Isingeniso ku-Tiger Salamanders

Ama-salamanders ama-Tiger angama-amphibians athakazelisayo ayingxenye yomndeni wakwa-Ambystomatidae. Zaziwa ngemigqa yazo ehlukile emnyama nephuzi, efana nephethini yengwe, yingakho igama lazo. Lezi salamanders zitholakala eNyakatho Melika futhi zitholakala ezindaweni ezihlukahlukene, kuhlanganise emahlathini, ezindaweni ezinotshani, ngisho eduze nezindawo zokuhlala zabantu. Ziyizilwane zasebusuku, ezisebenza kakhulu ebusuku, futhi ziyimigodi emihle kakhulu. Ama-salamanders ama-Tiger avumelana nezimo kakhulu futhi angahlala ezindaweni zombili zasemhlabeni nezasemanzini.

I-Anatomy ye-Tiger Salamanders

Ama-salamanders e-Tiger ane-anatomy eyingqayizivele eyenza akwazi ukuphila ezindaweni ezahlukene. Zinomzimba oyi-cylindrical onomsila omude, olinganiselwa kuma-intshi angu-6 kuya kwangu-8 ubude. Isikhumba sazo sibushelelezi futhi simanzi, okubenza bakwazi ukuphefumula ngesikhumba sabo. Zinemilenze emine enezinzipho ezikhule kahle, ezisiza ekugebeni nasekubambeni inyamazane. Amehlo azo mancane futhi ayindilinga, futhi anomlomo obanzi onamazinyo abukhali. Lawa ma-salamanders nawo anezindlala ezikhethekile emhlane wazo ezibizwa nge-parotoid glands, ezikhiqiza izinto ezinobuthi njengendlela yokuzivikela ezilwaneni ezidla ezinye.

Umjikelezo Wokuphila we-Tiger Salamanders

Umjikelezo wempilo wama-tiger salamanders uyathakazelisa impela. Iqala ngokuthi insikazi ibekela amaqanda emanzini njengamachibi noma emachibini. Lawa maqanda achanyuselwa abe izibungu, ezaziwa ngokuthi "ama-salamander tadpoles." Oshobishobi banamagill futhi bahlala emanzini, bedla izinto eziphilayo ezincane. Njengoba zikhula, ziba ne-metamorphosis, lapho zikhula khona amaphaphu nezitho. Lolu shintsho lubavumela ukuba bashiye amanzi futhi bahlale emhlabeni. Uma sezikhule ngokugcwele, ziba amasalamanders amahlosi amadala futhi zilungele ukugana nokuzalana.

Indawo yokuhlala kanye nokusatshalaliswa kweTiger Salamanders

Ama-salamanders angama-tiger angatholakala ezindaweni eziningi ezahlukahlukene eNyakatho Melika. Zigcwele kakhulu e-United States, eMexico naseCanada. Lawa ma-salamanders ayakwazi ukuzivumelanisa nezimo futhi angaphila ezindaweni ezihlukahlukene, kuhlanganise namahlathi, izindawo ezinotshani, ngisho nezingwadule. Zivame ukutholakala eduze nemithombo yamanzi, njengamachibi, amachibi, noma amaxhaphozi, lapho zizalela khona futhi zizalele amaqanda azo. Ama-salamanders ama-Tiger ayaziwa futhi ngokumba ngaphansi komhlaba, afune indawo yokukhosela phakathi nezimo zezulu ezimbi noma ukugwema izilwane ezidla ezinye.

Imikhuba Yokudla Neyokudla Ye-Tiger Salamanders

Ama-salamanders angama-tiger ayadla futhi anokudla okuhlukahlukene. Njengezibungu, zidla ngokuyinhloko izidalwa ezincane zasemanzini njengezinambuzane, ama-crustaceans, nezinhlanzi ezincane. Uma sebethole i-metamorphosis futhi sebebadala, ukudla kwabo kuyakhula ukuze kufake uhla olubanzi lwezisulu. Ama-salamanders ama-tiger amadala adla izinambuzane, izicabucabu, izikelemu zomhlaba, izilwane ezincelisayo ezincane, kanye nezinye izilwane ezihlala emanzini. Bangabazingeli abanekhono, basebenzisa umuzwa wabo obukhali wokuhogela nombono omuhle kakhulu ukuze bathole futhi babambe inyamazane yabo. Amazinyo azo abukhali kanye nemihlathi enamandla azivumela ukuba zidle inyamazane emikhulu kunosayizi wazo.

Ukukhiqiza kabusha kanye Nokuziphatha Kwama-Tiger Salamanders

Ama-salamanders e-Tiger abonisa ukuziphatha okuthakazelisayo kokuzala. Phakathi nenkathi yokuzalanisa, evame ukwenzeka entwasahlobo noma ekuqaleni kwehlobo, abesilisa bathuthela emachibini okuzalanisa futhi bakhiphe izingcingo zokuqomisana ezihlukile ukuze bahehe abesifazane. Lapho owesifazane esekhethe umngane womshado, bahlanganyela emdansweni wokuqomisana, ohlanganisa ukuzungezana nokuthintana. Iduna libe selibeka i-spermatophore, iphakethe lesidoda, phansi echibini, lensikazi eliqoqayo isebenzisa i-cloaca yayo. Ukuvundisa kwenzeka ngaphakathi, bese kuthi eyesifazane ibeke amaqanda ayo emanzini, lapho ekhula abe izibungu.

