Current forest carbon fixation fuels stream CO2 emissions [PDF]

open access: yesNature Communications, 2019
AbstractStream CO2 emissions contribute significantly to atmospheric climate forcing. While there are strong indications that groundwater inputs sustain these emissions, the specific biogeochemical pathways and timescales involved in this lateral CO2 export are still obscure.

On the key role of droughts in the dynamics of summer fires in Mediterranean Europe [PDF]

open access: yes, 2017
Summer fires frequently rage across Mediterranean Europe, often intensified by high temperatures and droughts. According to the state-of-the-art regional fire risk projections, in forthcoming decades climate effects are expected to become stronger and ...

METHODOLOGICAL APPROACHES TO MAPPING FOREST FUELS

open access: yesFOREST SCIENCE ISSUES, 2023
Spatial data on the vertical structure and forest fuel loads are a very importance for reliable estimates of direct fire carbon emissions. Main purpose of our paper is to demonstrate methodological approaches to mapping pre-fire forest fuels, which sets of multidimensional regression models and thematic satellite products of forest stand ...

Plant functional type and peat properties determine elemental transfer in boreal mire vegetation

open access: yesHeliyon
Uptake of elements into plants is an integral part of many environmental impact assessments. Typically, the plant uptake is determined using an empirical soil-to-plant transfer factor (CR). The elemental concentrations in plants are expected to vary with

Microwave attenuation in forest fuel flames [PDF]

open access: yesCombustion and Flame, 2008
The flames of forest fuels form a weakly ionized gas. Assuming a Maxwellian velocity distribution of flame particle and collision frequencies much higher than plasma frequencies, the propagation of microwaves through forest fuel flames is predicted to have attenuation and phase shift.

Short and long-term carbon balance of bioenergy electricity production fueled by forest treatments [PDF]

open access: yes, 2014
Background: Forests store large amounts of carbon in forest biomass, and this carbon can be released to the atmosphere following forest disturbance or management.

Oxidizing and Nano-dispersing the Natural Silk Fibers

open access: yesNanoscale Research Letters, 2019
Natural Bombyx mori silk (BS) and Antheraea pernyi silk (AS) were oxidized in sodium hypochlorite (NaClO) solutions. Thereafter, individual silk nanofibers (SNs) were achieved after sonicating the oxidized silk slurries, where the diameters of the ...

Institutions, sustainable land use and consumer welfare: the case of forest and grazing lands in northern Ethiopia [PDF]

open access: yes, 2011
Land is an essential factor of production. Institutions that govern its efficient use determine the sustainability of this essential resource. In Ethiopia all land is publicly owned.

Effect of Microbial Degradation Treatments on Lignocellulose, Cellulose, and Water-Holding Capacity of Four Typical Forest Fuels from Northeast China

open access: yesFire
Since forest fuel decomposes slowly and increases the risk of forest fires by accumulating over the years, forest fuel management to accelerate the decomposition process is essential to prevent forest fires and protect forest resources. In this study, we
