rate of increase
measurement parameters
census
index of population size
previous

Explanation:

To determine the correct method for measuring populations using animal signs (droppings, tracks, nests), we analyze each option:

• "Rate of increase" measures population growth over time, not signs.
• "Measurement parameters" is a general term, not specific to sign - based population measurement.
• "Census" involves counting every individual, which is not feasible via signs.
• "Index of population size" uses indirect signs (e.g., droppings, tracks) to estimate population size, matching the description.

Answer:

Index of population size
