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)
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".
Master student visiting CBD (20.02.2015)
We welcome Laura Sereni who has joined the Daphnia lab of CBD! Laura is doing her masters degree at Ecole Normale Supérieure, Paris, and is also attached to the Université Pierre et Marie Curie. She will stay here for 4 months doing an Erasmus internship. In her experiments she will study how activity levels of Daphnia respond to different environmental cues such as population density and food abundance.
Visit AURORA-program (3.3.2015)
This week we are welcoming French scientists from INRA Bordeaux and CNRS at Gif/Yvette and colleagues from Oslo as part of the AURORA program (NFR / CNRS). The visitors are Antoine Kremer and Cyril Firmat from Bordeaux Arnaud Le Rouzic, Estelle Runneburger, Clémentine Renneville from CNRS ,Thomas Hansen and Christine Mayer from Oslo. They will stay until Thursday 5. March.
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 genomics (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.
