Abstract:
... Distribution of PM₀.₁, PM₁ and PM₂.₅ particle- and gas-polycyclic aromatic hydrocarbons (PAHs) during the 2019 normal, partial and strong haze periods at a background location in southern Thailand were investigated to understand the behaviors and carcinogenic risks. PM₁ was the predominant component, during partial and strong haze periods, accounting for 45.1% and 52.9% of total suspended particul ...
... Asterinales is an important epifoliar order which generally lacks of DNA-based sequence data. There are many genera in Asterinales lacking molecular data and the exact taxonomic placement of those genera is undetermined. In this study, we introduce Brunneofissuraceae fam. nov. and Cirsosia mangiferae sp. nov. and Asterina neomangiferae nom. nov. based on morpho-molecular evidences. All fungal spec ...

Abstract:
... Spatial interpolation methods usually differ in their underlying mathematical concepts. Each has inherent advantages and disadvantages, and choosing a method should be based on the type of data to be analyzed. This paper, therefore, compares and evaluates the performances of well-established interpolation techniques that can be used to estimate monthly rainfall in Thailand. The approaches analyzed ...

Abstract:
... All members of the ant genus Odontomachus Latreille, 1804 are venomous ants. Four species in this genus have been identified from Thailand: Odontomachus latidens Mayr, 1867; O. monticola Emery, 1892; O. rixosus Smith, 1757; and O. simillimus Smith, 1758. The three latter species are available and have been used for an outline morphometric study. They display similar morphology, which makes their d ...

Abstract:
... Antennae and maxillary palpi are the most important sensory organs involved in the behaviors of black flies. The ultrastructure of sensilla on these sensory appendages of two human-biting black fly species, Similium nigrogilvum and Simulium umphangense, was studied for the first time. Wild adult females of both species were collected in Umphang District, Tak Province, western Thailand. The morphol ...

Abstract:
... This study explored the perspectives of elephant mahouts (n = 55) and tiger caregivers (n = 18) working in 4 private or 2 government facilities in Thailand to learn their experiences and viewpoints pertaining to use of animals in tourism. Interviews were conducted in Thailand at facilities in four cities. Mahouts working in private tourism facilities used one-to-one management and were significant ...

Abstract:
... The ant subfamily Dorylinae consists of the true army ants and non-army ant genera. The biology of these non-army ants is important in discussing the evolution of the army ant adaptive syndrome. We report on the colony composition, morphological characteristics, and phasic reproduction of a non-army doryline ant Cerapachys sulcinodis species complex collected in northern Thailand. Colony size was ...

Abstract:
... Commercial processing is potentially a confounding factor for elemental profiling in shrimp. Here, two sets of paired samples were collected pre/post-processing from the same farms; one set from Thailand (n = 15) and one from Ecuador (n = 19). The samples from Ecuador were subjected to a meta-bisulfite bath as part of the processing regimen while the samples from Thailand were subjected to a salt ...

Abstract:
... The distribution, characteristics, and ecological risk of microplastics in beach sand and seawater samples collected along the shore of Rayong province, Thailand, were investigated in this study. The average microplastics abundance in beach sand and seawater was 338.89 ± 264.94 particles/kg d.w. and 1781.48 ± 1598.36 particles/m³, respectively. Beach sand and seawater had the most yellow-brown par ...

... AbstractA new genus of minute stingless bees (Meliponini: Hypotrigonina) is described from Southeast Asia. Ebaiotrigona Engel & Nguyen, gen. nov., is based on the type species Lisotrigona carpenteri Engel, recorded from Vietnam, Thailand, Laos, Cambodia, and southern China. The species was previously considered an enigmatic member of Lisotrigona Moure, but is removed to a new genus based on its u ...

Abstract:
... Estimating flood hazard, vulnerability, and flood risk at the household level in the past did not fully consider all relevant parameters. The main objective of this study is to improve this drawback by developing a new comprehensive and systematic methodology considering all relevant parameters and their weighting factors. This new methodology is applied to a case study of flood inundation in a mu ...

Abstract:
... Farms in Asian newly industrialised economies are increasingly faced with operational and structural challenges (e.g. small farm size, ageing of farmers). Public policies have generally focused little on several of these structural challenges or on links between the challenges facing farms. The future of these farms looks uncertain. However, in Thailand, multi-stakeholder dialogue on this future h ...

Available habitat and hence the global population of the Endangered giant nuthatch Sitta magna, restricted to lower montane habitats of south-western China, eastern Myanmar and northern Thailand, remains poorly quantified. Thailand is the only portion of the species’ range for which there is a population estimate. To obtain a more precise estimate of the Thai population and clarify the extent and ...
