Coral Reefs on the Edge? Carbon Chemistry on Inshore Reefs of the Great Barrier Reef
While increasing atmospheric carbon dioxide (CO2) concentration alters global water chemistry (Ocean Acidification; OA), the degree of changes vary on local and regional spatial scales. Inshore fringing coral reefs of the Great Barrier Reef (GBR) are subjected to a variety of local pressures, and some sites may already be marginal habitats for corals. The spatial and temporal variation in direc...
متن کاملOptimising Land-Sea Management for Inshore Coral Reefs
Management authorities seldom have the capacity to comprehensively address the full suite of anthropogenic stressors, particularly in the coastal zone where numerous threats can act simultaneously to impact reefs and other ecosystems. This situation requires tools to prioritise management interventions that result in optimum ecological outcomes under a set of constraints. Here we develop one su...
متن کاملFunctional Roles of Sponges on Coral Reefs
ALTHOUGH a small group of carbonate excavating sponges can dismantle reefs, and some sponges can overgrow corals, it is now known that sponges also substantially benefit coral reefs and associated ecosystems. Sponges benefit reefs by efficiently filtering small (<5um) organic particles from the water column, binding live corals to the reef frame, facilitating regeneration of broken reefs, provi...
متن کاملDisturbance gradients on inshore and offshore coral reefs caused by a severe tropical cyclone
Tropical storms (cyclones, hurricanes, or typhoons) are the most severe form of mechanical disturbance of coral reefs. In 2005, severe tropical cyclone Ingrid crossed the far northern Great Barrier Reef, a region that had not been affected by a major disturbance for several decades, and where benthic data had been collected before the cyclone crossed. This storm provided a unique opportunity to...
متن کاملeffeCts on CorAl reefs
A hurricane (also tropical cyclone, typhoon) is a warm-core, low-pressure system that develops over tropical or subtropical waters. Most hurricanes form from a trough of low-pressure, over ocean surface temperatures greater than 26°C. As air moves across the ocean surface, it extracts moisture (water vapour) and energy (as a result of evaporation) from the ocean. The low pressure draws air inwa...
