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)
Report from The workshop on “Mitigation measures of human induced impacts on marine ecosystems (6.10.2015)
The workshop on “Mitigation measures of human induced impacts on marine ecosystems” organized by the CBD-members Olivia Langhamer and Petra Rodewald was held September 16th at IBI. It was a rather small, but very interesting and constructive workshop where 15 researchers from different institutions in Norway (NTNU with IBI and Ind. Ecology, NINA, NIVA), from KVA in Sweden and from Melbourne University in Australia gathered. Read more about the Workshop >>

CBD at the Arctic Ungulate Conference (7.9.2015)
CBD was well represented at the 17th Arctic Ungulate Conference in Røros, Norway, 17-21 August. The subject for the conference was "The past, the present, and the future". CBD contributed substantially through several talks and posters, which included presentations of work on Svalbard reindeer by Larissa Beumer, Bart Peeters and Mathilde Le Moullec.
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.
Thomas Haaland defends his MSc thesis (18.8.2015)
Monday August 24th Thomas Haaland will defend his MSc thesis and we will follow the new practice. He will therefore present his thesis at 12.00 in the CBD room, and you are all welcome to his talk: “A General Stochastic Dynamic Model of the Differential Allocation Hypothesis”.
Elida Aarstad Skøien defens her MSc thesis (18.08.2015)
On thursday August 27th Elida Aarstad Skøien will defend her MSc Thesis (from the LUR programme) in CBD room at 9:00. «Causes and Consequences of Breeding Synchrony in the Snow Bunting (Plectrophenax nivalis)".
Supervisors are Hansen, Fossøy, Ringsby.
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”. Read more about the position here >>.
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.
