Investigating body condition and foraging success in young reef sharks between an atoll and an island system
Same species, different prerequisites: investigating body condition and foraging success in young reef sharks between an atoll and an island system Ornella C. Weideli, Ian A. Bouyoucos, Yannis P. Papastamatiou, Gauthier Mescam, Jodie L. Rummer, Serge Planes ABSTRACT: Acquiring and storing energy is vital to sharks of all age-classes. Viviparous shark embryos receive endogenous maternal
An environmental DNA tool for monitoring the status of Smalltooth Sawfish

Scharer, Katherine E. Schweiss, Jill M. Hendon, Nicole M. Phillips ABSTRACT: The Critically Endangered Smalltooth Sawfish, Pristis pectinata, was once widespread in the tropical and subtropical waters
High-performance suction feeding in an early elasmobranch
High-performance suction feeding in an early elasmobranch Michael I. Coates, Kristen Tietjen, Aaron M. Olsen, John A. Finarelli ABSTRACT: High-performance suction feeding is often presented as a classic innovation of ray-finned fishes, likely contributing to their remarkable evolutionary success, whereas sharks, with seemingly less sophisticated jaws, are generally portrayed as morphologically conservative throughout their history.

In situ observations of deep-living skates
In situ observations of deep-living skates in the eastern North Pacific L.A. Kuhnz, J.J. Bizzarro, D.A .Ebert ABSTRACT: We report on 18 years of in situ observations of seven skate species (2192 individual observations) in the eastern North Pacific (Vancouver Island, Canada to the Gulf of California, Mexico) between 200 and 3322 m depth. Biological (species,

Life-history traits inform population trends when assessing the conservation status of a declining tiger shark population
Life-history traits inform population trends when assessing the conservation status of a declining tiger shark population Christopher Brown, George Roff ABSTRACT: The assessment of the conservation status of wide ranging species depends on estimates of the magnitude of their population trends. The accuracy of trend estimates will depend on where and how many locations within
Shark-based tourism presents opportunities for facultative dietary shift in coral reef fish
Shark-based tourism presents opportunities for facultative dietary shift in coral reef fish Joshua A. Drew, Mallory McKeon ABSTRACT: Tourism represents an important opportunity to provide sustainable funding for many ecosystems, including marine systems. Tourism that is reliant on aggregating predator species in a specific area using food provisioning raises questions about the long-term ecological impacts

Social preferences and network structure in a population of reef manta rays
Social preferences and network structure in a population of reef manta rays Robert J. Y. Perryman, Stephanie K. Venables, Ricardo F. Tapilatu, Andrea D. Marshall, Culum Brown, Daniel W. Franks ABSTRACT: Understanding how individual behavior shapes the structure and ecology of populations is key to species conservation and management. Like many elasmobranchs, manta rays are
