Group leader: Päivi Onkamo (University of Turku)
The SUGRIGE project aims at getting a whole-genome picture of ancient and contemporary Finns and Finno-Ugrians. We sequence ancient human remains from the regions where Finno-Ugrians live or used to live, in collaboration with Max Planck Institute for the Science of human history, Jena.

Group leader: Jarkko Salojärvi 
We study evolution; speciation, adaptation and host-microbe interactions in plants using statistical modeling and different -omics data sources.

C

Canopy Spectral Ecology and Ecophysiology
Group leader: T Matthew Robson
CanSEE studies how plants respond to changes in spectral composition, how these cues are processed and received by leaves and by the whole plant. We place this research in context, considering how the spectral irradiance perceived by plants changes depending on their environment.

Cell Wall and Epidermal Integrity
Group Leader: Cezary Waszczak
Toward understanding epidermal integrity and extrastomatal control of transpiration.
According to the classical understanding of plant gas exchange, the uncontrolled loss of water from plant aerial organs is restricted by epidermis that is covered by a hydrophobic layer called cuticle. Because of these properties, the majority of plant gas exchange occurs through stomata. Consequently, composition of cuticle and fast guard cell signaling are thought to be the major factors limiting transpiration. We are expanding this classical model with the use of forward genetic approaches. Our results indicate that modifications of cell wall structure and composition leading to e.g. loss of cell adhesion, can affect plant gas exchange independently of cuticle synthesis and guard cell function.

Centre of Excellence in Tree Biology – TreeBio
Group leader: Ykä Helariutta
Unraveling the carbon sequestration in trees and its potential improvement to mitigate climate change requires knowledge from and interaction between many branches of science and society. Understanding of the carbon sink effect in trees at a molecular level is still relatively superficial compared to many other aspects of this complex problem. The Principal Investigators of TreeBio CoE constitute a long tradition and scientific continuum of the studies on the physiology and genetic regulation of CO2 uptake through stomata, long distance transport and radial growth in trees. In order to approach the tree traits significant for the carbon sink effect and to integrate our research on the role of trees in forest vegetation as key carbon storage, we are consolidating here our approach by expanding our consortium to a multidisciplinary team representing a broad base in tree genetics, physiology and computational modelling of whole tree physiology.

Crop Light
Group leader: Saijaliisa Kangasjärvi
Resilience, flavor tailoring and indoor cultivation
We study how light affects the growth, chemical composition and ageing of plants. Many stress-induced phytochemicals affect the resilience, color, flavor and nutritional value of vegetables. Our aim is to apply the basic knowledge of plant photobiology for improved indoor cultivation and post-harvest quality of vegetables.

E

Eco-Evolutionary Dynamics
Group leader: Frédéric Guillaume
How do species adapt to changing environments? How does genetic variation map onto phenotypic variation, and ultimately fitness? We address these questions with a mix of theoretical (modelling) and experimental approaches. We use experimental evolution in the lab with the beetle Tribolium castaneum to unravel the evolutionary importance of genetic and phenotypic changes over time utilizing genomics and quantitative genetics data. With models we seek to understand how evolutionary constraints affect the pace of adaptation to fluctuating environments in different species with different genetic architectures and different life-history strategies.

Ecology and Evolution of Interactions
Group leader: Johanna Mappes
Our lab has long-standing interests to understand the behavioural and genetic processes that underscore variation in animal interactions. Our main line of questioning investigates the evolution of polymorphism within populations and divergence between populations. Experimental studies in the lab and field are our speciality.

Emotion science
Group leader: Sonja Koski
We are developing thermographic techniques to measure animal emotions and researching factors that affecting human skills in detecting those emotions. We are collaborating with Helsinki Zoo, Korkeasaari

Environmental and Ecological Statistics Group
Group leader: Jarno Vanhatalo
Environmental sciences includes a broad range of scientific fields studying the environment and solutions to environmental challenges. Ecology studies the distribution and abundance of species, and their interactions with other species and the environment. Statistical inference and uncertainty estimation are essential for both fields to ensure that appropriate conclusions and decisions can be reached from experiments and observations.

Evolution, Conservation, and Genomics
Group leader: Craig Primmer
Life history is the nexus of biology, because various biological questions ultimately revolve around the causes and consequences of variation in reproduction and survival, i.e. fitness. The fitness of male vs female life histories, however, do not always align, and hence life history traits may be...

Evolution, Sociality and Behaviour
Our group is a consortium of multiple principal investigators working around the common theme of sociality, behaviour and evolution. We studie in­ter­ac­tions cre­at­ing evol­u­tion­ary pro­cesses and pat­terns.

G

Global Change and Conservation
Group leader: Mar Cabeza
Inter­disciplinary ap­proaches for applied con­ser­va­tion

I

Integrative Evolutionary Biology
Group leader: Claudius Kratochwil
The Integrative Evolutionary Biology (IEB) group is dedicated to understanding the intricacies of phenotypic diversity. Our primary research centers on the coloration of tropical fish species. Using them as a model, we explore the genomic, developmental, and cellular mechanisms behind their remarkable diversity and the evolutionary forces that have shaped it.

L

Life-history evolution
Group leader: Marjo Saastamoinen
Life-History Evolution research group focuses on understanding how organisms cope with environmental variation in nature, such as habitat fragmentation or environmental stress. Our main study system is the Glanville fritillary butterfly (Melitaea cinxia) metapopulation in the Åland Islands.
