Reproduction A Courting To Nature Essays (902 words) - Mating
Reproduction: A Courting To Nature ====================================================================== REPRODUCTION: A-Courting to Nature! LIFE SCIENCES SIG ---------------------------------------------------------------------- For some time she had watched his movements, appearing coyly in his haunts. And now, had it paid off? Doubtless, he was in love. His muscles were taut; he swooped through the air more like an eagle than a Greylag gander. The only problem was, it was not for her that he then landed in a flurry of quacks and wingbeats, or for her that he dashed off surprise attacks on his fellows. It was, rather, for another - for her preening rival across the Bavarian lake. Poor goose. Will she mate with the gander of her dreams? Or will she trail him for years, laying infertile egg clutches as proof of her faithfulness? Either outcome is possible in an animal world marked daily by scenes of courtship, spurning and love triumphant. And take note: these are not the imaginings of some Disney screen-16 writer. Decades ago Konrad Lorenz, a famed Austrian naturalist, made detailed studies of Greylags and afterwards showed no hesitation in using words like love, grief and even embarrassment to describe the behavior of these large, social birds. At the same time he did not forget that all romance - animal and human - is tied intimately to natural selection. Natural selection brought on the evolution of males and females during prehistoric epochs when environmental change was making life difficult for single-sex species such as bacteria and algae. Generally, these reproduced by splitting into identical copies of themselves. New generations were thus no better than old ones at surviving in an altered world. With the emergence of the sexes, however, youngsters acquired the qualities of two parents. This meant that they were different from both - different and perhaps better at coping with tough problems of survival. At the same time, nature had to furnish a new set of instincts which would make "parents" out of such unreflective entities as mollusks and jellyfish.. The peacock's splendid feathers, the firefly's flash, the humpback whale's resounding bellow - all are means these animals have evolved to obey nature's command: "Find a mate. Transmit your characteristics through time!" But while most males would accept indiscriminate mating, females generally have more on their minds. In most species, after all, they take on reproduction's hardest chores such as carrying young, incubating eggs and tending newborns. Often they can produce only a few young in a lifetime. (Given half a chance, most males would spawn thousands.) So it's no surprising that the ladies are choosy. They want to match their characteristics with those of a successful mate. He may flap his wings or join a hockey team, but somehow he must show that his offspring will not likely be last to eat or first in predatory jaws. Strolling through the Australian underbrush that morning, she had seen nothing that might catch a female bowerbird's eye. True, several males along the way had built avenue bowers - twin rows of twigs lined up north and south. True, they had decorated their constructions with plant juices and charcoal. Yet they displayed nothing out front! Not a beetle's wing. Not a piece of flower. Then she saw him. He stood before the largest bower and in his mouth held a most beautiful object. It was a powder blue cigarette package, and beneath it there glinted a pair of pilfered car keys. Without hesitation she hopped forward to watch his ritual dance. Males have found many ways to prove their worth. Some, like bowerbirds, flaunt possessions and territory, defending these aggressively against the intrusion of fellow males. Others, like many birds and meat-eating mammals, pantomime nest building or otherwise demonstrate their capacity as dads. Still others, however, do nothing. Gentlemen may bring flowers, but most male fish just fertilize an egg pile some unknown female has left in underwater sand. For a fish, survival itself is a romantic feat. For other species, though, love demands supreme sacrifices. Shortly after alighting on the back of his mate, the male praying mantis probably had no idea what was in store. This would have been a good thing too, because as he continued to fertilize his partner's eggs, she twisted slowly around and bit off his head. She continued to put away his body parts until well nourished and thus more able to sustain her developing young. Luckily for most species, the urge to mate come on only occasionally, usually in springtime. For love can hurt, particularly if you intended has difficulty telling a mate from a meal. Pity the poor male of the spider species, Xysticus Cristatus, for instance. His only

Syria and the Revolution
