Happy New 2013!

Posted by Erik Svensson

The year 2012 is now behind us, and we are looking forward to 2013. The past year was, I dare to say, extremely successful in terms of grant applications, good publications, events and activities. To mention just a few things: three new postdocs joined the lab (Yuma, Lesley, Natsu), one PhD-student defended her thesis in May (Anna Runemark), one postdoc got a "Junior Project Grant" from the Swedish Research Council (Maren) and Jessica got a large grant from the Crafoord Foundation, that has made it possible for her to recruit a new PhD-student to work on the flatworm experimental evolution project. I myself, got a large grant from The Swedish Research Council too, which I am of course very happy for. I certainly hope that 2013 will be as successful, for all of us, as was 2012. Well done, all of you!

Among publications, I could mention some nice papers in Ecology, Molecular Ecology and Trends in Ecology & Evolution, but there are certainly more. I was also happy to get my new volume "The Adaptive Landscape in Evolutionary Biology" out at Oxford University Press (co-edited with Ryan Calsbeek from Dartmouth College, USA). 

Below are some pictures from the past year. Keep up the good work, friends!

In December, postdoc Lesley Lancaster visited Erik in Dalby to run some generalized linear models in "R" to investigate the role of temperature on mating conflicts in the polymorphic damselfly Ischnura elegans. 

Earlier in December, lab members from EXEB and other colleagues at the Evolutionary Ecology Unit went for our annual Christmas Meeting. Here John, Jasmine and Anna Nordén enjoy the Christmas Table in the evening after the talks. 

And here are Jessica and Yuma in the same evening.

In January and February, Erik went to South Africa for field work with odonates in the Western Cape Province with Master's student Anna Nordén (right) and undergraduate Johanna Eklund (left). Here they both enjoy some of the wine of the Stellenbosch district. 

The arrival of our two Japanese postdocs Yuma and Natsu in May enabled us to start up some new projects, including one on Wing Interference Patterns (WIP:s) in Drosophila melanogaster and their role in mate choice and sexual selection. Here we see Yuma, Natsu, Jessica and Jostein Kjarandsen in the lab, doing mate choice trials (Erik is behind the camera). 

Our new paper about learning in sexual selection and speciation is now out in TREE

Our paper in Trends in Ecology & Evolution about the role of learning in sexual selection and speciation is now online, and you can find a link to it here. Soon the reprints will hopefully come, and then you can ask Machteld Verzijden for a copy (machteld.verzijden@biol.lu.se). Hopefully, this paper will stimulate increased interest and more experimental and observational studies in this fast moving field.

Below, you will find more details about the paper. Enjoy!

Learning is widespread in nature, occurring in most animal taxa and in several different ecological contexts and, thus, might play a key role in evolutionary processes. Here, we review the accumulating empirical evidence for the involvement of learning in mate choice and the consequences for sexual selection and reproductive isolation. We distinguish two broad categories: learned mate preferences and learned traits under mate selection (such as bird song). We point out that the context of learning, namely how and when learning takes place, often makes a crucial difference to the predicted evolutionary outcome. Factors causing biases in learning and when one should expect the evolution of learning itself are also explored.

Merry Christmas and Happy New Year 2012!

 Another year has soon passed, and I wish to say Merry Christmas and a Happy New Year to all of you involved in research in lab. This includes both those of you who are currently in Lund, and those of you who are elsewhere in the world, such as in exotic countries like Norway and Australia.

The pictures above come from the Christmas Meeting in the new Evolutionary Ecology Unit, which was held last week. After talks in the afternoon by several group members and other colleagues in the new unit, it was time for the traditional Swedish Christmas Table, or "Julbord" As you see, Jessica Abbott participated too, after several years of exile in Canada and Uppsala. Jessica will start her new position in Lund in January 2012, after receiving her "Junior Project Grant" from Vetenskapsrådet in 2011. Tina Karlsson also participated, and she will leave to start her postdoc in Finland (Helsinkki) in May 2012.

The year 2011 was an extremely successful year for our lab, in terms of succesful grant applications. Apart from Jessica obtaining a VR-grant and Tina getting a postdoc-grant from VR, Fabrice Eroukhmanoff obtained an EU/Marie Curie postdoc in December, and Machteld Verzijden got extension on her postdoc from the Wennergren Foundation. Considering the severe competition for grants these days, I am both amazed and proud of these achievements of you guys. And you should be as well, of course.

The year 2011 was also  successful in terms of publishing, with nice papers in leading journals, such as Animal Behaviour, BMC Evolutionary Biology, Heredity, Evolution, Journal of Evolutionary Biology, to name a few. We are clearly doing work that is interesting and relevant, and I have the feeling we are moving in the right direction to be even more succesful in the coming years.

Once again: Merry Christmas and enjoy the break! See you in 2012!

Happy New Year!

