托福閱讀真題:TPO11原文
Ancient Egyptian Sculpture
In order to understand ancient Egyptian art, it is vital to know as much as possible of the elite Egyptians' view of the world and the functions and contexts of the art produced for them. Without this knowledge we can appreciate only the formal content of Egyptian art, and we will fail to understand why it was produced or the concepts that shaped it and caused it to adopt its distinctive forms. In fact, a lack of understanding concerning the purposes of Egyptian art has often led it to be compared unfavorably with the art of other cultures: Why did the Egyptians not develop sculpture in which the body turned and twisted through space like classical Greek statuary? Why do the artists seem to get left and right confused? And why did they not discover the geometric perspective as European artists did in the Renaissance? The answer to such questions has nothing to do with a lack of skill or imagination on the part of Egyptian artists and everything to do with the purposes for which they were producing their art.
The majority of three-dimensional representations, whether standing, seated, or kneeling, exhibit what is called frontality: they face straight ahead, neither twisting nor turning. When such statues are viewed in isolation, out of their original context and without knowledge of their function, it is easy to criticize them for their rigid attitudes that remained unchanged for three thousand years. Frontality is, however, directly related to the functions of Egyptian statuary and the contexts in which the statues were set up. Statues were created not for their decorative effect but to play a primary role in the cults of the gods, the king, and the dead. They were designed to be put in places where these beings could manifest themselves in order to be the recipients of ritual actions. Thus it made sense to show the statue looking ahead at what was happening in front of it, so that the living performer of the ritual could interact with the divine or deceased recipient. Very often such statues were enclosed in rectangular shrines or wall niches whose only opening was at the front, making it natural for the statue to display frontality. Other statues were designed to be placed within an architectural setting, for instance, in front of the monumental entrance gateways to temples known as pylons, or in pillared courts, where they would be placed against or between pillars: their frontality worked perfectly within the architectural context.
Statues were normally made of stone, wood, or metal. Stone statues were worked from single rectangular blocks of material and retained the compactness of the original shape. The stone between the arms and the body and between the legs in standing figures or the legs and the seat in seated ones was not normally cut away. From a practical aspect this protected the figures against breakage and psychologically gives the images a sense of strength and power, usually enhanced by a supporting back pillar. By contrast, wooden statues were carved from several pieces of wood that were pegged together to form the finished work, and metal statues were either made by wrapping sheet metal around a wooden core or cast by the lost wax process. The arms could be held away from the body and carry separate items in their hands; there is no back pillar. The effect is altogether lighter and freer than that achieved in stone, but because both perform the same function, formal wooden and metal statues still display frontality.
Apart from statues representing deities, kings, and named members of the elite that can be called formal, there is another group of three-dimensional representations that depicts generic figures, frequently servants, from the nonelite population. The function of these is quite different. Many are made to be put in the tombs of the elite in order to serve the tomb owners in the afterlife. Unlike formal statues that are limited to static poses of standing, sitting, and kneeling, these figures depict a wide range of actions, such as grinding grain, baking bread, producing pots, and making music, and they are shown in appropriate poses, bending and squatting as they carry out their tasks.

Timberline Vegetation on Mountains
The transition from forest to treeless tundra on a mountain slope is often a dramatic one. Within a vertical distance of just a few tens of meters, trees disappear as a life-form and are replaced by low shrubs, herbs, and grasses. This rapid zone of transition is called the upper timberline or tree line. In many semiarid areas there is also a lower timberline where the forest passes into steppe or desert at its lower edge, usually because of a lack of moisture.
The upper timberline, like the snow line, is highest in the tropics and lowest in the Polar Regions. It ranges from sea level in the Polar Regions to 4,500 meters in the dry subtropics and 3,500-4,500 meters in the moist tropics. Timberline trees are normally evergreens, suggesting that these have some advantage over deciduous trees (those that lose their leaves) in the extreme environments of the upper timberline. There are some areas, however, where broadleaf deciduous trees form the timberline. Species of birch, for example, may occur at the timberline in parts of the Himalayas.
