T1 - Phytoplankton response to reoligotrophication in large and deep Lake Constance : Photosynthetic activity and chlorophyll concentration N2 - In Lake Constance, phytoplankton productivity, together with parameters relevant for the production process, was assessed year-round at about 500 dates between 1980 and 1995/1996. During this period, the concentration of total phosphorus during winter circulation decreased from more than 80 to 22 ;g/l as a consequence of sewage diversion and waste water treatment within the catchment area. By contrast, annual photosynthetic rates remained virtually unchanged for about 10 more years following phosphorus decline (mean value 288 " 21 g C m-2 a-1), and thereafter decreased only by about 25 % until 1996. The aim of this study is to analyze factors responsible for this pronounced resilience. Y1 - 1998 ER - TY - THES A1 - Stein, Michael C.

ED - Asinovskij, Alexander S. ED - Kasanskij, N. N. ED - Kryuchkova, E. R. ED - Falileyev, Alexandre I. T1 - How Celtic is Standard English? N2 - In this brochure, Tristram argues that Standard English may be more indebted to the influence of 'Late British' than hitherto acknowledged by mainstream historical scholarship. By 'Late British' the native (or source) language of the about 2m language shifters in the wake of the Anglo-Saxon Conquest is meant who constituted the bulk of the native population of the island of Britain in the early middle ages. Although predictably, the influence of 'Late British' on Old English neither shows in the lexis of written Old English nor in its core grammar, it does show in the phonology (Peter Schrijver) and the inflectional syncretism of the Northern dialect texts. The influence of the interlanguage of the shifters only really surfaces in Middle English texts, after the diglossia between the language of the HIGH variety of Old English of the ruling elite and the LOW variety of the working population was discontinued under Norman rule. A number of grammatical features are listed in this brochure, which show that Present Day Standard English typologically sides with the Celtic languages, and with the Neo-Brittonic languages in particular, rather than with the other Continental Germanic languages. The brochure also calls for more research into this matter and in particular detailed investigations into the individual features mentioned.

T1 - Growth of Protozoa in Antarctic lakes N2 - The growth rates of heterotrophic nanoflagellates (HNAN), mixotrophic cryptophytes, dinoflagellates and ciliates in field assemblages from Ace Lake in the Vestfold Hills (eastern Antarctica) and Lakes Fryxell and Hoare (McMurdo Dry Valleys, western Antarctica), were determined during the austral summers of 1996/1997 and 1997/1998. The response of the nanoflagellates to temperature differed between lakes in eastern and western Antarctica. In Ace Lake the available bacterial food resources had little impact on growth rate, while temperature imposed an impact, whereas in Lake Hoare increased bacterial food resources elicited an increase in growth rate. However, the incorporation of published data from across Antarctica showed that temperature had the greater effect, but that growth is probably controlled by a suite of factors not solely related to bacterial food resources and temperature. Dinoflagellates had relatively high specific growth rates (0.0057-0.384 h(-1)), which were comparable to Antarctic lake ciliates and to dinoflagellates from warmer, lower latitude locations. Temperature did not appear to impose any significant impact on growth rates. Mixotrophic cryptophytes in Lake Hoare had lower specific growth rates than HNAN (0.0029-0.0059 h(-1) and 0.0056-0.0127 h(-1), respectively). They showed a marked seasonal variation in growth rate, which was probably related to photosynthetically active radiation under the ice at different depths in the water column. Ciliates' growth rates showed no relationship between food supply and mean cell volume, but did show a response to temperature. Specific growth rates ranged between 0.0033 and 0.150 h(-1) for heterotrophic ciliates, 0.0143 h(-1) for a mixotrophic Plagiocampa species and 0.0075 h(-1) for the entirely autotrophic ciliate, Mesodinium rubrum. The data indicated that the scope for growth among planktonic Protozoa living in oligotrophic, cold extreme lake ecosystems is limited. These organisms are likely to suffer prolonged physiological stress, which may account for the highly variable growth rates seen within and between Antarctic lakes. Y1 - 2000 ER - TY - JOUR A1 - Laybourn-Parry, J. A1 - Roberts, E. C. A1 - Bell, Elanor M. T1 - Mixotrophy as a survival strategy in Antarctic lakes N2 - Mixotrophy is a widespread phenomenon among planktonic protists. It involves the combination of autotrophy and heterotrophy in varying degrees. Many phytoflagellate species ingest bacteria as a means of obtaining nutrients for photosynthesis or for supplementing their carbon budget under light limitation. Ciliates either sequester the plastids of their algal prey or harbour endosymbiotic algae. In the saline lakes of the Vestfold Hills and in Lakes Hoare and Fryxell in the McMurdo Dry Valleys the dominant phytoflagellates ingest bacteria, and there is evidence to suggest that during the winter months they lack chlorophyll and may become entirely heterotrophic. In Lake Fryxell phagotrophic pyhtoflagellates (cryptophytes) made a significant impact on bacterial production, removing up to 13% of the bacterial biomass day-1. These cryptophytes suffered predation from Plagiocampa (a ciliate), which appears to harbour them for a significant period before digesting them. We suspect that this may be equivalent to an intermediate stage in the evolution of mixotrophy. A significant number of the planktonic ciliates in Antarctic lakes were mixotrophic. The final evolutionary end point is the situation seen in Mesodinium rubrum, which now relies entirely on its cryptophycean endosymbiont and no longer ingests food. Mesodinium is the dominant ciliate in many of the saline lakes of the Vestfold Hills, which are of marine origin. It can reach abundances in excess of 60,000l-1 in Ace Lake, This ciliate is a ubiquitous member of the marine plankton worldwide and has successfully adapted to the lacustrine environment in Antarctica. The evidence suggests that among the survival strategies seen in Antarctic lake plankton, mixotrophy plays and important role among a number of the dominant protozoan species.

