Retrospective Analysis of Habitat Selection by Boreal Caribou in the Prince Albert Greater Ecosystem, Saskatchewan, Canada
Published: 2026-07-22
Subjects: Behavior and Ethology
Recent caribou research in Saskatchewan has focused on faecal DNA analyses, which provide valuable information on caribou population size and connectivity but limited information on habitat use and selection. The delineation of Caribou Habitat Management Areas (CHMAs) and associated tiered management objectives are based in part on habitat potential mapping derived from an expert-based model. [...]
Quiet stewardship and deer return times: sound continuity, not fuel, predicts white-tailed deer avoidance of stewardship machines in a multi-year steward-conducted camera census
Published: 2026-07-18
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Recreation and routine land management can alter wildlife behavior even where they do not reduce abundance, and the acoustic component of human activity is difficult to isolate from human presence itself. Within a single restored prairie–savanna, the same trail network is worked on foot, on a silent electric utility vehicle (UTV), and behind gas engines (a gas ATV and a mower), with all vehicle [...]
Phantom decoys cause irrational choice in lizards
Published: 2026-07-14
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology
Choice theory generally predicts that individuals act to maximize their benefits and behave according to simple rationality assumptions. However, the predictions of choice theory are often violated when an additional option is added to a choice set leading to a shift in choice between the original options. While this “decoy effect” has been documented across several animal taxa, it has not been [...]
From a review to the field: Alternative coping styles under urbanisation
Published: 2026-07-06
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Endocrinology, Life Sciences, Other Ecology and Evolutionary Biology, Physiology, Population Biology, Systems and Integrative Physiology Life Sciences, Zoology
Under human-induced rapid environmental changes, behavioural and physiological responses of organisms are key to maintain homeostasis and minimise fitness loss. Both responses can be integrated, into among-individual correlations forming stress-coping styles or syndromes (SCS). Such SCS emerge from genetic correlations or adaptive trade-offs. In the context of environmental challenges, more [...]
Bridging nutritional geometry and network ecology to quantify the robustness of nutritional networks
Published: 2026-07-01
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Nutrition, Other Ecology and Evolutionary Biology, Research Methods in Life Sciences
Understanding the robustness and resilience of ecological networks is key to managing ecosystems and mitigating biodiversity loss. Simple models of network robustness simulate species losses across ecological networks but lack physiological realism, asserting that species persist if they interact with another organism. This neglects the nutritional consequences of resource loss and nutrition as a [...]
An individual-based model for white storks (Ciconia ciconia) in Germany during breeding season
Published: 2026-06-26
Subjects: Behavior and Ethology, Biodiversity, Ornithology
Understanding how habitat selection influences individual fitness is essential for predicting species responses to environmental change. Resource Selection Functions (RSFs) are widely used to quantify habitat preferences, but they often overlook individual variation and rarely link habitat use to demographic outcomes. We combined empirical habitat-selection modelling with a spatially explicit [...]
Natural history models of bird–building collisions
Published: 2026-06-25
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Building collisions kill an estimated 1.28–5.19 billion birds annually in North America, making them the second leading cause of human-related avian mortality. Yet the behavioral and ecological drivers of collisions remain difficult to disentangle, as most knowledge derives from carcass surveys rather than direct observations. Here, we propose a conceptual framework that synthesizes four natural [...]
Beyond mistakes: same-sex partner acceptance and broad mating filters coexist in termite pairing
Published: 2026-06-24
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Entomology, Evolution
Same-sex sexual behavior is often interpreted either as a mistake arising from indiscriminate attempts or as an adaptive behavior directed towards same-sex partners. These explanations are typically considered mutually exclusive. Here we challenge this assumption using an adaptive same-sex pairing system in Reticulitermes termites. Long-term male-male pairings originate from tandem running, in [...]
Visual-chemotactic saltatory search in Octopus hummelincki (Mollusca, Cephalopoda): a case study in the South Atlantic
Published: 2026-06-23
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
We report for the first time evidence of foraging by Octopus hummelincki and analyze it using saltatory search theory, which posits alternating phases of locomotion and stationary search. Our data showed that substrate complexity dictates behavioral transitions: locomotion predominated in sand, whereas solid substrates elicited tactile exploration. The move-to-search scaling ratio (0.63) aligns [...]
An integrated framework for unifying our understanding of nonconsumptive predation risk effects
Published: 2026-06-12
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Integrative Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Predation risk can induce risk-induced trait responses (RITRs) – changes in prey defensive traits including behavior, morphology, life history, and physiology – thought to have profound effects on prey fitness and population dynamics (termed ‘nonconsumptive effects’). Yet, predicting the magnitude of RITRs and their fitness consequences remains difficult because outcomes depend heavily on [...]
Modelling habitat selection using tracking data from central place foraging species: A practical guide for ecologists
Published: 2026-06-04
Subjects: Applied Statistics, Behavior and Ethology, Biostatistics, Ecology and Evolutionary Biology, Natural Resources and Conservation, Other Ecology and Evolutionary Biology, Research Methods in Life Sciences, Statistical Methodology, Statistical Models
The study of habitat selection has long been at the heart of ecological research and is critical to deciphering the mechanisms that govern species’ responses to global change. This is particularly important for central place foraging species, whose ability to adapt to shifting environmental conditions and anthropogenic disturbance is limited by persistent attachment to a fixed site. Recent [...]
Gradual development and chance beget individuality
Published: 2026-06-02
Subjects: Behavior and Ethology, Developmental Biology, Ecology and Evolutionary Biology, Evolution
Behaviors – and thus behavioral individuality – rarely emerge fully formed but are instead built gradually through development, shaped by processes involving learning, skill formation, and experience. Prevailing theory in behavioral ecology, however, has largely focused on static equilibrium outcomes where behaviors are analyzed only as fully formed traits, often neglecting development. Here, we [...]
Evaluating the potential of molecular dietary analysis of predators for the detection of emerging plant pests
Published: 2026-06-01
Subjects: Agriculture, Behavior and Ethology, Biodiversity, Biosecurity, Ecology and Evolutionary Biology, Entomology, Forest Biology, Forest Management, Forest Sciences, Genetics, Laboratory and Basic Science Research Life Sciences, Life Sciences, Research Methods in Life Sciences
Monitoring plant pests is crucial for maximising yields across agricultural and forest production systems, but also for the mitigation of invasive species spread. Traditional monitoring methods, such as mass trapping and direct observation, scale poorly and introduce latency between collection, detection and response. Since many plant pests are frequently consumed by predators, molecular dietary [...]
The coevolution of cooperation and socially-mediated dispersal: a model
Published: 2026-06-01
Subjects: Behavior and Ethology, Evolution, Population Biology
Limited dispersal can promote the evolution of cooperation by increasing relatedness between social partners. However it also intensifies kin competition, potentially cancelling the benefits of helping. Here, we analyse a model in which individuals evolve both (i) the probability of cooperating within social groups as adults, and (ii) the dispersal probability of juveniles conditional on the [...]
Methodological choices influence ecological inference in passive acoustic monitoring of a Neotropical nightjar
Published: 2026-05-30
Subjects: Behavior and Ethology, Biodiversity, Population Biology
Passive acoustic monitoring is increasingly used to investigate species activity and habitat use through occupancy analyses. Yet, the complex analytical workflow, from automated detector choice to confidence thresholds and statistical modeling framework, is amongst the factors that influence ecological inference, and the extent these decisions affect modelling outputs is poorly debated. Here, we [...]
