Migratory patterns of American shad (Alosa sapidissima) revealed by natural geochemical tags in otoliths
… absent. These data suggest ontogenetic shifts in migratory behavior. The thesis concludes with a report that water contributed 83% of Sr and 98% of Ba in the otoliths of a marine fish.

Migratory patterns of American shad (Alosa sapidissima) revealed by natural geochemical tags in otoliths
Geochemical signatures in the otoliths of diadromous fishes may allow for retrospective analyses of natal origins. In an assessment of river-specific signatures in American shad (Alosa sapidissima), an anadromous clupeid native to the Atlantic coast of North America, stable isotope and elemental …

Financial development, remittances and economic growth : empirical evidence from Egypt
… With the ever presence of globalization, the migratory patterns have fundamentally changed. The migration of people no longer means their total isolation from their home country; but rather a new dynamic environment has emerged with the increased importance of remittances on social, economic …

Identifying patterns and processes of sex-biases for an emerging fungal disease of wildlife
… among host-pathogen systems. Here, I identified patterns of sex-biased disease across several species of bat hosts impacted by white-nose syndrome and explored novel seasonal processes that gave rise to sex-biased disease, which ultimately scaled up to restructure populations. In scaling …

Multiple roles for Robo1/2 repellent receptors in guiding the facial nucleus and nerve
… bodies and the axons undergo specific migration patterns to assemble central neuron patterns and peripheral nerve projections to target muscles. Our goal in this study was to define the molecular signals by which the facial cell bodies and their axons correctly make this long journey. By …

Unveiling the Headscarf Debate; A Study of Multiculturalism
… in an increasingly diverse world. International migratory patterns bring people of different, often less familiar, cultures to other parts of the world, including the West. For some, assimilation into a dominant culture and broader national identity seems appropriate; for others who want to …

Using environmental DNA metabarcoding to monitor fish biodiversity and assess anthropogenic barrier impacts on the river Mersey, UK
… 30 species were detected, including all main UK migratory species except for shad. Temporal variation was found in the detected communities, in line with expectations of different species’ migratory patterns. No correlation was found between barriers and community composition along the river, …

Epidemiology of Sindbis fever in South Africa and development of a real-time pan-alphavirus PCR assay for the detection of Sindbis and other medically important alphaviruses
… largely underreported. Additionally, changing patterns of alphavirus infections are challenging conventional knowledge of these diseases and have created the need for improved diagnostic methods and increased vigilance and disease surveillance around the globe. To date, no real-time PCR assay …

Environmental impact of stocked Mulloway (Argyrosomus japonicus) in New South Wales estuaries
… marking techniques; to identify key habitats and migratory patterns of stocked fish; to evaluate the diet and growth of stocked fish and recruitment to commercial fisheries; and to develop a numerical model to estimate optimal stocking density from the predatory impact of stocked fish. The 10-step …

A Mathematical-Experimental Strategy to Decode the Complex Molecular Basis for Neutrophil Migratory Decision-Making
… response as well as dysfunctional migration patterns. This behavior has been seen in patients with sepsis, where a person's immune system overreacts to an infection, leading to systemic inflammation throughout the body, causing tissue damage, multiple organ failure, and in many cases, death. …

Multi-scale models of T cell activation
… controversy regarding when and how T cells alter migratory patterns in lymphoid tissues, as observed in intravital microscopy experiments. By developing a lattice-based model for T cell migration coupled with a mechanistically motivated simple scheme for T cell activation, I showed that the …

The genetic heritage of China: A genomic study of PR China based on nine representative ethnic populations
… genomic techniques in tracing the origins and migratory patterns of modem humans. East Asia is a particular hotspot of human migration, _especially Mainland China where a large number of human fossils have been unearthed and more than 20% of the wor1d's population now resides. There are 56 …

Errant Family Ties: Migratory Identities in Latina and Hispanic Caribbean Cultural Production
… Caribbean and Latina female voices have altered patterns of the traditional family unit and a modern conceptualization of the nation-state. In the literary trajectory of Latin American and Caribbean cultures, the family has functioned as the allegory of nation formation. Moreover, both nation and …

Integrating Research into Conservation: Using Satellite Telemetry and Population Monitoring to Inform the Management of Hawksbill Turtles in Brazil
… chapter breaks down their nesting, foraging, and migratory behaviors to inform conservation management. A significant contribution of this work is the identification of key migratory corridors and foraging areas, particularly for the subpopulation from Rio Grande do Norte, Brazil, highlighting the …

Pregnancy associated progenitor cells migrate, integrate and contribute to maternal hematopoietic compartments in the murine model
… and postpartum timepoints which may explain the migratory patterns of PAPCs to maternal tissues, injuries and neoplastic transformations. In addition, presence of VEGFR1+ CD34+ and VEGFR1+ CD133+ PAPCs in the maternal peripheral blood is highly indicative of hematopoietic progenitors of fetal …

A Translational Approach to Modeling Unique Aspects of Germ Cell Development During Self-Organization of the Primate Embryo
… An hPGC transcriptomic signature that indicates migratory potential via canonical and novel mechanisms is indicated, raising several potential candidates for further investigation into the under-studied migratory phase of germ cell development. We seek to generate validation assays of hPGC …

Advancements in Isotopic Geolocation Tools for Insect Migration Research
Migratory insects are vital components of global ecosystems and provide important ecosystem services, yet the migration phenomenon is understudied in insects compared to vertebrates. In this thesis, I aim to deepen our understanding of insect migration, using the monarch butterfly Danaus plexippus …

Neuron-Glial (NG) Interactions: A Microfluidic Examination of NG Emergent Responses for Repair
… system was used to evaluate <em>in vitro</em> migratory responses of MB-derived cells to external signaling from Epidermal Growth Factor (EGF) and stromal cell-derived factor 1-alpha (SDF-1). Data demonstrated that MB cells exhibit dosage-dependent chemotaxis towards increasing concentration …

North American Tree Bat (Genera: Lasiurus, Lasionycteris) Migration on the Mid-Atlantic Coast—Implications and Discussion for Current and Future Offshore Wind Development
… I found that sites either indicated maternity or migratory patterns in their seasonal occurrence pattern that were associated with local roosting resources (i.e., presence of forest). Across all sites, nightly occurrence was negatively related to wind speed and positively related to temperature …
