species is limited. Consequently, the fitness consequences of divorce or remating in these species remain unclear. [...]
Does post-natal parental care influence cognitive development in a social gecko?
Published: 2025-01-06
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences
How cognition evolved remains a debated “hot-topic” in the field of animal cognition. Current hypotheses link variation in sociality, ecology, and more generally, environmental challenges to differences in cognitive development, both between as well as within species. Research supporting the Social Intelligence Hypothesis, which states that cognition evolved to deal with social challenges, is [...]
Dynamic parental roles revealed by fine-scale hunting behaviour with concurrent pair tracking in the wild
Published: 2024-12-23
Subjects: Behavior and Ethology, Life Sciences, Ornithology, Zoology
Parental cooperation in offspring care is essential for offspring survival in species with extended biparental care. Yet, the mechanisms through which each parent’s foraging skills and performance shape both their own and their partner’s contributions to offspring rearing, particularly in natural conditions, remain poorly understood. Using high-resolution GPS and accelerometer data, we [...]
Reduced levels of relatedness indicate that great-tailed grackles disperse further at the edge of their range
Published: 2024-12-19
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Population Biology
It is generally thought that behavioral flexibility, the ability to change behavior when circumstances change, plays an important role in the ability of a species to rapidly expand their geographic range. To expand into new areas, individuals might specifically show flexibility in dispersal behavior, their movement away from their parents to where they themselves reproduce. Great-tailed grackles [...]
Synthesis of nature’s extravaganza: an augmented meta-meta-analysis on (putative) sexual signals
Published: 2024-12-06
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution
Conspicuous traits that do not seem to contribute to the survival of their bearers, such as colourful body parts and bizarre behaviours, have puzzled biologists for centuries. Sexual selection theory posits that these traits evolved because more conspicuous individuals attract more mates and experience greater fitness, yet evidence for this remains fragmented. Our augmented meta-meta-analysis of [...]
Individual foraging specialization and success change with experience in a virtual predator-prey system
Published: 2024-11-27
Subjects: Behavior and Ethology, Biodiversity, Ecology and Evolutionary Biology
The capacity of predators to match their tactic to their prey and to optimize their skills at implementing a given tactic are expected to drive the outcome of predator-prey interactions. Hence, successive interactions of predators with their prey may result in increased flexibility in tactic use or in individual foraging specialization. Yet, there are limited empirical assessments showing links [...]
The Influence of Light Colour on the Behaviour of Atlantic Cod in an Experimental Setting
Published: 2024-11-15
Subjects: Behavior and Ethology, Marine Biology
Fishing technologies often exploit the visual sensitivity of target species to alter their behaviours. Atlantic cod (Gadus morhua Linnaeus, 1758) are an economically important species, commonly targeted by fisheries in the North Atlantic, yet the behaviour of adult Atlantic cod in reaction to the simultaneous presentation of various light stimuli has not been assessed in an isolated setting to [...]
Advancing the spatiotemporal dimension of wildlife–pollution interactions

Chemical pollution is a pervasive problem and is now considered the fastest-growing agent of global environmental change. Numerous pollutants are known to disrupt animal behaviour, alter ecological interactions, and shift evolutionary trajectories. Crucially, both chemical pollutants and individual organisms are non-randomly distributed throughout the environment. Despite this, the current [...]
Choosing friends in an uncertain world: information reduces relationship stability in a Bayesian learning model of cooperative partnership
Published: 2024-11-14
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Social animals often form differentiated social relationships with conspecifics. Developing closer partnerships with some than others can facilitate cooperative interactions in which individuals share resources or risk. When choosing a partner, individuals face a decision: a known partner might be sub-optimal if better options are available, but switching partners can be risky if others' [...]
Social bonds between non-kin are common, but less stable, in a mixed-related society
Published: 2024-11-13
Subjects: Behavior and Ethology
Members of social groups often form social relationships, which can carry important fitness benefits. Kin selection predicts that these relationships should be prevalent between kin, yet there is increasing evidence that, in societies that feature a mixture of related and unrelated individuals, social relationships exist between non-kin of the same sex. Nevertheless, quantitative research on [...]

Behavioral flexibility is related to exploration, but not boldness, persistence or motor diversity
Published: 2024-11-09
Subjects: Behavior and Ethology, Life Sciences
Behavioral flexibility, the ability to change behavior when circumstances change based on learning from previous experience, is thought to play an important role in a species' ability to successfully adapt to new environments and expand its geographic range. However, behavioral flexibility is rarely directly tested at the individual level. This limits our ability to determine how it relates to [...]
