<p>Hydrogen peroxide is used by animals and plants to deter the growth of microbial invaders by inflicting DNA lesions, protein oxidation and lipid membrane modifications. Pathogens protect themselves with enzymes and ...
<p>The pace of life history is highly variable across mammals, and several evolutionary biologists have theorized that the tempo of a species' life history is set by external factors. These factors, such as food availability ...
<p>EVOLUTIONARY SKETCHES is a three-movement sextet composition for flute, clarinet in Bb, percussion, piano, viola, and cello. The idea of the piece is based on the study of applying scientific evolutionary theories to ...
<p>In this dissertation, I challenge the unitary-actor assumption of contemporary theoretical models of American politics and re-conceptualize party competition as an evolutionary process. I begin by discussing the ...
All life is organized hierarchically. Lower levels, such as cells and zooids, are
nested within higher levels, such as multicellular organisms and colonial animals. The
process by which a higher-level unit forms from the ...
<p>Edaphic factors--those pertaining to the substrate or soil--are thought to play an important role in the diversification of flowering plants. Although edaphic factors are widely interpreted as causal agents in plant ...
Over time, the U.S. economy has continued to reduce its energy and materials intensities while at the
same time increasing its total energy throughput. Taking the perspective of the economy as a system of
evolving ...
<p>Evolution can be studied at many levels, from phenotypic to molecular, and from a variety of disciplines. An integrative approach can help provide a more complete understanding of the complexities of evolutionary change. ...
<p>Narrative symphonic music dominated much of Mahler's compositional output during his early career. His early symphonic cantata,<italic>Das klagende Lied</italic> (1880-1901), and the <italic>Wunderhorn</italic> Symphonies ...
<p>Bryophytes, by their haploid dominant life cycle, possess several unique qualities ideal for study of mating patterns. In particular, the possibility of intragametophytic selfing in some species, and the vegetative ...
<p>In response to the alarming rate of serious mental illness among incarcerated individuals, local communities have operationalized the principles of therapeutic jurisprudence and forged collaborations between the criminal ...
<p>Gene duplication is an important evolutionary tool for fostering diversification and expanding gene families. However, while this concept is well understood and accepted in a theoretical capacity, the particular changes ...
<p>Understanding the mechanisms that underlie the formation of, and innovation in biochemical pathways is an important goal in evolutionary biology. The following work addresses the problem of biochemical pathway evolution ...
<p>Sexual reproduction in fungi is governed by a specialized genomic region called the mating-type locus (MAT). The ascomycetes, the largest phylum of fungi, primarily possess a bipolar mating system while the basidiomycetes, ...
<p>Evolutionary dynamics can be notoriously complex and difficult to analyze. In this dissertation I describe a population genetic regime where the dynamics are simple enough to allow a relatively complete and elegant ...
<p><italic>Cryptococcus gattii</italic> has been actively emerging and adapting to the climates and environment in western North America, bringing with it life-threatening disease to humans and animals. Through systematic ...
<p>Lysine specific demethylase 1 (LSD1) is a FAD-dependent amine oxidase enzyme responsible for removing methyl groups from the side chain nitrogen of lysine within histones in order to regulate gene transcription. By its ...
Citizens of rural Gates County, NC, have organized to oppose the Navy’s siting of an outlying landing field (OLF) in their community, which would potentially displace people from their homes and businesses, restrict access ...
Polybrominated diphenyl ethers (PBDEs) are flame-retardant compounds common in furniture, textiles, plastics, and electronic items. Throughout the use and disposal of products, PBDEs may enter the indoor or outdoor ...
Electric utilities throughout the United States are under increasing pressure by the government, the public and environmental groups to make the transition to clean power as urgency over the need to address climate change ...
