• Adaptation and ecological speciation in seasonally varying environments at high latitudes : Drosophila virilis group 

  Hoikkala, Anneli; Poikela, Noora (Informa UK Limited, 2022)

  Living in high latitudes and altitudes sets specific requirements on species’ ability to forecast seasonal changes and to respond to them in an appropriate way. Adaptation into diverse environmental conditions can also ...

• Plasticity in Photoperiodism : Drosophila montana Females Have a Life-Long Ability to Switch From Reproduction to Diapause 

  Lankinen, Pekka; Kastally, Chedly; Hoikkala, Anneli (SAGE Publications, 2022)

  Photoperiodic reproductive diapause is an essential part of female life cycle in several insect species living on high latitudes, where overwintering in reproductive stage involves high risks for survival and progeny ...

• Direct and correlated responses to bi-directional selection on pre-adult development time in Drosophila montana 

  Kauranen, Hannele; Kinnunen, Johanna; Hopkins, David; Hoikkala, Anneli (Elsevier Ltd., 2019)

  Selection experiments offer an efficient way to study the evolvability of traits that play an important role in insects’ reproduction and/or survival and to trace correlations and trade-offs between them. We have exercised ...

• Selection for reproduction under short photoperiods changes diapause-associated traits and induces widespread genomic divergence 

  Kauranen, Hannele; Kinnunen, Johanna; Hiillos, Anna-Lotta; Lankinen, Pekka; Hopkins, David; Wiberg, R. Axel W; Ritchie, Michael G.; Hoikkala, Anneli (Company of Biologists, 2019)

  The incidence of reproductive diapause is a critical aspect of life history in overwintering insects from temperate regions. Much has been learned about the timing, physiology and genetics of diapause in a range of insects, ...

• Nanda-Hamner Curves Show Huge Latitudinal Variation but No Circadian Components in Drosophila Montana Photoperiodism 

  Lankinen, Pekka, Kastally, Chedly, Hoikkala, Anneli (SAGE Publications, 2021)

  Insect species with a wide distribution offer a great opportunity to trace latitudinal variation in the photoperiodic regulation of traits important in reproduction and stress tolerances. We measured this variation in the ...
