In This Issue: Views from Above and Below

Untangling positive and negative biotic interactions: views from above and below ground in a forest ecosystem.

In ecological communities, the outcome of plant-plant interactions represents the net effect of positive and negative interactions occurring above and below ground. Untangling these complex relationships can provide a better understanding of mechanisms that underlie plant-plant interactions and enhance our ability to predict population, community, and ecosystem effects of biotic interactions. I...

of state below and above

A unique parameterization of the QCD equation of state below and above T c We present a unique parameterization of the equation of state of strongly interacting matter in the temperature interval 0.6T c · · · 3T c at µ = 0 within a quasi-particle model based on quark and gluon degrees of freedom. The extension to non-vanishing baryon-chemical potential is discussed.
