TPO32-3 Distributions of Tropical Bee Colonies
1. The word “rival” in the passage is closest in meaning to
A established peting C nearby D different
2. According to paragraph 2, some species of stingless bees are aggressive mainly toward
A nonaggressive bees that forage on the same flowers B aggressive bees of other species C bees from their own colony D bees of their own species from different colonies
A
3. According to paragraph 3, Hubbell and Johnson hypothesized that
A the distribution pattern of bee colonies determines the degree of aggressiveness the bees display B nests of nonaggressive bees have either a random or a clumped distribution, while nests of aggressive bees have a regular distribution
C nests of nonaggressive bees are generally both closer together and more regularly distributed than those of aggressive bees
D nests of aggressive bees tend to be more regular in shape than those of nonaggressive bees
In 1977 ecologists Stephen Hubbell and Leslie Johnson recorded a dramatic example of how social interactions can produce and enforce regular spacing in a population. They petition and nest spacing in populations of
stingless bees in tropical dry forests in Costa Rica. Though these bees do no sting, rival colonies of some species fight fiercely over potential nesting sites.
Stingless bees are abundant in tr