At the upper timberline the trees begin to become twisted and deformed. This is particularly true for trees in the middle and upper latitudes, which tend to attain greater heights on ridges, whereas in the tropics the trees reach their greater heights in the valleys. This is because middle- and upper- latitude timberlines are strongly influenced by the duration and depth of the snow cover. As the snow is deeper and lasts longer in the valleys, trees tend to attain greater heights on the ridges, even though they are more exposed to high-velocity winds and poor, thin soils there. In the tropics, the valleys appear to be more favorable because they are less prone to dry out, they have less frost, and they have deeper soils.
There is still no universally agreed-on explanation for why there should be such a dramatic cessation of tree growth at the upper timberline. Various environmental factors may play a role. Too much snow, for example, can smother trees, and avalanches and snow creep can damage or destroy them. Late-lying snow reduces the effective growing season to the point where seedlings cannot establish themselves. Wind velocity also increases with altitude and may cause serious stress for trees, as is made evident by the deformed shapes at high altitudes. Some scientists have proposed that the presence of increasing levels of ultraviolet light with elevation may play a role, while browsing and grazing animals like the ibex may be another contributing factor. Probably the most important environmental factor is temperature, for if the growing season is too short and temperatures are too low, tree shoots and buds cannot mature sufficiently to survive the winter months.
Above the tree line there is a zone that is generally called alpine tundra. Immediately adjacent to the timberline, the tundra consists of a fairly complete cover of low-lying shrubs, herbs, and grasses, while higher up the number and diversity of species decrease until there is much bare ground with occasional mosses and lichens and some prostrate cushion plants. Some plants can even survive in favorable microhabitats above the snow line. The highest plants in the world occur at around 6,100 meters on Makalu in the Himalayas. At this great height, rocks, warmed by the sun, melt small snowdrifts.
The most striking characteristic of the plants of the alpine zone is their low growth form. This enables them to avoid the worst rigors of high winds and permits them to make use of the higher temperatures immediately adjacent to the ground surface. In an area where low temperatures are limiting to life, the importance of the additional heat near the surface is crucial. The low growth form can also permit the plants to take advantage of the insulation provided by a winter snow cover. In the equatorial mountains the low growth form is less prevalent.
Paragraph 1: The transition from forest to treeless tundra on a mountain slope is often adramatic one. Within a vertical distance of just a few tens of meters, trees disappear as a life-form and are replaced by low shrubs, herbs, and grasses. This rapid zone of transition is called the upper timberline or tree line. In many semiarid areas there is also a lower timberline where the forest passes into steppe or desert at its lower edge, usually because of a lack of moisture.

2. Where is the lower timberline mentioned in paragraph 1 likely to be found?
○In an area that has little water
○In an area that has little sunlight
○Above a transition area
○On a mountain that has on upper timberline.
3. Which of the following can be inferred from paragraph 1 about both the upper and lower timberlines?
○B(yǎng)oth are treeless zones.
○B(yǎng)oth mark forest boundaries.
○B(yǎng)oth are surrounded by desert areas.
○B(yǎng)oth suffer from a lack of moisture.
Paragraph 2: The upper timberline, like the snow line, is highest in the tropics and lowest in the Polar Regions. It ranges from sea level in the Polar Regions to 4,500 meters in the dry subtropics and 3,500-4,500 meters in the moist tropics.

There are some areas, however, where broadleaf deciduous trees form the timberline. Species of birch, for example, may occur at the timberline in parts of the Himalayas.
4. Paragraph 2 supports which of the following statements about deciduous trees?
○They cannot grow in cold climates.
○They do not exist at the upper timberline.
○They are less likely than evergreens to survive at the upper timberline.
○They do not require as much moisture as evergreens do.
Paragraph 3: At the upper timberline the trees begin to become twisted and deformed. This is particularly true for trees in the middle and upper latitudes, which tend to attain greater heights on ridges, whereas in the tropics the trees reach their greater heights in the valleys. This is because middle- and upper- latitude timberlines are strongly influenced by the duration and depth of the snow cover. As the snow is deeper and lasts longer in the valleys, trees tend to attain greater heights on the ridges, even though they are more exposed to high-velocity winds and poor, thin soils there. In the tropics, the valleys appear to be more favorable because they are less prone to dry out, they have less frost, and they have deeper soils.
