Marine mammals can play important ecological roles in aquatic ecosystems, and their presence be key to community structure function. Consequently, marine are often considered indicators of ecosystem health flagship species. Yet, historical population declines caused by exploitation, additional current threats, such as climate change, fisheries bycatch, pollution maritime development, continue impact many mammal species, at least 25% classified threatened (Critically Endangered, Endangered or...
Young animals must learn to forage effectively survive the transition from parental provisioning independent feeding. Rapid development of successful foraging strategies is particularly important for capital breeders that do not receive guidance after weaning. The intrinsic and extrinsic drivers variation in ontogeny are poorly understood many species. Grey seals (Halichoerus grypus) typical breeders; pups abandoned on natal site a brief suckling phase, develop skills without external input....
Offshore man-made structures (MMS) such as oil and gas (O&G) platforms, pipelines wind energy developments are present in shelf seas worldwide can potentially influence ecosystem dynamics services. The number, type age of these is changing the sector expands whilst O&G reach end economic viability decommissioned. North Sea an area which supports major offshore production consequently has a particularly high density MMS which, according to OSPAR 98/3 decision, will need be removed after...
Capsule Three quarters of tracked Northern Gannets (Morus bassanus) at Grassholm gathered in rafts around the colony, concentrated within a recently designated at-sea Special Protection Area (SPA), but rafting was not correlated with foraging effort.Aims To investigate incidence, distribution and implications Gannet behaviour waters adjacent to large colony.Methods Using bird-borne global positioning system (GPS) loggers we reconstructed movement used speed filter identify 10 km colony.

Rapid development of a successful foraging strategy is critical for juvenile survival, especially naïve animals that receive no parental guidance. However, this process poorly understood many species. Although observation early‐life movements increasingly possible with miniaturisation animal‐borne telemetry devices, analytical limitations remain. Here, we tracked 29 recently‐weaned grey seal Halichoerus grypus pups from colonies in two geographically distinct regions the United Kingdom. We...
Abstract For the Western Indian Ocean region, there is a significant knowledge gap regarding marine turtle nesting on continental coast of East Africa. Here we present results from long-term (2000–2020) community-based monitoring programme in and around Watamu Marine National Park, Kenya, covering 30 km coastline (c. 6% national total). Conservation actions effectively protected turtles resulted near-total cessation illegal egg harvesting Park. Collected data indicate this an important index...
Background: Foraging rates directly influence animals' energetic intake and expenditure are thus linked to body condition the ability survive reproduce. Further, understanding underlying processes driving a species' behaviour habitat use is important as changes in could result from environmental conditions. Methods: In this study, dives of Saimaa ringed seals (Pusa hispida saimensis) were classified for first time using hidden Markov models telemetry data collected on individual dives,...

Understanding how marine predators find patchily distributed prey resources in a dynamic environment is key to identifying important ecological areas for ecosystem-level conservation management. However, the mechanisms underpinning foraging often result from complex interactions between static and covariates (e.g. topography currents). Modelling habitat associations with hydrodynamic processes rarely useful when attempting identify characterise across an individual’s range. Investigating...
Marine predator populations are crucial to the structure and functioning of ecosystems. Like many taxa, pinnipeds face an increasingly complex array natural anthropogenic threats. Understanding relationship between at-sea processes trends in abundance at land-based monitoring sites requires robust estimates distribution, often on multi-region scales. Such understanding is critical for effective conservation management, but limited spatial extent by coverage animal-borne tracking data. Grey (...
The wind climate in Hong Kong is generally mild, but occasionally the region hit by very strong winds form of typhoons developing South China Sea. uncertainty associated with strength, direction and landfall these has led to development a design code dictating high speeds that Stonecutters Bridge must be able withstand; frequent low speed situations also have implications for aerodynamics thus daily service bridge.

There is high spatial overlap between grey seals and shipping traffic, the functional hearing range of indicates sensitivity to underwater noise emitted by ships. However, there still very little data regarding exposure noise, constraining effective policy decisions. Particularly, are few predictions that consider at-sea movement seals. Consequently, this study aimed predict adult pups along a three-dimensional track, assess influence characteristics on sound levels. Using ship location...
