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.

Quantifying shark distribution patterns and species-habitat associations: implications of marine park zoning. [PDF]

PLoS ONE, 2014
Quantifying shark distribution patterns and species-specific habitat associations in response to geographic and environmental drivers is critical to assessing risk of exposure to fishing, habitat degradation, and the effects of climate change.

Vulnerability of tropical fish communities across depth in the central Indian Ocean. [PDF]

Conserv Biol
Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

Evaluation of Shifts in the Potential Future Distributions of Carcharhinid Sharks Under Different Climate Change Scenarios

Frontiers in Marine Science, 2022
Climate change is currently considered one of the main phenomena affecting marine species through expansion or contraction of their distribution. Being ectothermic organisms, sharks of the family Carcharhinidae could be highly susceptible to the effects ...

Comparative Space Use of Sympatric Sharks at a Remote Island in the South Pacific Ocean. [PDF]

Ecol Evol
The space use of 34 dusky (Carcharhinus obscurus), 32 Galapagos (C. galapagensis), 47 tiger (Galeocerdo cuvier), and 20 sandbar (C. plumbeus) sharks was monitored with acoustic telemetry between 2021 and 2024 in coastal waters around Norfolk Island, Australia, a remote small island in the southwestern Pacific Ocean.

Long-term changes in species composition and relative abundances of sharks at a provisioning site. [PDF]

PLoS ONE, 2014
Diving with sharks, often in combination with food baiting/provisioning, has become an important product of today's recreational dive industry. Whereas the effects baiting/provisioning has on the behaviour and abundance of individual shark species are ...

Tubbataha Reefs Natural Park: the first comprehensive elasmobranch assessment reveals global hotspot for reef sharks

Journal of Asia-Pacific Biodiversity, 2019
Elasmobranchs are experiencing population declines worldwide because of anthropogenic stressors. Marine protected areas (MPAs) have been shown to benefit mesopredatory species of shark.

Clarifying the Labrisomus Conundrum: Deep Divergence, Cryptic Lineages, and a Genetic Melting Pot in the Atlantic Ocean (Teleostei, Labrisomidae)

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim We evaluate the phylogenetic relationships and taxonomic validity of Atlantic species of Labrisomus, identifying the lineages currently assigned to L. nuchipinnis, and assessing the role of biogeographic barriers in shaping the evolutionary history and geographic distribution of the genus. Location Atlantic Ocean.
