摘要
异色木贼。前Weber et Mohr(马齿科L. Rich)。是一种多年生常绿植物,根茎较长。它生长在北极苔原和山区栖息地。通常,E. variegatum被认为是立陶宛罕见或相当常见的植物物种。在过去的60年里,变异野鼠的数量增加了10倍以上。因此,对立陶宛的异叶大蠊分布格局、生境多样性和环境保护状况进行分析具有重要意义。利用立陶宛4个植物标本馆的马尾标本和个人研究资料,分析了马尾的分布和生境。分析结果表明,立陶宛60个行政区中有27个行政区发现了变异鼠。大约70%的斑羚栖息地是人为的,主要分布在废弃的砂石采石场。在立陶宛东南部和西部以及沿海地区确定了三个自然发生的变异仓鼠栖息地集中区。立陶宛典型的自然栖息地是潮湿的草甸、湖岸、沼泽、海岸沙丘和松林。在立陶宛的自然栖息地,E. variegatum是罕见或非常罕见的,而在人为栖息地则相当罕见或相当常见。在后一种生境中,异叶松经常形成灌丛。
Equisetum variegatum Schleich. ex Weber et Mohr in Lithuania: habitat diversity, distribution patterns and environmental status based on herbarium collection
Equisetum variegatum Schleich. ex Weber et Mohr (Equisetaceae L. Rich. ex DC.) is a perennial evergreen plant with a long rhizome. It grows in Arctic tundra and mountain habitats. Usually E. variegatum is assigned to rare or fairly frequent plant species in Lithuania. During the last six decades the number of E. variegatum localities increased more than tenfold. Therefore it is important to perform an analysis of E. variegatum distribution patterns, diversity of localities, and environment protection status in Lithuania.
In order to analyse E. variegatum distribution and habitats, herbarium specimens of the horsetail in four Lithuanian herbaria as well as the data obtained during personal research were used. The analysis showed that E. variegatum is found in 27 of 60 administrative districts of Lithuania. Approximately 70% of E. variegatum habitats are anthropogenic, found mainly in the abandoned sand or gravel quarries.
Three naturally occurring E. variegatum habitat concentration zones were determined in south-eastern and western Lithuania as well as on the coast. Typical naturally occurring E. variegatum habitats in Lithuania are wet meadows, lake shores, fen, coastal dunes, and pine forests. E. variegatum is rare or very rare in natural habitats and fairly rare or fairly common in anthropogenic habitats in Lithuania. In the latter habitats E. variegatum frequently forms thicket.
