Taxonomy and Biogeography of the Genus Colura

Taxonomy and Biogeography of the Genus Colura Jiroat Sanngrattanaprasert   English: Taxonomy and biogeography of the genus Colura (Dumort.) Dumort. (Lejeuneaceae, Marchantiophyta) in Tropical East Asia Introduction Colura (Dumort.) Dumort. was coined by Dumortier (1835) in Recueil dObservations sur les Jungermanniacà ©es and C. calyptrifolia (Hook.) Dumort. was used as a holotype. This genus belongs to Lejeuneaceae, which is the largest family of the liverworts (Gradstein, 2013). The Colura was found in all Floristic regions except USA (Fig. 1), comprising 76 taxa, of which 39 endemic taxa are also reported. Tropical East Asia is the region where Pà ³cs (1996) had reported the highest number, both total and endemic, of taxa in the area. Species of Colura are typically recognized by their leaf morphology; the presence of lobules forming an apical sac with an aperture mechanism consisting of a valve and a hinge. This sac varies greatly in sizes and shapes, and may function a water retention and in some species as zoophagy (Barthlott et al., 2000). Most species of Colura can be considered being epiphyllous, but many of them can occur likewise on small twigs. Colura species grow in well-illuminated sites from the lowlands to about 4,000 m above sea level. A few species (e.g. C. ornithocephala) of this genus, especially those from high montane habitats, were never observed on leaves, but seem to inhabit exclusively on thin twigs or sometimes on the bark of thicker tree trunks. (Pà ³cs, 1996; Heinrichs et al., 2012). Two critically endangered Colura species (C. heimii Jovet-Ast and C. obesa Jovet-Ast) found in Rà ©union Island, where is the largest island of the Mascarene Archipelago in the western Indian Ocean, were listed in IUCN Red List (Ah-Peng et al., 2012). In addition, Gradstein, Raeymaekers and Churchill (2000) reported common taxa such C. clavigera be as an indicator of undisturbed rainforest in Tropical America (including Mexico). Tropical East Asia region consists Myanmar, Laos, Cambodia, Vietnam, Thailand, Malaysia, Singapore, Brunei, the Philippines, Western Indonesia, Southern China (north to 30 °N), plus the Ryukyu Islands of Japan and the Andaman as well as Nicobar Islands of India.