Syria and the Revolution Introduction The Arab wave of unrest began in Tunisia in December 2010, and led to the ousting of Zine el-Abidine Ben Ali, who had ruled the country for 23 years. The revolution in this small North African country was characterized by demonstrations and riots, which were quelled violently by the police and other state security agencies (Barnard and Cowell 2).Advertising We will write a custom essay sample on Syria and the Revolution specifically for you for only $16.05 $11/page Learn More However, the protestors relentlessly pursued their course and on 14th January 2011, 28 days after, the president resigned and fled to Saudi Arabia. This revolution was replicated in Egypt on 25th January 2011 and on February 11 2011; Hosni Mubarak resigned, ending his 30 years reign over the country. The wave of Arab revolution hit Syria on 15th march 2011 (Barnard and Cowell 2). It all started in a small southern city, whose residents held street protests after students wh o had displayed anti-government graffiti were tortured. The government used extreme force on the protestors and the demonstrations spread rapidly to various other parts of the country. The confrontations between protestors and government security agencies have left several people dead and injured and are threatening to escalate into a civil war. President Bashar al-Assad and members of his family continue holding onto power despite the international and internal pressure to end violence against civilians and allow political change (Barnard and Cowell 2) Background Information on Revolution Syria has a population of about 21 million people and is under the authoritarian rule headed by President Bashar al-Assad. The constitution authorizes supremacy of leaders from the Baath Party in the society and state institutions (Sharp 1). Party members and President Assadââ¬â¢s family dominate the three arms of the government. Syria has had a state of emergency since 1963, which grants secur ity agencies enormous power of suppressing any opposition (Sharp 1).Advertising Looking for essay on history?

Although protests started in a smaller marginalized town, their intensity has been more in larger cities of Aleppo and Damascus. This is a clear indication that people in larger towns are more opposed to Assadââ¬â¢s regime as they experience the problems mentioned above firsthand (Sharp 2). Key Players in the Revolution Opposition Groups and Demonstrators Most demonstrators are politically conversant and frustrated males between the ages of 20 to 40 years (Ecoi.Net par. 4). Although the Syrian opposition groups have become more orga nized during the revolution, they still remain largely divided over leadership, coordination, tactics and strategy. The Local Coordinating Councils present in many regions, played a vital role during the protest stage of the revolution as it linked activists from all over the country using informal networks (Sharp 3). Armed activists from Syria and other neighboring countries joined in the foray, as the unrest moved to greater heights of confrontations and violence. Some of the major opposition groups currently involved in the conflict are discussed below; The Free Syrian Army (FSA)-This group is made up of dissident military officers and personnel who defected from the government. They are armed and mainly attack government troops. The group is made up of individual security personnel, who defied orders to ruthlessly attack civilian protestors. Earlier this year, the FSA swore to put more effort in dealing with government troops that were using excessive force on civilians. FSA th reatened to attack more military security centers, because they were used by the government in attacking and suppressing the Syrian people (Sharp 3). The Syrian National Council (SNC) This group that was formed in October 2011 in Turkey is made up of external activists. The group wants the government to call off the crackdown on protestors and protect civilians (Sharp 3). The National Coordination Commission of the Forces of Democratic Change (NCC) This is an alliance of leftist groups based in Syria and Kurdish activists. The group is against any civilian protection that involves external militaries and is willing to dialogue with the government, as long ruthless attacks on protestors cease (Sharp 3). These oppositions groups justify that they have resulted into using force to repress the excessive violent tactics used by the government security agencies to quell the riots. Assadââ¬â¢s regime has condemned attacks on the police and military forces by these opposition groups t hat have been termed as terrorist groups. The ethnic divisions in Syria further complicate the conflict since the countyââ¬â¢s elite and Assadââ¬â¢s family belong to the minority Alawite faction, in this largely Sunni country (Sharp 4).Advertising We will write a custom essay sample on Syria and the Revolution specifically for you for only $16.05 $11/page Learn More Government Forces Assadââ¬â¢s regime has dealt ruthlessly with popular protests and opposition. Security forces and the military have been used in suppressing peaceful protests across the country. The Shabbiha or the Alawite civilian militia has been used by Assadââ¬â¢s regime to mete out violence on innocent civilians. One year since the revolution began; the government forces have continued to viciously crash any opposition (Sharp 5). In March 2012, the government unleashed bloody attacks on insurgentsââ¬â¢ strongholds of Idlib and Homs. According to United Nations, more than 9, 000 Syrians have lost their lives and thousands have been displaced since March 2011, when the unrest began (Sharp 5). Assadââ¬â¢s Reaction to the Revolution President al-Assad announced some reforms as a result of criticism from international communities and growing protests. He also gave amnesty to various groups of prisoners and some were freed. Assad also passed orders permitting peaceful demonstrations under certain situations and allowed the legal registration of other political