The _______________ signifies that species richness is greater where two communities meet than at the center of either community. (a) edge effect (b) fundamental niche (c) character displacement (d) realized niche (e) limiting resource
A limiting resource does all the following except that it (a) tends to restrict the ecological niche of a species (b) is in short supply relative to a species need for it (c) limits the presence of a species in a given community (d) results in an intermediate disturbance (e) may be limiting for only part of an organisms life cycle
Although a species might be physiologically able to live under a wide range of resource conditions, competitors may restrict its use of resources in a particular location. This is known as a character displacement. b mutualism. c realized niche. d fundamental niche. e interference competition.
Which of the following defines the role of a species in a community,including its habitat and interaction with other species?a. ecological nicheb. competitive exclusionc. competition leveld. mimicrye. None of these are correctb
Disturbancescan alter a community’s stable environmental conditions, also called its:a.frequency.b.intensity.c.heterogeneity.d.equilibrium.e.niche space.
The average niche breadth for space resources is narrow for a community of intertidal organisms. This pattern would indicate… a. a fewer number of species in the community b. niche overlap is high c. resource partitioning d. high levels of disturbance e. extinction via competitive exclusion
The__________ defines the physical conditions under which a species might live, inthe absence of interaction with other species.a.functional nicheb.realized nichec.principle niched.fundamental nichee.primary niche
Which of the following statements best represents the productivityhypothesis regarding species richness?a. The larger the area, the greater the number of species that will befound there.b. Temperate regions have a lower species richness due to the lack oftime available for migration after the last Ice Age.c. The number of species in a particular community is directly relatedto the amount of available energy.d. As invertebrate productivity increases, species richness will increase.e. Species richness is not related to primary productivity.
Under what conditions can the realized niche of a species exceed its fundamental niche? a. never b. when the species is transported out of its natural geographic range c. when the species experiences mutualistic interactions with another species d. when the species is relieved of competition with another species e. all of the above (except for never)
When species occupy the same niche, they must compete with each other for limited resources. Check each outcome that is likely to occur in the long-term if two species occupy the same niche. (Select all that apply): O Exclusion of one species from the entire niche, but not the other. OExclusion of both species from the entire niche. Persistence of both species throughout the entire niche. O Division of the niche into two smaller niches, each dominated by a single species. Alternating cycles where one of two species is initially excluded but subsequently becomes dominant, excluding the other.
The "principle of tolerance limits".. relates species abundance and distribution to the physiological tolerance of the organism. defines the realized niche of an organism. can explain why more tolerant species face reduced risks of extinction. states that a species' tolerance to competition will limit the dispersion of individuals within a population.
Which of the following attributes of a community would tend to lead to higher species richness? High specialization of species A broad resource spectrum High population size in each species Both a and b Both b and c
