GLIN==> Upcoming Seminars

[Kanika Suri <Kanika.Suri@noaa.gov>]

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

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.
