<paragraph pageId="0" pageNumber="1">Three ecological groups can be recognised among the recorded species:</paragraph>
|
||
<paragraph pageId="0" pageNumber="1">Species widely distributed in the Holarctic and living also at sites distant from the lake shore (notated as W in Appendix 1). This group mostly consists of xerophilic and steppe species (e.g., F. parvulus, A. stebayevae, A. mongolicus, F. mongolica sp. nov.) which occur also on neighbouring arid landscapes of continental Asia. They often prefer saline lands and penetrate to catenas of saline lakes where they can be numerous. The group also include widely distributed eurytopic (P. notabilis, P. minima) and ruderal species (P. minuta). The latter species can be very abundant in lower part of catenas.</paragraph>
|
||
<paragraph pageId="0" pageNumber="1">Lake species (as L in Appendix 1). This group consists of species found so far only in lake shores. They mostly belong to the fauna of Lake Baikal (P. barathrum sp. nov., S. acorrelata, S. baica, S. robustodens, P. appressopilosa, P. baicalica sp. nov.). Folsomia uniramia presumably belongs to the group since it has been recorded only in dunes at this lake shore. S. acorrelata and P. appressopilosa also occur in shore of saline Alginskoye Lake which is close to Baikal Lake. Considering salt-lake catenas, E. buryatica sp. nov. is only species which belongs to this group.</paragraph>
|
||
<paragraph pageId="0" pageNumber="1">Hygrophilic widely distributed species (as H in Appendix 1). In our materials, Isotomurus stuxbergi (Tullberg, 1876) is the only member belonging to this group. It was found once in the Baikal shore.</paragraph>
