  Citation × Citation Citation Abstract Copy Title: The Influence of Behavior and Hydrodynamics on the Dispersal of Dungeness Crab, Cancer magister, Larvae Author: Rasmuson, Leif Year: 2016 The Dungeness crab fishery is the most economically important on the West Coast; however, it has experienced dramatic fluctuations in annual catch. Previous research has shown the annual catch of megalopae is correlated with the commercial catch. The catch of megalopae is correlated with the phase of the Pacific Decadal Oscillation (PDO), the day of the year of the spring transition and the amount of upwelling following the spring transition. Further, the daily catch of megalopae is correlated with the internal tide. We developed individual based models of Dungeness crab dispersal, which we validated with results from a light trap. We demonstrated that the retention of larvae in the California Current is enhanced during negative phase PDOs. Further, we suggest that larvae migrate to or almost to the bottom each day. Specifically, megalopae exhibit a twilight vertical migration off of the continental shelf and remain in the neuston on the continental shelf. This concentrates megalopae at the continental shelf break. We also observed megalopae in situ and demonstrated that they swim in the neuston with the surface current at speeds of ~ 10 cm s-1. Using these results and data from a mooring, we demonstrated that this behavior would increase the distance internal waves would transport larvae. We analyzed mooring data and suggest that catch of megalopae is greater when the thermocline is deep and weak and there is less horizontal shear. We hypothesize this allows internal waves to remain coherent longer on the continental shelf. We show that the spring transition coincides with a shallowing of the thermocline, which would ultimately lead to the development of internal waves of depression rather than elevation. We hypothesize that the change in surface flow, based on whether the wave is one of elevation or depression, explains why most megalopae are caught following the spring transition. In general, these findings help us better understand the dispersal of Dungeness crabs. We suggest the dispersal patterns support Michael Sinclair’s member vagrant hypothesis. Further, we suggest these findings apply to many of the continental shelf species in the California Current. This dissertation includes both published and unpublished co-authored materials.

  Citation × Citation Citation Abstract Copy Title: Paleocoastal Resource Use and Human Sedentism in Island Environments: A Case Study from California's Northern Channel Islands Author: Jew, Nicholas Year: 2013 The peopling of the Americas, including the possibility that maritime peoples followed a coastal route from Northeast Asia into the New World, is a topic of major interest in archaeology. Paleocoastal sites on California`s Northern Channel Islands (NCI), dating between ~13,000 and 8000 years ago, may support this coastal migration theory. Until recently, however, we knew little about Paleocoastal technologies, settlement, and lifeways on the islands. Combining traditional archaeological approaches with experimental and archaeometric techniques, I examine Paleocoastal settlement and resource use on San Miguel and Santa Rosa islands. Recently discovered Paleocoastal sites have produced sophisticated chipped stone technologies, with bifacially-flaked points and crescents of extraordinary craftsmanship. Exploring lithic raw material procurement strategies, I demonstrate a Paleocoastal preference for island cherts from sources centered on western Santarosae. Using experimental and archaeometric techniques, I show that Paleocoastal peoples systematically employed heat-treatment to manufacture finely crafted bifaces from island cherts. Using stable oxygen isotope (δ18O) analyses of marine shells from Paleocoastal sites, I examine paleo-sea surface temperatures, seasonality of shellfish collecting, and human sedentism. Evaluating whether such occupations were seasonal or year-round, I tested different sampling strategies for California mussel shells, showing that a method used by many California archaeologists provides erroneous seasonality interpretations for ~35 percent of sampled shells. Using a more intensive sampling strategy, I demonstrate that some Paleocoastal sites were used seasonally, but three substantial middens dating to 8200, 9000, and 10,000 cal BP produced evidence for shell harvesting during all four seasons. This suggests that the NCI were occupied more or less permanently and year-round by at least 10,000 years ago. My research suggests that Paleocoastal peoples had a strong commitment to maritime and island lifeways starting at least 12,000 years ago. From that time until ~8000 years ago, Paleocoastal peoples relied primarily on island resources despite their close proximity to the mainland. The presence of a relatively large, permanent, and distinctive Paleocoastal population on the NCI may also support the coastal migration theory and an even deeper antiquity of human settlement and sedentism on the NCI. This dissertation includes previously published and unpublished co-authored material.

  Citation × Citation Citation Abstract Copy Title: ON THE HISTORICITY OF SOCIAL AND ECOLOGICAL CHANGE: FROM THE ASIAN CARP INVASION TO THE REVERSAL OF THE CHICAGO RIVER Author: Besek, Jordan Year: 2017 The increasingly unsustainable relationship between society and the environment is drawing considerable attention across disciplines. In sociology this attention has focused largely on developing theoretical frameworks for explicating how various social processes negatively impact the environment, however what sociology has done less well is develop rich understandings of the other side of this relationship, how ecological change can create instability in social processes. To fill this gap I employ an extended case study of the interplay between the social and ecological processes related to the introduction of Asian carp, an invasive species that has set into motion considerable contestations across political, cultural, economic and scientific social processes in the greater Chicago area as well as the Great Lakes. Through this case study I demonstrate how ecological changes, such as the migration of Asian carp, can impact social processes. I then provide an historical analysis of the 1900 reversal of the Chicago River to show how social responses to the Asian carp invasion are structured through previous histories. My aim is to demonstrate that the Asian carp invasion is not, in itself, a single transformative process, but rather a cumulative development generated and constrained via several connected social and ecological histories. My overall aim is to demonstrate the benefit of examining how social histories and ecological histories combine over time, or the historicity of social and ecological interaction.

  Citation × Citation Citation Abstract Copy Title: Bound by Blackness: African Migration, Black Identity, and Linked Fate in Post-Civil Rights America Author: Abedi-Anim, MeCherri Year: 2017 This dissertation explores the identity formation of Ethiopian and Nigerian immigrants, their second generation children, and native born African Americans who reside in the Seattle metropolitan area. Using boundary formation theory, I argue that African immigrants and their second generation children are developing a shared sense of Black identity and racial solidarity (linked fate) with native born African Americans. This shared Black identity is illustrated through both Africans and African Americans’ recognition of one another as racial group members, the constraints on their Black identities, and their navigation of similar institutional and political contexts. I argue that this is highly suggestive of an expansion of the Black racial boundary, and the reconstitution of Black identity in the post-Civil Rights Era. Despite some boundary contraction within the Black racial category by some 1st generation Africans, the African 1.5 and second generation are engaging in boundary crossing particularly with African Americans through their bicultural identities. This process appears to be leading to the blurring of boundaries between the children of African immigrants and native born African Americans, especially through the 1.5 and second generations involvement and integration into African American social and professional organizations. Evidence presented in this dissertation suggests that there is a weakening of ethnic identity among the African 1.5 and second generation. This weakening of ethnic identity among the children of Ethiopians and Nigerians suggest subsequent generations of Africans born here in the United States will eventually be absorbed into an undifferentiated African American/Black category.
