Insights from unseen individuals – using non-invasive approaches to study population biology of white-tailed deer in Finland
(Turun yliopisto, 2020-04-24)
Density, adult sex ratio and fecundity are biologically important population parameters, whose estimation is also essential for wildlife management and conservation. These parameters describe population viability and predict ...
Tolerance of baltic sea rocky littoral communities to climate change
(Turun yliopisto, 2018-06-01)
Climate change is challenging marine ecosystems worldwide, severely straining
the tolerance of marine species and likely leading to distributional shifts. In the
brackish-water Baltic Sea, there is a strong salinity ...
Plant remains in archaeology : a multidisciplinary approach to cultivation,consumption, trade and migration of economic plants in Southern Finland AD 1000−1900
(Turun yliopisto, 2019-03-16)
Plant remains are derived from archaeological contexts and therefore they provide an interesting source material for investigating the role of economic plants and environments in the past. Plant remains can reflect past ...
Linking community dynamics with ecosystem processes in tundra Conceptual, empirical and methodological approaches
(Turun yliopisto, 2020-02-28)
In low-productive tundra systems, both small and large herbivores exert strong control over plant biomass and community composition. They may also modulate ecosystem process rates, including availability and cycling of ...
Population dynamics and evolutionary genetics of life history variation in Atlantic salmon
(Turun yliopisto, 2019-06-01)
Knowledge about variation in abundance and life-history traits is necessary to manage exploited populations. Atlantic salmon, Salmo salar, has high cultural, ecological and economic importance, supporting subsistence, ...
Food hoarding of an avian predator under food limitation and climate change
(Turun yliopisto, 2020-10-23)
Hoarding behaviour (storing food for later use) has evolved to reduce the risk of starvation when resources are scarce. In this thesis, I studied the food-hoarding behaviour of Eurasian pygmy owls (Glaucidium passerinum) ...
Evolutionary history of ferns and the use of ferns and lycophytes in ecological studies
(Turun yliopisto, 2019-05-20)
Tropical areas represent the region with the highest diversity in the world. In plants, one major radiation having this high diversity is ferns, the sister lineage of seed plants, which, together with lycophytes, another ...
Thermal relations and molecular measures in salmonidae gene expression
(Turun yliopisto, 2019-06-27)
Arctic, boreal and temperate latitudes are characterised by conspicuous shifts in photoperiod and temperature, which restricts ecosystem productivity and compels resident taxa to anticipate and coordinate physiological ...
A comparative study of parasitism in insects : why some Odonata species have parasites and others do not?
(Turun yliopisto, 2018-08-31)
Parasites are one of the most diverse groups of animals, capable of infecting virtually all other organisms on the planet. They are a strong evolutionary force, influencing genetic diversity and thereby affecting individuals, ...
Local extinction risk and community structure of odonata populations in Fennoscandia
(Turun yliopisto, 2020-03-06)
A key need in conservation biology is to identify the ecological traits of a species that make it vulnerable. This thesis focuses on population traits and extinction risk of dragonflies and damselflies (order Odonata) in ...
