There is a new lab publication in Biogeochemistry available online now! Carla and Brian are both authors along with Dr. YueHan Lu from the Geology Dept at UA. This paper describes particulate and dissolved organic materials and nutrient concentrations in an unmodified river, the nearby Sipsey River. The Sipsey has a broad floodplain that acts as a source of DOM to downstream reaches while also disrupting the movement of particulate materials downstream from the headwaters. We hope this serves as a base for studies into this uniquely unmodified river and its associated floodplain!
We now have a Seal AQ300 to conduct water chemistry analysis. The instrument got setup and the whole lab participated in the training last week. It's going to get a lot of use and we were glad that Seal sent someone to train us. So many water samples to come!
In collaboration with John Pfeiffer and others, a paper highlighting a fifth Ambleminae tribe that occurs in Mesoamerica has just been published in Zoologica Scripta! This work better classifies the diversity in this group. However, there is still a knowledge gap remaining. It was also a great deal of fun putting this work together with John and collecting the animals in Usumacinta River with Krista Capps!
The upcoming Dimensions of Biodiversity project was in the news today! The official press release from NSF came out today to announce the awarded projects: http://bit.ly/2O6Lwva
Carla acted as a co-author on Garrett Hopper's (Kansas State grad student) paper, "Biomass distribution of fishes and mussels mediates spatial and temporal heterogeneity in nutrient cycling in streams". Nice work Garrett! This is work funded by NSF and follows up on some of Carla's PhD work. See the paper here: https://rdcu.be/9IW9
Atkapps Exchange, a inter-lab exchange between the Atkinson and Capps lab, was held this past weekend at the Jones Ecological Research Center at Ichauway. We had an afternoon of short "ignite-style" talks followed by a swimming and snorkeling trip on Friday. On Saturday, Jennifer Howze gave a field talk on gopher tortoises and then we had the privilege of floating Ichawaynochaway Creek! Carla, Hal Halvorson, Brian, and Monica all visited a couple of wetlands and collected crayfish for an upcoming experiment. Overall, a very fun and productive weekend!
We made it through the first 3 days of the semester! The first lab meeting was held today and several things are in works in the Atkinson lab. Glad to have a lot of hands available for getting through samples and several minds for digging through data and discussing results. Think its going to be a great semester! Dan made it fun by bringing an alligator snapping turtle along (this may have not actually happened)!
There is a new paper out from the lab in collaboration with Lora Smith, Amanda Subalusky, Julia Earl, David Mushet, David Scott, Stacey Lance, and Steve Johnson! The manuscript is an overview of the abiotic and biotic factors driving biological connectivity between seasonal wetlands and other landscape features. Check it out here: https://rdcu.be/47iR!

My life is like a float trip!
