Modeling Uncertainties in Spatiotemporal Dynamic of Vegetation Above- and Belowground Production on the Tibetan Plateau

Ecosystem Health and Sustainability
Net primary production (NPP), comprising both aboveground (ANPP) and belowground (BNPP) components, serves as a critical indicator for evaluating terrestrial ecosystem responses to climate change.

Yield gap and the shares of climate and crop management in yield and yield variability of staple crops in West Africa. [O-3330b-01] [PDF]

, 2015
" Yield gap " (Yg) is a key concept of agricultural science for identifying the room for improvement of yields through better management of the agroecosystem. in rainfed agriculture Yg is the difference between actual yield (Ya) and the theoretical water

Soil-surface CO2 flux and growth in a boreal Norway spruce stand [PDF]

, 2001
Global warming is predicted to affect the carbon balance of forests. A change in the carbon balance would give a positive or negative feedback to the greenhouse effect, which would affect global warming.

Charge-dependence of the $\pi NN$ coupling constant and charge-dependence of the NN interaction

, 1999
The recent determination of the charged $\pi NN$ coupling constant, $g_{\pi^\pm}$, by the Uppsala Neutron Research Group implies that there may be considerable charge-splitting of the pion coupling constant.

Interactions among resource partitioning, sampling effect, and facilitation on the biodiversity effect: A modeling approach [PDF]

, 2013
Resource partitioning, facilitation, and sampling effect are the three mechanisms behind the biodiversity effect, which is depicted usually as the effect of plant-species richness on aboveground net primary production.

Phosphorus effects on global grassland productivity and plant diversity: A meta-analysis

Global Ecology and Conservation
Phosphorus (P) addition can affect ecosystem functions. It plays an important role in the productivity and nutrient cycling of grassland ecosystems. However, the effects of P addition on plant community diversity and productivity remain controversial. We

Effects of rising atmospheric CO2, climate change, and nitrogen deposition on aboveground net primary production in a temperate forest

Environmental Research Letters, 2019
Temperate forests regrowing from historical land use and land cover change in the eastern US serve as carbon (C) sinks. Environmental drivers have been significantly altered (e.g.
