Research and Collaboration Projects
- Formulating a risk assessment of
of New Zealand mud snail on macroinvertebrates in the Madison River, MT
and Firehole and Gibbon Rivers of Yellowstone National Park.
- Characterizing the effects of
and hydroelectric operations in the Snake River, ID on threatened
serpenticola (Bliss Rapids Snail) with David Hopper US Fish and Wildlife Service..
- New Zealand Mud Snail web site
up to date information on distribution, publications and resources with
USFWS Aquatic Nuisance Species Task Force, and Dan
- Characterizing Myxozoan types and
cerebralis infection on the Madison River, MT with Leah Steinbach
MSU and Richard Vincent MT Fish, Wildlife and Parks.
- The viability of Myxobolus
myxospores after passage through the alimentary canal of avian
in the Greater Yellowstone Ecosystem with Leah Steinbach Elwell MSU and
Todd Koel Yellowstone National Park.
- Myxobolus cerebralis in
trout of 3 spawning tributaries to Yellowstone Lake: a qualitative
risk assessment with Silvia
Murcia in collaboration with Todd Koel of Yellowstone National
Silvia has examined whirling disease infection in Yellowstone
trout over several seasons and is correlating this to physicochemical
in three tributaries. Silvia has used tools such as sentinel cage
trout, histology, and PCR to assess the magnitude of infection in the
and location of clinical infection within cutthroat trout.
- The spatial dynamics of Myxobolus
infection in drainages within Pelican Valley of Yellowstone National
in collaboration with Todd Koel of Yellowstone National Park, and Jim
and Charlotte Rasmussen of USGS Western Fisheries Research
Julie spent her first field season in 2004 determining the locations of
"hotspots" for M. cerebralis parasite release from tubificids
the Pelican drainage in Yellowstone Park. She is using molecular
tools to determine the species of parasite and the prevalence of
of Tubifex tubifex in the Pelican Valley at the USGS
Western Fisheries Research Laboratory, Seattle, WA. We aim to
tools for managers to predict whirling disease concentrations and M.
cerebralis success by combining these types of data.
- Whirling disease risk and
integrity in Montana watersheds with Stephanie
McGinnis. Stephanie has been manipulating one of the
largest whirling disease data sets ever collected. She is using
and sentinel cage data and from Blackfoot, Rock Creek, Madison and
River watersheds from 1997-2000, and GIS land use data to identify
among biological stream integrity, anthropogenic disturbances and
disease. The goal is to identify watershed characteristics that
whirling disease risk and contribute to the development of effective
practices for Montana watersheds.
