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: Electrons in the fast lane

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.

Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
