Why Are Deer So Successful in Illinois?

By Jameson Mori and Nelda A. Rivera

There are many important factors related to the success of deer in Illinois, and deer habitat is one of them. In this article, the authors explain how measuring deer habitat can help answer this important question: Why are deer so successful in Illinois?.

“One look at this map will tell you that Illinois has a lot of deer habitat, and good deer habitat, too.”

Legend or Reality: Breaking the code of CWD myths

By Nelda A. Rivera and Nohra Mateus-Pinilla

“You may have heard about chronic wasting disease, or CWD, and wondered what causes it, who is affected, and what is happening to the white-tailed deer in Illinois. Here, we will decode CWD and discuss common and confusing myths about prion diseases, particularly CWD.”

New study finds Extension offices have vital role in fight against growing number of tick bites

By EMILY STEELE | Media Communications Manager

“Once uncommon in the Midwest, deer ticks, American dog ticks, lone star ticks, and others are now found across Illinois, and tick-borne diseases such as Lyme disease, Rocky Mountain spotted fever, anaplasmosis, and babesiosis are on the rise. Cases of alpha-gal syndrome, a red meat allergy, have also increased. Those who spend a lot of time outdoors, either for work or recreation, have a higher risk of being bitten.”

URBANA, Ill. — “A call, email, or visit to the local University of Illinois Extension office can help provide some peace of mind. New research from a multi-department team of university scientists explored the role Illinois Extension has in educating communities about ticks and preventing risky encounters.”

What is the Difference Between Tuberculosis, Paratuberculosis and Mycoplasmosis in Deer?

By Nelda A. Rivera and Nohra Mateus-Pinilla

“Learning to differentiate diseases affecting white-tailed deer (WTD) in Illinois can be challenging, as many pathogens — including bacteria, viruses, protozoa, and prions — could cause disease.”

Figure 1. Risk of bovine tuberculosis (bTB) transmission/spread at the cattle-human-wildlife interface5,6. Domestic and wild reservoir hosts (black), potential reservoir hosts (dark gray), and final hosts (light gray) can interact with each other and through the environment. Dash line show the potential indirect routes of infection between wildlife and humans.

Are you interested in knowing the difference between tuberculosis, paratuberculosis, and mycoplasmosis and how these diseases affect deer? Check the article in the Illinois Outdoor Journal here.

COVID-19 and wildlife: an interdisciplinary effort to disease surveillance in deer.

By Joey He | Undergraduate majoring in integrative biology at the University of Illinois at Urbana-Champaign.

COVID sampling team — we were cold but happy and thankful for the experience and the learning opportunity from hunters, IDNR and USDA biologists, and colleagues.

CHAMPAIGN, lL. – Joey He, an undergrad student member of the Wildlife Veterinary Epidemiology Laboratory (WVEL) at the Illinois Natural History Survey, narrates her experience participating in the collaborative effort of the WVEL along with the Illinois Department of Natural Resources (IDNR) and USDA-WS to collect COVID samples from hunter-harvested white-tailed deer.

CHAMPAIGN, lL. – Tick-borne illnesses like ehrlichiosis, Lyme disease and Rocky Mountain spotted fever are on the rise in Illinois, and outdoor workers like farmers are at higher risk than those who spend more time indoors. University of Illinois Urbana-Champaign Ph.D. candidate Sulagna Chakraborty and her colleagues at Illinois led a new study on the subject that surveyed 50 Illinois farmers to learn about their awareness of the problem and engagement in tick-prevention efforts. Chakraborty spoke to News Bureau life sciences editor Diana Yates about what they found.

CHAMPAIGN, IL – Understanding the role of diseases on reproduction is essential for safeguarding the reproductive health of wildlife populations. Furthermore, it enables informed decision-making, effective interventions, and targeted approaches to support reproductive health. In the article Impact of CWD on Fetal Growth and Pregnancy Rates in Illinois White-tailed Deer, Mori et al. summarize the latest research and their results related to the effect of CWD on Illinois white-tailed deer reproductive health.
