DIGSTER - Map and Go (Digital Satellite Based Terrain Model) - User Requirements

The project DIGSTER - Map and Go (Digital Based Terrain Mapping) aims at the technical aspects of digital terrrain mapping. For many questions in administration, planning and expertise terrrain mappings are indispensable. The whole process starting with the data acquisition in the field and ending with map products will be digitally performed by the system. Therefore, a platform appropriate for the use in the field (PDA) is combined with technologies from the disciplines of satellite navigation, remote sensing, communication, and mobile geoinformation systems. For DIGSTER a lot of practical applications already exist in connection with policies and directives on the national and also European level.

(Table 1) Benthic foraminifer stratigraphy of ODP Site 166-1006 sediments

Site 1006 provides a middle to late Miocene record of bathyal benthic foraminiferal abundance changes in the Straits of Florida. Benthic foraminifers indicate that sedimentation was primarily in situ at Site 1006, with periods of increased downslope transport of shallow-water material. Changes in the in situ faunas may have resulted from circulation changes. Dissolution indices identify a dissolution interval in the upper Miocene section at Site 1006 that may correspond to isotope event Mi5. The data presented here are intended to support a subsequent study (M.E. Katz, J.D. Wright, and K.G. Miller, unpubl. data) that integrates the benthic foraminiferal faunal record with the stable isotopic record, all within a sequence stratigraphic framework. The ultimate goal is to demonstrate that the Miocene faunal and isotopic changes at Site 1006 reflect global, regional, and local influences, and provide constraints on paleobathymetry, sediment provenance, and circulation changes that may reflect changing source regions and glacioeustatic changes.

Pliocene benthic foraminiferal abundances of ODP Hole 105-646B from north Atlantic

Our benthic foraminiferal data clearly indicate eight layers of deep-water turbidites during the Messinian (MTL 1-8) and one in the early Pliocene (PTL 1) in Ocean Drilling Program Leg 105, Site 646B. These deep-water tuibidite deposits are characterized by highly concentrated agglutinated marsh benthic foraminifera (e.g., Trochammina cf. squamata, Ammotium sp. A, Miliammina fusca), rounded quartz, polished thick-walled benthic foraminifera, wood fragments, plant seeds, plant fruit, and highly concentrated mica and are interbedded with sediments containing deep-water benthic faunas. We suggest these turbidites deposited during sea-level low stands (approx. 80-100 m below sea level), and their ages are tentatively correlated to 6.59, 6.22, 6.01, 5.89, 5.75, 5.7, 5.65, 5.60, and 5.55 Ma, respectively, based on the Messinian oxygen isotope enrichments at Site 552A of Deep Sea Drilling Project Leg 81. The turbidites layers during the late Messinian, coeval with frequent climate changes suggested by six oxygen enrichment excursions of Site 552A, may have been in part linked to the late Messinian evaporite deposits in the Mediterranean Basin. The most profound climate changes at 5.75 and 5.55 Ma may have been related to the Lower and Upper Evaporites in the Mediterranean Basin.

Pliocene-Pleistocene distribution of benthic foraminifers from ODP Hole 110-672A (Table 2)

Site 672 is located on the Atlantic abyssal plain to the east of the Lesser Antilles forearc region. It serves as a stratigraphic reference section for sediments entering the Barbados accretionary prism. A relatively complete Pliocene through lower Pleistocene section was recovered from Site 672 that contains a moderately well-preserved population of benthic foraminifers. Q-mode factor analysis of the benthic population data identified three Pliocene-Pleistocene assemblages that inhabited this site. The Factor 1 fauna, characterized by Nuttallides umboniferus, is commonly associated with the presence of Antarctic Bottom Water (AABW). The Factor 2 assemblage is characterized by Globocassidulina subglobosa, Epistominella exigua, and a combined category of unilocular species. The Factor 3 assemblage is characterized by Epistominella exigua, and Planulina wuellerstorfi. The Factor 2 and 3 faunas are associated with bottom water significantly warmer than that preferred by the Factor 1 assemblage. The distribution of these assemblages has been used to distinguish three climatic intervals in the abyssal environment during the Pliocene-Pleistocene. An early Pliocene warm interval occurred from the Ceratolithus rugosus Subzone to the middle of the Discoaster tamalis Subzone. The upper Pliocene is characterized by oscillations between the Factor 1 and Factor 2 assemblages, which suggests climatic deterioration and increased pulses of AABW flow. The persistence of an essentially modern (Factor 1) fauna throughout the early Pleistocene suggests full glacial development at both poles and a substantial volume of AABW production.

