​

Dr. Derek Rosenberger is an associate professor of biology, co-director of the ONU Biological Sanctuary (OBS) and coordinates the Zoology and Environmental Science Programs at Olivet Nazarene University in Bourbonnais, IL. His research program seeks to include highly talented undergraduate students in conservation biology, studying species, population and community level ecology in threatened and endangered ecosystems. Research interests also include invasive forest insects and their potential for impacting native ecosystems.

 

In his teaching Rosenberger seeks to engender wonder at the incredible diversity of creation, help students become passionate about its care and discover new things through scientific investigation. He achieves this through course-based undergraduate research experiences (CUREs) and through annual summer field ecology and research trips to Costa Rica and Alaska.

 

Dr. Rosenberger obtained his Ph.D. in Entomology and Conservation Biology at the University of Minnesota and spent several years as the Program Director of the Creation Care Study Program in Belize, Central America. He has a Masters in Higher Education focused on environmental literacy from Taylor University and a Bachelors degree in Biology and Environmental Science from Messiah University. Rosenberger studied abroad in India through Au Sable Institute of Environmental Studies and completed the Educational Concerns for Hunger Org. (ECHO) Tropical Agriculture and Development year-long training program.

Studying Conservation in Illinois
and around the world

Olivet Nazarene University is surrounded by high quality examples of two critically endangered ecosystems, the tallgrass prairie and Midwestern oak savanna. Our lab focuses on studying the organisms that depend upon these habitats. 

 

While tallgrass prairie has declined by 99.9% in Illinois, ONU has several acres of newly restored prairie on campus, and access to over 70 acres of restored prairie just off campus. The ONU Biological Sanctuary, just 15 minutes from campus, contains 100 acres of restored prairie, marsh, riparian forest and vernal pool habitat along 3/4 of a mile of the biodiverse Kankakee River. ONU is 30 minutes from some of the best remnant black oak savanna on Earth at TNC's Kankakee Sands Macrosite. We are 40 minutes east and 30 minutes west of two American bison conservation herds roaming1000 acre prairie pastures situated in 20,000 acre preserve systems.

​

We are also involved in tropical research in Costa Rica, where we are studying the biodiversity of insects and frogs on elevational gradients in the cloud forests and paramo (alpine) of the Talamanca mountains at the Quetzal Education and Research Center. 

Research Projects

Research in the Rosenberger Lab is focused on the community ecology of endangered ecosystems as well as insect invasion biology in natural communities. Our work is accomplished through partnerships with organizations like the USDA-Forest Service, The Illinois Nature Conservancy, The Quetzal Education and Research Center and others. Research is carried out under the direction of Dr. Derek Rosenberger with students in Olivet's Honors Program and other highly motivated and bright students in Olivet's dynamic Zoology and Environmental Science Programs.

Prairie bumble bee conservation

Some species of bumble bees have experienced severe declines over the last 50 years in the Midwest. We are involved in several projects including determining population stability of the bumble bees of conservation concern in local prairies and savannas, determining bee community composition and ecological interactions at Midewin National Tallgrass Prairie, and determining the effects of cattle and bison grazing on bumble bee populations.

Oak savanna and tropical cloud forest scolytine and wood boring beetle communities

Much work has been done on the role of bark and ambrosia beetles as pests of forests in North America. However, little is known about their community ecology and the role that habitat factors play in these communities. Our lab is investigating these communities in various ecosystems, including in the endangered savannas of the American Midwest and along elevation gradients in tropical montane cloud forests and paramo in Central America.

Red-headed woodpecker conservation

Red-headed woodpeckers were once one of the most common woodpeckers in the Midwest. However, in recent years they have declined by 70% or more. It is unclear what factors have led to this decline. We are investigating foraging behavior, and factors associated with healthy woodpecker populations in an attempt to discover what may help this species recover.

Bark beetle range expansion

Bark beetles are important forest disturbance agents, particularly in coniferous  forests in Western North America. Due to warming temperatures, one particularly destructive beetle, the mountain pine beetle, has begun to move eastward through the Canadian boreal forests after crossing warmed mountain passes in 2006. My work with Dr. Brian Aukema (Univ. of MN) and Dr. Robert Venette (USDA-FS) investigates the suitability of novel hosts for the insect in an attempt to discern the impact it may have on natural systems in eastern North American and Eurasia.

Prairie Restoration at ONU

In July 2018 we begin a tallgrass prairie restoration project at ONU. That has now expanded to the management of the 100 acre Swanberg Biological Sanctuary composed of restored prairie, marsh, savanna and riparian forest on the banks of the Kankakee. Our studies have included plant, small mammal, ground beetle, solitary bee, bumble bee and butterfly surveys.

Courses

Fall Semester

Invertebrate Zoology

Invertebrates make up a majority of the animals on Earth. To understand animals we must understand the invertebrates. This course introduces students to the invertebrate Phyla, with special emphasis on the major groups, particularly Arthropoda and the Insects. Students create museum-grade insect collections and conduct both field studies and lab work to learn key knowledge and skill sets in the study of invertebrates.

Spring Semester

Animal Behavior

Understanding the behavior of animals is key to understanding their morphology and natural history. In this course we study the key aspects of animal behavior from ants and beetles to elephants and whales. The lab is primarily research based, with students designing and carrying out animal behavior studies using ethograms and other methods in close consultation with Dr. Rosenberger. Nearby bison herds are also utilized.

Fall Semester

Environmental Science and Society

Many environmental issues face our society today. Understanding the science behind these issues and the ways that scientists approach the mitigation of these problems is important for any informed and active member of our society. This class can be taken as a general education course or with the inclusion of a lab, as a major course for degrees in the Biology Department. The optional lab provides detailed exploration of course content through skill-building environmental assessment labs and observational field trips.

Spring even years

Ornithology

Birds are the most species rich and abundant vertebrate that most people are likely to encounter. The diversity of avian morphology, life history and behavior is extraordinary. But basically, they are just fun to study! Ornithology focuses on avian studies with an emphasis on learning field studies techniques and identification of all breeding birds and many migrants found in our region. Labs are nearly entirely in the field, however field trips to nearby world class museums and zoos are also utilized.

Spring odd years

Conservation Biology

Ecologists today can no longer simply study interactions and processes in nature, we must also realize the threats that face biodiversity today. This course explores the nature of extinction and the causes and procese that take a population down that path, but also emphasizes the actions to recover species. Labs develop skills and engage organizations and professionals in the field.

Summer

Tropical and Arctic Field Ecology Courses

The Tropical and Arctic Field Ecology courses are a chance to participate in ecological field studies at the extremes. Courses include 7 weeks of meetings each spring, followed by several weeks in the field in Costa Rica or Alaska. Extensive travel and study occurs throughout many ecosystems and biomes. Ecological field studies techniques are utilized throughout the course. Research projects are completed at biological field stations and presented during the fall semester to the department and at Homecoming.
