Mangroves - Abuur gaarka ah ee dabiiciga ah

Mangroves - a dhirta canbaha kaymo, degeen on soohdimaha kulaylaha iyo dadka fareen iyo ku habboon nolosha sbarmuutada, si joogto ah iyo socodka. Waxay kor u koraan ilaa 15 mitir oo ay leeyihiin a xididdada nooc, malana stilted (geedka qaadaa biyaha ee kor ku xusan) iyo neefsashada (pneumatophores) ridday ciidda, sida caws iyo ahmiyadda oxygen.

dhirta tiro yar ayaa ka badbaaday in biyo cusbo ah, laakiin tani ma khusayso mangroves ah. Waxay yeelatay habab shaandhaynta. Biyaha la nuugo xidido, waxa ku jira in ka yar 0.1% cusbo. cusbo soo hartay kala caleemo iyada oo bir sheet gaar ah la xirrira kiristaalo cad dushiisa.

Ciidda kaas oo u koraan mangroves, mar walba oo biyo ah, ma jiro oksijiin ku filan. Under xaaladaha sida, bakteeriyada anaerobic go'doonsan nitrogen, phosphates, birta, methane iyo sulfides t. D., Abuuritaanka geedaha ur ku waani. La'yahay xididdada oxygen, sida la sheegay, waxa laga soo qaatay hawada, iyo nafaqo - ciidda.

The caleemaha dhirta, kuwaas oo - adag, saan, succulent, cagaaran dhalaalaya. Iyada oo la tixgelinayo salinity oo ka mid ah ciidda iyo la'aanta biyo nadiif ah, ay ku habboon khasaaraha qoyaan kooban. Leaves qabsato kartaa heerka uu furitaanka stomatal galeen sarrifka gaaska ee geedi socodka of photosynthesis, iyo isku shaandheyn, si looga fogaado in ay fallaaraha qorraxda kulul.

Mangroves koraan zones, kuwaasoo mid walba uu u badnaayeen noocyada qaarkood. Tan waxa u sabab ah inta jeer iyo muddada daadadka, nooca substrate biyaha (bacaadka ah ama dhoobo), badda iyo cusub by (in estuaries). Ku baayacmushtara safka hore Rhizophora dhex leh alwaax dhiig-cas, midabka ah ee wixii la goostay by content sare ee tannin. noocyada Tani waa biyo ah oo ku saabsan 40% waqtiga. Tan waxa la Avicenna lagulyarii et al.

Sidee baqaayo geed is mangrove, iyo midhaha (miraha) waxa aan caadi ahayn. Waxay lagu daboolay maro pneumatic, kaas oo ay awoodaan in ay ku dabaalan waqti cayiman, badalka ay cufnaanta, haddii loo baahdo. mangroves badan - "viviparous." miraha ay yihiin aan loo kala geedkii ka soo biqlo. Seedling ama guuro gudaha midhaha ama miro dusha loo marayo. By waqtiga uu diyaar u yahay inuu ku kori madax banaan ku shaqeeya by photosynthesis ahaa.

Barkinta ka geed (sida caadiga ah inta lagu guda jiro hir low), seedling uu hoos u dhaco oo si degdeg ah go'an ee ciidda. Ama kaxaystay by biyaha, waxaana suurto gal meel fog ka hufan. Isagu waa sidaas tenacious in uu sugi karo daqiiqad goor wanaagsan inuu sannad ah in ay qaataan xididka.

Mangroves adeego sidii ay magan galaan iyo Habitat for organisms badan. Algae, oysters, barnacles, buushka, bryozoans lagama maarmaan ah in lifaaq wax sifeynta ee cuntada. xididdada Multiple aad u fiican for this. kalluunka Tropical, cayayaanka, masaska waxaa laga helaa biyaha u dhow nidaamka xididka. laamaha geedka degeen hummingbirds, markab, Sareynta, gulls, iyo shimbiraha kale.

Mangroves, si deg deg ah la xirrira jiqda, ilaaliyaan xeebta ka nabaad by hirarka badda. Waxay ayaa ku dhow inay badda, guuleysto dib goobo cusub. xididdada dadku iskumaran xajin sababay waxyabaha, kor u qaadida dheecaan of ciidda. dadka deegaanka isticmaalaa dalka dib, abuurista leexsan a Timir qumbaha, liinta iyo dalagyo kale.
