- Carbonea is a widely distributed genus of lecideoid fungi, including both lichenized and non-lichenized, often parasitic species. We describe the new, non-lichenized species Carbonea tephromelae, based on material collected in the Swedish part of the Scandes. The new species is characterized by a colourless hypothecium, broadly ellipsoid to globose ascospores, and by growing on the thallus of the common saxicolous lichen Tephromela atra. It is similar to the likewise lichenicolous species C. supersparsa and C. vitellinaria, but is clearly separated from these species by anatomy and in a phylogenetic analysis based on four markers (mrSSU, ITS, RPB1, RPB2). Carbonea tephromelae is apparently specific to T. atra, but the use of host specificity as a character for species delimitation in lichenicolous species of Carbonea needs further evaluation.

Combined observational and experimental data provide limited support for facilitation in lichens

- It is increasingly recognized that facilitative interactions can shape communities. One of the mechanisms through which facilitation may operate is when one species facilitates the colonization of another through the exchange of shared symbionts. Lichens are symbiotic associations composed of a mycobiont (lichenised-fungus) and one or two photobionts (algae or cyanobacteria). Different lichen species may have overlapping specificity for photobionts, creating the possibility that facilitation drives lichen community assembly. To investigate whether facilitation occurs in lichens, we combined an observational study (a) with a manipulative field experiment (b). For (a), we quantified the effect of local patch conditions, facilitation and the size of the surrounding metapopulation on colonizations of an epixylic lichen species (Cladonia botrytes) in an area of managed boreal forest. This was done by twice surveying lichens on 293 stumps, located in stands of three age classes. For (b), we treated unoccupied surfaces of 56 cut stumps with algal mixtures of an Asterochloris photobiont and recorded C. botrytes colonizations over three years. In (a), colonization rates of C. botrytes increased with increasing abundance of other lichen species with specificity for Asterochloris photobionts, consistent with an effect of facilitation. However, in the field experiment (b), colonizations of the focal species did not provide support for facilitation. We conclude that our study provides limited support for facilitation in green-algal lichens, underscoring the importance of combining observational studies with experiments when studying species interactions.

Dead branches on living trees constitute a large part of the dead wood in managed boreal forests, but are not important for wood-dependent lichens

- Questions: How much dead wood in the form of dead branches attached to living trees, compared to other types of dead wood, is present in managed boreal forests? Which lichen species grow on this substrate? Location:Two areas of managed coniferous forest in southern Sweden. MethodsWe surveyed the numbers and surface areas of attached dead branches and all other major types of dead wood in 80 stands of managed coniferous forests of various ages and wooded mires. In total, we recorded 5546 dead branches attached to 480 living trees. We also recorded the species of lichens growing on 812 of these dead branches. Results: The surface area of attached dead branches was generally of the same magnitude as that of all other wood types combined. Of the 46 lichen species identified growing on dead branches, 42 were generalist species characteristic of conifer bark and four were wood-dependent specialists. We found no significant difference in lichen species composition between dead branches of Picea abies and Pinus sylvestris, and only small differences in species composition between different stand types and between study areas. There were no clear differences in species composition between the study areas. Conclusions:Although overlooked, attached dead branches constitute a significant proportion of all dead wood available in boreal forests. However, the lichen communities on these branches mainly consist of generalist species. Lichens on attached dead branches thus do not seem to contribute strongly to the species pool of wood-dependent lichens in managed boreal forests.

Digitalization and Privacy : A systematic literature review
- 2016
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The research area of Digitalization and Privacy, as defined and delimited within the context of this knowledge review, (mainly through the selection of search strings), is in a phase of development. The present study has been delimited to articles in English that have been published in scientific peer-reviewed journals. During the past ten years, the number of scientific articles per year has increased more than five times. For example, a search of the database WEB OF SCIENCE for the year 2006 renders 13 matches, while an identical search for the year 2014 renders 72 matches. In the present systematic knowledge review, two types of investigations have been conducted. First, a bibliometric analysis that aims to produce a comprehensive overview of the current state of the research in the area at a statistically analytical level. Second, a systematic literature study that has identified relevant scientific articles, analyzed their content and categorized them. The bibliometric analysis demonstrates that research on digitalization and privacy is quite strictly divided, mainly between three scientific fields. In other words, communication between the various fields (i.e., intertextual references and citations of each field’s research) is somewhat limited. The research fields can be described as: (a) a technical field that is largely concerned with systems development, (b) a legal field that focuses on issues regarding legislated protection of privacy, and (c) a social sciences and behavioral sciences oriented area that includes informatics, psychology, sociology, political science and marketing and management research and more. This systematic literature review, based on close reading of all included articles, shows a lack of clear, mutually shared, conceptual terminology and common understandings of methodologies within the various scientific disciplines. However, there are a number of areas (or focuses of research) that recur frequently. The five dominant areas are: (a) technology, (b) legislation, (c) the state, (d) theory, and (e) working life. Further, the research identifies different approaches to digitalization and privacy. First, as a problem (or, perhaps, a challenge) that can be managed using new, improved and more privacy-sensitive technology. Secondly, as an opportunity to work towards achieving good values such as improved health, through practical applications of potentially sensitive data. Thirdly, as a threat to citizens and employees. And, finally, as a relationship of ex-change between usefulness and risks, for example, with regards to state needs for information in order to prevent threats and protect the citizens rights of privacy. It is also strikingly clear that there is insufficient knowledge of the relation-ship between digital surveillance and potential behavioral changes in society. Various studies highlight that a lack of respect for privacy risks leading to reduced Internet use and reduced political involvement (at least on the Internet). However, at this point in time there is no empirical evidence to support that this is the case.

Tidskriftsartikel (refereegranskat)abstract
- Den här artikeln behandlar arbetsmiljöfrågor relaterade till migrantarbete inom den gröna näringen (jordbruket) och då särskilt säsongsarbete. Syftet med studien är att utifrån internationella erfarenheter identifiera och beskriva centrala problemområden för framtida forskning. Fokus ligger på diskriminering och psykosocial ohälsa, två områden som har pekats ut som särskilt angelägna i den internationella forskningen om migrantarbetare i jordbruket.

Diskriminering och psykosocial ohälsa : migrantarbetare i jordbruket

Tidskriftsartikel (refereegranskat)abstract
- Den här artikeln fokuserar arbetsmiljöfrågor relaterade till migrantarbete inom den gröna näringen (jordbruket), och då särskilt säsongsarbete. I synnerhet lyfter artikeln fram den diskriminering och psykosociala ohälsa som i hög utsträckning drabbar migranterna. Eftersom det i dagsläget inte finns någon publicerad forskning avseende nutida förhållanden i Sverige så bygger slutsatserna till stor del på en genomgång av vetenskapliga publikationer avseende situationen i andra jämförbara länder.
