When measuring the weight of individuals in a population of ground squirrels, what tools would be most appropriate

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.

I hope this helps, Regards.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
