摘要

barbatus Lychnothamnus （Charophyceae, chareae）是世界上最罕见的宏观蕨类孑遗物种之一，具有明显的分离范围，在北亚的化石遗骸中已经发现了很长时间。在西伯利亚南部Minusinsk森林草原（俄罗斯克拉斯诺亚尔斯克地区南部）的淡水湖中，在Shushenskii Bor国家公园的一个保护区内发现了活的Lychnothamnus barbatus植物。这些遗址是西伯利亚和北亚的第一批遗址。这些地点与已知的中亚和东亚现存记录相去甚远，这证实了现存栖息地的独特性和脆弱性。

A living fossil charophyte Lychnothamnus barbatus newly found in southern Siberia (North Asia)

Lychnothamnus barbatus (Charophyceae, Characeae), one of the rarest relict macroscopic charophyte species in the world, has a distinct disjunctive range, having been known from fossil remains in northern Asia for a long period. Living plants of Lychnothamnus barbatus were found in freshwater lakes in southern Siberia in the Minusinsk forest-steppe (south of Krasnoyarsk Territory, Russia), within a conservation area in the Shushenskii Bor National Park. These sites are the first ones in Siberia and North Asia. The localities are situated far from known extant records from Central and Eastern Asia, which confirms the uniqueness and vulnerability of the extant habitats.

期刊介绍： Aquatic Botany offers a platform for papers relevant to a broad international readership on fundamental and applied aspects of marine and freshwater macroscopic plants in a context of ecology or environmental biology. This includes molecular, biochemical and physiological aspects of macroscopic aquatic plants as well as the classification, structure, function, dynamics and ecological interactions in plant-dominated aquatic communities and ecosystems. It is an outlet for papers dealing with research on the consequences of disturbance and stressors (e.g. environmental fluctuations and climate change, pollution, grazing and pathogens), use and management of aquatic plants (plant production and decomposition, commercial harvest, plant control) and the conservation of aquatic plant communities (breeding, transplantation and restoration). Specialized publications on certain rare taxa or papers on aquatic macroscopic plants from under-represented regions in the world can also find their place, subject to editor evaluation. Studies on fungi or microalgae will remain outside the scope of Aquatic Botany.
