Stress responses are essential for survival, coordinating behavioural, physiological and molecular adjustments that enable organisms to cope with challenges. Most research has focused on vertebrates, leaving invertebrate stress physiology comparatively underexplored, particularly in insects. In this review, we compare insect and vertebrate stress responses to examine what insects reveal about the [...]
Social decision-making in a freshwater gastropod
Published: 2026-10-09
Subjects: Animal Studies, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Social and Behavioral Sciences
Animals are hypothesized to plastically adjust their social behaviour expression dependent on their environment and their phenotype to ensure that its benefits outweigh its costs. There is a strong research bias towards socially complex vertebrates and eusocial insects. Thus, here we study mollusks, a taxon whose social behaviour is less well studied. As predation is one of the strongest drivers [...]
Foraging group size affects repeatable individual variation and strategic social plasticity
Published: 2026-09-22
Subjects: Animal Studies, Ecology and Evolutionary Biology, Life Sciences
Although game theory successfully predicts how negative frequency dependence can maintain behavioural variation through stable equilibria, it does not predict whether this variation reflects repeatable differences among individuals or variation within individuals. Because social group size influences how individuals respond to social information, it may shape how individual variation is [...]
As invasions slow down, biosecurity must move inward
Published: 2026-09-21
Subjects: Animal Studies, Biology, Ecology and Evolutionary Biology, Environmental Studies
Rates of non-native-species first records and establishment are slowing. This is encouraging, but it changes rather than resolves the biosecurity problem imposed by biological invasions. As external establishments decline while national non-native-species pools remain compositionally distinct, a growing share of remaining invasion opportunity should lie in redistribution among connected [...]
Nest architecture as overlooked material culture: the case for systematic study of construction behaviour across nest-building primates
Published: 2026-06-10
Subjects: Animal Studies, Anthropology, Biological Psychology, Biology, Comparative Psychology, Ecology and Evolutionary Biology
Frans de Waal's work highlighted an uncomfortable question: not whether animals have complex cognitive lives, but why we are so reluctant to recognise them. Nest building in great apes is perhaps the most striking example of this problem. Every great ape builds a nest, every day, for the entirety of its adult life. The behaviour has been documented ecologically for decades. Yet the internal [...]
Extending the open-source R package {spatsoc} with measures of intragroup social dynamics identified by a scoping review
Published: 2026-04-30
Subjects: Animal Studies, Behavior and Ethology, Ecology and Evolutionary Biology, Software Engineering
Beyond proximity-based social networks and home range overlap, animal telemetry data can also be used to measure intragroup social dynamics including individual position within groups, individual and group level movement directions, leadership patterns and lagged follower behaviours. We used a scoping review of literature across domains, including behavioural ecology, collective movement, and [...]
Standardizing turn-taking metrics: A methodological toolkit for data annotation across species and taxa
Published: 2026-03-27
Subjects: Animal Studies, Communication, Social and Behavioral Sciences
Conversational turn-taking, the cooperative reciprocal exchange of short and flexible turns, is fundamental for communication and social coordination. Initially thought to be uniquely human, recent research showed some evidence of cooperative turn-taking also in other animal species. However, systematic evaluations and comparisons of turn-taking skills within and across species pose considerable [...]
Towards a better understanding of adaptation: Problem description, partial solutions, and recommendations

This paper is the product of an international workshop aiming to make progress in our general understanding of adaptation. We met from 5-7 February 2025 in Hannover (Germany), funded by the foundation “Volkswagen Stiftung”. For our group of theoretical and empirical biologists, social scientists, and philosophers of science we set up a program to facilitate communication and collaboration between [...]
Personality tips the scale: How individual differences in exploration shape behavioural and hormonal adjustment to different environments
Published: 2026-01-07
Subjects: Animal Sciences, Animal Studies, Life Sciences, Social and Behavioral Sciences
Individuals show consistent differences in their behaviour across time and/or context, usually referred to as animal personality in behavioural ecology. These inter-individual differences raised the question if animals of different personalities also vary in how they adjust to certain environmental conditions. In the present study, we aimed to investigate personality-dependent adjustments to [...]
Behavioural repertoire and the onset of precocious sexual behaviours in juvenile ruffs (Calidris pugnax)
Published: 2025-12-10
Subjects: Animal Studies, Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Life Sciences
Adult phenotypes are shaped by developmental processes during early life. This also applies to reproduction and dominance-related behaviours before maturation, called precocious sexual behaviours. However, beyond largely anecdotal reports, the onset of such behaviours is rarely studied. Here we document the development of precocious sexual behaviours in the ruff Calidris pugnax, a lekking [...]
Cultural practices and food subsidies shape the architecture of multispecies coexistence in a tropical megacity
Published: 2025-11-03
Subjects: Animal Studies, Behavior and Ethology, Biodiversity, Community-based Research, Human Ecology, Ornithology, Other Animal Sciences, Population Biology, Urban Studies and Planning, Zoology
1. Multispecies relationships among people and nature in tropical cities are increasingly shaped by pervasive waste systems, against the backdrop of changing cultural practices and infrastructure. But human–animal conflict is often managed through reactive, species-specific interventions that overlook the social-ecological processes producing urban coexistence. We examined how cultural practices [...]
Women's Role in Elasmobranch Fishery in Indonesia
Published: 2025-09-29
Subjects: Animal Studies, Environmental Studies, Social and Behavioral Sciences, Sociology
Women play a significant role in the fisheries chain, particularly in trade and processing, yet they are still not adequately acknowledged. Indonesia is the world's largest shark fishing country, with an average annual production exceeding 100,000 tons. The shark fishery, on its right, is a controversial and often misunderstood topic, not to mention the involvement of vulnerable groups in the [...]
Observation methods in animal behaviour: a simulation study of performance
Published: 2025-08-22
Subjects: Animal Studies, Biological Psychology, Social and Behavioral Sciences
Most behavioural studies rely on systematic samples of behaviour, as observing and recording all behavioural events that occur is rarely feasible. Choosing an observation method involves several key decisions, including which individuals to observe, how to sample their behaviour, and how to distribute sampling effort over time. These decisions influence how closely behavioural estimates reflect [...]
Behavioural tactics across thermal gradients align with partial morphological divergence in brook charr
Published: 2025-07-15
Subjects: Animal Studies, Aquaculture and Fisheries Life Sciences
Understanding how animals balance environmental constraints is essential for predicting species persistence under climate change. In thermally stratified lakes, cold-water fishes such as brook charr (Salvelinus fontinalis) must navigate vertical gradients in temperature and oxygen to optimize foraging while avoiding physiological stress. We hypothesized that individuals would exhibit behavioral [...]
How cooperation drove the evolution of vocal production learning in hominins
Published: 2025-06-16
Subjects: Animal Studies, Anthropology, Behavior and Ethology, Evolution
Language evolved uniquely in the hominin lineage. Critical to its evolution was the emergence of vocal production learning (VPL), the ability to acquire novel vocalizations. The mechanisms underlying VPL have been extensively studied across taxa and are convergent with hominins. However, the drivers of hominin VPL are still unknown. Reviewing the various functions of VPL across taxa, we propose [...]
