Longitudinal variation of macroinvertebrate assemblages in Icelandic arctic glacier-fed and snow-fed streams: changes and their environmental drivers – a comparison after 26 years - Climate-induced retreat of glaciers will affect the macroinvertebrate composition in glacier‐fed rivers and lead to an increase in α-diversity and abundance as well as to an upward migration of downstream macroinvertebrates. In Arctic regions, where climate change is expected to cause major environmental changes, snow is becoming increasingly important for aquatic ecosystems, and the influence of glacier meltwater is declining. The consequences for macroinvertebrate composition are still largely unresolved, mainly because long-term studies in Arctic regions are also lacking. Therefore, this research project will investigate temporal changes in macroinvertebrates along an Arctic glacier-fed river and a snow-fed river on the basis of Gíslason et al. (2001) who mapped macroinvertebrate, hydrophysical and -chemical parameters in 1996 and 1997 along the arctic rivers Vestari- and Austari-Jökulsá River. Since these first investigations the hydrological and climatic conditions have changed significantly. This intensive cross-scale study of the hydrobiological and biogeochemical properties of two Arctic streams with different hydrology and their spatial and temporal dynamics will close the knowledge gap regarding the long-term change of longitudinal variation of macroinvertebrate communities in arctic glacier-fed streams.
