Considerations and consequences of allowing DNA sequence data as types of fungal taxa
- 2018
-
In: IMA Fungus. - : INT MYCOLOGICAL ASSOC. - 2210-6340 .- 2210-6359. ; 9:1, s. 167-185
-
Journal article (peer-reviewed)abstract
- Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.

Environmental Impacts of ICT: Present and Future
- 2016
-
Doctoral thesis (other academic/artistic)abstract
- ICT is developing rapidly and is playing an increasingly important role in society. High expectations are placed on ICT in relation to sustainable development. In order to provide basis for decision-making and ensure that ICT is used in the best possible way for enabling sustainable development, the sustainability impacts of ICT need to be studied.This thesis aims to provide new knowledge on the environmental impacts related to ICT, to explore the potential of ICT to contribute to sustainability, and discuss ways of assessing environmental impacts of ICT. In order to fulfill the aim a literature review of existing LCA studies of ICT was done, an LCA case study of printed and online media was performed, a methodological framework for sustainability assessment of scenarios was developed and then applied for environmental assessment of future ICT societies.The results show that manufacturing and use phase are the life cycle stages contributing the most to the ICT environmental impacts. For online newspapers online distribution and content production may give significant contribution to the overall impact. User behavior was observed to be crucial for the results of comparisons of ICT solutions with their traditional counterparts.The following key issues were concluded to influence the environmental risks and opportunities in future ICT societies: energy mix, economic conditions, life styles, technology, and environmental ambitions, incentives and regulation. The potential of ICT for sustainability is affected by these key issues.A new methodological framework (SAFS) was developed for the assessment of future scenarios (societal level). Life cycle assessment (LCA) was used for assessment on a product level. Application of both methods, their benefits, drawbacks, and challenges of assessment were discussed. Both types of assessments were concluded to be important to support decision-making.

New entities in Physcia aipolia-P-caesia group (Physciaceae, Ascomycetes) : an analysis based on mtSSU, ITS, group I intron and betatubulin sequences
- 2009
-
In: Annales Botanici Fennici. - 0003-3847 .- 1797-2442. ; 46:1, s. 43-53
-
Journal article (peer-reviewed)abstract
- We have revisited the phylogenetic evaluation of the Physcia aipolia-P. caesia lichen group (sect. Caesiae; Physciaceae, Lecanorales) in order to investigate whether new sequence data and extensive sampling can help us to understand the phylogenetic relationships in that group. We combined partial mtSSU DNA data with two previously used nuclear gene regions (betatubulin, ITS) and a group I intron. We also compared the resulting phylogenies with chemical and morphological characters. Altogether 52 specimens of the P. aipolia-P. caesia group were analysed. Direct optimization of the molecular data revealed several well-supported groups. Our results essentially agreed with those of the earlier studies, and we were able to confirm the independent taxonomic status of some controversial morphotaxa. We also discovered at least two distinct clades that potentially represent species new to science. A new nomenclatural combination, Physcia alnophila (Vain.) Loht., Moberg, Myllys & Tehler, is proposed.

Assessment of media and communication from a sustainability perspective
- 2010
-
Doctoral thesis (other academic/artistic)abstract
- This thesis aims to assess potential environmental impacts of media and communication and to contribute to the development of methods for sustainability assessment. Although the main focus is on printed and electronic media products and environmental impacts, a broader sector analysis is also included and social aspects are discussed. The thesis provides a review of different environmental assessment tools in order to better understand their relationships and the appropriateness of different tools in different situations. Life cycle assessment (LCA) is used to assess printed and electronic versions of newspapers, books and invoices. Results of the screening LCAs of newspapers and books indicate that when comparing printed and electronic versions there are benefits and drawbacks for both. For news and books read on e-reading devices with energy efficient e-ink screens, the main environmental impacts in the studies stemmed from the production of the device and partly from disposal, with the latter having the potential to reduce some environmental impacts through recycling of materials. However, there are data gaps regarding the production of the e-reading devices, most notably for the e-ink screen and the waste management of obsolete e-reading devices. Existing data on internet energy use are uncertain. The potential impacts from a hypothetical total change from paper invoices to electronic invoices in Sweden were assessed through a screening consequential LCA regarding greenhouse gas emissions and cumulative energy demand. The results indicate that emissions and energy demand could decrease as a result of a change. The screening LCAs performed indicate that users’ practices could substantially influence the environmental impacts. Key factors which can influence results and comparisons of printed and electronic media products are total use of electronic devices, total use of printed media, amount and type of paper, energy use of electronic devices, potential printing of electronic media, electricity mix, and the system boundaries set for the assessments. To get a wider perspective, a sector study of the ICT sector and media sector concerning global greenhouse gas emissions and operational electricity use was performed. It was estimated that the contribution to global greenhouse gas emissions in 2007 was roughly 1-2 % for each sector. To assess media and communication products from a sustainability perspective, social aspects should also be covered. The author participated in an international project group on social aspects and LCA, one outcome from which was guidelines for social LCA (S-LCA). In addition to providing guidance for S-LCA, another important role of the guidelines is to facilitate discussions, criticism and proposals for improvement and development of the methodology being developed. The LCA and sector studies in this thesis are limited to direct and to some extent indirect environmental impacts. Further studies of the environmental impacts of more long-term changes in practices and potential structural changes, as well as potential social impacts, could provide important additional insights. This could increase the possibility of facilitating sustainable practices related to ICT and media.

