The year 1900 saw the now famous rediscovery of Mendel’s Laws by Carl Correns in Germany, Hugo de Vries in the Netherlands and Erich von Tschermak-Seysenegg in Austria. Their achievement was to realise that Mendel had not merely conducted experiments in successful hybridisation but had in fact studied the heredity of specific characteristics as they were passed on from parent plants to their offspring. Did Mendel work correctly ? I. Statistics of offspring data As Mendel’s fundamental insights into the principles of heredity in plants and animals came to be used on an ever wider basis, and with the advent of variation statistics, the numerical proportions which Mendel had deduced from his experiments came under fire. In 1936, for instance, the British mathematician R.A. Fisher prompted a discussion of the question whether Mendel had adjusted the observed segregation ratio to accommodate his predictions - in other words, whether he had falsified his results. Fisher based his argument on the supposition that Mendel’s segregation ratios were far higher than the principles of variation statistics would permit. Such segregation ratios, Fisher asserted, could occur only very seldom. In 1968 the AustrianSwedish genetic scientist H. Lamprecht disproved Fisher’s assertions. Lamprecht’s own experiments with the hybridisation of pea plants produced segregation ratios that in some cases even more closely matched the expected EAE I TEXTS, 2007-2008, p. 4 values. In 1983 the German doctor and botanist F. Weiling conducted biometric experiments which showed that Fisher’s studies had in several instances been based on erroneous or inapposite statistical assumptions. Only a few weeks ago J. Vollmann, working at the Institute of Plant Structure and Plant Breeding at Vienna’s University of Soil Cultivation, carried out computer simulations which showed that just thirty hybridisation simulations with a hypothetical number of 5,000 offspring produced an almost perfect match with Mendel’s 3:1 ratio. Analysing all of Mendel’s results (including those that were not published) produces a ratio of 6022:2000 with an error margin of under 1.5%. Did Mendel work correctly ? II. Independence of characteristics Mendel’s observation of the independent inheritance of characteristics also prompted critical comment. The probability of finding seven characteristics located one on each of the seven chromosomes of the garden pea is demonstrably 1:163. As we now know, two pairs of the characteristics studied by Mendel are located on chromosome 1 and chromosome 4. However, it is seldom that both characteristics are passed on together (coupling). The questions of whether Mendel was simply fortunate in his selection of characteristics, whether he had conducted preliminary experiments with certain genotypes before choosing his characteristics, and whether he came across divergent segregation ratios are currently still under discussion. Mendel’s scientific achievement Mendel’s outstanding intellectual achievement as a scientist was his ability to make deductions from the observed results of individual experiments — in other words, to perceive a distinct pattern despite the random inaccuracies of a few observations. This enabled him, for example, to ascertain the 3:1 segregation ratio in the heredity of red and white pea flowers in the face of a diversity of possible hereditary patterns. This insight long predated the advent of biometrics or even of probability calculus.

For many countries in the Organisation for Economic Cooperation and Development (OECD), the benefits to farmers are also perceived as a good way to reduce the costs and market distortions of their existing farm support policies, which now total about US$320 billion a year. Moreover, whereas oil and coal are unevenly distributed among countries, all countries could generate some bioenergy from domestically grown biomass of one type or another, thereby helping to reduce their dependence on imported fossil fuels...

EAE I TEXTS, 2007-2008, p. 6 ENGLISH I FOR AGRICULTURAL ENGINEERING (AND RELATED SCIENCES) E.T.S.I.A-UPV 2007-2008 The composition of soil; text #4 From http://www.publicbookshelf.com/public_html/The_Househ old_Cyclopedia_of_General_Information/compositio_g.ht ml Soils consist mostly of sand, lime, and clay, with certain saline and organic substances in smaller and varying proportions; but the examination of the ashes of plants shows that a fertile soil must of necessity contain an appreciable quantity of at least eleven different substances, which in most cases exist in greater or less relative abundance in the ash of cultivated plants; and of these the proportions are not by any means immaterial. In general, the soils which are made up of the most various materials are called alluvial; having been formed from the depositions of floods and rivers. Many of them are extremely fertile. Soils consist of two parts; of an organic part, which can readily be burned away when the surface-soil is heated to redness; and of an inorganic part, which remains fixed in the fire, consisting of earthy and saline substances from which, if carbonic acid or any elastic gas be present, it may, however, be driven by the heat. The organic part of soils is derived chiefly from the remains of vegetables and animals which have lived and died in and upon the soil, which have been spread over it by rivers and rains, or which have been added by the industry of man for the purposes of increased fertility. This organic part varies much in quantity, as well as quality, in different soils. In peaty soils it is very abundant, as well as in some rich, long cultivated lands. In general, it rarely amounts to one-fourth, or 25 per cent. even in our best arable lands. Good wheat soils contain often as little as eight parts in the hundred of organic animal or vegetable matter; oats and rye will grow in a soil containing only 1 1/2 per cent.; and barley when only two or three parts per cent. are present. EAE I TEXTS, 2007-2008, p. 7 The inorganic portion of any given soil, again, is divisible into two portions; that part which is soluble in water, and thus easily taken up by plants, and a much more bulky portion which is insoluble. Sir Humphrey Davy found the following to be the composition of a good productive soil. In every 9 parts, 8 consisted of siliceous sand; the remaining (one-ninth) part was composed, in 100 parts, as follows: Carbonate of lime (chalk) 63 grains. Pure silex 15 grains. Pure alumina, or the earth of clay 11 grains. Oxide (rust) of iron 3 grains. Vegetable and other saline matter 5 grains. Moisture and loss 3 grains. Thus the whole amount of organic matter in this instance is only 1 part in 200, or onehalf of one per cent.; a fact which, in itself, would demonstrate the fallacy of supposing that decomposed animal and vegetable matter in the soil form the exclusive supply to growing plants.

