Nitrogen (N) deposition can alter belowground microbial communities, especially ectomycorrhizal (ECM) fungi, resulting in a reduced ability of associated trees to access organic nutrients. This study tested whether N addition decreases ECM species richness and shifts ECM species composition across spatial scales in a subtropical slash pine (Pinus elliottii) plantation...

What are the origins of race-based affirmative action in college admissions? With only a few exceptions, there remain few evidence-based accounts of when and why such programs emerged among selective institutions of higher education; how heavily they weighed racial considerations; and how exactly race was taken into account.
