Phytoplankton group identification with chemotaxonomic biomarkers: In combination they do better

Autor: Peltomaa, E., Asikainen, H., Blomster, J., Pakkanen, H., Rigaud, C., Salmi, P., Taipale, S.

Chemotaxonomic biomarkers are needed to monitor and evaluate the nutritional quality of phytoplankton communities. The biomolecules produced by different phytoplankton species do not always follow genetic phylogeny. Therefore, we analyzed fatty acids

Temperature, phosphorus and species composition will all influence phytoplankton production and content of polyunsaturated fatty acids

Autor: Calderini, Marco L., Pääkkönen, Salli, Salmi, Pauliina, Peltomaa, Elina, Taipale, Sami J.

Temperature increases driven by climate change are expected to decrease the availability of polyunsaturated fatty acids in lakes worldwide. Nevertheless, a comprehensive understanding of the joint effects of lake trophic status, nutrient dynamics and

Metabolic plasticity of mixotrophic algae is key for their persistence in browning environments

Autor: Pauliina Salmi, Marco L. Calderini, Cyril Rigaud, Elina Peltomaa, Sami Taipale

Light availability is the main regulator of primary production, shaping photosynthetic communities and their production of ecologically important biomolecules. In freshwater ecosystems, increasing dissolved organic carbon concentrations, commonly kno

Poor nutritional quality of primary producers and zooplankton driven by eutrophication is mitigated at upper trophic levels

Autor: Sami Johan Taipale, Anne‐Mari Ventelä, Jaakko Litmanen, Lauri Anttila

Publikováno v: Ecology and Evolution. 12

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, driven by agricultural eutroph

Hydrogen isotopes (δ2H) of polyunsaturated fatty acids track bioconversion by zooplankton

Autor: Pilecky, Matthias, Kämmer, Samuel K., Mathieu‐Resuge, Margaux, Wassenaar, Leonard I., Taipale, Sami J., Martin‐Creuzburg, Dominik, Kainz, Martin J.

1. Organisms at the base of aquatic food webs synthesize essential nutrients, such as omega-3 polyunsaturated fatty acids (n-3 PUFA), which are transferred to consumers at higher trophic levels. Many consumers, requiring n-3 long-chain (LC) PUFA, suc

Periphyton as a key diet source of essential fatty acids for macroinvertebrates across a nutrient and dissolved organic carbon gradient in boreal lakes

Autor: Martin Kainz, Paula Kankaala, Ursula Strandberg, Jussi Vesterinen, Sami Taipale

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 organic matter (tree leaves),

Dark matters : contrasting responses of stream biofilm to browning and loss of riparian shading

Autor: Jussi Jyväsjärvi, Maria Rajakallio, Joanna Brüsecke, Kaisa‐Leena Huttunen, Ari Huusko, Timo Muotka, Sami J. Taipale

Concentrations of terrestrial-derived dissolved organic carbon (DOC) in freshwater ecosystems have increased consistently, causing freshwater browning. The mechanisms behind browning are complex, but in forestry-intensive regions browning is accelera

Lake browning impacts community structure and essential fatty acid content of littoral invertebrates in boreal lakes

Autor: Sami J. Taipale, Ursula Strandberg, Petri Kesti, Minna Hiltunen, Jussi Vesterinen, Paula Kankaala

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 s

Lowered nutritional quality of prey decrease the growth and biomolecule content of rainbow trout fry

Autor: Sami J. Taipale, Katja Pulkkinen, Ossi Keva, Martin J. Kainz, Hannu Nykänen

Diet quality is crucial for the development of offspring. Here, we examined how the nutritional quality of prey affects somatic growth and the lipid, carbohydrate, protein, amino acid, and polyunsaturated fatty acid content of rainbow trout (Oncorhyn
