  Citation × Citation Citation Abstract Copy Title: Late Quaternary and Holocene Paleoecology of Interior Mesic Forests of Northern Idaho Author: Herring, Erin Year: 2014 The mesic forests distributed within the Rocky Mountains of northern Idaho are unique because many species contained within the forest are separated from their main distribution along the Pacific Northwest coast. It remains unclear whether most species within the inland disjunction survived the glacial periods of the Pleistocene, or whether they were more recently dispersed from coastal populations. To see if the dominant tree taxa of the mesic forests today could have persisted in a refugium south of the large ice sheets, four sediment cores were used to reconstruct the vegetation and climate history of the region. A nearly continuous record of pollen and sediment composition (biogenic silica and inorganic and organic matter) over the last ca. 120,000 years provides evidence of a dynamic ecosystem. Over a long timescale, the slow shifts in vegetation are attributed to the changes in climate. During the last interglacial period, the region was warmer and drier with a Pinus dominated mixed conifer forest. Approximately 71,000 years ago, a Pseudotsuga/Larix forest became established in the area as a response to the increased available moisture. As climate cooled and glaciers expanded the Pinus and Picea forest was the dominant vegetation type until ca. 40,000 years ago. The environment during the Last Glacial Maximum (LGM) was so harsh that no vegetation record was recorded. After the LGM, climate warmed, enabling a Pinus and Picea forest to establish and persist until the Holocene. The mesic taxa that dominate the modern forests did not arrive in northern Idaho until the mid- to late-Holocene. The recent arrival of the dominant tree species, Thuja plicata and Tsuga mertensiana, suggests that they likely did not persist in a refugium during the last glaciation. Instead, these species recently dispersed from coastal populations, but expansion into their interior distributions was likely limited by both climate and species competition in already established forests. During the late-Quaternary, the deposition of thick tephra layers (>20 cm) from the eruptions of Glacier Peak (ca. 13,400 years ago) and Mt. Mazama (ca. 7,600 years ago) also facilitated an abrupt and persistent change in vegetation in northern Idaho.

  Citation × Citation Citation Abstract Copy Title: The "Mourning Child": Divine and Mortal Absence in George Herbert's English and Classical Verse Author: Morton-Starner, Erica Year: 2016 The period of tumultuous religious reformation during which George Herbert lived demanded of people a strict adherence to the paradigmatic structures that prescribed the ways in which public displays of religious conviction were to be manifested. The freedom, indeed the necessity, to doubt is taken for granted by the modern reader, but for Herbert it was a matter of spiritual life and death. As country parson, he diligently labored to guide his parishioners, administer the sacraments, and exemplify the “right path.” This persona—reinforced by necessarily performative, faith-demonstrating actions—is continually destabilized by the experience of doubt, which leads Herbert to address his own persistent despair at the absence of God through poetry. His masterful use of the structural and thematic patterns of the Psalms in many of the poems of The Temple draws on the rich tradition of lament in contrast to the prescriptive, ideological agendas of the Book of Common Prayer and the Common Lectionary which privilege faith. The poems demonstrate an extensive knowledge of the epistemological foundations and history of both official Church doctrine and of medieval mystical thought and become a tool for exploring the paradoxes of human existence. His philosophical and rhetorical engagement with the Christological and ecclesiastical theology specific to Dionysian mysticism demonstrates the intensity of Herbert’s preoccupation with Divine absence and his near obsessive search for the ideal apophatic presence, that silent, knowing-unknowing that defines oneness with God. Nowhere are Herbert’s existential dilemmas more evident than in Memoriae Matris Sacrum, a sequence of poems written immediately following the death of his beloved mother, which reveals an inner life of the poet that his more controlled poetic voice of The Temple often conceals. These elegiac poems, written in Latin and Greek, show the poet as a “mourning child” and lay bare his most intimate fears about the constancy of his own faith and the uncertain terms of Christian death and resurrection embodied in the sacred ritual of the Eucharist. The poetic closure often ascribed to Herbert’s poems in fact disguises the nature of spiritual and psychological dilemmas which remain for Herbert persistent and unresolved.

