Ray Moranz

Lead Insect Ecology Field Technician

Primary Role: Studying ecology of grassland invertebrates in the Grand River Grasslands of southern Iowa and northern Missouri
I work with Dr. Diane Debinski to obtain, analyze, and interpret data on the responses of invertebrates and floral resources to patch-burn grazing and other prairie management practices in the Grand River Grasslands. Some of our research foci include:

  • Studying responses of butterfly populations to changes in nectar source availability
  • Evaluating the effects of environmental variables on butterfly communities and populations
  • Comparing different sampling methods for assessing butterfly abundance

In May 2010, I received my Ph.D. in Natural Resource Ecology and Management from Oklahoma State University, where I studied the effects of fire and grazing on prairie flora and invertebrates.  

 

Jen Vogel

Post-doctoral Research Associate

My research interests are in the areas of restoration ecology and fire management. I am interested in how management and restoration decisions affect habitat and wildlife in grassland ecosystems.

I received my Ph.D. in Ecology and Evolutionary Biology in December 2011 from Iowa State University. My dissertation research focused on bird responses to vegetation diversity in restored grasslands in Northwest Iowa. I completed my M.S. degree at Iowa State in 2006 studying butterfly responses to prairie restoration using fire and grazing in the Loess Hills of Iowa.

Rhea von Busse

Post-doctoral Research Associate

I am very interested in biomechanics, specifically in animal flight. I have been working on bat flight for most of my scientific career and am currently transitioning into research on butterfly flight. I am trying to take complex situations and behaviors from the field into simplified and controllable conditions in a wind tunnel. With this approach I want to study butterfly behavior, kinematics, and aerodynamics in the context of habitat edge effects.
 
I completed my masters degree at the Ludwig-Maximilians University in Munich, Germany, and, while in collaboration with Lund University in Sweden, I became intrigued by the kinematics and aerodynamics of nectar feeding bats. I continued the collaboration with Lund University during my dissertation and received my doctorate from the Humboldt University Berlin, Germany in 2011. My research focused on the trinity of energy conversion: kinematics, aerodynamics, and energetics of bat flight. I just finished a postdoc position at Brown University, where I extended my bat flight research to more energetics work and the X-ray reconstruction of moving morphology (XROMM).

John Delaney

Graduate Student

I am a PhD student in the Debinski lab, working on the patch burn grazing project.  My research interests include butterfly/host plant interactions and the use of nectar sources by butterflies in a patch burn grazing system.  In general I am interested in prairie restoration and management and the preservation of rare species.  My other interests include hiking, camping and biking.

Kim Szcodronski

Graduate Student I joined the Diane Debinski lab in Spring 2012 and I am currently working on my M.S. degree. My research interests include restoration ecology, conservation biology, and the effects of climate change on the environment and its species. In particular, I am conducting a habitat selection analysis of the montane butterfly Parnassius clodius in Grand Teton National Park. The known habitat preferences of Parnassius clodius were used to develop a habitat model and GIS-based analysis will be used to predict where other potential habitats may exist for this butterfly species in the Greater Yellowstone Ecosystem.

Karin Grimlund

Graduate Student I am a new graduate student in the Debinski Lab, and I am pursuing a Master's degree in Ecology and Evolutionary Biology.  Currently, I am studying patch-burn grazing practices in the Grand River Grasslands of southern Iowa and the potential for fire and grazing interactions to reduce tall fescue abundance and/or alter endophyte infection rates in tall fescue.  I am also involved in research on native pollinator responses to different types of grassland management.  In general, I am interested in conservation biology and ecological restoration of natural communities, particularly in the upper Midwest.  My professional and research interests are broad and include: insect ecology and conservation, multifunctional agriculture, environmental education and outreach, and invasive species ecology and management.

Tori Pocius

Graduate Student I joined the Debinski Lab in the fall of 2014; I am pursuing a Ph.D. in Ecology and Evolutionary Biology.  I plan to study how the patch-burn grazing processes impact nectar production in native milkweeds in the Grand River Grasslands of Southern Iowa.  In particular, I am interested to see how nectar production varies among species, if nectar availability influences oviposition preference in monarch butterflies, and how climate change will impact future milkweed species distributions.  In general, I am interested in pollinator conservation, plant-insect interactions, restoration ecology, environmental education and outreach, and global change biology. 

Hilary Haley

Graduate Student I am a graduate student in the Debinski lab and am pursuing a M.S. degree in Ecology and Evolutionary Biology.  In general, my interests include conservation biology, restoration ecology, botany, and native pollinator conservation.  To better understand the long term effects of habitat restoration on native pollinator populations, I’m currently studying the abundance and diversity of native bees found on prairie remnants and reconstruction plantings in the Grand River Grasslands.

MJ Hatfield

Technician

My work as a prairie enthusiast/amateur ecologist turned student focuses on insects, their prairie host plants and life cycles. For some insects a specific host plant is required, for others any number of host plants will do. If you can identify the prairie plants then you already know the food and shelter of some prairie insects. An example of this is the sunflower tortoise beetle, Physonata helianthi, always associated with sunflowers, often associated with sawtooth sunflower, Helianthus grosseserratus. Anthropomorphically speaking the beetles are cute and the larvae are clever with their protective shield of excrement and shed skins situated on their urogomphi. Another example is the cloudless sulphur butterfly, Phoebis sennae, whose gorgeous larvae eat partridge pea, Chamaecrista fasciculata.

Jenny Hopwood

Technician

I sorted insects for the Iowa River Corridor and Patch-Burn Grazing projects in the Debinski lab, and also taught biology labs here at ISU. I am interested in pollinator biology, and particularly enjoy learning about bees.

Will Reed

Technician

I studied how songbirds and birds of prey assess habitat at the landscape scale using flyover data collected at Neal Smith National Wildlife Refuge.

I also studied how avian communities change on restored prairie through stages of restoration (with Brian Olechnowski)

Mike Rausch

Technician/Independent Study Student

I worked with Sheri Svehla sorting insect sweeps samples for the patch-burn grazing project in the Grand River Grassland of Iowa.

Rob Todd

Undergraduate Science With Practice (SWP) Student

Science With Practice Project:  I worked with the PBG team entering plant, insect, and bird data.  I focused on the interactions between different Coleopteran groups and the plant species Festuca Arundinacea (Tall Fescue).  Previously I have worked on sorting and entering data from the order Coleoptera.

Lisa Stream

Undergraduate Science With Practice (SWP) Student

Science with Practice project: Patch Burn Graze

I conducted research on the prairie insect responses to burning and grazing. I worked with Sheri Svehla sorting invertebrate samples collected in the summer field seasons. The 2007 Science with Practice project explored the statistical relationship between the richness of grazed versus ungrazed prairies. In 2008, the project explored the effect of burning on prairie species richness.

Laura Winkler

Technician

I recently completed an undergraduate degree in Entomology. I have been working as a technician identifying invertebrates from the Patch Burn Grazing study to examine insect responses to burning and grazing treatments. I am particularly interested in studying the ant responses.
