Measuring intrinsic rebound potential in exploited fish populations – example for sharks

Published online on 22. January 2015 New abbreviated calculation for measuring intrinsic rebound potential in exploited fish populations–example for sharks David W. Au, Susan E. Smith, Christina Show ABSTRACT: Intrinsic rebound potential, the demographic measure of a fish population’s productivity that sustains a given mortality, relates to a species’ resiliency, and can be useful for

Vertical Movement Patterns and Ontogenetic Niche Expansion in the Tiger Shark

Published on 28. January 2015 Vertical Movement Patterns and Ontogenetic Niche Expansion in the Tiger Shark, Galeocerdo cuvier André S. Afonso, Fábio H. V. Hazin ABSTRACT: Sharks are top predators in many marine ecosystems and can impact community dynamics, yet many shark populations are undergoing severe declines primarily due to overfishing. Obtaining species-specific knowledge on

Physiological and molecular responses of the spiny dogfish shark to high environmental ammonia

Published on 15. January 2015 Physiological and molecular responses of the spiny dogfish shark (Squalus acanthias) to high environmental ammonia: scavenging for nitrogen C. Michele Nawata, Patrick J. Walsh, Chris M. Wood ABSTRACT: In teleosts, a branchial metabolon links ammonia excretion to Na+ uptake via Rh glycoproteins and other transporters. Ureotelic elasmobranchs are thought to

Sharks senses and shark repellents

Sharks senses and shark repellents

Published online on 15. January 2015 Sharks senses and shark repellents Nathan S. Hart, Shaun P. Collin ABSTRACT: Despite over 70 years of research on shark repellents, few practical and reliable solutions to prevent shark attacks on humans or reduce shark bycatch and depredation in commercial fisheries have been developed. In large part, this deficiency
