On the Presence of White Shark, Carcharodon carcharias, in Uruguay

El Tiburón blanco (Carcharodon carcharias) (Lamniformes: Lamnidae) en el Uruguay C. Prigioni, A. Sappa, F. Leon, P. Nuñez ABSTRACT: A jaw of Carcharodon carcharias is reported, obtained in the 40s by fishermen from Valizas, Rocha. Bibliographic, oral and photographic references of their presence in Uruguayan waters are gathered and the causes of their apparent occasional

DNA analysis of elasmobranch products originating from Bangladesh reveals unregulated elasmobranch fishery

DNA analysis of elasmobranch products originating from Bangladesh reveals unregulated elasmobranch fishery

DNA analysis of elasmobranch products originating from Bangladesh reveals unregulated elasmobranch fishery and trade on species of global conservation concern Alifa Bintha Haque, Sudipta Arka Das, Aparna Riti Biswas ABSTRACT: Trade involving elasmobranch products in Bangladesh is a four-decade-long practice in large scale and there is little understanding of its impact on species composition, population,

Climate cooling and clade competition likely drove the decline of lamniform sharks

Climate cooling and clade competition likely drove the decline of lamniform sharks

Climate cooling and clade competition likely drove the decline of lamniform sharks Fabien L. Condamine, Jules Romieu, Guillaume Guinot ABSTRACT: Understanding heterogeneity in species richness between closely related clades is a key research question in ecology and evolutionary biology. Multiple hypotheses have been proposed to interpret such diversity contrasts across the tree of life, with

The neglected complexities of shark fisheries

The neglected complexities of shark fisheries

The neglected complexities of shark fisheries, and priorities for holistic risk-based management Hollie Booth, Dale Squires, E.J. Milner-Gulland ABSTRACT: Sharks and their cartilaginous relatives (Class Chondrichthyes, herein ‘sharks’) are one of the world’s most threatened species groups. Their slow life history traits and vulnerability to capture make them particularly susceptible to overfishing, and they are

Threatened shark species in pet food and beauty care products

Genetic identification of threatened shark species in pet food and beauty care products Diego Cardeñosa ABSTRACT: Contemporary global demand for shark commodities such as fins, meat, and liver oil, is arguably the main driver of shark overexploitation trends observed in the last three decades. Shark are most commonly traded for their fins to be used in

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

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

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
