Description

Previously you observed the following:

ODragonflies prey on insects, but they only very rarely eat butterflies-

OGoldfinches eat butterflies in large numbers-

OHawks prey on a small species of birds that are similar to the birds that eat
butterflies-

oThe new plant species is similar to the plants that the butterflies eat, but there are no
consumers that eat those plants in the meadow-

oThis viral strain kills a species of snail that lives in the butterfly habitat and eats the
same plants as the butterflies-

Based on you previous observations, formulate a hypothesis on what the impact of
one environmental factor would be- Why do you think this hypothesis might be
correct? Keep in mind that any hypothesis that is testable is a good hypothesis- Even
if you hypothesis is proven wrong, you will know more about butterfly populations
than you did before! Write you hypothesis in you lab notes-

Ohoose another species or the viral strain, and write a second hypothesis about how
this new introduction, made independently of the first one, would impact trait
frequency-
