As such, there is a need to understand how spatial controls may influence our interpretations of chironomid environment relationships. Here, we evaluated whether the distribution of chironomids followed spatial gradients, or were primarily controlled by environmental factors. Location: Eastern Canadian Arctic, Greenland, Iceland. Taxon: Non-biting midges (Chironomidae). Methods: We examined chironomid assemblages from 239 lakes in the western North Atlantic Arctic region (specifically from the Arctic Archipelago of Canada, two parts of west Greenland (the southwest and central west) and northwest Iceland). We used a combination of unconstrained ordination (Self Organizing Maps); a simple method with only one data matrix (community data), and constrained ordination (Redundancy Analysis); a canonical ordination with two datasets where we extracted structure of community related to environmental data. These methods allowed us to model chironomid assemblages across a large bioregional dimension and identify specific differences between regions that were defined by common taxa represented across all regions in high frequencies, as well as rare taxa distinctive to each region found in low frequencies. We then evaluated the relative importance of spatial processes versus local environmental factors. Results: We find that environmental controls explained the largest amount of variation in chironomid assemblages within each region, and that spatial controls are only significant when crossing between regions. Broad-scale biogeographic effects on chironomid distributions are reflected by the distinct differences among chironomid assemblages of Iceland, central-west Greenland, and eastern Canada, defined by the presence of certain common and low-frequency, rare taxa for each region. Environmental gradients, especially temperature, defined species distributions within each region, whereas spatial processes combine with environmental gradients in determining what mix of species characterizes each broad and geographically distinct island region in our study.

Lake sediments provide a continuous record for tracking and better understanding of human-environment interactions related to historical mining and metallurgical activities. Here, we present the analysis of pollen, diatom, cladoceran and chironomid record combined with Pb-21(0) dating, lithology and organic content of the sediments of Velka Richnava reservoir, located in an area intensively mined for polymetallic ores since the end of the 11th century (Banska Stiavnica region, Central Europe). Our aim was to reconstruct the changes in the vegetation cover in the catchment and aquatic biota initially caused by mining and after its cessation by changed management practices. Pollen analysis suggests an open landscape shaped by different land-use during and after the period of active mining toward increased grazing pressure and nutrie Kategória publikačnej činnosti ADC Číslo archívnej kópie 43524 Kategória ohlasu BLAKE, Johanna M. - BROWN, Jeb E. - FERGUSON, Christina L. - BIXBY, Rebecca J. - DELAY, Naomi T.
