Seed Dispersal: A Tale Of Two Species, W. John Hayden

Biology Faculty Publications

Orchids have minute, dustlike seeds. In this respect, Goodyera pubescens (Downy Rattlesnake Plantain), the 2016 VNPS Wildflower of the Year, is a typical orchid. Like all other orchids, Goodyera seeds contain little more than a few embryonic cells enclosed in a thin seed coat. There are two advantages to small seed size in orchids: minute seeds can be produced in prodigious quantities, and they can disperse over great distances by wind.

Effects Of Lake Erie Hypoxia On Fish Habitat Quality And Yellow Perch Behavior And Physiology, Leah Zoe Almeida

Open Access Theses

Hypoxia is a concern in freshwater, marine, and estuarine systems worldwide including in Lake Erie, North America. Hypoxia may develop more frequently and for a longer duration as a result of excess nutrient loading from human sources, therefore, the incidence of hypoxic areas has increased with human population increases and intensive land-use practices. The effects of hypoxia on fish and other aquatic organisms have been well-studied, but most research examines the negative aspects of hypoxia development on habitats and the effect of severe hypoxia on individuals. In this study we focused on less studied and more subtle effects of hypoxia, …

Responses Of Problematic Algae To Copper-Based Algaecide, Aaron Slevin, Clayton Rushing, James Cunningham, Joseph Watkins, Michael Deguenther

Undergraduate Research Conference

Eutrophication is the process by which a body of water acquires a high concentration of nutrients, especially phosphates and nitrates. These typically promote excessive growth of algae. As the algae die and decompose, high levels of organic matter and the decomposing organisms deplete the water of available oxygen, causing the death of other organisms, such as fish. Eutrophication is a natural, slow-aging process for a water body, but human activity greatly speeds up the process (USGS.gov). Golf Courses are often fertilized numerous times a year and can be major problem in fertilizer runoff in ponds surrounding the course. In east …

Overwintering Seeds As Reservoirs For Seedling Pathogens Of Wetland Plant Species, Ellen V. Crocker, Justin J. Lanzafane, Mary Ann Karp, Eric B. Nelson

Forestry and Natural Resources Faculty Publications

Seed germination and seedling establishment are central to the distribution and abundance of plant species in wetlands. While fungal and oomycete pathogens are known to affect seed viability and emergence, relatively little is known about which fungi and oomycetes are associated with seeds in the soil or how these species affect seeds and seedlings. We characterized the fungi and oomycetes associated with overwintering seeds in wetlands and determined their potential to influence seed germination and subsequent seedling mortality. Fungi and oomycetes did not affect seed germination, despite the isolation of high frequencies of known seed and seedling pathogens in the …

Recovery Of Forest Floor Diversity After Removal Of The Nonnative, Invasive Plant Euonymus Fortunei, Kali Z. Mattingly, Ryan W. Mcewan, Robert D. Paratley, Sarah R. Bray, James R. Lempke, Mary A. Arthur

Biology Faculty Publications

The vine Euonymus fortunei (Turcz.) Hand.-Mazz. is invading forests of the eastern United States; as a result, removal of E. fortunei has become a priority of resource managers. This study examined the effectiveness of five techniques for eliminating E. fortunei, restoring plant species richness, and enhancing recolonization by woody species. In 2003, the following five treatments were applied: burn with a propane torch, light exclusion by plastic tarp, burn and glyphosate application, cut (simulated grazing) and glyphosate application, mow and glyphosate application, plus an untreated control. Each treatment was replicated four times in a randomized block design located in …

Bottom-Up Ggm Algorithm For Constructing Multilayered Hierarchical Gene Regulatory Networks That Govern Biological Pathways Or Processes, Sapna Kupari, Wenping Deng, Chathura J. Gunasekara, Vincent Chiang, Huann-Sheng Chen, Hairong Wei, Et. Al.

Michigan Tech Publications, Part 1

Background: Multilayered hierarchical gene regulatory networks (ML-hGRNs) are very important for understanding genetics regulation of biological pathways. However, there are currently no computational algorithms available for directly building ML-hGRNs that regulate biological pathways.

Results: A bottom-up graphic Gaussian model (GGM) algorithm was developed for constructing ML-hGRN operating above a biological pathway using small- to medium-sized microarray or RNA-seq data sets. The algorithm first placed genes of a pathway at the bottom layer and began to construct an ML-hGRN by evaluating all combined triple genes: two pathway genes and one regulatory gene. The algorithm retained all triple genes where a regulatory …

Synthesis Of Knowledge Of Extreme Fire Behavior: Volume 2 For Fire Behavior Specialists, Researchers, Paul A. Werth, Brian E. Potter, Martin E. Alexander, Craig B. Clements, Miguel G. Cruz, Mark A. Finney, Jason M. Forthofer, W. Matt Jolly, Sara S. Mcallister, Russel A. Parsons, Scott L. Goodrick, Chad Hoffman, Roger D. Ottmar

Joint Fire Science Program Synthesis Reports

The National Wildfire Coordinating Group’s definition of extreme fire behavior indicates a level of fire behavior characteristics that ordinarily precludes methods of direct control action. One or more of the following is usually involved: high rate of spread, prolific crowning/spotting, presence of fire whirls, and strong convection column. Predictability is difficult as such fires often influence their environment to some degree and behave erratically, sometimes dangerously. Alternate terms include “blow up” and “fire storm.” Fire managers examining fires over the last 100 years have come to understand many of the factors necessary for extreme fire behavior development. This effort produced …

A Model Of The Effects Of Deforestation On Local Climate In The North Cascades, Monica R. H. Jasper

Geography and the Environment: Graduate Student Capstones

Changes in areal extent of land cover types may lead to alterations in the surface energy budget that contribute to anthropogenic climate forcing. This study examines the effects of deforestation in the Cascade Range on local temperature. Temperature sensors were installed in 14 forest stands, taking measurements for one year. Estimated tree age, circumference, and species were recorded to calculate stand density index. Satellite imagery was used to calculate shade fraction from spectral mixture analysis, which is a proxy for canopy structure and density. These data were used to construct seasonal cycles of temperature to model variation with stand density …
