Neanderthal and Modern Human Adaptations to Climate Change in Southwest Asia: Climate Reconstruction of Marine Isotope Stage 5 to 3 based on small mammal records from Shanidar Cave (Iraqi Kurdistan)
… Neanderthals were less able to cope with rapid climate change in this period than Modern Humans. Within this context the overall aim of this thesis is to investigate the potential of microfaunal remains to provide high resolution and localised records of the environment and climate experienced …

An intersection of climate, history and landscape use: 3000 years of central Italian environmental change
Both climate change and historical events affect the environmental history of a place. Dis-entangling the two is challenging and requires independent reconstructions of climate and landscape change, as well as a thorough local historical narrative. Understanding the role climate and humans have …

Application of a New Tree-Ring Based Drought Reconstruction Method at Multiple Forest Sites Across Indiana, U.S.A.
… using multiple co-occurring species (MCOS) in a climate reconstruction model compared to a single species (SS) in four old-growth forests in Indiana: Pioneer Mothers Memorial Forest (PM), Donaldson Woods (DW), Hoot Woods (HW), and Lilly Dickey Woods (LD). The objectives of this study were to [1] …

Dendrochronological Potential of Bermuda Cedar
… structures and to reconstruct weather and climate that has impacted the Bermuda Islands over the last centuries. To date there has been no successful attempt to create a chronology from this species for historical timber dating or climate reconstruction. Construction of a regional …

Late Holocene Paleoenvironmental Reconstruction in Barbados
… modern measurements. This study presents a paleoclimate reconstruction for the late Holocene on Barbados using stable and radiogenic isotope ratios in speleothem lamina as proxies. In addition, it introduces the use of novel mineralogical analyses using Raman spectroscopy and large …

A high-resolution palaeoecological study of land use change during late prehistory on Exmoor
… debates that include the influential power of climate and the impact of human land management on the vegetation patterns in certain areas in the UK and Northwest Europe. The need and importance for higher resolution vegetation reconstructions has long been recognised in the wider literature. …

Klimarekonstruktion der Regio TriRhena mit Hilfe von direkten und indirekten Daten vor der Instrumentenbeobachtung
Das Untersuchungsgebiet des Graduiertenkollegs <br>"Gegenwartsbezogene Landschaftsgenese"; ist die Regio TriRhena (südliche Oberrheinebene und deren angrenzende Mittelgebirge). Der menschliche Einfluß auf die Landschaftsentwicklung des Oberrheingebietes war größer als bisher angenommen und ist …

Reconstruction of aspects of Northern New Zealand paleoclimate over the last 200 ka using laminated Auckland maar lake sequences
… control required to optimise paleoenvironmental reconstructions. In this context Onepoto maar paleolake in the Auckland Volcanic Field is important as it contains a high-resolution record of continuous sedimentation in the lake from its formative phreatomagmatic eruption ≤190 ka until the …

A 7000 yr runoff chronology from varved sediments of Lake Mondsee (Upper Austria)
… to investigate flood frequency under changing climate boundary conditions. This thesis follows a line of different time slices, presenting an integrative approach linking instrumental and historical flood data from Lake Mondsee in order to evaluate the flood record inferred from Lake Mondsee …

Reconstructing Tropical Pacific Climate Variability from Coral Archives
… Pacific Ocean is a critical component of the climate system, and its mean state and variability are linked to effects across the globe. Our understanding of the area is limited by the scarcity of direct observations of important climatic variables prior to the mid-twentieth century, without …

East African climate variability on different time scales : the Suguta Valley in the African-Asian Monsoon Domain
… short to long-term analyses of available climate data that I am going to present in this doctoral thesis by three different studies. 15,000 years - Suguta Valley | The main study of this thesis concentrated on the understanding of humidity changes within the last African Humid Period (AHP, …

Development of biomarker-based proxy methods for reconstructing the late Quaternary sea ice history in the Barents Sea
… isoprenoid (HBI) termed IP25 to paleo-sea ice reconstruction has confirmed its utility as a qualitative seasonal sea ice proxy. Combination of IP25 and a pelagic biomarker into the Phytoplankton-IP25 index (PIP25) has facilitated more detailed, semi-quantitative descriptions of sea ice …

Late glacial to Holocene climate and vegetation changes on the Tibetan Plateau inferred from fossil pollen records in lacustrine sediments
The past climate in central Asia, and especially on the Tibetan Plateau (TP), is of great importance for an understanding of global climate processes and for predicting the future climate. As a major influence on the climate in this region, the Asian Summer Monsoon (ASM) and its evolutionary …

1961-90 HIGH RESOLUTION TEMPERATURE, PRECIPITATION, AND SOLAR RADIATION CLIMATOLOGIES FOR ITALY
This PhD thesis focuses on the construction of monthly 30-arc-second resolution temperature, precipitation, and solar radiation 1961-90 climatologies for Italy and on the superimposition of the information of the secular anomaly records to these climatologies. The minimum, mean, and maximum …
