Cormorants and the Loch Leven trout fishery
… are common, and such a perception exists at Loch Leven, a wetland of international importance for nature conservation and a famous commercial brown trout Salmo trutta fishery, where Great Cormorants Phalacrocorax carbo have been shot in large numbers. This thesis describes the foraging …

Geological and geochemical aspects of the Loch Loyal Alkaline Complex, Sutherland
… and geochemical parameters applicable to the Loch Loyal syenites and to relate these both to processes operating there and to the broader problems of alkaline rock genesis. Whole rock and trace element contents have been determined for the Loyal syenites and compared with other alkaline …

Laminated Sediments of Loch Ness, Scotland: Indicators of Holocene Environmental Change
… the profundal plain of the northern basin of Loch Ness, Scotland. Examination revealed that the sediment is composed of irregular sequences of pale and dark laminations, most sub-millimeter in thickness, some ca 5 mm thick. Enumeration of laminae, and determination of lamination thickness, was …

Reconstructing Loch Lomond Stadial Glaciers and Climate in the south-west English Lake District
… of the English Lake District occurred during the Loch Lomond Stadial (Younger Dryas) when full glacial conditions returned to the British Isles. The largest ice mass formed over the Western Scottish Highlands with smaller ice masses developing throughout the British uplands. In the Lake District, …

Stable isotopic insight into pelagic carbon cycling in Loch Lomond: a large, temperate latitude lake.
… material from their catchments. This input of allochthonous organic material, in addition to autochthonous organic material, has shown that lakes, particularly in temperate and boreal zones, can be heterotrophic systems and as such are net producers of CO2. Thus, understanding the magnitude of …

Palaeoenvironmental investigations into the human-environmental interactions of prehistoric communities around loch of Stenness, Orkney
… (HONO), by analysing sediment sequences from the Loch of Stenness. This study focuses on the Mesolithic (10000 cal BC to 4100 cal BC) and Neolithic (4100-2500 cal BC) periods. Research uses pollen, and unique to this study (for the Stenness area), non-pollen palynomorph and microscopic charcoal …

Aspects of the Flandrian vegetational history of south-west Scotland, with special reference to possible Mesolithic impact
… b. p.). Attention focused on upland sites by Loch Doon and Loch Dee. Upland areas by Clatteringshaws Loch and a site at Palnure near the coast provided a late and relatively incomplete record respectively. Two cores were collected at each of Loch Doon and Loch Dee to enable comparison of …

The glacial geomorphology of part of the Western Grampians of Scotland, with especial reference to the limits of the Loch Lomond Advance
… built up in the western Grampians during the Loch Lomond Stadial were mapped using O.S. maps to scales of 1 : 10,000 and 1 : 25,000. The main forms of mapped glacial evidence comprised moraines, thick till, fluvioglacial landforms, erratics, boulder spreads, ice-moulded bedforms, striae and …

The population structure of wild Scottish brown trout (Samo trutta L.1758) of Loch Maree, Wester Ross: spatial genetic distribution after population decline
The wild trout of Loch Maree is an understudied population that recently experienced a population decline after once having a world status for its sea trout fisheries. Tissues and specimens sampled over the last decade exist in archives and have yet to undergo population genetic analysis. This …

Trophic polymorphism in the Arctic charr (Salvelinnus alpinus (L.)) of Lochs Rannoch, Ericht and Tay, Scotland
Morphometric analysis of Loch Rannoch charr indicated that in addition to the pelagic morph previously described, the benthic morph previously described consists of two distinct morphs. Thus one form had a relatively small head, short gill rakers and consumed only benthic invertebrates, whilst the …

Late Devensian and early Flandrian vegetational history and deglacial chronology of Western Argyll
… the vegetational history of a region between Loch Etive and the Cowal Peninsula during the Lateglacial and early-postglacial periods, and to reconcile the varied reconstructions of Loch Lomond Readvance glaciers, proposed on geomorphic data, in the light of the palynological evidence. Two …

The late holocene evolution of coastal wetlands in Argyll, Western Scotland
… a ca. 70 km transect extending from the head of Loch Scridain (western Isle of Mull), across the Firth of Lorne to the head of Loch Etive, (mainland Argyll). Vertical activity distributions of the natural radionuclide 21OPb and anthropogenic isotopes (137Cs and 243Am) have been measured and are …

Quantifying biotic interactions with inshore subtidal structures: comparisons between artificial and natural reefs
… artificial and nearby natural rocky reefs in Loch Linnhe, west coast of Scotland.<br/>A comparative study was carried out to evaluate methods used in the assessment of subtidal epibiotic assemblage structure followed by a detailed study to compare epibiotic recruitment to artificial and …

Biogeochemistry of Metals in Fish Farm Sediments
… farming is a major industry in many Scottish sea lochs. Although the impact of salmon farming and pathways of several farm wastes have been studied extensively, there has been little research into the fate of metals originating from fish farms. This thesis investigates the influence of salmon …

Aspects of the conservation biology of Coregonus lavaretus in Britain
… evidence of residence within certain basins of Loch Lomond was found through significant differences in muscle stable isotope signatures. Investigation was also made into the trophic ecology of other fish in Loch Lomond. It was found that brown trout (Salmo trutta) in Loch Lomond have a …

High Resolution Near-Infrared Imaging Observations of the Galactic Centre
… sich vermutlich um ein supermassives Schwarzes Loch handelt. Schon seit Jahrzehnten wurde vermutet, dass die kompakte, nicht-thermische Radioquelle Sagittarius A* (Sgr A*), welche 1974 entdeckt wurde, mit einem solchen Objekt assoziiert ist. In großen Teilen basiert diese Arbeit auf …

Experimentelle Untersuchung zur biomechanischen Stabilität eines neuen Osteosynthesesystems an Kieferwinkelfrakturen

Bioavailability of dissolved organic matter in coastal waters
… quantified in two contrasting marine systems: Loch Creran (Scotland) and the Ría de Vigo (Spain). The bioavailable DOM (BDOM) varied temporally at both stations and controlled the seasonal variations in DOM. Dissolved organic phosphorus (DOP) was found to be more bioavailable than dissolved …

Investigations of microcystins (cyanobacterial peptide toxins) detection, purification and analysis.
… occurrence of several microcystins present in loch water during a single day. This study observed considerable spatial and temporal variation in the occurrence of these microcystins but suggests how sampling techniques may help reduce this variability. Ecological studies, such as that above, …
