Jennie Brentrup, who joined the lab in the fall of 2011, is broadly interested in studying the effects of climate change on temperate and alpine lakes. Through the use of a profiling buoy, which she helped develop, as well as experimental methods and field sampling, she's investigating spatial and temporal changes in light, dissolved organic matter (DOM) processing, and dissolved oxygen in a temperate lake in response to changes in precipitation and transparency. Jennie is part of the Global Lake Ecological Observatory Network (GLEON) and the co-chair of the GLEON student association (GSA), where she works to collaborate with scientists collecting high-frequency data from buoys in lakes around the world. She was a member of the first cohort of the GLEON fellowship program, where she gained technical and analytical skills to carry out macroscale biology and to integrate with the GLEON network. Jennie's cohort focused on examining continental scale water quality patterns across multiple spatial scales, as well as improving the understanding of metabolism model estimates at a range of temporal scales.
Rachel Pilla is PhD student analyzing long-term lake temperature data from around the world in the context of climate change and seasonal changes in abiotic factors such as water
transparency, lake temperature, dissolved oxygen, and watershed characteristics. Her research focuses on the ecological consequences of changes in lake thermal structure and the
implications for lake ecosystems and services. Rachel is also interested in the effects of lake browning due to increased dissolved organic carbon, and the potential resulting effects
on oxygen, temperature, and biota. She completed her Master's degree in the Global Change Limnology Laboratory in 2015.
Nicole began her pursuit of a Masters degree in the Global Change Limnnology Lab in Summer 2016. She is interested in the effects of lake browning on the invasibility of non-native species. Browning, or an increase in color-absorbing compounds in the water, can impact plankton communities through shading or by serving as a carbon and/or nutrient subsidy. Nicole hopes to study the ways in which these different mechanisms can facilitate the movement of invasive species into lakes with changing transparency and dissolved organic carbon inputs.
Lauren Adkins, who began working on her PhD in Fall 2016, plans to study the effects of climate change and changing transparency on lake phenology, mixing, and nutrient regeneration. Lauren is also interested in studying the public health and socioeconomic consequences of those changes on communities relying on the lake for goods and services.
