The Vampire Diaries: The Fury Chapter Two

Stefan's voice was quietly savage. â€Å"That's what you wanted, wasn't it, Damon? And now you've got it. You had to make her like us, like you. It wasn't enough just to kill her.† Damon didn't glance back at him. He was looking at Elena intently through those hooded eyes, still kneeling there holding her chin. â€Å"That's the third time you've said that, and I'm getting a little tired of it,† he commented softly. Disheveled, still slightly out of breath, he was yet self-composed, in control. â€Å"Elena, did I kill you?† â€Å"Of course not,† Elena said, winding her fingers in those of his free hand. She was getting impatient. What were they talking about anyway? Nobody had been killed. â€Å"I never thought you were a liar,† Stefan said to Damon, the bitterness in his voice unchanged. â€Å"Just about everything else, but not that. I've never heard you try to cover up for yourself before.† â€Å"In another minute,† said Damon, â€Å"I'm going to lose my temper.† What more can you possibly do to me? Stefan returned. Killing me would be a mercy. â€Å"I ran out of mercy for you a century ago,† Damon said aloud. He let go, finally, of Elena's chin. â€Å"What do you remember about today?† he asked her. Elena spoke tiredly, like a child reciting a hated lesson. â€Å"Today was the Founders' Day celebration.† Flexing her fingers in his, she looked up at Damon. That was as far as she could get on her own, but it wasn't enough. Nettled, she tried to remember something else. â€Å"There was someone in the cafeteria†¦ Caroline.† She offered the name to him, pleased. â€Å"She was going to read my diary in front of everyone, and that was bad because†¦Ã¢â‚¬  Elena fumbled with the memory and lost it. â€Å"I don't remember why. But we tricked her.† She smiled at him warmly, conspiratorially. â€Å"Oh, ‘we' did, did we?† â€Å"Yes. You got it away from her. You did it for me.† The fingers of her free hand crept under his jacket, searching for the square-cornered hardness of the little book. â€Å"Because you love me,† she said, finding it and scratching at it lightly. â€Å"You do love me, don't you?† There was a faint sound from the center of the clearing. Elena looked and saw that Stefan had turned his face away. â€Å"Elena. What happened next?† Damon's voice called her back. â€Å"Next? Next Aunt Judith started arguing with me.† Elena pondered this a moment and at last shrugged. â€Å"Over†¦ something. I got angry. She's not my mother. She can't tell me what to do.† Damon's voice was dry. â€Å"I don't think that's going to be a problem anymore. What next?† Damon's voice was dry. â€Å"I don't think that's going to be a problem anymore. What next?† â€Å"And where did you go in Matt's car?† â€Å"To Wickery Bridge,† Stefan said, turning back toward them. His eyes were desolate. â€Å"No, to the boardinghouse,† Elena corrected, irritated. â€Å"To wait for†¦ mm†¦ I forget. Anyway, I waited there. Then†¦ then the storm started. Wind, rain, all that. I didn't like it. I got in the car. But something came after me.† â€Å"Someone came after you,† said Stefan, looking at Damon. â€Å"Some thing,† Elena insisted. She had had enough of his interruptions. â€Å"Let's go away somewhere, just us,† she said to Damon, kneeling up so that her face was close to his. â€Å"In a minute,† he said. â€Å"What kind of thing came after you?† She settled back, exasperated. â€Å"I don't know what kind of thing! It was like nothing I've ever seen. Not like you and Stefan. It was†¦Ã¢â‚¬  Images rippled through her mind. Mist flowing along the ground. The wind shrieking. A shape, white, enormous, looking as if it were made out of mist itself. Gaining on her like a wind-driven cloud. â€Å"Maybe it was just part of the storm,† she said. â€Å"But I thought it wanted to hurt me. I got away though.† Fiddling with the zipper to Damon's leather jacket, she smiled secretly and looked up at him through her lashes. For the first time, Damon's face showed emotion. His lips twisted in a grimace. â€Å"You got away.† â€Å"Yes. I remembered what†¦ someone†¦ told me about running water. Evil things can't cross it. So I drove toward Drowning Creek, toward the bridge. And then†¦Ã¢â‚¬  She hesitated, frowning, trying to find a solid memory in the new confusion. Water. She remembered water. And someone screaming. But nothing else. â€Å"And then I crossed it,† she concluded finally, brightly. â€Å"I must have, because here I am. And that's all. Can we go now?† Damon didn't answer her. â€Å"The car's still in the river,† said Stefan. He and Damon were looking at each other like two adults having a discussion over the head of an uncomprehending child, their hostilities suspended for the moment. Elena felt a surge of annoyance. She opened her mouth, but Stefan was continuing. â€Å"Bonnie and Meredith and I found it. I went underwater and got her, but by then†¦Ã¢â‚¬  By then, what? Elena frowned. Damon's lips were curved mockingly. â€Å"And you gave up on her? You, of all people, should have suspected what might happen. Or was the idea so repugnant to you that you couldn't even consider it? Would you rather she were really dead?† people, should have suspected what might happen. Or was the idea so repugnant to you that you couldn't even consider it? Would you rather she were really dead?