New shrimp species found in Songkhla Lake

30.11.2011
Prof. Dr. Saowapa Angsupanich and a research team from the Department of Aquatic Science, Faculty of Natural Resources, Prince of Songkla University, Thailand, have discovered 2 new species of shrimp in Songkhla Lake soil sediment.

The first, Karmaka songkhlaensis, 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 other shrimps, they are part of the food chain. They can help reduce the rotten waste at the Lake bed because they eat organic matter 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 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 by 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: plankton, seaweed, sea grass and other animals. The researchers wanted the data to be known among the locals, 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 is now underway.

It is believed that the information from these books 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: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Studying fundamental particles in materials

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
