Yellow-eyed salamanders have been cited as an example of Batesian mimicry; their orange body color and yellow eyes mimic the coloration of the toxic California newt. Although the salamanders are palatable, their mimicry of a unpalatable species tends to prevent predators from attacking. In a follow-up study, Kuchta et al. observed the reaction of Western scrub jays (predators with toxic newt experience) when presented with both a yellow-eyed salamander and a closely related species after being presented with a toxic newt. What was significant about this study

It was a follow-up controlled experiment that showed how a species can influence selection in another species.

Explanation:

A follow-up (cohort) study is a type of study followed over time in order to determine the development of a particular outcome. Moreover, a controlled experiment is one in which conditions are controlled by the researcher, and thereby it is easier to determine the incidence of the outcome. In the case above described, researchers performed a follow-up controlled experiment in which they measured how a species can influence selective processes undergone by other species.
