Influence of spacing and thinning on wood properties in conifer plantations [PDF]

, 2014
As reported in four appended papers (I-IV), effects of genotype (half-sib family) and initial spacing (I) or initial spacing (II) and various thinning methods (III & IV) on stands and properties of sawn-products were investigated in Scots pine (I & IV ...

Competitive interactions modify the direct effects of climate

Ecography, EarlyView.
As the climate is changing, species respond by changing their distributions and abundances. The effects of climate are not only direct, but also occur via changes in biotic interactions, such as competition. Yet, the role of competition in mediating the effects of climate is still largely unclear.

Landscape and Geography Determine Saproxylic Beetle Captures in Pheromone‐Baited Traps

Entomologia Experimentalis et Applicata, EarlyView.
Pheromone‐baited traps at 39 forest sites across southern Sweden captured 58 saproxylic beetle species, including seven Red‐listed taxa. The effect of surrounding forest cover on beetle abundance may depend on latitude and longitude: positive effects were strongest in warmer southern and eastern regions but weakened or reversed in colder northwestern ...

On Spatial Point Processes With Composition‐Valued Marks

International Statistical Review, EarlyView.
Summary Methods for marked spatial point processes with scalar marks have seen extensive development in recent years. While the impressive progress in data collection and storage capacities has yielded an immense increase in spatial point process data with highly challenging non‐scalar marks, methods for their analysis are not equally well developed ...

Methods for automatic grading of saw logs [PDF]

, 2004
The aim of log grading for pricing is to apply an economic value based on volume and log grade. However, unlike many other commodities logs are hard to characterize into different grades.

The Long Arc of Forest Land Dispossession and Degradation—Firm and State Actions on Sámi Lands in the Wood‐Based Commodity Frontier in Northern Sweden, 1673–1955

Journal of Agrarian Change, EarlyView.
ABSTRACT This article presents a new way of obtaining deep explanations of environmental problems. We expose the production strategies, corporate strategies and state actions that have been taken by firms and state agencies to facilitate the geographical expansion of the wood‐based commodity frontier at the expense of reindeer pastoralists among the ...

Ecological and genomic variation in ectomycorrhizal fungal exploration types

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

Thinning of Norway spruce [PDF]

, 2007
The objective of this thesis was to investigate volume and quality outcome from different thinning strategies in monocultures with Norway spruce. Two different experiments were set up at the Tönnersjöheden experimental forest in south west Sweden.
