The application of precaution in elasmobranch conservation and management in the Mediterranean Sea
The application of precaution in elasmobranch conservation and management in the Mediterranean Sea Lydia Koehler, Ioannis Giovos, Jason Lowther ABSTRACT: This study examined the integration and application of the precautionary principle at national level for the conservation and management of elasmobranchs. Three countries, Greece, Malta, and Cyprus were assessed. Based on national legislation, policies, and
Abundance dynamics of a new, endemic batoid from Brazil: The Lutz’s stingray
Abundance dynamics of a new, endemic batoid from Brazil: The Lutz’s stingray, Hypanus berthalutzae Ilka Branco-Nunes. Yuri Niella, Fábio Hissa Vieira Hazin, Emmanuelly Creio, Paulo Guilherme Vasconcelos de Oliveira, André Sucena Afonso ABSTRACT: The Lutz’s stingray, Hypanus berthalutzae, is a recently identified, endemic dasyatid species which occurs in shallow habitats exclusively along most of the
Testing the ‘mistaken identity theory’ behind shark bites on humans
A shark’s eye view: testing the ‘mistaken identity theory’ behind shark bites on humans Laura A. Ryan, David J. Slip, Lucille Chapuis, Shaun P. Collin, Enrico Gennari, Jan M. Hemmi, Martin J. How, Charlie Huveneers, Victor M. Peddemors, Louise Tosetto, Nathan S. Hart ABSTRACT: Shark bites on humans are rare but are sufficiently frequent to
Defining distribution and habitat use of west-central Florida’s coastal sharks through a research and education program
Defining distribution and habitat use of west-central Florida’s coastal sharks through a research and education program Lindsay L. Mullins, J. Marcus Drymon, Moriah Moore, Adam Skarke, Alan Moore, John C. Rodgers ABSTRACT: Identifying critical habitat for highly mobile species such as sharks is difficult, but essential for effective management and conservation. In regions where baseline
The use of fishers’ Local Ecological Knowledge to reconstruct fish behavioural traits and fishers’ perception of conservation relevance of elasmobranchs in the Mediterranean Sea
The use of fishers’ Local Ecological Knowledge to reconstruct fish behavioural traits and fishers’ perception of conservation relevance of elasmobranchs in the Mediterranean Sea BARBATO, M., BARRÍA, C., BELLODI, A., BONANOMI, S., BORME, D., ĆETKOVIĆ, I., COLLOCA, F., COLMENERO, A., CROCETTA, F., De CARLO, F., DEMİR, E., Di LORENZO, M., FOLLESA, M., GARIBALDI, F., GIGLIO,
Advances in the study of the trophic niche of batoids with distribution in Mexican waters
Advances in the study of the trophic niche of batoids with distribution in Mexican waters Francisco Serrano-Flores, Yassir E. Torres-Rojas, Matthew J. Ajemian, Manuel Mendoza-Carranza, Juan C. Pérez-Jiménez ABSTRACT: Batoid (rays and skates) populations are declining worldwide, with unknown ecological consequences due to lacking consolidated data on the trophic ecology of these species. Such trends
Contemporary records of the rare and critically endangered angular rough shark from the eastern Adriatic Sea
Contemporary records of the rare and critically endangered angular rough shark, Oxynotus centrina (Linnaeus, 1758), from the eastern Adriatic Sea Andrej A. Gajić, Suvad Lelo, Aleksandar Joksimović, Ana Pešić, Jovana Tomanić, Hajrudin Beširović, Branko Dragičević ABSTRACT: Angular rough shark, Oxynotus centrina (Linnaeus, 1758), is a poorly known and rare bathydemersal shark inhabiting continental shelves and
Behavioural thermoregulation linked to foraging in blue sharks
Behavioural thermoregulation linked to foraging in blue sharks Yuuki Y. Watanabe, Itsumi Nakamura, Wei-Chuan Chiang ABSTRACT: Large pelagic fishes often dive and surface repeatedly as if they were airbreathers, raising a question about the functions of these movements. Some species (e.g., bigeye tuna, ocean sunfish) apparently alternate foraging in deep cold waters and rewarming in
Novel Insights Into the Genetic Population Connectivity of Transient Whale Sharks in Pacific Panama
Novel Insights Into the Genetic Population Connectivity of Transient Whale Sharks (Rhincodon typus) in Pacific Panama Provide Crucial Data for Conservation Efforts Héctor M. Guzmán, Caitlin E. Beaver, Edgardo Díaz-Ferguson ABSTRACT: The whale shark (Rhincodon typus) is an endangered and highly migratory species, of which solitary individuals or aggregations are observed in oceans worldwide and
Global shifts in species richness have shaped carpet shark evolution
Global shifts in species richness have shaped carpet shark evolution Bret M Boyd, Jason C Seitz ABSTRACT: Background: The evolutionary processes that shape patterns of species richness in marine ecosystems are complex and may differ between organismal groups. There has been considerable interest in understanding the evolutionary processes that led to marine species richness being
Potential of electric fields to reduce bycatch of highly threatened sawfishes
Potential of electric fields to reduce bycatch of highly threatened sawfishes Kátya Abrantes, Adam Barnett, Maarten Soetaert, Peter M. Kyne, Adrianne Laird, Lyle Squire, Jamie Seymour, Barbara E. Wueringer, Jessica Sleeman, Charlie Huveneers ABSTRACT: Sawfishes are among the most threatened families of marine fishes and are susceptible to incidental capture in net fisheries. Since bycatch
Leveraging shark-fin consumer preferences to deliver sustainable fisheries
Leveraging shark-fin consumer preferences to deliver sustainable fisheries Xuehong Zhou, Hollie Booth, Mingzhe Li, Zhifan Song, Douglas C. MacMillan, Wei Zhang, Qiang Wang, Diogo Veríssimo ABSTRACT: At least one third of sharks and their cartilaginous relatives (Class Chondrichthyes) meet the IUCN Red List Criteria for being threatened with extinction. Overfishing is the primary threat, with
Investigating Attitudes Toward Sharks in Australia
Investigating Attitudes Toward Sharks in Australia Brianna Le Busque, Philip Roetman, Jillian Dorrian, Carla Litchfield ABSTRACT: Understanding attitudes toward sharks and the factors associated with them is important for promoting positive attitudes and support for conservation initiatives. We aimed to investigate attitudes toward two different shark species in an Australian context: white sharks (Carcharodon carcharias,
