Tortoise Determines Sex...With Temperature
 
00:15
Sex determination in reptiles is much different than in mammals and birds. While genes are certainly still involved, the sex of many reptiles is determined by average incubation temperatures during critical periods of development. Global climate change could potentially skew sex ratios & threaten the survival of certain species.

Box Turtle and Russian Tortoise Outside Enclosure Update
 
08:36
I wanted to give my subscribers an opportunity to see my Russian Tortoise and box turtle Outside Enclosure. The enclosure lids keep any predators from coming in contact with my turtles. The plastic siding surrounding the outside perimeter of the enclosure completely eliminate the possibility of escape by climbing out of the enclosure. Box turtles have amazing wire climbing ability when they are determined to escape. Corners are another common escape attempt area if they can get just a little bit of grip. Plastic is completely slick and keeps them contained. Russian Tortoises also are excellent tunnelers so I have the siding clear down under the ground surface 16 inches down to the extremely hard dirt. I like the dandylions because they are excellent food sources for both russian and box turtles. Of course I supplement their food supply with various meats, carp eggs, fish filet, dry cat food and cracked oyster shell. They are in charge of scrounging for any insect , earth worm, slug or any other creepy thing that catches their eyes. In the video you can see the 5 gallon buckets that I have cut in half and made tunnels underneath them to provide shelter for them from sun and frost. I give a detailed look of the now completely empty hibernation chamber and the two tunnels that go from the enclosure to the area 30 inches or so underneath the surface. The turtles are doing a very great job of hiding today in the back of these shelter area. They have dug back farther than I can reach this year in several of them. Toby my baby box turtle born two years ago is doing fine this spring having survived his first outside winter hibernation. I understand that below zero hibernation over the winter can be hazardous to turtles, but on the other hand hibernation is completely natural for them to survive and successfully reproduce and live for decades. I will move my 4 baby box turtles that hatched last year 2014 out to the enclosure in a way the bigger ones will not hog all the food or shelter. I will probably not allow them to hibernate this winter outside and will bring them in. Of course I will be watching for box turtle egg laying again and will probably artificially incubate the eggs in a safer peat moss , proper humidity and temperture inside enironment. It is still quite frosty every morning here in Eastern Oregon so the only one really eating much is the Russian tortoise that has been out for a couple months on the half decent days. Box turtles and Russian tortoises are very interesting creatures but they require a commitment that appears to be a lot longer in years than raising children and possibly helping to raise grand children. I am concerned with my predeceasing them in 30 or 40 years and hope to have figured out a way to rehome them or at least some of them over the years. I hope you enjoy seeing the enclosure. If you have questions or any sort of comments just ask for my opinion.
