Drought in Africa delayed arrival of European Songbirds


The late spring arrival of several European songbirds puzzled bird watchers and researchers in 2011. Especially since many of these trans-Saharan migratory bird species have been shown to arrive progressively earlier over the last 50 years due to climate change.

In a study published in Science, December 6th, CAnMove researchers in collaboration with Danish collegues reveal that the delay of red-backed shrikes and thrush nightingales in 2011 was caused by a prolongation of stopover time during spring migration at the Horn of Africa, which was affected by extreme drought.

All systems go!


We are approaching 10 years of studying the mass migration of freshwater fishes from Lake Krankesjön into the connecting streams! Nearly time for some kind of party…
The old antenna system has served us well, but recent support from CAnMove and Fysiografen has enabled us to modernise. To study fish migration we use passive telemetry, collecting data on the movements of tagged individuals with continuously operating antenna stations in every stream. Last year we installed a brand new and upgraded system, which required a new database to handle the millions of data points generated by the seasonal movements of mostly cyprinid fishes. We hosted Dr. Henrik Baktoft of the Danish Technical University, who, along with CAnMove’s Johan Bäckman, built a custom-made database to hold old data and process new information gathered by the system.

Fysiografen also funded the project 170 ksek to modernise the system further. We will install solar panels at the remote antenna stations so that our migration research will have a self-supporting energy supply. In addition we will install technology that allow us to send the data from our study site straight to Lund via mobile phone satellites and into the database on a daily basis. This will save us time and also make the project a great deal more environmentally friendly!
Our aim is to have (almost) real time data from the fish migration available on the CAnMove webpage, so that fellow migration enthusiasts can follow the fish as they migrate. This advanced and upgraded system will also support us in our current projects, which include investigating sex differences in migratory behavior, experimentally manipulating predation risk to assess migratory plasticity, evaluating the impact of pollutants upon migration and searching for the mechanisms of navigating during migration. It will also help us develop a longer-term project, which aims to quantify some of the costs and benefits associated with migratory versus resident strategies. The future is bright! Thanks to CAnMove and Fysiografen for their support!

With that diet, you will go far!


Butterflies and moths expand northwards quickly. But some move faster than others. A new study by Lars Pettersson and collegues, covering 37 years of range expansion in Sweden reveals that diet can play a major role. Specialist species whose larvae feed on nitrogen-favoured plants spread northwards more rapidly. The researchers demonstrate that expansion rates depend in predictable ways on traits such as diet specialization and habitat affinities. This suggests that increased areas of nitrogen-rich habitat, and increased availability of nitrogen-favoured diet, are among the most important drivers of range expansions, potentially having far-reaching consequences for a wide variety of organisms.

CAnMove book camp


Helena, Miriam and Åke
The lead authors of the CAnMove book “Animal Movement Across Scales” recently met at nearby “Gården” providing a cosy and friendly atmosphere for the book camp. 

Lars-Anders Hansson led the program extending over two days which involved creative discussions, brainstorming and discussions on cross-referencing covering the topics of all different book chapters.

Version #1 of the book was at the table and the mission of the book camp was to find connections between chapters and to update contents of each chapter and thus help the authors to move the book to a final stage to be available for review early next year.

Ben, Johan and Glenn
We hope to produce a book of interest for advanced students and interested scientists in the field covering basic theory and understanding, but also high-lighting exciting new findings. Topics like, effects of climate change on movements were discussed as well as spread of diseases by migrating animals, adaptations related to locomotion and navigation, genetics of migration and migration patterns. 


The locomotion expertise; Anders and Christoffer

The book camp was a very successful step in this process and gave the participants an excellent chance to interact with the other scientists in the program.

New publication on geomagnetic bi-coordinate navigation

A bi-coordinate map sense based on geomagnetic information was first suggested by Viguier, almost 130 years ago, but it did not receive much attention until the beginning of this century. The magnetic map hypothesis in animal navigation has attracted an increasing amount of attention during the last decade and magnetic navigation has been demonstrated in several animal species from widely separated taxa.

