Pravasam is a 2008 Malayalam novel written by M. Mukundan.
 According to the author, the novel is an attempt to re-define nostalgia which is thought to be the essence of life of non-resident Malayalis and to pay respect to hundreds of thousands of Malayalis living as non-resident Keralites in different parts of the world.
 It is a novel that travels through generations.
 It depicts a clear picture of the life stories of various persons living in various parts of the world as non-resident keralites.
 It explains us about the different kinds of feelings of various kinds of people who had left their homeland for various reasons.
 These reasons include the emigration for the sake of seeking a better profession, for studies, for getting a better class of living and so on.
 But almost all of them dreams of returning to their homeland one day and enjoying the homeliness.
 One of the issues the books addresses is the question of cultural identity of the Malayali.
 A notable fact about the novel is that renowned Malayalam author S. K. Pottekkatt is a major character in the narrative.
 In the beginning, the narration is given such that, story is told by Pottekkatt and after his death, it was completed by Mukundan.
 Even, the narrator, himself is a non-resident keralite and has a lot of experiences to share with the readers.
 Whatever amenities the emigration life had provided them, each one of them, deep in their mind had a strong desire to come back to their native land one day.
 This uncontrolled emotions and sentiments of malayalis towards their homeland is clearly illustrated in the story.
The Indian aurochs ("Bos primigenius namadicus") is a subspecies of the extinct aurochs.
 It is considered as the ancestor of the zebu cattle, which is mainly found in southern Asia and has been introduced in many other parts of the world, like Africa and South America.
 In contrast, the taurine cattle breeds, which are native to Europe, the Near East, and other parts of the world, are descendants of the Eurasian aurochs ("Bos primigenuis primigenius").
 The Indian aurochs disappeared in the Holocene, probably around 2000 BC.
Olsynium (huilmo in Chile; formerly part of "Sisyrinchium") is a genus of summer-dormant rhizomatous perennials in the iris family, native to sunny hillsides in South America and western North America.
Poa pratensis, commonly known as Kentucky bluegrass, smooth meadow-grass, or common meadow-grass, is a perennial species of grass native to practically all of Europe, northern Asia and the mountains of Algeria and Morocco.
 Although the species is spread over all of the cool, humid parts of the U.S., it is not native to North America.
 Early European colonists brought seed of Kentucky bluegrass to the New World in mixtures with other grasses.
 "Poa pratensis" forms a valuable pasture plant, characteristic of well-drained, fertile soil.
 It is also used for making lawns in parks and gardens and is common in cool moist climates like the northeastern United States.
 When found on native grasslands in North America, however, it is considered an unwelcome exotic plant, and is indicative of a disturbed and degraded landscape.
Bidens pilosa is a species of flowering plant in the aster family.
 It is native to the Americas but it is known widely as an introduced species of other regions, including Eurasia, Africa, Australia, and the Pacific Islands.
 It is a tall branched weed with thin yellow flowers that develop into a cluster of barbed seeds.
 Its many common names include black-jack, beggar-ticks, cobbler's pegs, and Spanish needle.
 The seeds are like short, stiff hairs.
 They get stuck in feathers, fur, or socks, etc.
 This bur is widespread throughout the warmer regions of the world.
 Its little black seeds hook onto clothes or horses and thereby the bur spreads itself around.
 It is susceptible to hand weeding if small enough, even then must be bagged, and thick mulches may prevent it from growing.
 Each seed has two to four barbed spines.
 A weed of gardens, woodlands, and waste areas, a person who brushes against it will end up covered in the burs and need to pick them off one by one.
 Although this plant is considered a weed in some parts of the world, in other parts it is a source of food or medicine.
 For example, it is reportedly widely eaten in Africa, and in Vietnam, during the Vietnam War soldiers adopted the herb as a vegetable, which lead to it being known as the "soldier vegetable".
Exploitation colonialism is the national economic policy of conquering a country to exploit its natural resources and its native population.
 The practice of exploitation colonialism contrasts with settler colonialism, the policy of conquering a country to establish a branch of the metropole (Motherland), and for the exploitation of its natural resources and native population.
 A colonialist power pursues settler colonialism to relieve the pressures of over-population upon the economy and the national territory of the motherland, and to extend its territory and culture by reproducing its society in other parts of the world.
 A reason for which a country might practice exploitation colonialism is the immediate financial gain produced by the low-cost extraction of raw materials by means of a native people, usually administered by a colonial government.
The Eurasian otter ("Lutra lutra"), also known as the European otter, Eurasian river otter, common otter, and Old World otter, is a semiaquatic mammal native to Eurasia.
 The most widely distributed member of the otter subfamily (Lutrinae) of the weasel family (Mustelidae), it is found in the waterways and coasts of Europe, many parts of Asia, and parts of northern Africa.
 The Eurasian otter has a diet mainly of fish, and is strongly territorial.
 It is endangered in parts of its range, but recovering in others.
Centaurea cyanus, commonly known as cornflower or bachelor's button, is an annual flowering plant in the family Asteraceae, native to Europe.
 In the past it often grew as a weed in cornfields (in the broad sense of the word "corn", referring to grains, such as wheat, barley, rye, or oats), hence its name.
 It is now endangered in its native habitat by agricultural intensification, particularly over-use of herbicides, destroying its habitat.
 It is also, however, through introduction as an ornamental plant in gardens and a seed contaminant in crop seeds, now naturalised in many other parts of the world, including North America and parts of Australia.
Eriobotrya is a genus of flowering plants, mostly large evergreen shrubs and small trees in the family Rosaceae, native to woodland in the Himalayas and East Asia.
 The loquat, "E. japonica", is grown for its edible fruit.
Brassica elongata, the elongated mustard or long-stalked rape, is a species of the mustard plant that is native to parts of Central Europe, Eastern Europe, the Balkan Peninsula, the Caucasus, Morocco and parts of Central Asia.
 Through plant invasion this species has become naturalized in many other parts of the world.
 Some of these naturalized regions include South Africa, North Western Europe, Australia and North America.
 Given the wide range of climate and ecological conditions of these regions, "B. elongata" has been able to disrupt the ecosystems of their native plant habitats and has been label as an invasive species in many of its naturalized zones.
 In North America, this species is often found as a roadside weed in the southwestern states, particularly in the state of Nevada.
 Studies allude that the Cruciferae might have migrated through the Bering land bridge from what is now Central Asia.
 Commonly known as the long-stalked rape or as "langtraubiger Kohl " in German, this species is a close cousin to "Brassica napus" (rapeseed) and a secondary genetic relative to "B. oleracea" (kale).
 As a close genetic species of the rapeseed, the long-stalked rape has one of the highest counts of accumulated polyunsaturated linoleic and linolenic acid.
 Both compounds are heavily used to manufacture vegetable oils.
 "Brassica elongata" has the propagative potential of turning into a horticultural product from what is currently a noxious weed.
