Rapid evolution in response to drought in just three short generations

Although we usually think about evolution taking thousands of years to occur, we find that evolution can be quite rapid and influence interactions between plants and microbes in the soil.

Are Darwin’s finches the only, or even the best, model of evolution among competitors?

We expect competitors to evolve to use distinct niches, but is that really how evolution happens in real communities?

Does a system play by the rules, or is its behavior random?

Do you want to be able to predict the behavior of an object or a system? If so, you need to know if the system is random or if it follows a set of rules. In our work, we use patterns in data to determine whether or not a system is random. We can even tell what kinds of rules the system follows.

Fishing for angler beliefs on goliath grouper

For more than 20 years, goliath grouper have been protected in U.S. waters. Recently, many anglers have been pressuring fishery managers to lift the harvest ban. We sought to measure the proportion of anglers interested in opening the fishery and why, and to examine how much they are willing to pay.

In one of nature's innovations, a single cell smashes and rebuilds its own genome

Even a single cell can pack a few surprises. The pond-dwelling, single-celled organism Oxytricha trifallax has the remarkable ability to break its own DNA into nearly a quarter-million pieces and rapidly reassemble those pieces when it's time to mate, a study led by Princeton researchers found.

Conservation versus innovation in the fight against antibiotic resistance

Maintaining effective antibiotics means conserving existing drugs, but people have little incentive to use antibiotics wisely, a Princeton researcher writes. Proposed increases in public subsidies for new antibiotics should be matched by greater spending on conserving existing antibiotics.
