Nachusa 2020 Science Publications

By Elizabeth Bach
​Ecosystem Restoration Scientist
​With 2020 drawing to a close, Nachusa science has several accomplishments to recognize:
  • Nearly 40 Blanding’s turtle hatchlings were released after “head-starting.” This is the result of seven years of on-going research from Dr. Rich King, Tom Anton, Dave Mauger, and Jess Fliginger and partnerships with Richardson Wildlife Foundation and the Forest Preserve Districts of DuPage and Lake counties. Learn more in this blog post from Jess Fliginger.

  • Nine eastern prairie fringed orchid seedlings were transplanted to Nachusa Grasslands as part of on-going research from Dr. Betsy Esselman and colleagues into developing methods to restore populations of this endangered plant.
  • Citizen scientists completed annual odonate (8th consecutive year), RiverWatch (7th consecutive year), and frog calling (4th consecutive year) surveys, using appropriate social distancing.

  • Friends of Nachusa Grasslands allocated over $47,000 to support research at Nachusa through their grants program.
  • Several scientists have received major external grants to do research at Nachusa Grasslands. These include new projects and continue building long-term datasets for existing work.
  • Fifteen peer-reviewed scientific publications have included data from Nachusa Grasslands in 2020. 

Science Publications

Scientific publications are the product of years of hard work, collecting and analyzing data as well as writing the paper. I’d like to use this blog post to highlight some of this recently published research.

prairie restoration
It has been an exciting year for Dr. Holly Jones, Dr. Nick Barber, and their lab groups. Holly and Nick began research at Nachusa Grasslands in 2013 as new faculty at Northern Illinois University (Nick is now at San Diego State University). Their work investigates restoration outcomes related to planting age, prescribed fire, and grazing. In 2020, the team has published five papers:
  • Heather Herakovich found Prescribed Fire Has a Greater Impact on Artificial Nest Predation Than a Recent Bison Re-introduction in Illinois Tallgrass Prairie as part of her PhD dissertation research. Using artificial nests with artificial eggs, she found in the year immediately after a prescribed fire, nest success was lower and predation rates were higher. Field mice were the most common nest predator.
  • Melissa Nelson and Sheryl Hosler, who earned their Masters’ from NIU in 2019, examined Reintroduced grazers and prescribed fire effects on beetle assemblage structure and function in restored grasslands. Older restorations supported more large-bodied, carnivorous, and nocturnal species beetles. Remnant beetle communities most closely resembled mid-age restorations. Bison presence shifted the ground beetle community slightly, and prescribed fire had no overall effects on the beetle community.
  • Ryan Blackburn, who earned his MSc in 2018, published two papers from his work examining management impacts on plant communities and bison diets at Nachusa. In Plant Community Shifts in Response to Fire and Bison in a Restored Tallgrass Prairie Plant Community Shifts in Response to Fire and Bison in a Restored Tallgrass Prairie, Ryan found Restoration age was a main driver of differences in plant community. Ryan also found Reintroduced bison diet changes throughout the season in restored prairie. The majority of bison diets are grass, and about one third of Nachusa bison diets include flowering plants (including legumes).
  • Angie Burke looked at Early Small Mammal Responses to Bison Reintroduction and Prescribed Fire in Restored Tallgrass Prairies in her MSc thesis. She found more small mammals in new restorations and recently burned areas, driven largely by shifts between voles and mice in the community. You can learn more about her findings in this blog post.

ornate box turtle
The Wildlife Epidemiology Lab, led by Dr. Matt Allender, at the University of Illinois Urbana-Champaign has included Nachusa Grasslands as one of their sites in on-going health evaluations of wild turtle populations. Research scientist Dr. Laura Adamovicz has published three papers from her PhD dissertation:
  • In Erythrocyte sedimentation rate and hemoglobin-binding protein in free-living box turtles (Terrapene spp.), Dr. Adamovicz found adding blood lab-work to traditional health metrics for wild turtle populations correlated strongly with other measures of wild turtle health, and are less biased across season, population, and years.
  • In Plasma antibacterial activities in ornate (Terrapene ornata) and eastern box turtles (Terrapene carolina), anti-bacterial capacity of blood differed between the two species of box turtle.
  • Building on the previous results, Plasma complement activation mechanisms differ in ornate (Terrapene ornata ornata) and eastern box turtles (Terrapene carolina carolina) showed that the two species of turtle use different pathways to achieve anti-bacterial properties within their blood.
Devin Edmonds, who is a graduate student with Dr. Michael Dreslik at UI-UC and the Illinois Natural History Survey, examined Reproductive output of ornate box turtles (Terrapene ornate) in Illinois, USA. This is the first assessment of ornate box turtle reproduction in Illinois.
 
Meghan Garfinkel earned her PhD from University of Illinois-Chicago this spring. Her research quantified crop pest suppression by songbirds. She found Birds suppress pests in corn but release them in soybean crops within a mixed prairie/agriculture system. Additional data is needed to see if these results can be applied more broadly on the landscape and across years. These initial results indicate birds could provide sizable services to agricultural land around prairie habitat.
 
Physlis Pischl, a PhD student at Northern Illinois University, performed an elegant analysis of Plastome phylogenomics and phylogenetic diversity of endangered and threatened grassland species (Poaceae) in a North American tallgrass prairie. The work showed endangered and threatened grass species were more closely related than expected and likely evolved together in specific grassland habitats. Destruction of those habitats have resulted in many closely related species all being endangered and threatened. Read more about this study.

badgers
John Vanek shared his work with Dr. Rich King surveying snake communities at Nachusa in this recent blog. John also published Observations of American Badgers, Taxidea taxus (Schreber, 1777) (Mammalia, Carnivora), in a restored tallgrass prairie in Illinois, USA, with a new county record of successful reproduction. While it is no surprise to find badgers at Nachusa, this is a new confirmed report of breeding badgers.
 
Hana Thixton found Further evidence of Ceratobasidium serving as the ubiquitous fungal associate of Platanthera leucophaea (Orchidaceae) in the North American tallgrass prairie (open access) in her MSc research with Dr. Betsy Esselman at Southern Illinois University Edwardsville. Ceratobasidium fungi were by far the dominant fungal partner for EPFO, and genetic diversity of those strains was limited, indicating the fungal partners were consistent across sites.
 
Drew Scott found Plant diversity decreases potential nitrous oxide emissions from restored agricultural soil in this research as part of his PhD dissertation at Southern Illinois University Carbondale. In this study, he found nitrous oxide emissions, a potent greenhouse gas that contributes to climate change, from soils at Nachusa with high plant diversity were about seven times lower than from areas with low plant diversity.
