Flightless rails at the NHMUK

I am delighted to say that next step on my academic journey will take me to the Natural History Museum in London/Tring, UK, for a two-year project with the somewhat pompous title The genomic underpinnings of convergent evolution: Repeated loss of flight in island rails, the greatest avian colonizers. Starting this fall, I will be hosted by Alex Bond, Senior Curator in Charge of the amazing bird collections, and I will collaborate closely with Jaime Chaves at SFSU.

This project is made possible by the European Union, who has awarded me a Marie Skłodowska Curie fellowship.

Ornis Svecica fledges again

When I joined the editorial board of BirdLife Sweden‘s peer-reviewed ornithological journal Ornis Svecica in 2017, I had quite a few ideas of things that I thought could be improved. The journal has been published since 1991, and caters to academic researchers as well as non-professional ornithologists. It is a great resource with no publishing or article processing fees, but very little had changed since the founding of the journal. Late last year, the publisher made the decision to stop printing the journal, which forced a kick-start overhaul in order to find a new solution for the journal, where all material could be easily accessible online. I was glad to be appointed Managing Editor, and since then I have worked hard together with Editor-in-Chief Sören Svensson and the rest of the editorial board to achieve this goal. I am therefore pleased to say that Ornis Svecica relaunches as an open access, no fees, online only journal on the World Migratory Bird Day, May 11, 2019. Check out the site at http://os.birdlife.se, learn something about the foraging prerequisites of Ortolan Buntings or the range expansion of European Stonechats and see what you think of the new graphic profile, and read some more of my thoughts in this editorial. Any new articles will be published shortly after acceptance in a continuous publication model. I hope you will enjoy – and I hope you’ll consider submitting a contribution!

How did the world’s smallest flightless bird end up on Inaccessible Island?

We recently published a paper in Molecular Phylogenetics and Evolution on the origin and taxonomy of the Inaccessible Island Rail Atlantisia rogersi. The paper is available, with free access to anyone, until December 7, via this link. I summarized our findings in a Twitter thread, that I will share here.

How can we make fieldwork less dangerous?

In June, I participated in the excellent workshop for Evolutionary Quantitative Genetics, generously supported by the Society for the Study of Evolution (SSE). During a lecture Brian O’Meara mentioned Richard Conniff’s the Wall of the Dead, or the Memorial of Fallen Naturalists, and I just couldn’t let go of it. Reading the entries at the Wall of the Dead, I started wondering if certain fields of study were over-represented. It turned out that Talia Yuki Moore was also wondering things, and would like to draw conclusions from the tragic incidents in order to prevent future field work casualties.

We thus joined efforts, and contacted Richard Conniff about analyzing the material to better understand the circumstances and causes of scientist mortality during fieldwork. However, Conniff’s Wall of the Dead certainly is not exhaustive, and we are now therefore making a call for more information. Do you know of someone who is missing from this list? If so, please add their information to our database. Your contribution will help establish new safety standards for fieldwork and memorialize the contributions of those who gave their lives to further our understanding of the natural world.

Please contribute your information to our form, where you can also read more about the study, which is an IRB exempt study registered with the University of Michigan Institutional Review Board (#HUM00149801). We will forward all new entries to Richard Conniff’s Wall of the Dead. We will also account for all entries in upcoming publications, whether they will be included in our analyses or not (depending on whether they match certain criteria).

Also, please forward this call for information widely. If you have any questions, do not hesitate to contact me or Talia (taliaym /at umich.edu).

I, an Oregonian fish researcher

How did this happen to a bird researcher from Sweden? Well, evolutionary questions can be addressed in various study systems, and I will make use of the crazy syngnathid fish (seahorses, pipefish, and seadragons) to look into craniofacial development and evolution. I am happy to do this in the Cresko Lab at the Institute of Ecology and Evolution, University of Oregon. I started my three-year postdoc project in August 2017.

