Theory and experiments indicate that changes in consumer diversity affect benthic community structure and ecosystem functioning. Although the effects of consumer diversity have been tested in the laboratory and the field, little is known about effects of consumer diversity in the subtidal zone, one of the largest marine habitats. We investigated the grazing effects of sea urchins on algal abundance and benthic community structure in a natural subtidal habitat of the Galápagos Islands.

- - The conservation status of 845 reef-building coral species was evaluated, revealing that 32.8% of the 704 assessed species are at a high risk of extinction due to factors like bleaching and diseases caused by rising sea temperatures.
- - Human activities also worsen the risk of coral extinction, and the overall threat level for corals has significantly increased in recent decades compared to most land species.
- - The Caribbean region has the highest percentage of corals in dangerous extinction categories, while the Coral Triangle has the largest number of species facing elevated extinction risks, highlighting the urgent need for effective coral conservation efforts.
Many species vary in their ecology across their geographic ranges in response to gradients in environmental conditions. Such variation, which can influence life history traits and subsequent demography of populations, usually occurs over large spatial scales. However, describing and understanding the causes of such variation is difficult precisely because it occurs over such large spatial scales.
