• Population structure, life cycle, and trophic niche of the glacial relict amphipod, Gammaracanthus lacustris, in a large boreal lake 

  Salonen, Jouni K.; Hiltunen, Minna; Figueiredo, Kaisa; Paavilainen, Pinja; Sinisalo, Tuula; Strandberg, Ursula; Kankaala, Paula; Taskinen, Jouni (Wiley-Blackwell Publishing Ltd., 2019)

  Ecology of the glacial relict macrocrustacean Gammaracanthus lacustris, a rare inhabitant of deep Fennoscandian lakes, is poorly understood. We studied the life cycle and trophic position of this cold‐stenothermic amphipod ...

• Lifting the Vendace, Coregonus albula, on the Life Table : Survival, Growth and Reproduction in Different Life-Stages during Very High and Low Abundance Regimes 

  Marjomäki, Timo J.; Valkeajärvi, Pentti; Karjalainen, Juha (Finnish Zoological and Botanical Publishing Board, 2021)

  We analyzed the variability in vendace population parameters in the context of a life table. Parameters related to growth, fecundity and survival were estimated for post-recruitment (age > 1 growing season) life stages of ...

• Reproductive cycle, fecundity and growth of the freshwater mussel Unio tumidus (Bivalvia: Unionidae) from Lake Viinijärvi, Finland 

  Abdelsaleheen, Olfat; Taskinen, Jouni; Kortet, Raine (Oxford University Press (OUP), 2024)

  Freshwater mussels have a substantial role in aquatic ecosystem function and provide valuable ecosystem services, including water filtration, nutrient cycling, habitat creation and sediment stabilization. While they face ...

• Intraspecific divergence of sexual size dimorphism and reproductive strategies in a polytypic poison frog 

  Schlippe, Justicia Lia; Mayer, Martin; Lorioux-Chevalier, Ugo; Dittrich, Carolin; Rojas, Bibiana; Chouteau, Mathieu (Springer, 2023)

  Intraspecific variation in body size, both among populations and between sexes, is an important factor influencing life-history strategies. This variation might be the response to different environmental conditions, as ...

• Vendace populations on the life table : between-lake variation and the association between early life and mature survival and growth 

  Marjomäki, Timo J.; Auvinen, Heikki; Helminen, Harri; Huusko, Ari; Huuskonen, Hannu; Hyvärinen, Pekka; Jurvelius, Juha; Karels, Aarno; Sarvala, Jouko; Valkeajärvi, Pentti; Karjalainen, Juha (EDP Sciences, 2024)

  The vital rates related to reproduction and survival dictate the resistance and persistence of a population under perturbations. Freshwater fishes perform high levels of phenotypic plasticity thus these rates may differ ...