In a recent paper by Boström et al. 2012, published in Ecography, we investigated the global geomagnetic prerequisites for geomagnetic bi-coordinate navigation in order to pinpoint possible problematic, as well as suitable, areas for migrating animals. We analysed the angular difference between isolines for inclination and total field intensity on a global map divided into 3° lat. × 3° long. squares and produced a map illustrating different regions of the earth defined by different angular intervals. This map revealed four vertical bands of little or no variation between isolines (‘no-grid’ zones) in the northern hemisphere as well as a few areas in the southern hemisphere. Most part of the globe show intermediate angular difference (2-30º), but there are also large regions both at northern latitudes and in the Pacific, Indian and south Atlantic Oceans where the two isolines form a clear grid.
Illustration of the possibility for animals to use a bi-coordinate map based on geomagnetic inclination and total field intensity ona global scale. Areas with an angular difference of 2 ° are shown in red, 2– 30° in yellow and 30 ° are shown in green.
We also analysed how the geomagnetic field varied along four assumed migration routes as well as two fictive routes across the US that may have been followed by birds geographically displaced in this region. For animals migrating long distances across longitudes we discovered a possible cause of difficulty. When moving east-west across one of the ‘no-grid’ zones stretching north-south the animals have to first move against higher values for both total field intensity and inclination, past a peak and then continue towards lower values. For juvenile individuals using an innate navigation system more complex than the clock-and-compass model, this information would have to be incorporated into the endogenous migration program. We also discussed possible problems for animals dealing with the ambiguity that may arise when migrating in regions where mirrored combinations occur. These mirrored combinations often occur on both sides of the north-south stretching ‘no-grid’ zones and will hence also affect animals moving east-west across longitudes.

Climate change affects Swedish bird life

Within the Swedish Bird Survey, the population size changes of Swedish breeding birds is monitored. Given that it started already in 1975, it constitutes a rich source of long term data. In a number of recent studies, Åke Lindström and Martin Green has collaborated with French researchers to investigate how the last decades of increased temperature in Sweden has affected bird life.

One approach was to investigate how the proportion of warmth-loving and cold-loving species has changed in Sweden. To start with, all bird species in the study were classified in relation to the average temperature of the species’ breeding distribution in Europe (STI, Species Temperature Index). The Siberian tit, for example, bredding in northernmost Europe only, get a STI of +6.9° C. It is a ”cold” species. The Goldfinch, with a STI of +15.3° C, is a ”warm” species. The average STI of all birds in a given site is the ”Community Temperature Index” (CTI). The CTI was calculated for a large number of sites around Sweden and compared over years (Lindström et al. 2012). Generally, CTI increased over time at most sites in Sweden, in parallel to increasing summer temperatures. Clearly, as Swedish summers get warmer, we get more and more warmth-loving birds. This is primarily because the “warm” birds of southern Sweden become more common and also move northwards, and to some extent that “cold” birds of northern Sweden retreat northwards.   
However, the study also showed that, while a given summer temperature moved about 300km north during 1975-2009, the bird communities only moved 100 km north – thus lagging behind about 200 km!  The birds are not moving as fast as the climate. Although the long term effects of this is not yet known, a potential problem could be that the birds get out of phase with important resources, such as food and habitat. A similar study on birds in Europe (Devictor et al. 2012), where Swedish data were included, showed a similar trend. It also revealed that butterflies were much better in following the changing temperature, possibly due to their much shorter life span.
Another European study, using data from the Swedish bird survey, showed that habitat generalists are doing better than habitat specialists (LeViol etal. 2012). This trend was visible throughout all of Europe, but most apparent in Sweden.
Based on several different forecasts of climate and landscape changes, the Swedish Bird Survey data also formed the basis of detailed scenarios on how the Swedish bird population will be distributed in 2050 (Jiguet et al. 2012). These scenarios show that the population changes the last decade follow the pattern of the predicted bird distribution in 2050!
Even though there are other factors affecting bird numbers, such as land use, the above studies clearly reveal that current climate change affects the Swedish bird populations here and now.

Differential orientation in Scandinavian willow warblers explained by genotype

Photo: Dimitar Dimitrov

The willow warbler (Phylloscopus trochilus) is a tiny passerine capable of flying thousands of kilometers during long-distance migrations from the temperate regions of Europe and Asia to Sub-Saharan Africa and back. Just like most European songbirds, during their first autumn migration these small birds are flying alone in the night guided by their endogenous migration program. Willow warblers breeding in southern and northern Scandinavia belong to two different subspecies. Due to the efforts of a group of scientists from Lund University both subspecies can now be distinguished by genetic markers. Ringing recoveries and stable isotopes show that the willow warblers from southern and northern Scandinavia migrate to different wintering areas in Africa.