The description, ecological data and distribution patterns of all taxa of the genus Colura on Tropical East Asia will be provided. 2. The synoptic account of Colura species will be enumerated. Literature review Checklists in Asia Herzog (1921) investigated liverworts in Moluccan Island, Indomalaya. Two Colura species was found, viz. C. brevistyla Herz. and C. javanica Steph., the first one was the new to science. Mizutani (1961) revision studied of Lejeuneaceae in Japan, Colura tenuicornis and C. meijeri were found. Description, key to species and illustration were added. Kitagawa (1969) collected hepatic plants from Penang, Malaysia. Two species of Colura was reported, viz. C. acutifolia Jovet-Ast and C. corynephora (Nees) Trev. Pà ³cs and Ninh (2005) collected the hepatic plants from Vu Quang Nature Reserve in central Vietnam and found Colura brevistyla Herz. as be as a new record to Indochina, furthermore, C. corynephora (Nees) Trev. as well was listed in this record. Zhu (2006) reported a checklist of liverwort, hornwort and takakiophytes from China, of which seven taxa of Colura (C. acroloba, C. ari, C. conica, C. corynephora, C. inuii, C. karstenii and C. tenuicornis) were listed. Lai, Zhu and Chantanaorrapint (2008) reported an updated checklist of liverwort and hornwort in Thailand. Among the account there are 6 species of Colura, viz. C. acroloba (Mont. ex Steph.) Ast, C. conica (Sande Lac.) K.I. Goebel, C. corynephora (Nees et al.) Trevis., C. siamensis Jovet-Ast, C. superba and C. tixieri. Sà ¶derstrà ¶m, Gradstein and Hagborg (2010) reported 15 taxa of Colura in Java, including 12 taxa that be a good species or accepted except 3 taxa (C. denticulata Jovet-Ast, C. imperfecta Steph. and C. junghuhniana (Steph.) Steph.) that be probably a good species. Chuah-Petiot (2011) listed the account and phytogeographical data of liverworts and hornworts of all states in Malaysia. Seventeen species of Colura were found and enumerated. Wang, Lai and Zhu (2011) updated checklist and floristic accounts of liverworts as well as hornworts in Taiwan. The present list contains 512 species of liverwort belonging to 116 genera in 52 families, including three taxa of Colura (viz. C. acroloba (Mont. ex Steph.) Jovet-Ast, C. inuii Horik. and C. tenuicornis (Evans) Steph.) Dey Singh (2012) investigated epiphyllous liverworts of Eastern Himalaya, which Colura tenuicornis was reported in this study. Pà ³cs (2012) have small collected epiphyllous liverworts from Laos, which Colura tenuicornis (Evans) Steph. was reported with this list. Pà ³cs and Ninh (2012) reported epiphyllous liverworts from Cà ¡t Tià ªn National Park of Southern Vietnam. They found 21 species including two species of Colura, viz. C. conica (Sande Lac.) Goebel and C. ornata Goebel, the latter was a new to Vietnam. Pà ³cs (2013) investigated the genus Colura in New Guinea and in neighboring areas. This paper based on the collection made in 1981 by a joint expedition of the University of Helsinki and the Humboldt State University of Arcata and on other collections, there are 25 species present. The phytogeographical evaluation of all species was provided. The description and illustration of four new to science species (C. koponenii, C. medusa, C. mizu-tanii and C. norrisii) were equipped. Furthermore, he as well treated C. simplicior Jovet-Ast (1983) to be a synonym of C. denticulata. Jovet-Ast (1954). Pà ³cs, Luong and Ho (2013) examined epiphyllous liverworts in Bidoup-Nà ºi Bà   National Park, Vietnam. Among the 125 samples containing 43 species belong to Lejeunea-ceae, both Colura acroloba (Mont. ex Steph.) and C. superba (Mont.) were found. These two species distribute particularly in Giang Ly station, where the altitude is 1481-1500 m a.s.l. Checklists in Oceania Thiers (1987) reported ten taxa of Colura in Australia, viz. C. acroloba (Mont.) Steph., C. ari Steph., C. australiensis Jovest-Ast, C. bisvoluta Herz. et Jovet-Ast, C. conica (Sande Lac.) Goeb., C. crispiloba Jovest-Ast, C. pulcherrima var. bartlettii Jovet-Ast, C. queenslandica B. Thiers, C. saccophylla Hodgs. et Herz. and C. simplicior Jovet-Ast. Among them, three species (C. acroloba, C. ari and C. conica) were first reportedly seen according to this investi-gation, especially C. queenslandica sp. nov. was new to science. A key to all ten taxa was provided. Moreover she additionally validate Colura sect. Lingua Jovet-Ast ex Thiers. Pà ³cs and Streimann (2006) collected five taxa of Colura, viz. C. apiculata (Schiffn.) Steph., C. leratii (Steph.) Steph., C. crispiloba Jovet-Ast, C. ornata Goebel and C. queenslan-dica Thiers in Queensland, New South Wales, and Victoria states as well as the Austral Capital Territory. Pà ³cs and Eggers (2007) investigated ten species of Colura from the Fiji archipelago. Three new to Fiji (C. crispiloba Jovet-Ast, C. cristata Jovet-Ast and C. queenslandica Thiers) as well as C. vitiensis Pà ³cs et Eggers which was a new to science were added in this paper. The photograph and illustration of some species and together with dichotomous key to all species were provided. Pà ³cs et al. (2011) reported Colura brevistyla Herz. and C. tenuicornis (Evans) Staph. be as new record taxa for the Fiji Islands. C. acroloba also was listed in extended distribution records from new islands within Fiji. Sà ¶derstrà ¶m et al. (2011) accounted the checklist of liverworts and hornworts of Fiji, including the islands Viti Levu, Vanua Levu, Taveuni, Kadavu, Ovalau and surrounding smaller islands. The checklist of 14 species which belong to genus Colura were provided; furthermore the synonymous data were enumerated. Checklists in Amarica Engel (1978) had taxonomically and phytogeographically studied of Hepaticae and Anthocerotae in Brunswick Peninsula, Chile. Reportedly, three species of Colura were found, viz. C. calyptrifolia (Hook.) Dumort., C. naumannii (Schiffn.) Steph. and C. patagonica Jovet-Ast. Dauphin et al. (1998) reported Colura verdoornii Herz. et Jovet-Ast as new to Costa Rica, Tropical America. This species was previously known from Malaysia and Borneo, but it probably has a pantropical distribution, but not been reported from Africa. Checklists in Africa Jones and Harrington (1983) reported phytogeographical data of hepatic plant in Sierra Leone and Ghana, of those taxa, three species of Colura (C. digitaris (Mitten) Steph., C. dusenii (Steph.) Steph. and C. tenuicornis (Evans) Steph.) were included. Pà ³cs (1993) found new Colura from Comoro Archipelago and coin it as C. hattoriana Pà ³cs in this paper, including description, type specimens, illustration and note. Fischer (1999) reported five species of Colura from Aberdare mountain, Kenya, viz. C. berghenii Jovet-Ast, C. calyptri-folia (Hook.) Dumort., C. hedbergiana Pà ³cs, C. tenuicornis (Evans) Steph. and C. zoophaga Fischer, the latter species was a new to science. Wigginton (2001) investigated about habitat and location for 64 taxa that belong to Leajeuneaceae in Mulanje Mountain, Malawi. There are four Colura spp. which was reported in this investigation, viz. C. calyptrifolia , C. digitalis, C. tenuicornis and C. usambarica. Chuah-Petiot and Pà ³cs (2003) treated Colura zoophaga Fischer (1999) to be a synonym of C. kilimanjarica Pà ³cs et Jovet-Ast which they was found in same place, Aber-dare Mountain, Kenya and in addition they grew together on the twig of Cliffortia nitidula (Chuah-Petiot and Pà ³cs, 2003; Fischer, 1999). Mà ¼ller and Pà ³cs (2007) investigated epiphyllous bryophyte of Bioko Island (Equatorial Guinea), biogeography of three species of Colura (viz. C. calderae Pà ³cs, C. digitalis (Mitt.) Steph. and C. hattoriana Pà ³cs, which the first one was a new to science) were provided.

