Nonindigenous species invasions have caused disruptions of native communities and detrimental economic impacts to fisheries in many temperate marine areas. However, comparatively little information exists for tropical regions, and even less is known about occurrences and impacts of nonindigenous species 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...
متن کاملEcological Studies on Two Amphiprion Species in Maldivian Coral Reefs
Amphiprion clarkii and A. nigripes were found in coral reefs of three different atolls in the Maldives. A. clarkii was associated with five species of host anemones, but A. nigripes was only found in Heteractis magnifica. In few cases, both anemonefishes have utilized the same individual of H. magnifica. There was no significant correlation between the size of the anemones and the number of the...