  Citation × Citation Citation Abstract Copy Title: Investigation of Ambient Reactive Nitrogen Emissions Sources and Deposition in the Columbia River Gorge National Scenic Area Author: Mainord, Jacinda L. Year: 2017 Anthropogenic reactive nitrogen is emitted into the atmosphere from fossil fuel combustion (nitrogen oxides) and agricultural activities (nitrogen oxides and ammonia). Nitrogen oxide emissions have long been controlled for their role in ambient air pollution and human health effects. However, reactive nitrogen deposition is less understood even though it can play a significant role in altering biodiversity, impairing ecosystem and biogeochemical function and degrading cultural artifacts. Although nitrogen deposition is a natural part of biogeochemical cycling, many ecosystems across the United States are at risk of exceeding the critical nitrogen deposition load. While nitrogen oxides are routinely measured in urban areas, far less is known in non-urban landscapes where ecosystems may be especially sensitive. Regional chemical transport models have been used to predict the impacts of ambient reactive nitrogen deposition in non-urban areas, but models have difficulty simulating reactive nitrogen due to poorly quantified emissions, especially from the agricultural sector. My research explores the speciated deposition of reactive nitrogen through monitoring and modeling in the unique field setting of the 150 mile Columbia River Gorge (CRG) located along the border of Oregon and Washington. This site is ideally suited for this investigation due to the large sources of reactive nitrogen at either end of the CRG and unique seasonally driven channel wind flow. Seasonally driven wind allowed us to look at the reactive nitrogen emissions flowing through the CRG to assess ambient the reactive nitrogen partitioning and deposition gradient. Using data collected by the United States Forest Service to control ambient haze in the CRG and our co-located nitrogen oxides (NOx) gas analyzer, we first characterized the influence of seasonal, bimodal wind distributions on the spatial distribution of reactive nitrogen. We found that during winter months with predominantly easterly winds, particulate nitrate and ammonium and gas-phase nitrogen dioxide levels create a gradient from the eastern end to the western end. Particulate nitrate and sulfate mass concentrations influence the CRG gradient during summer months with predominantly western winds. We also found that the magnitude of the impact from east is greater than the magnitude of impact from the west. When we compared our observations to regional chemistry transport models, we found that models are significantly under-predicting levels of reactive nitrogen in the CRG. This bias is not isolated to a single station within the Gorge, but throughout the whole Columbia Basin. Our results indicate that there are under-represented emissions in the region leading to this bias. Partly due to the bias in reactive N gas-phase species in the CRG, regional models have been underestimating the impact of gas-phase reactive N on dry N deposition. We conducted field studies at two sites within the CRG monitoring reactive nitrogen species (nitric oxide, nitrogen dioxide, ammonia, nitric acid, particulate nitrate, particulate ammonium, and particulate sulfate) as well as ozone and meteorological parameters. These measurements allowed us to conduct the first comprehensive analysis of reactive nitrogen partitioning and deposition in the CRG. Through our measurements, we found reactive nitrogen was higher in the spring than the summer. We found concentrations ranging from 0-15 ppbv ammonia, 0-7 ppbv nitric acid, 0-2 μg/m3 ammonium nitrate and 0-1 μg/m3 ammonium sulfate at the sites. Through the measurements of all these species, we evaluated the limiting gas-phase precursor to inorganic nitrogen particle formation. In the springtime, ammonia limits the formation of particulate reactive nitrogen; while in the summer, nitric acid and oxidized sulfur limit the formation of inorganic nitrogen particles. This suggests that there may be more sources of ammonia in the spring with fertilizer application or perhaps reactive nitrogen reservoirs are renoxified through thermal dissociation during warmer summer months. Our estimated deposition from gas and particle phase reactive nitrogen ranged from 0 – 0.14 kg N/ha per day. We also found that gas-phase reactive nitrogen plays the largest role in dry N deposition in the CRG with particle-phase contributing less than 15% of total dry N deposition. These results are important for land managers to understand the total impact of reactive nitrogen to non-urban areas. This research can inform mitigation strategies for haze formation, identify the major species and sources involved in dry N deposition and assess the potential impacts to ecosystems and cultural artifacts.

Viral metagenomics offers a potential means of establishing a more comprehensive view of virus diversity and evolution, as vast amounts of new sequence data becomes available for comparative analysis.Metagenomic DNA from virus-sized particles (smaller than 0.2 microns in diameter) was isolated from approximately 20 liters of sediment obtained from Boiling Springs Lake (BSL) and sequenced. BSL is a large, acidic hot-spring (with a pH of 2.2, and temperatures ranging from 50°C to 96°C) located in Lassen Volcanic National Park, USA. BSL supports a purely microbial ecosystem comprised largely of Archaea and Bacteria, however, the lower temperature regions permit the growth of acid- and thermo-tolerant Eukarya. This distinctive feature of the BSL microbial ecosystem ensures that virus types infecting all domains of life will be present. The metagenomic sequence data was used to characterize the types of viruses present within the microbial ecosystem, to ascertain the extent of genetic diversity and novelty comprising the BSL virus assemblage, and to explore the genomic and structural modalities of virus evolution.Metagenomic surveys of natural virus assemblages, including the survey of BSL, have revealed that the diversity within the virosphere far exceeds what has currently been determined through the detailed study of viruses that are relevant to human health and agriculture. The number of as-yet-uncharacterized virus protein families present in the BSL assemblage was estimated by clustering analysis. Genomic context analysis of the predicted viral protein sequences in the BSL dataset indicates that most of the putative uncharacterized proteins are endemic or unique to BSL, and are largely