Summary Upcoming reform of the E uropean U nion ( EU ) C ommon F isheries P olicy will be biggest change in fisheries management for a generation. A central plank this is proposed ban on discards, to aid creation economically and environmentally sustainable fisheries. This, together with global trend declining may have unforeseen knock‐on consequences large number scavenging seabirds that consume plentiful subsidy. Discards shaped many aspects seabird foraging, distribution population...
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...
Underwater noise from human activities appears to be rising, with ramifications for acoustically sensitive marine organisms and the functioning of ecosystems. Policymakers are beginning address risk ecological impact, but constrained by a lack data on current historic levels. Here, we present first nationally coordinated effort quantify underwater levels, in support UK policy objectives under EU Marine Strategy Framework Directive (MSFD). Field measurements were made during 2013-2014 at...
Microsatellites are widely used for many genetic studies. In contrast to single nucleotide polymorphism (SNP) and genotyping-by-sequencing methods, they readily typed in samples of low DNA quality/concentration (e.g. museum/non-invasive samples), enable the quick, cheap identification species, hybrids, clones ploidy. also have highest cross-species utility all types markers genotyping, but, despite this, when isolated from a only relatively small proportion will be utility. Marker...
Abstract Dramatic local population decline brought about by anthropogenic‐driven change is an increasingly common threat to biodiversity. Seabird life history traits make them particularly vulnerable such change; therefore, understanding connectivity and dispersal dynamics vital for successful management. Our study used a 357‐base pair mitochondrial control region locus sequenced 103 individuals 18 nuclear microsatellite loci genotyped 245 investigate structure in the Atlantic Pacific...
Abstract Aim Demographic linkage between subpopulations plays a critical role in population processes. Metapopulation dynamics, however, remains one of the most poorly understood aspects biology. This is especially true for small, pelagic seabirds because their discrete are located on offshore islands, separated by vast areas open ocean, making monitoring logistically challenging. Seabird populations often contain large numbers immature pre‐breeders that may be important subpopulation...
Oceanic fronts are key habitats for a diverse range of marine predators, yet how they influence fine-scale foraging behaviour is poorly understood. Here, we investigated the dive northern gannets Morus bassanus in relation to shelf-sea fronts. We GPS (global positioning system) tracked 53 breeding birds and examined relationship between 1901 dives (from time-depth recorders) thermal (identified via Earth Observation composite front mapping) Celtic Sea, Northeast Atlantic. (i) used...
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. We...
Seabirds are declining globally, though the threats they face differ among and within species populations. Following substantial population declines at several breeding colonies, Leach's Storm-Petrel (<em>Hydrobates leucorhous</em>) was uplisted from Least Concern to Vulnerable by International Union for Conservation of Nature (IUCN) in 2016. Reasons these unclear, it is important identify faces across its global range guide research directions inform conservation efforts. We solicited...
Detecting the effects of introduced artificial structures on marine environment relies upon research and monitoring programs that can provide baseline data necessary statistical power to detect biological and/or ecological change over relevant spatial temporal scales. Here we report on, assess use of, Baited Remote Underwater Video (BRUV) systems as a technique monitor diversity, abundance assemblage composition evaluate renewable energy infrastructure mobile epi-benthic species. The results...
Abstract Aim Ecosystem Approach to Fisheries Management has highlighted the importance of studying ecosystem functions and services, biological traits that drive them. Yet, services associated benefits they provide are rarely motive for creating marine protected area (MPA). Therefore, many MPA monitoring projects do not explicitly study these or underlying linked Location Lyme Bay MPA, located in SW England, was established 2008 protect reef biodiversity across a 206‐km 2 area, which...
Preserved and archived organic material offers huge potential for the conduct of retrospective long‐term historical ecosystem reconstructions using stable isotope analyses, but because isotopic exchange with preservatives obtained values require validation. The Continuous Plankton Recorder (CPR) Survey is most extensive monitoring program plankton communities worldwide has utilised ships opportunity to collect samples since 1931. To keep intact subsequent analysis, they are collected...
Coastal fisheries provide livelihoods and sustenance for millions of people globally but are often poorly documented. Data scarcity, particularly relating to spatio-temporal trends in catch effort, compounds wider issues governance capacity. This can hinder the implementation effectiveness spatial tools management or conservation. issue is acute developing low-income regions with many small-scale inshore high marine biodiversity, such as Southeast Asia. As a result, fleets operate...
Abstract Introduced mammals have devastated island nesting seabird populations worldwide. Declines in breeding seabirds on St Kilda, UK, been linked to climate change and predation from great skuas Stercorarius , but the introduced Kilda field mouse Apodemus sylvaticus hirtensis may also play a role by feeding adults, chicks or eggs. Here, we use stable isotopes blood potential dietary items investigate their foraging ecology, specifically focussing importance of marine foods diet. Mice were...
The extent of seabed licensed for offshore renewables is being expanded with the global requirement to reduce carbon emissions. opportunity Nature-based Solutions restoration, conservation, mariculture, infrastructure protection, and sequestration initiatives are explored internationally. Co-location marine renewable or structures conservation offers support populations threatened species contribute wider ecosystem services benefits. Building on experience from a North Sea project, we...
The giant freshwater whipray Urogymnus polylepis is a threatened species that vulnerable to riverine and coastal marine pressures. Despite its status, the range of U. still being determined. In this study, photographic evidence in Myanmar was provided through market surveys (2017-2018) social media (Sharks Rays Rakhine Facebook page, 2021). exposed fisheries habitat degradation pressures Myanmar; therefore, conservation management likely needed ensure populations persist into future.
