Reproductive Biology of the Bonnethead (Sphyrna tiburo) from the Southeastern U.S. Atlantic Coast
… and recreational fisheries. Bonnetheads (Sphyrna tiburo) are a component of the small coastal shark (SCS) fishery complex, and are caught regularly in both types of fisheries. Despite being well studied in the Gulf of Mexico, little is known about bonnetheads from the U.S. Atlantic coast. …

Investigating single and multiple species fisheries management: stock status evaluation of hammerhead (Sphyrna spp.) sharks in the western North Atlantic Ocean and Gulf of Mexico
Three hammerhead sharks (Sphyrna spp.) are currently managed as part of the large coastal shark complex in the United States. Including multiple species in an assessment ignores the different stock dynamics of each individual species within the complex due to different life histories. This study …

Characterization of Andrenocortical Tissue Morphology, Histology, and Steroid Synthesis Among Finetooth (<i>Carcharhinus isodon</i>), Blacktip (<i>Carcharhinus limbatus</i>), Atlantic Sharpnose (<i>Rhizoprionodon terraenovae</i>), and Bonnethead (<i>Sphyrna tiburo</i>) Sharks
… terraenovae</em>, and Bonnethead <em>Sphyrna tiburo</em>. Morphological analysis revealed differences in interrenal structures among species. Finetooth and Blacktip Sharks have numerous discrete white interrenal bodies along the dorsal midline of the kidney. The Atlantic Sharpnose …

Heavy Metal Distribution Across Three Georgia Estuaries Using Coastal Sharks As Sentinel Species
… Contrary to predictions, Bonnethead (<em>Sphyrna tiburo</em>) showed no differences in their blood THg concentrations among estuaries (p = 0.115). However, there were species-specific differences, with THg concentrations in Atlantic Sharpnose (<em>Rhizoprionodon terraenovae</em>) being …

Influence of the Estimator Selection in Scalloped Hammerhead Shark Stock Assessment
In natural sciences, frequentist paradigm has led statistical practice; however, Bayesian approach has been gaining strength in the last decades. Our study assessed the scalloped hammerhead shark population on the western North Atlantic Ocean using Bayesian methods. This approach allowed …
