Studying The Effects Of Serpentine Soil On Adapted And Non-Adapted Species Using Arduino Technology, Kiana Saniee, Edward Himelblau, Brian Paavo

STAR Program Research Presentations

Abstract: Serpentine soils are formed from ultramafic rocks and are represent an extreme environment for plants. Serpentine soils are unique in that they carry high concentrations of heavy metals, are nutrient deficient, particularly in calcium, and have poor water retention capabilities. Although these soils constitute harsh conditions for plant growth, there are a number of species that are adapted and even endemic to serpentine soil. Water retention by commercial potting mix was compared with serpentine soil. Also, serpentine adapted and non-adapted species were grown in both soil treatments and physiological data were collected. We used the Arduino electronic platform to …

Principles Of Biology, Robert Bear, David Rintoul, Bruce Snyder, Martha Smith-Caldas, Christopher Herren, Eva Horne

Open Access Textbooks

This textbook is designed specifically for Kansas State's Biology 198 Class. The course is taught using the studio approach and based on active learning. The studio manual contains all of the learning objectives for each class period and is the record of all student activities. Hence, this textbook is more of a reference tool while the studio manual is the learning tool.

The textbook was originally published and is also available to download at http://cnx.org/contents/db89c8f8-a27c-4685-ad2a-19d11a2a7e2e@24.1.It is licensed under a Creative Commons Attribution License 4.0 license.

Plant Functionality Across An Environmental Gradient, Taylor L. Price, Julie Zinnert

Undergraduate Research Posters

Community assemblages provide insight into ecosystem processes, both spatially and temporally. They interact with biotic and abiotic factors that vary with habitat structure, influencing community composition. Ecological theory demonstrates that species have the potential for a wide fundamental niche, but habitat range may be restricted by factors exposed to species in their realized niche. In barrier island ecosystems, edaphic and environmental characteristics (e.g. elevation and distance to shoreline) are major drivers determining where and how plant communities establish. Physical stressors, such as salt stress and drought influence community grouping and can alter plant function within the environment. With projected increases …

Comparison Of Pea Seed Germination Due To Manipulation Of Soil Conditions, Ariel M. Kershner

Faculty Curated Undergraduate Works

This experiment was done with the intent to understand optimal soil conditions for pea seed germination. We investigated this using three soil conditions – 100% potting soil, 50% potting soil/50% sand, and 100% sand. Seemingly healthy pea seeds were planted and observed over five weeks. We measured both the total number of sprouts per week and the combined weight of the plants and seeds per condition before planting and after uprooting. We expected to find that the 100% potting soil condition would germinate the best, resulting in the most sprouts and heaviest weight of the condition’s seeds and plants. This …
