| Abstract |
This contribution compares oribatid mite communities in salt marshes from Northern Germany (Sylt and Meldorf), Northern Portugal (Aveiro) and Southern Portugal (Faro), regarding the species composition and their dominance structures. Similar to the vertical zonation of the vegetation in the sites, the mite show characteristical vertical changes each. Yet, there is a more or less constant halophilous species stock in all regions, with Ameronothrus schneideri, Zachvatkinibates quadrivertex and Hermannia pulchella. Additional species characterize the median or upper salt marsh zones,contrasting between the three regions. The patterns of oribatid mite communities support biogeographical and ecological interpretations. As main factors the regional climate, the regional vegetation structure, the regular marine inundation and the substrate salinity are assumed. |
