... However, in Chapter 1, Jeremy Jackson compiles evidence from four major marine realms -- estuaries and coastal areas, continental shelves, open ocean pelagic zone, and coral reefs -- that marine ecosystems are under extreme duress from the oft-synergistic effects of habitat destruction, overfishing, introduced species, warming and acidification, toxins, and nutrient runoff. One common result has been the degradation of biodiverse marine ecosystems with complex food webs capped by an abundance of top-echelon predators into simplified biotic communities increasingly dominated by smaller animals, algae, and microbes.

... as a model taxon to assess global hotspots of extant biodiversity, endemism, and extinction risk, the intent being to identify evolutionary sources and sinks of stomatopod diversity, infer driving mechanisms, and provide an additional focus for conservation and management efforts on coral reefs. Stomatopod species diversity (like that of several other reef-dwelling marine taxa)
From page 3...
... They also conclude that parasite species diversity does not map linearly onto host species diversity, and that approximately three-quarters of all links in food webs involve a parasitic species. These findings provide a sobering reminder that the current extinction pulse is affecting many kinds of organisms (not just the conspicuous megafauna)
