A global survey of coral reefs reveals that overfishing is driving resident shark species toward extinction, causing diversity deficits in reef elasmobranch (shark and ray) assemblages. Our species-level analysis revealed declines 60 to 73% for five common individual were not detected at 34 47% surveyed reefs. As become more shark-depleted, rays begin dominate Shark-dominated assemblages persist wealthy nations with strong governance highly protected areas, whereas poverty, weak governance,...
Sharks are a globally threatened group of marine fishes that often breed in their natal region origin. There has even been speculation female sharks return to exact birthplace ('natal philopatry'), which would have important conservation implications. Genetic profiling lemon (Negaprion brevirostris) from 20 consecutive cohorts (1993-2012) at Bimini, Bahamas, showed certain females faithfully gave birth this site for nearly two decades. At least six born the 1993-1997 returned give 14-17...
Electronic tags are significantly improving our understanding of aquatic animal behavior and emerging as key sources information for conservation management practices. Future integrative biology ecology studies will increasingly rely on data from electronic tagging. Continued advances in tracking hardware software needed to provide the knowledge required by managers policymakers address challenges posed world's changing ecosystems. We foresee multiplatform systems simultaneously monitoring...
Summary The field of acoustic telemetry has evolved rapidly and now permits the remote sensing animal behaviour, movement, physiology survival in environments, species not previously possible. However, an inability to detect when a telemetered is consumed by predator can complicate accurate interpretation data. In this paper, we describe efforts taken test two generations novel prototype transmitter designed specifically predation. Testing involved either staged predation events where tagged...
A thorough understanding of movement patterns a species is critical for designing effective conservation and management initiatives. However, generating such information large marine vertebrates challenging, as they typically move over long distances, live in concealing environments, are logistically difficult to capture and, upper-trophic predators, naturally low abundance. As bodied, broadly distributed tropical shark restricted coastal shelf habitats, the great hammerhead Sphyrna mokarran...
Biotelemetry data have been successfully incorporated into aspects of fishery and fish habitat management; however, the processes knowledge mobilization are rarely published in peer-reviewed literature but valuable interest to conservation scientists. Here, we explore case examples from Ocean Tracking Network (OTN), including Pacific salmon (Oncorhynchus spp.) British Columbia, Canada; Greenland halibut (Reinhardtius hippoglossoides) Cumberland Sound, lemon sharks (Negaprion brevirostris)...
Abstract Population structure, distribution, abundance and dispersal arguably underpin the entire field of animal ecology, with consequences for regional species persistence, provision ecosystem services. Divergent migration behaviours among individuals or populations are an important aspect ecology highly mobile animals, allowing to exploit spatially temporally distributed food space resources. This study investigated spatial lake sturgeon ( A cipenser fulvescens ) within barrier free...
Management boundaries that define populations or stocks of fish form the basis fisheries planning. In Arctic, decreasing sea ice extent is driving increasing development, highlighting need for ecological data to inform management. Cumberland Sound, southwest Baffin Island, an indigenous community fishery was established in 1987 targeting Greenland halibut (Reinhardtius hippoglossoides) through ice. Following its Sound Boundary (CSMB) designated and a total allowable catch (TAC) assigned...
We used an array of fixed acoustic receivers (N = 42) to track the summer marine movements 121 anadromous Arctic char (Salvelinus alpinus) equipped with transmitters at three locations in Cambridge Bay region, where commercial and subsistence fisheries target species. The timing transitions between salt fresh water was influenced by putative river origin tagged individuals, but not their size or sex. Females, however, were more likely remain proximate rivers they throughout summer. A...
Tonic immobility is a widely used technique for the surgical implantation of acoustic tags in elasmobranchs (sharks, skates, and rays), yet it still not broadly recognised as an acceptable procedure by many regulatory bodies, animal care committees, even journal ethics standards. To highlight its regular use applicability field procedure, literature search was conducted on anaesthetic adopted all existing elasmobranch-focused telemetry papers, up to 31 December 2013. A total 57 studies were...
Abstract Aim Climate change is altering marine ecosystems worldwide and most pronounced in the Arctic. Economic development increasing leading to more disturbances pressures on Arctic wildlife. Identifying areas that support higher levels of predator abundance biodiversity important for implementation targeted conservation measures across Location Primarily Canadian waters but also parts United States, Greenland Russia. Methods We compiled largest data set existing telemetry predators North...
When employing acoustic telemetry to study aquatic species, understanding the functional dynamics of monitoring system is essential for effective design, data interpretation, and analysis. Typically, researchers are concerned with maximum detection range consequently tend employ largest most powerful tags species can carry without considerable energetic burden. In ideal conditions low ambient noise environments, attenuation, reflective structure, higher powered be detected at larger...
Abstract Anthropogenic noise associated with shipping has emerged as a major disruptor of aquatic animal behavior worldwide. The Arctic marine realm historically experienced little noise‐generating human activity; however, the continual loss sea ice facilitated dramatic increase in activity. Here, we use combination acoustic telemetry and modeling ship to examine temporospatial habitat key forage fish, cod ( Boreogadus saida ) presence absence vessels Resolute Bay, Nunavut, Canada. movement...
A large reef manta ray (Manta alfredi) aggregation has been observed off the north Sudanese Red Sea coast since 1950s. Sightings have predominantly within boundaries of a marine protected area (MPA), which was designated UNESCO World Heritage Site in July 2016. Contrasting economic development trajectories proposed for (small-scale ecotourism and large-scale island development). To examine space-use, Wildlife Computers® SPOT 5 tags were secured to three rays. two-state switching Bayesian...
Marine protected areas (MPAs) have emerged as potentially important conservation tools for the of biodiversity and mitigation climate impacts. Among MPAs, a large percentage has been created with implicit goal protecting shark populations, including 17 sanctuaries which fully protect sharks throughout their jurisdiction. The Commonwealth Bahamas represents long-term MPA sharks, following banning commercial longlining in 1993 subsequent designation sanctuary 2011. Little is known, however,...
