2021-2022 Tallgrass Prairie Center Highlights, Tallgrass Prairie Center, University Of Northern Iowa

Annual Reports

From our director:

The roots of the Tallgrass Prairie Center go back to the 1980s, when UNI Biology Professor Daryl Smith began to collaborate with the Black Hawk County Secondary Roads Department. It was passion for prairie, combined with practicality, that drove this unusual partnership. Then in 1988, the Iowa Legislature wrote a powerful idea into the Iowa code: that it is in the public interest to manage Iowa’s roadsides for multiple purposes using ecological principles.

The Native Roadside Vegetation Center at UNI was formed to meet the practical challenges of that idea. Subsequently renamed the Tallgrass Prairie Center, we …

Comparison Of Plant Richness And Density In Crp-42 Fields Between 2018 And 2022, Liz Wilgenbusch, Ai Wen Ph.D. Jul 2022

Comparison Of Plant Richness And Density In Crp-42 Fields Between 2018 And 2022, Liz Wilgenbusch, Ai Wen Ph.D.

Summer Undergraduate Research Program (SURP) Symposium

Recently, the number of pollinators have decreased dramatically throughout the United States. Pollinators play an important role in food production with around ⅓ of the world’s food crops being dependent on pollinators. Providing a high-forage habitat for pollinators is a proposed solution to combat their decline. In the upper Midwest United States, the Conservation Reserve Program (CRP) helps protect pollinator habitats by providing farmers with annual payments to retire their old farmland. The purpose of this study was to compare plant density and richness in CRP fields between year 3 and year 7 post planting to find trends in the …

The Development Of A Photographic Atlas Of Plant Adaptations For Pollination, Bethany Van Dusseldorp Jan 2022

The Development Of A Photographic Atlas Of Plant Adaptations For Pollination, Bethany Van Dusseldorp

Honors Program Theses

Plants have biotic, abiotic, or both biotic and abiotic adaptations for pollination, depending on how they are structured and the attraction between the plant and pollinator. The main focus for this project was biotic adaptations for pollination, and how various plants are specifically structured for the insect, bird, or mammal to pick up the pollen and carry it to the next plant. Documentation, using image/focus stacking and macro photography, was done of the structures of various plants from the University of Northern Iowa (UNI) Botanical Center to support the reason for why plants are structured the way they are. While …


Developing Methods To Assess The Role Of Lumbricus Terrestris On Seed Predation In Prairie Restoration, Jacey R. Meier Jan 2022

Developing Methods To Assess The Role Of Lumbricus Terrestris On Seed Predation In Prairie Restoration, Jacey R. Meier

Honors Program Theses

Tallgrass prairie used to cover Iowa and much of the midwest, but now only a small percentage of it remains. Many prairie restoration efforts are in place to revitalize Iowa’s former prairie landscape. Native prairie seed that is genetically diverse and regionally appropriate is expensive, and only 5-10% of the seeds planted germinate into seedlings. Ungerminated seed loss can occur many ways, one being due to seed predation. The common earthworm, Lumbricus terrestris, is a seed predator that has been observed to be present at prairie restoration sites by its numerous middens. The goal was to develop methods that would …

Changes In The Barley Stem Proteome In Response To Drought During Grain Filling, Mohammed Al Slamh Jan 2022

Changes In The Barley Stem Proteome In Response To Drought During Grain Filling, Mohammed Al Slamh

Dissertations and Theses @ UNI

Drought is the major environmental factor that limits crop yield worldwide. Crops are particularly vulnerable to drought at the reproductive stage. In cereals, grain filling during drought depends on the contribution of current photosynthesis products from the leaf and spike and carbohydrates stored mainly in the stem and remobilized to the grain. Even though stem reserve is an important source for grain filling, changes in the proteome of barley stem under drought have not been studied. Also, the molecular events associated with differential stem reserve remobilization under drought are not well understood. In this study, barley plants were exposed to …


Understanding Morphological Responses Of Typha (Cattail) Species To Nutrient Pollution, Anna Marie Shapiro Jan 2022

Understanding Morphological Responses Of Typha (Cattail) Species To Nutrient Pollution, Anna Marie Shapiro

Dissertations and Theses @ UNI

In the Midwestern United States, Typha x glauca is a hybrid of the native Typha latifolia and the non-native Typha angustifolia. Typha x glauca is considered invasive, and it is dominating Typha latifolia when they co-occur. Wetlands in the Midwest face nutrient pollution, due to fertilization used within the agricultural industry. Wetlands are nutrient sinks, which store the increased levels of nitrogen and phosphorus. These nutrients are known to increase Typha growth. Within this thesis, it was hypothesized that an increase of nitrogen in the wetland may increase the width of Typha leaves, making it difficult to distinguish the …
