TL;DR: In this article, a review of the literature on private forest owners' typologies based on owners' objectives was conducted, and the authors found that forest owners whose objectives are timber production and who are business-oriented are more likely to manage and harvest their stands.
Abstract: There are many factors that determine what forestry activities forest owners carry out in their forest properties and that influence whether forest owners engage in entrepreneurial activity. This paper explores whether the values and objectives of forest owners influence their forestry behaviour and their engagement in entrepreneurial activity. This is done through a review of the literature on private forest owners’ typologies based on owners’ objectives. The review reveals that typologies typically divide forest owners into two main groups. The primary objective of the first group of owners is production (of wood and non-wood goods and services) usually, although not exclusively, so as to generate economic activity. The primary objective of the second group is consumption (of wood and non-wood goods and services). There is a tacit assumption in the studies reviewed that goals and objectives do influence forestry behaviour but few studies have actually assessed whether this is the case. The general finding is that forest owners whose objectives are timber production and who are business-oriented are more likely to manage and harvest their stands. No research focusing on the link between owners’ objective and wider entrepreneurial activity in forests was found.

TL;DR: The spruce bark beetle, Ips typographus, was induced to attack Norway spruce by means of pheromone dispensers and the trees were later categorized as surviving or dying, according to the degree of sapwood blue-staining caused by the attacks.

TL;DR: Among the four species, Quercus macrolepis sustained the highest stomatal conductance despite very low water potentials, thus overcoming drought by means of desiccation tolerance, and quercus frainetto was the least drought-resistant of theFour species.
Abstract: Effects of water stress on phenology, growth, stomatal activity and water status were assessed from April to November 1996 in 2-year-old seedlings of Quercus frainetto Ten. (Quercus conferta Kit.), Quercus pubescens Willd., Quercus macrolepis Kotschy (Quercus aegilops auct.) and Quercus ilex L. growing in containers in northern Greece. All four species developed more than 50% of their total leaf area before the beginning of June--an adaptation to arid climates. Well-irrigated plants tended to develop greater individual leaf area, number of leaves per plant, total plant leaf area, height and root:shoot ratios than water-stressed plants, but the difference between treatments was not significant for any parameter in any species. Quercus macrolepis appeared to be the most drought-tolerant of the four species. It maintained the highest number of leaves of the smallest size and increased the proportion of fine roots during drought. In all species, drought caused significant decreases in stomatal conductance and predawn and midday water potentials from mid-July until the end of August, when the lowest soil water content and highest mean daily air temperatures and midday leaf temperatures occurred; however, the responses were species-specific. Among the four species, Quercus macrolepis sustained the highest stomatal conductance despite very low water potentials, thus overcoming drought by means of desiccation tolerance. Quercus ilex decreased stomatal conductance even before severe water stress occurred, thereby avoiding desication during drought. Quercus pubescens had the highest water potential despite a high stomatal conductance, indicating that its leaf water status was independent of stomatal activity. Quercus frainetto was the least drought-resistant of the four species. During drought it developed very low water potentials despite markedly reduced stomatal aperture.

TL;DR: This analysis shows that direct hydrogen bonding between PSM and Chol does not provide an adequate explanation for their putative specific interaction, and a combination of charge-pairing, hydrophobic, and van der Waals interactions leads to a lower tilt in PSM neighboring Chol than in Chol with only POPC neighbors.

TL;DR: In this article, the potential stem wood production for Norway spruce was estimated for different regions in Sweden by using basic physiological relationships of intercepted radiation versus biomass production and knowledge of how a water deficit reduces the potential production, derived from results of field experiments on nutrient optimization.