T1 - Untersuchungen an Hochdruckrelikten im zentralen Menderes Massiv, W Türkei N2 - Das Menderes Massiv im Westen der Türkei stellt eine große Kulmination metamorpher Gesteine dar. Das Untersuchungsgebiet ist im Zentralen Menderes Massiv (Ödemis Submassiv) gelegen, das von den beiden aktiven Gräben, dem Gediz Graben im Norden und dem Büyük Menderes Graben im Süden begrenzt wird. Die Untersuchungen der Eklogit Relikte im zentralen Menderes Massiv haben ergeben, dass sich im Menderes Massiv Hochdruckrelikte in unterschiedlichen tektonischen Positionen befinden. Zum einen existieren Eklogit-Blöcke in der obersten Einheit (Selcuk Einheit) des zentralen Menderes Massivs und zum anderen Hochdruck-Relikte in der strukturell mittleren Birgi - Tire Decke. Die Granate der quarzfreien Eklogit-Blöcke weisen große Ähnlichkeiten mit denen der HP/LT Gesteine von Sifnos und Syros auf. Die Entwicklung der Eklogit-Blöcke in der Olistostrom-Einheit lässt sich jedoch nicht mit den Eklogit Relikten in der strukturell mittleren Birgi Tire Decke vergleichen. Für die Eklogit-Relikte in der Birgi Tire Decke wurde eine polymetamorphe Entwicklung mithilfe petrologischer Untersuchungen und chemischen und Pb-Pb Datierungen herausgearbeitet. Die Eklogit Relikte gehören zu einem metamorphen Teilpfad, der durch eine Amphibolitfazies 1 - Hochdruck - Amphibolitfazies 2/Granulitfazies charakterisiert ist. Der Endpunkt dieses Teilpfades ist mit Temperaturen zwischen 700 und 750 °C und Drücken von 1.2 - 1.4 GPa belegt. Für diese Bedingungen konnte ein minimales Alter von 520 Ma durch chemische Datierungen an Monaziten einer Augengneisprobe und Pb-Pb Datierungen an Zirkonen einer Augengneis- und Metagabbroprobe bestimmt werden. Dieser amphibolit/granulitfazieller Endpunkt wird mit den Granitintrusionen des zentralen und südlichen Menderes Massiv korreliert, die in einem Zeitraum zwischen 520 Ma bis 550 Ma stattfanden. Sowohl die Amphibolitfazies 1 als auch das Hochdruckereignis werden der Panafrikanischen Orogenese zugeordnet. Für die Hochdruckbedingungen wurden maximale Temperaturen zwischen 680°C und 720°C und bei einem Druck von 2.2 GPa bestimmt. In den untersuchten Metasedimenten konnte eine prograde metamorphe Entwicklung abgeleitet werden, die amphibolitfazielle Bedingungen von 660°C bei 0.6 GPa erreichte. Das Metamorphosealter dieser Metasedimente konnte mit < 100 Ma mittels chemischer Mikrosondendatierung bestimmt werden. Die in den Metasedimenten herausgearbeiteten Druck- und Temperaturbedingungen wurden ebenfalls in den metabasischen Gesteinen bestimmt. Diese Ergebnisse werden als Krustenstapelung der metabasischen Gesteine, Augengneise und Metasedimente interpretiert, die mit der alpinen Orogenese im Zusammenhang stehen. Durch die Ergebnisse dieser Arbeit lässt sich die Birgi-Tire Decke im zentralen Menderes Massiv genauer charakterisieren. Sie besteht aus Metasedimenten, pelitischen Gneisen, Augengneisen und metabasichen Gesteinen. Die Gneise (pelitische und Augengneise) und die metabasischen Gesteine stellen panafrikanische Relikte dar, die einen amphibolit- eklogit- amphibolit/granulitfaziellen Metamorphosepfad gespeichert haben. Die amphibolit- bis granulitfazielle Metamorphose hängt mit den Granitintrusionen zusammen und fand in einem Zeitraum zwischen 520 - 550 Ma statt. Große Teile der Metasedimente der Birgi Tire Decke haben jedoch nur eine alpine metamorphe Entwicklung durchlaufen, wo sie unter amphibolitfazielle Bedingungen Krustentiefen erreichten, bei denen sie mit den panafrikanischen Relikten zusammen gestapelt wurden und eine gemeinsame Exhumierung erfahren haben. N2 - The Menderes Massif in western Turkey is a large culmination of metamorphic rocks. The investigation area is bounded by two active graben systems, the Gediz Graben in the north and the Büyük Menderes Graben in the south. One