Using Polymerase Chain Reaction To Detect Nifh And Vnfdgk In A Novel Acidophilic Microbial Community, Samantha L. Flowers
Undergraduate Honors Theses
Acidophiles are widely known for their ability to exploit harsh environments, typically consisting of high temperatures, dissolved metal concentrations, and acidic conditions. Consequently, different acidophilic species are employed industrially in applications such as biomining and bioleaching. However, their full potential in bioremediation, and in industrial practices, has yet to be fully explored because many of these acidophiles are difficult to culture in laboratory conditions or have yet to be properly identified. This investigation focuses on a novel community sampled from the Richmond Mine site in Iron Mountain, California, consisting of a filamentous fungus and prokaryotes. This consortium can be cultured …

The "Playing" Field: Attitudes, Activities, And The Conflation Of Play And Games, Chad R. Carlson
The "Playing" Field: Attitudes, Activities, And The Conflation Of Play And Games, Chad R. Carlson
Faculty Research and Creative Activity
Many philosophers have attempted to describe the nature of play and games. In doing so, they have come to a number of similar conclusions. Some authors speak of play and games interchangeably, while others regard them as two distinct phenomena. However, even some of those who attempted to distinguish games from play provided ambiguous or otherwise confusing descriptions. The end result has been a tendency to conflate the two entities. This conflation is so commonplace that we regularly speak of participating in all and any games as “playing games.” In this paper I address the issue of play-game conflation and …
Terrestrial Macrofungi Of Illinois Old-Growth Prairie Groves, Scott J. Meiners, Andrew Methven, Vincent P. Hustad
Terrestrial Macrofungi Of Illinois Old-Growth Prairie Groves, Scott J. Meiners, Andrew Methven, Vincent P. Hustad
Scott J. Meiners
ABSTRACT.—Macrofungi from two old-growth prairie grove remnants in the Midwestern United States (Brownfield and Trelease Woods. Champaign Co., IL ) were surveyed over two summer and fall fruiting periods. Communities of Ascomycetes, Basidiomycetes and Myxomycètes were sampled and compared using multivariate statistical analyses. Standard estimations of species richness were calculated for comparison with other studies of fungal diversity. Environmental factors (rainfall, humidity, air temperature and soil temperature at 10 cm depth) as well as leaf litter composition, and woody plant communities were surveyed to assess their impact on fungal communities. Fungal community structure was found to differ significandy both between …

Brassica napus straw (BNS) was either not treated or was treated with two strains of Trametes versicolor; 52J (wild type) or m4D (a cellobiose dehydrogenase-deficient mutant) with four treatments. Glucose was provided to encourage growth of the mutant strain. All treatments with T. versicolor decreased (P<0.05) neutral-detergent fibre and increased (P<0.05) protein and the concentration of lignin degradation products in straw. Ergosterol was highest (P<0.05) in straw treated with B-52J, suggesting it generated the most fungal biomass. Insoluble lignin was reduced (P<0.05) in straw treated with B-52J and B-m4D, but not with B-m4Dg. Mannose and xylose concentration were generally higher (P<0.05) in straw treated with fungi, whereas glucose and galactose were lower as compared with C-BNS. The four treatments above were subsequently assessed in rumen in vitro fermentations, along with BNS treated with 5 N NaOH. Concentrations of total volatile fatty acids after 24 and 48h were lower (P<0.05) in incubations that contained BNS treated with T. versicolor as compared with C-BNSor NaOH-treated BNS. Compared with C-BNS, in vitrodry matter disappearance and gas production were increased (P<0.05) by NaOH, but not by treatment with either strain of T. versicolor. Although treatment with T. versicolor did release more lignin degradation products, it did not appear to provide more degradable carbohydrate to in vitro rumen microbial populations, even when a mutant strain with compromised carbohydrate metabolism was utilized. Production of secondary compounds by the aerobic fungi may inhibit rumen microbial fermentation.

