A leading strategy in international efforts to reverse ongoing losses in biodiversity is the use
of protected areas. We use a broad range of data and a review of the literature to show that …

Marine biodiversity worldwide is under increasing threat, primarily as a result of over-
harvesting, pollution and climate change. Chondrichthyan fishes (sharks, rays and …

Tropical reef systems are transitioning to a new era in which the interval between recurrent
bouts of coral bleaching is too short for a full recovery of mature assemblages. We analyzed …

This report provides a detailed assessment of the status of and threats to the world's coral
reefs. It evaluates threats to coral reefs from a wide range of human activities, and includes …

A blind faith in the ability of MPAs to counteract loss of biodiversity is fraught with risk,
especially when MPAs are poorly planned and when the consequences of establishing …

We report a massive region-wide decline of corals across the entire Caribbean basin, with
the average hard coral cover on reefs being reduced by 80%, from about 50% to 10% cover …

The worldwide decline in coral cover has serious implications for the health of coral reefs.
But what is the future of reef fish assemblages? Marine reserves can protect fish from …

The decline of corals on tropical reefs is usually ascribed to a combination of natural and
anthropogenic factors, but the relative importance of these causes remains unclear. In this …

Overexploitation is one of the principal threats to coral reef diversity, structure, function, and
resilience [1, 2]. Although it is generally held that coral reef fisheries are unsustainable [3–5] …

A hierarchical sampling design, spanning five orders of magnitude (from 10s of metres to
100s of kilometres) was created in order to quantify the multi-scale spatial variability of …
