In spite of the wealth of research on the Great Barrier Reef, few detailed biodiversity assessments of its inshore coral communities have been conducted. Effective conservation and management of marine ecosystems begins with fine-scale biophysical assessments focused on diversity and the architectural species that build the structural framework of the reef. In this study, we investigate key cor...

White sharks (Carcharodon carcharias) are threatened apex predators and identification of their critical habitats and how these are used are essential to ensuring improved local and ultimately global white shark protection. In this study we investigated habitat use by white sharks in False Bay, South Africa, using acoustic telemetry. 56 sharks (39 female, 17 male), ranging in size from 1.7-5 m ...

The thirteen stations in Series A were visited at various times during the summer, and consequently the results do not represent a continuous proffie. They indicate that water movements of a very fundamental sort take place. This is especially noticeable in the vicinity of the slope, where the influence of oceanic water varies over many miles, extending considerably further inshore at some time...

This paper presents the first complete data of global downwelling irradiance (Ed) and the diffuse attenuation coefficient (K,,) for solar ultraviolet-B (UVB; 280 to 320 nm) in tropical waters. The penetration of solar UVB into shallow (0 to 5 m) seawater a t 3 sites in the central Indian Ocean and Andaman Sea, adjacent to areas of coral reefs. 1 t . d ~ studied using a semi-submersible scanning...

Reproductive activity of Red Snapper Lutjanus campechanus (Poey, 1860) at artificial reefs (ARs) are only recently being investigated. Yet, the management fishery differs on a regional basis with state and federal jurisdictions, reproductive differences among regions have not been To compare L. (inshore) (offshore) individuals were collected in northwestern Gulf Mexico from four ARs quarterly f...

Small-scale fisheries (SSF) in England face several challenges to their viability. We argue that the source of these can be traced more dominant large-scale (LSF) sector which has influence than SSF over government policies. A recent attempt mitigate impact been made by Future Inshore Fisheries initiative whose main prescription is co-management, i.e., giving a participatory role with and LSF d...
