Streszczenie:

Pas de résumé en français<br>Southern African drylands are not suited for the application of climate reconstruction methods based on surface samples. Methods based on the co-existence approach, while still in their early days, are really promising, particularly those using probability density functions (pdfs) that have proven particularly valuable in certain cases as they can be applied to a wide range of plants assemblages. Most commonly applied to fossil pollen data, their performance can be limited by the taxonomic resolution of the pollen data, as many species may belong to a given pollen-

Streszczenie:

Huge changes in climate occurred at the end of the last Quaternary glaciation. The end of this glaciation corresponds with the end of Pleistocene with its repeated glacial cycles and the start of the current geological epoch, the Holocene interglacial. The climate at this time was characterized by increasing temperatures and an increase in rainfall. This project focuses on understanding and examining these changes in climate using loess deposits from south-western England. Loess is an aeolian sediment and covers around 10 % of the Earth’s land surface and these deposits are excellent archives

Öræfajökull is an ice-capped stratovolcano situated in the south east of Iceland which has developed throughout the mid to late Quaternary. It has erupted basaltic and rhyolitic lavas during interglacial and glacial periods, many of which display strong physical evidence of volcano-ice interaction. This makes Öræfajökull an ideal location to reconstruct terrestrial palaeo-environments. The area of Goðafjall and Hrútsfjall is one of a small number of rhyolitic depositional centres situated on the south west flanks of the volcano and is the first rhyolitic area of Öræfajökull to be mapped in det

Climate variability has had a dramatic impact on eastern Grand Canyon tributaries over the past -100 ky. This is readily observed in the Lava Chuar and Comanche catchments, which host well preserved colluvial remnants and river terraces that resulted from several climate-induced cycles of aggradation and incision. This study investigates these climate responses using surveying, sedimentology, and luminescence geochronology methods to investigate the mechanisms and timing of their deposition. The survey data demonstrate that the concavity of terrace treads is lower than modern drainages. The se

The Lake Heron basin is an intermontane basin located approximately 30 kms west of Mount Hutt. Sediments within the basin are derived from a glacier that passed through the Lake Stream Valley from the upper Rakaia Valley. The lack of major drainage in the south part of the basin has increased the preservation potential of glacial phenomena. The area provides opportunities for detailed glacial geomorphology, sedimentology and micropaleontogical work, from which a very high-resolution study on climate change spanning the Last Glacial Maximum (LGM) through to the present was able to be reconstruc

The aeolian sediment loess, which consists of mineral dust, is one of the most detailed terrestrial record of both global and regional climate changes. As climate changes in the past cover a much wider range of climate variability than humans have directly recorded, the soil memory of loess is vital for understanding the Earth’s climate system. By examining past climate records and analyzing past climate changes and factors that have instigated changes, inferences regarding future climate can be made.

Streszczenie:

Aquesta tesi doctoral es centra en la paleoecologia de l’Illa de Pasqua (Rapa Nui) (27ºS 109ºW). El present treball ha caracteritzat la vegetació a la conca del llac i la seva dinàmica com a resposta als canvis ambientals durant els darrers 34000 anys a partir d’indicadors ambientals (macrorestes vegetals, diatomees, registre palinològic, geoquímic i fàcies sedimentari) analitzats en sediments de testimonis de sondeig del llac Raraku. Els resultats han evidenciat variacions significatives en la composició de la vegetació en relació a canvis climàtics a llarg termini, modificacions de la morfol

As glaciações do Quaternário moldaram os padrões filogeográficos das espécies em geral. Em algumas regiões da América do Sul, (e.g. Cerrado e Caatinga) a mudança estrutural foi mais acentuada, havendo o predomino de savanas, ao passo que em outras regiões (e.g. Amazônica e Mata Atlântica) as mudanças foram menores, formando áreas de refúgios florestais. A Modelagem Preditiva de Distribuição de espécies usa associações entre variáveis ambientais e registros de ocorrência da espécie para estimar modelos que representam as condições ambientais favoráveis à espécie. Neste trabalho foram estudadas

Les fluctuations du climat et du niveau marin, de plus ou moins grande amplitude, influencent le taux d’érosion sur le continent, le transport de sédiment vers l’océan et sa distribution vers le bassin profond. Les canyons sous-marins, structures érosives de premier abord, sont les zones de transfert privilégiées entre le plateau continental et le bassin profond. Peu d’études se sont concentrées sur la relation entre le remplissage des canyons, l’acheminement des sédiments et les variations du niveau marin. La chronologie de leur mise en place et de leur évolution aux échelles de temps géologi
