Seafood is an essential source of protein for more than 3 billion people worldwide, yet bycatch threatened species in capture fisheries remains a major impediment to sustainability. Management measures designed reduce often result significant economic losses and even closures. Static spatial management approaches can also be rendered ineffective by environmental variability climate change, as productive habitats shift introduce new interactions between human activities protected species. We...
Significance Shark populations are declining worldwide because of overexploitation by fisheries with unknown consequences for ecosystems. Although the harvest oceanic sharks remains largely unregulated, knowing precisely where they interact fishing vessels will better aid their conservation. We satellite track six species shark and two entire longline vessel fleets across North Atlantic over multiple years. Sharks actively select aggregate in space-use “hotspots” characterized thermal fronts...
Summary Identifying priority areas for marine vertebrate conservation is complex because species of concern are highly mobile, inhabit dynamic habitats and difficult to monitor. Many vertebrates known associate with oceanographic fronts – physical interfaces at the transition between water masses foraging migration, making them important candidate sites conservation. Here, we review associations how they vary scale, regional oceanography ecology. Accessibility, spatiotemporal predictability...
The oceanographic drivers of marine vertebrate habitat use are poorly understood yet fundamental to our knowledge ecosystem functioning. Here, we composite front mapping and high-resolution GPS tracking determine the significance mesoscale fronts as physical foraging selection in northern gannets Morus bassanus. We tracked 66 breeding from a Celtic Sea colony over 2 years used residence time identify area-restricted search (ARS) behaviour. Composite maps identified thermal chlorophyll-a at...
Commercial capture fisheries produce huge quantities of offal, as well undersized and unwanted catch in the form discards. Declines global catches legislation to ban discarding will significantly reduce discards, but this subsidy supports a large scavenger community. Understanding potential impact declining discards for scavengers should feature an eco-system based approach management, requires greater knowledge scavenger/fishery interactions. Here we use bird-borne cameras, tandem with GPS...
Understanding and predicting the responses of wide‐ranging marine predators such as cetaceans, seabirds, sharks, turtles, pinnipeds large migratory fish to dynamic oceanographic conditions requires habitat‐based models that can sufficiently capture their environmental preferences. Marine ecosystems are inherently dynamic, animal–environment interactions known occur over multiple, nested spatial temporal scales. The resolution averaging data layers therefore key considerations in modelling...

Species distribution models (SDMs) have become key tools for describing and predicting species habitats. In the marine domain, environmental data used in modelling distributions are often remotely sensed, as such limited capacity interpreting vertical structure of water column, or sampled situ, offering minimal spatial temporal coverage. Advances ocean improved our to explore subsurface features, yet there has been integration features SDMs. Using output from a data-assimilative...
Seascape ecology, the marine-centric counterpart to landscape is rapidly emerging as an interdisciplinary and spatially explicit ecological science with relevance marine management, biodiversity conservation, restoration. While important progress in this field has been made past decade, there no coherent prioritisation of key research questions help set future agenda for seascape ecology. We used a 2-stage modified Delphi method solicit applied from academic experts ecology then asked...
Abstract Aim Ecological niche modelling can provide valuable insight into species' environmental preferences and aid the identification of key habitats for populations conservation concern. Here, we integrate biologging, satellite remote‐sensing ensemble ecological models ( EENM s) to identify predictable foraging a globally important population grey‐headed albatross GHA ) Thalassarche chrysostoma .

Incidental catch of nontarget species (bycatch) is a major barrier to ecological and economic sustainability in marine capture fisheries. Key mitigating bycatch an understanding the habitat requirements target influence heterogeneity variability dynamic environment. While patterns overlap among fisheries habitats taxonomically diverse range vertebrates have been reported, mechanistic real-time physical drivers events lacking. Moving from describing toward processes, we apply Lagrangian...
Summary Understanding the mechanisms that link oceanographic processes and marine vertebrate space use is critical to our knowledge of ecosystem functioning, for effective management populations conservation concern. The basking shark C etorhinus maximus has been observed in association with fronts – physical interfaces at transitions between water masses exploiting foraging opportunities resulting from zooplankton aggregation. However, scale, significance variability these associations have...
Abstract The ocean is a dynamic environment inhabited by diverse array of highly migratory species, many which are under direct exploitation in targeted fisheries. timescales variability the marine realm coupled with extreme mobility ocean‐wandering species such as tuna and billfish complicates fisheries management. Developing eco‐informatics solutions that allow for near real‐time prediction distributions mobile an important step towards maturation management ecological forecasting. Using...

Abstract Dynamic management ( DM ) is a novel approach to spatial that aligns scales of environmental variability, animal movement and human uses. While static approaches rely on one‐time assessments biological, environmental, economic, and/or social conditions, dynamic repeatedly assess conditions produce regularly updated recommendations. Owing this complexity, particularly regarding operational challenges, examples applied are rare. To implement , scientific methodologies operationalized...
How animal movement decisions interact with the distribution of resources to shape individual performance is a key question in ecology. However, links between spatial and behavioural ecology fitness consequences are poorly understood because outcomes resource selection decisions, such as energy intake, rarely measured. In open ocean, mesoscale features (approx. 10–100 km) fronts eddies can aggregate prey thereby drive foraging vertebrates through bottom-up biophysical coupling. These...
Vessel tracking and habitat modeling reveal hotspots of overlap between industrial fishing the pelagic fishes.
Advances in ocean observing technologies and modeling provide the capacity to revolutionize management of living marine resources. While traditional fisheries approaches like single-species stock assessments are still common, a global effort is underway adopt ecosystem-based (EBFM) approaches. These consider changes physical environment interactions between ecosystem elements, including human uses, holistically. For example, integrated aim synthesize suite observations (physical, biological,...
