In Chapter 4, I show that benthic and fish communities across the northwestern Caribbean are largely homogenized as a result of human disturbance. The exception is fish communities in large, no-take marine reserves, which resemble relatively healthy communities of low-impacted reefs in the Pacific....

F To find answers for these problems, scientists and researchers study the various factors that impact reefs. The list includes the ocean's role as a carbon dioxide sink, atmospheric changes, ultraviolet light (紫外线光) , ocean acidification, viruses, impacts of dust storms carrying agents to ...
In recent years, however, coral reefs have faced increasing threats from human activities and environmental factors, putting their survival at risk. One of the key ecological values of coral reefs lies in their role as habitats for marine organisms. As one of the most biodiverse ecosystems in ...
Attempts have been made to explain the sudden increases in Acanthaster populations since the mid-1950s and their impact on coral reefs. Answer Choices O Larvae Acanthaster populations have preyed on coral reefs and caused the loss of coral cover over large areas and the collapse of some coral ...
Coral reefs provide a range of medicinal compounds that are used to treat a variety of illnesses, including cancer, HIV, and Alzheimer's disease. The loss of coral reefs can result in the loss of these compounds, which can impact the development of new medicines. Additionally, the loss ...
Human impact increasingly alters global ecosystems, often reducing biodiversity and disrupting the provision of essential ecosystem services to humanity.
