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)
Course in MODELLING ECOLOGY AND EVOLUTION
Otso Ovaskainen will be teaching a course in Modelling ecology and evolution, this spring in Trondheim. Applications for participation to Solveig Johnsen (firstname.lastname@example.org) by March 17th. Read more here >>
WORKSHOP: Ecological use of genomocs (11.02.2015)
In end of June there will be a workshop on the use of genomics in natural populations with many leading researchers from Europe and US attending. The aim is to bring together researchers working on a diverse set of questions, methods and study systems which all use genomic tools in their approach. As we aim to keep the meeting small, attendance is by invitation only. We are very pleased that Prof. Leif Andersson will be joining us at this meeting. Leif is one of the foremost experts in the world on the genomics of animal domestication and has recently also started to work on wild systems about which he will talk about in this meeting. See his web-site for more information about his research.
The workshop is organised by Arild Husby (University of Helsinki) and Henrik Jensen (CBD) and is funded by grants from the Norwegian Research Council (to AH) and CBD.
Visiting CBD: Prof. Subhash Lele, Department of Mathematical and Statistical Sciences, University of Alberta, Canada.
Subhash is a statistician interested and excited about the applications of statistics to biological sciences in general and ecology in particular. His current statistical methodological focus is on developing inferential and computational methods for general hierarchical models. These methods include data cloning, estimating functions, composite likelihood and other approximate likelihood methods. His ecological interests are occupancy models, movement models, resource selection studies and wildlife surveys that utilize expert opinion. He is also active in developing methods for population dynamics and population viability analysis. Website
SAB-meeting in Trondheim 20-21st January 2015 (27.1.2015)
The Scientific Advisory Board (SAB) visited CBD last week. In connection with their visit, PhD-candidates and post-docs at the centre presented their projects and recent work to the SAB and all CBD members.
CBD-IMPRS Workshop on Statistical Approaches to Multivariate Phenotypes, 11-16th January 2015 (16.1.2015)
This week PhD students and staff from the CBD visited The Max Planck Institute for Ornithology (MPIO) located in Seewiesen (not far from to Munchen). The workshop was initiated by Jonathan Wright and Niels Dingemanse. In addition to them, Alastair Wilson, Ned Dochtermann, Geir H. Bolstad and Yimen Araya-Ajoy contributed with insightful lectures on different aspect of how to understand and analyze multivariate data. This generated a lot of interesting discussions. During the workshop, time was also allocated to practical demonstration of different statistical approaches – including that the students used their newly acquired knowledge on their own data.
Post doc Nerea Abrego (14.1.2015)
Nerea Abrego defended her PhD at the University of the Basque Country (Spain), in December 2014. She studied how human-induced environmental changes affect wood-inhabiting fungal diversity and assembly processes at different spatial scales, and how these processes are related to functional traits and interaction networks. Currently, she collaborates with researchers from several European countries in a project which lies on disentangling the processes driving the composition of wood-inhabiting fungal communities in European beech forest reserves, as well as with researchers from the University of Jyväskylä (Finland) in a project which lies on assessing the impacts of forest management on poorly-known fungal species assemblages from boreal forests. During her postdoc in CBD, she aims to combine empirical, experimental and new modeling approaches for a better understanding of community dynamics more generally.

2nd conference of Norwegian Ecological Society Ecological Change, changing ecology (12.1.2015)
News on the NØF2015 Conference in Bergen in March!We have extended the abstract deadline until the 30th January - some of us haven't managed to submit our abstracts yet, so we guessed that maybe some more of you plan to as well Click below to visit the Conference homepage and submit your abstract: http://nof2015.uib.no/
Dr. Katja Räsänen visiting CBD (12.1.2015)
Dr. Katja Räsänen will visit CBD from January 12th to June 30th 2015. Katja is usually working at the Department of Aquatic Ecology at Eawag, in Zürich, Switzerland. She is the leader of a research group which aims to understand responses of natural populations to natural and human induced environmental change at ecological time scales (i.e. within a few generations). Her research is primarily empirical but with a strong conceptual basis. An important core in her research are interactions between agents of selection (e.g. single vs. multiple stressors; selection vs. gene flow), the quantitative genetic basis of adaptation (maternal vs. direct genetic effects) and those between ecological and evolutionary processes. Large scale field and laboratory experiments, combined with field surveys, quantitative and molecular genetics, as well as proteomics is used to answer the questions. Her study systems include amphibians adapting to environmental acidification, three-spine sticklebacks adapting to ecologically divergent environments and aquatic alpine macroinvertebrate responses to glacial retreat.

NEW Climate Research Project (16.12.2014)
Today the Research Council of Norway announced the results from the evaluation of applications to the Climate Research program "Fri Klimaforskning". Researcher Tim Burton recieved funding for his project "Adaptive plasticity meets unpredictability: how will organisms cope with changing temperature variability?". He will perform his work at CBD in collaboration with Sigurd Einum, and with the external collaborators Anders Finstad at the NTNU Museum of Natural History and Archeology, and Bettina Zeis, University of Munster.

CBD PART OF A LARGE INTEGRATED PROJECT IN CLIMATE RESEARCH (15.12.2014)
The Programme in Climate Research at the Research Council of Norway have decided to fund the project "Sustainable management of renewable resources in a changing environment: an integrated approach across ecosystems". This large integrated project will be operated by CEES, University of Oslo with CBD and the Department of Arctic and Marine Biology, UiT The Arctic University as the two major partners. The project will involve collaboration with many national and international institutions and aims to develop sustainable harvesting strategies of renewable resources in a changing climate using an ecosystem perspective.
PhD Javier Jarillo vistis (2.12.2014)
Javier Jarillo is a PhD student in the Out of Equilibrium Dynamics Group of the Universidad Complutese de Madrid (UCM) with a fellowship of the Spanish Ministry of Education. He studies out-of-equilibrium systems and stochastic processes, and their applications in diverse biological systems, which range from biomolecular systems to ecological systems. He collaborates with other researchers at the CBD financed by the European project “Stochastic dynamics in Ecology“ (005-ABEL-CM2014-A) founded by the the NILS Science and Sustainability program under the EEA Grants scheme. At the CBD, he aims to study stochasticity in ecological systems, specifically the effects of environmental stochasticity in spatial correlations of populations in two species models, and the evolutionary responses to fluctuating selection. He visits CBD from 30th January to 7th May 2015.
Post.doc Maja Tarka (25.11.2014)
Maja Tarka is starting a post-doc at CBD with C. Pelabon, B.E. Sæther and T.F. Hansen (UiO). Maja has defended her PhD at Lund University in 2012. She has worked on the evolutionary dynamics of migration and breeding of wild birds with D. Hasselquist and B. Hansson. She had a first post-doc on genomics of speciation in endemic finches on remote islands at CIBIO in Portugal with M. Melo and B. Hansson. Maja will now work on various subjects including temporal variation in fitness in bird populations and trying to understand why quantitative traits differ in their evolvability.