parties apart from Baââ¬â¢ath. He also lifted the state of emergency that had been in place for 48 years. On December 19th 2011, Assadââ¬â¢s government opened a national dialogue aimed at creating a multiparty democracy. However, opposition leaders in the country boycotted this event. Recently, Assadââ¬â¢s government called for a referendum on the new constitution on 26 February 2012 (Ecoi.Net par. 9). This new constitution stipulates that it will end Baââ¬â¢ath party supremacy, but best ows most of the powers on Bashar al-Assad. According to Syrian state television, 89 percent of Syrians supported the new constitution in the referendum. The West and opposition activists shunned these results, as they saw this as a new strategy by Asad to hold unto power.Advertising Looking for essay on history? Let's see if we can help you! Get your first paper with 15% OFF Learn More Violation of Human Rights During the revolution, numerous abuses of human rights have been witnessed. Apart from the extensive systematic attacks on the civilian population organized and executed by state security forces, deaths in custody have also been reported. According to Amnesty International, 88 deaths have occurred in state custodies between April 1st and August 15th 2011. It is also estimated that not less than 190 people including children, have died while in custody (Ecoi.Net par. 10). Violation of human rights has also been witnessed in state hospitals where injured people are taken for treatment. People injured during demonstrations have reportedly been physically and verbally abused by the medical staff and sometimes deprived of medical care. People taken to hospitals have also been detained and arrested by security forces (Ecoi.Net par. 13) Vocal Syrian activists living abroad have not been spared either, as they are systematically harassed by embassy officials. Their families in Syria have been constantly harassed and intimidated by government authorities. The Syrian security has tortured and captured children during the one year of uprising. Some children have been shot in the streets or at home, while others have been captured and kept in inhumane environments. Schools have been used as military barracks, bases, sniper posts or detention centers. (Ecoi.Net par.143) International Response to Revolution Although condemnation for Assadââ¬â¢s regime has been wide from all corners of the world, most external players have failed in their efforts to stop the bloodshed. The Arab League expelled Syria from its council after it violated a peace plan that pledged to allow peaceful protests by pulling out the army from the streets. Assadââ¬â¢s government never honored the promise, but instead intensified the crack down on protesters. On 19th December 2011, the government agreed to fully cooperate with the Arab League by allowing an observer mission into the country (Ecoi.Net par. 15). The leagues presence did not improve the situation, as the government forces continued meting out violence on protesters (Ecoi.Net par. 25). The Arab league also formulated a transition plan that was presented to the United Nations Security Council. This plan was vetoed by China and Russia, who are permanent members of the Security Council. The international community opposing Assadââ¬â¢s regime can only undertake a collective action with the assistance of Syrian people, since the UN backed mandate failed. The EU and the US as well as the Arab league placed economic sanctions on Syria. It also put an embargo on exportation of weapons to the country and banned it member states from purchasing oil from Syria. The EU also banned the delivery of bank notes to the central bank of Syria and prohibited the trade of precious metals and gold with the state (Ecoi.Net par. 21). The EU also banned cargo flights from the country. The US has frozen all Syr ian government assets that are within its jurisdiction and banned US residents from performing any transactions with blacklisted individuals within the Syrian government. Turkey and Arab league have also followed suit and banned any transactions with Assadââ¬â¢s government. Assadââ¬â¢s government has found allies, with Russia sending a shipment of arms for the Syrian troops. Iran is another close ally that has sent cash, arms and advisors to Syria. It also assists Syria in exporting its oil abroad. Hezbollah from Lebanon has also declared its support for Assadââ¬â¢s regime. Conclusion President Assad is using the massive firepower to hold unto power and prevent the opposition from seizing power in any region. Assadââ¬â¢s strategy to hold on to power involves using ruthless crackdowns on opposition, thus preventing them from forming an effective, cohesive leadership. However, the protests threaten to escalate into a full civil war with tension already spilling over to oth er regions such as Jordan, turkey, Iraq and Lebanon (Barnard and Cowell 2). The latest efforts to end the one year bloody revolution are through a plan formulated by Kofi Annan, the former UN secretary. The plan proposes six points that will be used in ending the violence in Syria. These include; releasing prisoners, allowing journalistsââ¬â¢ access, permitting free movement, withdrawing heavy troops and weapons from civilian centers and allowing humanitarian assistance. Assad has warmed up to this plan as well as the Arab League, which has dropped its initial demands for the president to step down (Siddique and Whitaker 10).