5. The word "attain" in the passage is closest in meaning to
○require
○resist
○achieve
○endure
6. The word "they" in the passage refers to
○valleys
○trees
○heights
○ridges
7. The word "prone" in the passage is closest in meaning to

8. According to paragraph 3, which of the following is true of trees in the middle and upper latitudes?
○Tree growth is negatively affected by the snow cover in valleys
○Tree growth is greater in valleys than on ridges.
○Tree growth on ridges is not affected by high-velocity winds.
○Tree growth lasts longer in those latitudes than it does in the tropics.
Paragraph 4：There is still no universally agreed-on explanation for why there should be such a dramatic cessation of tree growth at the upper timberline. Various environmental factors may play a role. Too much snow, for example, can smother trees, and avalanches and snow creep can damage or destroy them.

Probably the most important environmental factor is temperature, for if the growing season is too short and temperatures are too low, tree shoots and buds cannot mature sufficiently to survive the winter months.
9. Which of the sentences below best express the essential information in the highlighted sentence in the passage? In correct choices change the meaning in important ways or leave out essential information.
○B(yǎng)ecause of their deformed shapes at high altitudes, trees are not likely to be seriously harmed by the strong winds typical of those altitudes.
○As altitude increases, the velocity of winds increase, leading to a serious decrease in the number of trees found at high altitudes.
○The deformed shapes of trees at high altitudes show that wind velocity, which increase with altitude, can cause serious hardship for trees.
○Increased wind velocity at high altitudes deforms the shapes of trees, and this may cause serious stress for trees.
10. In paragraph 4, what is the author's main purpose in the discussion of the dramatic cessation of tree growth at the upper timberline?
○To argue that none of several environment factors that are believed to contribute to that phenomenon do in fact play a role in causing it.
○To argue in support of one particular explanation of that phenomenon against several competing explanations
○To explain why the primary environmental factor responsible for that phenomenon has not yet been identified
○To present several environmental factors that may contribute to a satisfactory explanation of that phenomenon
Paragraph 6: The most striking characteristic of the plants of the alpine zone is their low growth form. This enables them to avoid the worst rigors of high winds and permits them to make use of the higher temperatures immediately adjacent to the ground surface. In an area where low temperatures are limiting to life, the importance of the additional heat near the surface is crucial. The low growth form can also permit the plants to take advantage of the insulation provided by a winter snow cover. In the equatorial mountains the low growth form is lessprevalent.
11. The word "prevalent" in the passage is closest in meaning to
○predictable
○widespread
○successful
○developed
12. According to paragraph 6, all of the following statements are true of plants in the alpine zone EXCEPT:
○B(yǎng)ecause they are low, they are less exposed to strong winds.
○B(yǎng)ecause they are low, the winter snow cover gives them more protection from the extreme cold.
○In the equatorial mountains, they tend to be lower than in mountains elsewhere.
○Their low growth form keeps them closer to the ground, where there is more heat than further up.
Paragraph 5: Above the tree line there is a zone that is generally called alpine tundra. █Immediately adjacent to the timberline, the tundra consists of a fairly complete cover of low-lying shrubs, herbs, and grasses, while higher up the number and diversity of species decrease until there is much bare ground with occasional mosses and lichens and some prostrate cushion plants. █Some plants can even survive in favorable microhabitats above the snow line.

