Permanent ice cover by glaciers and snowfields is a dominant physical force in mountain ecosystems. From an ecological perspective, constant ice cover places harsh controls on life including cold temperature, limited nutrient availability, and often prolonged darkness due to snow cover for much of the year. Despite these limitations, glaciers, and perennial snowfields support diverse, primarily microbial communities. In a new review, postdoc in the lab Scott Hotaling and colleagues we synthesize existing knowledge of ecological stoichiometry, nutrient availability, and food webs in the mountain cryosphere (specifically glaciers and perennial snowfields).

Joanna is a co-PI on the Evolution in Changing Seas RCN and spent the week at the Synthesis Workshop at Shoals Marine Lab. It was a diverse group of marine and evolutionary biologist who are coming together to develop integrated frameworks for studying adaptation to ocean change. There is a great writeup in the Molecular Ecologist about the workshop.
Graduate student Alex Fraik started her 6 month NSF funded internship with Krista Nichols at NOAA. While most of her project will be analyzing existing datasets on fish before and after dam removal, she had a chance to participate in some fieldwork.
Joanna Kelley presented at the NHGRI Comparative Genomics Workshop in Bethesda, MD. It was a fantastic event bringing together ~115 genome biologists from around the country to discuss comparative genomics and the NHGRI strategic plan as it relates to comparative genomics. The schedule of speakers is here: https://www.genome.gov/event-calendar/perspectives-in-comparative-genomics-and-evolution

Thrilled to announce that our NSF proposal to study polar fish genome evolution has been funded!! Co-written with postdoc Scott Hotaling! The award abstract is located here: https://www.nsf.gov/awardsearch/showAward?AWD_ID=1906015
Congratulations to Scott Hotaling for receiving The Company of Biologists Travelling Fellowship! Scott will use the award to work with Katie Marshall at University of British Columbia to study thermal tolerance in ice worms!
Our paper on the genetics of glacier ice worms, which shows long-distance dispersal of ice worms is out today! The paper is in Proceedings of the Royal Society B! Birds eating ice worms may drive passive long-distance dispersal! Below is the first ever photographic proof of it, which postdoc Scott Hotaling took on Monday!
There is also a great write-up in the WSU Insider: https://news.wsu.edu/2019/06/26/unlocking-secrets-ice-worm/
We had a great visit with VPR Chris Keane and Mike Kluzik, director of the Office of Research Assurances. We talked about lab safety, laboratory challenges, and general building issues.
