The barbels of the subfamilies ´Poropuntinae´ and Smiliogastrinae within family Cyprinidae play a significant role as food source for fish in artisanal fisheries are highly valued ornamental Thailand. In this study, we employed both conventional molecular cytogenetics to analyze karyotype 15 species from two cyprinid lineages. All analyzed had diploid chromosome number 2n = 50. Despite sharing same 2n, our analyses revealed species-specific distribution patterns mapped microsatellite motifs...
Fish species were collected by electrofishing from 96 sites, representing 79 species, in lightly exploited rivers western Thailand. Significant chemical and physical environmental factors associated with numbers total fish abundance identified using multiple linear regression. Total correlated negatively water depth temperature (r = 0.4, p < 0.05), whereas positively river discharge elevation 0.6, 0.05). Chemical that significantly influenced distribution determined partial least squares...
Carbon and nitrogen stable‐isotope ratios were compared of fin muscle tissue from 15 fish species collected seven headwater rivers in eastern western Thailand. In addition, two‐source mixing models used to derive estimates each fish's reliance on allochthonous autochthonous energy based tissues. Across the dataset, was enriched 13 C relative by c . 1·5‰. Variation δ N between tissues below statistically significant levels. Estimates resource use calculated average 15% greater than those...
The catfish family Siluridae contains 107 described species distributed in Asia, but with some Europe. In this study, karyotypes and other chromosomal characteristics of 15 from eight genera were examined using conventional molecular cytogenetic protocols. Our results showed the diploid number (2n) to be highly divergent among species, ranging 2n = 40 92, modal frequency comprising 56 64 chromosomes. Accordingly, ratio uni- bi-armed chromosomes is also variable, thus suggesting extensive...
Microplastics (MP) have accumulated in environmental components including aquatic organisms.In this study, we investigated MP accumulation the local dominant shellfish, i.e. 150 individual assassin snails (Anentome helena) and 60 clams (Pilsbryoconcha exilis compressa), sampled from 39 sites headstream, midstream downstream areas of Khwae Noi Basin western Thailand.MP was found to be only filamentous type approximately 26.0% 38.3% occurrences with averages 0.5±1.0 2.5±3.3 pieces/individual,...
Stream degradation increases with high anthropogenic activity and climate variability, while declines occur in biodiversity. However, few studies have been undertaken on tropical waterways, a major impediment to biodiversity conservation. The present study was conducted 95 relatively pristine small streams Eastern Thailand 10 reasonably uncommon species of balitorid fishes. Measurements were made 21 physical chemical factors the substrate particle size. Stepwise regression identified direct...
Biocomposites sheets were prepared by compression molding from mixtures of corn starch plasticized glycerol as matrix and cellulose fibers, extracted used office paper, reinforcement filler with contents ranging 0 to 8% wt/wt fibers matrix. Properties composites determined mechanical tensile test, differential scanning calorimetry, thermogravimetric analysis, water absorption measurement, electron microscopy. The results showed that higher content raised the strength elastic modulus up 109%...
The popularity of sesarmid crab Episesarma singaporense (Tweedie, 1936) in Thai and Southeast Asian cuisine has put the species under pressure.However, sesarmids are important for nutrient cycling within mangrove ecosystems, losses due to overfishing could have a wide impact.Although reproductive system been well reported, our study aimed describe male E. detail, using light electron microscopy.We elucidated histological characters tract, including anterior, median posterior vas deferens,...
Nutritional profiles and food safety are being concerned with consumers in recent years because they directly involved human health. Researches into favorable nutritional heavy metal contamination of rice a foundation for future security. In this study, we studied compared morphologies, chemical compositions, bioactive compounds, Paka-umpuel local (PLR) variety from Surin province, Thailand, which nine PLR samples were divided two groups based on different cultivation processes: four organic...
Abstract The taxonomy of the Parachela–Oxygaster–Macrochirichthys clade Xenocyprididae has been confused since original descriptions Parachela oxygastroides and hypophthalmus in mid‐19th century. confusion seems attributable to substantial intraspecific variation color other morphological characteristics species Oxygaster . Morphological data on 401 specimens from throughout range molecular phylogenetic analyses indicate that six available names for are valid: cyanea , P. ingerkongi...
Seasonal change inferred to climate inevitably influences Critical thermal maximum (CTmax) of riverine fishes. In this study, we investigated CTmax as tolerance for four common fishes, i.e., Danio regina, Channa gachua, Rasbora caudimaculata and Mystacoleucus chilopterus, in the Kwae Noi river system western Thailand. The acute was lower wet season (mean temperature ∼25 °C) higher dry ∼23 with medians season-CTmax those fishes 35.3 ± 0.4, 36.2 0.5, 37.3 0.5 37.5 0.6 °C, respectively, high...
Five species of Glyptothorax are identified from the Mae Klong River basin in western Thailand, only one which, G. buchanani, was previously reported basin; others lampris, longinema, platypogonides, and schmidti. The morphological differences delineating were visualized using principal component analysis data taken 105 specimens, latitudinal range number river basins over which all occur found to be greater than recognized. recently thought as far north peninsular occurs Chao Phraya...
The main aspects of solid waste management in an area are the quantities, compositions and characteristics, as well its current situations. Elephant Study Center (or Village), known by Thais foreigners, presently lacks data on generated including management. This study investigated quantities using purposive sampling containers, according ASTM D 5231-92 standard, some i.e. bulk density, moisture content total solid, weighting weight differences. In addition, problems, community participation...
An investigation was conducted to clarify the role of oxidative stress and ultrastructural changes on sperm silver barb, Barbonymus gonionotus caused by cryopreservation. The cryopreserved using a dry shipper 500-μl straws loaded with 160 μl extended semen 10% DMSO, frozen for 2 min within upper chamber shipper, immediately transferred into lower cryostorage. Lipid peroxidation (LPO) levels barb were affected freezing cryostorage period, progressively increasing (p < 0.01) throughout 14-day...