† Elena opened her mouth again, but Damon laid two fingers on it to keep her quiet. He said smoothly, â€Å"And that's the problem now-or are you too blind to see that, too? You told me to look at her; look at her yourself. She's in shock, irrational. Oh, yes, even I admit that.† He paused for a blinding smile before going on. â€Å"It's more than just the normal confusion after changing. She'll need blood, human blood, or her body won't have the strength to finish the change. She'll die.† What do you mean irrational? Elena thought indignantly. â€Å"I'm fine,† she said around Damon's fingers. â€Å"I'm tired, that's all. I was going to sleep when I heard you two fighting, and I came to help you. And then you wouldn't even let me kill him,† she finished, disgusted. â€Å"Yes, why didn't you?† said Stefan. He was staring at Damon as if he could bore holes through him with his eyes. Any trace of cooperation on his part was gone. â€Å"It would have been the easiest thing to do.† Damon stared back at him, suddenly furious, his own animosity flooding up to meet Stefan's. He was breathing quickly and lightly. â€Å"Maybe I don't like things easy,† he hissed. Then he seemed to regain control of himself once more. His lips curled in mockery, and he added, â€Å"Put it this way, dear brother: if anyone's going to have the satisfaction of killing you, it will be me. No one else. I plan to take care of the job personally. And it's something I'm very good at; I promise you.† â€Å"You've shown us that,† Stefan said quietly, as if each word sickened him. â€Å"But this one,† Damon said, turning to Elena with glittering eyes, â€Å"I didn't kill. Why should I? I could have changed her any time I liked.† â€Å"Maybe because she had just gotten engaged to marry someone else.† Damon lifted Elena's hand, still twined with his. On the third finger a gold ring glittered, set with one deep blue stone. Elena frowned at it, vaguely remembering having seen it before. Then she shrugged and leaned against Damon wearily. â€Å"Well, now,† Damon said, looking down at her, â€Å"that doesn't seem to be much of a problem, does it? I think she may have been glad to forget you.† He looked up at Stefan with an unpleasant smile. â€Å"But we'll find out once she's herself again. We can ask her then which of us she chooses. Agreed?† Stefan shook his head. â€Å"How can you even suggest that? After what happened†¦Ã¢â‚¬  His voice trailed off. â€Å"With Katherine? I can say it, if you can't. Katherine made a foolish choice, and she paid the price for it. Elena is different; she knows her own mind. But it doesn't matter if you agree,† he added, overriding Stefan's new protests. â€Å"The fact is that she's weak now, and she needs blood. I'm going to see that she gets it, and then I'm going to find who did this to her. You can come or not. Suit yourself.† He stood, drawing Elena up with him. Let's go. She recognized the place where they left the wood. She had been there earlier today. Now, however, there was some sort of frenzied activity going on: red and blue lights flashing on cars, spotlights framing the dark huddled shapes of people. Elena looked at them curiously. Several were familiar. That woman, for instance, with the thin harrowed face and the anxious eyes-Aunt Judith? And the tall man beside her-Aunt Judith's fianc.., Robert? There should be someone else with them, Elena thought. A child with hair as pale as Elena's own. But try as she might, she could not conjure up a name. The two girls with their arms around each other, standing in a circle of officials, those two she remembered though. The little red-haired one who was crying was Bonnie. The taller one with the sweep of dark hair, Meredith. â€Å"But she's not in the water,† Bonnie was saying to a man in a uniform. Her voice trembled on the edge of hysteria. â€Å"We saw Stefan get her out. I've told you and told you.† â€Å"And you left him here with her?† â€Å"We had to. The storm was getting worse, and there was something coming-† â€Å"Never mind that,† Meredith broke in. She sounded only slightly calmer than Bonnie. â€Å"Stefan said that if he-had to leave her, he'd leave her lying under the willow trees.† â€Å"And just where is Stefan now?† another uniformed man asked. â€Å"We don't know. We went back to get help. He probably followed us. But as for what happened to-to Elena†¦Ã¢â‚¬  Bonnie turned back and buried her face in Meredith's shoulder. They're upset about me, Elena realized. How silly of them. I can clear that up, anyway. She started forward into the light, but Damon pulled her back. She looked at him, wounded. â€Å"Not like that. Pick the ones you want, and we'll draw them out,† he said. â€Å"Want for what?† â€Å"For feeding, Elena. You're a hunter now. Those are your prey.† Elena pushed her tongue against a canine tooth doubtfully. Nothing out there looked like food to her. Still, because Damon said so, she was inclined to give him the benefit of the doubt. â€Å"Whichever you think,† she said obligingly. Damon tilted his head back, eyes narrowed, scanning the scene like an expert evaluating a famous painting. â€Å"Well, how about a couple of nice paramedics?† Damon tilted his head back, eyes narrowed, scanning the scene like an expert evaluating a famous painting. â€Å"Well, how about a couple of nice paramedics?