Hawaiian Petrel. Photo from Jim Denny on Flickr. Meet The Hawaiian Petrel (or ʻUaʻu or Pterodroma sandwichensis) a bird species endemic to the Hawaiian Islands but with an appetite causing it to dine on squids, fish, and crustaceans from around the Pacific. A single individual may take off on a 10,000 kilometer (>6,000 mile) trip . . . → Read More: An overfishing story told by bird collagen

Carbon, diatom, frustules, phytoplankton, Scientist In Residence Dear Diatoms, You are pretty, and I like you. Haeckel liked you too, so did Gaudi. Obviously, they appreciated the little things in life. While you still make appearances now and again in modern life, let’s face it: being microscopic and aquatic, recognition is an up-current battle, and you can’t swim. Perhaps obscurity suits you? . . . → Read More: Scientist In Residence: Danny Richter on the To Humble Diatom

Majority consensus makes me shudder. I just like rooting for underdogs*. Those undersea ridges at the boundaries of tectonic plates, spewing molten magma to form new crust are o’ so popular these days. Spreading plate boundaries…meh. What I do like is new research basically stating, and I am paraphrasing here, that spreading . . . → Read More: I Like Sills But Not A Fan Of The Popular Or My Friend’s Ex

For a while it was assumed that the anemones mainly persisted by utilizing carbon translocated from its symbionts, called autotrophy, but they can may supplement this by heterotrophic feeding on plankton. A study by Bachar and colleagues followed . . . → Read More: Determining the Fate of Carbon in a Mixotrophic Anemone

The report comes from a talk at The Ocean Science meeting in Portland last week discussing some calculations presented by Dr. Andrew Pershing on how whaling is putting “locked up” carbon back into the atmosphere. “Whales, like any . . . → Read More: Won’t They Think of the Poor Bone-Eating Worms?
