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.

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.

Dr. Katja Räsänen visiting CBD (12.1.2015)
Katja inspecting a trap for three-spined sticklebacks during fieldwork at Myvatn, Iceland.Dr. Katja Räsänen will visit CBD from January 12th to June 30th2015. 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.

In addition, she will manage and  maintain the house sparrow BioBank, which now consist of more than 36 000 DNA and RNA samples from individual house sparrows. Linn-Karina has a strong background in molecular biology, has previously carried out research on the effects of gastrin on gene expression in cancer cells, and finished her PhD-thesis in Molecular medicine in 2013.

Erlend Fossen (01.09.2014)
Erlend will work with the highly suitable model organism Daphnia (waterfleas), which is representative for a wide range of key species in freshwater and marine food webs, and focus on one easily controlled environmental factor (temperature). He will study some target traits which may have effects on fitness that depend on both temperature and population density, and determine their potential for evolutionary changes. He will quantify how variation in temperature- and density-responses in these traits influences fitness across thermal regimes and population densities. The results obtained are expected to yield novel understanding of links between evolutionary and ecological responses to environmental change in general, and more specifically for temperature changes.

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".

New paper from CBD in Science (26-04-2013)
Great tit. Photo: Ivar HerfindalResearchers from CBD has contributed to a paper on how great tits cope with climate change, recently published in Science. Earlier springs have caused an advanced peak emergence of caterpillars.  Great tits have not been able to advance their timing of egg-laying to keep pace with the caterpillars.  This has caused an increasing mismatch between the food peak and the hatching of newborns, and early offspring survival in great tits have consequently declined. Density dependent juvenile survival do however come to the rescue - the decline in early offspring survival have been offset by increased juvenile survival as well as increased immigration during winter.  The mismatch have therefore so far not caused decline in pre-breeding population size.

The centre is now "Centre for Biodiversity Dynamics" (14-02-2013)
In connection with the establishment of the SFF (Centre of Excellence), CCB has now been renamed to Centre for Biodiversity Dynamics. The new name captures better the core activity at the centre; to understand processes behind spatial and temporal variation in biological diversity, at different organismic levels (from genes to ecosystems).

New reports about spread of alien species (23-01-2013)
Two Swedish raccoon dogs on their move. Photo: P.-A. ÅhlénMany alien species are regarded as harmful for native flora and fauna. Several of the species are introduced and spread by humans. For instance, alien conifers have long been an integrated part of forestry in Norway, and the raccoon dog was released in the former Soviet Union to increase fur hunting possibilities. In two reports to the Norwegian Directorate for Nature Management, members of the Centre of Conservation Biology have summarised the state of knowledge about spread and effects of alien conifers, and the movement pattern and dispersal ecology of raccoon dogs.

CCB in Science (17-01-2013)
Today, a paper entitled «Climate Events Synchronize the Dynamics of a Resident Vertebrate Community in the high Arctic» was published in Science, with lead authors from CCB and co-authors from NPI, NINA and UIT in Tromsø. The paper demonstrates for the first time how an entire community of species may be driven into synchronous fluctuations by climate. The high-arctic tundra study system in Svalbard hosts only four vertebrates in winter, all of which are influenced by rain-on-snow events in winter. Heavy rain-on-snow generates icing on the tundra, blocking forage for the herbivores (wild reindeer, rock ptarmigan, and sibling vole) and causing their populations to crash simultaneously. The arctic fox, which to a large degree relies on reindeer carcasses in winter and spring, crashes one year after the herbivores because of a distinct scarcity of carcasses in the winter following an icy (carcass-rich) winter. Rain-on-snow and icing events are expected to become more common throughout the circumpolar Arctic and have the potential to strongly Photo: Brage B. Hanseninfluence ecosystem functioning and stability.
The study was financed by the Norwegian research Council (NORKLIMA) and the European Research Council.

New projects at the centre (05-12-2012)
We are pleased to announce that the project  "The effect of population size on short-term rates of evolution in natural populations" by  dr. Henrik Jensen and dr. Aline Magdalena Lee's application for a post doc with the project "Effects of individual heterogeneity on stochastic population processes: the case of nonbreeders" have received support by the Research Council of Norway through the FRIPRO.

CCB-member Aline M. Lee with successful Marie Curie application
CCB researcher Aline Magdalena Lee has been invited to negotiate a Marie Curie IOF grant. The project will include a two year stay at the Steve Beissinger lab, University of California, Berkeley, followed by a year in the research group of Jane Reid, The University of Aberdeen. The proposed project is focused on analyzing the role of nonbreeders in driving population processes and extinction risk, by developing and analyzing new stochastic population models and applying them to two long-term datasets on wild bird populations (Green-rumped parrotlets and European shags).

The Centre will become a "Senter for Fremragende Forskning"

The Research Council of Norway (NFR) has today appointed our centre as a "Senter for Fremragende Forskning" (CoE). We are one of 13 new CoE in Norway. More information will follow. 
For more details regarding the new centres in Norway, see the announcement from NFR here: (Norwegian, English).

The theme of the workshop was "Canalisation, Modularity, Phenotypic Integration, and Adaptive Accuracy", and it was held at the Kavli Royal Society International Centre, at the Chicheley Hall, UK. Prof. W.S. Armbruster was the main organiser of the workshop, and 20 researchers from 9 countries participated on this 2-days event.

