• Rehabilitation of two northern river lamprey (Lampetra fluviatilis) populations impacted by various anthropogenic pressures : lessons learnt in the past three decades 

  Aronsuu, Kimmo; Vikström, Risto; Marjomäki, Timo J.; Wennman, Kim; Pakkala, Jukka; Mäenpää, Eero; Tuohino, Jukka; Sarell, Juha; Ojutkangas, Esa (University of Jyväskylä, 2019)

  The pioneering work done during the past three decades in the regulated Rivers Perhonjoki and Kalajoki, Finland, to study and rehabilitate river lamprey populations is presented. The effects of various anthropogenic ...

• Migratory behaviour and holding habitats of adult river lampreys (Lampetra fluviatilis) in two Finnish rivers 

  Aronsuu, Kimmo; Marjomäki, Timo; Tuohino, Jukka; Wennman, Kim; Vikström, Risto; Ojutkangas, Esa (Boreal Environment Research Publishing Board, 2015)

  The effect of environmental factors on migratory activity of adult river lampreys entering the Kalajoki and Perhonjoki, rivers in Finland, for spawning was studied using correlation and regression analyses. Telemetric ...

• Biological responses of midge (Chironomus riparius) and lamprey (Lampetra fluviatilis) larvae in ecotoxicity assessment of PCDD/F-, PCB- and Hg-contaminated river sediments 

  Salmelin, Johanna; Karjalainen, Anna; Hämäläinen, Heikki; Leppänen, M. T.; Kiviranta, H.; Kukkonen, Jussi; Vuori, K. M. (Springer, 2016)

  We evaluated the utility of chironomid and lamprey larval responses in ecotoxicity assessment of polychlorinated dibenzo-p-dioxins, dibenzofurans (PCDD/F)-, polychlorinated biphenyls (PCB)- and mercury (Hg)-contaminated ...

• Are there plenty of fish in the sea? How life history traits affect the eco-evolutionary consequences of population oscillations 

  Ahti, Pauliina A.; Uusi-Heikkilä, Silva; Kuparinen, Anna (Elsevier, 2022)

  Understanding fish population oscillations is important for both fundamental population biology and for fisheries science. Much research has focused on the causes of population oscillations, but the eco-evolutionary ...

• Atlantic cod recovery from the Allee effect zone : contrasting ecological and evolutionary rescue 

  Kuparinen, Anna; Uusi-Heikkilä, Silva (Wiley-Blackwell, 2020)

  The ability of a population to recover from disturbances is fundamental for its persistence. Impaired population recovery might be associated with a demographic Allee effect. Immigration from adjacent populations could ...
