Ralph Grundel, PhD
My research focuses on reducing extinction risk in animals and restoration of landscapes.
I lead a team that focuses on improving the scientific basis for conservation of pollinators and savanna landscapes, improving landscape connectivity, reducing extinction risk for threatened and endangered species, and documenting the effects of climate change on species and landscapes, especially in the Great Lakes region and in support of national parks. I work out of the USGS Great Lakes Science Center’s Lake Michigan Ecological Research Station within Indiana Dunes National Park.

Is the timing, pace and success of the monarch migration associated with sun angle? Is the timing, pace and success of the monarch migration associated with sun angle?
A basic question concerning the monarch butterfly’s fall migration is which monarchs succeed in reaching overwintering sites in Mexico, which fail—and why. We document the timing and pace of the fall migration, ask whether the sun’s position in the sky is associated with the pace of the migration, and whether timing affects success in completing the migration. Using data from the Monarch...

Balancing sampling intensity against spatial coverage for a community science monitoring programme Balancing sampling intensity against spatial coverage for a community science monitoring programme
Community science is an increasingly integral part of biodiversity research and monitoring, often achieving broad spatial and temporal coverage but lower sampling intensity than studies conducted by professional scientists. When designing a community‐science monitoring programme, careful assessment of sampling designs that could be both feasible and successful at meeting programme goals...

The integrated monarch monitoring program: From design to implementation The integrated monarch monitoring program: From design to implementation
Steep declines in North American monarch butterfly (Danaus plexippus) populations have prompted continent-wide conservation efforts. While monarch monitoring efforts have existed for years, we lack a comprehensive approach to monitoring population vital rates integrated with habitat quality to inform adaptive management and effective conservation strategies. Building a geographically and

A call to insect scientists: Challenges and opportunities of managing insect communities under climate change A call to insect scientists: Challenges and opportunities of managing insect communities under climate change
As climate change moves insect systems into uncharted territory, more knowledge about insect dynamics and the factors that drive them could enable us to better manage and conserve insect communities. Climate change may also require us revisit insect management goals and strategies and lead to a new kind of scientific engagement in management decision-making. Here we make five key points...

Oriental bittersweet (Celastrus orbiculatus): Spreading by fire Oriental bittersweet (Celastrus orbiculatus): Spreading by fire
In many forest ecosystems, fire is critical in maintaining indigenous plant communities, but can either promote or arrest the spread of invasive species depending on their regeneration niche and resprouting ability. We examined the effects of cutting and burning treatments on the vegetative response (cover, stem density) and root resources of Oriental bittersweet (Celastrus orbiculatus)...