New book about wild ungulates in Norway
A new book has just been launched, entitled "Klauvvilt i norsk natur - historie, biologi og forvaltning" (Wild ungulates in Norwegian nature - history, biology and management). The book is financed by the Norwegian Directorate for Nature Management, as well as CCB. The book is edited by dr. Kari Bjørneraas (former CCB-employee), and CCB-members have contributed to several of the chapters. The book is written in Norwegian, and more information can be found from the publiser Akademika forlag which also offers online purchase.


Public information about research
Activities at CCB received considerable public attention in 2011. Our researchers appeared numerous times in national public media such as television (NRK Newton), radio (NRK, P5) and newspapers (Adressa, In addition, our projects attracted considerable local interests (e.g. Helgelands Blad). Further activities will be facilitated by a generaous grant from NTNU as part of NTNU's incentive to inform the public about ongoing research.

CCB has moved
CCB is now in the process of moving into a new area of the Realfagbygget at NTNU. The new area is located just above the main entrance of the building, and members of CCB will now have offices in the same wing on the 3rd floor, and in close proximity of each other.

The new CCB-area is located on the third floor (section E3), just above the main entrance of the Realfagbygget.

Members of CCB began the process of PhD student Stine Svalheim Markussen is happy with her new office. moving into their new offices early this week, and most of them are now settled in the new area. More information about the process of relocation will come. Dr. Henrik Pärn is moving into his new office in the CCB wing in Realfagbygget.



According to a study by researchers from Spain and Norway published in Nature - Dinosaurs were warm-blooded reptiles
The journal Nature has published a study analysing the lines of arrested growth (LAG) in the bones of around a hundred ruminants, representative of the specific and ecological diversity of that group of mammals. The results show that the presence of these lines is not an indicator of an ectothermic physiology (does not generate internal heat), as had previously been thought, since all warm-blooded mammals have them. The study therefore dismantles the key argument of the hypothesis that dinosaurs could have been cold-blooded reptiles. The main work was carried out by researchers from the Institut Català de Paleontologia Miquel Crusafont (ICP), in collaboration with a researcher from the Norwegian Polar Institute and Centre of Conservation Biology (CCB) at the Norwegian University of Science and Technology (NTNU).
Methods used in the study may be of crucial importance for investigating the effects of climate change on ruminants.

CCB improves method for ecological risk assessment of alien species
During the conference NATUR 2012, the Norwegian Biodiversity Information Centre (NBIC) publishes a complete listing of all 2320 alien species known to occur in Norway, classified according to their ecological risk. The set of criteria used in this ecological risk assessment has been developed by CCB, and evaluates all species according to their invasion potential and their ecological effects on native species and landscapes. In being semi-quantitative and generic, this set of criteria represents a great improvement over the earlier Norwegian Black List (2007). At the same time, this listing of alien species is the first complete national inventory and risk assessment of alien species world-wide.

Report from the workshop at Helgeland
This week (23-27 April) the Center for Conservation Biology arranges a workshop in "*Stochastic demography in fluctuating environments: theory and empirical patterns. The occasion for the workshop is Professor Russell Lande's award of the Balzan Prize 2011 for Theoretical Biology or Bioinformatics. In the stimulating programme Russell Lande, together with Steinar Engen and Bernt-Erik Sæther and coworkers share their advanced insight into stochastic processes in time and space. The 35 international participants are introduced to theory and various modeling techniques through lectures and discussions. The various techniques are also applied through practical exercises during the workshop.

The workshop is arranged at the beautiful remote island Lovund off the coast of Helgeland in northern Norway. The puffins have arrived, the house sparrows are preparing the breeding season and the white tailed sea eagles are circling over the island - and the weather is beautiful, which makes a perfect frame for the workshop.

Research at CCB on Norwegian television
Thursday 29. March, NRK will feature the sparrow project run by CCB. This will be presented at Schrødingers Katt at NRK1 Thursday 29. March at 19:45, and at NRK2 the following Saturday at 15:30.

Researchers at CCB receive funding from the Research Council of Norway
Three projects with project leaders or core members at CCB have successfully received funding from the Research Council of Norway recently.
Dr. Arild Husby's grant application for a postdoc position at Centre for Conservation Biology was one of only four postdoc applications that recieved funding as a free project within biology and medicine this year. The title of the project is "Genomics of adaptation to environmental change in two wild bird populations", and Arild Husby will start his work at CCB early in 2012.
The project "Predicting effects of climate change on Svalbard reindeer population dynamics - a mechanistic approach" has received funding from the NORKLIMA programme. Dr Brage Bremset Hansen at CCB is the leader of the project. The goal is to apply a multi-disciplinary approach to predict climate change effects on arctic ungulates, using high-arctic reindeer populations at Svalbard as a model system. Project partners include the Norwegian Meteorological Institute, James Hutton Institute, University of Aberdeen, Norwegian Institute for Nature Research, Norwegian Polar Institute, Northern Research Institute, Norwegian University of Life Sciences, Norwegian School of Veterinary Science, and the University Centre in Svalbard.
The project "Intensified harvesting of forests - implications for enterprises related to wild and domestic ungulates" received funding within the NFR-programme Nature-based industry. The project leader is Hilde K. Wam at the University of Life Sciences, and CCB is involved through Ivar Herfindal as a core member of the project. The project will assess how changes in forestry affect other enterprises that depends on ungulates that utilise forest ecosystems, through its impact on behaviour, resource and habitat utilisation, and life history traits of the ungulates.

Centre for Conservation Biology ranked "Excellent" in national evaluation
The Research Council of Norway has made an evaluation of the biology, medicine and health research in Norway. The Centre for Conservation Biology was one of three groups at NTNU that got the highest grade; Excellent.
