biomass: an r package for estimating above‐ground biomass and its uncertainty in tropical forests [PDF]

Methods in Ecology and Evolution, 2017
Summary Estimating forest above‐ground biomass (AGB), or carbon (AGC), in tropical forests has become a major concern for scientists and stakeholders. However, AGB assessment procedures are not fully standardized and even more importantly, the uncertainty associated with AGB estimates is seldom assessed.

Mechanisms of As, Cd, Pb, and Zn hyperaccumulation by plants and their effects on soil microbiome in the rhizosphere

Frontiers in Environmental Science, 2023
Excess potentially toxic elements (PTEs), including arsenic (As), cadmium (Cd), lead (Pb), and zinc (Zn), above permissible limits in the environment, have detrimental effects on trophic levels.

Estimation of Above-Ground Biomass of Wetlands

, 2011
Despite global importance of wetlands, estimations of their production and biomass have received little attention (Campbell et al., 2000). This chapter concentrates on analysis of the composition and above-ground biomass of floodplain grasslands and fen vegetation in the Northern forest zone.

Nondestructive estimates of above‐ground biomass using terrestrial laser scanning [PDF]

Methods in Ecology and Evolution, 2014
Summary Allometric equations are currently used to estimate above‐ground biomass (AGB) based on the indirect relationship with tree parameters. Terrestrial laser scanning (TLS) can measure the canopy structure in 3D with high detail.

Joint Soil and Above-Ground Biomass Characterization Using Radars

IGARSS 2024 - 2024 IEEE International Geoscience and Remote Sensing Symposium
Soil moisture sensing through biomass or vegetation canopy has challenged researchers, even those who use SAR sensors with penetration capabilities. This is mainly due to the imposed extra time and phase offsets on Radio Frequency (RF) signals as they travel through the canopy.

Latitudinal Characteristics of Below- and Above-ground Biomass of Typha: a Modelling Approach [PDF]

Annals of Botany, 2005
The latitudinal differences in the growth characteristics of Typha are largely unknown, although a number of studies have pointed out the effects of climate on the growth and productivity of Typha. Therefore, a dynamic growth model was developed for Typha to examine the effects of latitudinal changes in temperature and radiation on partitioning of the ...

Edge effects on components of diversity and above‐ground biomass in a tropical rainforest [PDF]

Journal of Applied Ecology, 2017
Abstract Edge effects are among the most significant consequences of forest fragmentation. Therefore, understanding the impacts of edge creation on biodiversity is crucial for forest management and biological conservation. In this study, we used trait‐based and phylogenetic approaches to examine the effects of fragmentation on components of ...

Above- and Belowground Biomass Allocation in Shrub Biomes across the Northeast Tibetan Plateau.

PLoS ONE, 2016
Biomass partitioning has been explored across various biomes. However, the strategies of allocation in plants still remain contentious. This study investigated allocation patterns of above- and belowground biomass at the community level, using biomass ...
