News from CBD

 

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.

Field work in Costa-Rica (15.10.2014)
Elena Albertsen and Øystein H. Opedal have reached  Costa-Rica and located their first Dalechampia populations. They will both stay in Costa-Rica until early January 2015 to study the effects of local variation in pollinator fauna on the morphology of the Dalechampia blossom.  Their main questions are 1) to analyze how selection exerted by pollinators and seed predators on several traits of the Dalechampia blossom varies spatially and temporally, and 2) whether the degree of herkogamy (spatial separation between male and female flowers to prevent self-pollination) varies with the availability of pollinators. This work is done in collaboration with R. Pérez-Barrales and W. S. Armbruster from Portsmouth university who will soon join them on the field for few weeks.

Linn-Karina Selvik (19.09.2014)
Linn-Karina started working as a research technician at CBD 1 September. She will be part of the research group of Dr. Henrik Jensen and employed on the project "The effect of population size on short-term rates of evolution in natural populations" funded by the Norwegian Research Council. Her responsibilities will be to carry out molecular genetic laboratory work and various bioinformatics analyses related to our research on genetics and genomics of house sparrows. 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.

Varvara Iashchenko (26-08-2014)
Varvara Iashchenko started on 11-th of August as a research technician at the CBD, she will be working in the Dapnhia lab on the project "Eco-evolutionary dynamics of thermal reaction norms" funded by the Norwegian Research Council.
Varvara graduated in 2004 from the Saint-Petersburg State University with specialization on zoology of invertebrates and later worked on fresh-water symbiosis of alga and ciliates. She will be responsible for Daphnia pulex cultures, their maintenance and growth, establishing protocols for measurement experiments, helping researchers with routine tasks and methods.

Postdoc Marlène Gamelon (24-02-2014)Post.Doc Marlène Gamelon
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".

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.

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.

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. More about the content and links to the reports can be found at the Norwegian Directorate for Nature Management's web pages:

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.

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.
