In animals, reproductive behaviors serve to attract individuals together during the
breeding season and to coordinate the behavioral and physiological states of individuals
so that mating can successfully occur. In snakes, the various reproductive behaviors
including courtship, mating, courtship inhibition, male combat and trailing are mediated
primarily by pheromones. Pheromones...
In the highly competitive animal protein market, seafood faces increasing pressure to improve and standardize product quality.

could not itself remain unaffected. In the second half of
the nineteenth century, the subject of evolution was as

However, there have been limited studies of the fatigue behavior of small cracks in silicon nitride and other materials toughened...

Much of the Columbia River Basin has been cultivated for agriculture, which has reduced and fragmented the native shrub-steppe habitats. As a result, the range of the Washington ground squirrel (Spermophilus washingtoni) has been significantly reduced, prompting the states of Washington and Oregon to review their status. Consequently, I investigated...
