Estimation of leaf area index and assessment of its allometric equations in oak forests: Northern Zagros, Iran

Journal of Forest Science, 2012
The focus of the present study is the estimation of leaf area index (LAI) and the assessment of allometric equations for predicting the leaf area of Lebanon oaks (Quercus libani Oliv.) in Iran's northern Zagros forests.

Parallel functional and stoichiometric trait shifts in South American and African forest communities with elevation [PDF]

, 2017
The Amazon and Congo basins are the two largest continuous blocks of tropical forest with a central role for global biogeochemical cycles and ecology. However, both biomes differ in structure and species richness and composition.

Active layer depth and soil properties impact specific leaf area variation and ecosystem productivity in a boreal forest.

PLoS ONE, 2020
Specific leaf area (SLA, leaf area per unit dry mass) is a key canopy structural characteristic, a measure of photosynthetic capacity, and an important input into many terrestrial process models.

Leaf trait plasticity and site-specific environmental variability modulate the severity of visible foliar ozone symptoms in Viburnum lantana.

PLoS ONE, 2022
The assessment of Visible Foliar Symptoms (VFS) is commonly adopted by forest monitoring programs to evaluate ozone impact on vegetation. The occurrence of ozone VFS may differ among individuals of the same species at the same site, and within leaves of ...

Responses in leaf water status of Quercus castaneifolia C.A.Mey and Carpinus betulus L. exposed to cement dust pollution in Northern Iran

Journal of Forest Science, 2023
Industrial air pollution, particularly cement dust, affects the leaf water status and resource utilisation and finally decreases primary production. Evaluating the relative water content (RWC), leaf mass per unit area (LMA), specific leaf area (SLA), and

Environmental Influence on the Untargeted Foliar Metabolome of Naturally Growing Mitragyna Species in Thailand. [PDF]

Plant Environ Interact
ABSTRACT This study investigates the foliar secondary metabolite profiles of four Mitragyna species naturally occurring in Thailand: M. diversifolia, M. hirsuta, M. rotundifolia, and M. speciosa (kratom). Using untargeted gas chromatography–mass spectrometry (GC–MS), 409 secondary volatile metabolites were annotated across the four species.

Specific leaf area responses to environmental gradients through space and time [PDF]

, 2014
Plant communities can respond to environmental changes by altering their species composition and by individuals (within species) adjusting their physiology. These responses can be captured by measuring key functional traits among and within species along

Miniature Robotic Swimmer with Precise 2D Motion Control via Acoustic Vortex‐Induced Propulsion

Advanced Science, EarlyView.
In this work, a miniature robotic swimmer achieves precise 2D motion using sound waves with customized 3D‐printed lenses. Localized acoustic vortices drive both translation and rotation of the swimmer without mechanical parts. This contactless approach offers a novel route to controlled micro‐scale movement, with promising applications in biomedical ...