In a recent paper by Ilieva et al. 2012 published in Behavioural Processes we used orientation cages to show that the autumn migratory orientation of the Scandinavian willow warblers depends on their origin. Genetically assessed southern and northern birds headed south-west and south-southeast, respectively. Depending on whether the birds were tested far from the coast or at the southern tip of the island of Öland, they oriented in a different way. Willow warblers tested in front of an ecological barrier, the Baltic Sea, were less active compared to the individuals tested inland, especially when overcast conditions were simulated by placing Plexiglas sheets on top of the cages. More individuals also showed reverse directions at the coast, a phenomenon often observed in coastal areas. The current experiments show the potential of using orientation cages to study inherited migratory directions in willow warblers. Future studies of the orientation of hybrids between both subspecies will be crucial for a broader understanding of the mechanisms underlying the determination of migration direction.

Version #1 of The Book now ready!


One of our main aims when CAnMove was launched was to produce a book on Animal Movement Across Scales. We have now worked with the book project during 2012 and, as you see on the photo, Version #1 is now finished. 
In this version all authors (about 40 persons!) have displayed a draft text of their chapter. This draft will serve as a basis for a lead-author meeting 12-13 Nov, where we will “make 14 chapters transform into a book”. In January 2013 the next version will be ready and that will be sent for review. After revision and editing of all chapters the final version will be handed over to the publisher which we have contract with (Oxford University Press). The book will then be on the shelf in renowned book stores in May 2014.

Newsletter CAnMove Autumn 2012


The autumn migration season is coming to an end and we are currently observing redwings and buzzards arriving late from the north heading for wintering sites to the south. Herring gulls and eider ducks are also moving south along the Swedish coasts. It is time to prepare for the winter.
I have with great joy noted that the stream of publications from the CAnMove program is stronger than ever, and many PhD Theses have been defended by students associated with CAnMove. The PhDs are ending their studies in the most excellent way, entering the next stage of their career. Congratulations to the many impressive PhD Thesis, interesting discussions and stimulating seminars which has taken place in association with the Thesis defenses! On the behalf of CAnMove I wish you all good luck with future careers!
CAnMove members are currently strongly involved in the production of the planned text book Animal Movements Across Scales to be published by Oxford University Press. Lars-Anders Hansson is leading the work with energy and strong engagement, making sure the time line is kept. Thanks for this Lasse! We are looking forward to stimulating interactions between scientists which will be a synergetic bi-product of the work. The book will we hope reach the sales desks in 2014.
CAnMove members have invited scientists from the Linnaeus program LCCC (Lund Centre for Control of Complex Engineering Systems; coordinator: Anders Rantzer, Anders Robertsson and co-workers), at LTH to a joint seminar with LCCC. The meeting is open to all interested and the invited scientists will present their work and will occur 15 November 13.30-16.00 at the Ecology Building. All interested are most welcome to join and discuss cross-disciplinary work and technological applications to biological movement research. Please, check CAnMove web page for location and detailed program.
Johan Bäckman and Susanne Åkesson will visit WRAM at Umeå University during end of November to discuss how we may interact and use combined efforts in database work associated with our actions as one of the nodes in LifeWatch Sweden.
The CAnMove program has entered the stage during which we are preparing ourselves for the mid evaluation taking place in 2013 by the Swedish Research Council. A financial evaluation is currently taking place within Lund University. The coming year we will prepare ourselves for the evaluations, and we will ask scientists and students associated with the program to contribute to the evaluation. I am convinced we will make a strong case when presenting our joint achievements, and when reviewing our work I am amazed by the number of activities and new findings that have been generated with support from CAnMove. I feel privileged and proud to represent the program as a coordinator and I look forward to work with preparations of the evaluation with you!
During the coming months the Steering committee will revise the action plan, as well as communication and equality plans for 2013. We welcome input and suggestions from CAnMove members, and please feel free to approach me or other members of the steering committee so that we can take suggestions under considerations with the benefit of the program.

Spectacular multi-generational and long-distance migration revealed in the painted lady


