Moderne Nahrungsketten an Korallenriffen vor den Küsten der Dominikanischen Republik und Panamas sind etwa 60 bis 70 Prozent kürzer als vor rund 7.000 Jahren, berichten Forscher in Nature

>Some ancient fish in the Caribbean may have lost their lunch. 

>Modern food chains on coral reefs off the coasts of the Dominican Republic and Panama are roughly 60 to 70 percent shorter than they were around 7,000 years ago, researchers report February 11 in *Nature*. Habitat loss and overfishing may have pushed more species to compete for fewer resources and repositioned some fish groups within the ecosystem’s food chain.

>The findings suggest fish could be less able to adapt if food sources suddenly become scarce, perhaps making today’s reefs even more vulnerable in an already changing environment.

>“Understanding the food webs helps us understand the health of the reef,” says Jessica Lueders-Dumont, a fisheries ecologist and geochemist at Boston College in Chestnut Hill, Mass. “If we could go back, scuba dive on the same reefs a couple thousand years ago, what would they look like?”
