- Natural history museums are unique spaces for interdisciplinary research and educational innovation. Through extensive exhibits and public programming and by hosting rich communities of amateurs, students, and researchers at all stages of their careers, they can provide a place-based window to focus on integration of science and discovery, as well as a locus for community engagement. At the same time, like a synthesis radio telescope, when joined together through emerging digital resources, the global community of museums (the 'Global Museum') is more than the sum of its parts, allowing insights and answers to diverse biological, environmental, and societal questions at the global scale, across eons of time, and spanning vast diversity across the Tree of Life. We argue that, whereas natural history collections and museums began with a focus on describing the diversity and peculiarities of species on Earth, they are now increasingly leveraged in new ways that significantly expand their impact and relevance. These new directions include the possibility to ask new, often interdisciplinary questions in basic and applied science, such as in biomimetic design, and by contributing to solutions to climate change, global health and food security challenges. As institutions, they have long been incubators for cutting-edge research in biology while simultaneously providing core infrastructure for research on present and future societal needs. Here we explore how the intersection between pressing issues in environmental and human health and rapid technological innovation have reinforced the relevance of museum collections. We do this by providing examples as food for thought for both the broader academic community and museum scientists on the evolving role of museums. We also identify challenges to the realization of the full potential of natural history collections and the Global Museum to science and society and discuss the critical need to grow these collections. We then focus on mapping and modelling of museum data (including place-based approaches and discovery), and explore the main projects, platforms and databases enabling this growth. Finally, we aim to improve relevant protocols for the long-term storage of specimens and tissues, ensuring proper connection with tomorrow's technologies and hence further increasing the relevance of natural history museums.

- Upon exposure to seawater, euryhaline teleosts need to imbibe and desalinate seawater to allow for intestinal ion and water absorption, as this is essential for maintaining osmotic homeostasis. Despite the potential benefits of increased mixing and transport of imbibed water for increasing the efficiency of absorptive processes, the effect of water salinity on intestinal motility in teleosts remains unexplored. By qualitatively and quantitatively describing in vivo intestinal motility of euryhaline rainbow trout (Oncorhynchus mykiss), this study demonstrates that in freshwater, the most common motility pattern consisted of clusters of rhythmic, posteriorly propagating contractions that lasted ∼1-2 minutes followed by a period of quiescence lasting ∼4-5 minutes. This pattern closely resembles mammalian migrating motor complexes (MMCs). Following a transition to seawater, imbibed seawater resulted in a significant distension of the intestine and the frequency of MMCs increased two to three-fold with a concomitant reduction in the periods of quiescence. The increased frequency of MMCs was also accompanied by ripple-type contractions occuring every 12 to 60 seconds. These findings demonstrate that intestinal contractile activity of euryhaline teleosts is dramatically increased upon exposure to seawater, which is likely part of the overall response for maintaining osmotic homeostasis as increased drinking and mechanical perturbation of fluids is necessary to optimize intestinal ion and water absorption. Finally, the temporal response of intestinal motility in rainbow trout transitioning from freshwater to seawater coincides with previously documented physiological modifications associated with osmoregulation and may provide further insight on the underlying reasons shaping the migration patterns of salmonids.

Seeing like a standard: EU, sustainable biofuels, and land use change in Africa
- 2018
-
Ingår i: ACME: An International E-Journal for Critical Geographies. - 1492-9732. ; 17:1, s. 49-87

Tidskriftsartikel (refereegranskat)abstract
- Biofuels have expanded across the globe, generating a range of concerns in the places of production. One approach to controlling the effects of biofuel production has been sustainability standards. This article takes a 'seeing like' approach to analyse how the EU Sustainability standard contributes to narrowing the vision of what sustainable biofuels are. Six biofuel cases in Africa are examined through the lens of the standard, using remote sensing to investigate the criteria on land use and canopy cover change. The standard view is also compared to on ground views regarding the sustainability of the projects. The effects of seeing like the EU standard are two: 1) diluted seeing, which prioritises global environmental problems over more nuanced social and institutional aspects; and 2) distributed seeing, which transforms standardised sustainable biofuels into multiple, uncertain forms because of hybrid governance. High carbon losses due to biofuel projects were detected, but at the same time, the standard simplifies and skips over wider problems related to unsustainable biofuel projects.

