- Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait-based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits-almost complete coverage for 'plant growth form'. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait-environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives.

- Background: Investigations of evolution knowledge and acceptance and their relation are central to evolution education research. Ambiguous results in this field of study demonstrate a variety of measuring issues, for instance differently theorized constructs, or a lack of standardized methods, especially for cross-country comparisons. In particular, meaningful comparisons across European countries, with their varying cultural backgrounds and education systems, are rare, often include only few countries, and lack standardization. To address these deficits, we conducted a standardized European survey, on 9200 first-year university students in 26 European countries utilizing a validated, comprehensive questionnaire, the “Evolution Education Questionnaire”, to assess evolution acceptance and knowledge, as well as influencing factors on evolution acceptance. Results: We found that, despite European countries’ different cultural backgrounds and education systems, European first-year university students generally accept evolution. At the same time, they lack substantial knowledge about it, even if they are enrolled in a biology-related study program. Additionally, we developed a multilevel-model that determines religious faith as the main influencing factor in accepting evolution. According to our model, knowledge about evolution and interest in biological topics also increase acceptance of evolution, but to a much lesser extent than religious faith. The effect of age and sex, as well as the country’s affiliation, students’ denomination, and whether or not a student is enrolled in a biology-related university program, is negligible. Conclusions: Our findings indicate that, despite all their differences, most of the European education systems for upper secondary education lead to acceptance of evolution at least in university students. It appears that, at least in this sample, the differences in knowledge between countries reflect neither the extent to which school curricula cover evolutionary biology nor the percentage of biology-related students in the country samples. Future studies should investigate the role of different European school curricula, identify particularly problematic or underrepresented evolutionary concepts in biology education, and analyze the role of religious faith when teaching evolution.

Basin-scale phenology and effects of climate variability on global timing of initial seaward migration of Atlantic salmon (Salmo salar)
- 2014

- Migrations between different habitats are key events in the lives of many organisms. Such movements involve annually recurring travel over long distances usually triggered by seasonal changes in the environment. Often, the migration is associated with travel to or from reproduction areas to regions of growth. Young anadromous Atlantic salmon (Salmo salar) emigrate from freshwater nursery areas during spring and early summer to feed and grow in the North Atlantic Ocean. The transition from the freshwater ('parr') stage to the migratory stage where they descend streams and enter salt water ('smolt') is characterized by morphological, physiological and behavioural changes where the timing of this parr-smolt transition is cued by photoperiod and water temperature. Environmental conditions in the freshwater habitat control the downstream migration and contribute to within- and among-river variation in migratory timing. Moreover, the timing of the freshwater emigration has likely evolved to meet environmental conditions in the ocean as these affect growth and survival of the post-smolts. Using generalized additive mixed-effects modelling, we analysed spatio-temporal variations in the dates of downstream smolt migration in 67 rivers throughout the North Atlantic during the last five decades and found that migrations were earlier in populations in the east than the west. After accounting for this spatial effect, the initiation of the downstream migration among rivers was positively associated with freshwater temperatures, up to about 10 °C and levelling off at higher values, and with sea-surface temperatures. Earlier migration occurred when river discharge levels were low but increasing. On average, the initiation of the smolt seaward migration has occurred 2.5 days earlier per decade throughout the basin of the North Atlantic. This shift in phenology matches changes in air, river, and ocean temperatures, suggesting that Atlantic salmon emigration is responding to the current global climate changes.

Science and policy on endocrine disrupters must not be mixed : a reply to a "common sense" intervention by toxicology journal editors

Tidskriftsartikel (refereegranskat)abstract
- The "common sense" intervention by toxicology journal editors regarding proposed European Union endocrine disrupter regulations ignores scientific evidence and well-established principles of chemical risk assessment. In this commentary, endocrine disrupter experts express their concerns about a recently published, and is in our considered opinion inaccurate and factually incorrect, editorial that has appeared in several journals in toxicology. Some of the shortcomings of the editorial are discussed in detail. We call for a better founded scientific debate which may help to overcome a polarisation of views detrimental to reaching a consensus about scientific foundations for endocrine disrupter regulation in the EU.

Communication Geography : A Bridge Between Disciplines

- We call for a fundamental restruc turing of research paradigms in geography and media/communication studies to form a bridge between core concerns of the 2 disciplines. This endeavor responds to contemporary historical changes: mediated/mediatized mobility, technological convergence, interactivity, new communication interfaces, and the automation of surveillance. Long-standing concern with a set of issues we call representations, textures, structures, and connections provides a foundation for this interdisciplinary bridge. Integrating these concerns would produce a semi autonomous field, manifested through collaborations between geographers and media theorists.

