Using the red-imported fire ant to study invasive species removal and reinvasion
(2024-02-02)
Invasive species are a major driver of native species declines, frequently resulting in a reduction of ecosystem function. Though control of invasive species is often beneficial, it can create other ecological issues. ...
Effect of nitrogen deposition on China’s terrestrial carbon uptake in the context of multifactor environmental changes
(2023-09-20)
The amount of atmospheric nitrogen (N) deposited on the land surface has
increased globally and by nearly five times in China from 1901 to 2005. Little is known about
how elevated reactive N input has affected the carbon ...
Responses of global terrestrial evapotranspiration to climate change and increasing atmospheric CO2 in the 21st century
(2023-06-17)
Quantifying the spatial and temporal patterns of the water lost to the atmosphere through land surface evapotranspiration (ET) is essential for understanding the global hydrological cycle, but remains much uncertain. In ...
Building Consensus for Ambitious Climate Action Through the World Climate Simulation
(2023-01-14)
Sociopolitical values are an important driver of climate change beliefs, attitudes, and policy preferences. People with individualist-hierarchical values favor individual freedom, competition, and clearly defined social ...
Contribution of increasing CO2 and climate change to the carbon cycle in China's ecosystems
(2022-12-06)
Atmospheric CO2 and China's climate have changed greatly during 1961-2000. The influence of increased CO2 and changing climate on the carbon cycle of the terrestrial ecosystems in China is still unclear. In this article ...
Effects of tropospheric ozone pollution on net primary productivity and carbon storage in terrestrial ecosystems of China
(2022-12-05)
We investigated the potential effects of elevated ozone (O-3) along with climate variability, increasing CO2, and land use change on net primary productivity (NPP) and carbon storage in China's terrestrial ecosystems for ...
Evaluating water stress controls on primary production in biogeochemical and remote sensing based models
(2022-12-02)
Water stress is one of the most important limiting factors controlling terrestrial primary production, and the performance of a primary production model is largely determined by its capacity to capture environmental water ...
Heavy Precipitation Impacts on Nitrogen Loading to the Gulf of Mexico in the 21st Century: Model Projections Under Future Climate Scenarios
(2022-12-02)
While spatial heterogeneity of riverine nitrogen (N) loading is predominantly driven by the magnitude of basin-wide anthropogenic N input, the temporal dynamics of N loading are closely related to the amount and timing of ...
Integrating a process-based ecosystem model with Landsat imagery to assess impacts of forest disturbance on terrestrial carbon dynamics: Case studies in Alabama and Mississippi
(2022-12-02)
Forest ecosystems in the southern United States are dramatically altered by three major disturbances: timber harvesting, hurricane, and permanent land conversion. Understanding and quantifying effects of disturbance on ...
Satellite Observations of the Recovery of Forests and Grasslands in Western China
(2022-12-02)
The Grain for Green Program (GGP), which combats and reverses the landscape-scale habitat degradation by converting agricultural lands to forests and grasslands, was launched in 1999 in western China. An assessment of the ...
Spatial and temporal patterns of nitrogen deposition in China: Synthesis of observational data
(2022-11-07)
[1] Anthropogenic nitrous pollutant emissions in China significantly increased during the last decades, which contributed to the accelerated nitrogen ( N) deposition. In order to characterize spatial pattern of nitrogen ...
Net exchanges of CO2, CH4, and N2O between China's terrestrial ecosystems and the atmosphere and their contributions to global climate warming
(2022-10-25)
China's terrestrial ecosystems have been recognized as an atmospheric CO2 sink; however, it is uncertain whether this sink can alleviate global warming given the fluxes of CH4 and N2O. In this study, we used a process-based ...
Global Pyrogenic Carbon Production During Recent Decades Has Created the Potential for a Large, Long-Term Sink of Atmospheric CO2
(2022-10-20)
Fires play an important role in the terrestrial biosphere carbon cycle, not only through direct carbon release but also contributing to a potential long-term storage as pyrogenic carbon (PyC). PyC is formed through fires, ...
The thermal conductivity of Earth's lower mantle
(2022-09-16)
We assess the thermal conductivity of the Earth’s lower mantle anchored on our first-principles
calculations of lattice thermal conductivity of MgSiO3 perovskite. Our calculations agree with measurements
of iron-free ...
Incubation Conditions Are More Important in Determining Early Thermoregulatory Ability than Posthatch Resource Conditions in a Precocial Bird
(2022-09-16)
Recent research in birds suggests that investing in incubation
is one mechanism by which parents can enhance the phenotype
of their offspring. Posthatch environmental conditions can also
shape an individual’s phenotype, ...
Increasing Mississippi river discharge throughout the 21st century influenced by changes in climate, land use, and atmospheric CO2
(2022-09-15)
Previous studies have demonstrated that changes in temperature and precipitation (hereafter
climate change) would influence river discharge, but the relative importance of climate change, land use,
and elevated atmospheric ...
Epigenetics in Ecology, Evolution, and Conservation
(2022-08-26)
Epigenetic variation is often characterized by modifications to DNA that do not alter the underlying nucleotide sequence, but can influence behavior, morphology, and physiological phenotypes by affecting gene expression ...
Improving Representation of Crop Growth and Yield in the Dynamic Land Ecosystem Model and Its Application to China
(2022-07-29)
To accurately assess the roles of agriculture in securing food security and maintaining environmental sustainability, it is essential to improve the representation of crop growth, development, and yield formation in global ...
BODY-MASS, STRUCTURAL SIZE, AND LIFE-HISTORY PATTERNS OF THE COLUMBIAN GROUND-SQUIRREL
(2022-07-29)
Columbian ground squirrels (Spermophilus columbianus) exhibit an elevational cline in several life-history traits and in body mass. Body mass is a trait that might interact with the elevational changes in life histories, ...
