Habitat Complexity: Coral Structural Loss Leads to Fisheries Declines
Direct human impacts and global climate change are altering the composition and structure of coral reef habitats. These changes are simplifying size-abundance relationships of reef fish communities, reducing productivity through the system and ultimately threatening fisheries yields.
متن کاملVulnerability of Coral Reef Fisheries to a Loss of Structural Complexity
Coral reefs face a diverse array of threats, from eutrophication and overfishing to climate change. As live corals are lost and their skeletons eroded, the structural complexity of reefs declines. This may have important consequences for the survival and growth of reef fish because complex habitats mediate predator-prey interactions [1, 2] and influence competition [3-5] through the provision o...
متن کاملCryptic effects of habitat declines: coral-associated fishes avoid coral-seaweed interactions due to visual and chemical cues
Seaweed-dominated coral reefs are becoming increasingly common as environmental conditions shift away from those required by corals and toward those ideal for rampant seaweed growth. How coral-associated organisms respond to seaweed will not only impact their fate following environmental change but potentially also the trajectories of the coral communities on which they rely. However, behaviora...
متن کاملSpecialization in habitat use by coral reef damselfishes and their susceptibility to habitat loss
While it is generally assumed that specialist species are more vulnerable to disturbance compared with generalist counterparts, this has rarely been tested in coastal marine ecosystems, which are increasingly subject to a wide range of natural and anthropogenic disturbances. Habitat specialists are expected to be more vulnerable to habitat loss because habitat availability exerts a greater limi...
متن کاملMeasuring Structural Complexity on Coral Reefs
Structural complexity on coral reefs has been shown to positively influence several measures of biodiversity, and is thus an important ecological variable. The dominant field method used by reef scientists to measure structural complexity is the chain-and-tape method, which produces a measure of rugosity calculated as the ratio of contour–following vs. straight distance between two points on th...
