Strong case for seagrass in biodiversity analysis
A new analysis of a key contributor to the marine food web has turned up a surprising twist: more unique species in cooler waters than in the tropics, a reversal of the situation on land. The findings highlight the need to direct limited conservation dollars according to science, with a focus on places where biodiversity is most at risk, said Barnabas Daru, Harvard Herbaria Postdoctoral Fellow in Organismic and Evolutionary Biology, who performed the analysis on the world’s 70 species of seagrass. Daru acknowledged that seagrass isn’t as exciting as sharks or tuna, or as marine mammals such as seals, dolphins, and manatees. But for anyone who cares about the health of marine animals, he said, the role of humble seagrass at the beginning of the marine food chain is key. “The focus is often on animals, but anything that affects plants will have a cascading effect on everything higher up in the...
