Freshwater biomonitoring with macroinvertebrates in East Asia
This paper summarizes the history and current status of efforts to implement macroinvertebrate biomonitoring protocols for surface water pollution in China, Japan, South Korea, Malaysia, Mongolia,
Biodiversity in South East Asia: an overview of freshwater sponges (Porifera: Demospongiae: Spongillina)
Diversity and distribution of SE Asian inland water sponges is reported on the basis of available literature and a recent biodiversity assessment of the Lower Mekong basin, with the highest diversity recorded from Indonesia, Philippines, Thailand, and Myanmar.
Life history patterns of stream-dwelling caddis
Intraspecific variation in development rates, the wide range of size classes present at one time, the ability to overwinter in different larval stages and the asynchronous extended flight periods may be evidence of a spreading of risk within life histories.
Development of rapid bioassessment approaches using benthic macroinvertebrates for Thai streams
Hampered by incomplete taxonomic knowledge of benthic macroinvertebrates in Thailand, family-level identification may be sufficient taxonomic resolution for rapid bioassessment in Thailand.
Biodiversity assessment in the Lower Mekong basin: First record of the genus Oncosclera (Porifera: Spongillina: Potamolepidae) from the Oriental Region
The description of a new species from the Pong River (NE Thailand, Oriental Region) in the framework of a biodiversity assessment in the Lower Mekong Basin, which differs from all the other known species of the genus in its unique combination of diagnostic traits.
Biodiversity Assessment Of The Lower Mekong Basin: A New Species Of Corvospongilla (Porifera: Spongillina: Spongillidae) From Thailand
The new species Corvo- spongilla siamensis nov. sp. differs from all the other known species of the genus in its unique combination of diagnostic traits, particularly a) acanthostrongyles (megascleres), b) gemmuloscleres, both in the cage and in the theca, as strongyles showing the tendency towards ring-shape and button-like shape.
The alderfly genus Indosialis Lestage, 1927 (Megaloptera: Sialidae) in Thailand and Laos, with a description of a new species.
The pupal stage of Indosialis siamensis is reported here for the first time and the new species coexists with I. bannaensis in Loei Province, northeastern Thailand.
The length-weight relationships, condition factors and gut contents of Syncrossus helodes (Sauvage, 1876) and Yasuhikotakia modesta (Bleeker, 1864) from the Mekong River, Muang District, Nong Khai
It was concluded that S. helodes and Y. modesta are carnivores from the Mekong River and both exhibited positive and negative allometric growth in the dry-hot and thedry-cool season, respectively.
Predatory Foraging Behaviour and Activity Patterns of Larvae of Two Species of Limnephilid Cased Caddis
Larvae of both Potamophylax cingulatus and Halesus radiatus showed a similar endogenous rhythm of activity consistent with the species being nocturnal and were most active at night during a 4 h period (2000-2400 h).