The world’s largest canary hits the press

Our paper on the São Tomé grosbeak, summarized here and on the BOU blog, was finally published in the July issue of Ibis. This has rendered quite some interest in the press, with articles in National Geographic (Spain & Portugal), New Scientist, Science Daily, among many others. See the full list of articles in English, Spanish, Portuguese, and Swedish, with links to most of them. Surprisingly (?), all this attention means that the short note in Ibis has climbed to the top 0.5% of the most highlighted research outputs that Altmetric tracks!

Our paper is dubbed a Classic!

Google Scholar has released a new feature that lists “Classic Papers: Articles That Have Stood The Test of Time”. I am very pleased to see that a paper that I was happy to co-author with late Niclas Jonzén is among the classics, as the fourth most cited publication about birds published in 2006.

In 2005 I published my first ever peer reviewed paper, which was an analysis of long-term bird ringing data from Ottenby Bird Observatory. The 2006 Science paper was, in some sense, triggered or inspired by this work, and here we expanded and used bird ringing data several Scandinavian bird observatories, in combination with data from Capri in Italy. We could show that migratory birds that spend their winter south of the Sahara responded even more strongly to the European winter weather (which determines the progression of the following spring), than did short-distance migrants. So after a cold and dry winter, spring came later, and migratory birds arrived later.

We already knew that the birds arrived later at the Scandinavian breeding grounds, but in this paper, we made use of the data from Capri, as we argued that the arrival to Italy should reflect the departure from sub-Saharan Africa. The rationale for this is that there isn’t much opportunity to spend time between the two regions, as the birds have to cross two major barriers – the Sahara desert and the Mediterranean Sea. Furthermore, even after accounting for the winter weather, there was a clear trend over time towards earlier arrival, which we argued reflects natural selection for earlier spring migration.

The enigmatic São Tomé grosbeak is a giant seedeater

We have finally published the first piece of the puzzle about the critically endangered São Tomé grosbeak Neospiza concolor in the ornithological journal Ibis. So what is special about the São Tomé grosbeak? Pretty much everything:

  • It is among the rarest species on Earth
  • It was not seen for over 100 years
  • Taxonomists have fought about what kind of bird it really is

In 1888, the Portuguese naturalist Francisco Newton collected a specimen of an unknown bird species on São Tomé. Two years later, he found another two specimens, and with its large size and massive bill it was originally described as a weaver (family Ploceidae). However, not everyone agreed, and there was an argument about whether it was really a weaver or a finch (family Fringillidae). Eventually, most authorities agreed that it was probably a finch, but its affinities were unclear and it was rewarded its own genus, Neospiza – the new finch.

A rare sighting! This female São Tomé grosbeak (Neospiza concolor) was photographed during our field work on São Tomé, in July 2011. Photo (c): August Thomasson (augustthomasson.weebly.com).

The type specimen is held at the Natural History Museum ornithology collections in Tring, whereas the two others were destroyed in a fire in 1978 at the National Museum of Natural History in Lisbon. After Newton’s initial collections, the São Tomé grosbeak was not sighted again for over 100 years, until it was found by Dave Sergeant three other birders in 1991! Even after its rediscovery, sightings remain very scarce. Until recently, the official population size estimate has been less than 50 individuals, but recent censusing efforts by Ricardo de Lima and colleagues suggest that it might not be just that bad.

Awarded a three-year postdoc!

I am very happy to announce that last week the Swedish Research Council awarded me a SEK 3,150,000 grant to do a three-year postdoc in the Cresko Lab at the Institute of Ecology and Evolution, University of Oregon. I will dive into the world of syngnathid fish and explore the development and the evolution of the snouts of pipefish and seahorses, learning a whole bunch of new methods along the way. I very much look forward to joining Bill and his lab in 2017! I also look forward to seeing the efforts of Bill and colleagues turn into reality, with UO’s recently presented plans for the new Knight Campus for Accelerating Scientific Impact. Check out the presentation, featuring Bill and others.
