    Notes: Abstract This paper briefly reviews the changes which have occurred in the past three hundred years in the public's attitudes toward our Nation's natural resources, particularly the wildlife resources. It discusses how these changing attitudes have contributed to today's surface coal mine reclamation laws which require that the disturbed land be restored to a level of productivity equal to or greater than that which occurred before mining. This paper stresses the need to manage each reclamation site on an ecosystem basis, recognizing the interrelationships of all the resource components. This paper emphasizes both the fundamental importance of the holistic approach to mine site reclamation and the responsibility that the wildlife biologist has to see to it that wildlife habitat considerations are incorporated into each phase of the reclamation plan. Brief management considerations are given to three unique reclamation habitat types; riparian, agriculture and forest.

    Description / Table of Contents: Transition Metal Carbyne Complexes, LII. (Tricarbonylchromium)-η6-phenyl as Substituent in Carbene- and Carbyne Complexes of the VI. SubgroupThe reaction of tricarbonyl(η6-phenyllithium)chromium with the metalhexacarbonyls of the VI. subgroup and subsequent alkylation by triethyloxonium tetrafluoroborate yields pentacarbonyl-{ethoxy[(tricarbonylchromium)-η6-phenyl]carbene} complexes of chromium, molybdenum, and tungsten (1 - 3). 1 and 3 react with boron trihalides BX3 (X = Cl, Br) by cleavage of the ethoxy group to form trans-tetracarbonylhalogeno[(tricarbonylchromium)-η6-phenylcarbyne]metal complexes 4 - 7. Properties, spectroscopic results, and the X-ray structure analysis of 6 are discussed.
    Notes: Die Umsetzung von Tricarbonyl(η6-phenyllithium)chrom mit den Metallhexacarbonylen der VI.

    Description / Table of Contents: Zusammenfassung Angesichts fehlender Information über die kommerzielle Verfügbarkeit in Europa von Biopräparaten (auf der Basis von Mikroorganismen einschl. der Viren) und von nützlichen Metazoen für biologische Maßnahmen zur Unterdrückung von Schadorganismen wurde an die amtlichen Stellen, ausnahmsweise an Einzelexperten in folgenden Ländern eine Umfrage gerichtet: Frankreich, Großbritannien, Italien, Österreich, Rumänien, Jugoslawien, Schweden, die Schweiz, die Niederlande, Finnland und Bundesrepublik Deutschland. Die Ergebnisse werden in 2 Teilen als ein Momentbild des Zustandes Anfang 1984 vorgelegt. Im Begleittext wird für die Annahme einer Europäischen Zulassungsordnung für Biopräparate plädiert (die als Entwurf bereits vorliegt), um Zeit und Geld zu sparen. Zwischen den einzelnen Ländern bestehen sehr große Unterschiede bezüglich der Verfügbarkeit biotischer Agentien für biologische Verfahren. Einige vielversprechende neue Entwicklungen werden kurz in der Hoffnung vorgestellt, daß sie stimulierend wirken. Allen Kollegen, die bei der Umfrage geholfen haben, sei besonders gedankt.
    Notes: Abstract In view of the lack of information concerning the commercial availability in Europe of biopreparations (based on microorganisms including viruses) as well as of beneficial metazoa for biological control of pest organisms, an inquiry was started for the following countries: France, Great Britain, Italy, Austria, Rumania, Yugoslavia, Sweden, Switzerland, the Netherlands, Finland and Germany Fed. Rep. Results are presented as a momentary picture of the situation in early 1984. A plead is made for the acceptance of an European protocol for registration of biopreparations (which has already been drafted) in order to save money and time. There are great differences between countries in the availability of biotic agents for biological control. Some very promising new developments are briefly reviewed and considered to act in a stimulating way. Thanks are due to those colleagues who helped to obtain the information here presented.