Nordic Lichen Flora Volume 4 – Parmeliaceae
- 2011
-
Editorial collection (other academic/artistic)abstract
- The lichen flora of the Nordic countries, containing about 2000 species, is regarded as one of the best known in the world. Lichenological research of the region has been continuous since the days of Erik Acharius (1757–1819), the ”father of lichenology”, but it is a sad fact that there is no modern flora treatment of the region's impressive lichen flora, the last attempt in the 1870s being that of Th. M. Fries, his major work, Lichenographia scandinavica, unfortunately remained unfinished. A number specialist lichenologists have united forces to produce this much needed Nordic Lichen Flora. This, the fourth volume dedicated to the family Parmeliaceae, includes 152 species, the editors, Arne Thell and Roland Moberg, together with 11 colleagues, treating the 41 genera as separate chapters. The corticolous lichens of the Parmeliaceae are often dominant in the landscape of northern boreal forests, as is the terricolous family Cladoniaceae, the reindeer lichens, the family to be treated in the next volume of the Nordic Lichen Flora.

Mapping surface defects in highly-filled wood fiber polymer composite extrusion from inline spectral analysis
- 2023
-
In: Composites Science and Technology. - 0266-3538. ; 242
-
Journal article (peer-reviewed)abstract
- Surface defects in highly-filled wood polymer composites (WPCs) are mapped in single-screw extrusion via inline optical spectral analysis for the first time. The effects of wood fiber content and drying on the dynamics of surface defects are spatio-temporally resolved via space–time inline optical imaging. Surface tearing appeared from the lowest shear rates investigated followed by a gradual decay in spectral intensity with increasing shear rates/slip velocities. This is accompanied by broadening of the surface tearing characteristic frequency while the average wavelength is estimated to remain constant within the experimental conditions. Increasing shear rates, drying and increasing wood fiber content showed mitigating effects on surface tearing. However, surface tearing in undried samples was still present even at the highest shear rates and high wall slip velocities. A regime where the extrudate surface is dominated by bubbles at high shear rates and low wood fiber contents in undried WPCs was identified.

Surface instability detection in highly-filled biocomposites from inline imaging during extrusion
- 2023
-
In: AIP Conference Proceedings. - 1551-7616 .- 0094-243X. ; 2997
-
Conference paper (peer-reviewed)abstract
- The processing of wood fiber biocomposites, and in particular, the extrusion, is accompanied by multiple challenges, among which agglomeration, entanglement, slip, or surface instabilities being the most common ones. In the current work, we focus on the dynamics of surface instabilities during the single screw extrusion of highly filled wood fiber biocomposites. The biocomposites are polypropylene based with up to 40 wt% wood fiber content of custom compositions based on the commercial-grade by Stora Enso. To detect and quantify the dynamics of surface instabilities, inline image analysis was applied using an optical visualization system positioned at the die exit. Therefrom, space-time diagrams were constructed, and after that, via 2D-Fourier transform analysis, the spatio-tempoal spectral dynamics of the surface instabilities were determined as a function of the die (apparent) shear rate. The spectral dynamics show that melt instabilities of 40 wt% for example, detected via their characteristic (temporal) frequency and (spatial) wavenumber, dissipate with increasing the shear rate, such that at shear rates above ca. 90 1/s, no characteristic frequency and wavenumber can be distinguished i.e. instabilities can no longer be observed on the surface of the extrudates.

Typification of some T. Hedlund names in Sorbus L. (Rosaceae)
- 2006
-
In: TAXON. ; 55:1, s. 203-206
-
Journal article (peer-reviewed)abstract
- Teodor Hedlund was a Swedish botanist who published nearly 50 new names or combinations in Sorbus L. (Rosaceae). Lectotypes are designated for Sorbus arranensis Hedlund, S. minima (Ley) Hedlund, S. quercifolia Hedlund and S. subsimilis Hedlund. The lectotypification of S. anglica Hedlund by A. J. Wilmott is rejected and a new lectotype selected. Notes are given on typification of S. rupicola (Syme) Hedlund. "Sorbus globulifera Hedlund ex Riddelsdell" is not validly published and the material it is based on is part of the variation in S. aria (L.) Crantz.

Enzymatic chip treatment for TMP - Prospects
- 2014
-
In: International Mechanical Pulping Conference, IMPC 2014, part of PulPaper 2014 Conference. - : PI.
-
Conference paper (peer-reviewed)abstract
- In order to evaluate enzyme pre-treatments of chips as means of lowering the energy demand in mechanical pulping, impregnation and refining trials were performed. Wing refining showed that property development was similar to that of reference pulps in the case of pectinase and xylanase while for chips treated with mannanase a less favourable development of the tensile index was noted. Considering the highly increased possibility for enzymatic interactions reached with greater disintegration of chips it could well be that the possibilities for enzymes to attack desired fibre wall structures may have been too few even in the case of Impressafiner treated material used here.
