Asymmetric warming significantly affects net primary production, but not ecosystem carbon balances of forest and grassland ecosystems in northern China [PDF]

open access: yes, 2015
We combine the process-based ecosystem model (Biome-BGC) with climate change-scenarios based on both RegCM3 model outputs and historic observed trends to quantify differential effects of symmetric and asymmetric warming on ecosystem net primary ...

The allocation of ecosystem net primary productivity in tropical forests [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2011
The allocation of the net primary productivity (NPP) of an ecosystem between canopy, woody tissue and fine roots is an important descriptor of the functioning of that ecosystem, and an important feature to correctly represent in terrestrial ecosystem models.

Understanding drivers of aquatic ecosystem metabolism in freshwater subtropical ridge and slough wetlands

open access: yesEcosphere, 2021
How climate and habitat drive variation in aquatic metabolism in wetlands remains uncertain. To quantify differences in seasonal aquatic metabolism among wetlands, we estimated aquatic ecosystem metabolism (gross primary productivity, GPP; ecosystem ...

Understanding the effect of disturbance from selective felling on the carbon dynamics of a managed woodland by combining observations with model predictions [PDF]

open access: yes, 2017
The response of forests and terrestrial ecosystems to disturbance is an important process in the global carbon cycle in the context of a changing climate.

Improvement of water yield and net primary productivity ecosystem services in the Loess Plateau of China since the “Grain for Green” project

open access: yesEcological Indicators, 2023
The Loess Plateau of China is one of the regions with the most serious soil erosion globally. The ambitious “Grain for Green” project was there implemented to restore degraded ecosystems, profoundly changing the water yield and carbon sequestration ...

Net ecosystem productivity and its uncertainty in a diverse boreal peatland [PDF]

open access: yes, 1999
Net ecosystem exchange (NEE) of CO2 was measured in four peatlands along plant community, hydrologic, and water chemistry gradients from bog to rich fen in a diverse peatland complex near Thompson, Manitoba, as part of the Boreal Ecosystem-Atmosphere ...

Upside-down fluxes Down Under: CO2 net sink in winter and net source in summer in a temperate evergreen broadleaf forest [PDF]

open access: yes, 2018
Predicting the seasonal dynamics of ecosystem carbon fluxes is challenging in broadleaved evergreen forests because of their moderate climates and subtle changes in canopy phenology.

NET ECOSYSTEM PRODUCTIVITY STUDIES IN MANGROVE FORESTS

open access: yesReviews in Agricultural Science, 2013
The carbon dynamics of forest ecosystems are particularly significant to the phenomenon of global warming. Mangrove forests situated between aquatic and terrestrial ecosystems show unique patterns of biomass allocation and carbon dynamics, as they are subjected to daily tidal inundations and a mixture of seawater and fresh water.

Water use efficiency of China\u27s terrestrial ecosystems and responses to drought [PDF]

open access: yes, 2015
Water use efficiency (WUE) measures the trade-off between carbon gain and water loss of terrestrial ecosystems, and better understanding its dynamics and controlling factors is essential for predicting ecosystem responses to climate change.

Influence of Spring and Autumn Phenological Transitions on Forest Ecosystem Productivity [PDF]

open access: yes, 2010
We use eddy covariance measurements of net ecosystem productivity (NEP) from 21 FLUXNET sites (153 site-years of data) to investigate relationships between phenology and productivity (in terms of both NEP and gross ecosystem photosynthesis, GEP) in ...
