摘要
摘要基于文献、形态学和分子生物学研究(SSU rDNA),对20世纪初发现的地中海特有种——毛茛(Chaetomorpha stricta Schiffner)进行了恢复种级的研究。C. stricta先前被认为是C. linum (O.F. m ller) k tzing的后异型同质物,其分子数据与后者明显不同,其小的,浅绿色的,自由生活的细丝缠绕在密集的团块中,细胞长0.5至1.6倍(很少2),细胞壁片状,宽达75-90 μm厚。2011年5月,在Cavallino山谷(威尼斯泻湖北部盆地)一个封闭渔池的贫营养清澈水域中重新发现了Chaetomorpha stricta。本文综述了地中海Chaetomorpha分类群的研究进展,并提出了地中海Chaetomorpha分类群的分类关键。
Rediscovery of a Forgotten Mediterranean Chaetomorpha Species in the Venice Lagoon (North Adriatic Sea): Chaetomorpha stricta Schiffner (Cladophorales, Chlorophyta)
Abstract
On the basis of bibliographical, morphological and molecular studies (SSU rDNA), the reinstatement of species rank for Chaetomorpha stricta Schiffner, a poorly known Mediterranean endemic species described in the early 20th century, is proposed. Previously reduced to a posterior heterotypic synonym of C. linum (O.F. Müller) Kützing, C. stricta clearly differs from the latter by its small, light green, free-living filaments entangled in dense masses, the cells 0.5 to 1.6 (rarely 2) times as long as broad, with cell walls lamellate and broad up to 75–90 μm thick, and by molecular data. Chaetomorpha stricta was rediscovered, in May 2011, in oligotrophic clear waters of a closed fishing pond in the Valle Cavallino (northern basin of the Venice Lagoon). A critical review of Chaetomorpha taxa reported in the Mediterranean Sea and a taxonomic key to the Mediterranean taxa currently accepted are presented.
