Linking remote sensing, land cover and disease [PDF]

, 2000
Land cover is a critical variable in epidemiology and can be characterized remotely. A framework is used to describe both the links between land cover and radiation recorded in a remotely sensed image, and the links between land cover and the disease ...

Forest canopy analysis in the Alpine environment: comparison among assessment methods

Forest@, 2013
Forest canopy analysis in the Alpine environment: comparison among assessment methods. Forest canopy is an important ecological feature of forest stands and can be expressed as Leaf Area Index (LAI) or canopy cover percentage.

Incorporating Canopy Cover for Airborne-Derived Assessments of Forest Biomass in the Tropical Forests of Cambodia.

PLoS ONE, 2016
This research examines the role of canopy cover in influencing above ground biomass (AGB) dynamics of an open canopied forest and evaluates the efficacy of individual-based and plot-scale height metrics in predicting AGB variation in the tropical forests

Urban Forest Canopy Cover [PDF]

, 2022
Tree canopy cover (TCC) is the total area of tree crowns projected onto the ground. It expresses canopy area as a percentage of total ground area. TCC is commonly used to describe the amount and horizontal distribution of urban forest canopy within a ...

Local hydrodynamics at edges of marine canopies under oscillatory flows. [PDF]

PLoS ONE, 2018
Canopy fragmentation increases both spatial heterogeneity and patch edges which, in turn, is then likely to modify the local hydrodynamics in the canopy.

Natural Variation of NAR5 Determines Nitrogenase Activity and the Yield in Soybean

Advanced Science, EarlyView.
This study identified NAR5, a gene encoding a subtilisin‐like protease, that regulates nitrogenase activity in soybean nodules. Overexpressing NAR5 delayed nodule senescence, enhancing nitrogenase activity, yield, and low‐nitrogen tolerance. The elite haplotype NAR5HapI‐1 linked to superior nitrogenase activity and greater seed weight has been ...

Comprehensive monitoring of Bangladesh tree cover inside and outside of forests, 2000–2014

Environmental Research Letters, 2017
A novel approach for satellite-based comprehensive national tree cover change assessment was developed and applied in Bangladesh, a country where trees outside of forests play an important role in the national economy and carbon sequestration. Tree cover
