Fine-scale movement strategies of a non-obligate ram ventilator
Active acoustic telemetry tracking and tri-axial accelerometers reveal fine-scale movement strategies of a non-obligate ram ventilator Meese E.N., Lowe C.G. ABSTRACT: Background California horn sharks (Heterodontus francisci) are nocturnally active, non-obligate ram ventilating sharks in rocky reef habitats that play an important ecological role in regulating invertebrate communities. We predicted horn sharks would use an
Shark-catch composition and seasonality in the data-poor small-scale fisheries of the southern Gulf of Mexico
Shark-catch composition and seasonality in the data-poor small-scale fisheries of the southern Gulf of Mexico Juan Carlos Pérez-Jiménez, Armando Wakida-Kusunoki, Chrystian Hernández-Lazo, Manuel Mendoza-Carranza ABSTRACT: Regional ecological information is relevant to the international management of vulnerable species such as sharks. On the basis of monthly fishery data (2007–2010) from two small-scale multispecies fleets, namely, the
Shark and ray community structure in a turbid, nearshore coral reef habitat
Shark and ray community structure in a turbid, nearshore coral reef habitat Arthur Yon, Mark G. Meekan, Samantha Andrzejaczek, Sarah Martinez, Conrad W. Speed ABSTRACT: The coastline of northern Australia may be a refuge for elasmobranchs threatened or extirpated from much of their former ranges across South-East Asia. In this study, we used baited remote
First observations of white sharks attacking a live humpback whale
First observations of white sharks (Carcharodon carcharias) attacking a live humpback whale (Megaptera novaeangliae) Sasha Dines, Enrico Gennari ABSTRACT: To date, white shark (Carcharodon carcharias) feeding events involving large whales have largely been described only in terms of observed scavenging events. Scavenging occurs in all ecosystems and is usually associated with stochastic feeding events. In
