The diversity of acorn barnacles (Cirripedia, Balanomorpha) across Thailand’s coasts: The Andaman Sea and the Gulf of Thailand

Four species of Thinolestris Grootaert & Meuffels are known so far, including T. nigra sp. nov., which is described here from Singapore, Malaysia and Brunei. New morphological data on the genus are given. At the moment, Thinolestris is only known from Andaman Sea, Strait of Singapore, South China Sea, Celebes Sea, Bismarck Sea and the Coral Sea. It is not yet known from North Australia nor from the Gulf of Thailand, or farther north. Thinolestris adults are active on beaches with small pebbles mixed with sandy patches. It is not found on rocks, pure sandy beaches nor mangroves.

Abstract We examined the diversity and host use of sponge-associated barnacles of Thailand (Andaman Sea and the Gulf of Thailand) using a combined morphological and molecular approach. Eight barnacle species (including two new species) were collected from 12 host sponges. Host-specific barnacle species includes Acasta lappasp. nov., which exclusively inhabits the sponge Mycale sp. Acasta milkaesp. nov. was only collected from the sponge Callyspongia cf. diffusa (Ridley, 1884). Multatria filigranus (Broch, 1916) were found in the encrusting soft sponges Monanchora unguiculata (Dendy, 1922) and Clathria sp. Pyrgospongia stellula (Rosell, 1975) inhabits the sponges Spheciospongia vagabunda (Ridley, 1884). Generalist barnacle species includes Euacsta ctenodentia (Rosell, 1972), E. porata (Nilsson-Cantell, 1921), E. zuiho (Hiro, 1936), and Acasta cyathus Darwin, 1854, which inhabit a wide range of sponges with various textures.

Ornate threadfin bream (Nemipterus hexodon) is an economically important fishery species in Southeast Asia. In Thailand, N. hexodon decreased dramatically due to overexploitation for commercial purposes. To construct an effective sustainable management plan, genetic information is necessary. Thus, in our study, the population genetic structure and demographic history of N. hexodon were investigated using 419 bp of the mitochondrial DNA sequence in cytochrome oxidase subunit I gene (mtDNA COI). A total of 142 samples was collected from nine localities in the Gulf of Thailand (Chonburi, Samut Songkhram, Surat Thani, Nakhon Si Thammarat, Songkhla), and the Andaman Sea (Satun, Trang, Krabi, Phang Nga). Fourteen polymorphic sites defined 18 haplotypes, revealing a high haplotype diversity and low nucleotide diversity among nine localities. The Analysis of molecular variance (AMOVA) analysis, pairwise FST, and minimum spanning network result revealed that the genetic structure of N. hexodon was separated into two populations: the Gulf of Thailand and the Andaman Sea population. The genetic structure of N. hexodon can be explained by a disruption of gene flow from the geographic barrier and the Pleistocene isolation of the marine basin hypothesis. Neutrality tests, Bayesian skyline analysis, mismatch distribution, and the estimated values of population growth suggested that N. hexodon had experienced a population expansion. The genetic information would certainly help us gain insight into the population genetic structure of N. hexodon living on the coast of Thailand.

The Thai commercial fleet can carry about 10% of the volume of imports and exports. History of Thai maritime trade is divided into 1) Sukhothai period era 2) Ayutthaya and Thonburi period 3) Rattanakosin period 4) The first of the national fleet period. .Sukhothai period era trade with various foreign countries. In the King Ramkhamhaeng era is a prosperous.. 1) The Gulf of Thailand trade with China 2) Trade on the Andaman sea is a merchant ship from India. Ayutthaya and Thonburi period. Traders of various nationalities come to trade. The Gulf of Thailand (South China Sea) and the Indian Ocean. Trading in Ayutthaya is a monopoly trade, operated by monarchs and noblemen.Rattanakosin period Thailand entered into a Treaty of Burney, the outcome of the agreement was that the country had to cancel its monopoly trade and the end of trade by the government. The growth of the trade has increased. The production structure from the old to be self-transformed into production for export. The first of the national fleet period 1918 - 1925 After the First World War I King Rama VI established a Thai merchant fleet in April 1918, the name of Siam Commercial Maritime Company Limited. It was terminated in 1925. On June 22, 1940, the cabinet approved the establishment of Thai Maritime Navigation Company Limited for international maritime shipping. The The cabinet was terminated in 2011 .The role of Thai National Maritime Navigation.The merchant fleet were not growing. Because lack of and thai merchant fleet too small, there was a lack of negotiating power with the foreign merchant fleet. The government must set up a policy to promote the merchant fleet.

Isthmus Of Kra

This paper is a conceptual study that attempts to analyse the possible effects of the development of the Kra Isthmus Canal on ASEAN relations. The Kra Canal would constitute a mega-project, a passageway that would connect the Andaman Sea and the Gulf of Thailand at the Isthmus of Kra, Thailand. Although the proposed Kra Canal is projected to provide many economic and trade benefits to Thailand, and to the region as a whole, steps toward its development have yet to be taken. There has been much debate over the costs for trade, the costs for the environment, national and regional security concerns, as well as major concerns related to political and economic relations in the region. Therefore, one of the main purposes of this study is to contribute to the debate on the possible impact of the development of the Kra Canal on ASEAN's regional relations. In particular, it proposes that the development of the Kra Canal could threaten regional solidarity as it would physically divide maritime Southeast Asia from mainland Southeast Asia, which would ultimately result in an economic, cultural and political divide of ASEAN itself.