Modes of vector transmission of Cherry leaf roll virus (CLRV) - molecular basis and potential arthropod vector species

Cherry leaf roll virus (CLRV) is a plant pathogen of economic and ecologic importance. It is globally distributed in a wide range of forest, fruit, and ornamental trees and shrubs. In several areas of cherry and walnut production CLRV causes severe losses in yield and quality. With current reference to the rapid dissemination and strong symptom expression in Finnish birches and the Germany-wide distribution of CLRV in birches and elderberry, we continuously investigate and gradually reveal CLRV transmission pathways as by pollen, seeds or water. However, modes and interactions responsible for the wide intergeneric host transmission as well as for the exceptional CLRV epidemic in Fennoscandia still remain unknown. In this project systematic studies shall investigate biological vectors as a causal agent to finally derive control mechanisms and strategies to avoid new epidemics in different hosts and geographic regions. Detailed monitoring of the invertebrate fauna of birch stands/forests and elderberry plantations in Germany and Finland shall reveal potential vectors to subsequently study them in detail by approved virus detection methods and transmission experiments. Molecular analyses of the CLRV coat protein shall prove its role as a viral determinant for a virus/vector interaction. Consequently, this project essentially will contribute important answers on the CLRV epidemiology, and this will be a key element within the first network of research on plant viral pathogens in forest trees.

Umwelt - und Fauna-Flora-Habitat-Verträglichkeit im Rahmen des Genehmigungsverfahrens nach Paragraph 7 Abs. 3 des Atomgesetzes zum Abbau des Versuchskernkraftwerks AVR in Jülich

Das Öko-Institut wurde vom Ministerium für Wirtschaft, Mittelstand und Energie des Landes Nordrhein-Westfalen mit der Begutachtung der Umweltverträglichkeit und der Fauna-Flora-Habitat-Verträglichkeit für den Rückbau des Versuchskernkraftwerks AVR in Jülich beauftragt. Das Gutachten des Öko-Instituts soll der Genehmigungsbehörde gemäß Paragraph 1a AtVfV die Beurteilung ermöglichen, ob durch den Abbau des AVR bedeutsame Auswirkungen auf die Schutzgüter Menschen, Tiere, Pflanzen, Boden, Wasser, Luft, Klima, Landschaft, Kulturgüter und sonstige Sachgüter sowie Wechselwirkungen zwischen den vorgenannten Schutzgütern zu besorgen sind.

Oekologische Analyse eines Naturschutzgebietes

Das Schweinsberger Moor (Naturschutzgebiet) liegt in einer Senke inmitten landwirtschaftlicher Flaeche. Es werden Pflegemassnahmen diskutiert, die zu einer Erhoehung seines Wertes als Naturschutzgebiet beitragen sollen. Kenntnisse ueber das Moor gibt es aber nicht. Wir machen: Wasserhaushalt ueber mehrere Jahre; Aenderungen der Vegetation (Ausbreitung Seggenwiesen, Schilfguertel, Weidenzone, Gewaesser) im Laufe der Jahre; Analyse der Tierwelt (insbesondere in der natuerlichen Monokultur der Phragmites-Zone) von wasserbewohnenden Wirbellosen ueber Insekten bis zu Saeugern und hoffen so eine Basis fuer Planungsunterlagen zu erhalten. Dazu versuchen wir, den Einfluss der umliegenden Landwirtschaft zu analysieren (Eutrophierung?).
