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.

The Phenomenon of Piebaldism in Sharks: A Review of Global Sightings and Patterns. [PDF]

Ecol Evol
Chromatic disorders like piebaldism—a rare form of leucism causing partial pigment loss—have been documented in 25 wild shark cases across 17 species and 11 families, with varying anatomical distribution. This study compiles published and unpublished records to better understand the taxonomic and geographical spread of piebaldism and its potential ...

Location, Location, Location! Evaluating Space Use of Captive Aquatic Species—A Case Study with Elasmobranchs

Journal of Zoological and Botanical Gardens, 2022
The space use of captive animals has been reliably used as a tool to measure animal welfare in recent years. However, most analyses of space use focus primarily on terrestrial animals, with very little emphasis placed on the space use of aquatic animals.

Effects of protection on large-bodied reef fishes in the western Indian Ocean. [PDF]

Conserv Biol
Abstract Predatory and large‐bodied coral reef fishes have fundamental roles in the functioning and biodiversity of coral reef ecosystems, but their populations are declining, largely due to overexploitation in fisheries. These fishes include sharks, groupers, Humphead wrasse (Cheilinus undulatus), and Green Humphead parrotfish (Bolbometopon muricatum).

Defining distribution and habitat use of west‐central Florida’s coastal sharks through a research and education program

Ecology and Evolution, 2021
Identifying critical habitat for highly mobile species such as sharks is difficult, but essential for effective management and conservation. In regions where baseline data are lacking, non‐traditional data sources have the potential to increase ...

Human‐induced shifts in habitat use and behaviour of a marine predator: the effects of bait provisioning in the blacktip reef shark

Animal Conservation, 2020
While the negative effects of consumptive pressures on marine predators are well established, the effects of increasing non‐consumptive activities such as wildlife tourism are still understudied. As such, the long‐term effects of the provision of bait on

Speed-dependent locomotor patterns during steady swimming in a demersal shark. [PDF]

J Fish Biol
Abstract Swimming ability is critical for navigating complex benthic habitats, yet the biomechanical strategies demersal sharks employ to modulate body and fin movements across varying speeds remain largely unexplored. This study examines speed‐dependent kinematic patterns in the small‐spotted catshark (Scyliorhinus canicula), a benthic species with ...

Blacktip reef sharks (Carcharhinus melanopterus) show high capacity for wound healing and recovery following injury [PDF]

Conservation Physiology, 2015
Wound healing is important for sharks from the earliest life stages, for example, as the 'umbilical scar' in viviparous species heals, and throughout adulthood, when sharks can incur a range of external injuries from natural and anthropogenic sources. Despite anecdotal accounts of rapid healing in elasmobranchs, data regarding recovery and survival of ...

Acoustic telemetry and network analysis reveal the space use of multiple reef predators and enhance marine protected area design [PDF]

, 2016
Marine protected areas (MPAs) are commonly employed to protect ecosystems from threats like overfishing. Ideally, MPA design should incorporate movement data from multiple target species to ensure sufficient habitat is protected.
