Precisely dated terrestrial paleoclimate records are indispensable for understanding how different regions respond to global-scale climate variability. Here, we focus on developing precisely dated records from the Bonneville Basin, a large basin in the eastern U.S. Great Basin. This region is known to have been highly sensitive to hydroclimate changes during the past glacial period; closed-basin lakes in this region have been studied for over a century. We present lake and speleothem records from the Bonneville Basin that are anchored by high-precision U-Th ages. Deep-lake carbonates are deposits that form beneath the surface of lakes in crevices and protected spaces. We explore these deposits as an archive of past hydrological change in the Bonneville Basin. Deep-lake carbonates deposits were collected from varying elevations in the basin and microsampled for U-Th dating. The results of this work improve constraints on existing lake level information for Lake Bonneville. Additionally, we present [delta]234U data from these carbonates that records changes in weathering, and by extension, hydrology, in the Bonneville Basin. 87Sr/86Sr ratios of deep-lake carbonates reflect relative changes in fluvial input between the northern and southern sub-basins of the Bonneville Basin, allowing for the reconstruction of past precipitation patterns. This record shows that there were distinctly different patterns of atmospheric circulation over the Bonneville Basin during Heinrich Event 2 and the Last Glacial Maximum. Finally, we present records Mg/Ca ratios and [delta]13C values of speleothems from Lehman Caves, NV, located on the western edge of the Bonneville Basin. These records suggest that the onset of mid- Holocene drying in the Great Basin was at 8.2 ka, coincident with the collapse of the Laurentide Ice Sheet.

Full textClimate change is considered to be one of the most severe threats to earth and aquatic ecosystems and the concern about the effects that global warming can have on biological communities is growing. Even if the number of studies concerning climate change is worldwide increasing the effects of climate change are challenging to monitor and understand because of the multitude of responses within an ecosystem. In the last years, analyses of long-term data sets provide increasing evidence on the sensitivity of water bodies to climatic fluctuation. Small size and fast reproducing zooplankton organisms are sensitive to environmental change. Moreover, they represent key components of aquatic food webs, connecting primary producers to big secondary consumers as fishes. The purpose of the present PhD research is to expand the knowledge on the zooplankton communities of the large and deep lakes south of the Alps, detecting trends and significant change or shift in the pelagic food webs structure due to global or local impacts. The analysis of long-term series of limnological observations and a paleolimnological study on lake sediment have been combined in order to disentangle the effects of climate change from that due to more local and anthropic stressor as eutrophication. The obtained results suggested that in deep subalpine lakes the effect of climate change on pelagic food webs components is complex, including several direct and indirect effects, and it is mediated by nutrient availability. In particular, in deep lakes winter climatic variability trigger a cascading effect that involves the entire lake ecosystems, modifying lake chemical, physical and biological characteristic. The effects of warmer winter temperature can reverberate on zooplankton seasonal patterns until summer, affecting the food webs functioning. The paleolimnological investigation, through the combined study of biotic and abiotic factor, allowed clarifying the synergic effects of the most important drivers of change in lake ecosystems, suggesting that climatic factors should be considered with nutrient availability as a determinant element in controlling the temporal development of plankton communities and pelagic food web structure.

Full textEine der großen Herausforderungen der heutigen ökologischen Forschung ist es, Veränderungen von Ökosystemen vorherzusagen, die mit dem Klimawandel einhergehen. Dafür sind ein umfassendes Verständnis der verschiedenen Steuerungsfaktoren des entsprechenden Systems und Kenntnisse zur Anpassungsfähigkeit des Systems nötig. Auf der Grundlage dieses Wissens, können mit mathematischen Modellen Klimaszenarien gerechnet und Vorhersagen erstellt werden. Die vorliegende Arbeit untersuchte die Regulation des Phytoplanktons (kleine freischwebende einzellige Algen) und seiner Konsumenten (Zooplankton, tierische Kleinstlebewesen) sowie deren Wechselspiel während des Frühjahrs mit Bezug auf den Klimawandel. Als Basis dienten langjährige Daten von einem großen tiefen See (Bodensee) sowie Daten von Versuchen mit Organismen aus einem flachen marinen Gewässer (Kieler Förde, Ostsee). Diese Daten wurden mit statistischen Verfahren und mathematischen Modellen ausgewertet. In Gewässern sind Algen als Primärproduzenten die Nahrungsgrundlage für tierische Organismen bis hin zu Fischen und Meeresfrüchten, und bestimmen die Wasserqualität der Gewässer. Daher ist es wichtig zu verstehen, welche Mechanismen die Dynamik der Algen steuern. Der Grundstein für die saisonale Entwicklung von Phyto- und Zooplankton in Gewässern unserer Breiten wird mit dem Beginn des Wachstums im Frühjahr gelegt. Diese Arbeit zeigt, dass es bereits im zeitigen, noch kalten Frühjahr ein Wechselspiel physikalischer und biologischer Steuerungsmechanismen für die Algenentwicklung gibt. Physikalische Faktoren sind die Wassertemperatur, die Globalstrahlung und die Durchmischung des Gewässers, die durch die Stärke des Windes beeinflusst wird. All diese Steuerungsmechanismen sind eng miteinander verwoben und werden unterschiedlich stark vom Klimawandel beeinflusst. Mit mathematischen Modellen gelang es den Einfluss einzelner Faktoren voneinander zu trennen und zu zeigen, dass Effekte durch den Klimawandel sich gegenseitig aufheben oder aber auch verstärken können. Schon geringe Änderungen an der Basis der Nahrungsnetze können weitreichende Auswirkungen auf höhere Ebenen habe. Wie stark diese Auswirkungen im Einzelnen sind, hängt entscheidend von der Anpassungsfähigkeit gesamter Ökosysteme und ihrer Artengemeinschaften sowie einzelner Individuen ab. Beispielsweise reagiert die Algengemeinschaft auf einen starken Fraßdruck ihrer Räuber mit einer Verschiebung zu weniger gut fressbaren Algenarten. Diese weniger gut fressbaren Arten unterscheiden sich jedoch auch in anderen Eigenschaften, wie zum Beispiel der Ressourcenausnutzung, von besser fressbaren Algen. In dieser Arbeit wurden Modellansätze entwickelt, die diese Fähigkeit zur Anpassung berücksichtigen. Auf dieser Grundlage und mit Einbeziehung der physikalischen Steuerungsfaktoren können Klimaszenarien gerechnet werden und Vorhersagen für den Einfluss des Klimawandels auf unsere Gewässer gemacht werden, die letztlich auch Perspektiven für Handlungsmöglichkeiten aufzeigen.
