The question of why males invest more into competition than offspring care is an age-old problem in evolutionary biology. On the one hand, paternal care could increase the fraction of offspring surviving to maturity. On the other hand, competition co

SummaryThe theory of selection of quantitative traits is widely used in evolutionary biology, agriculture and other related fields. The fundamental model known as the breeder’s equation is simple, robust over short time scales, and it is often poss

Metal-laden acid drainage from the reclaimed Landusky open-pit mine is thought to be the major source of environmental degradation to Swift Gulch, a small stream in the Little Rocky Mountains of north-central Montana. Ground water enters Swift Gulch

Interpretation of single-well tests with the Cooper-Jacob method remains more reasonable than most alternatives. Drawdowns from 628 simulated single-well tests where transmissivity was specified were interpreted with the Cooper-Jacob straight-line me

Slug tests performed in high transmissivity aquifers may exhibit underdamped inertial oscillatory behavior. Analytical methods for oscillatory data have been developed, but are mathematically intimidating. Spreadsheet modeling is helpful because read

Disinterested physical geology students can be enticed into performing an experiment that takes them though the scientific method and utilizes math skills if offered extra credit. The experiment causes students to compare the angle of repose of diffe

We face an increasingly wide range of threats to our marine, coastal and estuarine environments, many aggravated by human activity. Attempts to manage these problems in isolation are looking ever more ineffective and unaffordable, and over-prescripti
