The genetics of parallel evolution: a case study using thermal and non-thermal ecotypes of Mimulus guttatus from Yellowstone National Park
… mechanisms of adaptation has long been a goal of evolutionary biologists. However, the predictability of genetic change across adaptive events and the patterns observed during adaptive transitions across species remain poorly understood. Numerous parallel evolutionary transitions within the model …

Tumour evolution in ovarian cancer using high-throughput genomics technologies
… could be explained by the model of tumour evolution. We performed SNP array analysis of a cell line model system of platinum resistance consisting of matched cell lines from three cases of HGSOC established before and after clinical resistance developed, the OVOl clinical study consisting …

Experimental evolution of Burkholderia cenocepacia biofilm populations
… chronic infections. Here we describe the parallel evolution of cooperative communities derived from a clone of Burkholderia cenocepacia during approximately 1500 generations of biofilm selection. This long-term evolution was enabled by a new experimental method that selects for daily …

Shanshuihua: ‘Mountain-water-painting’ for an ecological age
… or nature. The project also reports on the parallel evolution of the scroll in China, and how hanging scroll painting articulates the development of ink painting. The practical research, underpinned by historical and contemporary contextual study, employs strategies both reverential and …

Phylogenetic History, Morphological Parallelism, and Speciation in a Complex of Appalachian Salamanders (Genus: Desmognathus)
… taxa is important when identifying distinct evolutionary lineages using morphological characters. Desmognathus salamanders are an ideal group for testing hypotheses concerning the correlation between morphological similarity and genetic exchange within and among nominal species due to a …

Enabling collaborative modelling for a multi-site model-driven software development approach for electronic control units.
… a collaborative modelling process supporting parallel evolution. In addition, as such design is a largely creative process users are free to create layouts which appear to better depict their understanding of certain model elements presented in a diagram. That is, that the layout of the model …

Sexual Dimorphism and Trophic Trait Evolution in the Carolina Bay Fundulus Complex
Convergent evolution in similar environments is widely held to provide some of the strongest evidence for natural selection's role in evolution, and convergent or parallel evolution of reproductive isolation, best studied in some fish systems, has been interpreted as evidence of selection's role in …

Molecular systematics and biogeography of the Holarctic smelt family Osmeridae (Pisces)
… osmerid genera and revealed several interesting evolutionary patterns within the family: (1) Hypomesus chishimaensis and H. nipponensis individuals are not reciprocally monophyletic, suggesting that they are conspecific and H. chishimaensis is a recently evolved freshwater ecotype that invaded …

A Morphological and Phylogenetic Comparative approach to investigating Branching Architecture Evolution in Monocots A Dissertation
… for effective pollination. Over evolutionary time, changes in branching patterns have led to the evolution of highly diverse inflorescence architecture. This dissertation investigates the developmental and evolutionary origin of inflorescence branching architecture in monocots …

Modern Staging in Primary Breast Cancer-aspects of micrometastatic disease in bone marrow and molecular profiles in lymph node metastases
… explored in scientific settings, suggesting parallel evolution of tumour cells at primary and metastatic locations. The molecular profiles could be altered affecting individual patient’s treatment and prognosis. In the work presented in this thesis the main focus was on evaluating tumour …

Plastid to Nucleus Signalling and the Evolution of C4 Photosynthesis
… as the most remarkable example of convergent evolution known to biology, more recent analysis indicates that the C4 pathway is also underpinned by parallel evolution. For example, orthologous genes from separate C4 lineages have repeatedly been recruited into the C4 pathway such that they are …

An extensible and customizable framework for the management and orchestration of emerging software-based networks
… change network operators’ infrastructures. The evolution of telecommunication networks has always been influenced by the parallel evolution within the Information and Communication Technology (ICT) domain. What started with intelligent networks in the 90’s, namely the centralization of service …

Investigation of Genetic Alterations In Emt Suppressor, Dear1, Through Pan-Cancer Analysis and Ultra-Deep Targeted Sequencing In Ductal Carcinoma In Situ
… possibly supporting an independent yet parallel evolution between DCIS and IDC. Further, functional screens were performed on a subset of mutations identified and demonstrated that mutations effect DEAR1’s regulation of tissue architecture and TGFβ signaling. Altogether, this data …

Chromosome evolution in Lepidoptera
… only recently been able to reconstruct the exact evolutionary histories of chromosome rearrangements thanks to the availability of chromosome-level genomes. Consequently, the evolutionary forces and mechanisms that shape the varying rates of chromosome rearrangement across eukaryotes remain …

The Origins of Terpene Infochemicals in Insects: Identification and Evolutionary Analysis of Terpene Synthases in Diverse Lineages
… I have explored the genomic and functional evolution of TPS enzymes in representatives of major insect lineages. First, I investigated evolutionary and functional relationships of TPS enzymes with roles in pheromone biosynthesis in pentatomids (stink bugs) including the invasive and …

Exploring protein fitness landscapes with new high-throughput technologies
… tool to visualize core principles of protein evolution. Acquiring a new function, for example the laboratory evolution of an enzyme to convert an industrially relevant substrate, can be understood as a stepwise climb through a fitness landscape, reaching higher fitness (or activity) with each …

Evolution and assembly of the ribosome
… last universal common ancestor (LUCA). Further evolutionary studies lead to the hypothesis that the evolution of the ribosome begins with a prototype ribozyme that catalyzes peptidyl-transferase reaction. Structural and sequence analysis suggests that the small ribozyme capable of catalyzing …
