Kathi Jo Jankowski, PhD
Kathi Jo Jankowski is the Principal Investigator for the Water Quality Component of the Upper Mississippi River Restoration Program's Long-term Resource Monitoring Element.
She coordinates water quality monitoring and research on the Upper Mississippi in coordination with several federal and state agencies. Her research aims to provide understanding on how aquatic ecosystems are responding to ongoing environmental change. Her work focuses on understanding nutrients, biogeochemical processes, and productivity in the Upper Mississippi and other river ecosystems globally.

Continuous water quality sensor data from the main channel and a backwater of the Upper Mississippi River from 2015-2018 Continuous water quality sensor data from the main channel and a backwater of the Upper Mississippi River from 2015-2018
This dataset includes high-frequency sensor data collected during four consecutive summers from buoys deployed at main channel and backwater sites in Pool 8 of the Upper Mississippi River from 2015-2018. It also includes the event-specific concentration-discharge metrics (hysteresis and slope) calculated by combining the water quality sensor data with discharge data from a nearby USGS...
Land cover, discharge, terrestrial litterfall, organic matter, and nutrient concentrations of headwater streams in Mato Grosso, Brazil Land cover, discharge, terrestrial litterfall, organic matter, and nutrient concentrations of headwater streams in Mato Grosso, Brazil
These data were collected as part of a study headwater streams of the lowland Brazilian Amazon to assess the effects of land use change on organic matter dynamics (OM), ecosystem metabolism, and nutrient concentrations and uptake (nitrate and phosphate) in 11 first order streams draining forested (n=4) or cropland (n=7) water-sheds with intact riparian forests. Data included here are...

Establishing fluvial silicon regimes and their stability across the Northern Hemisphere Establishing fluvial silicon regimes and their stability across the Northern Hemisphere
Fluvial silicon (Si) plays a critical role in controlling primary production, water quality, and carbon sequestration through supporting freshwater and marine diatom communities. Geological, biogeochemical, and hydrological processes, as well as climate and land use, dictate the amount of Si exported by streams. Understanding Si regimes—the seasonal patterns of Si concentrations—can help...

Intrinsic and extrinsic regulation of water clarity in a large, floodplain-river ecosystem Intrinsic and extrinsic regulation of water clarity in a large, floodplain-river ecosystem
Ecosystem processes in rivers are thought to be controlled more by extrinsic than intrinsic factors, that is, the result of processes that occur upstream or within their watersheds. However, large floodplain rivers have a diverse assemblage of aquatic areas spanning gradients of connectivity with the main channel and internal controls may at times regulate long-term dynamics. When and...

Bridging the gap between mathematical biology and undergraduate education using applicable natural resource modeling Bridging the gap between mathematical biology and undergraduate education using applicable natural resource modeling
Mathematical biology is a wide field of study with many venues that undergraduate students can access through research. However, the topics of study for these students can be overwhelming, and many topics of study yield either only trivial results or abstract outcomes that are nonintuitive and diffcult to understand. We have used natural resource modeling, and more specifically, a...

Long-term changes in concentrations and yield of riverine dissolved silicon from the poles to the tropics Long-term changes in concentrations and yield of riverine dissolved silicon from the poles to the tropics
Riverine exports of silicon (Si) influence global carbon cycling through the growth of marine diatoms, which account for ∼25% of global primary production. Climate change will likely alter river Si exports in biome-specific ways due to interacting shifts in chemical weathering rates, hydrologic connectivity, and metabolic processes in aquatic and terrestrial systems. Nonetheless, factors...

Intraspecific trait variability facilitates tree species persistence along riparian forest edges in Southern Amazonia Intraspecific trait variability facilitates tree species persistence along riparian forest edges in Southern Amazonia
Tropical forest fragmentation from agricultural expansion alters the microclimatic conditions of the remaining forests, with effects on vegetation structure and function. However, little is known about how the functional trait variability within and among tree species in fragmented landscapes influence and facilitate species’ persistence in these new environmental conditions. Here, we...

River geomorphology affects biogeochemical responses to hydrologic events in a large river ecosystem River geomorphology affects biogeochemical responses to hydrologic events in a large river ecosystem
Shifts in the frequency and intensity of high discharge events due to climate change may have important consequences for the hydrology and biogeochemistry of rivers. However, our understanding of event-scale biogeochemical dynamics in large rivers lags that of small streams. To fill this gap, we used high-frequency sensor data collected during four consecutive summers from a main channel...
