The effect of temperature on haemoglobin–oxygen binding affinity in regionally endothermic and ectothermic sharks Phillip R. Morrison, Diego Bernal, Chugey A. Sepulveda, Colin J. Brauner ABSTRACT: Haemoglobin (Hb)–O2 binding affinity typically decreases with increasing temperature, but several species of ectothermic and regionally endothermic fishes exhibit reduced Hb thermal sensitivity. Regionally endothermic sharks, including the common
Recreational fishery discard practices influence use of tidal estuary by a large marine mesopredator Joni Pini-Fitzsimmons, Nathan A. Knott, Culum Brown ABSTRACT: Context: It is common for recreational anglers to discard waste produced from filleting catches back into the water, which results in a highly spatio-temporally predictable food subsidy for wildlife to scavenge. However, the

First record of the cirripede Anelasma squalicola Darwin, 1852 (Pollicipedidae) in the Mediterranean Sea ALBA MARTÍN-LÁZARO, WOLF ISBERT, AIGÜES REPULLÉS-ALBEDA, CRISTINA GARCÍA-RUIZ, FRANCISCO E. MONTERO ABSTRACT: Anelasma squalicola Darwin 1852, is a barnacle that occurs on elasmobranchs from the Atlantic, Pacific, Arctic and Indian Ocean. It infects sharks of the families Etmopteridae and Pentanchidae. The
Conservation successes and challenges for wide-ranging sharks and rays Nathan Pacoureau, John K. Carlson, Holly K. Kindsvater, Nicholas K. Dulvy ABSTRACT: Overfishing is the most significant threat facing sharks and rays. Given the growth in consumption of seafood, combined with the compounding effects of habitat loss, climate change, and pollution, there is a need to
Almost nothing is known about the tiger shark in South Atlantic waters Samuel Balanin, Rachel Ann Hauser-Davis, Eloísa Giareta, Patricia Charvet, Natascha Wosnick ABSTRACT: The tiger shark (Galeocerdo cuvier) has been relatively well assessed concerning biology and ecology aspects in both Atlantic and Pacific North America and in Caribbean waters. The amount of data in
Inferring habitat use of the Pacific White Shark using vertebral chemistry John A. Mohan, Alfonsina E. Romo-Curiel, Sharon Z. Herzka, R. J. David Wells, Nathan R. Miller, Oscar Sosa-Nishizaki, Emiliano García-Rodríguez ABSTRACT: The conservation and management of highly migratory sharks relies on understanding age-related movements and nursery habitat utilization. We reconstructed the habitat use and
Are shark teeth proxies for functional traits? A framework to infer ecology from the fossil record Jack A. Cooper, John N. Griffin, René Kindlimann, Catalina Pimiento ABSTRACT: Modern sharks have an evolutionary history of at least 250 million years and are known to play key roles in marine systems, from controlling prey populations to connecting

Guertin, Annie Page-Karjian, Brian A. Stacy, Dayv Lowry ABSTRACT: Sharks are the primary predator of large immature and mature sea turtles, yet the shark species responsible for
Multifaceted effects of bycatch mitigation measures on target/non-target species for pelagic longline fisheries and consideration for bycatch management Daisuke Ochi, Kei Okamoto, Shintaro Ueno ABSTRACT: The pelagic longline fishery, in an effort to reduce bycatch of sea turtles, have developed and deployed fisheries bycatch mitigation techniques such as replacing J/tuna hooks and squid bait with
Umbrella terms conceal the sale of threatened shark species: A DNA barcoding approach Ashleigh E. Sharrad, Patrick Reis-Santos, Jeremy Austin, Bronwyn M. Gillanders ABSTRACT: Food fraud in the seafood industry is a growing concern, including the authenticity and provenance of seafood products that are often unable to be confidently verified along complex, and at times
Global hotspots of shark interactions with industrial longline fisheries Echelle S. Burns, Darcy Bradley, Lennon R. Thomas ABSTRACT: Sharks are susceptible to industrial longline fishing due to their slow life histories and association with targeted tuna stocks. Identifying fished areas with high shark interaction risk is vital to protect threatened species. We harmonize shark catch