山上樹帶界線的植被
通常從山坡上的森林到?jīng)]有樹的苔原是一種非常戲劇化的轉變。在一個垂直距離只有幾十米的地方，樹木這種生命形式就消失了，取而代之的是低矮的灌木、草本植物和牧草。這種快速過渡的區(qū)域被稱為上行樹帶界線或林木線。在許多干旱的地區(qū)存在著下行樹帶界線，在這里由于缺乏水分森林變成干草原，甚至在最下端會出現(xiàn)沙漠。
上行樹帶界線，和雪線一樣，在熱帶最高，在極地最低。從極地地區(qū)的海平面到干燥的亞熱帶地區(qū)的海拔4 500米處以及潮濕的熱帶地區(qū)海拔3 500米至4 500米處都有上行樹帶界線。樹帶界線內通常是常綠樹，它們和處于上行樹帶界線處極端惡劣環(huán)境中生長的落葉樹木相比，具有一定的優(yōu)勢。然而，在部分地區(qū)也有由落葉闊葉林組成的樹帶界線。例如，在喜馬拉雅的部分地區(qū)，樺樹就在樹帶界線上。
上行樹帶界線的樹木開始扭曲和變形，尤其在中高緯度地區(qū)的樹木，這些地區(qū)的樹木往往會在山脊上長得更高，而在熱帶地區(qū)的樹木則在山谷里長得更高;因為中高緯度地區(qū)樹帶界線受積雪覆蓋時間和深度的影響很大。由于山谷中積雪覆蓋較厚且持續(xù)時間很長，樹木即便是生長在大風和貧瘠的土地里，也往往會在山脊上長得更高。在熱帶地區(qū)山谷里更有利于生長，因為山谷不易干涸、很少結霜，并且有更深的土壤。
目前還沒有一個普遍認同的解釋來說明為什么會在樹帶界線上出現(xiàn)樹木停止生長這種戲劇化的現(xiàn)象。多種環(huán)境因素都起到作用，例如，積雪過多會讓樹木透不過氣，雪崩和雪移能摧毀樹木;長時間積雪縮短了有效生長季節(jié)的時間，樹苗無法生長;另外，風速會隨著海拔的升高而增加，增加樹木承受的壓力，很明顯，正是這種風速帶來的壓力導致樹木在高緯度地區(qū)發(fā)生變形。一些科學家提出，隨著海拔的上升而不斷增強的紫外線、野生山羊等動物的放養(yǎng)，都是導致樹帶界線形成的因素?；蛟S最重要的環(huán)境因素是溫度，因為如果生長季節(jié)太短并且氣溫太低，樹芽和樹苗都無法充分地成長而存活過冬季。
在林木線之上有一個稱為高山苔原的地帶。由于緊挨著樹帶界線，苔原上都是矮灌木、草本植物和牧草。隨著海拔的增加，物種的數(shù)量和多樣性會逐漸減少，直到出現(xiàn)大量空地伴著零星的苔蘚和地衣這樣的伏地墊狀植物。有些植物甚至可以在雪線以上有利的微環(huán)境中生存，世界上海拔最高的植物是出現(xiàn)在喜馬拉雅山上6 100百米的馬卡魯峰。在這個高度上，被陽光溫暖過的巖石可以將 小雪 堆融化。
高山植物最突出的特點是其低矮的生長形態(tài)。這種特點使他們能夠避開大風最強勢的勢頭，并且有助于他們利用緊鄰地 面相 對較高的溫度。在這樣一個低溫限制生命的地區(qū)，地表提供的額外溫度是至關重要的。低矮的生長形態(tài)也可以幫助植物充分利用冬季積雪所提供的保溫環(huán)境。在赤道區(qū)的山脈上低矮的生長形態(tài)并不常見。

The Long-Term Stability of Ecosystems
Plant communities assemble themselves flexibly, and their particular structure depends on the specific history of the area. Ecologists use the term "succession" to refer to the changes that happen in plant communities and ecosystems over time. The first community in a succession is called a pioneer community, while the long-lived community at the end of succession is called a climax community. Pioneer and successional plant communities are said to change over periods from 1 to 500 years. These changes-in plant numbers and the mix of species-are cumulative. Climax communities themselves change but over periods of time greater than about 500 years.
An ecologist who studies a pond today may well find it relatively unchanged in a year's time. Individual fish may be replaced, but the number of fish will tend to be the same from one year to the next. We can say that the properties of an ecosystem are more stable than the individual organisms that compose the ecosystem.
