Chapter 44.2, Problem 1TYK
Summary Introduction
Introduction:
A community is a group of species existing in the similar habitat or having a particularly common feature. Community is also termed as a biological community. For example, soil containing

True or false? Grasslands are quick to develop into a climax community.
Which one of the following statements is FALSE?
Beta diversity is low when two ecosystems share the similar species and respective abundance.
An intelligent meander records date, time, location and a list of species.
Beta diversity or differentiation diversity compares alpha diversity among several communities.
Species richness is the total species abundance in an ecosystem.
Inventory diversity can be defined by alpha diversity, which is the number of species in a local forest stand.
In this class, we have discussed how populations form communities to create ecosystems and learn that comparing different communities could be done simply by determining species richness or species diversity. But to fully explore an ecosystem, we have to discuss the major components of its biodiversity. What are the major components of biodiversity and what is the importance of biodiversity?

- Some people think that our most environmental goals should be to sharply reduce the rate of population growth in the less-developed countries, where at least 92% of the world’s population is expected to take place between now and 2050. Others argue that the most serious environmental problems stem from high levels of resource consumption per person in more-developed countries, which have moreecological footprints per person. What is your view on this issue? Explain.arrow_forwardRabbits can eat many plants, but they prefer some plants over others. Assume that the rabbits in a grassland community containing many plant species prefer to eat a species of grass that happens to be a superior competitor. If the rabbits are removed from the region, predict whether relative species abundance will increase or decrease, and whether species richess will increase or decrease.arrow_forwardThe model of metapopulations also postulates that many species occupy their patches only temporarily, that sooner or later they will be eliminated by competition or some other factor. If this is true, would such a patch make a suitable wildlife preserve for that species? Discuss what wildlife managers might have to do with such a preserve.arrow_forward
- a population of mice moves into a field in which secondary succession is occurring. What is the most likely reason the mouse population moved into this area?arrow_forwardThe smallest population of a species that is likely to be able to survive in the long term is called the_________ . When suitable habitat for a given species is split up into areas that are too small to support a large enough population, this is called_______ . One way to maintain large enough populations is to set up core reserves of suitable habitat, connected by_______ .arrow_forwardThe _______________ 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 resourcearrow_forward
- Predation, disease, and competition are examples of _______________ factors. (a) density-dependent (b) density-independent (c) survivorship (d) dispersal (e) semelparousarrow_forwardWhich of the following statements about the concept of ecological niche is correct? A species' realized niche, may or may not be the same as its fundamental niche The fundamental niche of a species includes biotic and abiotic factors while the realized niche only includes biotic factors A species' fundamental niche is always smaller than its realized niche A niche is the same as a habitatarrow_forwardNow think about the diversity index you calculated in the diversity and succession labs: a value calculated of 10 in Habitat A and 5 in Habitat B would indicate: Habitat A likely has higher species richness and lower species evenness than Habitat B Habitat A likely has lower species richness and lower species evenness than Habitat B Habitat A likely has higher species richness and higher species evenness than Habitat B Habitat A likely has higher species richness and the same species evenness as Habitat Barrow_forward
- 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 ratesarrow_forwardCommunity - Competition. Competition between species on the same trophic tier leads to four potential outcomes, 3 are deterministic (zero sum games where one species goes extinct and the other maximizes their growth to balance at the carrying capacity) and one where both competitors survive, but neither does well. This dynamic suggests that extirpation (local extinction) of populations is a far more likely outcome than co-existence. How, in your opinion, does this affect management policies aimed at increasing biodiversity and proliferation of inter and intra population and interspecies variation. Reason your point of view. Endangered species are defined by low growth rates (r ) and low K (reflecting high demand for resources). What are the implications of both these factors on the outcome of competition scenarios, especially the most common scenario of alternate stable states?arrow_forwardWhich of the following might you expect if you increase the amount of energy (and nutrients) into an ecosystem? Group of answer choices increase rates of competition among species increase the consumption of fossil fuels increase the number of trophic levels decrease the standing croparrow_forward
