The primary goal of this study was to investigate how the radial growth of retained trees responds after thinning-from-above. The National Board of Forestry which initiated this study, was interested in whether there were differences in the growth-response between the tree …
… the rehabilitation work. Functional traits for plants are traits that affect growth, reproduction and survival and hence the plants fitness to the environment. Tree species used to be grouped after their demand for light and growth pattern. Light demanding pioneer species often …
Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and …

… acidification. Nevertheless, the ash does not result in any increase of tree growth if it is added on mineral soils, which is where the measure is most commonly used in Sweden. Due to the lack of growth response, the interest from landowners is small, which is why ash amendment …
… caused by the cutting operation. Positive effects are for example a valuable growth in the remaining trees and increased biological di-versity. This study is based on a total of 79 trees from 4 different treatments in a spruce shelterwood, cut in 1994, in the middle of Sweden …
… in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce. In addition a complementary greenhouse …
… Parameter values for each of the different physiological stages in microbial growth, base respiration, substrate induced respiration, exponential growth (my) and lag time, was extracted from the data. The results indicateted differences in the temperature response both for the …
… has led to increased use of several silvicultural measures that improve stand growth. Such a measure is ditch cleaning, which means that existing ditches or ditch networks are cleared and restored. The purpose of this is to retain or regain the original drainage capacity of the …
Female growth, number of eggs and egg growth of Daphnia pulex were studied at four temperatures, 12, 16, 18 and 20°C. I hypothesized that female growth and number of eggs would be lower and the size of the eggs larger in the presence of a predator (kairomones) than in its …
… condition has the same quick response, and to what extent fast economic growth brings changes in the cause of death statistics. Method and material. Seven countries were chosen based on their fast economic growth. Data about the countries economic development(GDP(PPP)/c) were …

… analysis on return on equity, return on assets, profit margin, revenue growth, net sales and success factors was carried out. Results & Conclusions: By using qualitative and quantitative methods, we identified some group factors (forward quest, soft values, knowledge/skills, and …
Fibroblast growth factors are signaling peptides that controls important cellular processes such as proliferation, differentiation, migration, adhesion and survival. Through binding to different types of receptors on the cell surface, these peptides can have different effect on …
… infection, having an infection efficiency of only 1.2%. At the same time, the growth of this knock out strain was inhibited when grown in prox-imity to L. pneumophila. This could indicate that there are miRNA(s) that are in-volved in the amoeba’s response to bacterial …
