Screenshot of ArcGIS story map landing page with inset image of author Carla Lopez Lloreda. Carla López Lloreda is a PhD student from Puerto Rico in the Hotchkiss lab. Her dissertation research focuses on quantifying and understanding greenhouse gas emissions from wetlands, as well as how controls on wetland greenhouse gas emissions vary among different global regions. Recently, Carla published an ArcGIS story map on sustainable resource management in Puerto Rico in the aftermath of Hurricane Maria in 2017. The story highlights community-based efforts to improve resource management, inspired by hurricane damage which exacerbated ongoing long-term environmental degradation. Congratulations, Carla, on this accomplishment!

Stream team Ph.D. students Abby Lewis (Carey Lab), Grace O'Malley (Mims Lab), and Carla López Lloreda (Hotchkiss lab) are co-authors on a new paper, published this week in the Journal of STEM outreach. The paper describes the development of a Flipped Science Fair outreach program, where children judged graduate student science fair posters. Other stream team graduate students participated in the event last year as presenters and organizers, helping make the event a success! Congrats, all!
Tyler Allen, master's student in Dr. Austin Gray's lab presented his poster entitled, “A comparative assessment of green product toxicity: What are the potential effects when released into the environment?” At this year Society for Freshwater Sciences Meeting in Brisbane, Australia and won won Best Poster Presentation in Applied Research! Congrats Tyler.
Stream Team students from Drs. Hotchkiss, Entrekin, and Gray respective labs were selected to join the Society for Freshwater Sciences Emerge Program. Emerge is an National Science Foundation supported program to help students from underrepresented communities develop a sense of belonging within a scientific community. Congrats to you three!

Carla López Lloreda co-authors article on greenhouse gas dynamics in Puerto Rican streams12/20/2022 Congratulations to Carla and co-authors! Please check out the publication here. Briefly, from the abstract: "We use a five-year record of weekly water chemistry and dissolved gas data from eight tropical watersheds of varying lithology and redox conditions in the Luquillo Mountains of Puerto Rico to examine controls on GHG variability and estimate gas flux. Streams were frequently supersaturated in all three gases indicating that streams in this tropical landscape are sources of GHGs to the atmosphere. Concentrations of CO2 and N2O were associated with lateral inputs from the surrounding landscape, whereas CH4 concentrations correlated with in-stream oxygen availability and lithology."

Carla is a graduate student in the Hotchkiss Lab; find more Hotchkiss Lab news and updates anytime on the lab website! Cameron Braswell, masters student in Drs. Austin Gray and Bryan Brown lab, presented his research at the 43rd SETAC North America Meeting in Pittsburgh and in Winston-Salem, NC. Cameron's work with Dr. Gray focuses on the impact of microplastics on crayfish and their symbiotic relationship with annelids. Cameron placed 3rd for Best Masters Student Poster Presentation at SETAC and won Best Poster presentation at ASB. Pictures also includes Gray lab members Kathleen Mayer (Ph.D. student), Tyler Allen (Masters student), and Dr. Austin Gray.
Katie is a first year PhD student in Dr. Austin Gray’s aquatic toxicology lab in the Department of Biological Sciences. She is interested in emerging contaminants of concern in freshwater ecosystems. She studies freshwater mussels and their biodetoxification process, and how that interacts with inorganic and organic particulates.
Established to honor the late William Walker, the founding director of the Virginia Water Resources Research Center, this award has been given since 1999 to recognize and support graduate students in water resources who are pursuing work in a field different from their undergraduate study, or who have returned to school following a period of professional work. Grace O'Malley (Mims lab) poses with the Stream Team exhibit at the Virginia Tech Science Festival on Saturday, Nov. 12. Stream Team graduate students and postdocs organized an aquatic science exhibit at the Virginia Tech Science Festival on Nov. 12, 2022. The festival is an opportunity for grade school students across the state to learn more about a variety of scientific disciplines. Stream Team's exhibit included a watershed runoff simulation and opportunities for festival attendees to observe zooplankton and macroinvertebrates using a dissection microscope. Stream Team volunteers included: Dexter Howard, Abby Lewis, Carla López Lloreda, Freya Olsson, Grace O'Malley, Katherine Pérez Rivera, Sergio Sabat-Bonilla, and Whitney Woelmer. Carla López Lloreda (Hotchkiss lab) teaches festival attendees about amphipods. Dexter Howard (Carey Lab) demonstrates a watershed runoff simulation. Whitney Woelmer (left; Carey Lab) and Katherine Pérez Rivera (right; Hotchkiss Lab) interact with festival attendees. Freya Olsson (Carey Lab) guides a festival guest in using a dissection microscope to look at benthic macroinvertebrates. 2022-11-02 Members of the Carey Lab pose for a photo on Lake George, NY during the 2022 Global Lake Ecological Observatory Network (GLEON) conference. Stream Team PI Cayelan Carey and several members of her lab group attended the Global Lake Ecological Observatory Network) GLEON annual meeting in upstate New York from Oct. 30 - Nov. 4, 2022. GLEON is a global grassroots network of lake scientists and GLEON annual meetings are working meetings, where researchers come together to develop collaborative projects using shared data. Working groups and projects are identified during the conference and then groups continue to meet to work on projects throughout the year. GLEON is especially welcoming to early career researchers (ECR) and provides ample opportunities for ECR to champion projects and take on leadership roles within the network. Stream Team graduate students Dexter Howard, Abby Lewis, Heather Wander, and Whitney Woelmer, postdocs Freya Olsson and Mary Lofton, and Cayelan all presented posters at the conference, and Cayelan, Freya, and Mary also ran a workshop to help GLEON members learn and teach ecological forecasting.
