There are many ways to estimate ground squirrel numbers. The most common and popular monitoring technique is the combination of electronically recorded stress calls and visual counts where ground squirrels respond physically, vocally or both. You simply count the number of squirrels in a 100m by 100m area that respond to a hand-held imitation ground squirrel call tool.

There are numerous clues that confirm that these continents were once connected. Some of the clues are the matching cratons on the edges of the continents, the glacial deposits and scratches in the bedrock are also matching, lot of fossilized flora and fauna from the same species have been found in several of these continents, the marsupials in South America and Australia  etc.