This could in turn affect how crop residues break down in the soil. Although the evidence to date does not support this claim, it is important that more studies are carried out to learn more. The interactions of soil micro-organisms can be complex – indeed most of them have yet to be fully identified. As scientists and farmers increase their knowledge, the effects of different crops and agricultural practices will become apparent for both the existing and new technologies.

The four main sources of water pollution are outlined in the table below: EAE I TEXTS, 2007-2008, p. 10 Water pollution can have a big impact on humans, animals and plants. The process of breaking down sewage can use up a lot of oxygen. This lack of oxygen in the water can kill plants and animals. River pollution can increase nitrate levels. Too many nitrates encourage the growth of algae. The algae use up oxygen supplies. Algae grows rapidly and blocks out valuable sunlight. Water pollution can also have an impact on human health. As well as affecting the quality of drinking water, pollution can also get into the human food chain for example, via fish.

Water management means controlling the supply and distribution of available water, and monitoring water quality. In England and Wales this is carried out by local authorities. Water supplies can be damaged by various kinds of pollution, and this can have a damaging impact on the environment and human health. EAE I TEXTS, 2007-2008, p. 13 Managing water supplies Water management involves: Providing people with a reliable source of water Maintaining the quality of water supplies In places where there are persistent water shortages, managing the supply may also mean rationing water so that it is available to those who need it most. In the UK there is enough water to meet demand, but water supplies are not evenly distributed around the country, and not necessarily located where demand is highest. For example some of the highest demand for water is in the highly-populated southeast of the country. However, the heaviest rainfall occurs in the relatively thinly-populated north and west. So in the UK water management means moving supplies around to meet demand. Water management: filterbeds in a UK water storage and treatment plant In England and Wales, local water authorities manage water supplies. Each water authority is based around a major river basin. Each authority has responsibility for: collecting water supplies distributing water supplies monitoring pollution levels reducing pollution levels monitoring and regulating the use of rivers, lakes and reservoirs There are several ways in which the water authorities can carry out their work: New reservoirs can be built to collect and store water Water can be transferred by pipe from a place of good supply to a place of high demand EAE I TEXTS, 2007-2008, p. 14 People can be educated to conserve water Maintaining pipe networks to prevent leakage Regulating and monitoring the amount of water people use through measures like hosepipe bans and water meters Post-Reading task: Discussion exercise.

Learn more about EFSA* work on GMOs Genetically modified (GM) foods can only be used in the European Union if they have passed a rigorous safety assessment. The procedures for evaluation and authorisation of GM foods are laid down in Regulation (EC) 1829/2003 on GM food and feed, which came into force in April 2004 and in Directive 2001/18/EC on the deliberate release into the environment of GMO’s, which came into force in March 2001. What is EFSA’s role? EFSA is Europe’s food safety ‘checkpoint’ and its role in the approval of GMOs is to provide scientific advice to European Union Institutions and Member States on the safety and risks for human and animal health and also for the environment. EFSA publishes its advice on its website and informs the requesting body of its conclusions. This information is taken into account by the requesting legislating body – European Commission and Member States – in line with the respective procedure when giving or refusing approval for use of GMO products. EFSA also carries out ‘self-tasking’ activities. ‘Self-tasking’ occurs when EFSA, during the course of its regular work, identifies a particular issue which it believes requires further analysis and research. In the context of GMOs, an example of this is the creation of a self-tasking working group to study requirements for Post Market Environmental Monitoring in order to provide guidance for applicants and regulatory authorities.