At one time, ecologists believed that species diversity made ecosystems stable. They believed that the greater the diversity the more stable the ecosystem. Support for this idea came from the observation that long-lasting climax communities usually have more complex food webs and more species diversity than pioneer communities. Ecologists concluded that the apparent stability of climax ecosystems depended on their complexity. To take an extreme example, farmlands dominated by a single crop are so unstable that one year of bad weather or the invasion of a single pest can destroy the entire crop. In contrast, a complex climax community, such as a temperate forest, will tolerate considerable damage from weather to pests.
The question of ecosystem stability is complicated, however. The first problem is that ecologists do not all agree what "stability" means. Stability can be defined as simply lack of change. In that case, the climax community would be considered the most stable, since, by definition, it changes the least over time. Alternatively, stability can be defined as the speed with which an ecosystem returns to a particular form following a major disturbance, such as a fire. This kind of stability is also called resilience. In that case, climax communities would be the most fragile and the least stable, since they can require hundreds of years to return to the climax state.
Even the kind of stability defined as simple lack of change is not always associated with maximum diversity. At least in temperate zones, maximum diversity is often found in mid-successional stages, not in the climax community. once a redwood forest matures, for example, the kinds of species and the number of individuals growing on the forest floor are reduced. In general, diversity, by itself, does not ensure stability. Mathematical models of ecosystems likewise suggest that diversity does not guarantee ecosystem stability-just the opposite, in fact. A more complicated system is, in general, more likely than a simple system to break down. A fifteen-speed racing bicycle is more likely to break down than a child's tricycle.
Ecologists are especially interested to know what factors contribute to the resilience of communities because climax communities all over the world are being severely damaged or destroyed by human activities. The destruction caused by the volcanic explosion of Mount St. Helens, in the northwestern United States, for example, pales in comparison to the destruction caused by humans. We need to know what aspects of a community are most important to the community's resistance to destruction, as well as its recovery.
Many ecologists now think that the relative long-term stability of climax communities comes not from diversity but from the "patchiness" of the environment, an environment that varies from place to place supports more kinds of organisms than an environment that is uniform. A local population that goes extinct is quickly replaced by immigrants from an adjacent community. Even if the new population is of a different species, it can approximately fill the niche vacated by the extinct population and keep the food web intact.
Paragraph 1: Plant communities assemble themselves flexibly, and their particular structure depends on the specific history of the area. Ecologists use the term "succession" to refer to the changes that happen in plant communities and ecosystems over time. The first community in a succession is called a pioneer community, while the long-lived community at the end of succession is called a climax community. Pioneer and successional plant communities are said to change over periods from 1 to 500 years. These changes-in plant numbers and the mix of species-are cumulative. Climax communities themselves change but over periods of time greater than about 500 years.

1. The word "particular" in the passage is closest in meaning to
○natural
○final
○specific
○complex
2. According to paragraph 1, which of the following is NOT true of climax communities?
○They occur at the end of a succession.
○They last longer than any other type of community.
○The numbers of plants in them and the mix of species do not change.
○They remain stable for at least 500 years at a time.
Paragraph 2: An ecologist who studies a pond today may well find it relatively unchanged in a year's time. Individual fish may be replaced, but the number of fish will tend to be the same from one year to the next. We can say that the properties of an ecosystem are more stable than the individual organisms that compose the ecosystem.
3. According to paragraph 2, which of the following principles of ecosystems can be learned by studying a pond?
○Ecosystem properties change more slowly than individuals in the system.
○The stability of an ecosystem tends to change as individuals are replaced.
○Individual organisms are stable from one year to the next.
○A change in the members of an organism does not affect an ecosystem's properties.
Paragraph 3: At one time, ecologists believed that species diversity made ecosystems stable. They believed that the greater the diversity the more stable the ecosystem. Support for this idea came from the observation that long-lasting climax communities usually have more complex food webs and more species diversity than pioneer communities. Ecologists concluded that the apparent stability of climax ecosystems depended on their complexity. To take an extreme example, farmlands dominated by a single crop are so unstable that one year of bad weather or the invasion of a single pest can destroy the entire crop. In contrast, a complex climax community, such as a temperate forest, will tolerate considerable damage from weather to pests.
