Fish biodiversity protects coral reefs

Science Bulletins: Fish Biodiversity Protects Coral Reefs from AMNH on Vimeo. In tropical coral reefs, plant-eating fish and other herbivores support the dominance of the living coral by eating seaweed. Also known as macro algae, seaweeds create energy from sunlight through photosynthesis, like plants, and support much of the life in the sea. But they also compete with young corals…

Butcher, baker, and brewer. This image illustrates the strikingly simple but powerful analogy between man-made and natural systems. By looking at the functional structure of coral reef fish communities through a human eye, we find butchers, bakers, and brewers, but also diligent, cranky farmerfish, visually pleasing but ecologically negligible aesthetes, or worthless aristocrats. Using this approach, we can begin to answer some of the most pressing questions in coral reef biology. What are the origins and future trajectories of coral reefs and their fishy inhabitants? How do humans affect this perfectly balanced market? And do more brewers really make a happier system? Simon J. Brandl.

Butcher, baker, brewer-fish

We asked science café aspirants for creativity and Simon Brandl brought it with his analogy of division of labor in a coral reef community, where butcher-sharks course among the brewers, bakers, and aristocrats of the reef. Brandl shares the 2014 ESA Science Café Prize with co-winner Madhusudan Katti. He is a PhD candidate at the ARC Centre of Excellence for…

Looking to large tributaries for conservation gains

By Liza Lester, ESA communications officer Mississippi River Basin. Green tributaries have sufficient flow for large-river specialist fishes, and long stretches unobstructed by obstacles of civilization. Blue tributaries fall below a critical flow threshold. Yellow tributaries discharge enough water, but are blocked by dams. On big rivers like the Mississippi, the infrastructure of modern civilization – dams, locks, dikes, power…

Depression-era drainage ditches emerge as sleeping threat to Cape Cod salt marshes

Contemporary recreational fishing combines with old WPA project to hasten marsh die-off By Liza Lester, ESA communications officer CAPE Cod, Massachusetts has a problem. The iconic salt marshes of the famous summer retreat are melting away at the edges, dying back from the most popular recreational areas. The erosion is a consequence of an unexpected synergy between recreational over-fishing…

A yellow perch in murky water

Big fish, little fish, hump-shaped foraging curves, and the landscape of fear. by Liza Lester, ESA communications officer IN LIFE, much depends on context. The benefits accruing from the pursuit of liberty, lunch, and other forms of happiness, are tempered by the presence of risk. This is as true for small fishes as for anyone. In Lake Erie, young yellow…

Welcome to Sweden

No, not Greg Poehler’s short-lived international sitcom by the same name, but very literally what the hotel clerk said when I checked in. He smiled; since I’d been practicing on Duolingo for a few weeks and had hoped to proudly correctly pronounce Tack så mycket and instead replied (translated) “you’re welcome,” I did not. Blame the jet lag. Nonetheless, greetings from…
