desperately seeking puffins!

cliffOn Sunday afternoon, I made a brief trip to the southern coast of the Reykjanes Peninsula in an attempt to watch puffins. According to my guide book, the cliffs at Krýsuvíkurberg were populated with many species of birdlife, including the elusive puffin. However, I could only spot gulls, and more gulls, as I walked a few kilometres along those cliffs and away from the occasional 4WDcliff2 stopping by the end of a dirt road [my small rental car could not handle that far]. When I was about to turn back, I spotted different birds on a small rock promontory, too far for me to tell the species, and as I was zooming at them, a puffin flew by!, so small that I almost missed it. I tried to see if any other was dwelling in the cliffs left and right but to no avail. A few minutes later, presumably the same puffin flew back and this was the end of it. Even after looking at the enlarged picture, I cannot tell what those “other” birds are: presumably Brünnich’s guillemots…

capture mark recapture with no mark and no recapture [aka 23andmyfish]

moonA very exciting talk today at NBBC15 here in Reykjavik was delivered by Mark Bravington yesterday on Close-kin mark recapture by modern magic (!). Although Mark is from Australia, being a Hobart resident does qualify him for the Nordic branch of the conference! The exciting idea is to use genetic markers to link catches in a (fish) population as being related as parent-offspring or as siblings. This sounds like science-fantasy when you first hear of it!, but it is actually working better than standard capture-mark-recapture methods for populations of a certain size (so that the chances to find related animals are not the absolute zero!, as, e.g., krill populations). The talk was focussed on bluefin tuna, whose survival is unlikely under the current fishing pressure… Among the advantages, a much more limited impact of the capture on the animal, since only a small amount of genetic material is needed, no tag loss, tag destruction by hunters, or tag impact of the animal survival, no recapture, a unique identification of each animal, and the potential for a detailed amount of information through the genetic record. Ideally, the entire sample could lead to a reconstruction of its genealogy all the way to the common ancestor, a wee bit like what 23andme proposes for humans, but this remains at the science-fantasy level given what is currently know about the fish species genomes.

visiting deCODE [Íslensk erfðagreining]

Tonight, we [participants to the NBBC15 conference] got invited [and bused] to deCODE, the Icelandic genetic company that has worked on the human genome since 1996, taking advantage of the uniquely homogeneous features of the Icelandic population. Which overwhelmingly descends from the few originals settlers to populate Iceland in the late 800’s.  deCODE is located in downtown Reyjavik next to the regional airport and to Hallgrímskirkja, the iconic church overlooking the city. The genetic company has gathered genotypic and phenotypic information about half the population of Iceland and, thanks to extensive genealogical sources, has also put together the Íslendingabók that covers the entire current population and runs back to the origins of the country. Despite being a company (and now a subsidiary of Amgen), deCODE appears to operate just like another research institution, searching for genetic explanations of diseases and genotyping more and more individuals towards that goal, with a startup atmosphere in a well-designed building… A most unusual and enjoyable evening at a conference! Making me wonder if they have visiting positions…
