• Inbreeding does not alter the response to an experimental heat wave in a freshwater snail 

  Leicht, Katja; Jokela, Jukka; Seppälä, Otto (Public Library of Science, 2019)

  Global climate change affects natural populations of many species by increasing the average temperature and the frequency of extreme weather events (e.g. summer heat waves). The ability of organisms to cope with these ...

• Direct and transgenerational effects of an experimental heatwave on early life stages in a freshwater snail 

  Leicht, Katja; Seppälä, Otto (Wiley-Blackwell Publishing Ltd., 2019)

  Global climate change imposes a serious threat to natural populations of many species. Estimates of the effects of climate change‐mediated environmental stresses are, however, often based only on their direct effects on ...

• Effects of incubation temperature and maternal phenotype on Baltic herring (Clupea harengus membras) eggs and larvae : An experimental study 

  Mäkinen, Katja; Rajasilta, Marjut; Ruuskanen, Suvi; Karpela, Tiia; Lauerma, Aarne O.; Sahlstén, Johannes (Canadian Science Publishing, 2023)

  Temperature modifies the reproductive success of fish, yet, in many species, we lack the information on its role in the early development. In this study, the effect of temperature on the relation between maternal traits ...

• Potential for adaptation to climate change: family-level variation in fitness-related traits and their responses to heat waves in a snail population 

  Leicht, Katja; Seppälä, Katri; Seppälä, Otto (BioMed Central, 2017)

  On-going global climate change poses a serious threat for natural populations unless they are able to evolutionarily adapt to changing environmental conditions (e.g. increasing average temperatures, occurrence of extreme ...

• 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 ...
