The Artemisia ludoviciana polyploid complex is a highly polymorphic
assembledge of eight taxa in the Pacific Northwest, with a
chromosome base number of x=9. A cytogenetic analysis of this
complex was carried out to determine the sources of its variation,
the types of polyploidy present, and the genetic processes active...
An adequate stand at the optimum time is an important factor
affecting potential yield and soil erosion control. However, obtaining
adequate stands of fall planted winter wheat in the dryland areas of the
Pacific Northwest is often complicated by marginal seed zone soil
moisture. The purpose of this laboratory study...
Studies of consumer-resource interactions suggest that individual diet specialisation is empirically widespread and theoretically important to the organisation and dynamics of populations and communities. We used weighted networks to analyze the resource use by sea otters, testing three alternative models for how individual diet specialisation may arise. As expected, individual...
BACKGROUND: The oxidative stress theory of life-history tradeoffs states that oxidative stress caused by damaging
free radicals directly underpins tradeoffs between reproduction and longevity by altering the allocation of energetic
resources between these tasks. We test this theory by characterizing the effects of exogenous oxidative insult and
its interaction with...

In We have analyzed natural variation in mitochondrial form and function among a set of Caenorhabditis briggsae isolates known to harbor mitochondrial DNA structural variation in the form of a heteroplasmic nad5 gene deletion (nad5 Delta) that correlates negatively with organismal fitness. We performed in vivo quantification of 24 mitochondrial...

We explored the relationship between relaxed selection, oxidative stress, and spontaneous mutation in a set of mutation-accumulation (MA) lines of the nematode Caenorhabditis elegans and in their common ancestor. We measured steady-state levels of free radicals and oxidatively damaged guanosine nucleosides in the somatic tissues of five MA lines for...
Selfish DNA poses a significant challenge to genome stability and organismal fitness in diverse eukaryotic lineages. Although selfish mitochondrial DNA (mtDNA) has known associations with cytoplasmic male sterility in numerous gynodioecious plant species and is manifested as petite mutants in experimental yeast lab populations, examples of selfish mtDNA in animals...

Tabletop role-playing games (TRPG) such as Dungeons & Dragons™ are widely known and enjoyed by diverse individuals across the world. However, TRPGs and their players historically have experienced significant stigmatization due to the misconception by some that fantasy role play leads to psychological dysfunction. While a large body of research...
Anthropogenic climate change is an escalating environmental and humanitarian emergency, but American public opinion varies on the issue, particularly in terms of whether climate change is natural or human caused. Belief that climate change is human caused has been shown to be critical in terms of support for policy action....
The accessions used to create the Snap Bean Diversity Panel were 150 snap bean (Phaseolus vulgaris) cultivars and breeding lines selected from North American and European germplasm to create a population that is representative of the snap bean market class from a historical and geographical viewpoint.

Approximately 600,000 individuals will be eventually released from the prison system and millions will be released from jails across the United States each year (Mukamal et al., 2015). Some of these individuals will make their way to a local community college to make a better life for themselves. There is...
The development of several sub-fields of general economics, including those of bounded rationality, institutional economics and the evolutionary economics, has expanded the scope and intensity of the dialogue both within economics, as well as between economists and other scientists. One of the more important preoccupations of early evolutionary economics was...
