USGS To Study Young Forests And Streamsides In Western Oregon
...fungi,mollusks and bats. Ecosystem management is dictated by the Northwest Forest Plan, which was adoptedin 1994 because of long-standing public concerns over management of federal forest lands inwestern Washington, Oregon and northern California. The plan provides a basisfor regional-scale management of f...Chumminess Of Roundworms Linked To Single Gene, Offering Insight Into Mechanisms Of Social Behaviors
... the discovery that roundworms'feeding behavior is dictated by a single gene, for it calls into question theprevailing assumption that innate behaviors result from numerous genes acting inconcert, even in simpler species, such as fruit flies. The researchers examined 17 species of roundworm, collecte...Saturated fats: The very bad,the not-so-bad and the benign

However, little research has been done to distinguish the different types of saturated fats and their relative harmfulness to cardiovascular heal...Threatened Galapagos plants are focus of biologist's field guide

...iologists wondered: Are the gender-typical actions dictated by the animal's sex, as embodied in the gonads? Or can a brain process alone initiate gender-typical behavior? Working in the laboratory with anesthetized type I males, type II males and female midshipman fish, the Cornell biologists first applied g...Animals regulate their numbers by own population density

Because every molecular function of plants is dictated by DNA, an understanding of the genome could also help scientists develop crops that grow faster and larger, are more disease-resistant, and produce useful chemicals more efficiently. Arabidopsis researchers have also identified genes that determin...Scientists discover how nerve cells move from target to target as they wire up the developing embryo
...entists discovered that the axon's behavior is not dictated by the sum of all positive and negative signaling molecules. Rather, they found, the axon's receptors for the repellent molecule - a receptor dubbed Robo - physically block the performance of receptors for the attractive signal, in effect, silencing ...To suppress or not to suppress: Questioning the ponderosa pine model of forest fire management
...nt, large, lightening-caused, high intensity fires dictated the age distribution of trees commonly found in the area.

C. elegans are studied because they have a genetic makeup similar to humans. Because their systems are very small (about 950 cells make up an entire worm), ......s us that "the waxing and waning of all things are dictated by the laws of nature." Similarly, our moral likes and dislikes, as intense as they may appear at the moment, will dissipate and give way to the more fundamental principles that govern our behavior.

Evolution has generally dictated that it is usually the male that lavishes the female with expensive gifts (usually food) and often risks life and limb to secure the opportunity to pass on his genes to the next generation.
