Quantifying Dynamics in Tropical Peat Swamp Forest Biomass with Multi- Temporal LiDAR Datasets [PDF]

, 2013
Tropical peat swamp forests in Indonesia store huge amounts of carbon and are responsible for enormous carbon emissions every year due to forest degradation and deforestation.

Model-based inference for biomass estimation in a LiDAR sample survey in Hedmark County, Norway [PDF]

, 2011
In forest inventories, regression models are often applied to predict quantities such as biomass at the level of sampling units. In this paper, we propose a model-based inference framework for combining sampling and model errors in the variance ...

Below-ground physiological processes enhancing phosphorus acquisition in plants

, 2021
Phosphorus (P) is an essential element for crop growth and development. In acid soils, inorganic P (Pi) is immobilised with Fe3+ and Al3+, whereas in calcareous soils, it is fixed with Ca2+. Therefore, P nutrition is not constrained by soil P content per

Grazing exclusion reduces below‐ground biomass of temperate subhumid grasslands of South America: A meta‐analysis and a database

, 2023
There are several plant below-ground biomass databases for grasslands, but the contribution from the southern hemisphere is minimal. Particularly, no study has compiled the published values of plant below-ground biomass for the temperate subhumid ...

Quantifying Carbon Sequestration in Woody Trees of Makurdi Zoological Garden, Benue State, Nigeria: A Non-Destructive Approach

UMYU Scientifica Journal
Carbon emissions and reflection are some of the most significant and urgent environmental problems in the world today due to climate change, and because of their ability to sequester Carbon, trees significantly reduce the amount of carbon dioxide in the

Combining airborne laser scanning and Landsat data for statistical modeling of soil carbon and tree biomass in Tanzanian Miombo woodlands

Carbon Balance and Management, 2017
Background Soil carbon and biomass depletion can be used to identify and quantify degraded soils, and by using remote sensing, there is potential to map soil conditions over large areas. Landsat 8 Operational Land Imager satellite data and airborne laser

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 ...

Implications of contrasted above- and below-ground biomass responses in a diversity experiment with trees

, 2020
While tree diversity has been proven to enhance above‐ground forest biomass in many instances, the effect on below‐ground biomass has often been neutral, or even negative.

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,

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
