Describe the removal experiment done by (Brown et. al) to test for presumed predators.
|
3 species of rodent were living together:
Large granivore rodents (Kangaroo Rats) Small granivore rodents Insectivore rodents Brown et. al set up 24 enclosed pens and removed the kangaroo rats from most of the pens, leaving a few unchanged as control groups. In the pens with the kanagaroo rats removed, the population of small granivore rodents increased relative to the control group, while the insectivore population remained relatively unchanged. |
|
|
Define:
Aposematic |
Colored or constructed in a way that indicates special capabilities for defense.
|
|
|
Define:
Batesian Mimicry |
A form of mimicry typified by a situation where a harmless species has evolved to imitate the warning signals of a harmful species directed at a common predator.
