Environmental and biological factors are joint drivers of mercury biomagnification in subarctic lake food webs along a climate and productivity gradient
Kozak, Natalia; Ahonen, Salla A.; Keva, Ossi; Østbye, Kjartan; Taipale, Sami J.; Hayden, Brian; Kahilainen, Kimmo K. (Peer reviewed; Journal article, 2021)Subarctic lakes are getting warmer and more productive due to the joint effects of climate change and intensive land-use practices (e.g. forest clear-cutting and peatland ditching), processes that potentially increase ... -
Mercury and amino acid content relations in northern pike (Esox lucius) in subarctic lakes along a climate-productivity gradient
Kozak, Natalia; Kahilainen, Kimmo Kalevi; Pakkanen, Hannu K.; Hayden, Brian; Østbye, Kjartan; Taipale, Sami J. (Peer reviewed; Journal article, 2023)Mercury is a highly toxic element for consumers, but its relation to amino acids and physiology of wild fish is not well known. The main aim of this study was to evaluate how total mercury content (THg) of northern pike ... -
Seasonal changes in European whitefish muscle and invertebrate prey fatty acid composition in a subarctic lake
Keva, Ossi; Tang, Patrik; Käkelä, Reijo; Hayden, Brian; Taipale, Sami J.; Harrod, Chris; Kahilainen, Kimmo Kalevi (Peer reviewed; Journal article, 2019)Ambient light and temperature show extreme seasonal variation in subarctic lakes due to the midnight sun period in summer and cold polar night period in winter. These changes have clear impacts on fish feeding and reproduction ...
