The vision behind the Centre for Biodiversity Dynamics at NTNU is to develop an interdisciplinary centre for research into changes in time and space of biological diversity at different organismal levels.
CBD focuses on three primary research areas, in which we believe it is important to increase knowledge for the sustainable conservation of biodiversity in a changing world.
CBD includes researchers primarily from the following institutions:
• Department of Biology, NTNU
• NTNU University Museum
• Department of Mathematical Sciences, NTNU
• Norwegian Institute for Nature Research (NINA)
New postdoc at CBD
Dr. Yimen Araya-Ajoy has joined CBD as a postdoc of the behaviour and evolution section in the department of biology. Yimen is an evolutionary ecologist with a background in behavioral ecology and quantitative genetics. He has worked with the social structure and acoustic communication of Ocellated Antbirds in Costa Rica and the behavior and mating strategies of Great Tits in Germany. At the NTNU, Yimen will be collaborating with Prof. Jon Wright on the project “'Life History Evolution in a Changing World: The Adaptive Alignment of Pace-of-Life Syndromes'” to find out how environmental variation shapes the life histories of House Sparrows.
New Ph.D Student
Dilan Saatoğlu has joined CBD as a Ph.D student and will work on a project which aims to understand ecological and evolutionary dynamics in time and space in natural populations supervised by Assoc. Prof. Dr. Henrik Jensen. In 2015 Dilan completed her MSc in population genetics and defended her master thesis entitled "Genetic Diversity of Gazelles (Gazella marica and Gazella gazella) in Southeast Turkey: with A Special Emphasis on Ongoing Conservation Studies of Gazella marica in Turkey". Her MSc-project was done in collaboration with Ministry of Forestry of Turkey and The Scientific and Technological Research Council of Turkey (Tübitak) in Middle East Technical University.
Postdoc Joost Raeyermaekers
Dr. Joost Raeymaekers has joined CBD as a postdoc of the Freshwater Ecology group. Joost is an evolutionary ecologist with a background in population genetics, adaptation and ecological speciation, eco-evolutionary dynamics, and host-parasite interactions in stickleback fishes, East-African cichlids, Darwin’s finches and water fleas. At NTNU Joost will be collaborating with Prof. Sigurd Einum on the project “Eco-evolutionary dynamics of thermal reaction norms” to find out how genetic variation and temperature influence the population dynamics of water fleas.
The steering board of NORDFORSK has decided to fund the project " Warming up for warming Arctic – adaptation and management of Rangifer in Changing Arctic". CBD is looking forward to be one of the Nordic research institutions involved in developing strategies for a sustainable management of semi-domestic reindeer in a new climate.
Postdoctoral position in evolutionary genomics
A two-year postdoctoral position in evolutionary genomics funded by a grant from the Norwegian Research Council to Assistant Professor Arild Husby is available at the Centre for Biodiversity Dynamics (CBD), Department of Biology, NTNU, Norway. Read more about the position here >>
PhD position available

PhD position in Quantitative Ecology available (13.11.2015)
The PhD candidate will work on quantitatively oriented research questions in ecology, often involving estimating and predicting how different environmental drivers or various kinds of human activity affect population dynamics and/or community dynamics. A full description of the position is available here >>
Erik Blystad Solbu - Defence of thesis 12 November 2015 (6.11.2015)
Erik Blystad Solbu has submitted his thesis entitled: «Modelling and statistical analysis of demographic and environmental changes in populations and communities»
in partial fulfillment of the requirements for the degree of PhD in Mathematical Sciences at the Department of Mathematical Sciences, NTNU. More information here>>
CBD welcomes PhD student Thomas Haaland (03.11.2015)
Thomas Haaland has joined CBD as a Ph.D student on dr. Irja Ratikainen’s new project “Evolutionary responses to variable and unpredictable environments: Conditions, interactions and consequences”. Thomas completed his MSc in Biology with Irja and Prof. Jonathan Wright in August, entitled “A general stochastic dynamic model of the differential allocation hypothesis”, and will continue working on stochastic dynamic models as well as individual-based simulation models for his Ph.D. He will be looking at well known adaptations to variability within individual lifetimes such as insurance, asset-protection and variance-sensitivity, and how these change when maximizing fitness over evolutionary time if environmental conditions vary across generations.
