Conservation Biology: Strict Marine Protected Areas Prevent Reef Shark Declines
نویسنده
چکیده
Populations of two coral reef shark species are declining rapidly: the pattern of decline highlights both the substantial impact of poaching on closed areas and the success of strict no-entry marine protected areas in maintaining healthy shark populations.

Ongoing Collapse of Coral-Reef Shark Populations
Marine ecosystems are suffering severe depletion of apex predators worldwide; shark declines are principally due to conservative life-histories and fisheries overexploitation. On coral reefs, sharks are strongly interacting apex predators and play a key role in maintaining healthy reef ecosystems. Despite increasing fishing pressure, reef shark catches are rarely subject to specific limits, wit...
متن کاملResidency and Spatial Use by Reef Sharks of an Isolated Seamount and Its Implications for Conservation
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. Currently, the Coral Sea area and its seamounts (north-east Australia) are under review to determine if MPAs are warranted. The protection of sharks at these seamounts should be an integral com...
متن کاملAssessing the effectiveness of a large marine protected area for reef shark conservation
Article history: Received 27 August 2016 Received in revised form 22 November 2016 Accepted 13 January 2017 Available online xxxx Large marine protected areas (MPAs) have recently been established throughout the world at an unprecedented pace, yet the value of these reserves formobile species conservation remains unclear. Reef shark populations continue to decline even within some of the larges...
متن کاملShark baselines and the conservation role of remote coral reef ecosystems
Scientific monitoring has recorded only a recent fraction of the oceans' alteration history. This biases our understanding of marine ecosystems. Remote coral reef ecosystems are often considered pristine because of high shark abundance. However, given the long history and global nature of fishing, sharks' vulnerability, and the ecological consequences of shark declines, these states may not be ...
متن کاملQuantifying Shark Distribution Patterns and Species-Habitat Associations: Implications of Marine Park Zoning
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. The present study examined shark distribution patterns, species-habitat associations, and marine reserve use with baited remote underwater video stations...
