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

squirrels in a 100m by 100m area that respond to a hand-held
imitation ground squirrel call tool.
When cell death occurs due to ischemia or infarction then this is termed as Coagulative necrosis.
During this type of necrosis, cell death occurs in a localized area due to lack of oxygen and other nutrients.
When a two year old swallows watch batteries then these batteries becomes trapped in the digestive system and inside the digestive tract , the positive and negative terminals of the battery gets bridged by the mucosa leading to the production of the electrical current and increase in the pH of the mucosa.
All these condition leads to coagulative necrosis due to which the kidney gets affected and heart failure occurs .
