Many lakes in the northern hemisphere are browning due to increasing concentrations of terrestrial dissolved organic carbon (DOC). The consequences of lake browning to littoral invertebrates, however, are not fully understood. We analyzed community structure and fatty acid (FA) profiles of littoral invertebrates in humic (DOC-rich) and clear-water lakes in Eastern Finland. We found higher abundance of chironomids (Diptera: Chironomidae) in humic compared to clear-water lakes, whereas stoneflies (Plecoptera) and mayflies (Ephemeroptera: Baetidae) were more abundant in clear-water lakes. Taxon explained 65% of the differences in the FA composition of littoral invertebrates. However, the proportion and content of polyunsaturated FAs of several taxa were significantly higher in clear-water lakes compared to humic lakes. Our results reveal differences in both community structure and nutritional quality of littoral invertebrates for fish between humic and clear-water lakes.

Periphyton as a key diet source of essential fatty acids for macroinvertebrates across a nutrient and dissolved organic carbon gradient in boreal lakes
Vesterinen, Jussi; Strandberg, Ursula; Taipale, Sami J.; Kainz, Martin J.; Kankaala, Paula (Wiley; Association for the Sciences of Limnology and Oceanography, 2022)We studied how physiologically important long-chain polyunsaturated fatty acids (PUFA) in benthic macroinvertebrates (Asellus aquaticus, Chironomidae, and Oligochaeta) were related to those in periphyton and terrestrial ... -
Herbivorous cladoceran essential fatty acid and cholesterol content across a phosphorous and DOC gradients of boreal lakes : Importance of diet selection
Keva, Ossi; Litmanen, Jaakko J.; Kahilainen, Kimmo K.; Strandberg, Ursula; Kiljunen, Mikko; Hämäläinen, Heikki; Taipale, Sami J. (Wiley, 2023)1. Eutrophication has been shown to increase production of nutritionally low-quality cyanobacteria and decrease the long-chain polyunsaturated fatty acid (PUFA) content of seston. Contrarily, lake browning inhibits ... -
Poor nutritional quality of primary producers and zooplankton driven by eutrophication is mitigated at upper trophic levels
Taipale, Sami Johan; Ventelä, Anne‐Mari; Litmanen, Jaakko; Anttila, Lauri (John Wiley & Sons, 2022)Eutrophication and rising water temperature in freshwaters may increase the total production of a lake while simultaneously reducing the nutritional quality of food web components. We evaluated how cyanobacteria blooms, ... -
Environmental drivers alter PUFA content in littoral macroinvertebrate assemblages via changes in richness and abundance
Strandberg, Ursula; Arhonditsis, George; Kesti, Petri; Vesterinen, Jussi; Vesamäki, Jussi S.; Taipale, Sami J.; Kankaala, Paula (Springer, 2023)Shallow littoral areas in lakes are productive and highly diverse ecotonal zones, providing habitats for both invertebrate and vertebrate species. We developed a Bayesian modeling framework to elucidate the relationships ... -
Water quality shapes the community structure of zoobenthos in rivers but only has a minor effect on the fatty acid composition of zoobenthos and salmonids
Kesti, Petri; Strandberg, Ursula; Taipale, Sami; Hiltunen, Minna; Vesterinen, Jussi; Vainikka, Anssi; Kankaala, Paula (John Wiley & Sons, 2024)Many river ecosystems in the boreal zone have faced remarkable changes due to intensive human activities, including land-use changes in the catchments and channelization. Recently, restoration efforts have increased, hoping ...
