“…The last substantial land bridge to Hokkaido was present during the Würm sea level lowering approximately 20,000 years BP [33] . According to some authors [32] , [34] , [35] a land bridge also existed between Kyushu and the Korean peninsula during this time ( Figure 3 ). Assuming that during this period was the most recent possibility for genetic exchange between the Japanese and the mainland populations of Epiophlebia, it also follows that their distribution was significantly different from the present one.…”

Unusual biogeographic patterns of closely related groups reflect events in the past, and molecular analyses can help to elucidate these events. While ample research on the origin of disjunct distributions of different organism groups in the Western Paleartic has been conducted, such studies are rare for Eastern Palearctic organisms. In this paper we present a phylogeographic analysis of the disjunct distribution pattern of the extant species of the strongly cool-adapted Epiophlebia dragonflies from Asia. We investigated sequences of the usually more conserved 18 S rDNA and 28 S rDNA genes and the more variable sequences of ITS1, ITS2 and CO2 of all three currently recognised Epiophlebia species and of a sample of other odonatan species. In all genes investigated the degrees of similarity between species of Epiophlebia are very high and resemble those otherwise found between different populations of the same species in Odonata. This indicates that substantial gene transfer between these populations occurred in the comparatively recent past. Our analyses imply a wide distribution of the ancestor of extant Epiophlebia in Southeast Asia during the last ice age, when suitable habitats were more common. During the following warming phase, its range contracted, resulting in the current disjunct distribution. Given the strong sensitivity of these species to climatic parameters, the current trend to increasing global temperatures will further reduce acceptable habitats and seriously threaten the existences of these last representatives of an ancient group of Odonata.

“…In general the water level in the oceans and also on the coasts has risen more than 100 m since the maximum of the last ice age about 20,000 years ago, when huge masses of water were stored in large ice-covered areas. The steepest increase amounted to 2 m per century (2 cm/a) (5) (12) (18) (10). This rise was caused primarily by the melting of the ice and the subsequent increase of the water volume in the ocean.…”

The development of MThw on the German North Sea coast is probably related to the development of the climate. Other important contributing factors are discussed. For the last 20 years a relatively steep rise of MThw level is recognizable. An even steeper rise as a result of climate changes appears possible within the next 100 years. With regard to the great importance for coastal engineering, the necessity of attentive observation and international cooperation among different scientific disciplines is stressed.
