Armenia

Early Pleistocene Environmental Changes in Southern Caucasus - Reconstruction of Climate and Vegetation Development in Armenia and Georgia at the Time of Early Human Expansion into Eurasia (Bruch, Gabrielyan and Kvavadze) 


The Environment of Early Man in Armenia - Climate and Vegetation Reconstruction of the Early Pleistocene (Gabrielyan and Bruch)

This project aims to reconstruct the Early Pleistocene environment in Armenia in order to understand the prerequisites for the first appearance of Humans in this area. This will help to localise possible archaeological sites in the future and to reconstruct the habitat of Early Man. Moreover, the results will also be put into a global perspective.
All over the territory of Armenia Pleistocene lake sediments (diatomites) occur that give evidence of a fast changing setting of lake environments since at least 2 million years. These habitats are known now by archaeologists to be favoured in Armenia by early humans at least since Middle Pleistocene. Additionally, these sequences are perfectly suitable for palaeoenvironmental studies as they are yielding various fossil remains, which can give valuable information about the flora and fauna of the period, and about climate, vegetation and lake history.
The main goals of the project are to reconstruct in detail the early Pleistocene vegetation and climate history in Armenia based on various fossil plant remains (leaves, fruits and seeds, pollen, phytoliths). Moreover, other fossil groups (diatoms, molluscs, fishes, insects) will help to identify the entire environment in and around the lake(s) in order to draw a complete picture of how suitable the landscape was for human occupation at that time.
Quantitative climate data derived from fossil floras will serve for the understanding of the regional climate development in high-resolution, and also for a correlation of the Armenian climate and vegetation history with the global record. Studies on the vegetation development, the history of landscape openness and its dependence on climate parameters will shed light on the development of grasslands in Armenia during late Neogene, which seems to be an important factor in human evolution and dispersal. However, the expected results will be not only of regional importance but also will serve for a better understanding of the global climate system in general and the interaction between climate and vegetation.

Brazil

Establishment of migration routes in the Miocene - Pleistocene, though the study of potentical fossils of the Brasin Acre - Southwest Amazon Basin and correlation with South America (Adami-Rodrigues, Haag, Negri, Scomazzon, Cardoso and Koester)

Several expeditions have been carried out in 2007 to 2008, in Amazonian sites from Acre state, Brazil, to study the paleofauna, paleoflora and palynomorphs forms. Materials were collected in strata assigned to the Late Cretaceous and Tertiary, forming part of the inheritance given to the Solimões Formation. Given the breadth and wealth of the fossiliferous deposits recorded, and the lack of data from integration works in South America is important the interpretation of the establishment of migration routes and evolutionary processes and the paleoflora paleofauna, mainly for the Amazon region of South West and fossiliferous as the records from the northwest and south of South America. The samples are located in the collections of the Paleontological Federal University of Acre, UFAC, forest and central campus. The establishment of the Cenozoic fauna of the Western Amazonia presents migratory routes related to local vegetation due north and south of South America, being the subject of discussion among researchers who work with Mio-Pliocene fauna of the Amazon. The vegetation in this case helps in the reconstruction of paleoenvironments
in order to strengthen the correlations between the Cenozoic fauna of the Amazon (Solimões Formation) and the related South American, as the fossil of rodent Proberomys bordasi, from Rio Purus, Acre, which was related material of Entre Rios, Argentina, serving as the first sign of correlation with units of eastern Peru and southwestern Brazil, as shown by the following model of the continental Tertiary of South America, this second Latrubesse & Rancy (1998). The goals involve identification and studies on the paleoflora, their diversity and age, linking it to taphoflora described for the north of Brazil, Peru, Bolivia, Chile, Venezuela and Argentina, seeking to establish the factors like paleoclimatic, paleoenvironmental and/or tectonic influence distribution in the region, understanding the development of adaptive and biogeographic patterns during the Miocene/ Pleistocene, which marked the development of the migratory routes and paleofauna and paleoflora. Only the studies together will allow significant advances in understanding the role of paleoflora
on the paleofauna in the context of Cenozoic South America.

Biocronoestratigrafy and palaeoecology based on fossil potential Cretaceous -
Neogene basin Acre, Valley Juruá, South Western Amazon (Adami-Rodrigues, Haag, Cardoso, Scomazzon and Koester)

The fossiliferous richness recorded for the Juruá Valley, Acre, composes important paleontological collections, representing mainly the paleofauna and paleoflora from Cenozoic of South America and since the most of Latin American taxa are known to the same period, is established the need for correlation studies between South American Basins. For this reason, taxonomic studies have been conducted on paleovertebrates, microinvertebrates and fossil plants in deposits of the northern region of Acre. This way, the interpretation of taphonomic processes that ensure its
preservation, the characterization of the flora, as well as evaluation of their diversity, their chronological value and its comparison with other taphoflora described for northern Brazil, Peru, Bolivia, Chile and Argentina, seeking to established between paleoclimatic, paleoenvironmental, and\or tectonic factors, which influenced their development in this area. Thus, the identification and recognition of fossil associations contribute to the establishment of adaptative and biogeographic patterns during the Cretaceous\ Miocene and Pleistocene. The project also aims to contribute to
establishment of a doctorate course in the region as a strategy for developing scientific and technological research in natural science, at the regional level, focusing on conservation of natural resources. Additionally, the consolidation of this line of research represents an opportunity for national security research in the Amazon, since the area has extraordinary biological diversity, evolved from the diverse preterit fauna and flora.