Your summary will be assessed by your teacher. Plantations for biofuels may threaten forests and wildlife A UN report warns that a hasty switch to biofuels could have major impacts on livelihoods and the environment. Produced by a cross-agency body, UN Energy, the report says that biofuels can bring real benefits. But there can be serious consequences if forests are razed for plantations, if EAE I TEXTS, 2007-2008, p. 21 food prices rise and if communities are excluded from ownership, it says. And it concludes that biofuels are more effective when used for heat and power rather than in transport. "Current research concludes that using biomass for combined heat and power (CHP), rather than for transport fuels or other uses, is the best option for reducing greenhouse gas emissions in the next decade - and also one of the cheapest," it says. The European Union and the US have recently set major targets for the expansion of biofuels in road vehicles, for which ethanol and biodiesel are seen as the only currently viable alternative to petroleum fuels. Forest clearance The UN report, Sustainable Bioenergy: A Framework for Decision Makers, suggests that biofuels can be a force for good if they are planned well, but can bring adverse consequences if not. "The development of new bioenergy industries could provide clean energy services to millions of people who currently lack them," it concludes, "while generating income and creating jobs in poorer areas of the world." But the prices of food, land and agricultural commodities could be driven up, it warns, with major impacts in poorer countries where people spend a much greater share of their incomes on food than in developed nations. On the environmental side, it notes that demand for biofuels has accelerated the clearing of primary forest for palm plantations, particularly in southeast Asia. Intensive farming of energy crops demands water and resources This destruction of ecosystems which remove carbon from the atmosphere can lead to a net increase in emissions. The report warns too of the impacts on nature: "Use of large-scale mono- EAE I TEXTS, 2007-2008, p. 22 cropping could lead to significant biodiversity loss, soil erosion and nutrient leaching." This has been avoided, the report says, in the Brazilian state of Sao Paulo where sugar cane farmers are obliged to leave a percentage of their land as natural reserves. Water is also a concern. The expanding world population and the on-going switch towards consumption of meat and dairy produce as incomes rise are already putting pressure on freshwater supplies, which increased growing of biofuel crops could exacerbate. In conclusion, UN Energy suggests policymakers should take a holistic look before embarking on drives to boost biofuel use. "Only through a convergence of biodiversity, greenhouse gas emissions and water-use policies can bioenergy find its proper environmental context and agricultural scale," the report concludes.

