The Dimensions team got together for an exciting All Hands Meeting in Grand Haven MI last week – we had a chance to both find out how much progress has been made and converge on new ideas for synthesizing our results, in ways we had not previously imagined. Hooray for collaboration!

The Michigan State University team has successfully cultured a number of Baikal species, including the finicky little diva Aulacoseira baicalensis! [knock on wood] Getting this beauty into culture aids not only MSU experimentation that characterizes functional diversity, but also the genetic work on Baikal endemics at University of Texas. Our Russian colleague Kirill is in residence with the MSU team right now, supported by a prestigious Russian fellowship, and he has been busy isolating phytoplankton for cultures and otherwise making progress in research towards his dissertation at Irkutsk State University in Siberia. From nutrient and temperature experiments to transcriptomics and theoretical modeling, the MSU team is working in high gear, with active collaborations across all of the universities.
Ted and Marianne at Wellesley have just about finished up the functional diversity zooplankton experiments (e.g., “eggsperiments“) that will help to parameterize theoretical models, and relate to zooplankton genetic characterizations at East Tennessee State University. Ted has also been busy pulling together all the pieces of the Saprolegnia parasitism story that began two summers ago at the lake – the prevalence of Saprolegnia infections on Epischura caught us a bit offguard at the time and then turned into a project in which we all found ways to lend expertise – genetics of Saprolegnia, mortality experiments, theoretical modeling, and statistical analysis of long-term data. If we would all stop suggesting new, cool things that we need to do with Saprolegnia, Ted might have a chance to get that paper together!

Naturally, Wellesley College stole the show when they told us about the preliminary results of studying the biogeochemical records preserved in the archived teeth of Baikal seals (!) with seal experts at Irkutsk State University – Ted promises he is going to write a blog post about it so I won’t steal his thunder here… Ted seems awfully busy wrapping up manuscripts, so that he can move on to a new faculty job at the Large Lakes Observatory at University of Minnesota-Duluth – congratulations, Ted!

At UT-Austin, Mariska and Ed have been buried in lab work to do the genetic characterizations of Baikal algae, for many months, and are expecting the results back any day now. Stay tuned…
Larry successfully defended his Masters thesis and participated in his commencement at ETSU the day before arriving at the All Hands Meeting. Not only was he an active GK-12 Fellow at ETSU, teaching kindergarteners but he also did field work in Russia and the lab work to show us that there appears to be genetic differentiation among Epischura across basins. Larry is now madly writing this up for peer review, and wrapping up other Baikal projects, so that he can move on to his next adventure – a Ph.D. program at Yale with David Post – congratulations, Larry!
Kara, Steve and I recently moved from UC-Santa Barbara (NCEAS) to Washington State University. Luckily, since we focus on mainly data, data, data… the move has not put us too far behind in our Baikal work! Together with our Siberian colleagues Lyubov, Kirill and Zhenya, and the rest of the Dimensions team, we are working out some of the main drivers of “melosira years” in Lake Baikal, a long-standing mystery – why in some years does Aulacoseira (Melosira) have massive under-ice blooms, and in other years it does not? Ice is mysterious stuff…

The circumbaikal cruise in 2013 has yielded a ton of data that we are excited to be bringing together. Our ISU colleagues have many years of data from stations throughout the lake that provide a great context for the 2013 distributed sampling of plankton and other limnological variables. We are also looking forward to comparing notes with our colleagues from University of Nottingham and University College London who have been working across all basins of the lake in the past several years as well!
At the lake last year, Ed drew up this planning map for our circumBaikal cruise – the map brought back very fond memories when he showed it at our All Hands Meeting – we were lucky with the weather and achieved even better spatial coverage than we originally planned using this map!

Putting the pieces together – from genetic to taxonomic and functional diversity – is now becoming a reality, and this revelation at the All Hands Meeting was very energizing for us all. Science is never enough, of course, and some team-building activities (aka karaoke) provided the extra edge that all collaborative groups need in order to achieve the highest levels of creativity!
The MSU team and The Intrepid Kara Woo arranged a number of the travel logistics, including bringing a coffee grinder and a french press to keep us well supplied with delicious coffee – for which we are all extremely grateful! Of course, no one but Lev could be responsible for logistics which resulted in him and Larry arriving by ferry across Lake Michigan in the early morning – they are the only ones who will ever know the full accounting of red-eye planes, trains, boats and automobiles… Regardless of those mysterious details, we were delighted to see Lev arrive on the ferry holding a plankton net aloft… and they both jumped right into talking good science for several intense days!
