Assessing the Relationship between Forest Structure and Fire Severity on the North Rim of the Grand Canyon

open access: yesFire, 2019
While operational fire severity products inform fire management decisions in Grand Canyon National Park (GRCA), managers have expressed the need for better quantification of the consequences of severity, specifically forest structure.

Scenarios for the future Lithuanian State forest sector [PDF]

open access: yes, 2000
Three alternative scenarios to the much debated present organisation of the Lithuanian State forest sector are examined: (i) the integrated, where all functions are delegated to one central administrative authority – the Danish prototype, (ii) the ...

First Detection of Cosmic Microwave Background Lensing and Lyman-{\alpha} Forest Bispectrum

open access: yes, 2016
We present the first detection of a correlation between the Lyman-$\alpha$ forest and cosmic microwave background (CMB) lensing. For each Lyman-$\alpha$ forest in SDSS-III/BOSS DR12, we correlate the one-dimensional power spectrum with the CMB lensing ...

Modelling forest management within a global vegetation model (ORCHIDEE) [PDF]

open access: yes, 2008
Forests have an essential carbon function, removing each year about 20% of global anthropogenic CO2 emissions. Models have been designed to quantify the distribution of CO2 fluxes and ecosystem carbon dynamics at the global scale, but these global ...

Urban, Forest, and Agricultural AIS Data: Fine Spectral Structure [PDF]

open access: yes, 1985
Spectra acquired by the Airborne Imaging Spectrometer (AIS) near Lafayette, IN, Ely, MN, and over the Stanford University campus, CA were analyzed for fine spectral structure using two techniques: the ratio of radiance of a ground target to the radiance ...

Right-handed Hopf algebras and the preLie forest formula [PDF]

open access: yes, 2016
Three equivalent methods allow to compute the antipode of the Hopf algebras of Feynman diagrams in perturbative quantum field theory (QFT): the Dyson-Salam formula, the Bogoliubov formula, and the Zimmermann forest formula.

Spatial Structure Indices of Mature Pedunculate Oak Stands in NW Croatia

open access: yesSouth-East European Forestry, 2013
Background and Purpose: In order to potentiate a valid comparison of forest stands, numerous indices were developed to express forest structure numerically. Each of those indices described a specific measured or calculated value.

Stand Dynamics and Disturbance History of Champlain Valley Clayplain Forests [PDF]

open access: yes, 2017
Studies of stand dynamics can explain how species interactions and disturbances drive forest structure and recruitment patterns of tree species. It is difficult to generate an understanding of stand dynamics and successional trends of forests in areas ...
