Animal Colonies-Communities-Social Relationships

Question 1

Zooid Defined (know animal example)

Answer 1

colonial invertebrates, different organisms with different roles that comprise a super-organism (can’t live on their own). e.g. man-of-war, coral

Question 2

Eusocial Animals (3Major Characteristics)

Answer 2

cooperative care of young
non-fertile members support fertile members
there may be two or more generations overlapping in the same colony

Question 3

Haplodiploidy & Honeybees (eusocial)

Answer 3

Haplodiploidy creates predisposition for cooperative behavior.
Females develop from fertilized, diploid eggs, Males develop from unfertilized, haploid eggs.
Creates a predisposition for cooperative behavior because the sisters are closely related (kin selection)

Question 4

Diploid Sexes & Termites (eusocial)

Answer 4

Termites are all diploid, no matter the gender. But they are still eusocial, just not haplodiploid. Eusocial based on other factors (slow development, high risk dispersal, nest inheritance desirable, group defense of nest, food rich patches)

Question 5

Naked Mole Rat (major life history traits)

Answer 5

Eusocial. Large colonies. One fertile queen, polyandrous (One F, multiple Ms). Other Fs are sterile through suppression (pheromone in urine) and are workers. Cooperative care of young

Question 6

Conventional Parasitism Defined (animal example)

Answer 6

Parasite exploits food resources, feeds on host, often specializes in one host
e.g. ticks, leeches

Question 7

Parasitoidism Defined (animal example)

Answer 7

animal lays eggs in a host the eggs hatch out and larvae eats the host
e.g. some wasps (spider wasp?)

Question 8

Kleptoparasitism Defined (animal example)

Answer 8

One animal steals from another
e.g. satin bower bird steals ornaments to impress Fs, frigate bird steals food

Question 9

Social Parasitism Defined (animal example)

Answer 9

parasite gets its host to raise its young
e.g. cowbird

Question 10

Symbiotic Relationship Defined (animal example)

Answer 10

both individuals benefit (or one is neutral)
e.g. coral and algae