Succession, Scott J. Meiners, Steward Pickett
Scott J. Meiners
Succession in a strict sense refers to the recovery and revegetation of an area following a disturbance such as the cessation of agriculture, the retreat of a glacier, or an intense forest fi re. Succession is a special case of vegetation dynamics, although many early ecologists referred to all vegetation change as succession. Succession includes a series of compositional and structural changes, often in a directional manner. The common occurrence of natural disturbances coupled with the extent of human activity on the planet makes succession one of the most ubiquitous ecological processes. Because invasion is a crucial feature of succession, …
Quantitative Analysis Of Lignocellulosic Components Of Non-Treated And Steam Exploded Barley, Canola, Oat And Wheat Straw Using Fourier Transform Infrared Spectroscopy, P. K. Adapa, L. G. Schonenau, Thomas Canam, T. Dumonceaux
Quantitative Analysis Of Lignocellulosic Components Of Non-Treated And Steam Exploded Barley, Canola, Oat And Wheat Straw Using Fourier Transform Infrared Spectroscopy, P. K. Adapa, L. G. Schonenau, Thomas Canam, T. Dumonceaux
Thomas Canam
Rapid and cost effective quantification of lignocellulosic components (cellulose, hemicelluloses and lignin) of agricultural biomass (barley, canola, oat and wheat) is essential to determine the effect of various pre-treatments (such as steam explosion) on biomass used as feedstock for the biofuel industry. Fourier Transformed Infrared (FTIR) spectroscopy was considered as an option to achieve this objective. Regression equations having R2 values of 0.89, 0.99 and 0.98 were developed to predict the cellulose, hemicelluloses and lignin compounds of biomass, respectively. The average absolute difference in predicted and measured cellulose, hemicellulose and lignin in agricultural biomass was 7.5%, 2.5%, and 3.8%, respectively.

• Premise of the study : Recent analyses employing up to fi ve genes have provided numerous insights into angiosperm phylogeny, but many relationships have remained unresolved or poorly supported. In the hope of improving our understanding of angiosperm phylogeny, we expanded sampling of taxa and genes beyond previous analyses.• Methods : We conducted two primary analyses based on 640 species representing 330 families. The fi rst included 25 260 aligned base pairs (bp) from 17 genes (representing all three plant genomes, i.e., nucleus, plastid, and mitochondrion). The second included 19 846 aligned bp from 13 genes (representing only the …
Domain And Propositions Of Succession Theory, Steward Pickett, Scott J. Meiners, Mary L. Cadenasso
Domain And Propositions Of Succession Theory, Steward Pickett, Scott J. Meiners, Mary L. Cadenasso
Scott J. Meiners
Succession is perhaps the oldest of ecological concepts, having arisen when ecology was emerging as a self-conscious discipline (Mcintosh 1985). Yet it continues to address many fundamental issues in ecology, to support important applications, and to synthesize the insights and perspectives of other theories. Thus, it fulfills two functions key in assessing the utility of a contemporary ecological theory. First, it exhibits the attributes of a mature, welldeveloped, and intensively tested theory (Glenn-Lewin et al. 1992; Pickett and Cadenasso 2005). Second, it provides a linkage among theories and applications that have usually been considered separately (Walker et al. 2007). For …

Aceraceae - Acer Griseum, Janice Coons, Nancy Coutant, Wesley Whiteside
Plants by Family
Acer griseum was first brought to North America in 1907 by Ernest Henry Wilson in the form of two seedlings that were collected from Hubei Province in China. These two original plants remain at the Arnold Arboretum in Boston, Massachusetts, and were the source of the first North American horticultural distribution of the plant in 1927 (Del Tredici 2007). It is a handsome plant with very showy bark and is becoming more popular and easier to obtain than it has been in the past.

While never becoming a dominant tree, the bigleaf magnolia has a wide natural range in forests as far south as Georgia, west to Louisiana and Arkansas, north up to Ohio and Kentucky with it being most common in south central Mississippi. It prefers shady and moist areas along gorges (Callaway 1994).
