Stumps of Eucalyptus globulus as a Source of Antioxidant and Antimicrobial Polyphenols

Molecules, 2014
These past years have seen an enormous development of the area of natural antioxidants and antimicrobials. Eucalyptus globulus is widely cultivated in subtropical and Mediterranean regions in intensive short rotation coppice plantations.

Fungal communities in soil beneath Scots pine and their stumps. Effect of fungi on Heterobasidion annosum and Armillaria ostoyae growth

Acta Mycologica, 2014
The soil beneath 30-year-old Scots pines, was inhabited by fungi communities which were at least iwicc as big as communities from ihe 49-year-old stand. The fungi communities in soil beneath the stumps were much smaller compared to those beneath the live

Fungal Diversity in Multiple Post-harvest Aged Red Pine Stumps and Their Potential Influence on Heterobasidion Root Rot in Managed Stands Across Minnesota

Frontiers in Fungal Biology, 2021
Thinning operations that occur in managed red pine (Pinus resinosa) stands, create tree stumps that can serve as a habitat for fungi, especially Heterobasidion irregulare, the cause of a serious root disease. Different fungi can colonize stumps early and

Infection of pre-commercially cut stumps of Picea abies and Pinus sylvestris by Heterobasidion spp. – a comparative study

Silva Fennica, 2018
The aim was to investigate relative susceptibility of stumps of spruce and pine to airborne infections by following pre-commercial thinnings. The proportions of infected stumps and colonized stump surface areas were analysed in 16 forest stands.

Decomposition and nutrient dynamics of stumps and coarse roots of Eucalyptus plantations in southern China

Annals of Forest Science, 2023
Key message Primary remains of Eucalyptus (E. urophylla × E. grandis) plantations following clear-cutting are the stumps and coarse roots. A chrono-sequence approach revealed that the biomass of coarse roots is higher than that of stumps, while they have

Ensemble Learning for Free with Evolutionary Algorithms ? [PDF]

, 2007
Evolutionary Learning proceeds by evolving a population of classifiers, from which it generally returns (with some notable exceptions) the single best-of-run classifier as final result.

Some Light and Temperature Effects on the Behavior of the Adult Pales Weevil, Hylobius Pales (Coleoptera: Curculionidae) [PDF]

, 2017
Adult pales weevils react to light and temperature cues regarding their movements in pine plantations. They remain at the base of their host trees during the day and move onto the trees after dark. A drop in light intensity to 2 fc triggers this response.

Estimating the bioenergy potential of forest chips from final fellings in Central Finland based on biomass maps and spatially explicit constraints

Silva Fennica, 2013
The technical potential of forest chips from final fellings in Central Finland was estimated using a method based on biomass maps derived from a multi-source forest inventory technique.
