Intshayelelo kwii-Alligators zaseMelika

Iingwenya zaseMelika, ngokwesayensi ezaziwa ngokuba yi-Alligator mississippiensis, zizirhubuluzi ezinkulu ezihlala kumazantsi mpuma eUnited States. Ezi zidalwa zinamandla zaziwa ngamandla azo amangalisayo kunye nobukho obumangalisayo. Ngemizimba yazo exhobileyo, imihlathi eyomeleleyo namazinyo abukhali, ngokufuthi zigqalwa njengezinto eziphilayo zamaxesha angaphambi kwembali. Iingwenya zaseMelika kudala zinomdla kwizazinzulu kunye nabathandi bezilwanyana zasendle ngokufanayo, kwaye ukukhetha kwabo indawo yokuhlala ibe sisihloko sophando oluninzi kunye neengxoxo.

Ukhetho lweNdawo yokuHlala yeengwenya zaseMelika

Iingwenya zaseMelika ikakhulu zihlala kwindawo ezinamanzi acocekileyo njengemigxobhozo, imigxobhozo kunye namachibi. Ezi ndawo zokuhlala zibonelela ngeemeko eziyimfuneko ukuze ziphile, kuquka imithombo yokutya eyaneleyo, amaqondo obushushu afanelekileyo, kunye neendawo ezifanelekileyo zokuzalela. Iindawo ezihlala emanzini acocekileyo zikwabonelela ngokhuseleko kumarhamncwa kunye nendawo eyaneleyo yokuba ezi zidalwa zisemhlabeni zimisele imimandla yazo.

Ukulungelelaniswa kwe-American Alligators

Nangona iindawo zokuhlala ezihlala emanzini acwengileyo zikhethwa, iingwenya zaseMelika zibonakalise ukuba zizidalwa eziguquguqukayo ngokuphawulekayo. Ziye zabonwa kwiindawo ezahlukeneyo zokuhlala, kuquka imilambo, amachibi, kunye nemisele. Oku kulungelelaniswa bubungqina bokukwazi kwabo ukulungelelanisa kwiimeko eziguqukayo kunye nokuhlola indawo entsha.

Indima Yetyuwa kwiiNdawo ze-Alligator

Ityuwa, okanye ukuxinana kwetyuwa emanzini, kudlala indima ebalulekileyo ekuqinisekiseni ukuba iingwenya zaseMelika zingahlala kwindawo ethile yokuhlala. Ngelixa zifumaneka ikakhulu kwiindawo zokuhlala zamanzi acwengileyo, ziye zabonakalisa unyamezelo oluthile lwamanzi anebrackish, angumxube wamanzi acocekileyo kunye netyuwa. Nangona kunjalo, ukukwazi kwabo ukuhlala ngokupheleleyo kwiindawo ezihlala emanzini anetyuwa kuye kwaba ngumbandela wengxoxo phakathi kwabaphandi.

Ngaba ii-Alligators zaseMelika ziyakwazi ukusinda kumanzi anetyuwa?

Ngokuchasene nenkolelo ethandwayo, iingwenya zaseMelika azikufanelanga ukuhlala kwindawo enetyuwa. Ukuziqhelanisa nokuziphatha kwabo kunye neendlela zokuziphatha azilungiselelwanga imingeni ebangelwa ngamanqanaba aphezulu etyuwa. Ngelixa bekwazi ukunyamezela ukuvezwa kancinci kumanzi anetyuwa, ukuba sesichengeni ixesha elide kunokuba neziphumo ezibi kwimpilo yabo nasekuphileni kwabo.

Ukunyamezelwa kwamanzi etyiwa kwii-Alligators zaseMelika

Uphononongo lubonise ukuba i-alligators yaseMelika inokunyamezela amanqanaba aphantsi etyuwa ixesha elifutshane. Ziye zabonwa kwiindawo ezihlala amanzi anebrackish, apho ityuwa iphantsi kuneendawo ezihlala amanzi anetyuwa ngokupheleleyo. Nangona kunjalo, ukunyamezela kwabo kumanqanaba aphezulu etyuwa, njengalawo afumaneka kulwandle oluvulekileyo, kulinganiselwe.

Utshintsho lwePhysiological kwii-Alligators kumanzi etyuwa

Xa zibonakaliswe kumanzi etyuwa, ii-alligators zaseMelika zifumana utshintsho kwi-physiological ukubanceda ukuba bajamelane noxinzelelo lwe-osmotic. Olu tshintsho lubandakanya ukunyuka kwetyuwa ngokunyuka kwamadlala akhethekileyo kwiilwimi zabo kunye nokunciphisa ukulahlekelwa kwamanzi ngesikhumba sabo. Nangona kunjalo, oku kuziqhelanisa akwanelanga ukubavumela ukuba baphumelele kwiindawo zokuhlala ezinamanzi anetyuwa ixesha elide.

