GLIN==> Upcoming Seminars



Happy New Year! We have two NOAA/ University of Michigan Great Lakes Seminars scheduled for the week of January 9. Please find details for both events listed below.

1) Speaker: *Dr. Yi Luo*, Professor, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing, China

Title: " Development of the distributed eco-hydrological simulator DEHydroS with application in irrigation districts of the Yellow River basin"


Date: Wednesday, January 10.


Time: 10:30 AM

Location: Great Lakes Environmental Research Laboratory, 2205 Commonwealth Blvd, Ann Arbor, MI, 48105

Abstract:
This talk presents the development of the Distributed Eco-Hydrological Simulator DEHydroS and its application in the irrigation districts of the Yellow river Basin. DEHydroS was developed from the CERES-wheat and maize, SWAT2000, and MODFLOW models. The first half of the talk will introduce how, in the DEHydroS, the crop ecological, hydrological, and groundwater processes coupling was realized. Irrigated agriculture plays an important role in the Yellow River basin. It is the largest water user and grain producer of the basin. Irrigation districts rely heavily upon the water supply from the Yellow River. However, as the discharge of the Yellow River has been decreasing and the competition for water among different uses has been increasing, the challenge to sustainable development of the irrigated agriculture in the basin is enormous. The second half of the talk will demonstrate applications of the DEHydroS model in the irrigation districts of the Yellow River . Finally, the problems and lessons learned will be discussed for modeling of irrigated agriculture in the Yellow River Basin.



2) Speaker: Steve Pothoven <http://www.glerl.noaa.gov/about/pers/profiles/pothoven>, Fishery Biologist, GLERL


Title: "/Hemimysis anomala/ - the newest Great Lakes invader"

Date: Thursday, January 11.

Time: 10:30 AM

Location: Great Lakes Environmental Research Laboratory, 2205 Commonwealth Blvd, Ann Arbor, MI, 48105

Abstract:
/Hemimysis anomala/ (G.O. Sars, 1907), a Ponto-Caspian crustacean (Mysidacea), was identified in November 2006 in the channel between Lake Michigan and Muskegon Lake. Large numbers of individuals formed aggregations averaging 1540 ± 333 individuals/m^2 . The population included females (63%), males (35%) and juveniles (2%), and some females were in a reproductive condition. Thus the population appears to be reproducing. It was stocked into water-bodies in southern part of the former Soviet Union to provide food for fish food and was first observed as an invader in the Kaunass reservoirs in the Baltic Sea basin (Lithuania) in 1962. It has since spread to other areas including the Baltic Sea proper (1992), River Rhine (1997), and the United Kingdom (2004). /H. anomala/ is an omnivorous feeder, consuming both zooplankton and phytoplankton, has a high feeding rate and can switch feeding modes with ontogeny or as food availability changes. The species is found predominantly over hard bottom areas such as rocks or zebra mussel beds and is found less frequently over sandy or silty bottoms or in areas overgrown with aquatic vegetation. The hidden life-style of this species makes it difficult to assess its geographic distribution. Research is needed to assess 1) the distribution of H. anomala in the Great Lakes basin, and 2) the likely impacts on both the Great Lakes and inland lake ecosystems.
