Queer Birds Lyon & Eadie's observation (backed by a theoretical discussion and an analysis of ecological energetics) is that obligate parasitism is found almost exclusively in altricial birds whereas facultative parasitism is predominant in precocial birds. Precocial birds, on the other hand, generally invest too much energy and nutrients in their eggs (and the kids are less of a bother!) to be indiscriminate about where they leave them. Precocial birds tie up more resources in each egg and have to incubate for a longer time but when the young hatch they can soon move and are not, literally, sitting ducks. www.chebucto.ns.ca /Environment/NHR/queer.html   (1665 words)

1992 Ramon Magsaysay Awardee for Public Service - Angel C. Alcala From the moment Alcala began surveying the Philippine reefs in the early 1970s, he was confronted with brutal acts of ecological destruction, which had their roots in social and political forces that violated the serene world of pure research, just as they violated the reefs themselves. The marine laboratory Alcala founded is today in the good hands of his chosen successor, Dr. Hilconida Calumpong, a marine botanist and expert in sea energetics, trained at the University of California at Berkeley—the staunch rival (he likes to point out) of Stanford, his own alma mater. Alcala recorded the rising population of fish that colonized the faux-reefs and noted that only four to five months were needed to create a harvestable crop, as long as harvesting was kept at a sustainable 3 to 5 percent level. www.rmaf.org.ph /Awardees/Biography/BiographyAlcalaAng.htm   (63 words)

Energy Conservation in General While analyzing this problem Julius von Mayer formulated the idea of energy conservation and used it to understand energy flow not only through the human body but also throughout our ecological system. It is interesting that his discovery was prompted by careful consideration of the energetics of the human body. During a year he spent as a physician aboard a dutch merchant ship voyaging in tropical climates Dr. Mayer was perplexed by the observation that the arterial blood of newly arrived sailors was unusually red. www.pha.jhu.edu /~broholm/l14/node1.html   (400 words)