Ukuziphatha kweengwenya zaseMelika kumanzi anetyuwa

Xa i-alligators yaseMelika idibana namanzi anetyuwa, ngokuqhelekileyo ibonisa ukuziphatha kokuphepha. Baza kufuna imithombo yamanzi ahlaziyekileyo ukuba basele kwaye bahlambe ityuwa emizimbeni yabo. Ukuba amanzi acwengileyo akafumaneki lula, banokunciphisa ukuchanabeka kwabo kumanzi anetyuwa okanye bafudukele kwezinye iindawo ezilungele ukuphila kwabo.

Imingeni eJongana neengwenya kwiindawo ezihlala amanzi etyuwa

Iindawo ezihlala emanzini anetyuwa zinika imingeni emininzi kwiingwenya zaseMelika. Ukunyuka kwetyuwa kunokuphazamisa ibhalansi yabo yamanzi, okukhokelela ekuphelelweni kwamanzi kunye nokungalingani kwe-electrolyte. Ukunqongophala kweendawo ezifanelekileyo zokuhlala iindlwane kunye namaxhoba akhoyo anokuthintela impumelelo yawo yokuzala kunye nokukhula kwabantu ngokubanzi. Ngaphaya koko, ukukhuphisana neentlobo ezilungelelaniswe namanzi etyuwa kunokunciphisa ngakumbi amandla azo okuphila kwindawo enjalo.

Iindawo ezingaseluNxwemeni zifanelekile kwii-Alligators e-US

Nangona ii-alligators zaseMelika zingenakuphumelela kwiindawo zokuhlala zamanzi etyuwa, iindawo ezithile zonxweme ezinamanzi ane-brackish zinokubonelela ngeemeko ezifanelekileyo zokuphila kwazo. Umzekelo, imigxobhozo kunye namachweba aseGulf Coast kunye ne-Everglades eFlorida anika umxube wamanzi ahlaziyekileyo kunye namanzi anetyuwa anokuxhasa ingwenya. Ezi ndawo zisebenza njengemimandla ebalulekileyo yenguqu apho iingwenya zinokufumana izixhobo eziyimfuneko kwaye zilungelelanise amanqanaba ahlukeneyo etyuwa.

Iinzame zoLondolozo lweengwenya kumanzi anetyuwa

Iinzame zolondolozo zibalulekile ekukhuseleni iingwenya zaseMelika kumanzi amatsha kunye neendawo zokuhlala ezinamanzi anebraki. Oku kuquka ukulondolozwa kwendawo yokuhlala, ukulawulwa kokuzingela nokuzingelwa ngaphandle kwemvume, kunye nokufundisa uluntu ukukhuthaza ukuhlalisana nezi zidalwa zibalaseleyo. Ukongezelela, ukubeka iliso kwimpembelelo yokutshintsha kwemozulu ekungeneni kwamanzi etyuwa kwiindawo zokuhlala zamanzi ahlambulukileyo kubalulekile ukuqinisekisa ukusinda kwexesha elide kwii-alligators zaseMelika.

Ukuqukumbela: Amandla eengwenya kwiindawo zokuhlala zamanzi etyuwa

Ngelixa ii-alligators zaseMelika ziqhelaniswe ikakhulu neendawo zokuhlala zamanzi acocekileyo, ziye zabonisa unyamezelo olulinganiselweyo lwamanzi amtyuba. Nangona kunjalo, iindawo zokuhlala zamanzi anetyuwa ngokupheleleyo zenza imingeni ebalulekileyo yokuphila kwazo. Utshintsho lomzimba kunye nohlengahlengiso lokuziphatha olubonakaliswe ziingwenya zaseMelika ekuphenduleni ukuvezwa kwamanzi etyuwa akwanelanga ukuxhasa abantu abakhulayo kwiindawo ezinjalo. Iinzame zolondolozo kufuneka zigxininise ekukhuseleni iindawo zazo zokuhlala ezikhoyo kunye nokuqinisekisa ukufumaneka kweendawo ezifanelekileyo zenguqu apho iingwenya zikwazi ukuziqhelanisa nokutshintsha kwamanqanaba etyuwa. Ngokuqonda nokuhlonipha ukukhethwa kwendawo ezihlala kuzo ezi zidalwa zibalaseleyo, sinokuqinisekisa ubukho bazo obuqhubekayo kwindawo eziyibiza ngokuba likhaya.
