Calibrating exchange-level claims about sperm whale codas against surrogates: overlap, ornamentation and rubato under independent pre-registered control
Published: 2026-09-15
Subjects: Behavior and Ethology, Marine Biology
Sharma et al. (Nat. Commun. 15:3617, 2024) report that sperm whale codas carry a combinatorial "phonetic alphabet" built from four dimensions, two of which — rubato (smooth modulation of coda duration across an exchange) and ornamentation (an extra click marking sequence edges) — are properties of coda sequences rather than of codas. Sequence-level claims presuppose a model of the exchange [...]
Relational acoustic geometry of over 20,000 common nightingale strophes: a framework for continuous vocal analysis
Published: 2026-09-15
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Ornithology
Large collections of complex animal vocalizations are often organized through predefined song categories, which provide powerful descriptive units but do not directly characterize continuous and representation-dependent relationships within the acoustic material. This study presents a field-grounded framework for examining such relationships without assigning vocalizations to categories in [...]
Behavioural strategy and predator control: a coupled evolutionary predator-prey model for kiwi conservation in New Zealand
Published: 2026-09-11
Subjects: Applied Mathematics, Behavior and Ethology, Dynamic Systems, Ecology and Evolutionary Biology, Life Sciences, Physical Sciences and Mathematics, Population Biology
Conservation management of endangered species can be enhanced by quantitative frameworks that simultaneously model behavioural adaptations alongside population dynamics. This paper presents a Coupled Evolutionary Predator-Prey Model (CEPPM) that integrates replicator dynamics from Evolutionary Game Theory with an extended Lotka-Volterra predator-prey framework, applied to kiwi (Apteryx spp.) [...]
Moose on the loose: personality-driven space use and activity in a large, free-roaming cervid
Published: 2026-09-10
Subjects: Animal Sciences, Behavior and Ethology, Zoology
Background Animal personality (i.e., consistent inter individual behavioural and physiological differences that are repeatable over time and across contexts) has important implications for ecological processes, yet remains poorly studied in large herbivores such as cervids. Methods In this study, we investigated personality and the occurrence of a behavioural syndrome in 33 free ranging female [...]
Suction or filter feeder? Morphology supports a combined feeding mechanism in the Little Auk (Alle alle)
Published: 2026-09-09
Subjects: Behavior and Ethology, Life Sciences, Ornithology
Little Auks (Alle alle) are the most abundant seabird in the Arctic, with their largest colonies in north-west Greenland sustained by foraging nearly exclusively on plankton. Given their high metabolic demands, adults must capture an approximate 60,000 copepods per day, raising long-standing questions about how this can be achieved efficiently, and with this, questions about the anatomical basis [...]
Comparing space use behavior and aviary-based exploration measures in a species rapidly expanding its geographic range
Published: 2026-09-08
Subjects: Behavior and Ethology, Integrative Biology, Life Sciences
Species range expansions could be facilitated by consistent behavioral differences between individuals on the range edge relative to those in other parts of the range. Movement behaviors in particular are thought to be important for expanding and invasive species. There is evidence for a relationship between consistent individual differences in exploratory behavior and dispersal (the permanent [...]
Social transmission of fear is disrupted by pharmaceutical pollution
Published: 2026-09-04
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology
Social information transfer enables rapid responses to threats and underpins collective predator avoidance across taxa. Yet whether the growing threat of environmental pollutants, such as pharmaceuticals, disrupt this process remains unknown. Here, we show that the widespread antidepressant pollutant amitriptyline disrupts fear contagion—the automatic matching of an individual’s behavioural state [...]
Sex-specific divergence in microhabitat use and activity patterns in fire salamanders: temperature matters
Published: 2026-09-01
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Zoology
Human-driven climate change and habitat degradation cause alterations in the spatial and temporal availability of natural resources, forcing wildlife to adjust their interactions with the environment in order to survive. To identify changes and promote effective conservation measures within the limited suitable habitats available, it is crucial to better understand habitat use. Activity patterns [...]
The Defensive Repertoire of New World Coral Snakes: Evolution and Natural History
Published: 2026-08-21
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution
The defensive repertoire of New World coral snakes is diverse, but its evolutionary history remains poorly understood. We compiled 280 records of 11 defensive behaviors across 85 species of Micrurus and one species of Micruroides from the literature and contributions by researchers, naturalists, and wildlife photographers. Fifty-seven records represented behaviors not previously documented for [...]
Wolf–Deer Camera-trap Detections Across Wisconsin’s Statewide Wolf Range (2018–2025): A Temporary Increase in Wolves Following Deer After the 2021 Wolf Harvest, Displacement Effects by Habitat Zone, and Avoidance of People Across Co-occurring Species
Published: 2026-08-19
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Two prior analyses of wolf-enriched extracts of the Snapshot Wisconsin camera network — one county, then five northwestern counties — showed that gray wolves (Canis lupus) tended to arrive at cameras shortly after white-tailed deer (Odocoileus virginianus), that they arrived after antlered bucks more often than the bucks’ numbers would predict, and that deer returned to a site more slowly after a [...]
Mate choice copying in non-human animals: an update of two meta-analyses
Published: 2026-08-14
Subjects: Behavior and Ethology
Mate choice copying, the use of social information from the mating decisions of others, is a taxonomically widespread form of social learning with the potential to shape sexual selection. Two meta-analyses concluded that social information moderately and positively biases mate choice, but both rest on literature searches now at least seven years old. Using a multilingual, [...]
Wolf–Deer Movement After the 2021 Wolf Harvest, by North-South Gradient and Proximity to Towns using a Five-County Camera Record (2018–2025)
Published: 2026-08-03
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Previous analysis of a wolf-enriched extract of the Snapshot Wisconsin camera network for five northwestern counties (Barron, Burnett, Bayfield, Douglas, and Sawyer; 525 cameras, 294,031 camera-days, 634,214 detections, 2018–2025; 1,856 wolf detections on 197 cameras) established patterns in the way gray wolves (Canis lupus) follow, select which class of deer to follow, and how strongly they [...]
A modeling lens on landscapes-of-peril and other ecological drivers of zoonoses
Published: 2026-07-31
Subjects: Animal Diseases, Behavior and Ethology, Life Sciences
Ecological systems are driven by a complex suite of environmental conditions, interactions among individuals, and reciprocal behavioral and biological responses of organisms to the ecosystems they inhabit. Individuals may, in turn, reshape those systems, generating feedback that alters the ecological drivers influencing subsequent system dynamics. Extractive and competitive processes are embedded [...]
Patterns of Gray Wolf and White-tailed Deer Movement: Local, County and Regional Camera-trap Data (2018-2025)
Published: 2026-07-31
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
The gray wolf (Canis lupus) is the apex predator of white-tailed deer (Odocoileus virginianus), but on a single restored site it can be too rare to study. A year-round survey of about ten cameras at nine fixed stations on an approximately 100-ha prairie–savanna complex located within Washburn County, Wisconsin, yielded too few wolf detections over three years (11,473 animal detections, 2024–2026) [...]
