Which
of the following animals would you not expect to be highly poisonous?
a snake with red and black bands
a butterfly with orange and black wings
a pale green caterpillar
a red and black grasshopper

What
type of populations would be most likely to show resource partitioning?
sympatric populations of species with
similar ecological niches
sympatric populations of a predator and its
prey
allopatric populations of the same animal
species
allopatric populations of a flowering plant
and its specialized insect pollinator

A
group of long-billed prairie birds migrates from a pristine, protected prairie
to a nearby, newly restored prairie. They colonize and establish a breeding
population in the restored prairie. Years later, scientists compare the two
bird populations and find that long-billed prairie birds in the newly colonized
area consume a much smaller range of food types than birds from the original
population, even though food availability is similar in the two areas. What
might be an explanation for this?
The two populations of the long-billed
prairie-birds had different fundamental niches, but the same realized niche
The original population of long-billed
prairie-birds had higher levels of competition for food resources and in order
to find enough food had a more varied diet. Those in the newly colonized area
faced less competition and adapted to a smaller range of food types.
While the long-billed prairie-bird’s
fundamental niche included a wide range of prey species, competition with other
species in the newly colonized prairie reduced the realized niche such that
fewer food types were utilized
The long-billed prairie-bird’s fundamental
niche shifted as a result of competition with other species such that
individuals in the newly colonized prairie foraged on a smaller variety of food
types

The
ideal biotic and abiotic environment a species can inhabit is referred to as
the ________, while the ________refers to the environment that an animal
actually inhabits after accounting for interactions with other species.
ideal niche; realized niche
fundamental niche; realized niche
fundamental niche; ecological niche
realized niche; fundamental niche

Milkweed
plants contain cardiac glycosides, substances that are toxic to many species.
However, the caterpillars of the monarch butterfly have evolved to feed on
milkweed, and are thus able to tolerate the toxins and even sequester them for
protection from predators. Milkweed also produces a sticky substance called
latex, which can entrap and kill small monarch caterpillars. It has recently
been discovered that monarch caterpillars often nibble through a leaf’s petiole
(attachment point) before feeding on the leaf – this cuts off the supply of
latex to the leaf. If you could travel far into the future, what development do
you think you would be most likely to find in the milkweed/monarch interaction?
Monarchs have evolved to tolerate ingestion
of latex and no longer chew through leaf petioles prior to feeding
Milkweed plants have evolved to have
tougher petioles; most monarchs are unable to chew through them prior to
feeding on leaves.
Monarch have switched from feeding on
milkweed to feeding on oak leaves.
Milkweed plants have stopped producing
cardiac glycosides, allowing other species besides monarchs to feed on them.
You are studying the feeding habits of a group of four closely
related bird species. You observe that all four species feed on insects.
However,you notice that the species do not feed at the same time of day: one
species feeds most actively at dawn, another during the middle of the day,
another at dusk, and the last species feeds at night. What term would you use
to describe this behavior?
competitive exclusion
interference competition
resource partitioning
exploitation competition
