Research projects conducted from the Museum largely address
aspects of biodiversity in relation to various land use situations. Most
of these projects are components of the graduate programs of M.S. and Ph.D.
students and are funded by a variety of state and federal agencies. Other
projects that are being conducted by the Museum Director address phylogenetic
questions. Some of our projects are as follows:
The aquatic insect fauna of Thailand.
We have been collecting aquatic insects in Thailand for the past 15 years
and have taken over 1,000 samples from throughout the country. As such, we
have many thousands of vials of specimens representing all aquatic orders.
With cooperating systematic specialists for various families and higher taxa,
Dr. Akekawat Vitheepradit (Kasetsart University) and I are endeavoring to
prepare an exhaustive reference for the aquatic insects of Thailand, to include
taxonomic keys to the genera of all aquatic insect forms. Dr. Michael Whiting
will conduct molecular fingerprinting to match unknown larvae with identifiable
adults for the problematic Odonata, Coleoptera, and Diptera. We are currently
searching for a source to fund this project.
Re-establishment of the lentic fauna of ponds along the Andaman Sea coastline
following the Tsunami (NSF)
Samples were taken at four time intervals following the devastating tsunami
of 2004. Approximately 20 ponds along the coastline in Thailand were chosen,
roughly half within the devastated area and half further inland, to determine
the rate at which the lentic insect fauna becomes re-established. In addition,
a series of peat swamps were sampled and the results will be compared with
those of Watanasit (1995) for direct pre- and post-tsunami sampling.
Biodiversity and biogeography of aquatic Heteroptera of Thailand (NSF)
The aquatic Heteroptera fauna of distinct mountainous regions from the northern
regions near Chiang Mai through the Isthmus of Kra to Malaysia will be examined
and community similarity examined to determine if a natural barrier to the
distribution of species exists at a definable point in the latitudinal distribution
of the mountains. Further, particular ubiquitous species will be selected
and molecular genetics examined to estimate the degree to which the mountains
act to isolate populations.
Elevational zonation of Heteroptera communities in northern Thailand (NSF)
The aquatic Heteroptera fauna will be sampled at distinct elevational increments
on Doi Inthanon and Doi Suthep to determine if the communities in what ways
the communities are associated with elevation. Many new species are being
described in the following families: Aphelocheiridae, Helotrephidae, Naucoridae,
Nepidae, Gerridae, Veliidae, and more.
Phylogeny of Naucoridae
The family Naucoridae includes 36 currently recognized genera, which have
been assembled into 5 subfamilies. No phylogenetic analysis has been performed
on these taxa, in part because of the difficulty in using morphological characters.
Thus, we are conducting a phylogenetic analysis using both morphological and
molecular data. Currently, we are trying to obtain as many genera as possible
in 100% etOH. We sincerely thank Herbert Zettel (Natural History Museum -
Vienna) and Michael Whiting (Brigham Young University) for providing some
important SE Asian and other genera for our use.
Lotic insects associated with natural springs in Missouri (MDNR)
The goal of this study
was to examine aquatic insect, amphipod, and isopod communities and associated
habitat gradients in eight low discharge rheocrene spring systems in the prairie
and Ozark regions of Missouri. Taxon presence and density will be associated
with a suite of environmental parameters.
Odonata of Missouri prairie ponds (UMC)
Larval Odonata were sampled from >100 prairie ponds in northern Missouri
and community associations with existing ecoregionalization schemes and vegetation
zones analyzed. Many range extensions were recorded and taxonomic enigmas
Descriptions of immatures (UMC)
Immature stages of assorted species of Naucoridae from various parts of the
world are being described. These specimens were collected during sampling
for other ecological and faunistic projects.
