Hydrological simulation of a small forested catchment under different land use and forest management
Hydrological Modeling Soil and Water Assessment Tool (SWAT) Atlantic Rainforest Eucalyptus
2024/1/22
The alteration of landscapes by humans has led to a gradual increase in the scarcity of water and degradation of its quality ([24]). Over the last decades, there has been a growing consensus that the ...
Protocol: low cost fast and efficient generation of molecular tools for small RNA analysis
Vector Target mimic miRNA, Cloning Plant Downregulation
2024/1/19
Small RNAs are sequence-dependent negative regulators of gene expression involved in many relevant plant processes such as development, genome stability, or stress response. Functional characterizatio...
Using TLS-Measured Tree Attributes to Estimate above Ground Biomass in Small Black Spruce Trees
terrestrial laser scanning biomass black spruce allometric equations
2023/12/8
Research Highlights: This study advances the effort to accurately estimate the biomass of trees in peatlands, which cover 13% of Canada’s land surface. Background and Objectives: Trees remove carbon f...
An improved theory for calculating leaf gas exchange more precisely accounting for small fluxes
gas exchange leaf von Caemmerer and Farquhar (vCF)
2023/12/8
The widely used theory for gas exchange proposed by von Caemmerer and Farquhar (vCF) integrates molar fluxes, mole fraction gradients and ternary effects but does not account for cuticular fluxes, for...
Forest Dynamics Models for Conservation, Restoration, and Management of Small Forests
simulation model smixed-species models spatially explicit model sempirical models process-based models mechanistic models
2023/11/30
Globally, there are myriad situations in which people aim to conserve, restore, or manage forest ecosystems at small spatial scales of 50 ha or less. To inform management, forest dynamics models provi...
Higher association and integration among functional traits in small tree than shrub in resisting drought stress in an arid desert
Drought adaptation strategies Functional traits Non-structural carbohydrates Photosynthetic and hydraulic traits Trait integration
2023/11/16
Revealing plant adaptation strategies to drought has become one of the research hotspots in assessing the impact of global change on forest ecosystems. However, it is not clear whether the drought ada...
Overexpression of geranyl diphosphate synthase small subunit 1 (LcGPPS.SSU1) enhances the monoterpene content and biomass
LcGPPS.SSU1 monoterpene Litsea cubeba

Litsea cubeba(Lour.) Person, an economically important aromatic plant producing essential oils, has lemon-like fragrance and 96.44–98.44% monoterpene contents. Understanding the rate-limiting enzymes ...
Intact leaf gas exchange provides a robust method for measuring the kinetics of stomatal conductance responses to abscisic acid and other small molecules in Arabidopsis and grasses
Stomatalconductance Kinetics Guardcellphysiology Aquaporin
2024/3/5
Guard cells perceive external and internal stimuli and regulate stomatal conductance in plants. With the use of gas exchange analyzers, time-resolved stomatal conductance responses to light intensity,...