4. According to paragraph 3, ecologists once believed that which of the following illustrated the most stable ecosystems?
○Pioneer communities
○Climax communities
○Single-crop farmlands
○Successional plant communities
Paragraph 4: The question of ecosystem stability is complicated, however. The first problem is that ecologists do not all agree what "stability" means. Stability can be defined as simply lack of change. In that case, the climax community would be considered the most stable, since, by definition, it changes the least over time. Alternatively, stability can be defined as the speed with which an ecosystem returns to a particular form following a major disturbance, such as a fire. This kind of stability is also called resilience. In that case, climax communities would be the most fragile and the least stable, since they can require hundreds of years to return to the climax state.
5. According to paragraph 4, why is the question of ecosystem stability complicated?
○The reasons for ecosystem change are not always clear.
○Ecologists often confuse the word "stability" with the word "resilience."
○The exact meaning of the word "stability" is debated by ecologists.
○There are many different answers to ecological questions.
6. According to paragraph 4, which of the following is true of climax communities?○They are more resilient than pioneer communities.
○They can be considered both the most and the least stable communities.
○They are stable because they recover quickly after major disturbances.
○They are the most resilient communities because they change the least over time.
Paragraph 5: Even the kind of stability defined as simple lack of change is not always associated with maximum diversity. At least in temperate zones, maximum diversity is often found in mid-successional stages, not in the climax community. once a redwood forest matures, for example, the kinds of species and the number of individuals growing on the forest floor are reduced. In general, diversity, by itself, does not ensure stability. Mathematical models of ecosystems likewise suggest that diversity does not guarantee ecosystem stability-just the opposite, in fact. A more complicated system is, in general, more likely than a simple system to break down. A fifteen-speed racing bicycle is more likely to break down than a child's tricycle.
7. Which of the following can be inferred from paragraph 5 about redwood forests?
○They become less stable as they mature.
○They support many species when they reach climax.
○They are found in temperate zones.
○They have reduced diversity during mid-successional stages.
8. The word "guarantee" in the passage is closest in meaning to
○increase
○ensure
○favor
○complicate
9. In paragraph 5, why does the author provide the information that "A fifteen-speed racing bicycle is more likely to break down than a child's tricycle"?
○To illustrate a general principle about the stability of systems by using an everyday example
○To demonstrate that an understanding of stability in ecosystems can be applied to help understand stability in other situations
○To make a comparison that supports the claim that, in general, stability increases with diversity
○To provide an example that contradicts mathematical models of ecosystems
Paragraph 6: Ecologists are especially interested to know what factors contribute to the resilience of communities because climax communities all over the world are being severely damaged or destroyed by human activities. The destruction caused by the volcanic explosion of Mount St. Helens, in the northwestern United States, for example, pales in comparison to the destruction caused by humans. We need to know what aspects of a community are most important to the community's resistance to destruction, as well as its recovery.
10. The word "pales" in the passage is closest in meaning to
○increases proportionally
○differs
○loses significance
○is common
Paragraph 7: Many ecologists now think that the relative long-term stability of climax communities comes not from diversity but from the "patchiness" of the environment, an environment that varies from place to place supports more kinds of organisms than an environment that is uniform. A local population that goes extinct is quickly replaced by immigrants from an adjacentcommunity. Even if the new population is of a different species, it can approximately fill the niche vacated by the extinct population and keep the food web intact.

○Ecologists now think that the stability of an environment is a result of diversity rather than patchiness.
○Patchy environments that vary from place to place do not often have high species diversity.
○Uniform environments cannot be climax communities because they do not support as many types of organisms as patchy environments.
○A patchy environment is thought to increase stability because it is able to support a wide variety of organisms.

