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.

The ecology of river ice The ecology of river ice
Many of the world's rivers are ice-covered during winter months but increasing evidence indicates that the extent of river ice will shift substantially as winters warm. However, our knowledge of rivers during winter lags far behind that of the growing season, limiting our understanding of how ice loss will affect rivers. Physical, chemical, and biological processes change from headwaters...

Warmer winters increase the biomass of phytoplankton in a large floodplain river Warmer winters increase the biomass of phytoplankton in a large floodplain river
Winters are changing rapidly across the globe but the implications for aquatic productivity and food webs are not well understood. In addition, the degree to which winter dynamics in aquatic systems respond to large-scale climate versus ecosystem-level factors is unclear but important for understanding and managing potential changes. We used a unique winter data set from the Upper...

Land use change influences ecosystem function in headwater streams of the Lowland Amazon Basin Land use change influences ecosystem function in headwater streams of the Lowland Amazon Basin
Intensive agriculture alters headwater streams, but our understanding of its effects is limited in tropical regions where rates of agricultural expansion and intensification are currently greatest. Riparian forest protections are an important conservation tool, but whether they provide adequate protection of stream function in these areas of rapid tropical agricultural development has...

Riparian forests buffer the negative effects of cropland on macroinvertebrate diversity in lowland Amazonian streams Riparian forests buffer the negative effects of cropland on macroinvertebrate diversity in lowland Amazonian streams
Riparian forests regulate stream ecosystems and biodiversity. Therefore, changes to riparian structure may threaten stream ecosystem function by triggering taxonomic and functional changes to aquatic communities. Because macroinvertebrate assemblages are sensitive to environmental changes, they can be effective indicators of stream integrity in disturbed landscapes. To assess the role of...

Aquatic ecosystem metabolism as a tool in environmental management Aquatic ecosystem metabolism as a tool in environmental management
Recent advances in high-frequency environmental sensing and statistical approaches have greatly expanded the breadth of knowledge regarding aquatic ecosystem metabolism - the measurement and interpretation of gross primary productivity (GPP) and ecosystem respiration (ER). Aquatic scientists are poised to take advantage of widely available datasets and freely-available modeling tools to...

Agricultural land-use change alters the structure and diversity of Amazon riparian forests Agricultural land-use change alters the structure and diversity of Amazon riparian forests
Riparian forests play key roles in protecting biodiversity and water resources, making them priorities for conservation in human-dominated landscapes, but fragmentation associated with expanding tropical croplands threatens their ecological integrity. We compared the structure of tropical riparian forests within intact and cropland catchments in a region of intensive soybean production...
