The NCEF was subjected to detect the presence of various phytoconstituents. In acute oral toxicity study, graded doses of NCEF was administered in mice and were observed up to 14 days. In sub-chronic oral toxicity study, NCEF was admin- istered to Wistar rats at doses of 50, 500 and 1000 mg/kg b.w. per day for 90 days and after that, observed up to 28 days. NCEF showed the presence of alkaloids, steroids, phenolics and glycosides. In acute toxicity study, there was no mortality and no behavioural signs of toxicity at the highest dose level (6400 mg/kg b.w.).

  • Chiang Rai Travel Guide Book
    www.thelostpassport.com The Ultimate Chiang Rai Travel Guide www.thelostpassport.com Why You Need to Visit Chiang Rai Most people say there aren't many things to do in Chiang Rai. They're wrong, and I'm going to show you why. All other Chiang Rai travel guides cover attractions near the town such as; White Temple, Black House, the Clock Tower. Sure, these are interesting, and you should visit them, but there is so much more to be discovered. The reality is that most travellers don't go beyond the town, and really miss out loads of amazing things to do in Chiang Rai. Chiang Rai has a very diverse culture. There are the people of Northern Thailand which speak their own dialect of Thai called Lanna. Then there are the countless ethnic villagers such as Lahu, Karen, and Hmong which have lived in the mountains around the borders of Cambodia, Laos, China and Thailand for centuries. They maintain age old traditions not seen elsewhere in Thailand. The nature in Chiang Rai is stunning. While living there I discovered beautiful waterfalls, amazing mountain hikes, relaxing hot springs, and even a beach! I explored by longtail boat down and upriver, motorbiked off-beat trails in the national park, and cruised about town in a Tuk-Tuk after one too many beers. Chiang Rai is no doubt an incredible place. Now I want to share my experience with you.

  • 4. the Plant Diversity of Singapore
    FLORA OF SINGAPORE (Vol. 1: 37–46, 2019) 4. THE PLANT DIVERSITY OF SINGAPORE K.M. Wong & S.K. Ganesan The position of Singapore on the Sunda continental shelf is a special one, with the principal island originally about 540 km2 in extent, together with some 60 smaller islands at the southern exit to the Malacca Strait and near the confluence of the South China Sea and Karimata Strait just west of Borneo. Geographically at the equatorial extremity of the Malay Peninsula, Singapore is separated from the Riau islands to its south (principally the Karimun Islands, Batam and Bintan) by the Singapore Strait which includes the deeply scoured 204-m ‘Singapore Deeps’, a likely subsidence basin resulting from tectonic movements (Bird et al., 2006). While this Strait may seem able to restrict the dispersal of some organisms with interglacial and post- Pleistocene high sea levels, it probably was not an effective dispersal barrier during episodes of lowest sea levels, such as during the Last Glacial Maximum (LGM) at 18 ka. Then, it must have been in the path of a key land bridge between mainland Southeast Asia farther north and likewise exposed links to Java and other areas to the south (Ho, 1960; Morley & Flenley, 1987; Heaney, 1991; Voris, 2000; Bird et al., 2005). By contrast, the Johor Strait that separates Singapore from south Peninsular Malaysia is just about 10 m deep and 600 m wide at its narrowest. The Sundaland region on the Sunda continental shelf has seen climate shifts since even before the Pleistocene, sometimes associated with tectonic events.

  • Tabebuia Roseo-Alba
    Tabebuia roseo-alba Tabebuia roseo-alba, known as white ipê, ipê-branco or lapacho blanco, is a Tabebuia roseo-alba tree native to Cerrado and Pantanal vegetation in Brazil, but also appears in Argentina (especially in the "Esteros del Ibera" wetlands) and more rarely in Paraguay. This plant is frequently used as an ornamental plant and honey plant in Brazil and Argentina.[2] On the other hand, its flowers seem to be less popular with many hummingbirds than those of other Tabebuia, being visited mostly by the occasional generalist species like the Gilded Sapphire (Hylocharis chrysura).[3] See also List of honey plants List of plants of Cerrado vegetation of Brazil List of plants of Pantanal vegetation of Brazil Scientific classification Kingdom: Plantae References Clade: Tracheophytes 1.