Mismatch Between Scales of Knowledge in Nepalese Forestry: Epistemology, Power, and Policy Implications
- 2012

Ingår i: Ecology and Society. - 1708-3087. ; 17:4

Tidskriftsartikel (refereegranskat)abstract
- The importance of scale dynamics and scale mismatches for outcomes of natural resource management has been widely discussed. In this article we develop theoretically the concept of ‘knowledge scales’ and illustrate it through empirical examples. We define scales of knowledge as the temporal and spatial extent and character of knowledge held by individuals and collectives, and argue that disparate scales of knowledge are an important ‘scale mismatch,’ which together with scale politics, lead to conflicts in Nepalese forest management. We reveal how there are multiple positions within local knowledge systems and how these positions emerge through people’s use of and relations to the forest, in a dynamic interaction between the natural environment and relations of power such as gender, literacy, and caste. Nepalese forestry is a realm in which power and scales of knowledge are being coproduced in community forestry, at the interface of material and symbolic practices in use of forest resources, and in contestations of social-political relations. Further, we reflect upon the importance of clear and precise use of scale concepts and present a methodological approach using triangulation for divergence, enabling researchers and practitioners involved in natural resource management to reveal scale mismatches and politics.

Effects of Aerodynamic Drag and Drafting on Propulsive Force and Oxygen Consumption in Double Poling Cross-Country Skiing
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Purpose This study aimed to investigate the effects of aerodynamic drag and drafting on propulsive force (FPROP), drag area (CDA), oxygen cost (V˙O2), metabolic rate (Ė), and heart rate (HR) during roller skiing on a treadmill in a wind tunnel using the double poling technique. A secondary aim was to investigate the effects of wind versus no-wind test conditions on the same physiological parameters. Methods Ten subjects of each gender participated in the experiments. One pair of skiers of the same gender roller skied simultaneously in line with the air flow; the distance between the skiers was 2.05 m. Each pair was tested as follows: I) with wind, leading; II) with wind, drafting; and III) without wind. The treadmill inclination was 0° throughout the tests. For the wind conditions, the air velocity was similar to the treadmill belt speed: 3 to 7 m·s-1 for men and 3 to 6 m·s-1 for women. Results Drafting resulted in significantly (P < 0.05) lower FPROP,CDA, V˙O2, and Ė, compared with leading, for both genders at racing speed but not at lower speeds, whereas HR was only affected for the male skiers at racing speed. The test without wind resulted in significantly lower FPROP, V˙O2, and Ė at all tested speeds compared with the tests with wind present, whereas HR was lower only at higher speeds. Conclusions At racing speed, but not at lower speeds, the positive effects of drafting behind a skier during double poling were obvious and resulted in a lower FPROP, CDA, V˙O2, Ė, and HR. Tests without wind present put even lower demands on the skiers' physiology, which was also evident at lower speeds.

The sustainability paradox and the conflicts on the use of natural resources

Ingår i: Natural Resource Conflicts and Sustainable Development. Gunilla Almered Olsson, Pernille Gooch (red.). - London : Routledge. - 9781138576896 ; , s. 1-7, s. 1-7

Bokkapitel (refereegranskat)abstract
- The chapter elaborates on the sustainability and sustainable development concepts in relation to the ongoing conflicts on the use of natural resources. The deterioration of natural and biological resources and the climate challenge are related to the current paradigm of economic growth and The 2030 Agenda for Sustainable Development adopted by UN member states in 2015. Conflicts can be seen as opportunities for change as they open up a range of new options and demand innovations for transitions to sustainable alternatives. The ongoing environmental conflict on climate change, a conflict of lifestyle and overconsumption by the few, a conflict on where the different dimensions of equity, in space and over time, intergenerational equity, are at the conflict centre, could be our great opportunity to enter the transition towards a sustainable future. The span of this book is global with case studies from both Global North and South. The themes elaborated and discussed are exemplified in the case studies and have the ambition to represent the major environmental conflicts – although far from exhaustive. The overriding theme of this book, ‘Natural Resource Conflicts and Sustainable Development’, can be sub-divided into three themes: Theme one – human-environment relationship; Theme two – justice and equity dimensions; Theme three – conflict resolution/transformation and pathways towards sustainability
