- Several strains from the genus Trichoderma (Ascomycetes, Hypocreales) are commercially used as biocontrol agents, e.g. in formulations containing the two Trichoderma strains IMI206039 (Hypocrea parapilulifera B.S. Lu, Druzhinina & Samuels) and IMI206040 (T. atroviride P. Karst). To quantify the presence of the two isolates after application, we developed primers for SCAR markers (Sequence-Characterised Amplified Region). In order to quantify both fungal strains simultaneously, we also designed fluorophore-labelled probes distinguishing the two strains, to be used in combination with the SCAR primers. In incubations of two different soils, artificially inoculated and maintained under controlled conditions, the quantification through amplification with the SCAR markers in qPCR and through colony-forming units from plate counting correlated well. Further tests of the markers on samples taken from a golf green treated with a product containing both strains indicated that the two biocontrol strains did not establish, either on the golf green or in the surrounding area.

Non-negative estimation of variance components in heteroscedastic one-way random-effects ANOVA models

Tidskriftsartikel (refereegranskat)abstract
- There is a considerable amount of literature dealing with inference about the parameters in a heteroscedastic one-way random-effects ANOVA model. In this paper, we primarily address the problem of improved quadratic estimation of the random-effect variance component. It turns out that such estimators with a smaller mean squared error compared with some standard unbiased quadratic estimators exist under quite general conditions. Improved estimators of the error variance components are also established.

Evolutionary process of Hordeum brachyantherum 6x and related tetraploid species revealed by nuclear DNA sequences
- 2009

Tidskriftsartikel (refereegranskat)abstract
- A hexaploid form of Hordeum brachlyantherum ssp. brachyantherum was discovered in California in 1980, and its origin has since been studied over the past three decades. We applied EF-G, a nuclear DNA sequence, to infer the parents of the hexaploid form. In polyploid taxa, amplified DNAs were cloned into a vector, and EF-G copies were amplified from the colonies by PCR and digested with restriction enzymes to separate different types. Phylogenetic analysis was performed based on the DNA sequences. The result showed that H. brachyantherum ssp. brachyantherum 6x and 4x carried one identical DNA sequence of 910 bp, and had closely related DNA sequences of 931 bp. H. brachyantherum ssp. brachyantherum 6x and H. marinum ssp. gussoneanum 2x shared one identical DNA sequence of 915 bp. From these results we hypothesized that H. brachyantherum ssp. brachyantherum 6x has evolved by an outcrossing between H. marinum ssp. gussoneanum 2x and H. brachyantherum ssp. brachyantherum 4x, followed by a chromosome doubling. Our results also indicate that H. marinum was involved in the polyploidization of H. secalinum, H. capense, and H. marinum. The origins of H. jubatum and H. depressum are discussed.

Degraded and restituted towns in Poland: Origins, development, problems : Miasta zdegradowane i restytuowane w Polsce. Geneza, rozwój, problemy
- 2015
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- One of the less known problems in settlement geography is the issue of so-called degraded and restituted towns. This lack of reconnaissance, however, is perhaps less the result of the towns’ scarcity than their specificity of being ‘awarded’ or ‘deprived of’ an urban label by means of strictly socio-political actions. Degraded and restituted towns, hence, are spatial units made ‘urban’ or ‘rural’ instantaneously, irrespective of their de facto state along what is widely considered a gradual path of (de)urbanization. Instead, they become compartmentalized into two constructed spatial categories that have survived the onslaught of material transformations and philosophical repositioning through different whims of time. While ‘rural’ and ‘urban’ are conceptual binaries that certainly need to be treated with caution, their cultural salience may cause tangible consequences within national administrative systems that abide by a formalized rural-urban distinction. This issue becomes particularly important for settlements that clearly transcend any imagined rural-urban divide, i.e. those, whose material and immaterial characteristics seem counterfactual to their assigned category. It is also crucial in formal practices designed to avert such counterfactualities, but whose ran-domness of approach more creates confusion than helps straighten out a historical concoction. Both processes, nonetheless, lend ‘urbanity’ and ‘rurality’ a resonance of objectivity, justifying their use as guides for a host of developmental endeavors, despite subverting a much more intricate reality. Degraded and restituted towns are direct derivatives of this. Drawing on the above-mentioned irreconcilabilities, the aim of this book is to present and scrutinize degraded and restituted towns through the example of Poland, where these towns occupy a special niche. For one, Poland, due to its chequered and variegated history, is home to a conspicuously large number of degraded (831) and restituted (236) towns; for another, Poland’s relentlessness of formalizing ‘urbanity’ as a category of statistical, political and cultural guidance has a direct bearing on the lives of the towns’ residents. Realizing the intricacy of degraded and restituted towns in the face of commonplace ru-ral-urban ideations, the editors and the 17 contributing Authors of this book have made an effort to capture the towns’ complexity with special foci on their shrouded origins, developmental specificity and incurred problems. Owing to the involvement of researchers from different scientific disciplines and subdisciplines, the undertaken project has helped elucidate the problem from multiple perspectives: spatial, social, demographic, economic, environmental, historical, architectural, cultural, legal and philosophical. Allocated into 17 chapters, not only have the presented interpretations allowed for a first interdisciplinary synthesis on the topic, but they also helped outline some prospective directions for future research. Moreover, collecting materials of such diversity into an amalgamated whole has helped identify specific discourses that enwrap the concept of “urbanity” when seen through its oscillations within formal contexts, and to which degraded and restituted towns serve as expendable game pieces. By combining knowledge arrived at through ontologically and epistemologically different approaches, the incremental contribution of this book as a whole could be summarized in two attainments: a) extending theoretical frameworks used to study degraded and restituted towns in terms of definition, conceptualization and assessing predispositions for future de-velopment on account of their spatial, legal, socio-economic and historical charac-teristics; b) initiating an anticipated discussion on a number of important and current topics re-lated to the practices of degradation and restitution that have not received adequate attention, e.g., the urbanity-vs.-rurality paradox, the changeability of human settlement forms vs. the consequences of rigid spatial categorizations; the role of various actors in shaping the socio-economic reality under the guise of an ossified binary; or identifying spatio-conceptual conflicts as future challenges for local, regional and national policy.

Economic values in the Swedish nature-based recreation sector : a synthesis

Forskningsöversikt (refereegranskat)abstract
- This research synthesis reports the main findings from a review of economic values associated with nature-based recreation in Sweden. The purpose of the work was to support policy and to identify areas for future research. Data came from over 150 scientific publications and other public sources. The authors find inter alia a lack of systematic data for several recreation activities (including naturebased tourism), a significant growth in the outdoor equipment industry and a relatively modest economic involvement by the public sector. The information is structured under different categories to illustrate the significance and range of different economic values. The authors conclude that there is a need for more comprehensive and systematically collected data, methodological development and interdisciplinary research.
