Gislen T (1944) Zur Verbreitung und Oekologie von Rhynchodemus terrestris (O.F. Müller) mit Bemerkungen über Bitemporalität. Arch. f. Hydrobiol. 40(3): 667-686 |
Abstract / Notes
The sp. is the most frequent one among the terrestrial triclads, occurring in Denmark, s. Sweden and the British Isles as well as in s. Germany, the Balkans and in the Pyrenees, but there is a void in the n. German lowlands, due evidently to the continental summer climate that intensifies the dryness of the sandy ground. Near Lund R. terrestris was associated with many Gastropoda and Collembola. It is supposed that the sp. feeds chiefly on the latter. Propagation seems to occur from May to September; it probably hibernates in the southern parts of its area. In late spring and in autumn the sp. may be found in the upper layers of the ground, in summer and in winter it descends into deeper strata according to humidity of the habitat. A sp. behaving in that way is called ' 'bitemporal". With regard to the age they reach, perennial, annual, hiemal and estival bitemporal types may be distinguished among the cryptozoic fauna.
