We wish you all a merry christmas!
MEDIA & OUTREACH
In 2011 our new webpage was released. Thanks again for all your help with input and ideas of content and design. We see this as our communication platform, which will continue to develop during the program period. Some of the new parts on the web-page were for instance: short science films produced in collaboration with journalist Joakim Lindhé (with support from Lars Salvius Stiftelsen to S. Åkesson). CAnMove members participated in a TV program for “Vetenskapens Värld” in Swedish Television with a program about bird tracking technology (project run by journalist Joakim Lindhé with financial support from FORMAS).
Other new actions was the field blog where CAnMove members reported from their field work, and a nation-wide moon watching project, which was run in collaboration with Swedish Ornithological Society (SOF). A spectacular Music show “Music of Migration” was part of the Migration course to which Lund University employees were invited.
COURSES & CONFERENCES
The international PhD student course “Ecology of animal migration” was this year coordinated by Rachel Muheim and Maria Eng Johnsson and attracted 36 participants, from many different countries. Thanks to the participants for their interesting contributions, active and friendly attitude during the course. You all make it worthwhile to invest the work in organizing the course! Many lecturers were invited and we are grateful for all high-quality and stimulating contributions to the course by visiting as well as Lund-based lecturers and student teachers! Thank You!
The internal CAnMove conference were held at Hotel Norregård in Falsterbo, at which two of the CAnMove Science Advisory Board members Prof. Marilyn Ramenofsky, Davis and Prof. Steven Repperert, Massachusetts were participating. The creative brainstorming event and feedback were most valuable, and the Steering committee is very pleased with all creative input to the program outline. Thanks to you all! Next conference will be held in early spring 2013.
A conference on animal migration at Sven Lovén Centre for Marine Research was held in June and was organized by the Royal Academy of Sciences (program coordinator Thomas Alerstam) to which some CAnMove members were invited. Much stimulating discussions and excellent organization, which we are much grateful for!
In August postdoc Sophia Engel organized a workshop on “insect flight”, while a workshop on “Beyond the climate envelope” was held in collaboration with BECC, the workshop was organized by Catherine Davey. The meeting was attended by members from both programs as well as by invited lecturers and was very stimulating for the discussions on effects of climate change. Well done!
POSTDOCS
Two new postdocs were hired within CAnMove – Sylvie Tesson (supervised by Karin Rengefors and Katarina Hedlund) with focus on Community metagenomics of Antarctic Protists and Brianne Addison (supervised by Helena Westerdahl, Dennis Hasselqvist and Jan-Åke Nilsson) who works with Immunological and physiological adaptations to migration.
Our first three postdocs (Sophia Engel, Ben Chapman and Miriam Liedvogel) have all ended their postdoc supported by CAnMove, but both Miriam and Ben have received funds to stay here for some more time, financed from other grants. And we are very happy that they have decided to stay and work within the CAnMove program for a bit longer. Most welcome!
INTERNAL INFORMATION
CAnMove has initiated a gender equality group, coordinated by Rachel Muheim, with support from a team of female scientists and students. The first meeting was held in December 2011.
Some CAnMove members were participating in the local running competition “Lundaloppet” in one of the two CAnMove teams. We aim at having more than 2 teams in spring 2012. We will continue with the CAnMove breakfasts and seminars in 2012.
We like to thank all members contributing the research and creativity of the CAnMove program! We are looking forward to a new stimulating year 2012 and would like to encourage you all to approach any of the employees or the steering committee or the coordinator with suggestions and ideas.
In time for the Christmas celebration this year, the special Volume of Oikos on partial migration is published, in which a number of review articles are included. This is as a result of the CAnMove workshop “Partial migration” organized by Ben Chapman and co-workers last autumn. We are very pleased with the outcome and congratulate Ben et al. for this successful publication!

