Akaatsia (Acacia) on mitmekesine, väga laia levikuga puude ja põõsaste perekond liblikõieliste sugukonnast. Robiinia (Robinia) ehk valge- ehk ebaakaatsia ei kuulu akaatsiate hulka. Süstemaatika ja evolutsioon ● Akaatsialiike on praegu teada umbes 1350 ● Osade liikide jaoks on siiski mingil määral kasutusel teine perekonnanimi Racosperma. ● Kaheksakümnendatel lepiti kokku jagunemises kolmeks rühmaks (alamperekonnaks), kuid laialt neid kasutusele ei võetud. ○ Acacia (-alamperek. Acacia) ○ Senegalia (-alamperek. Aculeiferum) ○ Racosperma (-alamperek. Phyllodineae) Hiljutised uurimused on välja selgitanud umbes viie üksuse (perekonna või alamperekonna) olemasolu. Need on: ● Acacia (= Acacia): 163 liiki ● Senegalia (= Aculeiferum): 203 liiki ● Racosperma (= Phyllodineae): 961 liiki ● Acaciella (= Aculeiferum sektsioon Filicinae): 15 liiki ● "perekond x" (= veel nimetamata alamperekond, kuhu
Grazing animals can have a more direct effect on woody plants by the browsing of palatable woody species. There is evidence that unpalatable woody plants have increased under grazing in savannas. Grazing also promotes the spread of weeds in savannas by the removal or reduction of the plants which would normally compete with potential weeds and hinder establishment. In addition to this cattle and horses are implicated in the spread of the seeds of weed species such as Prickly Acacia and Stylo. These alterations in savanna species composition brought about by grazing can alter ecosystem function, and are exacerbated by overgrazing and poor land management practices. Introduced grazing animals can also affect soil condition through physical compaction and break-up of the soil caused by the hooves of animals and through the erosion effects caused by the removal of protective plant cover. Such effects are most likely to occur on land subjected to repeated and heavy grazing

Suur Liivakõrb 1. Kõrbe asend Suur Liivakõrb asub Austraalia madril ja paikneb selle loodeosas. Lõunas piirneb Gibsoni kõrbega, kirdes Kimberley lavamaaga ja loodes India ookeaniga. Kõrb paikneb ligikaudu 20-30 S ja 110-140 E. Kõrb asub troopilises kliimavöötmes. 2. Kõrbe suurus ja ulatus Suure Liivakõrbe suurus on 284993 km2 ning sellise pindalaga hõlmab ta umbes kahekümnendiku Austraalia pindalast(7,7 mln km2 ). 3. Kliimatingimused ja tekkepõhjused Suure Liivakõrbe keskmine sademetehulk on 250 mm aastas, Kimberely lavamaa läheduses 300 mm aastas. Suviti (septembrist maini) on temperatuurid kõrged, keskmiselt 37 ja 38 kraadi ümbruses. Talv on lühike, mai algusest augusti lõpuni. Talvel jääb temperatuur 25 ja 30 kraadi vahele. Gibsoni kõrbe lähedastel aladel võib esineda paar korda aastas härmatis. Suur Liivakõrb asub pöörijoonte piirkonnas. Seal on asetsevad las...

In the very east there are wet forests that occupy the space between the Great Dividing Range and the eastern coast. The wet forests give place to beautiful grasslands with some trees called the savannas. Farther west the trees disappear and the bushlands begin. The real desert occupies the centre of the Western Plateau. In the very southwest there are thin forests of evergreen trees. Most of Australian trees are kinds of eucalyptus (or gum tree to Australians) and acacia (wattle of Australians). Eucalyptuses give the people timber and eucalyptus oil. Of 600 kinds of acacias the golden wattle, the national flower of Australia, is the best known. Of other trees there grow bottle trees in the savannas, tree ferns in the tropical forests and many others. Lakes Australia has much underground water. There are only few lakes which are full of water only after it rains. The biggest lake is Lake Eyre which is a salt lake.

coast. Westward from the Great Dividing Range the wet forests give place to beautiful grasslands with some trees . These grasslands are called the savannas (2.). Farther west the trees disappear and the bushlands (3.) begin. The real desert (4.) occupies the centre of the Western Plateau. In the very southwest there are thin forests of evergreen trees (5.). Most of Australian trees are kinds of eucalyptus trees (or gum trees to Australians) and acacia ( wattle to Australians). Eucalyptus trees are found everywhere in Australia. There are many kinds of them and they greatly differ in size. One kind, the great mountain ash, can grow to 120 metres and it grows in the wet forests in the eastern part of the continent.These strong trees do not die when there are forest fires. Some other kinds are small bushes in the semi-deserts.Eucalyptuses give the local people timber and eucalyptus oil.

So, the rainforests occupy the space between the Great Dividing Range and the eastern coast and also the northern coast. In the west they give place to beautiful grasslands with some trees called the savannas. Further west the trees disappear and the savannas are replaced by the bush lands. The real desert occupies the centre of the Western Plateau and in the very south- west there are thin forests of evergreen trees. Most of the Austrian trees are various kinds of eucalyptus and acacia. Some eucalyptuses are small bushes in the semi deserts, some are the main trees in the savannas, but the biggest eucalyptuses grow as tall as hundred metres. Eucalyptuses give the people timber and eucalyptus oil. Of 600 kinds of acacias, the golden wattle is the best know because it is the national flower of Australia. Of the other trees there are bottle trees in the savannas and tree-ferns in the tropical forests and many others.
Australia Australia is the smallest continent in the world. It is 7.6 million square kilometres big. It is often called the island continent because it is rather small for a continent and very big for an island. There are only five countries bigger than Australia in the World. There are five states in the mainland. Tasmania is also considered as a state so there are six states. The Northern Territory and Canberra are also independent but they are not states. Canberra is the capital of Australia and it is situated between Sydney and Melbourne because both of these cities wanted to be the capital. The population is about 19 million people and growing. New South Wales is the most populated state and Victoria is the most densely populated state. The national language is English. It is English because British settlers came to live in Australia in the past and they brought conv...

Tallinna 21. Kool Mika Waltari ,,Sinuhe'' Raamatu analüüs Tallinn 2011 Esimene raamat: KÕRKJALOOTSIK Teistest erinev Sinuhe elas ruumikas ja avaras majas koos vaeste Senmuti ja tema naise Kipa ''pojana''. Senmut tahtis, et ta poeg saaks Amoni templi suurde Elu majja õpilaseks ning kasututas selleks ära vana tuttavat Ptahorit, kes töötas kuningliku koljuavajana. Senmut jagas Sinuhele palju õpetusi. Sinuhe sai endale põneva kaaslase Onegi koolist, poisi nimega Thotmes, kellele meeldis joonistada. · Vaarao (lk 7) sõna ''vaarao'' oli algselt kasutusel kui kuninglik palee. Alates 18. Dünastiast hakkasid egiptlased oma kuningaid nimetama vaaraodeks. Esimene kuningas, keda on teadaolevalt nõnda nimetatud, oli Thutmosis III. Tänapäeval nimetatakse vaaraodeks kõik...