One of the most spectacular and widely known long-distance migrations by insects is the multi-generational migration by Monarch butterflies Danaus plexippus, in North America. Monarchs are migrating north in spring to breeding sites as far north as southern Canada and returning to wintering sites in mountainous forests in Mexico. The migration distance and number of generations involved are now beaten by the European migratory butterfly, the painted lady Vanessa cardui. In one year the painted lady is migrating from tropical Africa to northern Europe and back, twice the distance the monarch butterfly is covering in the same time. The painted lady, unlike the Monarch butterfly which is hibernating in winter, reproduces all year around but at different latitudes. It takes the painted lady six generations to cover a round-trip distance of 15 000 km (up to 60 degrees of latitude and back). In some years (like in 2009) the painted lady shows massive migrations, which may be performed also at high altitudes out of sight from entomologists and migration watchers.
Photo: Pål-Axel Olsson
In a recent paper by Stefanescu et al. 2012 (now available as early view) published in Ecography we describe the migration phenology for the painted lady across its continuously breeding path from winter and early spring in tropical Africa via central Europe to the most northern locations in northern Europe in summer and back. The migration of the painted lady is spectacular and show the migration of a habitat generalist and highly polyphagous migrating butterfly adapted to migration in a temperate region. Radar observations show the selectivity to winds and use of high altitude flights to reach more distant areas for breeding which has been observed for other insects too and suggest that the migration strategy may be widespread among insects in temperate regions migrating long distances.
The data set included in the paper contains more than 60 000 observations from the Palaearctic and benefit strongly from national observation schemes (“citizen science”), such as those compiled in the Swedish “Artportalen”, included in LifeWatch Sweden. On the behalf of all co-authors - thanks to all who reported observations of this charismatic long-distance migrating butterfly!

Postdoc position in evolutionary ecology in Svalbard

A 2-year postdoc position in evolutionary ecology is available at the University Centre in Svalbard (UNIS). The project is on modeling of zooplankton life histories and behavior.

The full announcement is available HERE.

"The Post Doc position is on modeling of life history strategies and annual routines of copepods. Our modeling work is motivated by the ability of mechanistic models to look beyond what can be learnt from observed correlations and predict biological responses to environmental change scenarios. The candidate must have a PhD, or equivalent degree, in biology, computer science, or related fields. We look for individuals with experience from quantitative approaches to ecology, including programing skills, and that are familiar with life history theory, optimization models or individual based models."

The birdy smell of a compatible mate


Blue petrel
Animals are dependent on their nose in many aspects of life. Tasks like food search, navigation or kin recognition often include the ability to evaluate odours and migrate towards or away from them. Humans and several other animals can even sniff their way to picking a compatible partner. By choosing a mate that smells right, individuals can produce healthy babies with efficient immune systems. In contrast to many animals birds have generally been thought to have a poor sense of smell, but there are exceptions. The Blue petrel is an Antarctic sea bird with a remarkable sense of smell that it uses to recognize its partners, to navigate and to find food.

A few weeks ago, CAnMove associate Maria Strand (together with Helena Westerdahl, Björn Canbäck and researchers at CNRS, Montpellier in France) published an article that shows that the nose of the Blue petrel is even capable of smelling which mates will produce kids with the best immune systems. To the article in Proceedings of the Royal Society B!

Swedish storks breaking new migration records!

The Swedish Reintroduction Project on White Storks is running better than ever. Yet, the work with this long-distance migrant bird has been all but straightforward, and a major obstacle has been the birds’ unwillingness to migrate. The turning point came two years ago when about 25 juveniles left Skåne on their first autumn migration.
Equipped with a GPS by Raymond Klaassen & Berith Cavallin.
This year, two juveniles were equipped with 35 gram solar GPS from Northstar. Thanks to Johan Bäckman at CAnMove the storks’ journey has been possible to follow on a map on the project’s webpage. The migration routes and wintering areas of these birds are typical to the European storks of today. One flew southeast, through east Europe, the Bosporus, crossed the Sinai dessert and stopped at the pre-wintering area in Tchad. After three months it headed south and reached South Africa at New Year’s Eve. The second stork migrated southwest and stopped at a rubbish dump in Spain. In fact, half of the west migrating population winter in the Iberian Peninsula, whereas the rest carry on to sub-Saharian West Africa. The study was funded by Foundation Lund Animal Welfare Fund.

In 2011, the number of migrating storks reached 100 – a magnitude similar to long before local extinction! The large number was made possible by the release of some 70 captive bred juveniles. Even this year captive juveniles were released and almost 90 storks migrated. In 2014 the first storks are expected to come back to breed. This will be a critical step since recruitment has to be sufficient for a sustainable population in Skåne. During the next couple of years the project will expand to new localities in Skåne where pairs will be released to settle and breed. Photos: Emma Ådahl. www.storkprojektet.se

