Landscape determinants of lake benthic and pelagic primary production

Global change affects gross primary production (GPP) in benthic and pelagic habitats of northern lakes by influencing catchment characteristics and lake water biogeochemistry. However, how changes in key environmental drivers manifest and impact total (i.e., benthic + pelagic) GPP and the partitioning of total GPP between habitats, here represented by the benthic share (autotrophic structuring) is unclear. This dataset presentes compiled data on summer gross primary productivity (GPP) in benthic and pelagic habitats sampled in situ between 2005-2017, together with water chemistry, from 26 shallow lakes (maximum 3.7-15.8 m deep) from three different sites in northern Sweden, located in the Arctic (Norrbotten), subarctic (Jämtland) and boreal (Västerbotten) biomes. The three study regions have variable elevation gradients and vegetation cover. The study lakes cover a wide range of DOC (1.5-16.3 mg·L-1) and accompanied water physico-chemistry.
Using this dataset, we investigate how catchme...
