Lethal And Sublethal Effects Of Novel Terrestrial Subsidies From An Invasive Shrub (Lonicera Maackii) On Stream Macroinvertebrates, Ryan W. Mcewan, Kevin W. Custer, Eric B. Borth, Sean D. Mahoney

Biology Faculty Publications

The biology of headwater streams is intimately linked to that of the surrounding terrestrial environment through organic matter subsidies. Lonicera maackii, an invasive shrub that is becoming abundant in headwater stream riparian areas, deposits substantial quantities of organic matter into the aquatic system. This organic material has allelopathic effects on terrestrial plants and insects, and a growing body of work suggests strong connections between L. maackii invasion and aquatic biota. Lonicera maackii deposits fruit and flowers in quantities and timings that are unique, and we tested the hypothesis that these subsidies would negatively affect survival and growth of laboratory-cultured …

Tropical Cyclones Disrupt The Relationship Between Tree Height And Species Diversity: Comment, Teng-Chiu Lin, Lixin Wang, Chengyang Zheng, Ryan W. Mcewan, Chung-Te Chang, Jyh-Min Chiang, Chung-Hao Chi

Biology Faculty Publications

In a recent report on the patterns of tree species richness in eastern and western North America, Marks et al. (2016) claimed to have identified an operational indicator of environmental harshness (maximum tree height) and concluded that environmental stressors that limit tree height also act as ecological filters on species richness. Marks et al. (2017) attributed the positive association between species richness and maximum tree height to both the direct effects of environmental harshness on species richness and the indirect effects of environmental harshness on species richness as mediated by maximum tree height.

This finding overlooked the fact that many …

Living Seeds Of History: The John Stokes And Mary's Gardens Exhibit, Stephanie Shreffler, Kayla Harris

Marian Library Faculty Presentations

This panel describes how the University of Dayton planned and carried out an exhibit on the John Stokes and Mary’s Gardens archival collection, featuring a garden inside the library. A “Mary garden” is a garden filled with flowers named for Mary.

The panel describes the content of the collection and how the exhibit was originally conceived; the exhibit design and programming; and the challenges faced during the planning process.

The exhibit provided a way for the Libraries to promote an archival collection that not only closely connected with the University’s mission as a Catholic institution, but also provided new opportunities …

Does Riparian Forest Invasion By The Exotic Shrub Amur Honeysuckle Influence Nutrient Dynamics In Headwater Streams?, Charlotte Anne Shade

Honors Theses

Lonicera maackii (Amur honeysuckle) invasion is extensive in forests across much of Ohio and the Midwest. Amur honeysuckle has been shown to influence headwater streams and its organisms, which depend on a certain water chemistry to survive. Little has been done to understand how honeysuckle affects water chemistry and nutrient cycling. As honeysuckle canopies prevent native organic matter from entering the streams below, while also adding its own organic matter that is high in nitrogen and phosphorus, and low in lignin, the amount and types of nutrients present in both forests and streams may be significantly altered. Over a one-year …
