Larval orientation to reefs and reef sound

The Journal of the Acoustical Society of America, 2002
Reef systems form a discontinuous spatial mosaic leading many reef organisms to have a dispersal phase in their early life history. At the end of this phase, the larvae must settle onto a reef. Recent evidence supports the view that both larval fish and invertebrates are more active participants in finding suitable settlement habitat than had ...

Reefs and Reef Environments: ABSTRACT

AAPG Bulletin, 1969
Reefs are considered as largely unbedded or obscurely bedded, massive structures which are composed of solid, organically bound, in situ organisms, and which were at least potentially wave-resistant structures that rose topographically above the surrounding depositional surface.

Year of the Reef

Science, 2007
The coral reefs of the world, on which the news focus section of this issue of Science concentrates, are important for all sorts of reasons. For many, exploration by diving provides a unique connection with a fascinating natural ecosystem. For scientists, including climate scientists, the health of reefs provides insight into the physical and ...

Reef-growth model for Silurian pinnacle reefs, northern Michigan reef trend

Geology, 1979
Pinnacle reefs of the Niagara Group in northern Michigan are located on a paleotopographic ramp basinward of a massive shelf-edge reef complex. The reefs increase in height from 90 m near the shelf to 180 m at the basinward limit. The more basinward pinnacles initiated in deep water as carbonate mud mounds.

Artificial Reefs: The Importance of Comparisons with Natural Reefs

Fisheries, 1997
Abstract Methods used to evaluate the performance of an artificial reef will vary according to the purpose for which the reef was built. To determine how well artificial reefs mitigate losses due to human activities on natural reefs, the performance of artificial reefs should be evaluated using contemporaneous comparisons with relatively undisturbed ...

Rebuilding coral reefs: does active reef restoration lead to sustainable reefs?

Current Opinion in Environmental Sustainability, 2014
The coral reefs worldwide are exposed to multiple anthropogenic threats and persisting global change impacts, causing continuous degradation, also calling for the development of novel restoration methodologies. Of the most promising emerging approaches, deriving its rationale from silviculture, is the low-cost ‘gardening concept’, guided by a two-step ...

The mid-shelf reefs of the Great Barrier Reef

2007
Introduction The evolutionary classification for coral reefs of Hopley (1982), although applied elsewhere, was initially devised specifically for the reefs of the Great Barrier Reef (GBR). The classification (Figs. 5.6 and 5.7, Table 5.3) shows antecedent platforms being recolonized, with reef growth during initial juvenile stages being largely ...

The architects of a reef

2014
Abstract Coral reefs are tropical ecosystems but show global patterns. The Caribbean has about 60 reef-building coral species, while Southeast Asia has nearly 1,000, this number broadly diminishing with distance east and west from the Southeast Asian region. Diversity of corals also diminishes broadly with distance north and south of the
