Abstract. The spatial distribution of snow plays a vital role in sub-Arctic and Arctic climate, hydrology, ecology due to its fundamental influence on the water balance, thermal regimes, vegetation, carbon flux. However, is not well understood, therefore, it modeled, which can lead substantial uncertainties cover representations. To capture key hydro-ecological controls distribution, we carried...

Abstract Metacommunity models describe species occupancy frequency distribution (hereinafter ‘SOFD’). Our goal is to present how the differences in eight macroinvertebrate orders dispersal ability affect SOFD patterns. A total of 293 from were observed 14 eutrophic lakes southern Finland. Species ranged 1 14. About 30% (89 out 293) found only one lake, yielding a surprisingly high number rare s...
