摘要

在贝加尔湖东北2100公里的雅库特湖、沃罗塔湖和拉宾基尔湖北部，我们发现了一种公认的贝加尔湖特有物种林达维亚。形态分析和非度量多维尺度分析表明，雅库特湖和外白卡利亚湖的微小L.minuta种群属于同一（形态）物种。讨论了可能的扩散历史。最可能的假设是，L.minuta在几个更新世冰川周期期间存在于贝加尔湖流域，由于贝加尔湖以前与勒纳河相连，因此该河中可能有稳定的该物种种群，并且该河将一些细胞带到了其他合适的栖息地。在冰川期，L.minuta也可能在几个冰坝湖泊中存活更长时间，并可能向东北方向进一步扩散到雅库特的湖泊。

Finding of a putative Lake Baikal endemic, Lindavia minuta, in distant lakes near the Arctic pole in Yakutia (Russia)

In the northern lakes of Yakutia, Vorota and Labynkyr, which are 2100 kilometres northeast of Lake Baikal, we found a putative Lake Baikal endemic, Lindavia minuta. Morphological analysis and non-metric multidimensional scaling showed that L. minuta populations from Yakutian and Transbaikalian lakes belong to the same (morpho) species. The possible dispersal history is discussed. The most probable hypothesis is that L. minuta was present in the Baikal basin during several Pleistocene glaciation cycles, and since Lake Baikal was previously connected to the River Lena, it is possible that there was a stable population of this species in the river, and that the river carried some cells to other suitable habitats. During glaciated periods, L. minuta could also have survived for longer periods in several ice dam lakes and possibly dispersed further north-east to the lakes in Yakutia.

期刊介绍： Diatom Research is the journal of the International Society for Diatom Research. The journal is published quarterly, in March, June, September and December, and welcomes manuscripts on any aspect of diatom biology. In addition to full-length papers, short notes and reviews of recent literature are published which need not contain all the sections required for full-length papers; we see these as being necessary to record information which is of interest but which cannot be followed up in detail. Discursive “Opinion” papers are encouraged which would not necessarily follow the normal lay-out. If extremely long papers are to be offered, the author(s) should contact the editors first to discuss any problems. Book reviews, obituaries and meeting reports can be published. All papers will be subject to critical review by the editors and referees, as appropriate to their content. Papers will be accepted in English only.
