| Abstract |
A quantitative study was made on the ecology of halacarid mites in tidal beaches on the isle of Sylt (North Sea) and in the Tromsö area in Northern Norway, and in a non-tidal beach at Schilksee (Kiel Bay). Of the 23 species observed, Actacarus pygmaeus, Anomahalacarus minutus, Halacarellus capuzinus, H. procerus, H. subcrispus, H. subterraneus, and Agauopsis spinosa were dominant. The horizontal and vertical distribution of these species in the sandy beaches is described. On the whole, the halacarid fauna of the three areas is fairly similar. Several species are found in two of the three areas or even in all of them. In these cases, their distribution within the beaches is broadly similar. The main difference between the three areas is caused by the nearly complete (Schilksee) or complete (Tromsö) lack of Actacarus pygmaeus, the dominant species at Sylt. The larger number of species observed in Northern Norway is due to immigrants from other habitats. A comparison is made between the halacarid fauna of the area under study and that of warmer seas. At the European shores, the genus Halacarellus is represented by numerous species; it seems to be absent in tropical waters. In none of the species studied, the period of reproduction is limited; they all seem to reproduce during all of the year. |
