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
Hygiogenese und Salutogenese Versuch einer (notwendigen) Begriffsdifferenzierung
Hygiogenesis and salutogenesis - an attempt at a (necessary) differentiation of concepts
The concepts salutogenesis and hygiogenesis originate from different basic considerations. Hygiogenesis means a systematic representation of autonomous regulations in the sense of a therapeutic physiology. Salutogenesis, however, represents a system… Read More
Über Methoden zur Erforschung hygiogenetischer Prozesse
On research methods of hygiogenetic processes
The processes bringing about health after illncss may be considered as metamorphoscs of those processes which generally enable health. As rhythm is one of the most essential conditions of life, we speak of hygiodynamics (maintenance of health) and hygiogenesis (healing) respectively. So… Read More
