1582. Worldwide genetic structure elucidates the Eurasian origin and invasion pathways of Dothistroma septosporum, causal agent of Dothistroma needle blightMartin S. Mullett, Rein Drenkhan, Kalev Adamson, Piotr Boroń, Anna Lenart-Boroń, Irene Barnes, Michal Tomšovský, Zuzana Jánošíková, Katarína Adamčíková, Emília Ondrušková, Barbara Piškur, Tine Hauptman, 2021, original scientific article Abstract: Dothistroma septosporum, the primary causal agent of Dothistroma needle blight, is one of the most significant foliar pathogens of pine worldwide. Its wide host and environmental ranges have led to its global success as a pathogen and severe economic damage to pine forests in many regions. This comprehensive global population study elucidated the historical migration pathways of the pathogen to reveal the Eurasian origin of the fungus. When over 3800 isolates were examined, three major population clusters were revealed: North America, Western Europe, and Eastern Europe, with distinct subclusters in the highly diverse Eastern European cluster. Modeling of historical scenarios using approximate Bayesian computation revealed the North American cluster was derived from an ancestral population in Eurasia. The Northeastern European subcluster was shown to be ancestral to all other European clusters and subclusters. The Turkish subcluster diverged first, followed by the Central European subcluster, then the Western European cluster, which has subsequently spread to much of the Southern Hemisphere. All clusters and subclusters contained both mating-types of the fungus, indicating the potential for sexual reproduction, although asexual reproduction remained the primary mode of reproduction. The study strongly suggests the native range of D. septosporum to be in Eastern Europe (i.e., the Baltic and Western Russia) and Western Asia.

1590. A system for quality assessment of forestry contractorsMatevž Triplat, Nike Krajnc, 2021, original scientific article Abstract: Skilled contractors are needed to meet the increased demand for wood and to maintain a competitive edge in forestry. The structure of the forest industry has changed significantly. Today%s situation favours smaller contractors that are more flexible. Worldwide contractors are important for forest operations, but there is often limited knowledge about how well they fulfil demands about resource efficiency, social responsibility and environmental protection. The aim of this paper is to present the guidelines for the assessment of forestry contractors following sustainability principles and to present a recently developed system. In addition to the requirements for professional competences and legislative obligations, the system proposes a number of additional requirements such as corporate social responsibility, participation in the local community and greater environmental responsibility. The forestry contractor and the certification body sign a cooperation agreement to obtain the expert assessment. The expert assessment is performed by an evaluator authorised by a certification body. A web service has been introduced with the purpose of serving as a communication tool between professional evaluators and forestry contractors, as well as providing a new possibility for forest owners to get direct contact with forestry contractors. The system enables its users to exert influence on the assessment of forestry contractors by assessing the quality of their services. Private forests would greatly benefit from customer feedback information on the service quality. By now, 1584 forest contractors have registered in Slovenia, where 67% provide the service of cutting and skidding, 8% provide woodchipper service, 7% transport of round wood, 5% cable crane yarding and 4% fully mechanised harvesting. Until June 2020, 142 forest contractors have gone through the process of quality assessment.
