Do contaminants originating from state-of-the-art treated wastewater impact the ecological quality of surface waters? [PDF]

open access: yes, 2013
Since the 1980s, advances in wastewater treatment technology have led to considerably improved surface water quality in the urban areas of many high income countries.

Fungal Traits Important for Soil Aggregation [PDF]

open access: yes, 2020
Soil structure, the complex arrangement of soil into aggregates and pore spaces, is a key feature of soils and soil biota. Among them, filamentous saprobic fungi have well-documented effects on soil aggregation. However, it is unclear what properties, or

Structure and character analysis of cotton response regulator genes family reveals that GhRR7 responses to draught stress

open access: yesBiological Research, 2022
Background Cytokinin signal transduction is mediated by a two-component system (TCS). Two-component systems are utilized in plant responses to hormones as well as to biotic and abiotic environmental stimuli. In plants, response regulatory genes (RRs) are

Species diversity pattern and its drivers of the understory herbaceous plants in a Chinese subtropical forest

open access: yesFrontiers in Ecology and Evolution, 2023
Understory herbaceous plants are an important component of forest ecosystems, playing important roles in species diversity and forest dynamics in forests.

The role of mangrove fine root production and decomposition on soil organic carbon component ratios

open access: yesEcological Indicators, 2021
Mangrove fine roots are an important contributor to soil organic matter (SOC), yet how their production and decomposition affect SOC accumulation across the sea-land gradient is still elusive.

The Evolution of Multicomponent Systems at High Pressures: VI. The Thermodynamic Stability of the Hydrogen-Carbon System: The Genesis of Hydrocarbons and the Origin of Petroleum

open access: yes, 2002
The spontaneous genesis of hydrocarbons which comprise natural petroleum have been analyzed by chemical thermodynamic stability theory. The constraints imposed upon chemical evolution by the second law of thermodynamics are briefly reviewed; and the ...

Nitrification amplifies the decreasing trends of atmospheric oxygen and implies a larger land carbon uptake [PDF]

open access: yes, 2007
[1] Atmospheric O-2 trend measurements are used to partition global oceanic and land biotic carbon sinks on a multiannual basis. The underlying principle is that a terrestrial uptake or release of CO2 is accompanied by an opposite flux of O-2.

Tree defence and bark beetles in a drying world: carbon partitioning, functioning and modelling. [PDF]

open access: yes, 2020
Drought has promoted large-scale, insect-induced tree mortality in recent years, with severe consequences for ecosystem function, atmospheric processes, sustainable resources and global biogeochemical cycles.

Partitioning of net CO2 exchanges at the city-atmosphere interface into biotic and abiotic components

open access: yesMethodsX, 2021
Eddy covariance (EC) method has been used to measure CO2 fluxes over various ecosystems. Recently, the EC method has been also deployed in urban areas to measure CO2 fluxes. Urban carbon cycle is complex because of the additional anthropogenic processes unlike natural ecosystems but the EC method only measures the net sum of all CO2 sources and sink ...
