Í þeirri lýðræðisvakningu sem varð á Íslandi eftir hrun mátti sjá hvernig ólíkir hópar byggðu lýðræðiskröfur og ákall um meira eða dýpra lýðræði á ólíkum hugmyndum um lýðræði. Kjarni þessara krafna var þó hinn sami: meira lýðræði þýddi aukin áhrif almennings á ákvarðanir og stefnumótun. Þannig undirstrikaði hin almenna umræða um lýðræði þann skilning að virkt samráð við almenning sé nauðsynlegur hluti lýðræðislegra stjórnarhátta. Í þessari grein er gerð tilraun til að varpa ljósi á ólíkt inntak lýðræðiskröfunnar eftir málefnum hverju sinni og athyglinni einkkum beint að þekkingarmiðuðu lýðræði. Því er haldið fram að þótt enn sé ekki hægt að segja að þekkingarmiðað lýðræði byggi á veigamiklum empíriskum rökum, þá bjóði það upp á áhugaverðustu leið samtímans til að hugsa um lýðræðisnýjungar. ; During the democratic awakening in Iceland during and after the financial crisis of 2008 it was evident that different groups based their demands for more or deeper democracy on different conceptions of democracy. Yet their demands had a common core: more democracy meant greater public influence on policy- and decision-making. Thus public discussion insisted on a conception of democracy according to which public consultation is a necessary part of democratic governance. This paper discusses different kinds of consultation depending on the particular demands in each case with particular emphasis on epistemic democracy. I argue that even though it can hardly be said that epistemic democracy is based on much empirical evidence yet, its approach is the most promising way to think about future democratic. ; Peer Reviewed ; Ritrýnt tímarit
Authorities all over the world have faced enormous challenges in dealing with the COVID-19 pandemic, including how to circulate up-to-date and accurate information to the general public concerning the novel coronavirus. In light of this, there has been much focus on studying information dissemination regarding COVID-19. Most of the attention in this communication research has been on large states such as the United States and the United Kingdom but smaller states like Iceland have mostly been absent in these studies. The aim of this article is twofold. First, it adds the Icelandic case to the COVID-19 communication research literature by examining findings from two representative surveys that were conducted in Iceland in June and August 2020 concerning COVID-19 and information dissemination, and how these findings compare to similar studies from larger states. Second, building on limited existing academic work on political communication in small states, I explore how the dissemination of information concerning the COVID-19 pandemic might be, to some extent, different in Iceland than in larger states because of the size variable. ; peer-reviewed
Global warming is widely predicted to reduce the biomass production of top predators, or even result in species loss. Several exceptions to this expectation have been identified, however, and it is vital that we understand the underlying mechanisms if we are to improve our ability to predict future trends. Here, we used a natural warming experiment in Iceland and quantitative theoretical predictions to investigate the success of brown trout as top predators across a stream temperature gradient (4–25 °C). Brown trout are at the northern limit of their geographic distribution in this system, with ambient stream temperatures below their optimum for maximal growth, and above it in the warmest streams. A five-month mark-recapture study revealed that population abundance, biomass, growth rate, and production of trout all increased with stream temperature. We identified two mechanisms that contributed to these responses: (1) trout became more selective in their diet as stream temperature increased, feeding higher in the food web and increasing in trophic position; and (2) trophic transfer through the food web was more efficient in the warmer streams. We found little evidence to support a third potential mechanism: that external subsidies would play a more important role in the diet of trout with increasing stream temperature. Resource availability was also amplified through the trophic levels with warming, as predicted by metabolic theory in nutrient-replete systems. These results highlight circumstances in which top predators can thrive in warmer environments and contribute to our knowledge of warming impacts on natural communities and ecosystem functioning. ; The authors are supported by grants awarded by NERC (NE/L011840/1 and NE/ I009280/2), the Royal Society (RG140601), the British Ecological Society (4009-4884), the Fisheries Society of the British Isles, the Grand Challenges in Ecosystems and the Environment initiative at Imperial College London, the Scottish Government Rural and Environment Science and ...
Global change threatens invertebrate biodiversity and its central role in numerous ecosystem functions and services. Functional trait analyses have been advocated to uncover global mechanisms behind biodiversity responses to environmental change, but the application of this approach for invertebrates is underdeveloped relative to other organism groups. From an evaluation of 363 records comprising >1.23 million invertebrates collected from rivers across nine biogeographic regions on three continents, consistent responses of community trait composition and diversity to replicated gradients of reduced glacier cover are demonstrated. After accounting for a systematic regional effect of latitude, the processes shaping river invertebrate functional diversity are globally consistent. Analyses nested within individual regions identified an increase in functional diversity as glacier cover decreases. Community assembly models demonstrated that dispersal limitation was the dominant process underlying these patterns, although environmental filtering was also evident in highly glacierized basins. These findings indicate that predictable mechanisms govern river invertebrate community responses to decreasing glacier cover globally. ; This work was funded by the following organisations: The UK Natural Environment Research Council grants and studentships GR9/2913, NE/E003729/1, NE/E004539/1, NE/E004148/1, 20 NE/G523963/1, NER/S/A/2003/11192, and NE/L002574/1; the European Union Environment and Climate Programme Arctic and Alpine Stream Ecosystem Research (AASER) project (ENV-CT95-0164); EU-FP7 Assessing Climate impacts on the Quality and quantity of WAter (ACQWA) project (212250); Icelandic Research Council (954890095, 954890096); University of Iceland Research Fund (GMG96, GMG97, GMG98), Wyoming Center for Environmental Hydrology and Geophysics-National Science Foundation (1208909); USA-Wyoming NASA Space Grant Faculty Research Initiation (#NNX10A095H); USA-NSF Wyoming Epscor; Nationalpark Hohe Tauern, Austria; the Royal Society (International Outgoing Grant 2006/R4); the Leverhulme Trust; the Universities of Leeds, Birmingham, Iceland and Innsbruck; European Centre for Arctic Environmental Research (ARCFAC): a Research Infrastructures Action of the European Community FP6 (026129-2008- 72); the Stelvio National Park (2000-2001); the Autonomous Province of Trento (HIGHEST project, 2001-2004, del.
