To determine how well the sea turtle hatchlings could perform after their walk on the treadmill, the hatchlings swam in a small tank using a specially designed swimsuit. Researchers measured oxygen consumption and lactate accumulation as well as their...
The researchers measured the length, width and height of moose skulls to study the impact of climate change on the iconic Northwoods species. The team measured 662 moose skulls and observed a 16 percent decrease in size over 40...
