It Turned Into A Bioblitz: Urban Data Collection For Building Scientific Literacy And Environmental Connection, Kelly O'Donnell, Lisa Brundage

Publications and Research

In 2013, Macaulay Honors College redesigned its required science curriculum to focus on scientific literacy skills rather than content. Central to this shift was inclusion of a data collection event, a BioBlitz, to provide students with the basis for their own semester-long research projects. Students are teamed with naturalists in an urban green space to find as many species as they can in 24 h and to contribute to a global biodiversity database via the app iNaturalist. We have learned two important lessons: (1) developing an interdisciplinary curriculum with a high degree of experiential learning is more successful when both …

A Reexamination Of The Freshwater Mussel Community Of The Little Miami River, Emily Davis

Undergraduate Honors Thesis Projects

Understanding the changes in biodiversity and local freshwater mussel populations is critical to mitigate the risks to these populations. Freshwater ecosystems continue to degrade rapidly. The freshwater mussel community of the Little Miami River is degraded and has been in decline for many years. The biodiversity contained within freshwater ecosystems is lost at unprecedented rates influenced by human activity. Freshwater mussels play a key role in understanding the effects of human activity on freshwater ecosystems as well as maintaining the health of freshwater habitats. However, they are also sensitive to changes and disturbances, in their ecosystems. This study involved monitoring …

Urban Biodiversity Experience And Exposure: Intervention And Inequality At The Local And Global Scale, Evan Kuras

Masters Theses

As cities expand globally, researchers must clarify how human activities and institutions shape biodiversity and conversely, how ecological processes shape human outcomes. Two features of contemporary cities motivate this thesis. First, urban residents, and especially children, are spending less time in nature and consequently, miss out on healthy and formative experiences with biodiversity. Second, residents with the least access to biodiversity tend to be those with the lowest socioeconomic status (SES). Together, these patterns convey a multi-layered environmental injustice: not only might urbanites become increasingly estranged from biodiversity, disinterested from its conservation, and disconnected from its benefits, but these outcomes …

Eight-Legged Encounters—Arachnids, Volunteers, And Art Help To Bridge The Gap Between Informal And Formal Science Learning, Eileen Hebets, Melissa Welch-Lazoritz, Pawl Tisdale, Patricia Wonch Hill

Eileen Hebets Publications

Increased integration and synergy between formal and informal learning environments is proposed to provide multiple benefits to science learners. In an effort to better bridge these two learning contexts, we developed an educational model that employs the charismatic nature of arachnids to engage the public of all ages in science learning; learning that aligns with the Next Generation Science Standards (NGSS Disciplinary Core Ideas associated with Biodiversity and Evolution). We created, implemented, and evaluated a family-focused, interactive science event—Eight-Legged Encounters (ELE)—which encompasses more than twenty modular activities. Volunteers facilitated participant involvement at each activity station and original …

Science At Engineer Cantonment, Hugh H. Genoways, Brett C. Ratcliffe, Carl R. Falk, Thomas E. Labedz, Paul R. Picha, John R. Bozell

University of Nebraska State Museum: Mammalogy Papers

Conclusions

It is our contention that Thomas Say, Titian Peale, Edwin James, and their colleagues of the Stephen Long Expedition of 1819–1820 were heavily engaged in scientific research, which took the form of the first biodiversity inventory undertaken in the United States. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory continue to inform us today about environmental, faunal, and floral changes along the Missouri River in an area that is known to be an ecotone between the deciduous forests of the …

Herbaceous Vascular Flora Of Forested Seep Wetlands In Winneshiek County, Iowa, Usa, Elizabeth A. Lynch, Anna Burke Weckwerth

Journal of the Iowa Academy of Science: JIAS

Forested seep wetlands dominated by skunk cabbage (Symplocarpus foetidus) occur frequently in the Canoe Creek watershed of the Upper Iowa River, but this type of wetland has not been described systematically in the upper Midwest. The goal of this study is to document the herbaceous plant flora of five seeps. Although individual seeps are small (200-500 m²), they provide habitat for a high number of plant species. Five seeps with total area less than 0.2 ha supported more than 120 native vascular herbaceous taxa, 20 of which have a coefficient of conservatism (C-value) of 7 or …

La Diversidad De Los Análisis De Diversidad La Diversidad De Los Analisis De Diversidad [The Diversity Of Diversity Analyses], Victor D. Carmona-Galindo, Tizziana V. Carmona

