Article
Full-text available
Cirolana phuketensis sp. n. was collected from coral rubble from the Andaman sea coast of Thailand. C. phuketensis sp. n. is described and fully illustrated; C. phuketensis sp. n. can be recognized by the presence of transverse sutures on pereonites 2–4, pereonite 7 having three transverse sutures forming a nodulose ridge, antennula peduncle with a...
Article
The dispersal pattern of microorganisms has been a debated topic in the last decade, because for microscopic organisms with dispersing stages, biogeographic barriers may not exist and geographic distances may have little effect on the probability of their occurrence. In this study we tested whether a group of microscopic animals, the bdelloid rotif...

Four new species of the Cirolana ‘parva group’ from shallow coastal habitats in Thailand are described: Cirolana andamanensis sp. nov. and C. phangnga sp. nov., from the Andaman Sea, and C. siamensis sp. nov. and C. thailandica sp. nov. from the Gulf of Thailand. Molecular (The cytochrome oxidase subunit I gene) analysis incorporating taxa from the...
Article
We test the hypothesis that conochilid rotifers represent an independent family-level taxon within Superorder Gnesiotrocha, by analysing their phylogenetic position based on the 18S rDNA sequence of a large number of representatives of this taxon and its putative relatives. Both Bayesian and maximum likelihood analysis confirm a monophyletic clade...
Article
The freshwater littoral comprises a mosaic of habitats structured at several scales by a combination of hydrophyte architecture and physiology. Within this complex environment littoral invertebrates should distribute themselves to maximize fitness: that is, for sessile animals selection of permanent substrata is critical, while distribution of moti...

Cirolana songkhla sp. n. was collected from brackish-water habitats including lagoons and estuaries in the coastal zone of the lower Gulf of Thailand. C. songkhla sp. n. is described and fully illustrated; C. songkhla sp. n. can be recognized by the presence of abundant chromatophores dorsally, lack of ornamentation on the posterior pereonites, ple...

We provide a checklist of the freshwater Rotifera recorded from Thailand, based on a review of available literature. Approximately 398 species of rotifers are recorded. The rotifer fauna of Thailand has been investigated quite comprehensively and these studies focus on four main parts of the country: the northern, north-eastern, central and souther...

Four species of amphipods from the families Aoridae and Maeridae were collected from Thai Waters in 2011. Three species, Grandidierella phetraensis sp. nov., Ceradocus andamanensis sp. nov. and Parelasmopus siamensis sp. nov. are new to science and Bemlos quadrimanus (Sivaprakasam, 1970) has not been previously reported from Thai Waters. Their char...

Following previous reports indicating a remarkable high diversity of sessile rotifers in Southeast Asian freshwaters, we report on an extensive study of the diversity of Collothecidae rotifers from fifteen freshwater habitats in Thailand. A total of 13 species, including two additional infraspecific variants, of Collothecidae are recorded, one of w...
Article
Full-text available
Two new species of maerid and melitid Amphipoda, Maeropsis paphavasitae and Rotomelita longipropoda, respectively, collected from a seagrassbed of the Lower Gulf of Thailand, are described. Maeropsis paphavasitae is characterized by it seven teeth on the palm of gnathopod 2 and Rotomelita longipropoda can be recognized by its long gnathopod 1 propo...
Article
Full-text available
A new species of Grandidierella is described from the Inner Gulf of Thailand. This species inhabits high saline waters of abandoned saltpans from the Samut Sakorn district, Thailand. It appears to be closely related to Grandidierella propodentata Moore, 1986, also collected at hypersaline environments, in having an accessory fl agellum; and arbores...

In response to a clear gap in knowledge on the biodiversity of sessile Gnesiotrocha rotifers at both global as well as re-gional Southeast Asian scales, we performed a study of free-living colonial and epiphytic rotifers attached to fifteen aquat-ic plant species in Thale Noi Lake, the first Ramsar site in Thailand. We identified 44 different taxa...
Article
Full-text available
A study of zooplankton communities in three rice fields (RF1, RF2 and RF3) at Pathum Thani province was carried out from August to November 2005. A total of 88 taxa were identified. Of these, 74 belonged to Rotifera, 11 were Cladocera and 3 were Copepoda. The highest number of zooplankton species was recorded in RF1 (75 species), followed by RF2 (5...

Full-text available
The amphipod Tethegeneia khanomensis sp. nov. were collected from South Sea Islands, lower Gulf of Thailand. in March 2008. A total of twelve species from seven families was recorded. The common and dominant species were Paradusa bilobata and Podocerus andamanensis occurred in all stations. The six species are new record for the Gulf of Thailand an...
Article
Population dynamics of Noctiluca scintillans (Macartney) Kof. et Swezy containing the photosynthetic endosymbiont Pedinomonas noctilucae (Subrahman.) Sweeney was investigated in relation to environmental conditions in the upper Gulf of Thailand. A clear association was observed between the abundance of N. scintillans and the monsoon cycle, with its...
Article
Full-text available
At present, 99 species of cladocerans are known from Thailand, but up to ten more have not been identified to species, particularly in Chydorus, Ephemeroporus and Pleuroxus. Cosmopolitan species are a minority, while wide-ranging circumtropical taxa are an important element, beside species that only occur in the tropics-subtropics of two continents...
Article
Full-text available
A total of 133 rotifer species was identified from five coastal peat swamps on Phuket Island. Of these, Dicranophoroides sp.A and Harringia rousseleti were new to Thailand. The most speciose genus was Lecane (30.82%), followed by Lepadella (12.03%). The highest species richness occurred in Jae-Son (100 species), followed by Jik (84 species), Jood (...
Article
Full-text available
In order to assess the recovery potential of tropical freshwater communities after disturbance, we performed an experimental study on the effects of exposure conditions and durations of storage on hatching of rotifer resting eggs in sediment. Well-mixed surface sediment samples from Mai Khao peat swamp on Phuket Island, Thailand, were stored under...
Article
Full-text available
Seventy-two cladoceran species from southern Thailand include eleven first records. Species accumulation curves were used to estimate the total number of species present, and Chaos estimator was used to extrapolate the species number observed in 212 samples to the total number present. This S*max amounted to 76.06 species, with a low ratio of varia...

A total of 96 species was ide...
Article
The life history of a marine dinoflagellate Pyrophacus steinii (Schiller) Wall et Dale was investigated using clonal cultures isolated from Tokyo Bay. The asexual reproduction is binary fission of the eleutheroschisis type. All processes of asexual and sexual cell division occur inside the theca of the mother cells. Sexual reproduction is anisogamo...

The archeopyle type in modern dinoflagellate cysts is classified into the following saphopylic, theropylic and cryptopylic types. Within the saphopylic type, Tuberculodinium vancampoae (=cyst of Pyrophacus steinii) is the only species generally accepted as having an archeopyle developed on the hypocyst. However, the archeopyle type of this species...

Article
Two clones ofAlexandrium cohorticula were isolated at Aburatsubo, Sagami Bay, Japan. Cultured cells of both contained high amounts of paralytic shellfish toxins. The toxicity of these isolates was comparable with that of highly toxic Thai clones. No significant difference in toxin components or their proportions was observed between Japanese and Th...