○foreign
○stable
○fluid
○neighboring

參考翻譯：生態(tài)系統(tǒng)的長期穩(wěn)定
植物群體可以自由地聚集，它們特殊的結構取決于聚集區(qū)域的具體歷史。生態(tài)學家使用"演替"來詮釋植物群落和生態(tài)系統(tǒng)隨著時間推移所發(fā)生的變化。演替中的第一個群落被稱作先鋒群落，而處于演替最后那個長期生存的群落被稱為頂極群落。先鋒群落和緊接著的植物群落的變化周期是從1到500年不等，植物數(shù)量和混合種類數(shù)量的變化是慢慢積累的。頂極群落本身也改變，但其變化周期超過500年。
現(xiàn)代一個研究池塘的生態(tài)學會發(fā)現(xiàn)池塘在一年當中相對而言是不變的。個別魚類可能被替換，但年復一年魚的總數(shù)都趨于一致。也就是說，一個生態(tài)系統(tǒng)自身的屬性要比由單一生物體組成的生態(tài)系統(tǒng)更穩(wěn)定。
生態(tài)學家們一度認為物種的多樣性使生態(tài)系統(tǒng)穩(wěn)定，生態(tài)系統(tǒng)物種越多樣則生態(tài)系統(tǒng)越穩(wěn)定。通過觀察得出的結論支持了這個觀點，長期持久的頂極群落通常要比先鋒群落具備更為復雜的食物網(wǎng)和更多的物種。生態(tài)學家家們得出的結論是：頂點生態(tài)系統(tǒng)的穩(wěn)定性明顯取決于他們的復雜化程度。舉個極端的例子，在單一作物的農田中，一年的惡劣天氣或單一害蟲的入侵就可以摧毀所有作物。與此相反，在一個復雜的頂極群落里，如溫帶森林，他們便可以抵御來自氣候和害蟲的干擾和入侵。
不管怎樣，生態(tài)系統(tǒng)穩(wěn)定性的問題非常復雜。首先，不是所有的生態(tài)學家都贊同"穩(wěn)定"的含義。穩(wěn)定性可以簡單地定義為缺乏變化。如果是這樣的話，頂極群落將被視為最穩(wěn)定的，因為根據(jù)定義，他們隨著時間推移而變化得最少。另外，穩(wěn)定性也可以界定為生態(tài)系統(tǒng)在經(jīng)歷了嚴重破壞之后回復原貌的速度，比如火災。這種穩(wěn)定性也被稱作彈性。在這種情況下，頂極群落將是最脆弱和最不穩(wěn)定的，因為他們可能需要數(shù)百年時間才能恢復到頂點狀態(tài)。
即使是這種被定義為簡單地缺乏變化的穩(wěn)定性并非總是與最多樣的物種聯(lián)系起來。至少在溫帶地區(qū)，會經(jīng)常在演替過程中發(fā)現(xiàn)最多物種，而不是在頂極群落中。例如，紅杉樹林一旦成熟，其中的物種數(shù)量以及單個物種的數(shù)量都會減少。一般來說，多樣性本身并不能保證穩(wěn)定性(事實上正相反)，生態(tài)系統(tǒng)的數(shù)學模型也可以得出同樣的結論。一個更復雜的系統(tǒng)可能比一個簡單的系統(tǒng)更容易被破壞(一個十五速的 賽車 比一個孩子的三輪車更容易損壞)。
生態(tài)學家們更想弄清楚到底哪些因素有助于促成群落的恢復，因為世界各地的頂極群落都因為人類活動而遭受到嚴重的損壞或毀壞。就像美國西北部圣海倫火山的猛烈噴發(fā)所造成的破壞，在人類活動對環(huán)境造成的破壞面前也相形見絀。我們必須了解對群落抵抗、破壞和恢復來說哪些是最重要的。
現(xiàn)在的很多生態(tài)學家們認為，頂極群落相對長期的穩(wěn)定性并非來自于多樣性，而是來自環(huán)境的"補綴"，隨處變化的環(huán)境比始終如一的環(huán)境更有利于多種有機體的生存。當?shù)匚锓N滅亡后，馬上就會被相鄰群落的移民取代。即便是另一種不同的物種，他們也可以填補那些已滅絕生物的空缺，并保持食物網(wǎng)的完整。
