Development and regeneration of the crushing dentition in skates (Rajidae) Liam J. Rasch, Rory L. Cooper, Charlie Underwood, Wesley A. Dillard, Alexandre P. Thiery, Gareth J. Fraser ABSTRACT: Sharks and rays (elasmobranchs) have the remarkable capacity to continuously regenerate their teeth. The polyphyodont system is considered the ancestral condition of the gnathostome dentition. Despite this
Human‐induced shifts in habitat use and behaviour of a marine predator: the effects of bait provisioning in the blacktip reef shark J. Mourier, J. Claudet, S. Planes ABSTRACT: While the negative effects of consumptive pressures on marine predators are well established, the effects of increasing non‐consumptive activities such as wildlife tourism are still understudied. As
From plentiful to critically endangered: Demographic evidence of the artisanal fisheries impact on the smalltail shark (Carcharhinus porosus) from Northern Brazil Francisco Marcante Santana, Leonardo Manir Feitosa, Rosângela Paula Lessa ABSTRACT: The smalltail shark, Carcharhinus porosus, was the most abundant elasmobranch species in fisheries off Brazil’s northern coast (BNC) in the 1980s, but its population

A review of potential taxonomic barriers to the effective management of Gulf elasmobranch fisheries Aaron C. Henderson ABSTRACT: Species-specific biological data are commonly combined with fishery operational data to model exploited stocks and determine appropriate levels of exploitation. However, this approach to fishery management is predicated using the ability of fishery data collectors to correctly

Estimating marine protected area network benefits for reef sharks Gerardo Martín, Mario Espinoza, Michelle Heupel, Colin A. Simpfendorfer ABSTRACT: Animal movement has direct applications in spatial management and conservation planning, yet it is rarely taken into account for the design of natural protected areas. For instance, reef shark species are thought to benefit from marine