result of our investigation in the central Menderes Massif is the occurrence of eclogite relicts in different tectonic positions. On one hand eclogite blocks exist in the structurally highest nappe (Selcuk unit) of the central Menderes Massif, and on the other hand the high pressure relicts exist in the structurally middle Birgi-Tire nappe. The garnets of the quartz-free eclogite blocks in a metaolistostrome unit show large similarities with those which indicate the HP/LT rocks of Sifnos and Syros. The occurrence of the eclogite blocks in the metaolistostrome unit can not be correlated with those of the structural middle nappe (Birgi Tire nappe). By petrological investigations, chemical and Pb-Pb age determinations a polymetamorphic history was found for the eclogite relicts in the Birgi Tire nappe. The eclogite relicts belong to a metamorphic P-T path which is characterized by a amphibolite facies 1 - high pressure - amphibolite facies 2/granulite facies. The last one is characterized by temperatures between 700 and 750 °C and by pressure of 1.2 - 1.4 GPa. A minimum age of 520 Ma was deduced by chemical age determination on monazites and Pb-Pb dating on zircons. The age of the amphibolite/granulite facies condition is correlated with the granite intrusions in the central and southern Menderes Massif which occurred in the range of 520 to 550 Ma. The intrusions belong to the Panafrican orogeny. Therefore the P-T path (amphibolite facies 1 - high pressure - amphibolite facies 2/granulite facies) is assigned to the Panafrican orogeny. The maximum temperatures of the high pressure event are between 680 °C and 720 °C. The pressure amounts to 2.2 GPa. A prograde metamorphic evolution under amphibolite facies conditions was derived for the investigated metasediments. The amphibolite facies conditions took place at a temperature of 660°C and at a pressure of 0.6 GPa. The age of the metasediments was determined as < 100 Ma by means of chemical dating. The same metamorphic conditions could be recognized in the metabasic rocks. The interpretation of this result is that crustal stacking occurred under amphibolite facies conditions during the Alpine orogeny. Due to the presented results, the Birgi Tire nappe in the central Menderes Massif can be characterized more exactly. It consists of metasediments, pelitic and augengneisses, and metabasic rocks. Pelitic and augengneisses and the metabasic rocks represent Panafrican relicts, which have stored an amphibolite - eclogite - amphibolite/granulite facies P-T path. The amphibolite to granulite facies metamorphosis is related to the granite intrusions and took place in a period between 520 - 550 Ma. Parts of the metasediments belonging to the Birgi Tire nappe are influenced by only an alpine metamorphic history. They moved to crustal depths at which they were stacked with the Panafrican relicts under amphibolite facies conditions followed by common exhumation.

N2 - First, we review the current status of the detection of strong `external' variability in the CLASS gravitational B1600+434, focusing on the 1998 VLA 8.5-GHz and 1998/9 WSRT multi-frequency observations. We show that this data can best be explained in terms of radio-microlensing. We then proceed to show some preliminary results from our new multi-frequency VLA monitoring program, in particular the detection of a strong feature (~30%) in the light curve of the lensed image which passes predominantly through the dark-matter halo of the lens galaxy. We tentatively interpret this event, which lasted for several weeks, as a radio-microlensing caustic crossing, i.e. the superluminal motion of a micro-arcsec-scale jet-component in the lensed source over a single caustic in the magnification pattern, that has been created by massive compact objects along the line-of-sight to the lensed image.
