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.

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.

Movement predictability of individual barn owls facilitates estimation of home range size and survival

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

Published: Feb. 7, 2023

Abstract Background There is growing attention to individuality in movement, its causes and consequences. Similarly other well-established personality traits (e.g., boldness or sociability), conspecifics also differ repeatedly their spatial behaviors, forming behavioral types (“spatial-BTs”). These spatial-BTs are typically described as the difference mean-level among individuals, intra-individual variation (IIV, i.e., predictability) only rarely considered. Furthermore, factors determining predictability ecological consequences for broader space-use patterns largely unknown, part because was mostly tested captivity with repeated assays).

Cows that are less active in the chute have more optimal grazing distribution

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 2, 2025

Abstract Individual grazing patterns among cattle can contribute to sustainability of land use, however, little is known about the consistency these patterns. To address this knowledge gap, fifty Angus x Hereford cows were observed in repeated assays: A management assay (handling procedure, narrow chute, hydraulic squeeze), a social-feed trade-off (SFTA; choice between social mates and feed item), novel approach (choice item with pattern). The same tracked GPS collars over two seasons (June-August 2021 2022) average grazing-related metrics (e.g., elevation used, distance traveled) calculated within each season. Cows more passive response chute found at higher ( p = 0.017), further from water 0.043), closer supplement sites 0.029). that had latency SFTA traveled shorter distances on rangeland 0.035). Thus, there was some evidence isolation optimal (grazed underutilized areas range elevations sources). Selecting foraging based observable behaviors during handling could improve grazing.

Spur-winged lapwings show spatial behavioural types with different mobility and exploration between urban and rural individuals

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 292(2038)

Published: Jan. 1, 2025

Understanding how wildlife responds to the spread of human-dominated habitats is a major challenge in ecology. It still poorly understood urban areas affect space-use patterns and consistent intra-specific behavioural differences (i.e. types; BTs), which turn shape various ecological processes. To address these questions, we investigated movements common resident wader, spur-winged lapwing ( Vanellus spinosus ), hypothesizing that individuals will be more mobile than rural ones. We used an ATLAS tracking system track many n = 135) at high resolution over several months each. first established daily movement indices show among individuals, acting as spatial-BTs. Then focusing on two main principle components lapwings’ movements—mobility position along exploration–exploitation gradient—we BTs are shaped by urbanization, season (nesting versus non-nesting) sex. found lapwings were indeed both seasons. Furthermore, females less explorative females, especially during nesting season. These results highlight urbanization affects behaviour, even apparently urban-resilient avian residents. This underscores need consider possible consequences only apparent through advanced methods.

Variability in space use among conspecifics can emerge from foraging strategies that track available resources, especially riverscapes promote high synchrony between prey pulses and consumers. Projected changes riverscape hydrological regimes due to water management climate change accentuate the need understand natural variability animal its implications for population dynamics ecosystem function.

Personality, space use, and networks directly and indirectly explain tick infestation in a wild population of lizards

Ecological Monographs, Journal Year: 2025, Volume and Issue: 95(1)

Abstract Host personality can markedly affect parasite transmission. Especially for parasites with indirect transmission through the environment, effects of consistent among‐individual differences in behavior may have both direct and components. For example, mediate how hosts respond to infected individuals likelihood that indirectly interact conspecifics (e.g., by visiting patches previously contaminated). Integrating parasites, personality, these different kinds interaction networks constitutes a key step toward understanding natural systems. We evaluated elements using 5‐year field study wild population sleepy lizards, Tiliqua rugosa , their tick which transmit among lizards lizards' shared use refuges. Using Bayesian models, we (1) predictors lizard infestation probability intensity (i.e., average count when infested) (2) relationships predictors. used latter set models assess between metrics.

Linking behavioural variance to environmental heterogeneity: Variance decomposition in surface versus cave isopod populations

Abstract A longstanding question in evolutionary biology is how within‐population phenotypic variation maintained under natural selection. The fluctuating selection hypothesis suggests that genetic and scales with fluctuations over space time. This implies might be greater populations than stable environmental conditions. However, this aspect has rarely been investigated, likely because habitats minimal are rare. We addressed by comparing surface cave of the freshwater isopod Asellus aquaticus species complex.

Chemical pollution is one of the fastest-growing agents global change. Numerous pollutants are known to disrupt animal behavior, alter ecological interactions, and shift evolutionary trajectories. Crucially, both chemical individual organisms nonrandomly distributed throughout environment. Despite this fact, current evidence for chemical-induced impacts on wildlife largely stems from tests that restrict organism movement force homogeneous exposures. While such approaches have provided pivotal ecotoxicological insights, they overlook dynamic spatiotemporal interactions shape wildlife-pollution relationships in nature. Indeed, seemingly simple notion animals move environment creates a complex many which never been theoretically modeled or experimentally tested. Here, we conceptualize between variation highlight their implications. We propose three-pronged approach-integrating silico modeling, laboratory experiments allow movement, field-based tracking free-ranging animals-to bridge gap controlled studies real-world Advances telemetry, remote sensing, computational models provide necessary tools quantify these paving way new era ecotoxicology accounts complexity.
