Regressive evolution of the pelvic complex in stickleback fishes: a study of convergent evolution
Klepaker, Tom; Østbye, Kjartan; Bell, Michael A. (Journal article; Peer reviewed, 2013)Background: Regressive evolution of the pelvic complex has been observed in populations of three of five stickleback genera, Gasterosteus, Pungitius, and Culaea, from young freshwater habitats (<18,000 years old). It has ... -
Spatio-temporal patterns in pelvic reduction in threespine stickleback (Gasterosteus aculeatus L.) in Lake Storvatnet
Klepaker, Tom; Østbye, Kjartan; Bernatchez, Louis; Vøllestad, L. Asbjørn (Peer reviewed; Journal article, 2012)Questions: The pelvic girdle with associated spines is an integrated anti-predator defence apparatus, and is assumed to protect against piscivores in the threespine stickleback. On the other hand, it might be costly to ... -
The temporal window of ecological adaptation in postglacial lakes: a comparison of head morphology, trophic position and habitat use in Norwegian threespine stickleback populations
Østbye, Kjartan; Harrod, Chris; Gregersen, Finn; Klepaker, Tom; Schulz, Michael; Schluter, Dolph; Vøllestad, Leif Asbjørn (Journal article; Peer reviewed, 2016)Background: Studying how trophic traits and niche use are related in natural populations is important in order to understand adaptation and specialization. Here, we des cribe trophic trait diversity in twenty-five ...
