Evolution of deuterostome immune systems

Tassia, Michael (2021-09-10)

Contemporary theory on the evolution of metazoan immune systems is primarily derived of work on a few historically established model species (including Drosophila, human, and mouse). Though these species have provided ...

The evolution of female polymorphism in a Neotropical radiation of lizards

Paemelaere, Evi (2010-08-04)

Color pattern polymorphism – the occurrence of multiple color patterns within populations – has provided excellent opportunities for the study of evolution. Recently, a renewed interest in polymorphism was sparked by the ...

Evolution of Flowering Time in Native North American Grapevines

Jiang, Ke (2010-05-03)

Native North American grapevines represent a significant portion of the biodiversity within the genus Vitis (Vitaceae). Previous studies of taxonomy and natural history suggested patterns of biogeography, phenology and ...

The Evolution of Live Birth and the Insulin and Insulin-like Signaling Network in Sceloporus Lizards

Westfall, Aundrea (2018-07-18)

Transitions to live birth have occurred in approximately 150 different vertebrate lineages, with 115 of these alone within the clade encompassing snakes and lizards. Many questions remain about how this transition occurs ...

The Evolution of Medical Informatics as a Coherent Academic Discipline

Weigel, Fred (2011-10-26)

The purpose of this content analysis was to ascertain the prevalent themes, the challenges that exist, and future directions for the medical informatics (MI) discipline. Seven scholarly publications from the ten-year ...

Evolution of Microstructure and Its Effect on Mechanical Properties of Additively Manufactured Ni-based Superalloy During Heat Treatment

Keya, Tahmina (2023-07-28) ETD File Embargoed

Additive Manufacturing (AM) is a powerful tool to manufacture parts with unique benefits over traditional manufacturing, such as design freedom, reduction in manufacturing time and time, enabling use of broad range of ...

The evolution of milk composition and lactation strategy of the Columbian ground squirrel, Urocitellus columbianus

Skibiel, Amy (2012-06-19)

The evolution of parental care improved the efficiency of the reproductive process, allowing for the production of fewer offspring with a higher probability of survival. This adaptation is exemplified in the taxon named ...

Evolution of Miniaturization and Paedomorphism in Fishes of the Order Cypriniformes

Tan, Milton (2016-08-05)

The order Cypriniformes (carps, minnows and their allies) is a morphologically diverse freshwater fish clade numbering over 4000 species. One species is the model organism zebrafish, Danio rerio. Cypriniform fishes have ...

Evolution of Pathogen-Induced Gene Expression in the House Finch, Carpodacus mexicanus

Balenger, Susan (2011-07-25)

Bacterial pathogens impact the survival, reproduction and fitness of their hosts making them extremely well-suited for experimental studies intended to understand adaptive phenotypic evolution of wild populations of ...

The Evolution of Scatterhoarding Behavior and Behavioral Adaptations of Eastern Gray Squirrels (Sciurus carolinensis)

Ramirez, Sarah (2023-07-16) ETD File Embargoed

We investigated the evolution of scatterhoarding behavior (storing food for future use) and behavioral adaptations of eastern gray squirrels (Sciurus carolinensis). First, we simulated the evolution of scatterhoarding ...

The evolution of sexual size dimorphism in squirrels

Rajamani-Robin, Nandini (2011-08-16)

Difference between the sizes of the sexes in a species (sexual size dimorphism SSD) is a common phenomenon, and most mammals are male-biased in size. Female-biased size dimorphism (FBSD) is uncommon in mammals. Flying ...

Evolution of Signal Divergence and Behavior in Cyprinella galactura, the whitetail shiner

Phillips, Catherine (2006-12-15)

Acoustic signaling in anurans, insects, birds, and mammals has played an important role as an interspecific isolating mechanism and is also believed to be a mechanism of sexual selection in intraspecific mate choice. A ...

Evolution of target-based resistance mechanism to acetyl-coenzyme A carboxylase herbicides in Digitaria ciliaris

Basak, Suma (2021-07-16)

Digitaria ciliaris (Retz.) Koeler (southern crabgrass) is an annual grass weed of the southern United States, commonly infests all crops, non-crops, and even in turf. This grass is historically controlled in both crop and ...

The Evolution of the C# Language: The Impact of Syntactic Sugar and Language Integrated Query on Performance

Mageed, Ahmad (2010-04-09)

The C# language has seen a healthy adoption rate for a fairly young language. Each released version has introduced features that have addressed pain points in the version preceding it, as well as providing greater flexibility ...

Evolution of the Earth's Ring Current during Geomagnetic Storms

Grimes, Eric (2012-08-29)

We examine the evolution of the ring current during the main and early recovery phases of five geomagnetic storms, three driven by co-rotating interaction regions (CIRs) in the solar wind and two driven by interplanetary ...

Evolution of the Mechanical and Microstructure Properties of SAC Alloys During Thermal Cycling

Belhadi, Mohamed El Amine (2023-04-18) ETD File Embargoed

In real-time applications, solder joints are exposed to thermal and mechanical stresses. As a result, the microstructure evolves, and mechanical characteristics deteriorate, resulting in component failure. Solders have ...
