Animal behaviour is remarkably sensitive to disruption by chemical pollution, with widespread implications for ecological and evolutionary processes in contaminated wildlife populations. However, conventional approaches applied study the impacts of pollutants on seldom address complexity natural environments which contamination occurs. The aim this review guide rapidly developing field behavioural ecotoxicology towards increased environmental realism, complexity, mechanistic understanding. We identify research areas ecology that date have been largely overlooked within but promise yield valuable insights, including within- among-individual variation, social networks collective behaviour, multi-stressor interactions. Further, we feature methodological technological innovations enable collection data pollutant-induced changes at an unprecedented resolution scale laboratory field. In era rapid change, there urgent need advance our understanding real-world pollution behaviour. This therefore provides a roadmap major outstanding questions highlights cross-talk other disciplines order find answers.

Behavioural ecology at the spatial–social interface

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2023, Volume and Issue: 98(3), P. 868 - 886

Published: Jan. 23, 2023

ABSTRACT Spatial and social behaviour are fundamental aspects of an animal's biology, their spatial environments indelibly linked through mutual causes shared consequences. We define the ‘spatial–social interface’ as intersection individuals' phenotypes environments. Behavioural variation at spatial–social interface has implications for ecological evolutionary processes including pathogen transmission, population dynamics, evolution systems. link a foundation theory, vocabulary, methods. provide examples future directions integration introduce key concepts approaches that either implicitly or explicitly integrate processes, example, graph density‐dependent habitat selection, niche specialization. Finally, we discuss how movement ecology helps interface. Our review integrates behavioural identifies testable hypotheses

Residency and space use estimation methods based on passive acoustic telemetry data

Movement Ecology, Journal Year: 2023, Volume and Issue: 11(1)

Abstract Acoustic telemetry has helped overcome many of the challenges faced when studying movement ecology aquatic species, allowing to obtain unprecedented amounts data. This made it into one most widely used methods nowadays. Many ways analyse acoustic data have been available and deciding on how requires considering type research objectives, relevant properties (e.g., resolution, study design, equipment), habits researcher experience, among others. To ease this decision process, here we showcase (1) some estimate pseudo-positions positions from raw data, (2) residency (3) two-dimensional home occurrence range using geometric or hull-based density-distribution methods, a network-based approach, three-dimensional methods. We provide examples these were tested sample real With intend necessary background for selection method(s) that better fit specific objectives telemetry.

Human Footprint and Forest Disturbance Reduce Space Use of Brown Bears (Ursus arctos) Across Europe

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(1)

ABSTRACT Three‐quarters of the planet's land surface has been altered by humans, with consequences for animal ecology, movements and related ecosystem functioning. Species often occupy wide geographical ranges contrasting human disturbance environmental conditions, yet, limited data availability across species' constrained our understanding how pressure resource jointly shape intraspecific variation space use. Leveraging a unique dataset 758 annual GPS movement trajectories from 375 brown bears ( Ursus arctos ) range in Europe, we investigated effects (i.e., footprint index), predictability, forest cover disturbance, area‐based conservation measures on bear We quantified use at different spatiotemporal scales during growing season (May–September): home size; representing general requirements, 10‐day long‐distance displacement distances, routine 1‐day distances. found large all scales, which was profoundly affected index, vegetation productivity, recent disturbances creating opportunity pulses.

Integrating physiology into movement ecology of large terrestrial mammals

Journal of Experimental Biology, Journal Year: 2025, Volume and Issue: 228(Suppl_1)

Published: Feb. 15, 2025

ABSTRACT Movement paths are influenced by external factors and depend on an individual's navigation capacity (Where to move?), motion (How move?) ultimately driven internal physiological state (Why move?). Despite physiology underlying most aspects of this movement ecology framework, the physiology–movement nexus remains understudied in large terrestrial mammals. Within Commentary, we highlight processes that underpin framework how integrating measurements can provide mechanistic insights may enhance our understanding drivers animal movement. We focus mammals, which well represented within literature but under-represented studies integrate state. Recent advances biologging technology allow for variables, such as heart rate body movements, be recorded remotely continuously free-living animals. Biologging temperature additional into states driving Body not only provides a measure thermal stress, also index wellbeing through quantification nutrition, hydration, reproductive disease drive movements.

Abstract Movement of fishes in the aquatic realm is fundamental to their ecology and survival. can be driven by a variety biological, physiological environmental factors occurring across all spatial temporal scales. The intrinsic capacity movement impact fish individually ( e.g. , foraging) with potential knock‐on effects throughout ecosystem food web dynamics) has garnered considerable interest field ecology. advancement technology recent decades, combination ever‐growing threats freshwater marine systems, further spurred empirical research theoretical considerations. Given rapid expansion within its significant role informing management conservation efforts, contemporary multidisciplinary review about various components influencing outstanding.