An ode to the technical development lab of CAnMove

One of the pillars of the CAnMove research environment is the advanced technical development laboratory and now, a few years after the start of the programme, the investments in this laboratory are indeed carrying fruits. For example, the advanced temperature steering system applied in the large-scale aquatic experimental set-up, the “WarmBrown experiment”, was developed by the CAnMove technical development lab. This temperature steering system continuously adjusts the temperature in treatment enclosure 3oC above the ambient, allowing us to mimic future temperature regimes in a climate change perspective.   
Based on this technology (and some biological thoughts…), we recently showed that the spring dynamics in freshwater systems will change considerably in the future. However, the different trophic levels will advance their peak abundances in a similar pattern, i.e. there will be no mis-match between consumer and prey (Nicolleet. al 2012, Freshwater Biology). Moreover, we have shown that future elevated temperatures will mainly benefit the top trophic level, and each second level below (Hansson et al. Nature ClimateChange 2012), a finding allowing us to mechanistically connect traditional food web theory with climate change scenarios. 
Recruitment trap
Finally, we show that elevated temperatures will lead to stronger and earlier recruitment of zooplankton from the sediment to the water column (recruitment quantified by means of submerged traps, see photo), i.e. affect movement and dispersal (Ekvall & Hansson, PloS one, 2012). However, this effect is stronger for some species than for others, suggesting considerable alterations in community composition in future aquatic ecosystems. 

Hence, the technical laboratory platform of CanMove, lead by professional and service minded personnel, in combination with proper application of those advancements to scientific questions, have indeed been a fruitful strategy and the above studies are just examples. There are more to come!

Following last week's ISBE2012 conference, hosted by Lund University, we ended the week with a CAnMove symposium on the behavioural ecology of animal movement.
It was a great day with a lively and highly diverse group of people from all over the world working on all sorts of disciplines related to behavioural movement ecology.
The breadth and diversity of the topic was apparent from the plenary talks we listened to, covering different magnitudes of tracking distance and movement patterns, looking at behavioural strategy and responses of both wild but also caged animals. Questions addressed covered: What are the sensory processes? How does ecology shape group strategies and sociality and vice versa? (How) does this differ in different habitat and for different species and communities? How does the underlying genetic architecture of these movement traits look like?

In addition to highly inspiring talks, we enjoyed ample opportunity for poster presentations, discussions and change of ideas, which we then synthesized in a final plenary discussion - before ending this day in glorious sunshine with delicious dinner at Kulturen.
Thanks to all of you, making this symposium a real highlight.

Spotty cows avoid horsefly bites

A warm summer day the air is full of insects, such as pollinators, butterflies and blood sucking dipterans. Tabanid flies (or horse files) can in many areas be an annoying pest to grazing horses and cattle. The horse flies bite to suck blood from the mammalian host and use the blood meal to produce eggs. These eggs are later attached to vegetation near to water and ponds, in which the larvae develop. The tabanid flies can see reflected linearly polarized light and use this information to locate water and mammalian hosts. In a recent paper published in PLoS ONE we demonstrate that the coat pattern of cattle is crucial in attracting the biting flies, such that the more spots you have the less attractive you are. Cattle have been bread to increase meat and milk production, with limited focus on coat pattern appearance. However, for the future we suggest that also this feature should be considered in cattle farming in order to minimize spread of diseases to cattle and to minimize disturbance during grazing. It is interesting to note the typical coat pattern of the ancient Swedish cow race “fjällko” (photo above), which seem to have an ideal coat pattern in order to avoid horsefly bites – predominantly white with black spots.

Sign up for the symposium!


This summer CAnMove will host a symposium in the "Behavioural Ecology of Animal Movement" at Lund University on August 18th. The symposium will follow the ISBE meeting in Lund and will reflect upon the synergies between the two disciplines of behavoural ecology and movement ecology. We have 6 plenary speakers from around the globe who will present talks on a variety of topics, from the role of personality in animal movement to the psychology of movement to the mechanisms of navigation. It will be a really fascinating day and you are all welcome to join in the discussions and see the talks! There is also the opportunity to present your own work at our poster session and join for a symposium dinner that evening.
For more information and registration see here: http://canmove.lu.se/node/814
We plan to submit a meeting report to Animal Migration (http://versita.com/am/).  Animal Migration is a new, international journal that publishes cutting-edge research on the biology of migratory species.  The editor of the journal, Melissa Bowlin (a CAnMove alumnus), invites symposia participants to submit additional manuscripts to the journal.  Animal Migration publishes research articles, brief communications, reviews, and commentaries on all migratory species and all aspects of migration biology, from genetics and physiology to ecosystem-level interactions between migrants and their environment.  

Have a great summer and we hope to see you there !
