Space-time quantification of aboveground net primary productivity service supply capacity in high Andean bofedales using remote sensors [PDF]

Journal of Water and Land Development, 2023
The aboveground net primary productivity ( ANPP) of bofedales is one of the most important indicators for the provision of ecosystem services in the high Andean areas. In the case of bofedales, the evaluation of the ANPP supply capacity as a service on a

Growth dynamics and productivity of pure and mixed Castanea sativa Mill. and Pseudotsuga menziesii (Mirb.) Franco plantations in northern Portugal

iForest - Biogeosciences and Forestry, 2014
Since the late 1980’s the productivity of monocultures versus mixed-species forests has been the object of special interest and study by forest managers and ecologists.

Estimating Aboveground Net Primary Production in Grasslands: A Comparison of Nondestructive Methods [PDF]

Rangeland Ecology & Management, 2011
Abstract Aboveground net primary production (ANPP) is an important ecosystem property that is affected by environmental variability. ANPP in grasslands is typically measured by clipping peak live plant material. However, this method is time intensive (and therefore expensive), making it difficult to capture spatial and temporal variability ...

Community level offset of rain use- and transpiration efficiency for a heavily grazed ecosystem in inner Mongolia grassland.

PLoS ONE, 2013
Water use efficiency (WUE) is a key indicator to assess ecosystem adaptation to water stress. Rain use efficiency (RUE) is usually used as a proxy for WUE due to lack of transpiration data.

Precipitation-use efficiency may explain net primary productivity allocation under different precipitation conditions across global grassland ecosystems

Global Ecology and Conservation, 2019
Conclusions made regarding plant biomass allocation, trade-off patterns and aboveground/belowground biomass without considering the existence of perennials in grassland ecosystems are under fierce debate.

Early spring, severe frost events, and drought induce rapid carbon loss in high elevation meadows. [PDF]

PLoS ONE, 2014
By the end of the 20th century, the onset of spring in the Sierra Nevada mountain range of California has been occurring on average three weeks earlier than historic records.

Carbon stocks in managed conifer forests in northern Ontario, Canada

Silva Fennica, 2010
Carbon pools and net primary productivity (aboveground) were measured in managed stands of jack pine (Pinus banksiana Lamb.) and black spruce (Picea mariana [Mill.] B.S.P.), ranging in age from 10 to 53 years, in the Lake Nipigon area of northern ...
