    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 ...
  • Silva, Teresa Sofia Giesta da (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 ...

    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. ...

    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 ...

    1. Human activities have caused global changes of atmospheric chemistry resulting in increased temperature especially in the colder regions of the northern hemisphere. Since warming of the environment can have drastic effects on terrestrial ecosys-tems ...

    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 ...

    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, ...
