A cool new NutNet paper on field and lab based nitrogen mineralization across global grasslands

With a couple relatively easy to measure variables in the field, it is possible to convert lab-based potential N mineralization to in situ mineralization. Here's the summary from Risch et al. (2019) Nature Communications:

Experimental drought reduces genetic diversity in black grama

From the abstract: Understanding the resistance and resilience of foundation plant species to climate change is a critical issue because the loss of these species would fundamentally reshape communities and ecosystem processes. High levels of population genetic diversity may buffer foundation species against climate disruptions, but the strong selective pressures associated with climatic shifts may also rapidly reduce such diversity. We characterized genetic diversity and its responsiveness to experimental drought in the foundation grass, black grama (Bouteloua eriopoda).
