    Notes:
    [Auszug] Two cloned trypanosome populations (247-L and 386AA) were fed, either separately or as an equal mixture, through a membrane to different groups of tsetse flies (see Fig. 1). Flies showing the presence of metacyclic-stage trypanosomes (indicating completion of full cyclical development) were allowed ...

    Notes:
    Abstract Peachtree borer (PTB) cocoons, peach tree bark, and a mixture of frass and gum obtained arount PTB wounds were extracted with organic solvents of increasing polarity. Female PTB moths,Synanthedon exitiosa (Say), laid the greatest number of eggs on filter paper substrates treated with acetone extracts of PTB cocoons, ethyl acetate extracts of peach tree bark and acetone extracts of frass and gum mixtures. The extracts of cocoons or frass and gum mixture were separated by liquid chromatography and thin layer chromatography.

    Description / Table of Contents:
    Summary 1. Rates of net photosynthesis and respiration were determined in situ forTridacna and coral species and their contained zooxanthellae at depths from 9 to 18 m. 2. Integrated daily total net photosynthesis to respiration ratios (P/R ratio) were calculated from these data to obtain the potential contribution of algal photosynthesis to the energy budget of the coral-algal symbiotic association. 3. The integrated daily P/R ratios varied between 0.79 and .89. Maximum ratios of photosynthesis to respiration rates ranged from 1.15 forMussa arrgulosa to 2.91 forManicina areolata. 4. Similar measurements were made on mixed benthic communities off southeastern Florida (USA) in a clean, unpolluted area and in an area influenced by the effluent of Biscayne Bay (USA). Very significant differences were found.
    Notes:
    Kurzfassung Im Rahmen mehrerer amerikanischer Unterwasser-Forschungsprogramme wurden Stoffwechseluntersuchungen in verschiedenen Korallenriffen an Benthostieren durchgeführt, die in symbiotischer Partnerschaft mit Zooxanthellen leben. An Korallen- undTridacna-Arten wurden in situ die Beziehungen zwischen Nettophotosynthese und Sauerstoffverbrauch (P/R-Verhältnis) gemessen. Als Maximalwert wurde beiManicina areolata ein P/R-Verhältnis von 2,9 ermittelt. Die auf einen Zeitraum von 24 Stunden bezogenen Durchschnittswerte lagen zwischen 0,79 und 0,89. Es wurde festgestellt, daß die photosynthetische Aktivität der Korallen in verunreinigten Riffgebieten stark absinkt.
