The Floral Charms Of Saint John’S: A Survey Of Botanical Communities, 2016 College of Saint Benedict/Saint John's University
The Floral Charms Of Saint John’S: A Survey Of Botanical Communities, Stephen G. Saupe, Paul Melchior
Headwaters: The Faculty Journal of the College of Saint Benedict and Saint John’s University
Saint John’s is a “landscape paradise” in central Minnesota. Although no complete checklist of vegetation exists for the campus, various surveys reveal a diverse flora. This floral wealth is the result of several terrestrial biomes converging on campus — prairie, savanna, deciduous forest, and coniferous forest — as well as diverse aquatic habitats including both lakes and wetlands. A 56-acre restored prairie at the entrance of Saint John’s is dominated by big bluestem and little bluestem. A savanna has been restored to the north and east of the Gemini Lakes and is characterized by bur oaks scattered among prairie grasses ...
Habitat Temperature And Precipitation Of Arabidopsis Thaliana Ecotypes Determine The Response Of Foliar Vasculature, Photosynthesis, And Transpiration To Growth Temperature, 2016 University of Colorado Boulder
Habitat Temperature And Precipitation Of Arabidopsis Thaliana Ecotypes Determine The Response Of Foliar Vasculature, Photosynthesis, And Transpiration To Growth Temperature, William W. Adams Iii, Jared J. Stewart, Christopher M. Cohu, Onno Muller, Barbara Demmig-Adams
Ecology & Evolutionary Biology Faculty Contributions
Acclimatory adjustments of foliar vascular architecture, photosynthetic capacity, and transpiration rate in Arabidopsis thaliana ecotypes (Italian, Polish [Col-0], Swedish) were characterized in the context of habitat of origin. Temperatures of the habitat of origin decreased linearly with increasing habitat latitude, but habitat precipitation was greatest in Italy, lowest in Poland, and intermediate in Sweden. Plants of the three ecotypes raised under three different growth temperature regimes (low, moderate, and high) exhibited highest photosynthetic capacities, greatest leaf thickness, highest chlorophyll a/b ratio and levels of β-carotene, and greatest levels of wall ingrowths in phloem transfer cells, and, in the Col-0 ...

Endless Symbioses Most Intricate, 2016 University of Richmond
Endless Symbioses Most Intricate, W. John Hayden
Biology Faculty Publications
Orchids, such as our Wildflower of the Year for 2016, Downy Rattlesnake Plantain (Goodyera pubescens) (Fig. 1), exemplify the interconnectedness of life on Earth. As would be the case for many kinds of plants, pollination comes readily to mind as a prominent example of mutualistic symbiosis. Downy Rattlesnake Plantain is pollinated by bumblebees and other native bees. The bees gain nectar and the orchid gets an efficient means to move pollen from one flower to another; each organism gains benefit from the interaction, the very definition of mutualism. Pollination by bees is widespread among the orchids, but there can be ...

Per Axel Rydberg’S Botanical Collecting Trips To Western Nebraska In 1890 And 1891, 2016 University of Nebraska-Lincoln
Per Axel Rydberg’S Botanical Collecting Trips To Western Nebraska In 1890 And 1891, Robert B. Kaul, David M. Sutherland
In the summer of 1891, Per Axel Rydberg and his assistant, Julius Hjalmar Flodman, collected plants in western Nebraska for the United States Department of Agriculture. They collected many first-records for Nebraska as well as some that became type specimens of Rydberg’s and other botanists’ names. In the following autumn and winter, Rydberg made a detailed, typewritten, carbon copied 35-page Report and 37-page List of specimens from that trip; one carbon copy is in the Bessey Herbarium (NEB) at the University of Nebraska–Lincoln. It is these documents that we present here, extensively annotated with our geographic clarifications, original ...
Mapping Morels: Predicting The Locations Of Morchella Species Through Environmental Factors Using The Gis System, 2016 Augustana College - Rock Island
Mapping Morels: Predicting The Locations Of Morchella Species Through Environmental Factors Using The Gis System, Emily M. Stanevicius
Celebration of Learning
Morel mushrooms, Morechella esculenta and M. deliciosa, are known delicacies across the globe, ranging from exquisite dishes in French cuisine to Eastern palates such as Japanese Matsutake. According to literature, true morels diverged as their own genus about 129 million years, again which has led to the development of more than 177 species and have been part of the human diet since their beginning. However, the elusiveness of morels has contributed to the mushrooms infamy for rarity, and has even been known to sell for more than $40 per pound. This project seeks to aid in the search for morels ...

