(Springer Science and Business Media LLC, 2019-04-29)The integrated forest ecosystem model ForSAFE-Veg was used to simulate soil processes and understory vegetation composition at three—sugar maple, beech, yellow birch—hardwood forest sites in the Northeastern United States (one at Hubbard Brook, NH, and ... -
(Inter-Research Science Center, 2017-12-27)As the world’s social-environmental problems increasingly extend across boundaries, both disciplinary and political, there is a growing need for interdisciplinarity, not only in research per se, but also in doctoral education. We present the common ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-10)Climate warming in sub-Arctic regions leads to shifts in plant communities and retreating glaciers. Mosses and lichens contribute to important ecosystem processes in these environments, including nitrogen fixation via their microbiome. The first objective ...
-
(Wiley, 2020-08-20)Marine ecosystems, particularly in high-latitude regions such as the Arctic, have been significantly affected by human activities and contributions to climate change. Evaluating how fish populations responded to past changes in their environment is ...
-
(Elsevier BV, 2020-12)Human economic activities and following carbon emissions have been recognized to be a real threat to the environment. The current levels of consumption-based carbon footprints in all developed economies grossly exceed the sustainable level. Scientists ...
-
(Springer Nature, 2016-06-02)Climate change studies have detected earlier spring arrival of breeding birds. However, first nest dates (date first nests were found), which commonly provide the metric for earlier arrival, can be biased by population size or sampling effort. Our aims ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2018-12-14)Krill are an important component of the Icelandic marine ecosystem. Given their important ecological niche, as conveyors of biological production between phytoplankton and higher trophic levels, fluctuations in krill abundance can have large impacts ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Civil and Environmental Engineering, 2021-08)The consumption activities of urbanites contribute to an ever-increasing share of greenhouse gas emissions and resource depletion. As urban form influences behaviours, the search for the most sustainable type of urban form is a research topic of interest. ...
-
(MDPI AG, 2019-11-12)Transport is a key sector in reducing greenhouse gas (GHG) emissions. A consensus prevails on a causal relationship between distance to the city center and emissions from private transport, which has led to an emphasis on density in urban planning. ...
-
(Springer Nature, 2017-12-18)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 ...
-
(Copernicus GmbH, 2019-04-03)The flow regimes of glacier-fed rivers are sensitive to climate change due to strong climate cryosphere hydrosphere interactions. Previous modelling studies have projected changes in annual and seasonal flow magnitude but neglect other changes in river ...
-
(Cambridge University Press (CUP), 2019-04-11)Mass-balance measurements of Icelandic glaciers are sparse through the 20th century. However, the large archive of stereo images available allows estimates of glacier-wide mass balance in decadal time steps since 1945. Combined with climate records, ...
-
(Agricultural University of Iceland, 2016)This article describes how natural geothermal soil temperature gradients in Iceland have been used to study terrestrial ecosystem responses to soil warming. The experimental approach was evaluated at three study sites in southern Iceland; one grassland ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-10)Climate change constitutes one of the most pressing challenges faced by tourism today. Tourism research on climate-induced environmental changes has contributed to an increase in knowledge about adaptation during the last decade. Despite a general ...
-
(Copernicus GmbH, 2018-07-06)Glacio-hydrological models (GHMs) allow us to develop an understanding of how future climate change will affect river flow regimes in glaciated watersheds. A variety of simplified GHM structures and parameterisations exist, yet the performance of these ...
-
(Springer Science and Business Media LLC, 2020-01-18)Vegetation change has consequences for terrestrial ecosystem structure and functioning and may involve climate feedbacks. Hence, when monitoring ecosystem states and changes thereof, the vegetation is often a primary monitoring target. Here, we summarize ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Civil and Environmental Engineering, 2023)Snow resources worldwide are undergoing extensive changes in response to widespread and rapid changing of the global climate. These resources are vital in many areas and changes to them have and will continue to impact human societies and ecosystems ...

(Guðfræðistofnun Háskóla Íslands, 2017)„Loftslagsbreytingar er vandamál sem ekki er hægt að leysa!“ Það eru orð guðfræðingsins og siðfræðingsins Willis Jenkins sem þessi grein beinir sjónum að. Hvað sem þessum orðum líður heldur Jenkins því fram að kristin siðfræði á tímum loftslagsbreytinga ...

(University of Iceland Press, 2006)Hnattræn hlýnun (global warming) er eitt mest umrædda málefni í heiminum í dag, enda er hlýnunin þegar farin að hafa gífurlegar afleiðingar. Mikil gögn liggja fyrir um hvernig þættir veður- og náttúrufars eru að breytast. Gefur bókin gott yfirlit yfir ...

(American Geophysical Union (AGU), 2019-12-03)The Central Asian Pamir Mountains (Pamirs) are a high-altitude region sensitive to climatic change, with only few paleoclimatic records available. To examine the glacial-interglacial hydrological changes in the region, we analyzed the geochemical ...