    Description / Table of Contents: Zusammenfassung Eine im Auftrag der Gesellschaft für Technische Zusammenarbeit (GTZ) durchgeführte forstliche Reise nach Nordchina gab Anlaß, über einige der dabei erhaltenen Eindrücke und Kenntnisse zu berichten. Nach einer kurzen Darstellung der forstlichen Ausgangslage wird eine Übersicht über die wichtigsten beobachteten oder von chinesischer Seite aus erwähnten Schadinsekten, Schadwirbeltiere und Waldkrankheiten gegeben. Die Abwehrmaßnahmen im Rahmen des Waldschutzes umfassen in erster Linie chemische Bekämpfungen, ferner Kulturverfahren und, in steigendem Maße, biologische Methoden. Bei der Verwendung von Nutzorganismen wird besonders eingegangen auf den Einsatz vonTrichogramma dendrolimi gegen den Kiefernspinner (Dendrolimus-Arten), die Erprobung von zwei Schlupfwespen-Arten,Scleroderma sp. undSchreineria sp., gegen den Kleinen Pappelbock (Saperda populnea) sowie die Ansiedlung insektenfressender Vögel und die von Wieseln gegen Wühlmäuse. Ferner werden Angaben zur mikrobiologischen Bekämpfung von Schadinsekten mit insektenpathogenen Viren, Bakterien und Pilzen gemacht sowie abschließend einige Forschungsprojekte über den Einsatz von Antagonisten gegen phytopathogene Erreger vorgestellt.
    Notes: Abstract A visit to Northern China's forests on behalf of the German Agency for Technical Cooperation (GTZ) gave us the opportunity to report on some impressions. After a short description of the forestry situation overthere, a survey is given on the most important pest insects, vertebrates, and forest diseases, based on personal observations as well as on Chinese reports. Defense measures for forest protection include mainly chemical control, also silvicultural control, and recently more and more biological methods. In the report on the use of beneficial organisms, main emphasis is placed on the utilization ofTrichogramma dendrolimi to suppress the pine caterpillar (Dendrolimus spp.), the experimental use of two hymenopterous parasites,Scleroderma sp. andSchreineria sp., against the poplar borer (Saperda populnea) as well as the colonization of insectivorous birds and of weasels to suppress voles. It is also reported on the microbial control of pest insects using insect pathogenic viruses, bacteria, and fungi. Finally, some research projects on the use of antagonists against phytopathogens are mentioned.

    Description / Table of Contents: Reaction of Metal and Metalloid Compounds with Polyfunctional Molecules, XXXIII. The Reaction of Propargylamines and N-Organyl-N-(trimethylsilyl)propargylamines with Boron-Halogen and Boron-Sulfur CompoundsThe N-organyl-N-(trimethylsilyl)propargylamines 1-5 are obtained from N-organylpropargylamines with chlorotrimethylsilane and triethylamine. The reaction of 1-5 with halogenoboranes, organylhalogenoboranes, or methylbis(methylthio)borane leads to the (organylpropargylamino)boranes 6-13. On the other hand, in the reaction of N-organylpropargylamines with halogenoboranes the C≡C triple bond inserts into the halogen-boron bond and yields the 1-azonia-2-borata-3-cyclopentene system 14-19 by intramolecular coordination. N-Organyl-N(trimethylsilyl)propargylamines react with bromodimethylborane in the molar ratio 1:2 under elimination of trimethylborane to give the 1-aza-2-bora-3-cyclopentene ring system 20-24. In the reaction of N-organyldipropargylamines with halogenoboranes both C≡C triple bonds insert into boronhalogen bonds to form the 1-azonia-5-boratabicyclo[3.3.0]octa-3,6-diene system 25-38. Tripropargylamine reacts with trichloro- and tribromoborane under three-fold insertion and intramolecular coordination to yield the 3,7,10-trihalogeno-1-azonia-5-boratatricyclo[3.3.3.01,5]undeca-3,6,10-trienes 39 and 40. For 39 the X-ray structure is reported.
    Notes: N-Organyl-N-(trimethylsily)propargylamine (1-5) werden aus N-Organylpropargylaminen mit Chlortrimethylsilan unter Zusatz von Triethylamin dargestellt. Die Reaktion von 1-5 mit Halogenboranen, Organylhalogenboranen bzw. Methylbis(methylthio)boran führt zu den entsprechenden (Organylpropargylamino)-boranen 6-13. Bei der Umsetzung der nicht silylierten N-Organylpropargylamine mit Halogenboranen erfolgt dagegen Einschiebung der C≡C-Dreifachbindung in die Halogen-Bor-Bindung und intramolekulare Koordination zum 1-Azonia-2-borata-3-cyclopenten-System 14-19. N-Organyl-N-(trimethylsily)propargylamine reagieren mit Bromdimethylboran im Molverhältnis 1:2 unter Abspaltung von Trimethylboran zum 1-Aza-2-bora-3-cyclopenten-Ring 20-24. Bei der Umsetzung von N-Organyldipropargylaminen mit Halogenboranen erfolgt Einschiebung der beiden C≡C-Dreifachbindungen in zwei Bor-Halogenbindungen wobei das 1-Azonia-5-boratabicyclo[3.3.0]octa-3,6-dien-Ringsystem 25-38 entsteht. Tripropargylamin reagiert mit Trichlor- bzw. Tribromboran unter dreifacher Einschiebung und intramolekularer Koordination zum 3,7,10-Trihalogen-1-azonia-5-boratatricyclo[3.3.3.01,5]undeca-3,6,10-trien-System 39 und 40. Für 39 wird die Röntgenstruktur mitgeteilt.

    Notes: The configurational isomers of astaxanthin (3,3′-dihydroxy-β,β-carotene-4,4′-dione) from the flesh of salmon (Salmo salar and Oncorhynchus) caught at different places in Europe and Canada were isolated and analyzed as (-)-camphanic acid diesters by means of HPLC. The biological variation in the composition of the configurational isomers in seven fish was surprisingly similar: 78 to 85% of (3S, 3′S)-astaxanthin, 12 to 17% (3R, 3′R)-astaxanthin and 2 to 6% meso-astaxanthin.
