Environmental Drivers of Holocene Forest Development in the Middle Atlas, Morocco

open access: yesFrontiers in Ecology and Evolution, 2017
In semi-arid regions subject to rising temperatures and drought, palaeoecological insights into past vegetation dynamics under a range of boundary conditions are needed to develop our understanding of environmental responses to climatic changes. Here, we

High functional diversity is related to high nitrogen availability in a deciduous forest - evidence from a functional trait approach [PDF]

open access: yes, 2010
The current study tested the assumption that floristic and functional diversity patterns are negatively related to soil nitrogen content. We analyzed 20 plots with soil N-contents ranging from 0.63% to 1.06% in a deciduous forest near Munich (Germany ...
