• 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. (Elsevier, 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 ...

• Preconcentration and speciation analysis of mercury : 3D printed metal scavenger-based solid-phase extraction followed by analysis with inductively coupled plasma mass spectrometry 

  Kulomäki, Suvi; Lahtinen, Elmeri; Perämäki, Siiri; Väisänen, Ari (Elsevier BV, 2022)

  A selective method for preconcentration and determination of methylmercury (MeHg) and inorganic mercury (iHg) in natural water samples at the ng L−1 level has been developed. The method involves adsorption of Hg species ...

• UV-B Exposure Causes DNA Damage and Changes in Protein Expression in Northern Pike (Esox lucius) Posthatched Embryos 

  Vehniäinen, Eeva-Riikka; Vähäkangas, Kirsi; Oikari, Aimo (John Wiley & Sons, 2012)

  The ongoing anthropogenically caused ozone depletion and climate change has increased the amount of biologically harmful UV-B radiation, which is detrimental to fish in embryonal stages. The effects of UV-B radiation ...

• Fluence rate or cumulative dose? : Vulnerability of larval northern pike (Esox lucius) to ultraviolet radiation 

  Vehniäinen, Eeva-Riikka; Häkkinen, Jani; Oikari, Aimo (Wiley-Blackwell Publishing, Inc.; American Society for Photobiology, 2007)

  Newly hatched larvae of northern pike were exposed in the laboratory to four fluence rates of ultraviolet radiation (UVR; 290–400 nm) over three different time periods, resulting in total doses ranging from 3.0 ± 0.2 to ...

• Parasite transmission in aquatic ecosystems under temperature change : effects of host activity and elimination of parasite larvae by filter-feeders 

  Gopko, Misha; Mironova, Ekaterina; Pasternak, Anna; Mikheev, Victor; Taskinen, Jouni (Wiley-Blackwell, 2020)

  A moderate raise in temperature was suggested to enhance the impact of parasites on aquatic ecosystems. Under higher temperatures, poikilothermic animals (e.g. fish) increase their activity, which can result in a more ...
