The question of whether a hagfish is a true vertebrate or not has profound implications about the ancestry of the clade. New anatomical evidence allows a test of their systematic position. With dissections and serial sections of original specimens, and with a literature review, a comparative...
We introduce a new methodology that allows the construction of wave frequency distributions due to growing incoherent whistler-mode waves in the magnetosphere. The technique combines the equations of geometric optics (i.e., raytracing) with the equation of transfer of radiation in an anisotropic...
Homology in comparative, molecular, and evolutionary developmental biology: The radiation of a conceptDownload
The present paper analyzes the use and understanding of the homology concept across different biological disciplines. It is argued that in its history, the homology concept underwent a sort of adaptive radiation. Once it migrated from comparative anatomy into new biological fields, the homology...
Traditional analyses of Anabaptist action continue to be problematized by substantial theological, social, economic, ethical, and political disparities defining the early decades of sixteenth-century Anabaptist movements. This dissertation is offered as a “reconciliation,” as an attempt to...
Mitochondrial cytochrome oxidase I and 11 genes were sequenced for two invasive alien birch (Betula L. [Betulaceae]) leaf-mining sawflies, Profenusa thomsoni (Konow, 1886) (Hymenoptera: Tenthredinidae) and Scolioneura betuleti (King, 1816) (Hymenoptera: Tenthredinidae), accidentally introduced...
