A meta-analysis of crop response patterns to nitrogen limitation for improved model representation [PDF]

, 2019
The representation of carbon-nitrogen (N) interactions in global models of the natural or managed land surface remains an important knowledge gap. To improve global process-based models we require a better understanding of how N limitation affects ...

Dissimilar roles of aerosols, nitrogen deposition and ozone on the terrestrial carbon sink in China during 2010–2020 [PDF]

Atmospheric Chemistry and Physics
China's Clean Air Action (CAA) plan implemented since 2013 has significantly altered atmospheric composition, and yet its impact on the terrestrial carbon sink remains unclear.

Law and Policy Dimensions of Ocean Governance

Oceans, 2019
Human populations have relied on the oceans for centuries for food supply, transportation, security, oil and gas resources, and many other reasons. The growing prospects of the oceans, such as access to marine genetic resources and seabed minerals, to ...

A Novel Approach Using Multiple Fluorescence Signals and Storm Event Clustering to Identify Riverine Dissolved Organic Matter Source Activation Pathways

Water Resources Research
Despite the potential of multipeak in situ fluorescence to provide better insight into solute transport pathways, most high frequency studies have focused on a single fluorescence peak (e.g., humic‐like fluorescence [HLF]).

Effective data routing using mobile sinks in disjoint mobile wireless sensor networks

Periodicals of Engineering and Natural Sciences (PEN), 2019
In Mobile WSNs (MWSNs) , disjoint clusters could be naturally formed in an unpredictable way that possess the nature of highly dynamic connected and disconnected schema.

A variable North Atlantic sink for anthropogenic CO2: modelling observed change [PDF]

, 2018
To determine the maximum carbon dioxide (CO2) emissions consistent with a given global warming threshold, the scientific community must robustly quantify what proportion of human emitted CO2 will be taken up by the terrestrial and marine carbon ...

Mapping the “Supply–Demand–Flow” of Ecosystem Services for Ecosystem Management in China

Advanced Science, EarlyView.
This study develops a “supply–demand–flow” framework clarifies how ecosystem services move between regions by distinguishing potential and actual supply and demand. Using integrated biophysical–socioeconomic modeling, nine services in China were mapped.

Detecting Shifts of Monsoon Precipitation Patterns and a Large Increase in Soil Erosion Potential During 1979–2020 in Nepal

Remote Sensing
Nepal is highly vulnerable to severe soil erosion driven by monsoonal rainfall and rugged terrains. Limitations in ground observation networks have hindered comprehensive, high-resolution national assessment of precipitation and rainfall-runoff erosivity

A NOVEL RESOURCE CONSTRAINT SECURE(RCS) ROUTING PROTOCOL FOR WIRELESS SENSOR NETWORK [PDF]

Journal of Engineering Science and Technology, 2017
Geographic routing protocols are the most preferred routing protocols for Wireless Sensor Networks (WSN) since they rely on geographic position information. Hence we propose geography based Resource Constraint Secure routing (RCS) protocol.

Eco‐Geography Reverses Dominant AMR Reservoirs in Klebsiella pneumoniae: Integron‐Rich Mobilomes and Cross‐Niche Connectivity

Advanced Science, EarlyView.
Dominant antimicrobial resistance reservoirs in Klebsiella pneumoniae vary across eco‐geographic settings rather than following a universal pattern. Integrated One Health and global genomic analyses show that lineage structure, integron load, and cross‐niche connectivity shape whether AMR burden accumulates primarily in human or nonhuman compartments ...
