Correlations in morphology between the sexes in feather mites (Acari: Astigmata): precopulatory guarding and reproductive morphologies
DownloadFall 2013
Sexual dimorphism is prominent across animals. In addition to differences in size and colouration, the sexes may also differ in non-genitalic contact traits whereby the grasping morphologies of males are matched by either cooperative or resistant corresponding structures in females. Resistance...

Development and Application of Isotope Labeling Method and Data Processing Program for Liquid Chromatography Mass Spectrometry Based Metabolome Profiling
DownloadSpring 2015
The objective of this thesis focuses on establishing a software tool (IsoMS) used in the quantification and qualification of metabolites in complex biological samples, developing robust methods to extract metabolites from different plant samples, and applying a differential 13C-/12C-isotope...

Development and Evolution of Complex Reproductive Traits in the Brassicaceae and Cleomaceae
DownloadSpring 2023
Flowering plants exhibit a bewildering diversity of forms, which raises fundamental questions on how that diversity arises. A cornerstone of evolutionary developmental biology is the expansion of comparative landscapes and establishment of focal clades that enable investigation of complex and...

Development, Anatomy, and Phylogenetic Relationships of Jawless Vertebrates and Tests of Hypotheses about Early Vertebrate Evolution
DownloadSpring 2018
The origin and early evolution of vertebrates remain one of the central questions of comparative biology. This clade, which features a breathtaking diversity of complex forms, has generated profound, unresolved questions, including: How are major lineages of vertebrates related to one another?...

Different scales of spatial segregation of two species of feather mites on the wings of a passerine bird
Download2011
Mestre, A., Mesquita-Joanes, F., Proctor, H., Monros, J. S.
The \"condition-specific competition hypothesis\" proposes that coexistence of 2 species is possible when spatial or temporal variations in environmental conditions exist and each species responds differently to those conditions. The distribution of different species of feather mites on their...

Differential expression of miRNAs in Brassica napus root following infection with Plasmodiophora brassicae
Download2014
Basu, Urmila, Verma, Shiv, Rahman, Muhammad H., Deyholos, Michael K., Kav, Nat N. V.
Canola (oilseed rape, Brassica napus L.) is susceptible to infection by the biotrophic protist Plasmodiophora brassicae, the causal agent of clubroot. To understand the roles of microRNAs (miRNAs) during the post-transcriptional regulation of disease initiation and progression, we have...

McNickle, G. G., Deyholos, M. K., Cahill Jr, J. F.
Background Ecologists recognize that plants capture nitrogen in many chemical forms that include amino acids. Access to multiple nitrogen types in plant communities has been argued to enhance plant performance, access to nitrogen and alter ecological interactions in ways that may promote...

A three-dimensional compressible resistive magnetohydrodynamic simulation code, with inclusion of the fully generalized Ohm's law, has been developed to study the nonlinear evolution of field line resonances in Earth's magnetosphere. A simple Cartesian box model of an inhomogeneous plasma with...

The emission of propagating MHD waves from the boundaries of flow channels that are unstable to the Kelvin-Helmholtz Instability (KHI) in magnetized plasma is investigated. The KHI and MHD wave emission are found to be two competing processes. It is shown that the fastest growing modes of the KHI...
