Plaster Creek Floodplain And Adjacent Ravines Near Stanaback Park: Botanical Inventory Highlights And Management Considerations, David Warners, Garrett Crow, Haley Weesies Jan 2021

Plaster Creek Floodplain And Adjacent Ravines Near Stanaback Park: Botanical Inventory Highlights And Management Considerations, David Warners, Garrett Crow, Haley Weesies

Faculty and Professional Research

In the summer of 2021, the research team visited this area of ravines and floodplain a total of twenty-one times to conduct our field research. During the visits, they carefully walked throughout different sections of the study site, identifying each vascular plant species they saw growing there and observing how the flora developed throughout the season. In addition to keeping detailed field notes, they documented permanent records of the findings of our inventory by collecting voucher specimens that have been deposited in the Calvin University Herbarium. Additionally, they sent duplicate specimens to the Michigan State University Herbarium and/or University of …

Botanical Inventory Highlights And Management Considerations For Covenant Park, David Warners, Garrett Crow, Haley Weesies Jan 2021

Botanical Inventory Highlights And Management Considerations For Covenant Park, David Warners, Garrett Crow, Haley Weesies

Faculty and Professional Research

In the spring and summer of 2021, Calvin University students and faculty conducted a botanical inventory and assessment of the natural areas in Covenant Park, located at 3724 Shaffer Avenue SE, Kentwood, MI 49512. Given that the property was recently acquired by the City of Kentwood Parks & Recreation, the purpose of this inventory is to inform Kentwood Parks and Recreation staff about the site’s floristic quality, diversity, and ecological significance. The specific objectives of this study are to 1) provide a comprehensive inventory of the species of plants occurring on the property, 2) identify particular areas that would benefit …

Detection And Potential Virulence Of Viable But Non-Culturable (Vbnc) Listeria Monocytogenes: A Review, Nathan E. Wideman, James D. Oliver, Philip Glen Crandall, Nathan A. Jarvis Jan 2021

Detection And Potential Virulence Of Viable But Non-Culturable (Vbnc) Listeria Monocytogenes: A Review, Nathan E. Wideman, James D. Oliver, Philip Glen Crandall, Nathan A. Jarvis

Food Science Faculty Publications and Presentations

The detection, enumeration, and virulence potential of viable but non-culturable (VBNC) pathogens continues to be a topic of discussion. While there is a lack of definitive evidence that VBNC Listeria monocytogenes (Lm) pose a public health risk, recent studies suggest that Lm in its VBNC state remains virulent. VBNC bacteria cannot be enumerated by traditional plating methods, so the results from routine Lm testing may not demonstrate a sample’s true hazard to public health. We suggest that supplementing routine Lm testing methods with methods designed to enumerate VBNC cells may more accurately represent the true level of risk. This review …

Utilization Of Paenibacillus Polymyxa In The Recovery Of Lithium Bearing Minerals, Diana Bullen Jan 2021

Utilization Of Paenibacillus Polymyxa In The Recovery Of Lithium Bearing Minerals, Diana Bullen

Dissertations, Master's Theses and Master's Reports

In the global transition to green energy in the transportation and power production sectors, lithium has emerged as a viable solution, and crucial component, for the effective storage of renewable resources. To avoid further degradation of the land due to mining for virgin material, methods focused on recovering lithium must be developed. This research project seeks to explore a new way to recover lithium by using the bacterium Paenibacillus polymyxa. The bacteria were grown and then applied to the lithium bearing mineral spodumene. Settling velocity profiles were constructed for different treatments of spodumene. It was found that the spodumene …
