Cat owners want Kitty to be happy, but providing an abundance of food and snacks can have unintended consequences. Feline obesity is on the rise, impacting the health, longevity, and wellbeing of cats.

Bats come out of the shadows during Bat Week (Oct. 24-31, 2023), an international awareness campaign that aims to educate the public about bat conservation in the week leading up to Halloween.

URBANA, Ill. — For University of Illinois Urbana-Champaign sophomore Joe Del Rio, getting up close and personal with South America’s wildlife this summer was a dream come true.

URBANA, Ill. — Artificial roosts for bats come in many forms — bat boxes, condos, bark mimics, clay roosts, and cinder block structures, to name a few — but a new conservation practice and policy article from researchers at the University of Illinois Urbana-Champaign<

URBANA, Ill. – Rivers split across mountaintops and other geographic barriers may flow only a few miles from one another, but to the aquatic creatures in those waters, the separation could represent millions of years of evolutionary time. So, when an angler or a curious child moves a fish from one side of the mountain or one side of the country to the other, it’s a very big deal to the fish. Some may discover a competitive advantage in a new stream, potentially disrupting eons-old ecological hierarchies.

URBANA, Ill. – How do we bring threatened and endangered animals back from the brink? The task is never easy or simple, but one thing is undeniably true: If we don’t understand these animals and what they need to survive, we have little chance of success.

Saving bats, then, is arguably a trickier endeavor than for other species. After all, the cryptic critters only emerge at night and are highly mobile, making it difficult to track their movements and behavior.

URBANA, Ill. – Imagine if you had to catch every bite of your dinner with your mouth, while flying, in the dark. You’d be exhausted, and probably pretty hungry. Though some bats go for sedentary insects, most catch their food on the wing every single night. Let that sink in.

URBANA, Ill. – Deep in a Panamanian rain forest, bird populations have been quietly declining for 44 years. A new University of Illinois-led study shows a whopping 70% of understory bird species declined in the forest between 1977 and 2020. And the vast majority of those are down by half or more.

CHAMPAIGN, Ill. — A study of overweight dogs fed a reduced calorie, high-protein, high-fiber diet for 24 weeks found that the dogs’ body composition and inflammatory markers changed over time in ways that parallel the positive changes seen in humans on similar diets. The dogs achieved a healthier weight without losing too much muscle mass, and their serum triglycerides, insulin and inflammatory markers all decreased with weight loss.

URBANA, Ill. – China’s Père David’s deer was nearly gone in the late 1800s. Just 18 deer – the very last of their kind – were brought into captivity after the rest had been hunted to extinction. When 11 of the deer reproduced, the species had a chance. Today, after centuries of reintroductions and breeding under human care, the population sits at around 3,000.
