The most important factor for the outcome of a reintroduction attempt is whether it is a producer or consumer species. After this the most important factor if you reintroduce a producer-species is how much change it has in its attributes from captivity. However if a consumer species was reintroduced the change in its attributes was not the most important factor, they were more sensitive to the change that occurred in the food-web after they were removed from it, hence the Euclidian distance is the most important factor (change in there attributes comes after that).

The removal and later reintroduction of producer species affects the food web the most out of the three trophic levels.
