    Description / Table of Contents: Zusammenfassung Von der anliegenden Erdhügeln den 5 weitverteilenden Termitengattungen, die an 2 Lagen nach dem Süd und Südwest von Townsville, nord Queensland, sind, sind die Verwandschaften untersucht worden. Es ist gezeigt worden, dass 4 diesen Gattungen, nämlichAmitermes laurensis (Mjöberg),Tumulitermes pastinator (Hill),Drepanotermes rubriceps (Froggatt) undDrepanotermes perniger (Froggatt) polycalisch sind, worin eine einzige Kolonie bis 8 Erdhügeln enthält. Eine enfache unzweideutgie Methode gebrauchte wurde. Ein Köder, der einen radioactiveren (131I) Indikator enthielt, in einem Erdhügel eingeführte wurde, dann wurde die nachfolgende durch Termiten nach anderen Erdhügeln Ubertragung diesem Köder mit einen Szintillationsdetektor kontrolliert. Die Darstellung der Erdhugelverteilungs — tatsachen verhandert ist dadurch, dass zwischen einigen australienischen Termitenkolonien gibt es die polycalischen Erdhügeln. Im einzelnen, kann die überzerstreuung der Erdhügeln für einigen gattungen als Indikation der innenspecifischen Mitbewerbung, nicht erklärte wird, wenn die Lagen der polycalischen Erdhügeln unbekannt wird.
    Notes: Summary The relationships of adjacent mounds of five widely distributed species of termites, at two sites south and southwest of Townsville in north Queensland have been examined. It has been shown that four of these species,Amitermes laurensis (Mjöberg),Tumulitermes pastinator (Hill),Drepanotermes rubriceps (Froggatt) andDrepanotermes perniger (Froggatt), are polycalic, with up to eight mounds comprising a single colony. A simple unequivocal method was used. A bait containing a radioactive tracer (131I) was introduced to a mound and the subsequent transfer of this bait to other mounds by termites was monitored with a scintillation detector. The existence of polycalic mounds among some Australian termite colonies alters the interpretation of mound distribution data. In particular, overdispersion of the mounds of some species cannot be interpreted as indicating intraspecific competition if the locations of polycalic mounds are unknown.

    Notes: Abstract Termites are more abundant in the warmer lower latitudinal regions of the earth. Within these broad geographic regions, however, the precise nature of the factors influencing termite abundance is poorly understood. In this paper I have examined the abundance of detritivorous, mound-building termites and certain aspects of the climate, soils and vegetation at 14 sites in tropical northeastern Australia. No relationship between termite mound density and the particle-size characteristics of surface soil horizons, plant available phosphorous or rainfall was found. Microbial biomass carbon level of the surface soil was found to have a strong negative relationship with termite mound numbers. The negative interaction between the soil microbial population and termites may be due to the limiting effect of the organic matter processing capacity of the soil microbial population on the success of termites in occupying the decomposer niche in any particular area. Microbial biomass may therefore be a major factor influencing termite abundance in tropical Australian landscapes and elsewhere.

    Notes: Abstract  As part of a broader study, the aim of which is to identify soil factors that might be associated with yield decline of sugar cane, microbial biomass and protease activities were examined in soil samples collected from seven paired old and new land sites in three cane-growing districts of north Queensland. No consistent changes in soil protease activities were observed, although some sites exhibited specific effects, as a result of extensive periods of sugar cane monoculture. Soil microbial biomass, however, was significantly lower in those soils where sugar cane had been grown for extended periods. The implications of a lowering of soil microbial biomass on sugar cane yields and sustainability are discussed.

    Notes: Schlußfolgerung [J]E wird spezifisch in ER-reichen Geweben konzentriert. Die Anreicherung ist szintigraphisch nachweisbar und erlaubt die Darstellung von ER in Primärtumoren und Metastasen. Die rasche metabolische Akkumulation in der Leber und Ausscheidung in den Darm sind hinderlich. Die bisherigen Ergebnisse ermutigen aber zur Fortsetzung der Untersuchungen mit der berechtigten Hoffnung auf die Möglichkeit einer szintigraphischen in-vivo Bestimmung von ER in Mammakarzinomen und Metastasen.

    Notes: Schlußfolgerung - Erhöhte Serumspiegel des p185erbB-2 Onkoproteins können mit einem EIA bei einzelnen Ovarialkarzinompatientinnen gemessen werden. - Wegen des seltenen Vorkommens versprechen p185erbB-2 Serumkonzentrationen keinen klinischen Nutzen bei der Identifikation oder Verlaufskontrolle von high-risk Patientinnen.
