Migration is common in marine animals, 1–5 and use of the map-like information of Earth's
magnetic field appears to play an important role. 2, 6–9 While sharks are iconic migrants 10 …

The Squalus genus comprises a group of small demersal sharks occurring circumglobally,
popularly known as dogfish sharks. This genus exhibits a conserved morphology, thus …

Patterns of genetic connectivity can be used to define the geographic boundaries of fishes
and underpin management decisions. This study used a genetic multi-marker approach to …

Resolving the identity, phylogeny and distribution of cryptic species within species
complexes is an essential precursor to management. The bonnethead shark, Sphyrna …

The age, growth, and maturity of bonnetheads, Sphyrna tiburo, inhabiting estuarine and
coastal waters of the US Gulf of Mexico (GOM) were investigated. Based on results of a …

The bonnethead Sphyrna tiburo is a wide-spread, small species of coastal hammerhead
shark with a long history of taxonomic uncertainty, including, according to some authors …

Bonnethead and Caribbean sharpnose sharks frequent coastal waters, rendering them
vulnerable to overexploitation, with the bonnethead shark listed as endangered by the …

The apparent lack of physical barriers in the marine realm has created the conception that
many groups have a constant gene flow. However, changes in ocean circulation patterns …

Gene flow is important for maintaining the genetic diversity required for adaptation to
environmental disturbances, though gene flow may be limited by site fidelity in small coastal …

Globally, hammerhead sharks have experienced severe declines owing to continued
overexploitation and anthropogenic change. The smooth hammerhead shark Sphyrna …
