Parasite and Host Data Analysis

APBIO-Z2FP4K

Moskat and Honza (2000) studied the interrelationship between the cuckoo (parasite) and Great Reed warbler (host). In their research, ninety nesting sites were observed. Thirty-one nests (34%) went un-parasitized, thirty-seven nests (41%) were parasitized only once, and twenty-two nests (24%) were parasitized numerous times.

Statistically speaking, the differences observed between the single- and multiple-parasitized nests were weakly significant and attributed to chance alone.

Which of the following factors BEST explains these data?

A

Parasitized nests were situated farther from cuckoo perch sites compared with un-parasitized nests.

B

Parasitized nests were much more visible from cuckoo perch sites compared with un-parasitized nests.

C

Parasitized nests were situated closer to each other compared with un-parasitized nests.

D

Parasitized nests were much smaller in size compared with un-parasitized nests.