† Damon barely glanced over his shoulder at Stefan. â€Å"Why not?† â€Å"Because there've been enough attacks. She may need human blood, but she doesn't have to hunt for it.† Stefan's face was shut and hostile, but there was an air of grim determination about him. â€Å"There's another way?† Damon asked ironically. â€Å"You know there is. Find someone who's willing-or who can be influenced to be willing. Someone who would do it for Elena and who is strong enough to deal with this, mentally.† â€Å"And I suppose you know where we can find such a paragon of virtue?† â€Å"Bring her to the school. I'll meet you there,† Stefan said, and disappeared. They left the activity still bustling, lights flashing, people milling. As they went, Elena noticed a strange thing. In the middle of the river, illuminated by the spotlights, was an automobile. It was completely submerged except for the front fender, which stuck out of the water. What a stupid place to park a car, she thought, and followed Damon back into the woods. Stefan was beginning to feel again. It hurt. He'd thought he was through with hurting, through with feeling anything. When he'd pulled Elena's lifeless body out of the dark water, he'd thought that nothing could ever hurt again because nothing could match that moment. He'd been wrong. He stopped and stood with his good hand braced against a tree, head down, breathing deeply. When the red mists cleared and he could see again, he went on, but the burning ache in his chest continued undiminished. Stop thinking about her, he told himself, knowing that it was useless. But she wasn't truly dead. Didn't that count for something? He'd thought he would never hear her voice again, never feel her touch†¦ And now, when she touched him, she wanted to kill him. He stopped again, doubling over, afraid he was going to be sick. Seeing her like this was worse torture than seeing her lying cold and dead. Maybe that was why Damon had let him live. Maybe this was Damon's revenge. And maybe Stefan should just do what he'd planned to do after killing Damon. Wait until dawn and take off the silver ring that protected him from sunlight. Stand bathing in the fiery embrace of those rays until they burned the flesh from his bones and stopped the pain once and for all. Stefan detoured toward the boardinghouse. He needed to clean up before he could let humans see him. In his room, he washed the blood from his face and neck and examined his arm. The healing process had already begun, and with concentration he could accelerate it still further. He was burning up his Powers fast; the fight with his brother had already weakened him. But this was important. Not because of the pain-he scarcely noticed that-but because he needed to be fit. Damon and Elena were waiting outside the school. He could feel his brother's impatience and Elena's wild new presence there in the dark. â€Å"This had better work,† Damon said. Stefan said nothing. The school auditorium was another center of commotion. People ought to have been enjoying the Founders' Day dance; in fact, those who had remained through the storm were pacing around or gathered in small groups talking. Stefan looked in the open door, searching with his mind for one particular presence. He found it. A blond head was bent over a table in the corner. Matt. Matt straightened and looked around, puzzled. Stefan willed him to come outside. You need some fresh air, he thought, insinuating the suggestion into Matt's subconscious. You feel like just stepping out for a moment. To Damon, standing invisible just beyond the light, he said, Take her into the school, to the photography room. She knows where it is. Don't show yourselves until I say. Then he backed away and waited for Matt to appear. Matt came out, his drawn face turned up to the moonless sky. He started violently when Stefan spoke to him. â€Å"Stefan! You're here!† Desperation, hope, and horror struggled for dominance on his face. He hurried over to Stefan. â€Å"Did they-bring her back yet? Is there any news?† â€Å"What have you heard?† Matt stared at him a moment before answering. â€Å"Bonnie and Meredith came in saying that Elena had gone off of Wickery Bridge in my car. They said that she†¦Ã¢â‚¬  He paused and swallowed. â€Å"Stefan, it's not true, is it?† His eyes were pleading. Stefan looked away. â€Å"Oh, God,† Matt said hoarsely. He turned his back on Stefan, pressing the heels of his hands into his eyes. â€Å"I don't believe it; I don't. It can't be true.† â€Å"Matt†¦Ã¢â‚¬  He touched the other boy's shoulder. â€Å"I'm sorry.† Matt's voice was rough and ragged. â€Å"You must be going through hell, and here I am making it worse.† His only other option was to tell Matt the truth. Let Matt make his own choice, knowing everything. â€Å"If there were something you could do for Elena right now,† he said, â€Å"would you do it?† Matt was too lost in emotion to ask what kind of idiotic question that was. â€Å"Anything,† he said almost angrily, rubbing a sleeve over his eyes. â€Å"I'd do anything for her.† He looked at Stefan with something like defiance, his breathing shaky. Congratulations', Stefan thought, feeling the sudden yawning pit in his stomach. You've just won yourself a trip to the Twilight Zone. â€Å"Come with me,† he said. â€Å"I've got something to show you.†

