Simulation-based evaluation of reserve network performance for Southern Dogfish

Simulation-based evaluation of reserve network performance for Centrophorus zeehaani (Centrophoridae): a protected deep-sea gulper shark Ross K Daley, Alistair J Hobday, Jayson M Semmens ABSTRACT: Resource use and conservation objectives can conflict where protected species and commercially fished species occur together. We tested the potential for a previously overfished deep-sea shark (Centrophorus zeehaani) with very

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
