Contrasting and interacting changes in simulated spring and summer carbon cycle extremes in European ecosystems

Environmental Research Letters, 2017
Climate extremes have the potential to cause extreme responses of terrestrial ecosystem functioning. However, it is neither straightforward to quantify and predict extreme ecosystem responses, nor to attribute these responses to specific climate drivers.

MODERATE SEVERITY DISTURBANCE HAS SIMILAR EFFECTS ON THE PRODUCTION OF THREE FORESTS NESTED WITHIN THE UPPER GREAT LAKES LANDSCAPE [PDF]

, 2017
Moderate severity disturbances, which only kill a subset of canopy trees (e.g., via insects, pathogens, and windthrow), are increasingly widespread, and can alter forest structure and production.

Assessing Agricultural Green Total Factor Productivity in Latin America

Agribusiness, EarlyView.
ABSTRACT The agricultural sector in Latin America plays a vital role in ensuring food security while impacting the environment. However, there remains a lack of analysis regarding the inputs responsible for pollution within its sub‐technologies. Hence, this article aims to assess agricultural green total factor productivity (TFP) through a novel ...

Effects of Nitrogen Addition on the Drought Susceptibility of the Leymus chinensis Meadow Ecosystem Vary with Drought Duration

Frontiers in Plant Science, 2018
It is not clear yet how extreme drought and nitrogen (N) deposition influence grassland ecosystem functions when they are considered together, especially in complex field conditions.

Staging an Experience of Cultural Heritage Preservation: Consumers' Willingness to Pay for Heirloom Rice in the Philippines

Agribusiness, EarlyView.
ABSTRACT The Cordillera Administrative Region in the Philippines is home to terraced rice embedded in centuries of cultural heritage. However, weak market incentives threaten sustained production, jeopardizing indigenous communities' cultural heritage and the in situ biodiversity of rice genetic resources.

Analyzing the causes and spatial pattern of the European 2003 carbon flux anomaly in Europe using seven models [PDF]

, 2007
International audienceGlobally, the year 2003 is associated with one of the largest atmospheric CO2 rises on record. In the same year, Europe experienced an anomalously strong flux of CO2 from the land to the atmosphere associated with an exceptionally ...

Modeling of the net ecosystem exchange, gross primary production, and ecosystem respiration for peatland ecosystems of Western Siberia

IOP Conference Series: Earth and Environmental Science, 2018
Observed and simulated carbon dioxide fluxes in oligotrophic peatlands of West Siberia are discussed. Net ecosystem exchange, gross primary production and ecosystem respiration were measured at ridge-hollow complex at South Taiga zone (Bakchar bog – field sataion “Vasjuganie”) and Middle Taiga zone (field station “Mukhrino”). The model of net ecosystem

How Competitive Is Myanmar's Rice Sector? A Comparison of Production Costs and Efficiency

Agribusiness, EarlyView.
ABSTRACT This paper analyzes the cost competitiveness of rice production in Myanmar by examining production costs, cost efficiency, and the potential effect of improving cost efficiency on the country's global competitiveness. To achieve this, we conduct a comparative analysis of production costs among major rice‐producing countries and estimate the ...

Analysis of the spatiotemporal dynamics of grassland carbon sinks in Xinjiang via the improved CASA model

Ecological Indicators
Accurate assessment of grassland carbon sinks provides scientific data for quantifying the global carbon balance. Currently, methods for precisely calculating NPP (net primary productivity) and NEP (net ecosystem productivity) in arid grasslands are ...

Predicting Ecosystem Net Primary Productivity by Percolation Theory and Optimality Principle

Water Resources Research
The basic partitioning of precipitation P into evapotranspiration ET and run‐off Q is known as the “central problem of hydrology.” ET depends primarily on precipitation, P, and potential evapotranspiration, PET, which are connected by the biological ...