The Ecology and Evolution of Partial Migration

Partial migration, where populations of animals are composed of both migratory and resident individuals, is widespread in nature, and taxonomically diverse. Last year CAnMove hosted a two day symposium into the ecology and evolution of partial migration, and from this workshop we compiled a number of original research articles to create a special thematic issue of Oikos focussing upon this fascinating phenomenon. The papers in the thematic highlight the breadth of work carried out in this field of migration biology, and showcase exciting new research into various aspects of partial migration.
To begin with we present a review of the current literature, and discuss what is known about the ecology and evolution of partial migration and what the future may hold (Chapman et al. 2011). Next, Francisco Pulido presents a revised threshold model of migration, which aims to understand the proximate basis of individual migratory tendency. Pulido revises the current threshold model to include environmental effects (Pulido 2011). Following this, CAnMove’s Anna Nilsson and coauthors (2011) investigate the physiological adaptations of migration in the partially migratory blue tit, showing that residents have a higher basal metabolic rate than migrants in this species. Next, Francesca Cagnacci and coauthors (2011) analyse data on roe deer migration from 5 different countries to understand the environmental correlates of partial migration. They also importantly highlight that partial migration is on a continuum between full residency and full migration.

The next series of papers investigate the ecological drivers of partial migration. Alice Boyle presents a community-level test of the ‘limited foraging opportunity’ hypothesis, and finds support across a range of Neotropical bird species for the importance of this mechanism (Boyle 2011). Atle Mysterud and co-authors (2011) show that a range of ecological factors are important in shaping patterns of red deer partial migration, and also show evidence for negative density-dependent migration in this species. Next, Hanna Kokko theoretically models the role of intraspecific competition in facultative partial migration, illustrating how important the strength of the prior residency effect is in predicting which individuals migrate (Kokko 2011). The following paper focuses upon the consequences of partial migration. Jakob Brodersen of CAnMove presents a long term data analysis of partially migratory roach, a freshwater fish, and the effects of this migration on an ecosystem level (Brodersen et al. 2011).
The next series of papers look at how anthropogenic influences can affect patterns of partial migration. Cort Griswold presents a theoretical population model of partial migration which is applied to scenarios of environmental change (Griswold et al. 2011). Mark Hebblewhite shifts from theory to empirical data, and using demographic data analysis shows how human impacts can affect migrants and residents differently by altering the costs and benefits of migration vs. residency in ungulates (Hebblewhite & Merrill 2011).

The final paper broadens the classic definition of partial migration to include animals that migrate to breed, but sometimes forgo breeding (Shaw & Levin 2011). Allison Shaw presents what may be the first theoretical investigation of this kind of partial migration.
All in all, I think we have something for everyone! A diverse and interesting issue for a diverse and interesting subject. We are really pleased that the thematic is out in time for Christmas, and thanks again to all the CAnMovians that helped out with the workshop or the thematic production! God Jul!

CAnMove Conference, day 2
After this discussion it was time for Mikael Ekvall to talk more about the work to track small animals, in this case daphnias, with nano technology. You can see one example of how it can look like here
Mikael shows us a movie of nanotracked daphnias |
Steven Reppert held an interesting talk about monarch butterflies and how they use circadian clock and sun compass during migration. One thing he mentioned was that they have found out that the circadian clock that the butterflies uses for navigation is situated in the antennae instead of in the brain, as was thought before. Rachel Muheim continued the orientation/navigation theme and told us about magnetic compass orientation in migratory birds, and many other animals that also uses this way to find their way.
Steven talks about time-compensated sun compass orientation |
Now it´s time for lunch together and then the bus will drive us back to the Ecology building in Lund. It has been a conference filled with good and interesting talks and interactive discussions. Thanks to Hotel Norregård that served us with everything we needed and to all the participants that interacted and gave us good tips and advices on how to make CAnMove even better in the future!

CAnMove Conference in Falsterbo
Steven Reppert is professor of neuroscience and founding chair of the department of neurobiology at the University of Massachusetts Medical School and Marilyn Ramenofsky is adjunct professor at the department of neurobiology, physiology and behavior at the University of California.
Marilyn Ramenofsky gave us a small glimps of her work |
Today we have heard Anna Runemark talk about the Lidar and spectroscopy of damselflies, Christoffer Johansson has tought us about the wing difference between insects, birds and bats and Marilyn Ramenofsky told us about her research on regulation of endocrine, metabolic and behavioural systems in migratory birds
Anders Hedenström and Steven Reppert discuss the possibility of letting butterflies fly in the wind tunnel |
After some coffee Max Lundberg and Keith Larson talked about the willow warbler where the subspecies migrate to different areas in Africa and then it was time for some fantastic lunch!
After this energy boost we continued the conference by listening to Catherine Davey that informed us about how the climate change affect the Swedish birds. Anders Hedenström told us about the swift "Argus argus" flight and then Cecilia Nilsson let us know more about how migration speed in passerines differ between spring and autumn migration.
