alone and histopathological changes in human nasal mucosa. Although several studies have found changes, these cannot be associated with formaldehyde exposure alone and are confounded by other air contaminants. Boysenet al.(1990) found no significant histopathology differences in nasal mucosa of 37 workers and 37 controls exposed to 0.5 ppm to over 2 ppm of formaldehyde. Mutagenicity In vitro, formaldehyde is able to induce gene mutations and chromosomal aberrations in mammalian cells without (and also in presence of) external metabolic activation. DNA-protein crosslinks are a sensitive measure of DNA interaction by formaldehyde. In vivo, the overall evidence of available studies supports the conclusion that the genotoxic effects after exposure via relevant routes are limited to those cells which are in direct contact with formaldehyde and no effects are observed in distant-site tissues. This is consistent with
because there is not enough land mass to support the diversity of animals. The environment is very young due to the Ice Age, so there has not been enough time for such diversity to develop. The seasonal changes that occur across the country mean that the animals have less to eat. Since industrialization began in England in the mid eighteenth century, it has had a big impact on indigenous animal populations. Song birds in particular are becoming scarcer and habitat loss has affected larger mammalian species. Some species have however adapted to the urban environments, such as the Red Fox, which is the most successful urban mammal after the Brown Rat. Large mammals are not very numerous in GB. Many of the bigger species, such as the Grey Wolf and the Brown Bear were hunted to extinction many centuries ago. However, recently, many of these large mammals have been reintroduced to some areas of mainland Britain. The largest mammals that remain in Britain today are
throughout Finland from Norway and only reached the western coast less than three millennia ago. Oak and maple grows in nature only in the southern part of Finland. The Archipelago Sea, between the Gulf of Bothnia and the Gulf of Finland, is the largest archipelago in the world by number of islands; estimates vary between 20,000 and 50,000. Similarly, Finland has a diverse and extensive range of fauna. There are at least sixty native mammalian species, 248 breeding bird species, over seventy fish species and eleven reptile and frog species present today, many migrating from neighbouring countries thousands of years ago. Large and widely recognised wildlife mammals found in Finland are the Brown Bear (the national animal), Gray Wolf, elk and reindeer. Other common mammals include the Red Fox, Red Squirrel, and Mountain Hare. Some rare and exotic species include the flying
the cork-oak (Quercus suber), the holm oak (Quercus ilex), the Portuguese oak (Quercus faginea), and eucalyptus (Eucalyptus globulus). All are prized for their economic value. Laurisilva is a unique type of subtropical rainforest found in few areas of Europe and the world: in the Azores, and in particular on the island of Madeira, there are large forests of endemic Laurisilva forests (the latter protected as a natural heritage preserve). There are several species of diverse mammalian fauna, including the fox, badger, Iberian lynx, Iberian Wolf, wild goat (Capra pyrenaica), wild cat (Felis silvestris), hare, weasel, polecat, chameleon, mongoose, civet, brown bear (spotted near Rio Minho, close to Peneda- Gerês) and many others. Portugal is an important stopover for migratory birds, in places such as Cape St. Vincent or the Monchique mountain, where thousands of birds cross from Europe to Africa during the autumn or in the spring (return migration)

naturalists of the era. Though 19th century science is of only historical interest, his command of the English language, or at least of its Yankee version, is unimpeachable, so his definitions cannot be dismissed lightly. Melville somewhat famously asserts in the novel that the whale is a "spouting fish with a horizontal tail." His use of the word "fish" here, however, is not meant a denial of the mammalian characteristics of the order Cetacea, but rather simply as an ad hoc definition as an animal that dwells in the sea; however, he goes on to dismiss Linnaeus' classification as "humbug". He attempts a taxonomy of whales largely based on size, based on his assertion that other characteristics, such as the existence of a hump or baleen, make the classification too confusing. Borrowing an analogy from publishing and bookbinding, he divides whales into three
