A recent United Nations analysis report gathered data on declines in biodiversity across the world. Using the graphs provided, which statement shows an area of concern and is an alternative to the general hypothesis "Humans are responsible for a significant increase in the extinction rate among species in the world today as a result of damage caused to the environment"?
A. Fertilizer use in developing countries should be encouraged to decrease the extinction rate
B. Decreasing air pollution in the least developed countries would decrease species survival rate
C. Protection of key biodiversity areas should be a priority for developed countries to lower the extinction rate
D. Assisting developing countries with more sustainable methods of extraction of living biomass would increase species survival rates
In a tropical rainforest, an open gap lacking vegetation has been created by the fall of a large tree. Which of the following statements describes the characteristics of the plant species that are last to colonize this disturbed habitat?
a.
they have low reproductive rates and are good competitors
b.
they are good colonizers
c.
they have high reproductive rates and are poor competitors
d.
they are dominated by r-selected species
e.
they have high species diversity
Which statement about zero population growth isoclines of two competing species is true?
A.
Species coexistence requires that the two isoclines cross.
B.
The crossing of the two isoclines is a sufficient condition for species coexistence.
C.
If the species coexist, they will each do so at a higher density than either would if placed alone.
D.
Strongly competing species can only coexist if the two species have very different carrying capacities.
E.
Coexistence will occur if the two isoclines are parallel.

- slands are well known for having many endemic (unique) species. What is a likely explanation for this pattern? A. Humans bring partly or fully domesticated species with them when they arrive on islands. B. Colonizers encounter fewer competitors on an island, so they can diversify. C. Islands are more complex habitats than continents are, so they have more niches for specializations. D. Colonizers are likely to have more diversity than local populations and thus outcompete them. E. The type of organism that is a good colonizer has more than the average amount of genetic variability, so it's more likely to speciate.arrow_forwardWhich of the following is not true of a population of largepredators in a small reserve?a.

- According to the competitive exclusion principle, two species cannot exist together if they occupy the same niche. Either they diverge their niches so they can coexist or one species will die out.All of the following are consistent with the principle of competitive exclusion EXCEPT Select one: a. Birds and bats both consume flying insects, but birds are active in the day and bats are active at night. b. Two species that share the same niche will exclude other competing species. c. Different bird species forage for insects in different parts of the same tree. d. When two species of Paramecium are grown in the same medium, one strain will eventually eliminate its competitor.arrow_forwardSpatial scales are interconnected in a hierarchical way. Whitman looked at invertebrate communities on subtidal rock walls to examine the relationship between local and regional species richness. His studies demonstrated that A. local, not regional, processes determine local community species diversity B. local species richness levels off at high regional species richness levels C. local species richness is determined largely, but not completely, by regional species pools D. local processes are unimportant in determine local community species diversity E. There was no relationship between local and regional species richnessarrow_forwardThe long-leaf pine forest ecosystem once extended across 95 million acres of the southeastern US.
