E NVIRONMENTAL D ISCOVERY C ENTER N EWS Nature in the heart of Florence County www.lynchesriverpark.com Hibernation vs. Torpor: Do Bears Really Sleep in the Woods? As we head into the colder months, we are beginning to see wildlife settling down for their long winter’s nap. Bears, squirrels and snakes all look for a nice quiet spot to sleep away the winter and not wake up until spring, right? Well, not exactly… First, what is “true hibernation?” Hibernation is defined as a state of inactivity in an animal brought about by shorter day lengths, colder temperatures and limitations of food. This inactivity can last for weeks or even months. Hibernation is a survival strategy that can be very successful in environments in which food is scarce or just difficult to find during a long, cold winter season. When an animal begins hibernation its body temperature drops very low, almost matching the outside temperature. The animal’s heartbeat and breathing slow down as well. Since they are using very E NVIRONMENTAL D ISCOVERY C ENTER N EWS J AN -M ARCH 2013 1110 Ben Gause little energy during this time, the animal is able to use the fat stored up during the Road fall, to live off of.

Torpor may be very short-term (the cold hours of the night, for example) and involves only a slight drop of the animal's body temperature to no less than about 60 °F.

An animal in in torpor is also capable of relatively quick arousal, waking up in times of warmer temperatures to search for food or to defecate. These animals may also store food in their caves and burrows to eat during times of arousal. They may walk around a little, and eat before going back to sleep. So which animals go through which process? True hibernators include bats, skunks, woodchucks (groundhogs), shrews, some snakes, some turtles and frogs and toads (in colder climates). A few animals that enter a torpid state are chipmunks, wild hamsters, nighthawks, door mice, polar, grizzly and black bears, badgers, and raccoons. Voles, red foxes, wild turkeys and grey squirrels are active throughout the year and don’t experience either process. In South Carolina, we do not have as many true hibernators as they do in the north because of a much milder climate. While there are a few significant differences between hibernation and torpor, both states allow an animal to use their body's energy reserves at a slower rate than they would if they were maintaining themselves at their typical basal metabolic rate. This could mean the difference between life and death for many animals. Photo of the Month Take Only Pictures, Leave Only Footprints The Environmental Discovery Center is looking for nature photographers of all levels to submit their best nature photos for the photo of the month contest. Every month, a photo will be featured on our Facebook page as well as in our quarterly newsletter. Submissions are open to anyone, any age, and any experience level. Your photo should be taken within Lynches River County Park and can feature any of the landscapes or wildlife. Please email all submissions to EDC@florenceco.org and include the following information: your name and your city and state of residence. Also, please remember to specify in your email that your photo is for the contest! Unselected photos are still under consideration for future months. Weekend Programs Are You Connected? Join us every Saturday and Sunday for live animal meet-andgreets! We’ll introduce you to one of our animals and allow you the opportunity to meet that animal up close. Animal presentations are every Saturday at 11:30am and 3:00pm and Sundays at 2:00pm Stay in the loop and learn the latest Environmental Discovery Center scoop!

The Eastern Box Turtle ranges throughout the southeast and north to Michigan and southern Massachusetts. Box turtles are highly variable in shell shape, pattern, and coloration. They are small-medium sized turtles, attaining a maximum length of about 8 inches. A key characteristic of box turtles is their hinged plastron (bottom shell) that can be shut completely to protect themselves from predators. Box turtles are amazingly versatile animals and inhabit a wide variety of habitats from wooded swamps to dry, grassy fields. And, although not aquatic, box turtles will often venture into shallow water at the edge of ponds or streams or in puddles. Box turtles are omnivores and will eat almost anything, animal or plant, that they can fit in their mouths. Interestingly, box turtles are even able to eat many mushrooms that are toxic to humans. Box turtles commonly reach 25-30 years of age and there are welldocumented cases of them living to 40 or even 50 years. Although box turtles are still fairly common over much of their range, their future is uncertain. The impact of taking turtles from the wild can be devastating to local populations. Over the span of their lifetime, female turtles will lay hundreds of eggs, but only 2-3 of these offspring will survive to adulthood. These offspring will eventually replace their elderly parents, allowing the population to remain at a stable size. But, if box turtles are removed from the overall breeding population (whether from being taken from the wild or being killed by human activities), the number of offspring drops, and the overall population declines. Additionally, box turtles have a homing instinct that causes them to try to return to the place of their birth if they are moved. As a result, when box turtles that have been taken as pets are returned to the wild, they will try to return to familiar areas. This journey causes the turtles to encounter many dangers, such as roads, predators, and humans. For these reasons, if you are looking for a pet, you should try to find a captive-bred animal or consider a different pet. Source: http://www.bio.davidson.edu/ Join the Fun: Volunteer!

Fun Facts Education Programs The environmental education dents with the costs associated programs offered at the EDC actively engage students in learning about nature and the environment and are correlated with South Carolina Science Academic Standards. Teachers are encouraged to bring their public, private and home school classes to the EDC to engage in standards-based activities, including an off-trail nature hike, that will further their knowledge of the natural world while they have fun outside the classroom. To see a list of programs offered, with traveling for field trips. please visit our website at Programs range from one to www.lynchesriverpark.com.