Rhetoric from Homer to Augustine Essay Example | Topics and Well Written Essays - 750 words

Rhetoric from Homer to Augustine - Essay Example Antique civilization contributed a lot to our modern science and laid foundation of modern scientific conceptions of the world inside and outside of us. Rhetoric is just one point of ancient heritage. Rhetoric from Homer to Augustine went through the phase of its origin and becoming when fundament of this art was laid. 2. Rhetoric in Greece was one of the three liberal arts. So it was a very important art. In Homer days rhetoric was not widely developed yet, but it is possible to say that Homer's contribution to rhetoric is obvious. His epic poems "Iliad" and "Odyssey" were full of poetic dialogues, argumentations and word exercises for achieving different goals. His poetry influenced further poetic and rhetoric development in Greece. But in 5th century B. C. rhetoric became known for wide people through sophists. They thought people skill of argumentation. Sophists' work was valued rather high as they helped people to defend their personal interests, not always fair. So this form of teaching soon declined. Plato's teaching was another significant step to rhetoric development. He was an opponent for the sophists. ... Aristotle developed Plato's ideas and went further. He introduced rhetoric as a system of particular skills necessary for an orator. It was the next step of rhetoric development. Aristotle identified three main elements of rhetorical art: character of an orator, his emotions and his language. It is very important to feel the character of the audience, its structure - it will help to choose correct ways of influence on it. Orator's character and emotions must be directed to the goals of the speech - his speech must be emotionally-colored, bright and address everybody's hearts and feelings. The choice of appropriate language is also important. It in turn depends on the audience structure and goals to be achieved. So Aristotle's system influenced rhetoric very much and prepared fertile ground for its further rise and development.3. Rhetoric in Ancient Rome took much from that of Greece, but there were its own features. The main figures of Roman rhetoric were Cicero and Quintilian. Cicer o was one of the most brilliant orators of the ancient world. His speeches were full of expression, his influence on the audience was great, his oratorical methods were much imitated in his days and by later orators. Cicero's works on rhetoric were influenced this art in Rome and for further rhetoric development in general. Quintilian's treatise "Institutes of Oratory" was the next step of rhetorical skills systematization. He wrote about five main rhetorical canons. These are: development of an argument; its arrangement and organization for achieving an appropriate effect; definition of the speech style for a determined audience; speech delivery methods; orator's memory needed to keep in mind all elements of the speech. Quintilian's

Democracy and Socialism Essay Example | Topics and Well Written Essays - 750 words

