Distribution pattern of declined Brant`s oak (Quercus brantii Lindl.) trees in forests of Tol-e Ghah, Yasuj [PDF]

تحقیقات جنگل و صنوبر ایران, 2016
A forest stand of 25 ha in Tol-e Gah region nearby Yasuj (Kohgiluyeh and Boyer Ahmad province) was selected to assess the spatial distribution pattern of its dead trees of Brant`s oak (Quercus brantii Lindl).

Impacts of clumping effect on canopy reflectance using 3D radiative transfer modeling

Frontiers in Forests and Global Change, 2023
The product of leaf area index (LAI) and clumping index (CI) quantifies the effective leaf abundance and distribution across the landscape, and therefore, governs the radiation absorption, evapotranspiration, and carbon assimilation processes in the ...

Improving leaf area index (LAI) estimation by correcting for clumping and woody effects using terrestrial laser scanning [PDF]

, 2018
Leaf area index (LAI) has frequently been measured in the field using traditional optical methods such as digital hemispherical photography (DHP). However, in the DHP retrieved LAI, there is always contribution of woody components due to the difficulty ...

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Cutaneous Melanoma Drives Metabolic Changes in the Aged Bone Marrow Immune Microenvironment

Aging and Cancer, EarlyView.
Melanoma, the deadliest form of skin cancer, increasingly affects older adults. Our study reveals that melanoma induces changes in iron and lipid levels in the bone marrow, impacting immune cell populations and increasing susceptibility to ferroptosis.

Fractal index captures the role of vegetation clumping in locust swarming [PDF]

Functional Ecology, 2003
Summary This paper evaluates box‐counting dimension as a quantitative clumping index for discontinuous plant cover, and applies it to studies of both small‐ and large‐scale ecological processes in desert locust (Schistocerca gregaria) swarming. The quadrat under study is tiled with squares of increasing size, and the relationship between the number of

Movement Disorders in Aicardi–Goutières Syndrome and Response to Immunomodulation

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This study characterizes movement disorders and treatment responses in seven children with Aicardi–Goutières syndrome (AGS). We retrospectively evaluated motor phenotypes, neuroimaging, and interferon signatures in patients treated with baricitinib or anifrolumab. Spasticity affected all patients, while dystonia was present in 4/7.

Estimation of Leaf Area Index in a Typical Northern Tropical Secondary Monsoon Rainforest by Different Indirect Methods

Remote Sensing, 2023
The leaf area index (LAI) is a crucial indicator for quantifying forest productivity and community ecological processes. Satellite remote sensing can achieve large-scale LAI monitoring, but it needs to be calibrated and validated according to the in situ