harbored by known virus types. A comparative metagenomic analysis approach identified a set of conserved, yet uncharacterized BSL protein sequences that are commonly found in other similar and dissimilar environments.New sequence data from metagenomic surveys of natural virus assemblages was also used to better characterize and define known virus protein families, as some of the viruses found in the BSL environment represent distant relatives of well-characterized isolates. By comparing viral genes and protein sequences from these highly divergent species, it is possible to better understand the dynamics of adaptation and evolution in the virosphere. Additionally, as structures of virus proteins continue to be experimentally determined by X-ray crystallography and cryo-electron microscopy, a merger of structural and metagenomic sequence data allows the opportunity to observe the structural dynamics underlying virus protein evolution.Capsid (structural) proteins from two distinct Microviridae strains; a globally ubiquitous and highly sequence-diverse virus family, were identified in, and isolated from the BSL metagenomic DNA sample. These BSL capsid protein sequences, along with several other homologous sequences derived from metagenomic surveys and laboratory isolates, were mapped to the solved structure of a closely related capsid protein from the Spiroplasma phage-4 microvirus. Patterns of amino acid sequence conservation, unveiled by structure-based homology modeling analysis, revealed that the protein sequences within this family exhibit a remarkable level of plasticity, while remaining structurally and functionally congruent.Lateral gene transfer is thought to have had a significant impact on the genomic evolution and adaptation of virus families. Genomic context analysis was also utilized to identify interviral gene transfer within the BSL virus assemblage. An ostensibly rare interviral gene transfer event, having transpired between single-stranded RNA and DNA virus types, was detected in the BSL metagenome. Similar genomes were subsequently detected in other ecosystems around the globe. The discovery of this new virus genome dramatically underscores the scope and importance of genetic mobility and genomic mosaicism as major forces driving the evolution of viruses.The analyses conducted herein demonstrate the many ways in which viral metagenomic sequence data may be utilized to not only evaluate the composition of a natural virus assemblage, but to discover new viral genes, and to better understand the dynamics of both genomic and structural evolution within the virosphere.

  Citation × Citation Citation Abstract Copy Title: Study of Prestige and Resource Control Using Fish Remains from Cathlapotle, a Plankhouse Village on the Lower Columbia River Author: Rosenberg, J. Shoshana Year: 2015 Social inequality is a trademark of Northwest Coast native societies, and the relationship between social prestige and resource control, particularly resource ownership, is an important research issue on the Northwest Coast. Faunal remains are one potential but as yet underutilized path for examining this relationship. My thesis work takes on this approach through the analysis of fish remains from the Cathlapotle archaeological site (45CL1). Cathlapotle is a large Chinookan village site located on the Lower Columbia River that was extensively excavated in the 1990s. Previous work has established prestige distinctions between houses and house compartments, making it possible to examine the relationship between prestige and the spatial distribution of fish remains. In this study, I examine whether having high prestige afforded its bearers greater access to preferred fish, utilizing comparisons of fish remains at two different levels of social organization, between and within households, to determine which social mechanisms could account for potential differences in access to fish resources. Differential access to these resources within the village could have occurred through household-level ownership of harvesting sites or control over the post-harvesting distribution of food by certain individuals. Previous work in this region on the relationship between faunal remains and prestige has relied heavily on ethnohistoric sources to determine the relative value of taxa. These sources do not provide adequate data to make detailed comparisons between all of the taxa encountered at archaeological sites, so in this study I utilize optimal foraging theory as an alternative means of determining which fish taxa were preferred. Optimal foraging theory provides a universal, quantitative analytical rule for ranking fish that I was able to apply to all of the taxa encountered at Cathlapotle. Given these rankings, which are based primarily on size, I examine the degree to which relative prestige designations of two households (Houses 1 and 4) and compartments within one of those households (House 1) are reflected in the spatial distribution of fish remains. I also offer a new method for quantifying sturgeon that utilizes specimen weight to account for differential fragmentation rates while still allowing for sturgeon abundance to be compared to the abundances of other taxa that have been quantified by number of identified specimens (NISP). Based on remains recovered from 1/4" mesh screens, comparisons between compartments within House 1 indicate that the chief and possibly other elite members of House 1 likely had some control over the distribution of fish resources within their household, taking more of the preferred sturgeon and salmon, particularly more chinook salmon, for themselves. Comparisons between households provide little evidence to support household-based ownership of fishing sites. A greater abundance of chinook salmon in the higher prestige House 1 may indicate ownership of fishing platforms at major chinook fisheries such as Willamette Falls or Cascades Rapids, but other explanations for this difference between households are possible. Analyses of a limited number of bulk samples, which were included in the study in order to examine utilization of very small fishes, provided insufficient data to allow for meaningful intrasite comparisons. These data indicate that the inhabitants of Cathlapotle were exploiting a broad fish subsistence base that included large numbers of eulachon and stickleback in addition to the larger fishes. This study provides a promising approach for examining prestige on the Northwest Coast and expanding our understanding of the dynamics between social inequality and resource access and control.
