Abundance and δ13C values of fatty acids in lacustrine surface sediments : Relationships with in-lake methane concentrations
Stötter, Tabea; Bastviken, David; Bodelier, Paul L.E.; van Hardenbroek, Maarten; Rinta, Päivi; Schilder, Johannes; Schubert, Carsten J.; Heiri, Oliver (Pergamon Press, 2018)Proxy-indicators in lake sediments provide the only approach by which the dynamics of in-lake methane cycling can be examined on multi-decadal to centennial time scales. This information is necessary to constrain how ... -
Responses of zooplankton to cane sugar additions to a small humic lake, Alinen Mustajärvi
Ewane, Basil (2010)The response to projected increase in dissolved organic carbon (DOC) loading to boreal lakes is being studied in lake Alinen Mustajärvi, a small humic lake in southern Finland, where labile DOC concentration has been ... -
Green sulphur bacteria as a component of the photosynthetic plankton community in small dimictic humic lakes with an anoxic hypolimnion
Karhunen, Jatta; Arvola, Lauri; Peura, Sari; Tiirola, Marja (Inter-Research, 2013)High bacteriochlorophyll (BChl) concentrations in the anoxic water layers of some humic lakes have indicated that green sulphur bacteria (GSB) may be ecologically significant. The abundance and spatial distribution of GSB ... -
CH4 oxidation in a boreal lake during the development of hypolimnetic hypoxia
Saarela, Taija; Rissanen, Antti J.; Ojala, Anne; Pumpanen, Jukka; Aalto, Sanni L.; Tiirola, Marja; Vesala, Timo; Jäntti, Helena (Birkhaeuser Science, 2020)Freshwater ecosystems represent a significant natural source of methane (CH4). CH4 produced through anaerobic decomposition of organic matter (OM) in lake sediment and water column can be either oxidized to carbon dioxide ... -
The reduction of selenium(IV) by boreal Pseudomonas sp. strain T5-6-I : Effects on selenium(IV) uptake in Brassica oleracea
Lusa, Merja; Help, Hanna; Honkanen, Ari-Pekka; Knuutinen, Jenna; Parkkonen, Joni; Kalasová, Dominika; Bomberg, Malin (Elsevier, 2019)Selenium (Se) is an essential micronutrient but toxic when taken in excessive amounts. Therefore, understanding the metabolic processes related to selenium uptake and bacteria-plant interactions coupled with selenium ...
