Urban stream syndrome is described as the deterioration of stream health in an urbanized watershed and is associated with the loss of ecosystem services, which in turn degrades downstream environments. One key symptom of the urban stream syndrome is reduced processing of inorganic nitrogen. Previous research suggests that as urbanization increases and water quality decreases, the uptake length (Sw) of inorganic N increases. This indicates that the stream is increasing the export of N downstream compared to in situ incorporation of N into the ecosystem. We measured uptake length (Sw) of NO3, using a pulse addition method, along 9 different …
Landscape Features That Predict The Occurrence Of Shorebirds In Agriculture Fields During Migration In The Rainwater Basin, Nebraska, Lindsay Ann Brown
Landscape Features That Predict The Occurrence Of Shorebirds In Agriculture Fields During Migration In The Rainwater Basin, Nebraska, Lindsay Ann Brown
UNO Student Research and Creative Activity Fair
Some upland shorebird species are undergoing population declines. During their northward migration, these species primarily stop and use agricultural landscapes. This behavior is concerning because these landscapes are typically lower in resources, which could compromise energy demands during migration. There is a lack of information on what landscape features influence where species stop and on how the species use agricultural habitats. To close the gap, I compared landscape features between site where species-present and where were species-absent sites and developed models to predict migratory stopping sites. I focused on three uplands species: American Golden-Plovers, Buff-breasted Sandpipers, and Upland Sandpipers. Each …
