Models to estimate the above and below ground carbon stocks from a subtropical scrub forest of Pakistan

Global Ecology and Conservation, 2021
Despite an increased number of studies on carbon stock estimates from tropical and temperate forests, little information is available for subtropical forests, although they constitute a significant proportion of global forest cover. In this present study,

Plasticity and ontogenetic drift of biomass allocation in response to above- and below-ground resource availabilities in perennial herbs: a case study of Alternanthera philoxeroides [PDF]

, 2007
Changes in plant biomass allocation in response to varying resource availabilities may result from ontogenetic drift caused by allometric growth (i.e., apparent plasticity), a true adjustment of ontogenetic trajectories (true plasticity) or both (complex

The effect of elevated air CO2 concentration on dendrometric parameters and biomass of European beech and Norway spruce in their monocultures and intermixtures

Central European Forestry Journal
An increased CO2 concentration should have a positive effect on tree growth, but in different species mixtures, due to mutual interaction between species, this effect may be insignificant or even negative. Therefore, our research focused on the influence

The above- and below-ground biomass of alpine meadow on eastern margin of the Tibetan Plateau and their relationships with abiotic and biotic factors

Global Ecology and Conservation, 2023
Our knowledge of grassland biomass and its relationships with abiotic and biotic factors on eastern margin of the Tibetan Plateau is extremely limited. Here, we measured above-ground biomass (AGB), below-ground biomass (BGB) and root/shoot ratio (R/S) of

Contrasting effects of nutrient enrichment on below‐ground biomass in coastal wetlands [PDF]

Journal of Ecology, 2015
Summary Anthropogenically enhanced nutrient availability is often cited among the most important drivers of altered ecosystem function and loss of services world‐wide. Although the above‐ground consequences of nutrient enrichment on plant growth patterns are numerous and well documented, below‐ground impacts are less clear but nonetheless critical ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Age-related equations for above- and below-ground biomass of a Eucalyptus hybrid in Congo [PDF]

, 2005
A complete set of equations for below - and above-ground biomass of a natural Eucalyptus hybrid in Congo was constructed. Heteroscedasticity of data was taken into account by fitting weighted non-linear regressions using maximum likelihood estimates ...

Above-ground and Below-ground Biomass situation of Milke-Jaljale Rangeland at Different Altitudinal Gradient [PDF]

Our Nature, 1970
Rangeland conservation has been increasingly interested for carbon reduction and mitigation of climate change, because of carbon storage. Thus, biomass of the rangeland remains pivotal regarding carbon sequestration on rangeland. Present study was conducted in high altitude rangeland at Jaljale (4000 m), Gorujure (3500 m) and Milke (3000 m) on ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.
