	abstract = {Isoetes sinensis is a critically endangered aquatic quillwort, occurring in two fragmented sites of China (Xiuning county of Anhui; Jiande county of Zhejiang). During a five-year period (2004-2009), the areas and sizes of the two populations diminished dramatically due to intensive human activities. Genetic structure of the species was investigated using simple sequence repeat makers (SSRs). For seven nuclear microsatellites, high levels of genetic diversity were found within populations (H E=0.324-0.447). Strong genetic differentiation was detected between populations (G ST=0.376), while weak genetic differentiation was found within populations (G ST=0.026-0.080). Notably, in contrast to the source-sink model suggested by previous study (Chen et al., 2009), the migration pattern of I. sinensis along the Xin{\textquoteright}an River is best explained by the linear symmetrical non-adjacent flow model (LSNF), which indicates that intensive human activities of recent years have greatly affected the gene exchange pattern among I. sinensis subpopulations. {\textcopyright} 2011 Elsevier B.V.},

	abstract = {The genus Isoetes is represented in Bulgaria by one species I. lacustris L. (lake quillwort). It inhabits the littoral areas of some lakes in the Pirin Mountain range. Fossil records of Isoetes in Bulgaria are very scarce. A new palynological study was conducted on sediments collected from Kupena Mire in the Western Rhodope Mountains. The results indicated that lake quillwort was abundant 30 000 years ago and its growth was associated with the presence of shallow lake basins. The species disappeared from the composition of the local flora as the sedimentation regime changed from lacustrine to marsh after the warming of the climate at the onset of the Holocene. This study confirmed the existence of refugial areas during the last glaciation in the mountains of Southeastern Europe, where a number of glacial relics had survived.},
