    Fields survey of freshwater fishes in Upper Wang River, North Thailand

    ABSTRACT
    The present paper reports a fields survey of freshwater fish in Upper Wang River, at Jae Hom District, Lumpang Province, North Thailand in September 2013. We found 11 families and 16 species of freshwater fishes. Hampala macrolepidota Kuhl et van Hasselt, 1823 and Mystacoleucus marginatus (Valenciennes, 1842) (Cypriniformes Cyprinidae) are dominant in transparent and running fast stream ecosystem while Pangio anguillaris (Vaillant, 1902) (Cypriniformes Cobitidae) is a dominant in turbid and running slowly stream ecosystem. One species, Channa cf. gachua (Hamilton, 1822) (Perciformes Channidae), still has an unclear taxonomic status. The Thai local names and distribution data of freshwater fishes are provided.

    The first record of Trigonostigma somphongsi (Meinken, 1958), a critically endangered species, in its natural habitat of Thailand (Cypriniformes Cyprinidae)

    ABSTRACT
    A population of a critically endangered Trigonostigma somphongsi (Meinken, 1958) has been discovered in a deepwater rice field, floodplain of Bangpakong Basin, Nakhornnayok Province, central Thailand. The population was the first record of this species in its natural habitat since its description by Meinken in 1958. The species appeared to be a seasonal horizontal migration species, since it migrates to breed in the floodplain during the rainy season between July and November and migrates back into the main channel during the dry season.

    Two new records of cyprinid fish (Cypriniformes Cyprinidae) from Thailand

    ABSTRACT
    In the present paper, two cyprinid fishes, Boraras urophthalmoides (Kottelat, 1991) and Rasbosoma spilocerca (Rainboth et Kottelat, 1987) are newly recorded from Bangpakong Basin, Southeast Thailand. Description and distribution data of the two cyprinid fish are provided here.

    Newly reported marine red alga, Neosiphonia savatieri (Hariot) M.S. Kim et I.K. Lee, 1999 (Rhodophyta Rhodomelaceae) from Thailand

    ABSTRACT
    Neosiphonia savatieri (Hariot) Myung Sook Kim et In Kyu Lee, 1999 is reported for the first time from Thailand based on specimens collected from the Gulf of Thailand and Andaman sea. We herein describe the vegetative and reproductive morphology of the specimens. Important features for species identification include the thallus configuration, number of pericentral cells, cortication, branching pattern, origin of rhizoids, origin of branches, occurrence of trichoblasts and reproductive characteristics. Our results expand the known geographic distribution of this species and confirm its taxonomic features.

    A stability assessment on seasonal variation of seaweed beds in the Trat peninsula of Thailand

    ABSTRACT
    Species diversity, biomass and distribution pattern of seaweed beds in the Trat peninsula, east coast of Thailand, were investigated in relation to environmental conditions from January to December 2011. The macroalgal samples and environmental factors were collected monthly; covering cool-dry (January-February, November-December), hot-dry (March-April) and rainy (May-October) seasons at four sampling stations; Ao Cho, Ao Lane, Laem Tien and Laem Sok. A total of 26 taxa of marine benthic algae were recorded, of which 16 species of red marine algae were the most diverse group. It was found that Catenella nipae, Gracilaria salicornia, Gelidium pusillum, Hydropuntia changii, Hypnea hamulosa, Kyrtutrix maculans, Laurencia decumbents, Lyngbya majuscula, Peyssonnelia rubra and Ulva clathrata were the most abundant throughout the sampling period. The highest number of marine flora species was obtained in March (25 species), whereas the lowest in June (12 species). Algal biomass had a maximum value in April (59.50 g/m2 dry weight) and minimum value in July (20.14 g/m2 dry weight).
