New species of shrimp found in Songkhla Lake

29.06.2010
Prof. Dr. Saowapa Angsupanich and a research team from the Department of Aquatic Science, Faculty of Natural Resources have found 2 new species of amphipod or shrimp-like animal in Songkhla Lake soil sediment.

One was Karmaka songkhlaensis which were 2-3 millimeters in size, and named after the location in which they were found. They were in abundance in the upper part of the Lake with low level of salinity (about 1-4 parts per thousand) and were also found spreading to the middle part and the lower part in the rainy season when the level of salinity decreases.

The other type was Kamaka appendiculata , 2-3 millimeters in size. They were found in highly saline area (25-33 parts per thousand) and densely populated in the lower part from the mouth of the Lake to Yo Island.

The new species are important to Songkhla Lake ecology. Being food for fish and shrimps, they are part of the food chain. They can help reduce the rotten waste at the Lake bed because they eat organic matters in the soil sediment and they help with the circulation of air and water in the sediment through the holes they live in. Both species of shrimps are found off the coast towards the center of the Lake where the water and sediment are still somewhat clean. The Lake has been contaminated from the coast because there are villages, piers, agricultural activities and industries.

Prof. Dr. Saowapa Angsupanich said that the discovery of these new species was a by-product of the research about animals at the bed of Songkhla Lake. In the past 20 years, data about all living things have been continuously collected: planktons, animals at the bottom of the Lake, seaweeds, sea grass and other animals. The researchers wanted the data to be known among the locals and all the Thais and so asked for a grant from Thailand Research Funds to produce a handbook about Songkhla Lake for secondary school students, teachers, and the general public and a handbook specializing in the study of animals at the bed of Songkhla Lake under the research project titled “Knowledge transfer from the study of animals at the bed of Songkhla Lake to the local community” which are now underway. It is believed that the information from this series of book will be able to raise the local people’s awareness of the value of resources in their own areas and to have common ideas in conserving Songkhla Lake.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
