Character based identification system for Elasmobranchs
Character based identification system for Elasmobranchs for conservation and forensic applications Sneha Vargheese, Labrechai Mog Chowdhury, Shijin Ameri, Anjela mercy A, Kathirvelpandian A ABSTRACT: The term Elasmobranchs or Chondrichthyans refer to the group of marine organisms include sharks, skates, rays and chimeras. Due to high demand most of the Elasmobranch species depleted drastically in recent

MAISEY ABSTRACT: A new species of kitefin shark (Squaliformes; Dalatiidae) is described from the Gulf of Mexico (Western North Atlantic
Deiminated proteins in extracellular vesicles and plasma of nurse shark
Deiminated proteins in extracellular vesicles and plasma of nurse shark (Ginglymostoma cirratum) – Novel insights into shark immunity Michael F. Criscitiello, Igor Kraev, Sigrun Lange ABSTRACT: Peptidylarginine deiminases (PADs) are phylogenetically conserved calcium-dependent enzymes which post-translationally convert arginine into citrulline in target proteins in an irreversible manner, causing functional and structural changes in target proteins.
The Chemosensory Receptor Repertoire of a True Shark Is Dominated by a Single Olfactory Receptor Family
The Chemosensory Receptor Repertoire of a True Shark Is Dominated by a Single Olfactory Receptor Family Kanika Sharma, Adnan Syed, Sara Ferrando, Sylvie Mazan, Sigrun Korsching ABSTRACT: Throughout the animal kingdom chemical senses are one of the primary means by which organisms make sense of their environment. To achieve perception of complex chemosensory stimuli large
Identifying Priorities for Shark Conservation in the Bay of Bengal
Identifying Priorities for Shark Conservation in the Bay of Bengal, Bangladesh Mahatub Khan Badhon, Md Kutub Uddin, Fahmida Khalique Nitu, Enamul Mazid Khan Siddique ABSTRACT: Fisheries bycatch is known as the major threat to Threatened shark species (herein, sharks, skates, and rays) in Bangladesh. But bycatch is not appropriately addressed under the existing wildlife and
Impact of satellite linked radio transmitting tags on the dorsal fin of white sharks
Impact of satellite linked radio transmitting (SLRT) tags on the dorsal fin of subadult and adult white sharks (Carcharodon carcharias) Nasby-Lucas, Nicole; Domeier, Michael L ABSTRACT: Satellite linked radio transmitting (SLRT) tags provide long-term, high accuracy, near real time tracking data for marine wildlife. Adult white sharks, (Carcharodon carcharias Linnaeus, 1758) in the northeastern Pacific
Local drivers of declining shark fisheries in India
Local drivers of declining shark fisheries in India Divya Karnad, Dipani Sutaria, Rima W. Jabado ABSTRACT: This study evaluates local-scale drivers of shark harvests in India, one of the world’s largest shark fishing nations. Focusing on key harbours in the states of Gujarat and Maharashtra, which together contribute 54% of India’s shark harvest, this study
Shark Activity and Congestion of the Surfing Commons
Men in Grey Suits: Shark Activity and Congestion of the Surfing Commons Franklin G. Mixon Jr, Chandini Sankaran ABSTRACT: This study extends recent research on informal property rights at surf breaks by exploring the process through which nature, by establishing conditions conducive (or not) to the presence of sharks, shapes the baseline level of exploitation

Briscoe, Heidi Dewar, Elliott L. Hazen, Rebecca L. Lewison, Heather Welch, Larry B. Crowder ABSTRACT: Aim Animal tracking can provide unique insights into the ecology and
Testing a susceptibility threshold for risk promotion messages in the shark diving context
Testing a susceptibility threshold for risk promotion messages in the shark diving context Maria Knight Lapinski, Lindsay Neuberger, Katelyn Grayson-Sneed, Meredith L. Gore ABSTRACT: This paper presents the results of two experiments designed to test a susceptibility threshold in the shark cage diving context, positing that persons who are high relative to low sensation-seekers are
Accuracy of visual length estimates of white sharks
Published on 22 May 2019 Eyes on the size: accuracy of visual length estimates of white sharks, Carcharodon carcharias Cameron May, Lauren Meyer, Sasha Whitmarsh, Charlie Huveneers ABSTRACT: Visual estimates have been used extensively to determine the length of large organisms that are logistically challenging to measure. However, there has been little effort to quantify
A characterization of Australian shortfin mako shark anglers
Published on 04. June 2019 A characterization of Australian shortfin mako shark anglers R.P.French, J.M.Lyle, W.M.Twardek, S.J.Cooke, J.M.Semmens ABSTRACT: Understanding the human dimensions of recreational fisheries is critical to the development of effective fisheries management regulations. This study aimed to characterize Australian shortfin mako shark (Isurus oxyrinchus) anglers in terms of their gear use, perceptions
