http://www.baikalscience.org Scientific research about Lake Baikal Thu, 30 Oct 2008 12:35:01 +0000 http://backend.userland.com/rss092 en An important paper soon to be published synthesizes a suite of datasets collected by three generations of biologists working on Lake Baikal (Hampton et al. 2008). In this study, time-series of lake-water temperature, zooplankton and phytoplankton were taken off-shore from Bol'shie Koty at better-than-monthly resolution since 1945. A shorter record ... http://www.baikalscience.org/?p=65 PFCs (perfluorochemicals) are man-made compounds used in many industrial processes. They are commonly used in fire extinguishers and as CFC replacements in refrigerators, as well as being essential in computing, cosmetic and medical industries. They are also used to make non-stick pots & pans and stain-proof fabrics. PFCs have been ... http://www.baikalscience.org/?p=63 The Holocene (a term first coined in the early 19th century) is the most recent and current interglacial. The start of the Holocene record is one of the most easily identified features in palaeoclimatic records, although accurately dating this start has proved challenging. The start of the Holocene was commonly ... http://www.baikalscience.org/?p=58 Prokopenko, A.A., Khursevich, G.K., Bezrukova, E.V., Kuzmin, M.I., Boes, X., Williams, D.F., Fedenya, S.A., Kulagina, N.V., Letunova, P.P. & Abzaeva, A.A. 2007. Paleoenvironmental proxy records from Lake Hovsgol, Mongolia, and a synthesis of Holocene climate change in the Lake Baikal watershed. Quaternary Research 68, 2-17 doi:10.1016/j.yqres.2007.03.008 http://www.baikalscience.org/?p=59 There is great debate about the impacts of recent climate change on ecosystems around the world, especially with regard to whether impacts are ‘natural’ or linked to increasing temperatures associated with increasing greenhouse gases (GHGs). Over the last c. 1000 years, three distinct phases of climate are often classified in ... http://www.baikalscience.org/?p=47 Kalmychkov, G.V., Kuz’min, M.I., Pokrovskii, B.G. Kostrova, S.S.

Lakes present a special case for diversity studies: they vary greatly in age and type but exist as discrete and discontinuously distributed units that occur in most ... http://www.baikalscience.org/?p=41
