Elevated sea surface temperatures drive greater seasonal depth use in a baited aggregation of silky sharks Carcharhinus falciformis Open
Conservation plans for pelagic sharks in future climate scenarios are limited by a lack of empirical data on behavioral responses to sustained elevated temperatures. The relatively high sea surface temperatures observed in the Red Sea prov…
Just keep swimming? Observations of resting behavior in gray reef sharks <span><i>Carcharhinus amblyrhynchos</i></span> (Bleeker, 1856) Open
Understanding the respiratory modes of sharks has important implications for studying the metabolism, energetics, and behavioral strategies of different species. Here we provide the first reported observations of resting behavior in the gr…
Using Global Red List Data to Inform Localised Research and Conservation Priorities—A Case Study in the Republic of Seychelles Open
Global Red List assessments are powerful tools for informing large-scale conservation decision-making processes, however, they can also be used to inform more localised research and conservation priorities. Here, a conservation status asse…
Stingray Habitat Use Is Dynamically Influenced by Temperature and Tides Open
Abiotic factors often have a large influence on the habitat use of animals in shallow marine environments. Specifically, tides may alter the physical and biological characteristics of an ecosystem while changes in temperature can cause ect…
Ontogenetic Shifts in Home Range Size of a Top Predatory Reef-associated Fish (Caranx ignobilis): Implications for Conservation. Open
Defining the home range of vulnerable species is critical for designing effective spatial management strategies. However, animal home ranges often change with ontogeny and quantifying the associated temporal and spatial changes is particul…
At the Turn of the Tide: Space Use and Habitat Partitioning in Two Sympatric Shark Species Is Driven by Tidal Phase Open
Coexistence of ecologically similar species occupying the same geographic location (sympatry) poses questions regarding how their populations persist without leading to competitive exclusion. There is increasing evidence to show that micro…
The complete mitochondrial genome of a gray reef shark, <i>Carcharhinus amblyrhynchos</i> (Carcharhiniformes: Carcharhinidae), from the Western Indian Ocean Open
We present the mitochondrial genome sequence of a gray reef shark, Carcharhinus amblyrhynchos (Bleeker 1856), a coral reef associated species. This is the first mitogenome for this species from the western Indian Ocean. The mitogenome is 1…
Refuges and risks: Evaluating the benefits of an expanded <span>MPA</span> network for mobile apex predators Open
Aim Concurrently, assessing the effectiveness of marine protected areas and evaluating the degree of risk from humans to key species provide valuable information that can be integrated into conservation management planning. Tiger sharks ( …
Migratory behaviour and spatial dynamics of large sharks and their conservation implications Open
Determining the dynamic nature of animal movement has been an important component in a wider understanding of animal population ecology. Generally, this is because temporal change in the density of a population at a specific geographic loc…
Acoustic telemetry and network analysis reveal the space use of multiple reef predators and enhance marine protected area design Open
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. We used l…