HTTP://WWW.FAO.ORG/DOCREP/T0690E/T0690E04.HTM The body is made up of many, many millions of cells which you can not see unless you use a microscope. Special cells come together to make an organ. An organ is a complex structure within the body. It has a special job or jobs to do. A body system consists of a number of organs which work together to carry out a special job. The animal body is made of 9 systems: Musculo-skeletal system Digestive system Circulatory system Respiratory system Urinary system Nervous system Sensory system Reproductive system Lympho-reticular system The organs of the animal body An organ is a complex structure with a special job or a number of jobs to do. For example: EAE I TEXTS, 2007-2008, p. 24 The eye is the organ of sight. The kidneys are organs which get rid of water and poisonous materials from the body as urine. The liver has many jobs and is involved in more than one system. Various organs are grouped together to form a body system which carries out a special job. System of the Organs in the Body Job or function Body Musculo-skeletal muscle (meat) bones Support and move the body Digestive Digest and absorb feed stomach, liver, intestine, pancreas Circulatory heart, blood vessels The brood carries substances around the body Respiratory muzzle, windpipe, lungs Breathing Urinary kidneys, bladder Get rid of poisons and waste (urine) Nervous brain, nerves spinal cord Pass messages around the body, control the body Sensory eyes, ears, nose skin Sense and detect things outside the body Reproductive testes, penis ovaries, uterus, To produce and feed young vagina, vulva, udder Lympho-reticular lymph nodes, spleen Protect against infectious diseases, produce blood The musculo-skeletal system This system consists of the bones and the muscles (meat).The bones form the skeleton which is the framework within the body. It carries weight and supports the body. Bones are connected together so they can move. The places where this happens are called joints. The bones are held together at the joints by elastic strands called ligaments. Between the bones is a softer material called cartilage (gristle) which EAE I TEXTS, 2007-2008, p. 25 cushions the bones at the joints when the body moves. Bones are very hard and contain minerals. Each bone has a name such as the scapula (shoulder blade) and skull (head). There are about 200 bones in the body. Muscles are joined at both ends to the bones. The muscles are the meat of the body and when they contract (shorten) or relax (lengthen) they make the bones move. If you bend your arm you can see and feel the muscles in your arm working. The digestive system The digestive system consists of the teeth, mouth, gullet (oesophagus), stomach, liver, intestine, pancreas, and rectum. Digestion begins in the mouth where feed is broken down into small pieces by the teeth and mixed with saliva before being swallowed. In the stomach feed is mixed with the juices to form a soft paste. This then passes into the intestine where bile from the liver and juices from the pancreas are added. The action of these juices is to break down the feed and allow the nourishment it contains to be absorbed by the blood in the walls of the intestine. Waste matter collects in the rectum and passes out of the body through the anus (or cloaca in birds). The digestive system The circulatory system and blood The organs of the circulatory system are the heart and the blood vessels (tubes). The heart is found in the chest cavity. It is a muscular pump which sends blood around the body. The blood vessels which carry blood away from the heart are called arteries. Blood returns to the heart in veins. Joining the arteries and veins is a fine network of small tubes called capillaries. The capillaries pass through every part of the body. When the heart beats its muscles contract and sends blood out through the arteries. When the heart relaxes blood flows into it from the veins. EAE I TEXTS, 2007-2008, p. 26 Every time the heart beats it sends a pulse along the arteries. You can feel it at certain points on the body. By feeling the pulse we can count the rate at which the heart beats (see Unit 5). You can feel your pulse on your wrist. The respiratory system Respiration (breathing) consists of inspiration (breathing in) and expiration (breathing out). There are two lungs which are found in the chest protected by the bony cage of the ribs. The windpipe carries air from the nostrils to the lungs which are spongy because of air spaces in them. As the animal breathes, air moves in and out of the lungs. Inside the lungs oxygen needed by the body passes into the blood in the walls of the lungs and water and carbon dioxide pass out of the blood into the air which is then breathed out. The respiratory system The urinary system The main organs are the two kidneys, which lie against the backbone, and the bladder. Waste materials and water are taken out of the blood in the kidneys. This forms urine. Urine collects in the bladder then passes out of the body. Nervous system and sensory system The bones of the skull and backbone protect the soft brain and spinal cord. Fibres called nerves pass from the brain and spinal cord to all parts of the Messages pass from the various parts of the body along the nerves to the brain. The brain sends a message back telling the different parts of the body what to do. EAE I TEXTS, 2007-2008, p. 27 The brain controls the body. Nervous system The brain also controls the senses, the sense organs are: the eyes for sight the ears for hearing the nose for smell the tongue for taste the skin for touch Reproductive system (breeding) The male reproductive organs, the testicles, lie in the scrotum behind the penis. The testicles produce sperm which are contained in the fluid semen. A tube passes from each testicle and joins to form a tube which runs down the centre of the penis. In the bird the testicles are inside the body. Reproductive and urinary organs of the male The female reproductive organ consist of two ovaries, one in each side of the lower abdomen. The ovaries produce eggs which pass into the uterus (or womb). Below the EAE I TEXTS, 2007-2008, p. 28 uterus is the vagina which opens to the outside surrounded by the vulva. After birth the young are fed on milk produced by the udder. Female reproductive and urinary system During mating (mounting) sperm passes from the male into the uterus and joins with the eggs there. When the sperm joins the egg it forms the embryo which develops into the young animal inside the uterus. Reproduction is controlled by hormones (chemical messengers) which are carried in the blood to the different organs. These hormones control: Puberty of the animal Production of eggs Birth Production of semen Development of the embryo Milk production Lympho-reticular system Lymph is a colourless fluid which passes out of the blood into a network of fine tubes called the lymphatic system. It passes through the lymph nodes, where germs are filtered out and killed, before it is returned to the veins. The lymph nodes and spleen also produce special blood cells which protect the body against disease. Sometimes when an animal is infected the lymph nodes become swollen and can be felt beneath the skin EAE I TEXTS, 2007-2008, p. 29 Post-Reading task: After studying this text, please explain briefly 2 of the following; write 1 or 2 paragraphs about 1 The various organs of the animal body. 2 The position of the main organs within the animal body. 3 The structure of the body systems. 4 How the systems work.

