    Notes: [Auszug] IN reconstructing the Saldanha skull-cap (see Nature, 172, 791 ; 1953), a few small fragments were temporarily left out, because we did not have all the pieces necessary to complete the 'jig-saw puzzle'. Among these fragments was part of the ramus of a mandible with the coronoid process on it; but ...

    Die akuten arteriellen Zirkulationsstörungen (Organopathie) und ihre Beziehungen zu neurovegetativen Kreislaufstörungen (1956)

    Notes: Zusammenfassung Ich glaube somit gezeigt zu haben, wie gerade die Beeinflussung der gestörten Regulation an den kleinsten Arterien einen überragenden Einfluß auf den Erkrankungsverlauf der akuten Durchblutungsstörungen und deren Folgeerscheinungen ausübt. Dabei dienten nachteilige äußere Einwirkungen oder eine unüberlegte medikamentöse Behandlung und die dadurch vermehrte neurale Sperre an den kleinsten Gefäßen ebenso als Beweismittel wie die, bei sorgfältiger Beobachtung erkennbare, allmähliche Lösung des Krampfzustandes unter dem Einfluß einer der Krankheitsphase (um mitSunder-Plassman und Mitarbeitern zu sprechen) angepaßten Therapie.

    Notes: Abstract Hummingbird pollination is documented for a natural population ofStenorrhynchos lanceolatus Aublet. L. C. Rich. occurring in Rio de Janeiro State, southeastern Brazil. At the study site the plants are pollinated byPhaethornis eurynome (Phaethorninae),Thalurania glaucopis (females only) andLeucochloris albicollis (Trochilinae). The plants offer nectar as a reward and the pollinaria become stuck to the surface of the hummingbird's bill while it is probing the flowers. The orchid population received a few (0–4) hummingbird visits per day, with about 83% of the flowers being pollinated. In spite of the low frequency of visits, the granular structure of the pollinarium plus the behaviour of the most frequent pollinators, which tend to visit all the fresh-looking flowers of each inflorescence, a very high fruiting success was promoted. Experimental evidence suggests that the pollinaria may remain up to 6.30 hours on the hummingbird's bill, enhancing the chances of cross-pollination and long-distance pollen flow.
