Comparison of Microbial Communities in the Sediments and Water Columns of Frozen Cryoconite Holes in the McMurdo Dry Valleys, Antarctica

Frontiers in Microbiology, 2019
Although cryoconite holes, sediment-filled melt holes on glacier surfaces, appear small and homogenous, their microbial inhabitants may be spatially partitioned. This partitioning could be particularly important for maintaining biodiversity in holes that

Nitrogen balance and gap of a high yield tropical soybean crop under irrigation

Frontiers in Plant Science, 2023
Nitrogen (N) is the most extracted and exported element by the soybean crop. In high yield tropical environments with irrigation, little is known about N accumulation in different soybean plant organs as well as the N balance. The objective of this study

Atmospheric tar balls: Particles from biomass and biofuel burning [PDF]

, 2004
"Tar balls'' are amorphous, carbonaceous spherules that occur in the tropospheric aerosol as a result of biomass and biofuel burning. They form a distinct group of particles with diameters typically between 30 and 500 nm and readily identifiable with ...

Fruiting, Morphology, and Architecture of ‘Arbequina’ and ‘Calatina’ Olive Branches

Horticulturae, 2022
Two different olive cultivars grown under a high-density hedgerow system were studied to compare their fruiting and branch architecture features and to determine the possibility to use ‘Calatina’ olive trees for intensive plantings, as a local ...

Minor and Trace Element Emissions from Post-Combustion CO2 Capture from Coal: Experimental and Equilibrium Calculations [PDF]

, 2014
Elemental partitioning, including gaseous elemental emissions from pilot scale (25 kWth), post combustion CO2 capture using a Ca-based sorbent, have been investigated for naturally occurring elemental impurities found in limestone, that have the ...

Reexamination of a canonical model for plant organ biomass partitioning [PDF]

American Journal of Botany, 2003
A previously proposed “canonical” model for the scaling relations among leaf, stem, and root biomass (ML, MS, and MR, respectively) asserts that the proportional relations ML ∝ MS3/4 ∝ MR3/4 and MS ∝ MR hold across seed plant species. This model is scrutinized by determining whether the scaling relations between ML, MS, and MR vs.

Genotypic differences in soybean (Glycine max L.) in yield response to phosphorus fertilizer are associated with difference in biomass and phosphorus content

Journal of Agriculture and Food Research
The soybean seed yield response to phosphorus (P) fertilizer has significantly increased during soybean breeding but the underlying mechanisms remain elusive. In this study, we used two soybean cultivars with high (Andou 8 (AD8)) and low (Qiandou 5 (QD5))

Partitioning Of Carbohydrates And Biomass Of Needles In Scots Pine Canopy

Zeitschrift für Naturforschung C, 2002
The study was aimed at the quantitative evaluation of the temporal and spatial partitioning of non-structural carbohydrates and needle biomass in a canopy of Scots pine (Pinus sylvestris L.) growing in a Myrtillus site type forest stand (predominant in Estonia).

Evaluation of Rice Straw Yield, Fibre Composition and Collection Under Mediterranean Conditions

Acta Technologica Agriculturae, 2019
Rice straw remains almost unutilised in the majority of cases and is usually burned. Data on rice residue production under European conditions are extremely limited.
