Clashing conservation values: The social complexities of shark depredation
Clashing conservation values: The social complexities of shark depredation Kristin Hoel, Andrew Chin, Jacqueline Laub ABSTRACT: Human-wildlife conflicts (HWC) are increasingly prominent worldwide, which can complicate conservation efforts for wildlife. Shark depredation, when a shark preys on a fishers’ catch, is a growing HWC in global fisheries and is particularly contentious in Queensland, Australia, causing

Microstructure of the Bonnethead Shark Olfactory Rosette
Microstructure of the Bonnethead Shark (Sphyrna tiburo) Olfactory Rosette Lauren E Simonitis, Christopher D Marshall ABSTRACT: The unusual shape of sphyrnids (hammerhead sharks) heads has led to many functional hypotheses of potential sensory advantages and enhanced olfactory performance. Recent investigations into the flow of water within the sphyrnid olfactory chamber demonstrate that this complex structure

Decoding the dynamics of dental distributions: insights from shark demography and dispersal
Decoding the dynamics of dental distributions: insights from shark demography and dispersal Sora L. Kim, Justin D. Yeakel, Meghan A. Balk, Jaelyn J. Eberle, Sarah Zeichner, Dina Fieman, Jürgen Kriwet ABSTRACT: Shark teeth are one of the most abundant vertebrate fossils, and because tooth size generally correlates with body size, their accumulations document the size

Sixth sense in the deep-sea: the electrosensory system in ghost shark Chimaera monstrosa Bottaro, M. ABSTRACT: Animals that continually live in deep sea habitats face unique challenges and require adaptive specializations solutions in order to locate and identify food, predators, and conspecifics. The Ampullae of Lorenzini are specialized electroreceptors used by chondrichthyans for important biological
