Common juniper (Juniperus communis) hosts not many pests or pathogens, but recently increasing needle blight has been observed in Norway. During a survey the needle blight was recorded in many parts of southern Norway but not above 550 m a.s.l., and it has been found both in forests, pastures and gardens. Trees are affected differently; some trees seem to be unaffected, while other trees may be killed. The cause of the disease is a fungus in the family Mycosphaerellaceae hitherto not reported from Norway. In forest pathology literature it has been named Stigmina juniperina, but also Asperisporium juniperinum. However, based on results of molecular sequence analyses it is proposed here that a more appropriate name should be Passalora juniperina (Georgescu & Badea) H. Solheim comb. Nov.
Abstract
Rot fungi are a major problem in the construction sector, and method to study under which moisture and temperature coefficients they grow are therefore of significant interest. Measurements of heat production rate have been made on wood samples with the brown rot fungus Postia placenta at different moisture contents (MCs). The results clearly show the heat production rate (ameasure of respiration rate and fungal activity) is moisture-dependent. For most cases, less heat was produced when the MC was decreased, and more heat was produced when the MC was increased. It was also found that when the MC increased after a dry period, the increase in activity was significantly delayed. However, if the moisture state was then kept constant at a high level, the activity slowly increased, showing that the fungi need time to recover back to the original activity level after drying. Isothermal calorimetry is a measurement technique well suited for the study of the activity of wood-decaying fungi as a function of temperature and moisture content.

Aim of study: The main aim of the work was to summarize availability, quality and comparability of on-going European Research and Monitoring Networks (ERMN), based on the results of a COST FP0903 Action questionnaire carried out in September 2010 and May 2012. Area of study: The COST Action FP0903 involves 29 European countries and 4 non-COST institutions from USA, Morocco and Tunisia. In this study, the total of 22 replies to the questionnaire from 18 countries were included. Materials and methods: Based on the feedback from the Action FP0903 countries, the most popular European Networks were identified. Thereafter, the access to the network database, available quality assurance/quality control procedures and publication were described. Finally, the so-called “Supersites” concept, defined as a “highly instrumented research infrastructure, for both research and monitoring of soil-plant-atmosphere interactions” was discussed. Main results: The result of the survey indicate that the vast majority of the Action FP0903 countries participate in the International Cooperative Programme on Assessment and Monitoring of Air Pollution Effects on Forest (ICP Forest). The multi-disciplinary International Cooperative Programme on Integrated Monitoring of Air Pollution Effects on Ecosystems (ICPIM) is the second most widespread forest programme. Research highlights: To fully understand biochemical cycles in forest ecosystems, long-term monitoring is needed. Hence, a network of “Supersites”, is proposed. The application of the above infrastructure can be an effective way to attain a better integration of research and monitoring networks at forest sites in Europe. Key words: supersites; European Research Monitoring Networks; harmonization; forest.

Changes in the institutional and market environments can present new challenges for organizations. The ability to properly and adequately change and adapt to these new conditions can be crucial for organizations’ competitiveness and their long-term survival. The article offers a qualitative case study analysis on the transformation process of the biggest Finnish dairy organization, Valio, in the light of the country’s accession to the EU. The analysis is based on thirteen personal in-depth semi-structured interviews with management employees, executives, past directors and industry insiders. The examination covers several aspects of the organization’s efforts to adapt with a particular focus on processes, strategies, and transition stages, and thus provides invaluable insight that allows the better understanding of a successful transformation.