Democracy and Socialism - Essay Example Since then, there have been turbulent times in a quest to achieve democracy with dictators and military coup leaders claiming to support it. However, in Athens, it followed a set of rules on who was legible to participate in politics, vote and the size of the society where democracy could be practiced. With this, the Athenians agreed that the people required population to be small so as to allow citizens access to debate attendances and vote on issues affecting them (History World, n.d). Over time, democracy has evolved with various societies that have implemented it. For example, with the Romans, representation in a legislative assembly came up so that selected few leaders could represent an entire population and their interests (History World, n.d). In addition, the Romans came up with the oral system of voting where citizens gave their answer of a specified question to a clerk who then recorded it. Moreover, with all the changes it has had to it, democracy has its positive and neg ative aspects that affect any society that embraces it. For example, the use of majority rule forces the minority who lost to be dictated upon by those who won (Cincotta, n.d). Therefore, it leads to the oppression of minority populations in a bid to enact the will of a majority. In addition, democratic rule puts its basis on a knowledgeable and educated citizen who is literate. This, in itself, is discriminative to the illiterate as they lose independence due to reliance on the learned to make decisions and implement policies that may not be known to them (Cincotta, n.d). As a result, democracy can be used for selfish gain, especially in the use of representatives. However, it is not all gloom for democracy as it bears positive aspects to it, as well. Democracy in exercising majority rule guarantees the protection of minority rights against violation in all aspects (Cincotta, n.d). This is because the rights of dissenters are not dependent on the goodwill of the majority who accent . Moreover, in democracy, the government only plays a minor role in the social organization that leads to pluralism (Cincotta, n.d). As a result, most social and private organizations and institutions remain free from the interference of the government. Socialism Socialism refers to a social system that advocates for liberty, equality and fraternity in its implementation (Cockshott & Cottrell, 2012). It traces its origins to a wide variety of influences that include its manifestation as a philosophy and the ideas of various scholars. Therefore, with its already established goals, it applied a hybrid of Christian communalism, feudalism and liberal capitalism to daily living (Daum, n.d). This made it utopian socialism and could be easily related to in the everyday life Socialism has a number of merits to it. This is because; it grants people liberty in the form of freedom from oppression and slavery, freedom of speech and association (Cockshott & Cottrell, 2012). In addition to this s ocialism grants freedom of conscience and separates the church form the state, as in traditional socialist states. In addition, socialism brings about equality in the society due to its nature in enforcing social values upon a society. Therefore, it allows for freedom in most social aspects in that all members of a society that practices socialism has access to the same opportunities (Cockshott &

The Way of Telling Lies and the Consequences Research Paper

The Way of Telling Lies and the Consequences - Research Paper Example This is a case comparable to that of sentencing a serial killer to death, so as to avoid their committing more killings or murders. From this example, the sentencing to death is equally causing death, but with the intent of putting an end to the deaths that the serial killer has caused, and those that they may continue to cause. Therefore, in avoiding the further deaths, a single death is justified, showing that in such a case, it is not wrongful to send such a person to death. This paper will discuss the causes and the reasons behind the lies made by different individuals, with the intent of showing that lies are a core part of the daily life of each individual, and a part that cannot be avoided – literally speaking. This will help shed more light on the issues and the challenges or circumstances that force people into making lies, as opposed to following the rightful path of telling the truth. From an analysis of the lies made by individuals, it is clear that the factors and the issues – often leading to the making of lies include solving sticky issues, avoiding trouble, protecting others from the truth that may hurt them and as an effort to make certain cases look better than they are. Other reasons for lying include lying so as to identify with certain groups, so as to act as examples for others, for example the case of a parent who tells children lies – that they were brilliant in school, so that the children can work harder. From this discussion, the writer will clearly show that lying or cheating – as wrongful as it may be – is a principal part of everyday life, and a key into effective living (Bakan 124-127; Brown & Levinson 168-174). Literature Review According to the BBC ethics guide, a website feature, lying is most probably the most common wrongful acts that are committed by individuals on a daily basis. The account explains that some researchers are quoted, as saying that lying is a fully unavoidable part of human nature. According to the account, most people would consent that lying is wrong, except in the case where it is committed for a good reason. Also, among the people that hold that lying is wrong, there is the problem that they shut the possibility of saving a certain course or situation, which may have been saved by making one lie. According to Sisela Bok (78), lying is a type of deception, but not all models of deception can qualify to be referred as lies. The account goes further to account that a lie has three basic characteristics, these including that it is made to communicate some information, that the liar plans to mislead, and that the liar is convinced that the information they offer is not right or truthful. However, the author goes further to account that, opposite to the belief of many, a lie does not have to offer false information, or get presented in a malicious manner – or with a wrongful intent. An example offered, is that of white lies, which are offered for good intentions. The definition of a lie, also includes, the case where an individual presents truthful information taking it to be a lie and in the cases of a known liar, who is not able to lie to others, because they know that they always tell lies. Therefore, from the diversity of the lies told, the source shows that lies form a core aspect of everyday

