A multifaceted citizen-science approach for characterizing shark depredation in Florida’s recreational fisheries Open
Depredation (i.e. partial removal of target catch prior to retrieval) caused by sharks is a prevalent issue affecting several fisheries in the southeastern USA. While US fisheries managers have begun monitoring shark depredation in commerc…

Multi-year assessment of immature bull shark Carcharhinus leucas residency and activity spaces in an expansive estuarine nursery Open
Although portions of the Indian River Lagoon (IRL), Florida (USA), serve as essential fish habitat for US Atlantic coast bull sharks Carcharhinus leucas , past studies were short-term (days to months) and encompassed only small parts of th…

Overwinter habitat use of young-of-the-year white sharks (Carcharodon carcharias) off the eastern United States Open
Despite recent increases in the number of studies that have focused on the movements and habitat use of juvenile and adult white sharks (Carcharodon carcharias) in the Northwest Atlantic Ocean off the eastern United States, there is compar…

Three-Dimensional Movements and Habitat Selection of Young White Sharks (Carcharodon carcharias) Across a Temperate Continental Shelf Ecosystem Open
As highly mobile predators with extensive home ranges, some shark species often utilize a continuum of habitats across the continental shelf ranging from the surf zone to the open ocean. For many species, these cross-shelf distributions ca…

Genetic evidence supports a range extension for the Brazilian cownose ray <span><i>Rhinoptera brasiliensis</i></span> in the western North Atlantic Open
We report 24 new records of the Brazilian cownose ray Rhinoptera brasiliensis outside its accepted geographic range. Sequencing of a 442‐base pair portion of the mitochondrial NADH dehydrogenase subunit 2 gene for 282 Rhinoptera samples re…

Performance of Two Survey Gears Targeting Elasmobranchs in a Shallow, Subtropical Estuary Open
Fishery-independent surveys have become increasingly prevalent in recent decades for monitoring the population trends of highly mobile species like elasmobranchs (sharks and rays). Despite the utility of gear evaluations for streamlining c…

First insights into the movements of young-of-the-year white sharks (Carcharodon carcharias) in the western North Atlantic Ocean Open
In recent years, white sharks ( Carcharodon carcharias ) have become more accessible to researchers off the northeastern U.S. as feeding aggregation sites have emerged and the population has increased. However, there has been limited resea…

Diel Activity Patterns and Movement of Invasive Lionfish (Pterois volitans/P. miles) in the Florida Keys Identified Using Acoustic Telemetry Open
The invasion of Indo—Pacific lionfish (Pterois volitans/P. miles) throughout the Caribbean and southeastern U.S. Atlantic represents a significant ecological threat, yet few studies have examined the daily activity and movement patterns of…
