Habitatselektion und Habitatbindung der Simuliiden (Simuliidae, Diptera) und ihre Bedeutung für den Erhalt (Wiederherstellung) naturnaher Fließwasserstrukturen
[Selection and binding to specific habitats by blackflies and the significance there of for the preservation or re-establishment of near-natural bodies of running water]

Abstract: The choice of locality for the deposition of eggs by blackflies is given for a number of species (among them Simulium costatum FRIEDER., S. nölleri FRIEDER, S. ornatum MG. and Prosimulium tomosvaryi (END.). The females react to changes in the environment of running waters, whether the changes are due to the dynamics of the body of water or the influence of man. Evidently the signals associated with the structures of the habitat or subhabitat are the factors which lead towards the orientation and selection of habitat by each species. Are certain signals (characters) absent, then the eggs will not be recognised and a colonisation of the water through eggs will not take place. Reference pictures, specific to certain natural environments, types of running waters, ecological and habitat models or patterns developed for practical application, are compared and contrasted. Reference is also made to the special importance of invariable signal factors, which have not been specially influenced so far through the activities of man in the vicinity of running waters. It is thought that current pattern belong to such invariable structures. It is recommended that a more thorough analysis of the habitat patterns of individual species be made, so that bodies of running waters can be either specifically protected or re-naturalised with theses species in mind.
