The Relative Abundance and Occurrence of Sharks off Ocean Beaches of New South Wales, Australia
Biology, 2022 There is still limited information about the diversity, distribution, and abundance of sharks in and around the surf zones of ocean beaches. We used long-term and large-scale drone surveying techniques to test hypotheses about the relative abundance and ...

Olfaction Contributes to Pelagic Navigation in a Coastal Shark. [PDF]
, 2016 How animals navigate the constantly moving and visually uniform pelagic realm, often along straight paths between distant sites, is an enduring mystery. The mechanisms enabling pelagic navigation in cartilaginous fishes are particularly understudied.

Factors Affecting Shark Detection from Drone Patrols in Southeast Queensland, Eastern Australia
Biology, 2022 Drones enable the monitoring for sharks in real-time, enhancing the safety of ocean users with minimal impact on marine life. Yet, the effectiveness of drones for detecting sharks (especially potentially dangerous sharks; i.e., white shark, tiger shark ...

Relative abundance of pelagic sharks in the western North Atlantic Ocean, including the Gulf of Mexico and Caribbean Sea [PDF]
, 2007 Little information exists on the status of pelagic shark populations in the Atlantic Ocean, especially in the Gulf of Mexico and Caribbean Sea. We derived indices of relative abundance for pelagic sharks based on mandatory logbooks and observer reports ...

Reef‐wide evidence that the presence of sharks modifies behaviors of teleost mesopredators
Ecosphere, 2021 The idea that the presence of sharks impacts the behavior of mesopredatory reef fishes is controversial and lacks clear evidence at reef‐wide scales. We compared the abundance and behavior of these reef fishes in response to the presence of reef sharks ...

Residency and spatial use by reef sharks of an isolated seamount and its implications for conservation. [PDF]
PLoS ONE, 2012 Although marine protected areas (MPAs) are a common conservation strategy, these areas are often designed with little prior knowledge of the spatial behaviour of the species they are designed to protect.

Some like it hot: Repeat migration and residency of whale sharks within an extreme natural environment. [PDF]
PLoS ONE, 2017 The Arabian Gulf is the warmest sea in the world and is host to a globally significant population of the whale shark Rhincodon typus. To investigate regional whale shark behaviour and movements, 59 satellite-linked tags were deployed on whale sharks in ...
