The Finch Effect: Evolutionary Metaphors And Illiberal Democracy In Central And Eastern Europe, Abigail Woodfield
The Finch Effect: Evolutionary Metaphors And Illiberal Democracy In Central And Eastern Europe, Abigail Woodfield
Claremont-UC Undergraduate Research Conference on the European Union
In recent years, several states in Central and Eastern Europe have seen democratic digression. Such illiberal resurgences came as a surprise to the many political scientists who assumed that the future of these states was democratic. Indeed, after the fall of the Soviet Union, the world largely regarded liberal democracy as the predominant system of government. The future seemed bright, and it was tempting to understand that future in evolutionary terms—just as humans evolved under natural selection to become the dominant species, democracy had survived a similar competition and defeated all other systems of government to become the dominant regime. …
A Mathematician Weighs In On The Evolution Debate, Kris H. Green
A Mathematician Weighs In On The Evolution Debate, Kris H. Green
Journal of Humanistic Mathematics
There are a variety of reasons underlying the lack of public acceptance for the theory of evolution in the United States. An overlooked cause is related to problems with the mathematics curriculum in the K-12 setting. In this essay, we examine this relationship and propose changes to the mathematics curriculum that could improve mathematical thinking while also providing a basis for understanding theories, like evolution, that are poorly understood.
Wood Anatomy Of Family Salvadoraceae From The Indian Subcontinent With Special Reference To The Ultrastructure Of The Vessel Wall, Vishakha Saxena, Sangeeta Gupta
Wood Anatomy Of Family Salvadoraceae From The Indian Subcontinent With Special Reference To The Ultrastructure Of The Vessel Wall, Vishakha Saxena, Sangeeta Gupta
Aliso: A Journal of Systematic and Floristic Botany
The present study describes the wood microstructure of Azima tetracantha, Salvadora oleoides, and S. persica, the members of family Salvadoraceae represented in the Indian Subcontinent. An identification key based on wood anatomical features has been developed for the separation of the species. SEM studies revealed the presence of vesturing in intervessel pits of Salvadora.
Descriptive Anatomy And Evolutionary Patterns Of Anatomical Diversification In Adenia (Passifloraceae), David J. Hearn
Descriptive Anatomy And Evolutionary Patterns Of Anatomical Diversification In Adenia (Passifloraceae), David J. Hearn
Aliso: A Journal of Systematic and Floristic Botany
To understand evolutionary patterns and processes that account for anatomical diversity in relation to ecology and life form diversity, anatomy of storage roots and stems of the genus Adenia (Passifloraceae) were analyzed using an explicit phylogenetic context. Over 65,000 measurements are reported for 47 quantitative and qualitative traits from 58 species in the genus. Vestiges of lianous ancestry were apparent throughout the group, as treelets and lianous taxa alike share relatively short, often wide, vessel elements with simple, transverse perforation plates, and alternate lateral wall pitting; fibriform vessel elements, tracheids associated with vessels, and libriform fibers as additional tracheary elements; …
Dicliny In Bouteloua (Poaceae: Chloridoideae): Implications For The Evolution Of Dioecy, Michael S. Kinney, J. Travis Columbus, Elizabeth A. Friar
Dicliny In Bouteloua (Poaceae: Chloridoideae): Implications For The Evolution Of Dioecy, Michael S. Kinney, J. Travis Columbus, Elizabeth A. Friar
Aliso: A Journal of Systematic and Floristic Botany
The New World grass genus Bouteloua (Chloridoideae: Cynodonteae) comprises 57 species, 13 of which produce unisexual spikelets and hence are diclinous. Andromonoecy, gynodioecy, monoecy, trimonoecy, and dioecy all occur in the genus, and ten species are known to express more than one of these breeding systems. Employing a phylogenetic estimate based on parsimony analysis of DNA sequences from the ITS (nrDNA) and trnL–F (cpDNA) regions representing 35 species of Bouteloua, including ten of 13 diclinous species, we used parsimony character state reconstructions to investigate the evolution of unisexual spikelets and breeding systems. Our specific goals were to estimate …
