Elevated CO₂ does not increase eucalypt forest productivity on a low-phosphorus soil [PDF]

, 2017
Rising atmospheric CO2 stimulates photosynthesis and productivity of forests, offsetting CO2 emissions. Elevated CO2 experiments in temperate planted forests yielded ~23% increases in productivity over the initial years.

Research Advances in Net Primary Productivity of Terrestrial Ecosystem

Journal of Geoscience and Environment Protection, 2020
The net primary productivity of vegetation reflects the total amount of carbon fixed by plants through photosynthesis each year. The study of vegetation net primary productivity is one of the core contents of global change and terrestrial ecosystems. This article reviews the current research status of net primary productivity of terrestrial vegetation,

Coinciding spring and autumn frosts have a limited impact on carbon fluxes in a grassland ecosystem

Nature Communications
Frosts, increasingly prevalent due to climate warming, can offset the carbon storage benefits of an extended growing season, potentially exacerbating climate warming.

Balancing Electrons to Break the Activity‐Selectivity Trade‐Off in H2O2 Electrosynthesis

Advanced Functional Materials, EarlyView.
Carrier‐concentration balancing in CuS is achieved by coupling cobalt dopants with cobalt vacancies, converting CuS from p‐ to n‐type to accelerate 2e− ORR while withdrawing excess carriers to optimize *OOH binding for H2O2 desorption. The catalyst reaches 8.14 mol g−1 h−1 with >84% selectivity in 1.0 M KOH and drives robust electro‐Fenton dye ...

Uncovering the ecosystem service legacies of wetland loss using high‐resolution models

Ecosphere, 2019
Ecosystem services provided by contemporary landscapes are different from those of the past, and this difference is influenced by the legacies of policies that incentivized wetland drainage without considering the impact on ecosystem services ...

Scaling net ecosystem production and net biome production over a heterogeneous region in the western United States [PDF]

Biogeosciences, 2007
Abstract. Bottom-up scaling of net ecosystem production (NEP) and net biome production (NBP) was used to generate a carbon budget for a large heterogeneous region (the state of Oregon, 2.5×105 km2) in the western United States. Landsat resolution (30 m) remote sensing provided the basis for mapping land cover and disturbance history, thus allowing us ...

Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Rates of sustainable forest harvest depend on rotation length and weathering of soil minerals [PDF]

, 2014
Removals of forest biomass in the northeastern US may intensify over the coming decades due to increased demand for renewable energy. For forests to regenerate successfully following intensified harvests, the nutrients removed from the ecosystem in the ...

Climate controls over the net carbon uptake period and amplitude of net ecosystem production in temperate and boreal ecosystems [PDF]

Agricultural and Forest Meteorology, 2017
The seasonal and interannual variability of the terrestrial carbon cycle is regulated by the interactions of climate and ecosystem function. However, the key factors and processes determining the interannual variability of net ecosystem productivity (NEP) in different biomes are far from clear.
