Both hydropower dams and global warming pose threats to freshwater fish diversity. While the extent of may be reduced by a shift towards energy generation large in order reduce fossil-fuel use, such profoundly modify riverine habitats. Furthermore, posed will interact: for example, constrain range adjustments fishes that might compensate temperatures. Evaluation their combined or synergistic effects is thus essential adequate assessment consequences planned water-resource developments. We...
Abstract Fishes have adapted a number of different behaviors to move out the water, but none been described as being able walk on land with tetrapod-like gait. Here we show that blind cavefish Cryptotora thamicola walks and climbs waterfalls salamander-like diagonal-couplets lateral sequence gait has evolved robust pelvic girdle shares morphological features associated terrestrial vertebrates. In all other fishes, bones are suspended in muscular sling or loosely attached pectoral anteriorly....
Abstract Flow of terrestrial carbon though aquatic ecosystems (allochthony) is an important but underestimated component the global cycle. A lack clear consensus about importance allochthonous (terrestrial) organic sometimes attributed to uncertainties associated with conventional ‘bulk’ isotope data, most widely used ecological tracer. Amino acid‐specific analysis emerging research method promising address existing limitations bulk C and N analyses. We tested efficacy amino acid δ 13 data...
River-floodplain ecosystems are in delicate balance and impacted by even minor changes water availability. In this study, we surveyed fish assemblages investigated environmental landscape parameters a total of 135 floodplain waterbodies (rivers, diversion canals, ponds, irrigation ditches, paddy fields, wetlands) the Chao Phraya River Basin rainy (September 2014) dry (March 2015) seasons. Factors affecting species richness each type waterbody were analyzed using generalized linear mixed...
The rheophilic hillstream loaches (Balitoridae) of South and Southeast Asia possess a range pelvic girdle morphologies, which may be attributed to adaptations for locomotion against rapidly flowing water. Specifically, the connectivity plate (basipterygium) vertebral column via sacral rib, relative size shape fall within spectrum three discrete morphotypes: long, narrow rib that meets basipterygium; thicker, slightly curved meeting robust crested interlocking with basipterygium. Species in...
ABSTRACT Balitorid loaches are a family of fishes that exhibit morphological adaptations to living in fast flowing water, including an enlarged sacral rib creates ‘hip’-like skeletal connection between the pelvis and axial skeleton. The presence this rib, robustness which varies across family, is hypothesized facilitate terrestrial locomotion seen family. Terrestrial balitorids unlike any known fish: resembles tetrapods. Emergence convergence from water land has been studied fossils;...
The first chromosomal characteristics of nucleolar organizer regions (NORs) and karyological analysis triangle butterflyfish (Chaetodon triangulum) yellow (C. andamanensis) from Andaman Sea, Phuket Phang Nga Province, Thailand, were studied. Kidney cell samples taken five male female fish. Mitotic chromosome preparations conducted using standard squash technique as well directly kidney cells. Metaphase spreads performed on microscopic slides then air-dried. Conventional Ag-NOR banding...
Karyological characteristics of the Barramundi, Lates calcarifer (Bloch 1790) from Andaman Sea, Thailand, were analyzed in present study. Kidney cells two male and female fish directly used mitotic chromosome preparation. The preparations conducted kidney cells. Chromosomes stained by using conventional staining Ag-NOR banding techniques. results showed that diploid chromosomes number L. was 2n=48 fundamental (NF) 54 both sexes. types comprise 2 large metacentric, submetacentric,...
We investigated the relationship between environmental variables as descriptors of fish community, in terms species diversity indices and assemblage patterns, seagrass meadows at Sikao Bay, Trang Province, Thailand. Fish data water quality parameters were collected from January to December 2012. A total 10,596 specimens 97 taxa 48 families four stations, Kham Bay (7°30'9.21''N, 99°18'7.67''E), Boonkong (7°31'2.49''N, 99°17'40.09''E), Ban Pak Klong (7°36'17.67''N, 99°16'32.89''E) Sai Cape...
Physoschistura chulabhornae, new species, is described from Maechaem River, a tributary of Ping upper Chaophraya River drainage, Chiangmai province, Thailand. It distinguished all other known species in having an incomplete lateral line reaching at least to the origin anal fin with 62-83 lateral-line canal pores, dorsal-fin slightly front pelvic-fin origin, no axillary pelvic lobe, and suborbital flap shape hammer head male.
We report the first chromosome analysis in Indian vagabond butterflyfish (Chaetodon decussatus) and lined (C. lineolatus) from Andaman Sea, Phuket Province, Thailand. Kidney cell samples were taken four male female fishes. The mitotic preparation was directly prepared kidney cells. chromosomes stained with conventional Ag-NOR staining techniques. results showed that diploid number of C. decussatus lineolatus 2n=48, fundamental (NF) 48 both males females. present as large telocentric medium...
Schistura maejotigrina, new species, is described from Maechaem River, a tributary of Ping in the upper Chao Phra-ya River drainage, Chiang Mai Province, Thailand. It distinguished all other species having 21–24dark tiger-stripe black bars on side body and 6½–7½ branched dorsal soft rays. The medium-sized,reaching 53.0 mm SL (69.6 TL), known only system, northernChao Phraya basin, lives fast running, clear water over substrate mixed gravel, small stone sand.
Length-weight relationship (LWR) was used as a tool to assess the status of fish stocks, through condition factor, in major rivers Thailand. Fifty-one (51) species from each river, i.e., The examined for LWR using eleven years monitoring data (2010–2020) Bang Pakong and 14 (2007–2020) Chao Phraya, which comprised 57,871 samples. parameters factor were by body shape, ovate, oblong, elongate or eel-like. coefficient determination (r2) all log-transformed LWRs greater than 0.90. Parameter b...
Schistura sirindhornae, a new species of nemacheilid, is described from the Nan River basin in northern Thailand. It distinguished all other having overlapping scales on entire body similar to balitorids, transparent belly and thorax, lateral-line canal that most cyprinids balitorids being present across surface scale instead represented only by pore. also has unique color pattern irregular brown bars back side faint yellow-orange body, bright triangular orange mark occiput, an crown-shaped...
