    still recall with amazing clarity almost every day I was there Not only did I make some lasting friendships but I also learned so much that I want to share with my students One of the most common thing that people at Toolik said to me was I wish that my teacher had done something like this when I was in school The primary goal of my involvement with PolarTREC has always been to bring my experiences back to my classroom but hearing all Read Journal 26 July 2013 The End of an Experiment 3 Years in the Making When I accepted the post as PolarTREC teacher to scientist extraordinaire Amanda Koltz I didn t realize that this would be her last field season before publishing her dissertation Amanda began her field research on the Arctic Wolf Spider about 3 years ago and has returned to Toolik every summer since collecting data Not only is Amanda ending her research on wolf spiders arctic food webs and their connection to climate change but she is also ending her time on the Alaskan tundra I can only imagine how difficult this must be for her I was only there for 1 Read Journal 23 July 2013 Who Doesn t Love a Good Parasite Parasites the ultimate lifestyle choice As mentioned in a previous journal every organism has a place in the complex food webs of life be it an autotroph heterotroph that s us unless some human has mutated and can now photosynthesize or decomposer Ecosystems have other relationships beyond feeding ones sometimes referred to as symbiotic relationships Some of these you ve heard of like the mutualistic relationship between the anemone and the clown fish think of Finding Nemo and some of these you haven t like the commensalistic relationship between cattle and cattle egrets Read Journal 19 July 2013 How Cute are Collembolans Just What do Spiders Eat In a previous journal I mentioned that the wolf spider is a generalist predator that feeds on detritivores in the soil There are many different organisms that fall under the category of detritivore but by far the cutest that s right I said cutest are the collembolans Slugs not cute Collembolans Cute I mean honestly How cute is this guy Image from bugguide net Collecting Collembolans Collembolans are small REALLY small Sometimes you can see them walking around the soil but generally you can t unless you look very closely they are Read Journal 17 July 2013 Meet the Berlese Funnel and take a trip to the Arctic Ocean Berlesing means buckets lots and lots of buckets In my last post I explained how soil samples were taken from the tundra The samples were cut out of each of our plots with a bread knife then sectioned into surface and below ground pieces packed in a Ziploc and carted back to our lab in our packs We had 60 samples and most were water logged let s just say they weren t

    to get at least some of them down here In reflecting back on the expedition I see that so many thoughts and ideas were developed that I already think of this adventure as a beginning rather than having ended However I do need to bring closure to this set of journal entries Thank you so much to PolarTREC for providing the tools Read Journal 16 June 2013 Farewell to Finland It is time for this adventure to close I walked up Puksa behind the research station this morning for one last look out across Kevo Lake and the fells of the Utsjoki Valley This really has been a fantastic place to live and learn and I am sorry to leave I feel I am leaving lots of new friends to stay in touch with A favorite view looking out from Puksa across the Research Station Peninsula to Kevo Lake But One Last Stop However I am off to visit a friend in Tromso Norway before heading back to Fairbanks After Elina helped me with some Internet bus research Kim took me Read Journal 15 June 2013 Litterbag Science Today is my last day at Kevo Yesterday I had to say goodbye to the Petsikko Wetlands We had a blast out there under a beautifully blue sky with enough cooling breeze to keep most of the bugs at bay You just can t ask for more than that One of the things I have learned heaps about while out here is how important soil microbes are Not only are they important for the ecological role they play decomposing dead stuff but I now understand that at least from wetlands they are responsible for emitting greenhouse gasses The Junior High School science textbooks I have used to support Read Journal 14 June 2013 The Experiment The gas measurements we have been doing since I arrived are providing the control gas fluxes for Kim s experiment Later in the summer Kim will be adding chemicals to half of the collars in an effort to gain more insight into what controls methane flux in Arctic wetlands Arctic Wetland Topography An Arctic wetland is by no means homogenous or static Petsikko can be called a patterned mire It contains depressions that are very wet and raised areas that are relatively dry and so support different vegetation Petsikko can be called a patterned mire The raised areas support Read Journal 13 June 2013 Data and More Data Collecting data the field work is the fun stuff That s all well and good but at some point you have to sit down and figure out what story your data is telling you Kim and I were able to sit down together these past two days so she could show me how to turn the data that comes out of the gas chromatograph into something meaningful In the beginning Kim set up some practice files for me so I was able to load the real data from the
