We are excited to announce our special session dedicated to nitrogen fixation at the upcoming Joint Aquatic Sciences Meeting in Portland, OR this May. Our goal is to bring together a diverse group of aquatic scientists working across a range of ecosystem types and scales. Rate measurements, gene expression, modeling all welcome! Please find our session description below as well as the link to the abstract submission site. Dont hesitate to contact us if you have any questions. We look forward to seeing you in Portland. Best, Thad Scott , University of Arkansas [email protected]

Session Description: 024 - We've got a nitrogen fixation! Exploring, integrating, and understanding N fixation along the freshwater to marine continuum New techniques and perspectives have revealed that nitrogen fixation is an important, previously underestimated, source of oceanic N. However, our understanding of this process across the freshwater to marine continuum remains limited. The more we study wetland, lake, stream, river and coastal habitats, the more we find measurable and ecologically relevant rates of nitrogen fixation. Yet many key questions remain regarding the role of biological nitrogen fixation in these environments. The goal of the session is to initiate a dialogue among scientists interested in nitrogen fixation at any level of biological organization from genes to ecosystems. We will focus on any inland water and shallow marine habitats with the goal of integrating nitrogen fixation more firmly into our understanding of nitrogen cycling across aquatic ecosystems at local and global scales. We have a range of specific interests including: 1) determining how measurement methodologies and the spatial distribution and intensity of measurements have limited our understanding of nitrogen fixation, 2) placing key findings into a global nutrient cycling framework, 3) identifying critical next steps in research and conceptual development, and 4) evaluating how more accurate estimates of nitrogen fixation may our change understanding of the ecology and biogeochemistry of aquatic ecosystems.
