Spontaneous Mutation Accumulation in Daphnia pulex in Selection-Free vs. Competitive Environments.

Understanding the rates, spectra, and fitness effects of spontaneous mutations is fundamental to answering key questions in evolution, molecular biology, disease genetics, and conservation biology. To estimate mutation rates and evaluate the effect of selection on new mutations, we propagated mutation accumulation (MA) lines of Daphnia pulex for more than 82 generations and maintained a non-MA ...

Behavioral contrast in competitive and noncompetitive environments.

Three experiments examined the effects of opportunities for an alternative response (drinking) on positive behavioral contrast of rats' food-reinforced bar pressing. In both Experiments 1 and 2 the baseline multiple variable-interval schedules were rich (variable interval 10-s), and contrast was examined both with and without a water bottle present. In Experiment 1, the rats were not water depr...

Statistical evidence indicates that formal strategizing makes insignificant contributions to profits. First, formalization undercuts the value of strategizing. Second, nearly all managers hold very inaccurate perceptions of both their firms and their market environments. Third, no one can forecast accurately over the long term. Fourth, fundamental barriers make it very difficult to attain high ...
