»Studieren Sie die Rhythmen«- zum Gedenken an Gunther Hildebrandt
Jahresrhythmus und Schilddrüsenfunktion unter besonderer Berücksichtigung des Morbus Basedow
Annual rhythm and thyroid function with particular reference to Grave’s disease
Turning points in the biological year are not identical to those of the cosmic-geophysical year. The ascending half of the biological year (February to August) is marked by an ergotropic tendency for vegetatively autonomous regulation. Correspondingly, in… Read More
Chronobiologische Aspekte der Schmerzempfindung
Chronobiological aspects of pain sensation
It has been known for a long time that sensation of pain shows large variations. The first systematic investigations were carried out at the beginning of the 20th century. Principally, pain intensity can be influenced by sensitivity changes of the nociceptors in peripheral tissue and by… Read More
Die Zunahme morphologischer und physiologischer Autonomie bei den Volvocales
The increase of morphological and physiological autonomy with the Volvocales
The transition to multicellularity in early evolution led to an emancipation from the environment and to an increase of organismal autonomy. As a model for this principle, the Volvocales are studied. Within the green algae a sequence from single celled forms to… Read More
Das Geheimnis der Armleuchteralgen (Characeae)
The secret of candelabra algae (Characeae)
Candelabra algae (Characeae) belong to the most endangered fresh water plants. In deep lakes they need very clear water, poor in nutrients. In shallow water regular mechanical disturbances are necessary to protect their existence because Characeae are pioneering vegetation in such places. This… Read More
Von Bärlappen, Mondrauten und Natternzungen
Clubmosses, grape-ferns and Adder’s-tongue ferns
The clubmosses (Lycopodiaceae), grape-ferns (Botrychium) and Adder’s-tongue ferns (Op/aioglossum) are rclatively rare groups of pteridophytes in the European flora. Here we help to analyze the different species in the field as well as to grasp the obvious coherence of these differences.… Read More
Zur Begriffsbildung für die funktionellen Gruppen organischer Stoffe aus biologischen Prozessen
Concerning a conception of functional groups based on biological processes
The functional groups of classical organic chemistry prove highly suited for classification purposes when their various process potentials are taken from the living world. Such a classification harbours information which accords better with the facts; we need… Read More
Der Flüssigkeitsorganismus des Menschen, seine Organe und Organfunktionen als Grundlage des Fühlens
The fluid organization of man, his organs and organ functions as a basis of feeling
The rhythmical organization of the human being comprises a co-operation of the fluid organism with breathing. The fluid organism is developed by a central arterial pressure system and a venous flow system open to the periphery. This represents the basis… Read More
Die Eischalen-Strukturen der Reptilien als ein Bild tierischer Konstitution
The egg shell structures of reptiles as a picture of the animal's constitution
The articles on bird egg shells in the Tycho de Brahe yearbooks 1996 and 1997 are here supplemented with an article on reptile eggs which also reviews the situation with the birds.
The poikilothermic reptiles mostly bury their predominantly colour… Read More
