Get a glimpse of the research at CCB >>
NRK has joined the house sparrow project in field, and learned how research at CCB addresses important questions related to environmental change.

 
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)

Håkon Holand gets his PhD-title (20-06-2014)
This Friday Håkon Holand defended his PhD-thesis entitled "The parasite Syngamus trachea in a metapopulation of house sparrows". Håkon first gave a trial lecture on the assigned topic "Pattern and process in spatio-temporal dynamics of parasite-host dynamics", before he discussed his work with the two opponents Professor Peter J. Hudson, Penn State University, US, and Professor Xavier Lambin, University of Aberdeen, UK. CBD contratulates Håkon with a well deserved degree.

CBD-member offered position at Department of Biology (19-06-2014)
Dr. Henrik Jensen was today offered the position as associate professor in population genetics at the Department of Biology, NTNU. Dr. Jensen has been a member of CBD for most of his research career. CBD congratulates with the great achievement.

 

 

Eirin Marie Bjørkvoll defended her PhD (06-06-2014)
After a trial lecture on the topic "Cost of reproduction and their influence on life-history evolution", and a public discussion of her thesis (Life-history variation and stochastic population dynamics in vertebrates) with the two opponents, prof. Jeffrey A. Hutchings, Dalhousie Unviersity, Canada, and dr. Michael Schaub, Swiss Ornithological Institute, Eirin Marie Bjørkvoll obtained her PhD today. CBD congratulates with a well deserved title.

The Sparrow-projct in media (05-05-2014)
This weekend the house sparrow project was covered in commercial media, with comments from Prof. Bernt Erik Sæther. Read more at VG and forskning.no

Report from the Field (21-03-2014)Fieldworker Malene Dimmen has just captured a female house sparrow
The winter's house sparrow fieldwork is well under way, and has been very successful so far. PhD student Ane Myhre and her fieldworkers are carrying out experiments to alter demographic stochasticity and effective population size in a set of natural populations. In another set of natural populations postdoc Bernt Rønning and his team of PhD-students, MSc-students and fieldworkers is doing large-scale experimental studies of basal metabolic rate.

Postdoc Marlène GamelonPost.Doc Marlène Gamelon (24-02-2014)
We welcome Marlène Gamelon to CBD!
Her research at CBD will be as follows: "Life history traits co-vary with each other, shaped by evolutionary trade-offs, at the individual scale leading to a large range of demographic tactics. Demographic tactics are thus variable among individuals, among populations but also among species. My main research activity seeks to understand the responses of species spanning a large range of life history tactics to variable environments. My research thus combines evolutionary demography, population dynamics and modelling. Key words: Demography, Evolution, Life history, Population dynamics, Wildlife".

CBD research in Smithsonian Magazine (24-02-2014)
The March issue of the Smithsonian Magazine features a longer article on Svalbard reindeer research and the REINCLIM project lead by CBD. This story also provides insights into the life in field in the High Arctic (read the article and see video clip online here : >>.

Course in Stochastic population models (16-12-2013)
The course "Stochastic population models" (ST2302) will be given by professor Steinar Engen during spring 2014. The course deals with different models for population growth, demographic and environmental stochasticity, effects of density and age-structure on population growth, harvesting models, sensitivity analyses and diffusion processes. For more information, see here >>

CBD-project gets funding from Norwegian Research Council (04-12-2013)
CBD is happy to announce that the project "Eco-evolutionary dynamics of thermal reaction norms" lead by professor Sigurd Einum was one of the 17 research projects that this year were funded by the Research Council of Norway through the FRIMEDBIO programme. The project will mainly focus on how metabolic rates of Daphnia are affected  by environmental variation and population density, working both at ecological and evolutionary time scales and using a large number of experimental populations. The project will involve several people at CBD.

Warmer, wetter, wilder Svalbard winters (27-11-2013)
A new CBD project called «WINTER RAIN» has received support from the Svalbard Environmental Fund. This multidisciplinary project will analyse historical and future changes in winter climate in Svalbard, and explore the ecological and societal consequences of such chaPhoto by Øystein Varpe: Longyearbyen during the Polar night in early February 2012, following an extreme warm spell and heavy rain event.nges. During recent decades the Svalbard winter has become milder, increasing the probability of precipitation falling as rain rather than snow. Extreme warm spells and rainfall has major impact on the environment by increasing the danger of avalanches, influencing the permafrost, and generating ground-ice on the tundra. Project leader is Brage B. Hansen, and collaborators are Akvaplan-NIVA, UNIS, Norwegian Meteorological Institute, Norwegian University of Life Sciences, and University of Aberdeen.