History Essay Example | Topics and Well Written Essays - 250 words - 18

History - Essay Example The ideologies of the movement would not have gained impetus if the print media had not yet flourished, which promoted a renewed interest in the discovery of knowledge especially among the elites. One of the founding centers of the Enlightenment was France. Voltaire (1694–1778) was a French radical thinker who epitomized the Enlightenment ideals of freedom of speech and rational thought over blind faith in religion. Baron de Montesquieu (1689–1755) was another Enlightenment figure who revolutionized political discourse. He praised the republic as the best form of government and paved way for the division of the executive, the legislative, and the judiciary. Diderot was the architect of the Encyclopedia which was published over a period of twenty one years (1751–1772). Though the Enlightenment ideals originated in France it spread to different parts of Europe and the world. Each country saw the emergence of a bunch of radical thinkers in various fields. In England it was epitomized by Isaac Newton. John Locke, Adam Smith, David Hume were the other exponents of the Enlightenment in England. In America the writings of Thomas Jefferson and Benjamin Franklin created waves. It encouraged a widespread thirst for knowledge among the elites and the cultivation of scientific rationalism. Many of these philosophes set the mood for a tremendous intellectual and cultural revolution which left no stone in the society unturned. In the essay let us look at the political, economic, and scientific ripples created by the Enlightenment across the world. Many leaders of the American Revolution like Thomas Jefferson, Benjamin Franklin, and Thomas Paine were greatly influenced by the English and French Enlightenment thought, especially John Locke’s idea of liberalism. The Enlightenment clearly defied the absolutism of monarchy and upheld democracy. The common man was tired of being suppressed under the absolutist monarchs and they were influenced by the teachings

Keystone Species Essay Example | Topics and Well Written Essays - 1750 words

Keystone Species - Essay Example The populations of big-cat prey including the red coati (Nasua nasua), the agouti (Dasyprocta variegata), and the paca (Agouti paca) are about ten times higher than on Cocha Cashu, Peru, where big cats still live. However, this increase may result from natural population variability rather than the lack of jaguars and pumas. The extreme removal of herbivores and frugivorous mammals would drastically affect forest regeneration, altering tree species composition, but the effects of modest changes in densities are less clear. The sea otter (Enhydra lutris) is a keystone predator par excellence (Duggins 1980). A population of around 200,000 once thrived on the kelp beds lying close to shore from northern Japan, through Alaska, to southern California and Mexico. In 1741, Vitus Bering, the Danish explorer, reported seeing great numbers of sea otters on his voyage among the islands of the Bering Sea and the North Pacific Ocean. Some furs were taken back to Russia and soon this new commodity was highly prized for coats. Hunting began. In 1857, Russia sold Alaska to the United States for $7,200,000. This cost was recouped in forty years by selling sea otter pelts. In 1885 alone, 118,000 sea otter pelts were sold. By 1910, the sea otter was close to extinction, with a world-wide population of fewer than 2,000. It was hardly ever seen along the Californian coast from 1911 until 1938. The inshore marine ecosystem changed where the sea otter disappeared. Sea urchins, which were eaten by the otters, underwent a population explosion. They consumed large portions of the kelp and other seaweeds. While the otters were present, the kelp formed a luxuriant underwater forest, reaching from the sea bed, where it was anchored, to the sea surface. With no otters to keep sea-urchins in check, the kelp vanished. Stretches of the shallow ocean floor were turned into sea-urchin barrens, which were a sort of submarine desert. Happily, a few pairs of sea otters had managed to survive in the outer Aleutian Islands and at a few localities along the southern Californian coast. Some of these were taken to intermediate sites in the United States and Canada where they were protected by strict measures. With a little help, the sea otters staged a comeback and the sea urchins declined. The lush kelp forest grew back and many lesser algae moved in, along with crustaceans, squids, fishes, and other organisms. Grey whales migrated closer to shore to park their young in breaks along the kelp edge while feeding on the dense concentrations of animal plankton. Keystone predators sometimes are more effective within certain parts of their range. The sea star (Pisaster ochraceus) is a keystone predator of rocky intertidal communities in western North America (Paine 1995). This starfish preys primarily on two mussels Mytilus californianus and Mytilus trossulus. A study along the central Oregon coast showed that three distinct predation regimes exist (Menge, B. A., and T. L. Freidenburg. 2001). Strong keystone predation occurs along wave-exposed headlands. Less strong predation by sea stars, whelks, and possibly other predators occurs in a wave-protected cove. Weak predation occurs at a wave-protected site regularly buried by sand. If keystone species do exist, how do the links within a system dominated by such a
