RESEARCH AT UNDERGRADUATE INSTUTITONS (RUI) FUNDED RESEARCH
WITH THE MONGOLIAN AQUATIC INSECT SURVEY (MAIS)
I received a Research
at Undergraduate Institutions, Biotic Inventories
Grant through NSF early September 2009 (DEB-
BS&I # 0816910). The focus of this
research is to combine basic ecological research
with the description of biological diversity of
chironomids. The research will be completed
in conjunction with on-going research by the MAIS
project (see below) and will include range
condition data for use by all participants.
A focal question of this phase of my
research is whether variation in grazing intensity
in Mongolia impacts diversity of chironomids.
Currently, I have two undergraduate students from Wayne
State College who are working with me to
develop protocols to measure range condition and
to work on macroinvertebrate diversity from
streams in Mongolian and Nebraska steppes.
This research project provides a natural
link to my research on Chironomidae Pupal Exuviae
in Nebraska (CPEN).
Streams in Nebraska and Mongolia flow
through steppe systems which are grazed.
Students who work on either/both the
RUI-MAIS and CPEN projects are encouraged to make
comparison between the natural history of
Mongolian and Nebraska streams.
Mongolian Aquatic Insect Survey began as the Selenge River
Project (SRP) conducted from 2003-3006. Both
projects have been funded by the National
Science Foundation’s Biodiversity
through Dr. Jon
Gelhaus and the Academy of
Natural Sciences of Philadelphia to discover, document, and
describe diversity of aquatic macroinvertebrates from Mongolia. The
SRP and MAIS projects have fostered a spirit of international
collaboration between scientists in the U.S., Mongolia, Lithuania, and
other countires. Check out the MAISwebpage

project. I have been on expedition to collect aquatic insects in
Mongolia five times, beginning in 1995 with work on Lake Hovsgol
(check here for Long
Term Ecological Research in Lake Hovsgol). Currently, my part in
the project is to work with Chironomidae on these projects and work on
biological assessment and conservation of aquatic habitat in Mongolia.
final report has been
submitted to NSF and my research in Mongolia has resulted in the
total of 238 species of Chironomidae from five subfamilies have
now been documented from Mongolia. Here
is a checklist of Mongolian
Chironomidae. I will add to
this list as researchers continue to publish new discriptions and
discoveries of Mongolian Chironomidae.
of Chironomidae has high turnover rates between streams in the
Gorkhi Terelj region of Mongolia, resulting in high gamma
diversity for these study sites.
contributed significantly to changes in sediments, dissolved
oxygen, and pH in Mongolian streams. Other large scale
variables such as elevation and latitude, and small scale
variables such as substrate also contributed significantly to
variation in water quality variables.
from research on the impact of riparian range condition on water
quality of Nebraska streams is mixed. Initially stream
sediments decreased with increased evidence of grazing in streams
from the Nebraska Pine Ridge (see
results here). However, subsequent research on streams in
the Verdigris Creek and Bazile Creek watersheds indicate that
those streams have increased sediment corresponding to increased
habitat and water quality data from the SRP and MAIS aquatic
habitat sites can be accessed on the MAIS
work on chironomids in Monglolia includes work by Ferrington and
Bouchard on chironomids from lakes. Here is their Identification
Guide to Chironomid Pupal Exuviae of Mongolian Lakes.
