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 researcher at CBD (2.9.2015)
Dr. Tim Burton is a biologist with a broad interest in the causes and consequences of phenotypic variation.
Using experimental approaches in both the field and laboratory he has addressed a range of questions concerning how environmental conditions both in previous generations and in early life can generate phenotypic differences in physiology, behaviour and growth/reproduction.
At NTNU Tim will be collaborating with Prof Sigurd Einum to investigate, using the clonally reproducing crustacean Daphnia magna as an experimental model, how animals respond to changing patterns of environmental variability in both the short and long term.

Successful Wild Animal Genomics Meeting in Selbu (20.08.2015)
A workshop on the use of genomics techniques in natural populations was held June 23rd-25th in Selbu, a small village 40 km east of Trondheim, Norway. The workshop was organized by the CBD-members Arild Husby and Henrik Jensen and was funded by grants from the Norwegian Research Council and CBD. 29 researchers from 9 countries across Europe and N-America attended the workshop. Participants ranged from PhD-students to well established, and internationally leading researchers within the field. The shared interest of all participants and the main focus of the discussion was how we best can make use of the recent development of genomics techniques to answer key questions in ecology, genetics, conservation and evolution of natural populations. There was large diversity in the topics of the talks. Fortunately, most participants mainly presented work in progress,. Combined with the informal atmosphere at the workshop this resulted in many fruitful discussions. Hopefully, this will contribute to the role that use of genomics techniques will play in increasing our understanding of fundamental processes in natural populations.

PhD position in Evolutionary Ecology (14.8.2015)
At the Faculty of Natural Sciences and Technology, Department of Biology there is a PhD position available. The position is financed by The Norwegian Research Council and has a special responsibility for the project “Evolutionary Responses to Variable and Unpredictable Environments”.

Award to CBD-members (03.8.2015)
The CBD-members Steinar Engen, Russell Lande and Bernt-Erik Sæther were selected by the Wildlife Society as recipients of the 2015 Wildlife Publications Award for the paper "Evolutionary consequences of non-selective harvesting in density-dependent populations" published in the American Naturalist 184 (6): 714-726 in 2014. The Award will be presented during the Wildlife Society 22nd Annual Conference in Winnipeg, Canada in October 2015.
Svalbard expedition with the sailboat Sillage (03.07.2015)
A one month expedition around Spitsbergen has just started, with the aim to collect samples and data for Mathilde Le Moullec's PhD and a new CBD project financed by Svalbards Environmental Protection Fund (B.B. Hansen). The goal of the latter project is to document current abundances and historical distributions of the wild Svalbard reindeer and link this with meta-population genetics. The study system represents a unique opportunity to examine effects of bottlenecks due to excessive harvest and local extinctions, recolonisation, as well as climate-related migration barriers. Thus, current and ancient DNA (from old bones and antlers) will be collected in addition to distance sampling data for estimation of spatial densities. Mathilde will also collect plant samples for dendrochronological measures of past vegetation growth in relation to climate and grazing pressure. Other expedition members are Morgan Bender (field assistant) and the crew, Marie and Christophe. First stop is Sørkapp Land on Friday 3rd July, next stops will be on Edgeøya and Barentsøya.
Master student from Finland visiting CBD (10.06.2015)
Emma Marjakangas is a Master's student from Finland staying here at CBD for 3 months as an Erasmus intern. She is finishing up with her Master's degree and will graduate soon from University of Jyväskylä. During her internship she will analyze fungal community datasets in order to predict the species richness and population sizes of wood-inhabiting fungi in a Finnish boreal forest.
Video presentation of recent Oikos paper (10.04.2015)
A short video presentation of a recent paper from the REINCLIM project on Svalbard reindeer can be watched here. The paper by Aline M. Lee and coworkers is published in Oikos with the following title: "An integrated population model for a long-lived ungulate: more efficient data use with Bayesian methods".
