Despite the lake being definitively drained in 1851, there is still today a fairly diverse aquatic flora in the remaining marshes and seasonal ponds. In this work, we present the catalogue of the flora of the aquatic plants in this Mediterranean wetland, compiled from field trips and from consultation of various herbaria and botanical works. Thus, according to our data, in the last 300 years, 37 aquatic plants have populated the lake, 12 of which are currently thought to have become locally extinct (although the presence of three of them is in doubt). The plants that have disappeared include Trapa natans, Marsilea quadrifolia, Najas minor and Rorippa amphibia . In addition, using the catalogue of flora, and following the criteria proposed by researchers of the Real Jardin Botanico de Madrid, we have carried out a botanical evaluation of Estany de Sils as a wetland area (I H index). Its botanical value has been found to be very high (an I H of 7.0 in 1850 compared to an I H of 6.9 in 2014) and the lake can still be considered a wetland of European importance nowadays. It must be noted, that the 30.6% and the 19.4% of the vascular aquatic plants existing in Catalan Countries and Spain, respectively, have been observed in the study area.","PeriodicalId":38447,"journal":{"name":"Collectanea Botanica","volume":"35 1","pages":"002"},"PeriodicalIF":0.0,"publicationDate":"2016-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70862240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Poyang Lake, located in the middle reaches of Yangtze River (central China), constitutes the largest freshwater lake of the country. It harbours high biodiversity and provides important habitat for local wildlife. A dam that will maintain the water capacity in Poyang Lake is currently being planned. However, the local biodiversity and the likely effects of this dam on the biodiversity (especially on the endemic and rare plants) have not been thoroughly examined. Therefore, in order to assess the richness of plant species and plant communities in Poyang Lake, we conducted a detailed field investigation combined with a literature review. A total of 124 families, 339 genera, and 512 species (including sub-species, varieties and forms) as well as eight dominant plant communities were identified, confirming the lake’s wetland as a regional hotspot of plant diversity. It is imperative to carry out further research on the impact of damming on the vegetation, particularly research focusing on protecting local biodiversity, maintaining the lake’s ecosystem services, controlling the spread of invasive species, and restoring degraded ecosystems.","PeriodicalId":38447,"journal":{"name":"Collectanea Botanica","volume":"34 1","pages":"004"},"PeriodicalIF":0.0,"publicationDate":"2015-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70861513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It spans the whole upper reaches of Zhujiang River, the largest river in Southern China. In this paper, I aimed to explore the roles of the river in the spread and diversification of tropical plants in this area, using the Asia-endemic genus Hiptage Gaertn. (Malpighiaceae) as an example. Two diversity and endemism centres of Hiptage are recognized: Indo-China Peninsula and upper reaches of Zhujiang River (UZJ). The area-adjusted endemism index further indicates UZJ as the most important distribution region of endemic species since UZJ has a very small area (~210,000 km 2 ) but six out of the total seven species are narrow endemics. UZJ is located at the northern edge of distribution ranges of Hiptage , which resulted mainly from the north-west–south-east river systems of UZJ promoting northward spreads of this tropical genus. The highly-fragmented limestone landscapes in this region may promote habitat isolation and tends to be the main driving factor for origins of these endemic species. Hiptage is also distinctive for its highly-specialized pollination system, mirror-image flowers, which probably facilitates species diversification via floral and pollination isolation. Other studies also found UZJ as a major diversification centre of the tropical plant families Gesneriaceae and Begoniaceae. Thereafter, it is concluded that UZJ is an “evolutionary front” of tropical plants in China, which contributes significantly to the origin and maintenance of the unique biodiversity in the area.","PeriodicalId":38447,"journal":{"name":"Collectanea Botanica","volume":"34 1","pages":"003"},"PeriodicalIF":0.0,"publicationDate":"2015-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70861849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leaf mines are distinct marks on leaves and can provide much information on insect-plant relationships. Most leaf miners are monophagous or oligophagous. Therefore ecologists and paleontologists use them to study interactions and coevolution among plants, insects and natural enemies. There are many different types of leaf-mining patterns on plant leaves, which may have different impacts on host plants. Compared with ectophagous herbivores, leaf-mining insects should have unique influences on host plant characteristics, such as leaf morphology, leaf chemistry, plant physiology, plant growth and production. Obvious impacts include leaf asymmetry, callus formation, photosynthesis, and green islands. Types and degrees of such influences are varied for different leaf miner species or different host plant species. In turn, the change of plant features may have positive or negative impacts on oviposition and feeding of leaf-mining insects. Studies on plant responses to leaf-mining and the defensive mechanisms of plants are helpful in understanding the coevolution between leaf miners and their food plants.","PeriodicalId":38447,"journal":{"name":"Collectanea Botanica","volume":"34 1","pages":"005"},"PeriodicalIF":0.0,"publicationDate":"2015-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70861560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the largest tropical island of China, Hainan has five tropical forest vegetation types, namely deciduous monsoon forest, lowland rainforest, montane rainforest, montane evergreen forest, and montane cloud forest. There are 317 orchid species in the island, including 33 endemic, 158 epiphytic, 148 terrestrial, and 11 saprophytic species. Most orchids, which are mainly located in central and southern parts of the island, are generally distributed in damp tropical forests in mountains at an altitude of 500–1500 m. Highest level of endemism is also centred in these areas. Orchids are especially threatened by habitat fragmentation because they grow in small populations, and fragmentation may block gene flow and result in lower genetic diversity. In addition, due to their ornamental and medicinal value, many orchids are over-collected. Therefore, orchid conservation in Hainan Island is very urgent. The aim of this article is to determine the distribution pattern of orchids and expound research and conservation status in Hainan Island, and to propose conservation strategies for the future.","PeriodicalId":38447,"journal":{"name":"Collectanea Botanica","volume":"34 1","pages":"007"},"PeriodicalIF":0.0,"publicationDate":"2015-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70861711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
