Forces required to vertically uproot tree stumps [PDF]

open access: yesSilva Fennica, 2010
Stumpwood attracts renewed interest due to increased use of forest biomass for bioenergy. In Nordic countries stumps are generally uprooted with crawler excavators, which have strong cranes (ca. 400 kNm gross lift torque), but are not designed for moving

The effect of size of black cherry stumps on the composition of fungal communities colonising stumps

open access: yesOpen Life Sciences, 2019
We investigated fungal communities colonising black cherry stumps. We tested the hypothesis that black cherry stumps of greater diameter should be characterised by more diverse fungal communities than stumps of smaller diameter. The material for analyses

Trees, Stumps, and Applications [PDF]

open access: yesAxioms, 2018
The traditional derivation of Runge–Kutta methods is based on the use of the scalar test problem y′(x)=f(x,y(x)). However, above order 4, this gives less restrictive order conditions than those obtained from a vector test problem using a tree-based theory. In this paper, stumps, or incomplete trees, are introduced to explain the discrepancy between the

Cut stumps vs broken stumps: Does it make any difference in the maintenance of plant and lichen biodiversity in Central European mountain forests?

open access: yesForest Ecosystems
Excessive forest exploitation significantly contributes to land degradation and the creation of human-made deadwood. Stumps are sometimes ignored in studies on the biodiversity of coarse woody debris.

Bioinformatic analysis of cytokine expression in the proximal and distal nerve stumps after peripheral nerve injury

open access: yesNeural Regeneration Research, 2021
In our previous study, we investigated the dynamic expression of cytokines in the distal nerve stumps after peripheral nerve injury using microarray analysis, which can characterize the dynamic expression of proteins.

Tree regeneration on stumps in second-growth temperate rainforests of British Columbia, Canada

open access: yesGlobal Ecology and Conservation, 2022
The significance of stumps and other coarse woody debris in maintaining biodiversity has been widely recognized in temperate rainforests, however, there is a paucity of research on the role of stumps in tree regeneration.

Mycobionta of birch and birch stump roots and its possible effect on the infection by Armillaria spp. II.

open access: yesActa Mycologica, 2014
This paper presents the differences in size and structure of mycobionta communities occurring in soil and on/i n roots of a 30 year-old birch and its stumps 2 years after cutting of the trees.

Forests of Stumps

open access: yes, 2021
Many numerical studies (Hansen and Salamon (1990), Schapire (1990)) indicate that bagged decision stumps perform more accurately than a single stump. In this work, we will investigate two approaches to create a forest of stumps for classification.