- Some of the most perceptive contributions to the geographic study of media and communication have been in areas of landscapes studies and geohumanities. To bring landscape and geohumanities insights together more explicitly with communication and media, this progress report draws on George Revill’s concept of an ‘arc of sound’, expanding the concept’s scope to an arc of communication – a dynamic trajectory connecting one vantage point to another through various translations and shifts. It is a mix of integration and translation that forms its own space, place and time, integrating elements of embodied performance, multiple sensory modalities, temporality, absence and excess. Arcs of communication often depend on collaboration and can produce transformations of identity. The concept of the arc of communication enables discovery of numerous threads connecting landscape studies to geohumanities while deepening geographical understandings of media and communication.

- Disconnection is a research topic that attracts increasing amounts of attention. However, there is a lack of research on how different forms of disconnection are related to the production of space and place. This chapter introduces the volume Disentangling: The Geographies of Digital Disconnection, which gathers 12 chapters from different disciplines. Bringing together key insights from the chapters, this introduction overviews the research terrain and presents an agenda for research into the geographies of digital disconnection. It discusses (1) the power geometries of (dis)connection; (2) the existential issues stemming from digitally entangled lives, and (3) how the ambiguities of (dis)connection are accentuated and exposed in time-spaces of social disruption (e.g., during the COVID-19 pandemic). The chapter also proposes disentangling as a complementary term for contextualizing issues of (dis)connection from a social and spatial perspective. Disentangling is ultimately a matter of rethinking and reworking the entangling force of connective media.

- Maps showing immigration into Europe are a potential source of journalistic bias. Limited time and funding to create maps of migration can lead to dependence on data from institutions dedicated to controlling migration, in effect promoting a logic of surveillance directed at immigrants rather than a logic of hospitality based on respect for human rights. There are organizational and logistical barriers to overcome if migration is to be portrayed in ways that support thoughtful, democratic, rights-based deliberation but efforts need to be made to map migration in ways that reveal the geographical experiences of individual immigrants including their movement paths and the risks they face. This article examines unusual maps of migration, drawing on examples from news media as well as from non-governmental organizations, research teams, book authors, private companies, and entertainment media based in several European countries. The examples provide a foundation for concrete recommendations regarding the responsible use of cartographic visualization as a component of immigration news.

Postdigital Territoriality : Disentangling from Digital Media as a Return to Place

- People adopt geographical strategies to distance themselves from digital sociality. Rather than merely turning off devices, they engage in a broader, more durable project of disentangling. This effort responds to the homogenizing, standardizing forces of connective media and their coercive entanglements: socially normalized routines of personal media use, hybridizations of human agency with communication technologies, and digitally mediated activities that generate predictive and prescriptive products. Geographical attention to disentangling is merited by the fact that it comes in local variants and brings questions of place and human territoriality back onto the agenda in significantly new ways as part of a postdigital territoriality. We offer two vignettes revealing place's role as protective, with its territoriality drawing a line around the self. We argue that postdigital territoriality inevitably reflects a differentiated terrain of gender, income, profession, and other elements of positionality.

Disentangling : The Geographies of Digital Disconnection
- 2021

Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- After the rapid rise of digital networking in the 2000s and 2010s, we are now seeing a rise of interest in how people can disentangle their lives from the increasingly pervasive networks of digital communications. This edited volume contributes to the turn toward digital disconnection research by bringing together an interdisciplinary group of authors with expertise in various forms and philosophies of disentangling. By “disentangling” we mean disconnection not just from media but from a digitalized world, a world in which places and landscapes are increasingly structured around digital connectivity. People increasingly look for strategies that will let them reject, avoid, and rework the pervasive media demanding they remain connected at all times. How might we facilitate autonomy from tendrils of digital surveillance, revalue places over dematerialized flows, and unravel digital dependency? Who gets to disconnect and who does not? How do natural cycles such as sleep and death relate to disentangling? Can we clarify the means and objectives of “digital detox”? Can we map the failures, glitches, contradictions, and paradoxes that plague digital connectivity? What does our willing and unwilling entanglement in digital networks say with regard to social resilience and cultural resistance? The book’s three sections start with questions about ethics and justice associated with the power geometries of digital (dis)connection, then move on to consider digitally entangled lives and afterlives, and conclude with a look at the ambiguities of (dis)connection in time-spaces of the COVID-19 pandemic.
