I looked up the ecological niche/purpose of the tick. SERIOUSLY, this is its only purpose??? An indicator? Ecologists often use ticks and other parasites as an indicator of an ecosystems health. Because ticks rely on a variety of host animals (mice, rats, deer, etc.) to thrive and reproduce, ecologists study tick population, distribution and health to understand ecological trends better. For example, if an ecologist finds that tick populations have dropped considerably in a specific area for more than the past 10 years, he would also expect to find a drop in the population or health of available host species, indicating a deteriorating ecosystem. In contrast, when an ecologist finds tick populations on the rise, it would suggest that healthier host species are available, indicating a healthy ecosystem.
