Queen Nest Location of the weaver ant, Oecophylla smaragdina, in Thailand

A study on the queen nest location of weaver ant (Oecophylla smaragdina; Family: Formicidae) was carried out during 2013-2014 in Thailand. This study aims in attempt to record the, size, structure, location, and facing direction of queen nest. The queen nest was recognized by the presence of a large number of workers guarded and protected by in comparison with non ... Read More »

Notes on Dendrobium elliotianum O’Byrne (Orchidaceae), a poorly know orchid from Thailand

The occurrence of Dendrobium elliotianum O’Byrne in Thailand represents the first reporting of this species. The Dendrobium elliotianum O’Byrne, a poorly known orchid, was newly discovered in northern (and southwestern) Thailand. It was previously known from cultivated plants. It is similar to D. gregulus Seidenf.and D. garrettii Seidenf and it is here suspected that it has frequently been mistaken for ... Read More »

Population Density and Morphometry Analysis for Sex Determination in Varanus salvator from Bangkachao, Samutprakran Province

The study investigated the population density and morphometric analysis for sex determination of the water monitor (Varanus salvator) in Bagkachao, Prapadaeng, Samutprakran province, using mark capture-recapture during January 2012 to December 2012. Twenty six live-traps were placed every month (286 trap-days in total) and each reptile was tagged with a passive integrated transponder (PIT tag). Forty one lizards were recaptured ... Read More »

Tree Distribution across the Forest Ecotone of Lower Montane Forest at Doi Sutep-Pui National Park, Chiang Mai Province

A study of the tree distribution across the forest ecotone of lower montane forest (LMF) was carried out at Doi Sutep-Pui National Park, Chiang Mai province during 2014. The objectives aimed to clarify the species composition and determine environmental factors for coexisting tree species. A permanent transect plot, 30 × 600 m, was established from 900 to 1,100 m above ... Read More »

Variations in Plant Diversity and Carbon Storage among Subtype Communities in a Dry Dipterocarp Community Forest of Mae Tha Sub-district, Mae On District, Chiang Mai Province

Variations in plant diversity and carbon storage among subtype communities in a dry dipterocarp forest were investigated in the Mae Tha sub-district community forest, Mae On district, Chiang Mai province, in 2014. Fifteen sample plots, each 40 x 40 m, were used for vegetation survey and arranged randomly over the forest. Plant data in these plots were collected by measuring ... Read More »

Spatial Biomass Variation, Biomass Dynamics and Species Diversity in Relation to Topographic Factors of Lower Tropical Montane Forest

Forest biomass and biomass dynamics were used in this study of forest structure and environmental assessment as one of the most important criteria in order to understand forest ecosystem status and forest equilibrium. This research approach evaluated the effects of topographic indices consisting of elevation, slope aspect, slope inclination and index of convexity (IC) on the live-tree, aboveground biomass (AGB), ...

Analysis of phylogenetic relationship between sacred lotus and woody plants using nucleotide sequences of rbcL and its adjacent genes

Sacred lotus (Nelumbo nucifera Gaertn.) was morphologically considered the same family of water lilies, Nymphaeaceae, in spite of its difference in palynology and floral development. The further investigation genetic variation was to determine different in polymorphism. The chloroplast rbcL and adjacent genes were selected from three wild-type Thai lotus cultivars, Klong Yong (KY), Nong Nan (NH) and Rachine (RC). The ... Read More »

Soil Characteristics and Carbon Storage in Forest Soil of Mae Ya Noi Community Forest, Chom Thong District, Chiang Mai Province

Soil characteristics and carbon storage were studied in the forest soils of Ban Mae Ya Noi community forest, Chom Thong district, Chiang Mai province. Twelve plots (40×40 m) were selected using stratified random sampling along the latitudinal gradient. One soil pit was made in each plot and soil samples were collected down the profile for analysis of physical and chemical ... Read More »
