Fine Roots, Net Primary Production, and Soil Nitrogen Availability: A New Hypothesis
TL;DR: In this article, the relationship between above-and belowground net primary production and soil nitrogen availability was studied at nine temperate forest sites, where annual allocations of nitrogen (N) and Net Primary production to leaf litter, perennial tissues (wood + bark), and aboveground biomass all increased significantly (P <.01) in relation to apparent N uptake by vegetation.

Directed evolution of a thermostable esterase
TL;DR: In vitro evolution is used to probe the relationship between stability and activity in a mesophilic esterase and indicates that these properties are not inversely correlated, which is a positive sign for enhanced thermostability.

A profile zonation for seasonal sand beaches from wave climate
TL;DR: In this paper, the seafloor profile of a seasonal sand beach is divided into three submarine zones parallel to the shoreline, and the shoal zone boundaries are defined based on critical values of two Froude numbers giving distinct thresholds in sand mobilization by waves.
