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: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
