Remote Sensing, 2018 Monitoring of aboveground net primary production (ANPP) is critical for effective management of rangeland ecosystems but is problematic due to the vast extent of rangelands globally, and the high costs of ground-based measurements.

Ecosystem resilience despite large-scale altered hydroclimatic conditions [PDF]
, 2013 Climate change is predicted to increase both drought frequency and duration, and when coupled with substantial warming, will establish a new hydroclimatological model for many regions.

Ecological Indicators, 2014 Abstract Aboveground net primary production (ANPP) is a key ecosystem characteristic and of fundamental importance for essentially all aspects of matter and energy fluxes in terrestrial ecosystems. Various methods for estimating ANPP are available and despite partial consensus on ‘best practice methods’ important methodological issues remain ...

‘Gold, guns & goons’: the complexity of electoral irregularities in Nigeria, 1999-2007 [PDF]
, 2010 Electoral irregularities have become an irritant but inseparable aspect of democratic development in several countries of the world. From the US Florida electoral crisis of 2000 to the Orange Revolution in Ukraine in 2004/2005, which was staged to ...

No effect of seed source on multiple aspects of ecosystem functioning during ecological restoration: cultivars compared to local ecotypes of dominant grasses [PDF]
, 2013 Genetic principles underlie recommendations to use local seed, but a paucity of information exists on the genetic distinction and ecological consequences of using different seed sources in restorations.

Successional change in species composition alters climate sensitivity of grassland productivity. [PDF]
, 2018 Succession theory predicts altered sensitivity of ecosystem functions to disturbance (i.e., climate change) due to the temporal shift in plant community composition.

Radiation use and understory aboveground net primary production in a temperate dryland
Ecosphere, Volume 16, Issue 12, December 2025.Abstract We investigated the spatial and temporal variability of herbaceous radiation use efficiency (RUEh$$ {\mathrm{RUE}}_h $$) and herbaceous aboveground net primary production (ANPPh$$ {\mathrm{ANPP}}_h $$) of big sagebrush ecosystems in Wyoming's Upper Green River Basin.

Microbial functional diversity covaries with permafrost thaw-induced environmental heterogeneity in tundra soil. [PDF]
, 2017 Permafrost soil in high latitude tundra is one of the largest terrestrial carbon (C) stocks and is highly sensitive to climate warming. Understanding microbial responses to warming-induced environmental changes is critical to evaluating their influences ...

Heatwaves leave a legacy on a dominant understory grass in longleaf pine savanna
Ecosphere, Volume 16, Issue 12, December 2025.Abstract The frequency and intensity of extreme climatic events such as heatwaves are predicted to increase under continued climate change and rising atmospheric CO2. Degraded and fragmented ecosystems are at particular risk of being greatly impacted by such extreme events.
