| 1 | A Preliminary Study of Crassulacean Acid Metabolism (CAM) in the Endangered Aquatic Quillwort Isoetes sinensis Palmer in China显示文摘Isoetes sinensis Palmer (Isoetaceae) is an aquatic or amphibious plant that is critically endangered in China. Previous studies have revealed the crassulacean acid metabolism (CAM)-like photosynthetic pathway occurs com-monly in submerged leaves in genus Isoetes. Water chemistry parameters and the titratable acidity content of the plant extract were measured from samples obtained in the early morning (7:00) and late afternoon (15:00) from two I.sinensis populations in China. One population occurs in the eulittoral zone of a freshwater tidal river at low elevation (134 m) and another occurs in a densely vegetated, high elevation (1 100 m) alpine shallow pool. Significant differences in pH and titratable acidity of the plant extract were detected between the morning and afternoon samples. These changes are associated with diurnalchanges in water chemistry. Our results provide the first evidence for the exist-ence of the CAM pathwa in the East Asian endemic Isoetes sinensis Palmer.The magnitude of fluctuations in the titratable acidity of the plant extract mayb e correlated with the severe carbon limitation imposed on the plants by its aquatic habitat. | Pang Xin-an, Wang Qing-feng, Gituru W.

| 4 | Traditional knowledge, use and conservation of plants by the communities of Tharaka-Nithi County, Kenya显示文摘Rural communities in Kenya largely depend on plant resources for their livelihood.The utilization of these resources depends on the availability of plant resources and the level of knowledge of the residents.We conducted an ethnobotanical study in Tharaka-Nithi County in Kenya to determine the knowledge and utilization of various plant species by the local communities.The study was conducted in four major administrative regions from June 2018 to February 2019,involving interview schedules using semi-structured open-ended questionnaires and guided field collections with 48 informants.A total of 214 plant species distributed in 73 families and 169 genera with 616 Use Reports(URs)were documented.Fabaceae was the highest family cited by the informants(31 species)followed by Lamiaceae and Euphorbiaceae(each with 11 species).Trees(49%)and shrubs(32%)were the top life forms of the plants frequently utilized by the local residents.The general plant uses reported were medicinal,food,fodder,construction,fuel,pesticidal,religious,live fencing,and making crafts.Zanthoxylum gilletii,Prunus africana,and Solanum incanum were found to be highly valued by the local communities.Plant utilization as food and medicinal uses against snake-bite related problems had the highest Informant Consensus Factor(ICF).Only 29(13.6%)of the species reported had their status assessed by the International Union for Conservation of Nature(IUCN).Conservation measures,alongside awareness creation in this region,are highly recommended for the species endemic to the region,highly depended on by the community,and those threatened according to IUCN standards. | Vivian Kathambi Fredrick Munyao Mutie Peninah Cheptoo Rono Neng Wei Jacinta Ndunge Munyao Peris Kamau Robert Wahiti Gituru Guang-Wan Hu Qing-Feng Wang | 2020 | Plant Diversity2020，42，6： | 2 |
| 5 | Reproductive Biology and Prospects for Conservation of Caldesia parnassifolia (Alismataceae)——A Threatened Monocot in China显示文摘Caldesia parnassifolia (Bassi ex Linn.) Parl. in China has declined in number in r ecent years and is increasingly faced with the risk of extirpation arising from anthropogenic changes associated with rapid urbanization and expansion of both agriculture and infrastructure. To aid in provision of the data needed for effective conservation of the species, studies on the habitat, pollination ecology, and breeding system of C. parnassifolia were carried out on natural populations occurring in Southeastern China. Flowering in the study populations extended for more than eighty days beginning in early summer. Floral anthesis occurred in the morning hours and proceeded rapidly, lasting about 45 min. Flowers lasted ca. 8 h. Caldesia parnassifolia is self\|compatible; however autogamy resulted in lower seed set than geitonogamy and xenogamy as well as free pollination. The data on pollen/ ovule (P∶O) ratio is consistent with a partially selfing and outcrossing mating system. Interpopulational crosses yielded similar seed set to within\|population crosses. Agamospermy did not occur in the study populations. Propagation is achieved through seeds as well as through turions which commonly occur in the inflorescences. Flies (Insecta; Diptera) were the most frequent visitors to the flowers of C. parnassifolia; however bees (Insecta; Hymenoptera) composed a larger proportion of effective pollinators. The Syrphidae species Sphaerophoria indiana (Bigot) presents evidence of oligolectic foraging behavior. Recommendations are made on the immediate steps necessary for conservation of Caldesia species in China. | Gituru Wahiti Robe rt, Wang Qing\|feng , Wang Yong, Guo You\|hao Colleg e of Life Sciences, Wuhan University, Wuhan 430072, Hubei, China | 2003 | Wuhan University Journal of Natural Sciences2003，8，01A： | 2 |
| 6 | Spatial Distribution Pattern of Populations of Isoetes sinensis Palmer, an Endangered Quillwort in China显示文摘The distribution pattern of Isoetes sinensis populations was investigated in relation to its biological characteristics such as age structure and regeneration mode, and the microenvironment. Contagious distribution pattern was found in populations of all sizes. Under the same climatic and site conditions, the heterogeneity of microenvironment resulting from the different depths of water and soil erosion significantly affected the type and scale of distribution patterns of Isoetes sinensis populations. Even at the same site, the center and the edges of the water body had different effects on the distribution pattern of the plants. As one of the co-dominants, the distribution of Isoetes sinensis in communities was affected by other dominant species, especially by the evergreen grass species. Water is the major factor determining the distribution pattern of Isoetes sinensis in various communities. The pattern of contagious distribution was observed in different size of populations of I. sinensis, however the Lloyd indices obtained for the populations of various sizes differed significantly. | WANG Jingyuan Robert Wahiti Gituru CHEN Jinming WANG Oingfeng | 2006 | Wuhan University Journal of Natural Sciences2006，11，3： | 2 |
