Which dispersal pattern, random uniform, or clumped, would cause the most problems for a random sampling approach?
In bluejay birds, the offspring may remain and assist the parents in rearing additional young because
a.there are no "costs" for being social
b.the offspring have no chance of obtaining a necessary territory otherwise
c.competition does not occur among these birds
d.predation rates are variable
e. predation influences bet-hedging in these long-lived birds
Uniform dispersion is when the individuals in a population is spaced more or less evenly. In clumped dispersion the individuals are clustered into groups as resources are less. Whereas in random dispersion the individuals are distributed randomly in a random fashion. This is the rarest form of dispersion in nature and hence this would cause the most problems for a random sampling approach.
Blue jay birds help their parents to rear additional young because option b) the offspring have no chance of obtaining a necessary territory otherwise. They are dependent on their parents for food and occasionally they are fed by their parents. Moreover blue jays are highly social birds and very closely attached to their family.
