- 요약Shallow lakes and ponds are dynamic ecosystems that are common features in urbanized landscapes. These systems are especially complex in urban and human-impacted landscapes, where nutrient loading, altered hydrology, and ecosystem management practices interact with natural drivers of biogeochemical processes. Knowledge gaps in our understanding of winter dynamics and the rarity of long-term datasets inspired the following dissertation research on the ecological and biogeochemical dynamics of shallow urban ponds and lakes. Chapter 1, I characterize the under-ice oxygen and greenhouse gas dynamics of 20 urban ponds to understand how productivity, ice conditions, and antecedent summer characteristics shape winter biogeochemistry. By focusing on the less-studied winter season, this chapter highlights the importance of year-round monitoring in small, urban waterbodies. Chapter 2 used long-term datasets to investigate ecological state change in Lake Wingra, a shallow, eutrophic lake that underwent biomanipulation to reduce common carp populations. I ask whether this single intervention led to a lasting shift from an algal to macrophyte-dominated state, and explore the mechanisms underlying persistence, including changes in nutrient dynamics and primary producer communities. This chapter contributes to the broader understanding of ecosystem stability, feedbacks, and management outcomes in shallow lakes. Chapter 3 focuses on spatial and seasonal variability in CO2 concentrations and fluxes within a macrophyte-dominated, shallow lake. I provide new insights into how aquatic vegetation, ice cover, and seasonal productivity shape lake-level carbon dynamics. Together, these chapters advance our understanding of shallow, human-impacted aquatic systems by providing novel empirical data and long-term perspectives on their structure and function. By integrating season, spatial, and temporal dynamics, this work contributes to our understanding of how urban waterbodies might respond to changing climate, and how that might influence water quality.