I hereby wish all my co-workers (students, PhD-students, postdocs and colleagues) a Happy New Year 2011! I certainly hope that the new year will be as succesful as the previous was, for many of us. Apart from several good publications in excellent journals (BMC Evolutionary Biology, Evolution, J. Evol. Biol., TREE to mention only a few) I would also like to highlight some other great highlights (to me personally):

1. Kristina Karlsson succesfully defended her PhD in November and have already published most of her thesis-papers. Well done!

2. Fabrice Eroukhmanoff got a postdoctoral 2-year grant from The Swedish Research Council (VR) to go to Norway (Oslo University) and work with Glenn-Pether Saethre and Thomas F. Hansen.

3. Machteld Verzijden found out, just before Christmas, that she will stay in our lab for 2-3 more years, due a postdoctoral scholarship from the Wenner-Gren Foundations.

4. Former postdoc Shawn Kuchta got a faculty position at Ohio University (Athens, USA), and started up his new lab from the beginning of September 2010. Sophia Engel visited him during November, and I will myself go there for a visit in April 2011.

Needless to say: I am proud to work with such a group of excellent and dedicated scientists as you guys! Although academic life is stressful and we compete (like all other groups) for grants and to get our papers published in good journals, I think we are doing remarkably well, as a lab and as a group. I think this is because we regularly meet and discuss science - in a friendly and cooperative atmosphere. This is the key to sucess - much more than large research grants. I hope we can continue along this succesful path for many years to come.

As for myself, I will now leave for South Africa (well, tomorrow!), and will be back in the last week of January. Until then; enjoy this picture of a Greater Collared Sunbird, photographed in the Eastern Cape Province in South Africa in April this year. My overly ambitious daughter My (who is soon a professional blogger and expert in HTML-programming, by the way), has started up a new photo blog, where she wants us both to upload our photos during the trip to South Africa. You can find it here.

I am not sure I will allocate that much time as my daughter expects me to, as I want to stay away from the internet for a while, when enjoying field work, good wine, birds and wildlife. But keep following this other blog, perhaps I will change my mind :).

Lab-meeting: evolution of mate choice in swordtail fish

During the lab-meeting this coming week (Wednesday 24 March), our postdoctoral researcher Machteld Verzijden will give a presentation of the research that she performed during her previous postdoc in the laboratory of Gil Rosenthal in Texas. Machteld studied mate choice and sexual selection in swordtail fish, using some very clever video manipulations of the male sword (or rather, how females perceive the sword), and assessed the consequences in terms of mate choice and its effects of sexual selection. This will be a talk that everybody who has the slightest interest in fish, sexual selection, sensory ecology or all of these topics should come and listen to.

Also, we hope that our colleagues from the "Vision Group", Almut Kelber and Miriam Henze, will also join us for this lab-meeting to listen to this fascinating talk. I hope that we will have some very good scientific discussions about the fascinating intersection between sexual selection and sensory ecology. Everybody should be most welcome!

When: Wednesday, March 24, 10.15
Where: "Darwin-room", 2nd floor, Ecology Building

Any fika-volunteer???

A new postdoctoral co-worker: Welcome Machteld Verzijden!

I am pleased to announce that our laboratory will get another postdoc from 2010: Machteld Verzijden was awarded a postdoctoral grant from The Swedish Research Council (VR) this spring. Her research interests are focussed on animal behaviour, in particular animal communication systems and the role of learned mate preferences in sexual selection and speciation.

Machteld has previous research experience from birds (zebra finches) and fish (African mouthbrooding cichlids). It is a very talented young scientist that will soon join our laboratory, with some recent interesting and impressive publications in journals like Current Biology and Evolution. In Lund, Mactheld will study the mechanisms of mate preference learning in Calopteryx- damselflies, which will fit well in to our past and ongoing studies about the interplay between gene flow, sexual isolation and plasticity in mate preferences in these insects.

Machteld received her Ph.D. from Leiden University under the supervision of Prof. Carel Ten Cate. During her Ph.D., she did experimental work on the role of social learning in adult mate preferences in cichlid fish, as well as population genetic modelling work together with Prof. Maria Servedio, a leading theoretical evolutionary biologist. Currently, she is on her first postdoctoral stay in Texas, working on sexual selection and communication in fish in the laboratory of Prof. Gill Rosenthal. Machteld will thus bring some new insights and perspectives from her background in ethology and animal psychology, which will nicely complement the general ecological and population genetic focus of our current research.

As an aside, I note that I have been lucky to have been able to recruit so many good co-workers that have been so succesful in obtaining postdoctoral grants from VR: apart from Machteld, also Maren Wellenreuther, Thomas Gosden and Jessica Abbott have been succesful in obtaining these highly attractive and competitive postdoctoral grants. Although I cannot take much credit for Mactheld and Marens past achievements in any respect, given that their Ph.D.:s were obtained in other laboratories than mine, I sincerely hope that we will be equally succesful in the future. I also find it interesting that Machteld is my second "fish-postdoc" (the first one was Maren). I have yet to publish my first fish paper (if it will ever happen), and it is nice with people who are brave to switch study organisms. It is also, most likely, a good career move.
