Cryptic diversity of a Glossopteris forest : the Permian Prince Charles Mountains Floras, Antarctica

Slater, Ben James January 2014 (has links)
The Toploje Member chert is a Roadian to Wordian autochthonous– parautochthonous silicified peat preserved within the Lambert Graben, East Antarctica. It preserves a remarkable sample of terrestrial life from high-latitude central Gondwana prior to the Capitanian mass extinction event from both mega- and microfossil evidence that includes cryptic components rarely seen in other fossil assemblages. The peat layer is dominated by glossopterid and cordaitalean gymnosperms and contains sparse herbaceous lycophytes, together with a broad array of dispersed organs of ferns and other gymnosperms. The peat also hosts a wide range of fungal morphotypes, Peronosporomycetes, rare arthropod remains and a diverse coprolite assemblage. The fungal and invertebrate-plant interactions associated with various organs of the Glossopteris plant reveal the cryptic presence of a ‘component community’ of invertebrate herbivores and fungal saprotrophs centred around the Glossopteris organism, and demonstrate that a multitude of ecological interactions were well developed by the Middle Permian in high-latitude forest mires. Comparisons of coal maceral data from co-occurring coal seams with quantitative analyses of the silicified peat constituents reveals that while silicified peats provide an unparalleled sample of the organisms forming these coal deposits, they do not necessarily reflect the constituents that ultimately dominate the coal maceral volume.

Landscape evolution in Western Amazonia : palynostratigraphy, palaeoenvironments and diversity of the Miocence Solimões Formation, Brazil

D'Apolito, Carlos January 2016 (has links)
During the Miocene (23.03 to 5.33 Ma), western Amazonia experienced major changes in its geography and biodiversity as a response to Andean uplift. To better understand these changes, the palynology of the Solimões Formation (NW Brazil) is presented with the objective of providing age control, and establishing palaeoenvironments and pollen richness within the framework of geological and climatic events. The ninety-five palynological samples yield 491 palynomorphs, of which 76 pollen and 25 spores are new. Correlation with a nearby calibrated biozonation resulted in ages from 18.7 to 10.7 Ma (late early to earliest-late Miocene). The pollen associations are typical of Amazonian humid forests, with abundant palms, Bombacoideae, trees and grasses, and lack diverse and abundant herbs or dry forest indicators. Spikes in algae and dinoflagellates show phases of lake development and two marine incursions – one between 18.4 and 17.8 Ma, and another between 14.1 and 13.7 Ma. Statistical analyses of the data show inundations had no effect in the vegetation composition. Estimates of diversity using different metrics clearly show a diversity increase and community change at ca. 16 Ma, independent of lithofacies. This change is driven by the Middle Miocene Climatic Optimum and not correlated with any of the marine incursions. Altogether, the results bring more detail to the environmental history of western Amazonia, establishing two inundation events and furthering the climate diversification relationship in Neotropical biomes into the Miocene period.

Analysis Of The Growth Dynamics In Turkish Commercial Shipbuilding Sector And Its Prospects

Sartas, Murat 01 December 2010 (has links) (PDF)
This thesis aims to analyze the growth dynamics of the Turkish commercial shipbuilding industry between 1992 and 2008. It tests the hypotheses whether each of the 14 variables identified in the literature are valid in explaining the growth of Turkish commercial shipbuilding industry between 1992 and 2008 and if there is a dierence in the importance of these variables through utilizing secondary data as well as the results of the semi structured interviews made with 16 experts and managers representing all stakeholders in public institutions, NGOs, academicians and shipyards. It argues that clustering in Tuzla, growth of world GDP and trade and specialization in chemical tankers and container ships, and three-pillar outsourcing were the major reasons for the growth of Turkish commercial shipbuilding industry for the period between 1992 and 2008 and change in dollar exchange rate is a minor reason.

The Holocene history of Pinus sylvestris woodland in the Mar Lodge Estate, Cairngorms, Eastern Scotland

Paterson, Danny January 2011 (has links)
This thesis investigates the past extent, structure and dynamics of Mar Lodge Caledonian pine (Pinus sylvestris L.) woodland, near Braemar in the south-eastern Cairngorms. The geographical extent and Holocene history of the Scottish pinewoods are generally understood, but the Mar pinewoods are relatively obscure. This thesis is concerned with the Holocene history of the Mar pinewoods; the timing and reasons for first appearance, the increase in abundance of Pinus to become a dominant species, the spatial extent of the woodland and its structure and form. The investigation includes changes to the woodland assemblage during its fragmentation and disappearance in the late Holocene and possible influences on the woodland from people living in the area. At the heart of this thesis is an understanding of the factors underpinning the ecology of Pinus and the response of the species to competition with other taxa. This is related to the spatial and temporal changes in climate that contribute to the location and development of Pinus in Scotland and Mar Lodge. Areas comparable to Mar Lodge are defined as ‘core areas’ of pine woodland rather than ‘native areas’. This avoids the necessity of considering every short period of colonisation by Pinus in areas distal to large populations. The location, extent, form and behaviour of woodland according to macro sub-fossils and micro sub-fossils is used to define core woodland as those with a long presence of Pinus, often continuing to the present day. Areas with a long history but no extant population are regarded as peripheral areas. This thesis consists of extensive palaeoecological investigations of three peat sequences: from within extant pine woodland (Doire Bhraghad), from just beyond its edge (White Bridge) and from peat with sub-fossil pine stumps located 10km west of the modern range of Pinus (Geldie Lodge). A range of techniques, including loss of mass on ignition and colorimetric light transmission analysis are applied to the peat, but palynological techniques form the basis of the investigation. Stomatal counts are used in conjunction with pollen counts to explore the process of Pinus colonisation, and its increase in abundance to form woodland. Pinus percentage and influx, together with the ratio of arboreal to non-arboreal pollen and the percentage of Empetrum are used to define the density of the woodland canopy. The stability of the Doire Bhraghad assemblage confirms the area as core Pinus woodland. Pinus is present from c. 9600 cal BP and dominates woodland from c. 9150 cal BP. Woodland here is a closed, solely Pinus canopy from c. 8600 until 4000 cal BP. Arrival of Pinus at Geldie Lodge is undated but occurs before c. 7550 cal BP. Woodland is always more open; Pinus is co-dominant with Betula, showing affinity with other peripheral areas. Pinus woodland fragments at all Mar Lodge sites from c. 3900 cal BP, disappearing from Geldie Lodge by c. 2800 cal BP and White Bridge by c. 1900 cal BP. Calluna replaces Pinus as the dominant species at all three sites. The disappearance of Pinus is thought to relate to regional climatic change toward wetter conditions. At Geldie Lodge a prior Coleopteran study suggests Pinus growing on the mire surface to be small and short lived. These may not have been the only trees growing in the area but they perhaps contributed to the major fluctuations in arboreal and non-arboreal pollen. Early canopy fluctuations (c. 7550 to 6000 cal BP) at Geldie Lodge may be related to Mesolithic human activity; there is stronger evidence of human presence from c. 4000 cal BP, possibly including cereal cultivation. Evidence from Doire Bhraghad and White Bridge is indicative only of low intensity grazing activity. It is unlikely that human activity instigated the fragmentation and disappearance of woodland, but may have contributed to the process.
