Effects of photoperiod on life-history and thermal stress resistance traits across populations of Drosophila subobscura
Nasiri Moghadam, Neda; Novicic, Zorana Kurbalija; Pertoldi, Cino; Kristensen, Torsten N.; Bahrndorff, Simon (John Wiley & Sons Ltd., 2019)Introduction Organisms use environmental cues to match their phenotype with the future availability of resources and environmental conditions. Changes in the magnitude and frequency of environmental cues such as photoperiod ... -
Responses to Developmental Temperature Fluctuation in Life History Traits of Five Drosophila Species (Diptera: Drosophilidae) from Different Thermal Niches
Manenti, Tommaso; Kjærsgaard, Anders; Munk Schou, Toke; Pertoldi, Cino; Moghadam, Neda N.; Loeschcke, Volker (MDPI AG, 2021)Temperature has profound effects on biochemical processes as suggested by the extensive variation in performance of organisms across temperatures. Nonetheless, the use of fluctuating temperature (FT) regimes in laboratory ... -
Broad thermal tolerance is negatively correlated with virulence in an opportunistic bacterial pathogen
Ashrafi, Roghaieh; Bruneaux, Matthieu; Sundberg, Lotta-Riina; Pulkkinen, Katja; Valkonen, Janne; Ketola, Tarmo (Wiley-Blackwell Publishing, Inc., 2018)Predicting the effects of global increase in temperatures on disease virulence is challenging, especially for environmental opportunistic bacteria, because pathogen fitness may be differentially affected by temperature ... -
Heat hardening capacity in Drosophila melanogaster is life stage-specific and juveniles show the highest plasticity
Nasiri Moghadam, Neda; Ketola, Tarmo; Pertoldi, Cino; Bahrndorff, Simon; Kristensen, Torsten N. (The Royal Society Publishing, 2019)Variations in stress resistance and adaptive plastic responses during ontogeny have rarely been addressed, despite the possibility that differences between life stages can affect species' range margins and thermal tolerance. ... -
Impacts of reduced Lepidurus arcticus availability on brown trout life history traits in a mountain reservoir
Lakka, Hanna-Kaisa; Eloranta, Antti P.; Hesthagen, Trygve; Saksgård, Randi; Power, Michael (Springer, 2020)Lepidurus arcticus (the Arctic tadpole shrimp) is a vulnerable keystone species in Arctic and alpine water bodies where its occurrence and population size may influence the viability and life history traits of resident ...
