	abstract = {The genetic diversity of 56 individuals of Iso{\"e}tes hypsophila Hand.-Mazz. from China was investigated by ISSR. Twelve primers were screened from 65 primers, and a total of 119 DNA fragments were scored, of these, 82\% were polymorphic bands, which indicated that high levels of genetic variation existed in the natural populations. Genetic diversity varied greatly among populations with the percentage of polymorphic band (PPB) values ranging from 8 to 35\%. An analysis of molecular variance (AMOVA) was used to apportion the variation between regions, among populations within regions, and within populations. Results indicated that most of the variance (85\%) occurred between Yunnan and Sichuan. The variances among populations within regions and within populations, however, were only 5 and 10\%, respectively. In the among-population analysis, the larger part of genetic variation (77\%) resided among populations, and less (23\%) presented differences within populations. UPGMA cluster analysis showed that there was no distinct genetic differentiation between populations from Sichuan province. A number of causes including limited gene flow, genetic drift and inbreeding might have led to these observed genetic profiles of I. hypsophila. {\textcopyright} 2005 Elsevier B.V.

	abstract = {Isoetes sinensis Palmer is an East Asia endemic fern that faces impending extirpation from the expansive area of Mainland China. Presently, only two natural populations are known to exist in this vast region. Both populations have decreased by about 50\% within the last 4 years. This reduction is most probably related to the decline in the size of the wetlands since reproductive activity, spore production, and recruitment were noticeably lower at the microsites occurring in smaller ponds. The decline in population size seems to be associated with succession from marsh to dry land at the habitats of both populations. The study revealed that individuals in both populations produced copious numbers of spores suggesting adequate fecundity, furthermore high levels of spore germination were obtained in laboratory experiments. However, inefficient spore dispersal appears to have contributed to the limited spread of the species. The sex ratio in both populations was male-biased. Several factors are identified here as posing a threat to Isoetes sinensis populations in China, chiefly the loss of habitat due to infrastructure construction and competition with adventive weed species for establishment on available sites. Disturbance by introduced mammals during browsing and trampling by livestock farm workers, as well as tourists, further contribute to the diminishing numbers of Isoetes sinensis at the study sites. {\textcopyright} 2005 Taylor \& Francis.},

	abstract = {Isoetes coreana Chung and Choi is on the list of critically endangered species in South Korea. Using randomly amplified polymorphic DNA (RAPD) markers, we investigated the genetic diversity within and between seven local populations of I. coreana. Ten RAPD primers produced a total of 94 bands, of which 59 (62.8\%) were polymorphic. A low level of genetic diversity was recognized within the populations of I. coreana: polymorphic loci (P), with values ranging from 3.4\% to 33.9\%, and a mean value of 15.5\% being observed. Analysis of molecular variance (AMOVA) showed that genetic diversity was greater among populations (81.6\%) than within populations (19.7\%) or among the three regions included in this study (Han River, Youngsan River, and Nakdong River). In addition, a high degree of genetic differentiation (θB = 0.742) was detected among the populations. These results indicate that genetic differentiation has occurred very rapidly. However, the rate of gene flow between populations was found to be as low as 0.059, irrespective of the genetic and geographical distances between the populations, which indicates that genetic drift must have played an important role in forming the present populations of I. coreana. Because a reduction of genetic diversity as a result of genetic drift is undesirable, increasing the gene flow between populations of Korean quillwort I. coreana should be considered as a conservation strategy. {\textcopyright} 2008 Elsevier B.V.

	abstract = {Isoetes hypsophila Hand.-Mazz. (Isoetaceae) is an endangered alpine quillwort endemic to the Qinghai-Tibetan Plateau (QTP). A total of 247 individuals of I. hypsophila from 11 populations were analyzed using ten pairs simple sequence repeats (SSR) markers. Seventy-seven alleles were recorded, with an average of 7.7 alleles per locus (ranging from 3 to 12) and the expected heterozygosity (HE) ranged from 0.392 to 0.536 (average 0.471). Clear population structure among I. hypsophila populations was found and the proportion of genetic differentiation among populations accounted for about 20\% of total genetic diversity (FST = 0.178; probability of allelic co-ancestory Fcoal = 0.238). This genetic structure was probably due to limited gene flow hindered by complex terrains, bottlenecks resulting from water fluctuation in habitats, and repeated population retreat and recolonization during the ice ages. In conservation, four management units corresponding to four geographic regions were suggested, and the populations from different management units with higher genetic variation should be the priority targets of both in situ and ex situ conservation. {\textcopyright} 2012 Elsevier Ltd.},

	abstract = {Isoetes taiwanensis DeVol, discovered in 1971, is a critically endangered aquatic plant endemic to Taiwan. The only natural habitat of I. taiwanensis is the Menghuan Pond wetland in northern Taiwan. With competition of some aquatic plants and terrestrial plants, I. taiwanensis was close to extinction in 2006. The bottom of the Menghuan Pond wetland was compacted and fractures were filled along the shore to improve the average water depth in 2008. The I. taiwanensis population was restored, but factors crucial to its survival remain unclear. To analyze the factors, we monitored 24 plots in the Menghuan Pond wetland monthly from January to December 2010 to record the coverage rates of potential competitive plant species and hydrology data. The wetland was found to be an ideal environment for growth of I. taiwanensis with annual mean water depth 50 cm. The species did not grow in plots with annual mean water depth lower than 30 cm. The species had an advantage over other species in plots with annual mean water depth 46. 8-185. 6 cm. The coverage rate of I. taiwanensis was positively associated with annual mean water depth. With the deepest annual mean water level, >60 cm, more than 90 \% of the area was covered. Fluctuation of the water level may reduce the competition among I. taiwanensis and other species, particularly Eleocharis congesta, E. dulcis, and Schoenoplectus mucronatus. These data may help in designing a protocol for sustained conservation of I. taiwanensis in Yangmingshan National Park. {\textcopyright} 2012 Springer-Verlag.},
