Which factor might have favored the evolution of semelparity over iteroparity in different
species of salmon?
-Breeding significantly decreases parental survival rates.
-There are few opportunities for successful breeding.
, -Synchronous breeding overwhelms predators.
-The chance of dying before breeding increases with age. correct answers -Breeding significantly
decreases parental survival rates.
Tropical bird species tend to produce smaller clutches of eggs than temperate bird species. One
hypothesis put forward to explain the difference in clutch size is that the time available for
gathering food differs between tropical and temperate species. Another hypothesis is that tropical
and temperate species have different strategies that affect the quality and overall robustness of
individual nestlings.
Match each piece of evidence with the hypothesis that it supports:
Temperate bird species make more foraging trips per day than tropical bird species. correct
answers Food-gathering time influences clutch size.

and temperate species have different strategies that affect the quality and overall robustness of

Match each piece of evidence with the hypothesis that it supports:
Tropical bird species do not gather food at a faster rate than temperate bird species. correct
answers Food-gathering time influences clutch size.

hypothesis put forward to explain the difference in clutch size is that the time available for
gathering food differs between tropical and temperate species. Another hypothesis is that tropical
and temperate species have different strategies that affect the quality and overall robustness of
individual nestlings.
Match each piece of evidence with the hypothesis that it supports:
Bird species from both regions can usually at least provide enough food to keep the nestlings in
their clutch from starving. correct answers Food-gathering time influences clutch size.