By the fourth week, the average height of the control plants was 105.7 ...
Preserving Biodiversity For A Climate Change Future: A Resilience Assessment Of Three Bay Area Species--Adenostoma Fasciculatum (Chamise), Arctostaphylos Canescens (Hoary Manzanita), And Arctostaphylos Virgata (Marin Manzanita), 2016 University of San Francisco
Preserving Biodiversity For A Climate Change Future: A Resilience Assessment Of Three Bay Area Species--Adenostoma Fasciculatum (Chamise), Arctostaphylos Canescens (Hoary Manzanita), And Arctostaphylos Virgata (Marin Manzanita), Alison S. Pollack
Anthropogenic climate change is an undeniable threat to the future of the natural world and human civilization. These shifts will have profound impacts on vegetation, especially for species endemic to isolated regions or sensitive to climate change factors. However, species resilience can predict success into the next century. Resilience is defined as the ability to withstand climate change factors, whereas vulnerability is defined as susceptibility to climate induced stress or damage.
Chaparral and coastal scrub ecosystems within the Bay Area of California provide a unique context for examining resilience, as many species are adapted to high temperatures, drought, and wildfire ...

Management Of Remnant Prairie Ecosystems: Soil Transfer, Fire, And Exotic Species Invasion, 2016 Indiana University - Purdue University Fort Wayne
Management Of Remnant Prairie Ecosystems: Soil Transfer, Fire, And Exotic Species Invasion, Adam R. Warrix
Property management is an important aspect in sustaining the Earth’s ecosystems. Anthropogenic changes to the planet have made conservation important in maintaining species abundance and diversity as well as limit damages to sensitive ecosystems. Invasive species have become a standard, consistent problem in managed ecosystems. Such species often invade into disturbed areas, which commonly are a result of restoration or other management activities. In dredging open water bodies at Eagle Marsh Nature Preserve (Allen County, IN), artificial mounds were constructed with the soil removed. This movement of soil created a disturbance which facilitated for the recruitment and colonization of ...

Vascular Flora Of The Possum Walk Trail At The Infinity Science Center, Hancock County, Mississippi, Hanna M. Miller
The North American Coastal Plain contains some of the highest plant diversity in the temperate world. However, most of the region has remained unstudied, resulting in a lack of knowledge about the unique plant communities present there. This flora catalogues the vascular plant species along the Possum Walk Trail on the southeast corner of the Infinity Science Center in Hancock County, Mississippi. Additionally, interpretive signs have been developed to display information about engaging species and phenomena to increase public interest in native plant life and involve them conservation efforts. The site was surveyed from spring of 2015 to spring of ...
Friend Or Foe—Light Availability Determines The Relationship Between Mycorrhizal Fungi, Rhizobia And Lima Bean (Phaseolus Lunatus L.), Daniel J. Ballhorn, Martin Schädler, Jacob D. Elias, Jess A. Millar, Stefanie Kautz
Biology Faculty Publications and Presentations
Plant associations with root microbes represent some of the most important symbioses on earth. While often critically promoting plant fitness, nitrogen-fixing rhizobia and arbuscular mycorrhizal fungi (AMF) also demand significant carbohydrate allocation in exchange for key nutrients. Though plants may often compensate for carbon loss, constraints may arise under light limitation when plants cannot extensively increase photosynthesis. Under such conditions, costs for maintaining symbioses may outweigh benefits, turning mutualist microbes into parasites, resulting in reduced plant growth and reproduction. In natural systems plants commonly grow with different symbionts simultaneously which again may interact with each other. This might add complexity ...

The purpose of this study will be to investigate the claim that administration of lavender (Lavandula angustifolia) essential oil (topically, orally, and/or respiratorily) produces a relaxative effect in human subjects. This investigation will theoretically be conducted in two stages. Stage one will focus primarily on determining the presence of therapeutic effects and the relative effectiveness of lavender in several application modalities. Stage two will proceed based on findings from stage one. If significant parasympathetic effects are observed in relation to one or more of the lavender oil modalities described above, a more focused investigation will be conducted in stage ...
The Ecology Of Extrafloral Nectar In Senna Mexicana Var. Chapmanii, 2016 Florida International University
The Ecology Of Extrafloral Nectar In Senna Mexicana Var. Chapmanii, Ian M. Jones
FIU Electronic Theses and Dissertations
Extrafloral nectar (EFN) mediates food-for-protection mutualisms between plants and defensive insects. Senna mexicana var. chapmanii is a perennial legume native to the pine rockland habitats of south Florida. My dissertation focuses on how anthropogenic changes to the pine rocklands might affect EFN production by S. chapmanii, and the outcome of EFN mediated interactions. First, I investigated the influence of time of day, leaf damage, and leaf age on EFN production in S. chapmanii. Plants produced more nectar at night than during the day, and leaf damage resulted in increased EFN production. Furthermore, the response to leaf damage was greater when ...
