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…

These are not your urban lawn flamingos! This pair dancing in the low tide in Mumbai’s busy harbor are Lesser Flamingos, considered near-threatened species due to declining populations in Africa and India. Yet, over the past decade, some 10-25 thousand of them have been turning up in Mumbai’s Thane Creek to spend the winter right in the middle of a megacity of over 20 million people. I photographed this pair just a year ago at Sewri Port, an industrial dockyard area known more for repairing boats than harboring such wildlife which now teems in the creek’s recovering mangroves.