Polhemus Previous collections of aquatic Heteroptera from Cambodia have been limited, and the biota of the country has remained essentially undocumented until the past several years. Recent surveys of aquatic Heteroptera in the Cardamom Mountains and adjacent Kirirom and Bokor plateaus of southwestern Cambodia, coupled with previous literature records, demonstrate that 11 families, 35 genera, and 68 species of water bugs occur in this area. These collections include 13 genus records and 37 species records newly listed for the country of Cambodia. The following four new species are described based on these recent surveys: Amemboa cambodiana n. sp. (Gerridae); Microvelia penglyi n. sp., Microvelia setifera n. sp. and Microvelia bokor n. sp. (all Veliidae). Based on an updated checklist provided herein, the aquatic Heteroptera biota of Cambodia as currently known consists of 78 species, and has an endemism rate of 7.7%, although these numbers should be considered provisional pending further sampling.

The following six phytogeographic regions (at the rank of floristic province) are distinguished and outlined within eastern Indochina: Sikang-Yunnan Province, South Chinese Province, North Indochinese Province, Central Annamese Province, South Annamese Province and South Indochinese Province. Short descriptions of these floristic units are given along with analysis of their floristic relationships. Special floristic analysis and consideration are given to the Orchidaceae as the largest well-studied representative of the Indochinese flora. 1.

    BIODIVERSITY CONSERVATION ON THE TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and plants Report prepared by John Woinarski, Kym Brennan, Ian Cowie, Raelee Kerrigan and Craig Hempel. Darwin, August 2003 Cover photo: Tall forests dominated by Darwin stringybark Eucalyptus tetrodonta, Darwin woollybutt E. miniata and Melville Island Bloodwood Corymbia nesophila are the principal landscape element across the Tiwi islands (photo: Craig Hempel). i SUMMARY The Tiwi Islands comprise two of Australia’s largest offshore islands - Bathurst (with an area of 1693 km 2) and Melville (5788 km 2) Islands. These are Aboriginal lands lying about 20 km to the north of Darwin, Northern Territory. The islands are of generally low relief with relatively simple geological patterning. They have the highest rainfall in the Northern Territory (to about 2000 mm annual average rainfall in the far north-west of Melville and north of Bathurst). The human population of about 2000 people lives mainly in the three towns of Nguiu, Milakapati and Pirlangimpi. Tall forests dominated by Eucalyptus miniata, E. tetrodonta, and Corymbia nesophila cover about 75% of the island area. These include the best developed eucalypt forests in the Northern Territory. The Tiwi Islands also include nearly 1300 rainforest patches, with floristic composition in many of these patches distinct from that of the Northern Territory mainland. Although the total extent of rainforest on the Tiwi Islands is small (around 160 km 2 ), at an NT level this makes up an unusually high proportion of the landscape and comprises between 6 and 15% of the total NT rainforest extent. The Tiwi Islands also include nearly 200 km 2 of “treeless plains”, a vegetation type largely restricted to these islands.

The lack of knowledge concerning Verhuellia is largely due to its restricted distribution, poorly known collection localities, limited availability in herbaria and absence in botanical gardens and lack of material suitable for molecular phylogenetic studies until recently. Because Verhuellia has some of the most reduced flowers in Piperales, the reconstruction of floral evolution which shows strong trends towards reduction in all lineages needs to be revised. † Methods Verhuellia is included in a molecular phylogenetic analysis of Piperales (trnT-trnL-trnF and trnK/matK), based on nearly 6000 aligned characters and more than 1400 potentially parsimony-informative sites which were partly generated for the present study. Character states for stamen and carpel number are mapped on the combined molecular tree to reconstruct the ancestral states.
