...fatty-acid craze threatening our ecosystem? The best omega-3 source is oily fish like salmon, mackerel and sardines. Environmentalists fear that some species - especially a small filter feeder called menhaden, which plays a critical role in the aquatic food chain - are being overfished for oil supplements. Bigger fish prey on menhaden, which eat omega-3-rich algae and in doing so clean the ocean waters off the Atlantic and Gulf coasts. By filtering up to 7 gal. (about 26 L) per min., menhaden help prevent oxygen-depleting algal blooms that lead to underwater dead zones...
...their ecosystem parable, the Spierigs show they have minds that can invent a plausible society, and quite the eye for decorating their imaginary landscape, but no gift for bringing individual scenes and characters to life. The movie gets logy in its middle sections, and the sound recording makes it seem that everyone spoke into steel drums. Most of the actors are like plasticene puppets on a stop-motion movie set; their creators were so dazzled by their skills at art direction that they forgot to animate the figures. In standard-narrative terms, Daybreakers suffers from tired blood. No question...
...other co-authors, including scientists at Climate Central in Palo Alto and the California Academy of Sciences in San Francisco, emphasize that their velocity maps are oversimplifications - at least so far. For one thing, they do not account for the unique characteristics of various species within a given ecosystem. Some species may have more tolerance for climate changes than others, and may not need to move as quickly; some species may be intolerant of change but unable to move. Other species may be sensitive to changes in rainfall, while still others responsive only to temperature - and changes in these weather...
...Zofnass ’69 has made a $500,000 donation to the Harvard Museum of Natural History—the largest gift the Museum has received since its inception in 1998—for a new exhibit depicting the interactions that take place in a New England forest ecosystem...
...enough that we have the pollution and ghost nets that kill our marine life. I wasn't aware the loss of tuna would set the ocean's ecosystem out of balance. Thanks for the list "What You Can Do." Nature can rebound if given a chance. Donna Snow, OLYMPIA, WASH...
