Welcome to LUCCI!
LUCCI is a research centre at Lund University devoted to studies of the carbon cycle and how it interacts with the climate system. The centre involves about 120 researchers from four Lund university departments: Physical Geography and Ecosystem Science, Geology, Biology and Physics.
Deoxynation of the Baltic sea
2014-04-07: Professor Daniel Conley, Department og Geology, have been participating in an international study on the deoxynation on the Baltic Sea. The results are published in the March issue of PNAS (Proceedings of the National Academy of Sciences of the United States of America).
The results show that the deoxygenation of the water close to the floor of the Baltic Sea has tenfolded the last 115 years. In 1900 the affected seafloor covered an area of 5000 square kilometers, while 2012 that area was more than 60 000 square kilometers. Deoxynation leads to the death of animals in those waters, and also disturbs the balance of the sea ecosystem.
The researchers find leakage of nutrients and climate responsible for the change.
-Politicians in the countries related to the Baltic sea must actively work to reduce the leakage of nutrients. Otherwise the state of the Baltic sea will be even worse, Daniel Conley says.
Fossilized chromosomes found in Royal Ferns
2014-03-21: Geology professor Vivi Vajda, Lund University, has made some remarkable findings together with fellow researchers at the Swedish Museum of Natural History, Benjamin Bomfleur and Stephen McLoughlin. In Scania, southern Sweden, they have found fossils from a Royal Fern that at an age of 180 million years still have well kept cell nuclei and chromosomes.The findings are described in an article in the current issue of Science.
The dating has been set to the early jurassic, when the landscape of what is now southern Sweden was of tropical character, dominated by dinosaurs. Volcanoes was a common feature of this period, and it is thanks to them that the fern fossil is still so very well preserved.The plant that is now in the scientific limelight, was instantly covered by the flows of the vulcano about 180 million years ago, and everything going on in the plant stopped with no decay processes reaching it.
- There is even well preserved cells kept in the phase of cell division, Vivi Vajda says to Lund University.
The researchers have studied the fossils with microscope, x-ray and geochemical techniques, and doing that they found nucleus, membranes and even chromosomes. Findings that are extremely rare in fossils.
The actual fossil was found in the 1960s. It was collected and then forgotten in the archives of the Swedish Museum of Natural History. 40 years later the research group started to pay attention to it, which has now resulted in remarkable this finding and an article in Science.
Mild winters a problem for forestry
2014-03-14: The mild winter means trouble for the forestry in the north of the country, as the grounds are not frozen and cannot take the weight of the big machines. Climate change and milder winters and the effects of that is highlighted in a feature of science news radio magazine "Vetandets värld" at swedish raio. LUCCI member Anna Maria Jönsson participates and is interviewed about her research on the spruce bark beetles, and what effects the climate change have on their dynamics.The feature from the excursion was also sent in October.
