Question
The upward incorporation theory of this concept in roundworms suggests that it evolved to take advantage of predators, whereas downward incorporation saw the parasite first evolve to survive independently of its host. For 10 points each:
[10e] Name this concept represented by haplodiplontic “alternation of generations” in plants. In insects, circular diagrams of this concept depict their maturation as they go through egg, nymph, pupa, and imago stages.
ANSWER: biological life cycle [accept life history]
[10h] Periodic life cycle events like migration and pollination which rely on the interaction of different species may become unsynchronized, according to this field’s mismatch theory. This biological field studies how outside factors, like climate change, can impact seasonal cycles.
ANSWER: phenology [accept phenological mismatch]
[10m] In an example of phenological mismatch, the snowshoe hare’s white coat is delayed, leaving it vulnerable to these specialist predators. Habitat loss has decimated populations of the endangered Iberian species of these animals.
ANSWER: lynx [accept Canada lynx or Iberian lynx or European lynx; accept bobcat]
