Food webs in the era of molecular revolution – Like resolving the Gordian knot with a tricorder
(Turun yliopistoAnnales Universitatis Turkuensis A II 307, 2015-12-04)
Living nature consists of countless organisms, which are classified into millions of species. These species interact in many ways; for example predators when foraging on their prey, insect larvae consuming plants, and ...
RNA Silencing and its Inhibition in transgenic Tobacco Plants
(Turun yliopistoAnnales Universitatis Turkuensis AII 219, 2007-12-15)
Trophic cascades in boreal landscapes: top predator protection on tree seedlings and forest grouse
(Turun yliopistoAnnales Universitatis Turkuensis A II 310, 2016-01-29)
Changes in the abundance of top predators have brought about notable, cascading effects in ecosystems around the world. In this thesis, I examined several potential trophic cascades in boreal ecosystems, and their separate ...
Photodamage to Oxygen Evolving Complex - An Initial Event in Photoinhibition of Photosystem II.
(Turun yliopistoAnnales Universitatis Turkuensis AII 212, 2007-09-17)
Photosystem II (PSII) of oxygenic photosynthesis is susceptible to photoinhibition. Photoinhibition is defined as light induced damage resulting in turnover of the D1 protein subunit of the reaction center of PSII. Both ...
Role of nutrients in regulation of the phytoplankton community in the Archipelago Sea, northern Baltic Sea
(Turun yliopistoAnnales Universitatis Turkuensis A II 239, 2009-08-07)
Determinants of Polylepis (Rosaceae) Forest Distribution and Treeline Formation in the High Andes
(Turun yliopistoAnnales Universitatis Turkuensis A II 288, 2014-05-23)
High elevation treelines are formed under common temperature conditions worldwide, but the functional mechanisms that ultimately constrain tree growth are poorly known. In addition to environmental constraints, the ...
Evolutionary Ecology of Mountain Birch in Subarctic Stress Gradients: Interplay of Biotic and Abiotic Factors in Plant-Plant Interactions and Evolutionary Processes
(Turun yliopistoAnnales Universitatis Turkuensis A II 233, 2009-02-28)
In nature, variation for example in herbivory, wind exposure, moisture and pollution impact often creates variation in physiological stress and plant productivity. This variation is seldom clear-cut, but rather results in ...
Evolutionary History and Taxonomy of Neotropical Marattioid Ferns: Studies of an Ancient Lineage of Plants
(Turun yliopistoAnnales Universitatis Turkuensis AII 216, 2007-11-24)
Structural complexity and social cohesion in gregarious animals: from conflict to cooperation
(Turun yliopistoAnnales Universitatis Turkuensis A II 327, 2016-10-28)
A social lifestyle is abundant in nature. The social interactions between animals form the basis for complex, highly dynamic structures and may determine group-level processes such as group cohesion. Social behavior is ...
Establishment and Enhancement of Mu in vitro DNA Transposition Applications: Novel Procedures and New Tools
(Turun yliopistoAnnales Universitatis Turkuensis A II 324, 2016-10-21)
Transposable elements, or transposons, are DNA segments that have the ability to move from one location on the genome to another. They have been widely utilized as molecular tools in the study of prokaryotes, plants, ...
