A mosaic approach can advance the understanding and conservation of native biodiversity in natural and fragmented riverscapes

Hitchman, Sean M. January 1900 (has links)
Doctor of Philosophy / Division of Biology / Martha E. Mather / Understanding the complex relationship between organismal distribution and spatial heterogeneity is central to many ecological questions. This challenge of identifying the biodiversity consequences of spatial patterns is especially critical for resource conservation at the larger riverscape scale because climate- and human-related impacts often act through intricate and spatially-connected organismal-habitat relationships. Specifically, resource managers cannot manage the adverse effects of common disturbances on aquatic ecosystems (e.g. water-withdrawal, dams, urbanization) if the influence of spatial heterogeneity is not recognized and understood. Towards this larger goal, I examined the role of spatial heterogeneity on stream fish biodiversity in the Upper Neosho River, KS in three ways. First, I used a mosaic approach (in which connected, interacting collections of juxtaposed habitat patches were examined) to build the scientific foundation for a general model that aids in the understanding and environmental management of disturbance-related, ecologically-based conservation problems. Second, I examined landscape metrics to quantify the impact of low-head dams on stream habitat and fish diversity. Third, I evaluated multiple quantitative approaches to develop a fuller understanding of how the arrangement of habitats across the riverscape influenced stream fish biodiversity. Related to these questions, the dissertation research provided four key take-home messages that advanced science-based conservation related to stream fish habitat and biodiversity. First, mapping larger-scale patterns of heterogeneity showed that quantitatively-different, physically-distinct pool, riffle, run, and glide habitats were arranged in unique combinations created diverse habitat mosaics across sites. Second, riffles, which comprised < 5% of all habitat patches, acted as keystone habitats that disproportionately increased fish biodiversity (i.e., species richness was significantly higher in mosaics with higher numbers of riffles). Third, mosaic approach metrics provided new insights into the influence of low-head dams on stream fish biodiversity that were not detected with traditional approaches to habitat sampling and statistical analysis. For example, low-head dams dampened the natural habitat diversity that is needed for the maintenance of resilient communities. Furthermore, using path analysis, I found that species richness was higher immediately below low-head dams as mediated through an increase in the proportion of riffle habitat, but this higher species richness was offset by a greater decrease in species richness in the impoundment habitat above low-head dams. Thus, the choice of scale influenced the interpretation of how dams affected habitat heterogeneity and resultant organismal patterns. Finally, landscape approaches to examining compositional and configurational heterogeneity provided new insights about stream fish habitat-biodiversity relationships. For example, riffle patch density had a positive effect on species richness, species richness was higher within shallow, slow flowing riffles, and adjacent neighbor habitats affected riffle species richness as mediated through alterations to within-habitat characteristics. In summary, quantifying the complex patterns of spatial heterogeneity in a range of ways can aid in the understanding of habitat-biodiversity patterns and help conserve stream fishes at a variety of scales.

Solid Metaphor and Sacred Space: Interpreting the Paradigmatic and Syntagmatic Relations Found at Beth Alpha Synagogue

Carter, Evan 17 March 2016 (has links)
With the destruction of the Second Temple in 70 CE, more than an iconic symbol of Jewish identity was destroyed. As the epicenter of religious life for Jews within the land of Israel, the Temple stood as both a symbol for religious hope and as the physical embodiment of Judaism. Yet, in the centuries that would follow synagogue’s like the one found at Beth Alpha would come to fill its absence. In this thesis I will demonstrate how the use of Christopher Tilley’s theory of the solid metaphor helps us to better understand both the art and architecture of the Beth Alpha synagogue and the synagogue’s connection to the then absent Temple. I argue that by conceptualizing this synagogue as a solid metaphor for the Temple, we can interpret how the paradigmatic and syntagmatic relations found in the composition of the mosaic carpets present sacred space. Through this application of Tilley’s theory, I argue that we can model this paradigm off of Ezekiel’s vision of the Temple.

Out of Site, But Not Out of Mind: The Conservation and Display of Ancient Roman Floor Mosaics in Situ and in Museums

Hoey, Erin M 01 January 2016 (has links)
This thesis explores the display of Roman floor mosaics in museums and in situ. Taking the original mosaic to museums for display and protection, and replacing them on site with replicas, is best for the preservation of the original material and its context.

Mytologická božstva a bytosti spojované s vodou zobrazené na mozaikách z římské doby / Mythological deities and beings associated with water depicted in the mosaics of ancient Rome

Odler, Ján January 2016 (has links)
This thesis focuses on the mosaic scenes of Roman era, especially on the gods and other mythological figures associated with water. The thesis is divided into 10 chapters. The first chapter is dedicated to the mythology of gods and characters and their brief iconographic characterization. Other chapters are divided by the areas that were under domination of Roman Empire. Each of these chapters has identical structure. The text deals with the mosaics and motifs of these areas in general. Then there are described subsequently collected examples of mosaics. On the basis of the description and characteristics is the last chapter sub-section dealing with similarities and comparison. The penultimate chapter focuses on a mosaic in terms of several aspects: production, technology, workshops, location, different techniques, signatures and trademarks. The conclusions that result from surveyed sample mosaics are summarized at the end of thesis. It is especially focused on the motifs and characters. Keywords Iconography, mosaics, Roman art, deities