World War I Essay Example | Topics and Well Written Essays - 2500 words
World War I - Essay Example The first allies included the United Kingdom, France and Russia; the central powers included Germany, Italy and Austria-Hungary. During World War I, more than 70 million military officers took part in the war with about 60 million being of European origin. By the end of the conflict, nearly 9 million military officers had been killed. There were various causes of the war, which included both short term and long term. The imperialistic polices imposed by great powers such as German, Russian empire, Austro-Hungarian and Ottoman empires caused conflicts between different powers plunging them into wars. The assassination of Franz Ferdinand in 1914 was also a possible cause of the World War I. After these triggers, different alliances that had been organized before were revived. Austro-Hungarian started the conflict by invading Serbia. This invasion triggered Germany into invading Belgium. Russia and France invaded Germany to counter its advancement into Belgium. The war spread across Eur ope and colonies of the different powers and the world war was on. Causes of World War I At the beginning of the nineteenth century, different powers across Europe started organizing themselves into alliances. These alliances resulted in the formation of complex military and political networks that included European powers. The Holly Alliance was the first alliance to be established and it included Persia, Russia, and Austria. In 1879, the Dual Alliance that included the German empire and Austria-hungry was established to suppress the earlier alliance between Russia and Persia. The formation of these alliances posed a major threat the Great Britain, which entered into an alliance with France and Russia. Although the formation of the dual alliance was intended to counter the Russian advancement into western territories s, the United Kingdom considered it as a major threat to its existence. The dual alliance was formed with the intention of countering Russian influence over the Ottoma n Empire and the Balkan. Each of these alliances was established under treaties that were meant protect the interests of countries in a particular league. The treaties were also aimed at preventing the entry of allied powers. The major treaties signed immediately before World War I included the Reinsurance treaty between the Germans and the Russians, the Franc-Russian alliance and Anglo-Russian alliance (Cross 121). Each of these treaties had the purpose of securing the interests of the concerned parties against the influence or invasion by allied powers. It is also evident that most of these treaties targeted Russia. Treaties were formed either to counter Russian advancement or to incorporate Russia in to a particular alliance. Russia was considered as a major power in Europe and, therefore most countries needed to protect their interest against Russia through formation of alliances. The World War I took place after European industrial and economic revolutions. These advancements m ay have triggered rivalry among different European powers. In the beginning of the nineteenth century, industrial advancement started to concentrate on the production of military equipment. Technology was applied to produce of warships and machine guns that have never been in any battlefield. Germany and Britain were the leading European countries in the production of military equipment. Industrial advancement in Germany and Britain made the two countries to enter into an arm race which later spread to the rest of Europe. By the end of 1910, most European countries had increased their military spending by over 50% of their GDP (Halpern 192). This allocation was used to produce military equipment, military training, and paying allowances to
