Congratulations Rooney Lab grad Jenny Gleason on having your latest manuscript from your MSc. thesis accepted for publication in the Journal Freshwater Biology.
Titled "Pond permanence is a key determinant of aquatic-macroinvertebrate community structure in wetlands," this paper uses multivariate analyses to identify hydroperiod as the main driver of macroinvertebrate community structure in prairie pothole wetlands, invoking a trait-based classification scheme that focuses on strategies for surviving desiccation.
In a new paper published in the journal Landscape Ecology, collaborators Ian Evans, Derek Robinson, and Rebecca Rooney examine over 1000 landscapes spanning a gradient in human disturbance to characterize how the configuration of wetland habitat is affected. The paper, available freely at this link, provides a method for landscape-level habitat assessments and paves the road for the development of landscape performance indicators and suitable targets for large-scale reclamation projects.
New research published from the Rooney Lab highlights the weak relationship between aquatic macroinvertebrate community structure and surrounding land use in prairie pothole wetlands. Macroinvertebrates are one of the most popular bioindicators used in freshwater ecosystems, but efforts to develop bioindicator tools with these taxa in wetlands has generated mixed results. Recent Grad from the Rooney Lab, Jenny Gleason, suggests that the strong environmental filter of wetland hydroperiod (i.e. permanence class) may be responsible.
A new paper by Rooney Lab PhD student, Courtney Robichaud, was just published in the Journal for Great Lakes Research! This article explores some of the more subtle effects of invasion by Phragmites australis on the wetland bird community. Through a comparison with a study done in 2001/02, her work suggests that a time lag exists between the initial invasion and the realization of some of these effects. You can access it free at this link until July 8th, 2017.
The Rooney Lab is seeking to fill an MSc. position to investigate the threat that invasive common reed (Phragmites australis) poses to an endangered species of spike-rush. Known from only two populations in Canada, bent spike-rush (Eleocharis geniculata) is losing its habitat to this hardy, invasive perennial grass. The research project will entail field work in the Long Point Wilderness Area and experiments in the University of Waterloo greenhouse facility.
