Keystone Microtrack: Mapping Microbes and Pathogens in the Susquehanna River Basin

This project sought to characterize Salmonella in the Susquehanna River Basin, with a focus on both prevalence and which serovars were present. Additionally, we wanted to examine basic physical characteristics, as well as the bacterial communities, of those streams. Lastly, we collated this information and developed an open-source, interactive mapping tool (Keystone MicroTrack) to make […]

Evaluating the Effects of the Recently Discovered Non-Native, Parasitic Copepods Salmincola Edwardsii and S. Californiensis on Brook Trout and Rainbow Trout, Respectively in Pennsylvania Inland Streams and Lake Erie Tributaries

The primary focus of this project is to determine the distribution, prevalence, and genetic composition of non-native Salmincola spp. (commonly referred to as gill lice) and the potential impacts that Salmincola spp. are having on the Commonwealth’s wild trout populations. Of particular concern are the impacts of Salmincola spp. on Pennsylvania’s wild Brook Trout and […]

Diet Composition of Invasive Flathead Catfish in the Susquehanna River Basin: Quantifying Impacts on Native and Migratory Fishes and Recreational Fisheries

Flathead Catfish Pylodictis olivaris are an indiscriminate predator of other fish and an expanding invader to large river systems outside of its native range, including the Susquehanna River Basin in Pennsylvania. Research efforts are beginning to provide insight on the distribution of this invader in the Susquehanna River Basin, however, there is considerable uncertainty about […]