They are being seen. Billboards posted by Chipotle Grill state “Get antibiotics from your doctor, not your beef.” Similar Chipotle Grill billboards have been aimed at the poultry industry. Numerous food service companies have zeroed in on the public’s concern with antibiotic use in food animals and have developed their own antibiotic guidelines. Wendy’s, for example, has developed its own antibiotic use policies. Under “Managed Use,” Wendy’s policy states that “antibiotics used to treat food animals must only be administered by licensed veterinarians that have met all training and certification requirements.” Its EAE I TEXTS, 2007-2008, p. 31 “Human Health” guideline reads “Reduce overall antibiotic usage in food animals, especially when the class of antibiotics used is both a human and food animal medicine. Employ alternative therapies, or use antibiotics not used to treat human disease whenever possible.” Negative and frequently inaccurate headlines, editorials and messages on the Internet feed the frenzy. Concerned groups have been heard. On Feb. 8, 2007, Rep. Louise Slaughter (D-NY) sponsored H.R. 962, The Preservation of Antibiotics for Medical Treatment Act of 2007, which seeks to cut antibiotic resistance linked to the misuse of antibiotics in animal agriculture. Just four days later on Feb. 12, Sen. Edward Kennedy (D-MA) introduced the same bill in the Senate, S. 549. Other bills with the same title were introduced in previous Congressional sessions: 109th Congress, H.R. 2562; 109th Congress, S. 742; and 108th Congress, S. 1460. These bills failed to make it through the legislative process. The 2007 Bill would phase out the use as animal feed additives of antibiotics that are also important in human medicine, including penicillin, within two years. The bill also requires pharmaceutical companies manufacturing and marketing agricultural antibiotics to submit data on the quantity of drugs they sell, along with information on the claimed purpose and dosage for those drugs. The intention is to help public health officials track the implementation of the phase-out.

Your summary will be assessed by your teacher. Trees and forests can provide a range of benefits that are often complementary. Some of these benefits derive from green space in general, but forests may also offer unique opportunities. The social and environmental value of woodland and forest in Great Britain has been estimated to be worth up to £1 billion a year1. This POSTnote explores the issues surrounding the sustainable management of existing and new forest in the UK. Background Most of the UK was once covered by forest. Clearance for timber, fuel, and agriculture meant that by 1900, forest and woodland2 cover had fallen to about 5% of its land area. Timber demand during the First World War led to the creation of the Forestry Commission in 1919, with the aim of building up a strategic timber reserve. Large scale forest planting took place, mainly of productive non-native conifer species (such as Sitka spruce, native to North America) on land of marginal value for EAE I TEXTS, 2007-2008, p. 34 agriculture. One such example is Kielder Forest in Northumberland. The area of woodland has now risen to 11.6% of the UK land area (or 2.8 million hectares). The amount, type, and ownership of woodlands vary within the UK (Fig. 1). The majority of native trees, such as oak, are broadleaves (with flat leaves rather than needles), but some, such as Scots pine, are conifers. Woodland is considered ‘semi-natural’ if it is composed of locally native species. A small proportion of this woodland is classed as ‘ancient’, as it dates back to at least 1600 AD (or 1750 AD in Scotland3), and is often biodiverse and of cultural importance (an example being Sherwood Forest). Around 30% of forest is owned by the devolved governments and managed by the Forestry Commission or the Department of Agriculture and Rural Development (DARD) in Northern Ireland. However, only a small amount of this is semi-natural or ancient woodland. In recent decades, increased interest in nature conservation and recreation has led to a national and international policy move, away from a primary aim of timber production towards forestry that provides multiple benefits. ‘Sustainable forest management’ aims to provide social and environmental goods, to maintain an economically viable forestry sector and to protect these benefits for future generations.

Forest fires are an annual menace for Indonesia and the country's neighbors, who have grown deeply frustrated at the apparent lack of success in curbing the dry-season blazes and vast smoke clouds, or haze, that smothers the region. Apart from the health risks to millions of people and damage to the environment, the smoke also releases large amounts of carbon dioxide, fuelling global warming. The government has pledged to cut the number of fires by half. A 2004 law prohibits plantation companies from using fires, or any other means that cause environmental damage, to clear or cultivate land. Blazes have started flaring again since the end of June with the start of the dry season. Satellite images collected by the Forestry Ministry showed 124 "hot spots" in Riau on Sumatra island last week, more than other provinces in the country. Riau is just across the Strait of Malacca from Singapore and Malaysia. "The endless cycle of forest fires and forest destruction in Indonesia must now be seen as a global phenomenon because our country contributes a lot to climate change," Greenpeace Forest campaigner Hapsoro said in a statement. EAE I TEXTS, 2007-2008, p. 36 "Beyond the frequent lip service and rhetoric coming from officials whenever these fires flare up, the government must take bolder measures to prevent the problem from taking place," he said. "The government must strictly enforce laws against violators including oil palm companies and plantations which deliberately start these fires as part of their landclearing operations."
