Here, the potential of a combination of different spectroscopic ... -
Conservation and regulation of key photoperiod regulators in the Pooideae subfamily of grasses
Young, Darshan Anthony (Master thesis, 2018)Plants have adapted to seasonal constraints of the temperate environment by exploiting annual fluctuations in day length. Well timed flowering is essential to maximize reproductive output in temperate regions with short ... -
Cytisus scoparius : a genetic and historical analysis of introduction history in Norway
Furevik, Beate Beatriz (Master thesis, 2017-01-02)Cytisus scoparius is an invasive species threatening the local flora where the shrub is introduced. Studies show that the shrub spreads rapidly and has damaging effects in areas where the plant is considered invasive. ... -
Discrimination of grass pollen of different species by FTIR spectroscopy of individual pollen grains
Diehn, Sabrina; Zimmermann, Boris; Tafintseva, Valeria; Bağcıoğlu, Murat; Kohler, Achim; Ohlson, Mikael; Fjellheim, Siri; Kneipp, Janina (Peer reviewed; Journal article, 2020) -
Ecological effects of Cytisus scoparius invasion : a native or alien species?
Brandes, Ursula (PhD Thesis;2019:31, Doctoral thesis, 2019)The number of alien invasive species is continually increasing, threatening the environment and economy and their management is challenging. For cases of cryptic invasions, it is not even known if a species is native or ... -

Evolution of adaptations to temperate climate in the grass subfamily Pooideae
Schubert, Marian (PhD Thesis;2016:89, Doctoral thesis, 2016)Temperate biomes are characterized by strong temperature and photoperiod seasonality and frequently occurring frost. Temperate plants have evolved to overcome challenges like cold stress, prolonged winters and short ... -
