Mark recapture techniques -
Zach was introduced to the process of studying how environmental changes affect a population. The first step is to determine the size of the populations. This is difficult for wild animals and often requires a mark capture recapture process. This involves marking a few individuals before releasing them back to the wild. You recapture a subset of the larger group and measure how many have the original mark. There are many various issues with this process based on some assumptions on specific characteristics of the population. We examined the various assumptions and how they affect the process. He examined some studies where this process is used and some where the process is not suitable.
