Painted turtles, male, female, new research

Originally posted on Dear Kitty. Some blog: This 6 May 2018 video from the USA says about itself: In this video I will show you these cute amazing baby painted turtles. These baby turtles are only 1 day old and are so tiny, some of these baby turtles are the size of quarters and smaller. I saved the baby painted turtles from birds and at the end of the video I will let these turtles go. From Iowa State University in the USA: How scientists view sex determination in painted turtle populations August 6, 2019 Summary: A study that looks at how temperature influences the development of painted turtles may lead biologists to rethink the theoretical frameworks they use when analyzing the topic. The study found wide variation within local populations, suggesting temperature sensitivity of embryonic development can vary significantly from one turtle nest to another within a single population. A new study from Iowa State University scientists could flip the established framework for how scientists believe geography influences sex determination in painted turtles on its shell. The study, published Tuesday in the academic journal Functional Ecology, analyzed decades of data concerning painted turtles, a species widely distributed across North America that undergoes temperature-dependent sex determination. That means the temperatures experienced by an incubating painted turtle egg influence whether an embryo develops the physical characteristics biologists describe as male or female. Warmer temperatures tend to produce females, and cooler…

40,000 bluebirds housed in Idaho, USA

Originally posted on Dear Kitty. Some blog: This 25 July 2019 video from the USA says about itself: The Birdman of Idaho Has Built Homes for Over 40,000 Bluebirds He just might be the biggest bluebird landlord in Idaho. Al Larson has built and placed more than 350 wooden nest boxes throughout the state’s southwest. The birdwatcher started the project in the late 1970s after reading how important the shelters are to the survival of bluebirds. Today, at the age of 97, he is still at it. Larson monitors the little houses to record vital data about the number of eggs and nestlings. To date, Larson has helped fledge over 40,000 bluebirds.
