 An example of this is how the common house gecko can trigger an "avoidance response" in the Mourning Gecko, causing it to avoid a specific area where food may become available.Though triggering avoidance in other species, they themselves can tolerate the presence of other gecko species well, regardless of whether those species are smaller or larger, faster or slower, or more physically aggressive or not.This allows them greater access to feeding areas and territories, making them a highly successful invasive species.