Biology Faculty Works

There is a lack of consistency with respect to the use of the terms like species richness, diversity and biodiversity, which extends to the analysis of diversity indices and the merit of using diversity indices in the evaluation (comparison and contrast) of biological communities. The purpose of this article is to provide working definitions for these terms and cite examples from the primary literature that demonstrate the utility of estimating richness, evaluating proportional abundance patterns, as well as comparing indices of diversity and similarity to study patterns of biological organization at different ecological scales. Additionally, we provide a manual in …

4 Inches Of Living Soil: Teaching Biodiversity In The Learning Gardens–A Photo-Essay, Dilafruz R. Williams

Educational Leadership and Policy Faculty Publications and Presentations

In Learning Gardens and Sustainability Education: Bringing Life to Schools and Schools to Life, Williams and Brown (2011) place living soil at the center of the discourse on sustainability education. One of the seven principles that guides their pedagogy of learning gardens is: valuing biocultural diversity. This photo-essay of elementary students in K-8 schools, explores how 4 inches of soil in the learning gardens can teach about life’s diversity. The author urges humble attentiveness to that which is below our feet seemingly hidden and unnoticed yet teeming with life.

Living Soil And Sustainability Education: Linking Pedagogy And Pedology, Dilafruz R. Williams, Jonathan D. Brown

Educational Leadership and Policy Faculty Publications and Presentations

Sustainability is now permeating educational institutions. Yet the emerging discourse on sustainability education is in many ways caught in a modern web of theoretical, ontological, and epistemological assumptions that are incongruent with sustainability. We introduce an ecologically grounded metaphoric language rooted in living soil as an alternative regenerative framework for linking sustainability pedagogy with pedology (the study of soil). Five principles that guide this relationship are presented: valuing biocultural diversity, sensitizing our senses, recognizing place, cultivating interconnection, and embracing practical experience. Nurtured within an environment of curiosity, wonder, and questioning, and set to the rhythm and scale of localized ecologies, …

How Our Health Depends On Biodiversity, Eric Chivian M.D., Aaron Bernstein M.D., M.P.H.

Ecosystem Disruption & Climate Change

The eminent Harvard biology Professor Edward O.Wilson once said about ants, “We need them to survive, but they don’t need us at all.” The same, in fact, could be said about countless other insects, bacteria, fungi, plankton, plants, and other organisms. This fundamental truth, however, is largely lost to many of us. Rather, we humans often act as if we are totally independent of Nature, as if our driving thousands of other species to extinction and disrupting the life-giving services they provide will have no effect on us whatsoever.

This summary, using concrete examples from our award-winning Oxford University Press …

Living Soil And Composting: Life’S Lessons In The Learning Gardens, Dilafruz R. Williams, Jonathan Brown

Educational Leadership and Policy Faculty Publications and Presentations

After we spread the chicken poop, we covered it with hay... the poop was the fertilizer and the hay was the stuff that kept the plants warm. After school l checked the garden. Empty. Nobody. I climbed the fence to check the radishes I had planted. I dug around the radishes. They seemed dead. I grabbed a magnifying glass and looked closely at the leaves. Aphids were chewing all the leaves, like ants or other bugs. I went home worried. Next day I went to check the garden. Something red flashed in my eye. I panicked. "Yhaaaa!" I screamed with …

Ecological Problems With Iowa's Invasive And Introduced Fishes, Neil P. Bernstein, John R. Olson

Journal of the Iowa Academy of Science: JIAS

Since the time of European settlement, at least 59 non-indigenous fish species have been introduced, reached, or moved within Iowa waters. At least 28 nonnative fish species have been introduced into, or reported from Iowa waters since settlement. Of that number, 10 are established at this time through natural reproduction. In addition, many species of native fishes have been translocated within the state, and we provide documentation for 31 of these species. Two translocated species, gizzard shad (Dorosoma cepedianum) and yellow bass (Marone mississippiensis), have had adverse impacts on Iowa's aquatic ecosystems. While many introductions are thought to be benign, …

Iowa's Declining Flora And Fauna: A Review Of Changes Since 1980 And An Outlook For The Future, Neil P. Bernstein

Journal of the Iowa Academy of Science: JIAS

The status of Iowa's biodiversity was first summarized at a 1980 Iowa Academy of Science (IAS) symposium that was published in The Proceedings of the Iowa Academy of Science (Vol. 88, No. 1) in 1981. The 1980 symposium was updated in a recent IAS symposium, and the proceedings from this symposium are published, for the most part, in volume 105 of this journal. Most of the authors noted some positive trends, but, overall, species declines and habitat destruction remained a concern.
