A process-based model of conifer forest structure and function with special emphasis on leaf lifespan [PDF]

, 2002
We describe the University of Sheffield Conifer Model (USCM), a process-based approach for simulating conifer forest carbon, nitrogen, and water fluxes by up-scaling widely applicable relationships between leaf lifespan and function. The USCM is designed

Determination of the number of sapwood annual rings in oak in the region of southern Moravia

Journal of Forest Science, 2006
The paper deals with the determination of the number of sapwood annual rings in oak (Quercus sp.) in relation to altitude, locality and stand age. Several different groups of samples were used from two localities of southern Moravia.

A Comparison of Unbleached Pulps from Cherry Heartwood and Sapwood [PDF]

, 1978
The purpose of the project was to evaluate pulps made from cherry heartwood and sapwood. The amount of heartwood a tree has is an individual trait of the tree rather than a function of geography or environment.

Observations of the Gallery Habits of \u3ci\u3eTrypodendron Retusum\u3c/i\u3e (Coleoptera: Scolytidae) Infesting Aspen in Central Michigan [PDF]

, 2017
A monogamous pair of adult Trypodendron retusum construct a gallery system consisting of an entrance tunnel and from two to five lateral tunnels into the sapwood of aspen. Inoculation of the mutualistic fungus Ambrosiella ferruginea by the female beetle,

Community dynamics of lignicolous lichens on standing deadwood in a 275‐year chronosequence

Oikos, EarlyView.
Dead trees provide discrete habitat patches in which patch quality changes gradually due to wood decomposition. Although in most cases these patches persist for not more than a few decades, in some ecosystems deadwood decomposition and the consequent change in habitat patch quality can be a centuries‐long process, potentially leading to dynamics of ...

Metabonomics Analysis of Stem Extracts from Dalbergia sissoo

Molecules, 2022
Dalbergia sissoo is a woody plant with economic and medicinal value. As the pharmacological qualities and properties of the wood from this plant primarily depend on its extractives, in this study, the metabolomic analysis of extractives from its stems ...

Assessment of wood microstructural changes after one-stage thermo-hydro treatment (THT) by micro X-ray computed tomography [PDF]

, 2015
The microstructural changes in a selection of softwoods and hardwoods resulting from thermo-hydro treatment (THT) at 160°C were examined by means of a state-of-the-art micro X-ray computed tomography.

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Chemical changes of polysaccharides in heat-treated European beech wood

Journal of Wood Science
This work deals with the influence of different heat treatment temperatures (140, 150, 160, 170, 180, 190, 200, and 210 °C) on changes in sapwood and red heartwood of European beech (Fagus sylvatica L.). According to the results of wet chemistry methods,