Malaysia Chinese Culture

Malaysia's cultural mosaic is marked by many different cultures, but several in particular have had especially lasting influence on the country. Chief among these is the ancient Malay culture, and the cultures of Malaysia's two most prominent trading partners throughout history–the Chinese, and the Indians. These three groups are joined by a dizzying array of indigenous tribes, many of which live in the forests and coastal areas of Borneo. Although each of these cultures has vigorously maintained its traditions and community structures, they have also blended together to create contemporary Malaysia's uniquely diverse heritage. Populated by the three (3) major races found in Asia, Malaysia culture is a melange of Indian, Malay and Chinese influence The Spring Festival is the most important festival for the Chinese people and is when all family members get together, just like Christmas in the West. All people living away from home go back, becoming the busiest time for transportation systems of about half a month from the Spring Festival. Airports, railway stations and long-distance bus stations are crowded with home returnees. The Chinese character â€Å"fu† (meaning blessing or happiness) is a must. The character put on paper can be pasted normally or upside down, for in Chinese the â€Å"reversed fu† is homophonic with â€Å"fu comes†, both being pronounced as â€Å"fudaole. † What's more, two big red lanterns can be raised on both sides of the front door. Red paper-cuttings can be seen on window glass and brightly colored New Year paintings with auspicious meanings may be put on the wall. Waking up on New Year, everybody dresses up. First they extend greetings to their parents. Then each child will get money as a New Year gift, wrapped up in red paper. People in northern China will eat jiaozi, or dumplings, for breakfast, as they think â€Å"jiaozi† in sound means â€Å"bidding farewell to the old and ushering in the new†. Also, the shape of the dumpling is like gold ingot from ancient China. So people eat them and wish for money and treasure. Burning fireworks was once the most typical custom on the Spring Festival. People thought the spluttering sound could help drive away evil spirits. However, such an activity was completely or partially forbidden in big cities once the government took security, noise and pollution factors into consideration. As a replacement, some buy tapes with firecracker sounds to listen to, some break little balloons to get the sound too, while others buy firecracker handicrafts to hang in the living room. People in different places follow various customs, but all show their love and longing for a better life. Today people will enjoy the full moon and eat moon cakes on that day. The moon looks extremely round, big and bright on the 15th day of each lunar month. People selected the August 15 to celebrate because it is a season when crops and fruits are all ripe and weather pleasant. On the Mid-Autumn Festival, all family members or friends meet outside, putting food on tables and looking up at the sky while talking about life. How splendid a moment it is! | There are many legends about the evolution of the festival, the most popular of which is in commemoration of Qu Yuan. People will dragon boat racing, eating zongzi and drinking realgar wine on that day. On Dragon Boat Festival, parents also need to dress their children up with a perfume pouch. They first sew little bags with colorful silk cloth, then fill the bags with perfumes or herbal medicines, and finally string them with silk threads. The perfume pouch will be hung around the neck or tied to the front of a garment as an ornament. They are said to be able to ward off evil. | The Qingming Festival sees a combination of sadness and happiness. This is the most important day of sacrifice. Both the Han and minority ethnic groups at this time offer sacrifices to their ancestors and sweep the tombs of the deceased. Also, they will not cook on this day and only cold food is served. On each Qingming Festival, all cemeteries are crowded with people who came to sweep tombs and offer sacrifices. Traffic on the way to the cemeteries becomes extremely jammed. The customs have been greatly simplified today. After slightly sweeping the tombs, people offer food, flowers and favorites of the dead, then burn incense and paper money and bow before the memorial tablet.

Stem Cell Research Stem Cells - 1999 Words

Many of us have all heard the saying that a â€Å"lizard can lose its tail,† and bizarrely enough it will grow back. This was always considered impossible for humans, an idea belonging in the realm of science fiction, but now the regeneration of tissue is an extremely realistic possibility. Despite some opinions, this process does not happen naturally, or take place as cinematically as one might imagine. Over the past decade, there have been major advances in regenerative medicine, commonly known as stem cell research. Stem cells are undifferentiated cells within the body that have the capability to specialize into any tissue. They are most commonly found in cord blood, bone marrow, organ donations, placenta, and embryos . Stem cells are seen by some as a new miracle treatment, encouraging many countries to invest in their research. The transfer of information, often shared through scientific reports and research, puts this topic in a highly international spotlight. Many supporters believe that stem cells will be able to help solve once untreatable diseases or injuries such as spinal cord injuries, skin burns, Parkinson’s disease, and some blood disorders. However, the main argument is if stem cells should be used in finding therapeutic treatments. The use of embryonic stem cells is viewed by many as a moral inconsistency; it is opposed by religious organizations and individuals believing that this research should be abandoned and existing, alternative methods be adapted.Show MoreRelatedStem Cell Research : Stem Cells1338 Words   |  6 Pages Stem Cells Stem cells are cells that are found throughout the human body.
