Population Decline of Ground Squirrels, Spermophilus (Rodentia, Sciuridae), in Ukraine and Forecasting Trends
Population trends of ground squirrels (Spermophilus citellus, S. suslicus and S. pygmaeus) in Ukraine were assessed using census data from the Plant Protection Inspection Service (1937–2007). Comparing these data with observations from the first decades of the 21st century suggests that ground squir...