Finger prints of the Gulf Stream intensity in the Cenozoic - A view on continental climate and biodiversity on both sides of the Atlantic Ocean (Böhme, Hickler, Micheels, Mosbrugger, Portmann, Utescher; cooperation partners: Liu, Manchester and Spicer)

In the proposed project finger prints of the Northern Atlantic circulation on continental climate and its changing intensity during the Cenozoic is analysed comparing two transects in Western Eurasia and Northern America. Quantitative climate and plant diversity gradients derived from the palaeobotanical record are reconstructed for the Eocene, Oligocene, Miocene, and early to middle Pliocene in order to identify longitudinal anomalies between both continental areas. Palaeo-precipitation and temperatures are calculated using the Coexistence Approach combined with a calibration procedure recently developed. Biodiversity gradients are reconstructed using bioclimatic affinity groups of arboreal taxa. In order to identify causalities related to the development of the Gulf Stream intensity in the Cenozoic, we perform palaeoclimate modelling sensitivity experiments with an earth system model of intermediate complexity. The comparison of model and proxy data improves the interpretation of the patterns obtained from the fossil record. The analysis of the Gulf Stream and its impact on continental climates in past hothouse phases can provide valuable insights in future system change.

Hungary

Early Oligocene terrestrial climate of the Hungarian Palaeogene Basin and its surrounding area adopting fossil plant assemblages (Erdei, Hably, Roth-Nebelsick, Tamás and Utescher)

Well-dated and documented fossil leaf assemblages from the Hungarian Oligocene are compared to contemporaneous floras from the Tethys and Paratethys (localities from Italy, Serbia, Bulgaria, Austria) and from the “stable Europe” (e.g. localities from Germany). Using a morphometric approach we have the opportunity to refine quantitative climate reconstruction and indicate possible microclimatic or habitat variations. Using stomatal details we try to track habitat variations among sites.

Late Miocene biodiversity, palaeoclimate and palaeo-environment in the Pannonian Basin (Erdei, Hably, Mosbrugger and Utescher)

The project is focused on the reconstruction of ecosystem and plant diversity evolution and the quantitative estimation of palaeoclimate during the late Miocene of the Pannonian Basin, a time-span of stepwise, global cooling and the appearance of first glaciation events on the Northern Hemisphere. Based on the palaeobotanical record (both macro- and micro-remains) with adequate stratigraphic control it is possible for the first time to document spatial and temporal variation of palaeovegetation in the context of a changing climate, a main driver in shaping palaeo-environments. Vegetation and climate evolution will be documented in five time intervals covering the Tortonian and Messinian stages. In the frame of the project a novel PFT (plant functional type) classification system is developed).

Russia

Biodiversity of Vitaceae in Northern Eurasia during the Neogene in relation to climate changes (Gromyko, Herzog, Micheels, Muellner, Popova, Uhl and Utescher)

Fossil plant records belonging to the family Vitaceae are widely found in Northern Eurasia. It has been proposed that Vitaceae was one of the dominant floras in this region during the Neogene (Nikitin, 2006). Therefore, the identification of species of Vitaceae existing during the Neogene in Northern Eurasia is a prerequisite for the complete reconstruction of the Neogene climate. We currently apply the coexistance approach to reconstruct palaeoclimate in Western Siberia based on fossil plant records (Mosbrugger and Utescher, 1997) in the framework of a DAAD research grant (Popova et al., in prep.). Palaeoclimatic conditions in this region are poorly understood. In this proposed project, we aim to perform analyses of biodiversity of extinct species of Vitaceae and include this data in Neogene climate reconstructions. We
compare these results with existing biodiversity data of this family under modern climate conditions. For the first time, the combination of morphology, anatomy and biomolecular data together with fossil data is analysed for three genera of Vitaceae and incorporated with modelled and existing climate data.

United Kingdom

Shedding light on the “Dark Age” of the UK Miocene: palaeoenvironment and depositional history of the Brassington Formation, Derbyshire (Pound)

The Miocene is probably the least understood geological time period in the UK, which is partly due to the limited availability of outcrops. The Brassington Formation, Derbyshire, is a Miocene deposit which consists of gravels, sands and clays preserved in karstic hollows. Due to their accessibility, and the rarity of other Miocene sediments in the UK, the Brassington Formation is an important sedimentary succession for understanding the palaeogeography and palaeoenvironment of this geological epoch in the British Isles. The age and palaeoenvironment of the Brassington Formation have also been used to estimate rates of Pennine uplift, based on the amount of sediment subsidence and the assumption that the Brassington Formation was deposited close to Miocene sea level. This project will focus on the question of whether the Brassington Formation was deposited in a fluvial setting and then subsided, as proposed by Walsh et al. (1972), or if subsidence occurred before deposition was complete.
