Animal telemetry is a powerful tool for observing marine animals and the physical environments that they inhabit, from coastal continental shelf ecosystems to polar seas open oceans. Satellite-linked biologgers networks of acoustic receivers allow be reliably monitored over scales tens meters thousands kilometres, giving insight into their habitat use, home range size, phenology migratory patterns biotic abiotic factors drive distributions. Furthermore, environmental variables can collected using as autonomous sampling platforms, increasing spatial temporal coverage global oceanographic observation systems.

Abstract Aim Raptors serve critical ecological functions, are particularly extinction‐prone and often used as environmental indicators flagship species. Yet, there is no global framework to prioritize research conservation actions on them. We identify for the first time factors driving extinction risk scientific attention raptors develop a novel priority index (RCPI) priorities. Location Global.

Integrating physiology into movement ecology of large terrestrial mammals

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

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.

Evaluating Contributions of Recent Tracking-Based Animal Movement Ecology to Conservation Management

Frontiers in Ecology and Evolution, Journal Year: 2020, Volume and Issue: 7

The use of animal-born sensors for location-based tracking and bio-logging in terrestrial systems has expanded dramatically the past 10 years. This rapid expansion generated new data on how animals interact with respond to variation their environment, resulting important ecological, physiological evolutionary insights. However, although understanding finer details animal locations state also management relevance, applied studies are not prominent movement ecology literature. is despite long history urgent growing need evidence-based conservation guidance, especially challenging field human-wildlife interactions. goal this review evaluate realized contribution tracking-based solving specific problems identify barriers that may hinder contribution.

Message in a bottle: Open source technology to track the movement of plastic pollution

PLoS ONE, Journal Year: 2020, Volume and Issue: 15(12), P. e0242459 - e0242459

Rivers worldwide are now acting as major transport pathways for plastic pollution and discharge large quantities of waste into the ocean. Previous oceanographic modelling current drifter data have been used to predict movement accumulation in marine environment, but our understanding fate through riparian systems is still largely unknown.

Filling knowledge gaps in a threatened shorebird flyway through satellite tracking

Journal of Applied Ecology, Journal Year: 2019, Volume and Issue: 56(10), P. 2305 - 2315

Abstract Satellite‐based technologies that track individual animal movements enable the mapping of their spatial and temporal patterns occurrence. This is particularly useful in poorly studied or remote regions where there a need for rapid gathering relevant ecological knowledge to inform management actions. One such region East Asia, many intertidal habitats are being degraded at unprecedented rates shorebird populations relying on these show declines.

Spatial and Temporal Variability in Migration of a Soaring Raptor Across Three Continents

Frontiers in Ecology and Evolution, Journal Year: 2019, Volume and Issue: 7

Published: Sept. 10, 2019

Disentangling individual- and population-level variation in migratory movements is necessary for understanding migration at the species level. However, very few studies have analyzed these patterns across large portions of species' distributions. We compiled a telemetry dataset on globally endangered Egyptian Vulture Neophron percnopterus (94 individuals, 188 completed journeys), tracked ~70% global range, to analyze spatial temporal variability within among individuals populations. found high connectivity scales (i.e. different subpopulations showed little overlap wintering areas), but diffuse subpopulations, with ranges up 4000 km apart birds breeding same region each subpopulation visiting 28 countries (44 total). Additionally, Vultures exhibited level flexibility individual basic parameters. Subpopulations differed significantly travel distance straightness movements, while differences speed duration as much between seasons subpopulations. The total distances migrations by from Balkans Caucasus were twice long less direct than those Western Europe, consequently longer duration, despite faster speeds. These appear be largely attributable more numerous wider geographic barriers (water bodies) along eastern flyway. also that adult spring Europe slower fall migrations. encourage further research assess underlying mechanisms extent which environmental change could affect movement ecology population trends.

Extreme mobility of the world’s largest flying mammals creates key challenges for management and conservation

BMC Biology, Journal Year: 2020, Volume and Issue: 18(1)

Published: Aug. 20, 2020

Abstract Background Effective conservation management of highly mobile species depends upon detailed knowledge movements individuals across their range; yet, data are rarely available at appropriate spatiotemporal scales. Flying-foxes ( Pteropus spp.) large bats that forage by night on floral resources and rest day in arboreal roosts may contain colonies many thousands individuals. They the largest mammals capable powered flight, mobile, which makes them key seed pollen dispersers forest ecosystems. However, mobility also facilitates transmission zoonotic diseases brings conflict with humans, so they require a precarious balancing concerns throughout Old World range. Here, we analyze Australia-wide 201 satellite-tracked individuals, providing unprecedented detail inter-roost three flying-fox species: alecto , P . poliocephalus scapulatus jurisdictions over up to 5 years. Results Individuals were estimated travel long distances annually among network 755 1427–1887 km; 2268–2564 3782–6073 km), but little uniformity directions travel. This indicates populations composed extremely move nomadically species-specific rates. all exhibited very low fidelity locally, resulting high daily colony turnover rates 11.9 ± 1.3%; 17.5 36.4 6.5%). form nodes vast continental dynamic “staging posts” through far wide ranges. Conclusions The extreme reported here demonstrates extent ecological linkages nomadic flying-foxes provide Australia’s contemporary fragmented landscape, profound implications for ecosystem services dynamics populations. In addition, means impacts from local actions can readily reverberate ranges; therefore, need be assessed reference elsewhere hence national coordination. These findings underscore sound understanding animal movement support evidence-based, transboundary policy, tailored unique ecologies species.