Izigaba Zokukhula Nentuthuko ze-Tiger Salamanders

Ngemva kokuchanyuselwa emaqandeni, ama-tiger salamanders aqala uhambo lwawo njengezibungu. Njengoba zikhula, kancane kancane zikhula izitho futhi zilahlekelwa ama-gill, zishintshe zibe izingane zasemhlabeni. Phakathi nalesi sigaba, ziyaqhubeka zikhula futhi zivuthwe zize zibe abantu abadala. Izinga lokukhula kwama-salamanders ehlosi lingahluka kuye ngezinto ezifana nokutholakala kokudla, izinga lokushisa, nezimo zendawo yokuhlala. Kuthatha iminyaka eminingana ukuthi bafinyelele ukuvuthwa kwezocansi, abanye abantu bathatha iminyaka emithathu noma emine ukuthi bakhule ngokugcwele.

Izinto Ezithinta Ukukhula Kwe-Tiger Salamanders

Ziningana izici zithonya ukukhula tiger salamanders. Ukutholakala kokudla okwanele kubalulekile ekukhuleni nasekuthuthukeni kwabo. Ukufinyelela ekudleni okuhlukahlukene, okuhlanganisa inyamazane ecebile ngamaprotheni, kukhuthaza ukukhula okusheshayo. Izici zemvelo ezifana nezinga lokushisa nomswakama nazo zidlala indima ebalulekile. Ama-salamanders ezindaweni ezifudumele avame ukukhula ngokushesha kunalawo asezifundeni ezibandayo. Ikhwalithi yendawo yokuhlala nokutholakala kwendawo yokukhosela efanelekile nakho kungaba nomthelela emazingeni okukhula. Ukwengeza, ukuncintisana ngezinsiza kanye nengcindezi ye-predation kungase kube nomthelela ekukhuleni, njengoba abantu ababhekene nokuncintisana okuphezulu noma ukudlwengulwa bangase banikeze amandla engeziwe ukuze baphile esikhundleni sokukhula.

Usayizi Omaphakathi wama-Adult Tiger Salamanders

Ama-salamanders ama-tiger amadala ayaziwa ngosayizi wawo omangalisayo. Ngokwesilinganiso, zikala phakathi kwamayintshi angu-6 kuya kwangu-8 ubude, kanti abanye abantu bafinyelela kumayintshi angu-14. Ukwakheka kwawo okuqinile komzimba kunomthelela ebukhulu bawo obukhulu. Kodwa-ke, kubalulekile ukuqaphela ukuthi kungase kube khona ukuhluka okuphawulekayo kosayizi phakathi kwabantu, kanti abanye bancane noma bakhudlwana kunosayizi ojwayelekile.

Ukuhlukahluka Kosayizi Phakathi Kwe-Tiger Salamanders

Ama-salamanders e-Tiger abonisa ukuhluka okukhulu kosayizi, ngaphakathi naphakathi kwabantu. Kunezici eziningana ezinomthelela kulokhu kuhlukahluka. Izici zofuzo zinendima, njengoba abanye abantu bengase bazuze izakhi zofuzo ezibabeka kusengaphambili ukuba bakhule babe bakhudlwana noma babe bancane. Izici zezemvelo nazo zinomthelela, njengoba ama-salamanders ezindaweni zokuhlala ezinothile angase akwazi ukuthola ukudla okwengeziwe, okuholela emasayizi amakhulu. Ukwengeza, ukuncintisana nokudlondlobala kungathonya usayizi, njengoba abantu ababhekene nokuncintisana okukhulu noma ingcindezi ye-predation bangase banikeze amandla engeziwe ekukhuleni noma ekusindeni, ngokulandelana.

I-Tiger Salamanders Ephula Irekhodi: Enkulu Kunabo Bonke Kwake Kwatholakala

Kuwo wonke umlando, kuye kwaba nemibiko yama-salamanders amakhulu kakhulu ehlosi. Enkulu kunayo yonke eyake yarekhodwa yatholakala eKansas, enesilinganiso esingama-intshi angu-16 ubude. Lesi sibonelo esimangalisayo sibonise ubukhulu bangempela obungaba khona balezi zilwane ezihlala emanzini nasemanzini. Kodwa-ke, abantu abanjalo abaphula amarekhodi abayivelakancane, futhi ama-salamanders amahlosi amaningi awela phakathi kosayizi omaphakathi. Ukutholwa kwalezi zibonelo ezingavamile zifakazela ukwehlukahlukana okumangalisayo nokuvumelana nezimo kwalezi zidalwa ezithakazelisayo.

Isiphetho: Ukuqonda Ukukhula Kwe-Tiger Salamanders

Ukukhula kwe-tiger salamanders kuyinqubo eyinkimbinkimbi ethonywa izici ezihlukahlukene, okuhlanganisa ufuzo, imvelo, nokutholakala kwezinsiza. Lezi zilwane ezihlala emanzini zidlula umjikelezo wokuphila othakazelisayo, zisuka ezibungwini zasemanzini ziye kubantu abadala basemhlabeni. Ukuqonda izici ezithinta ukukhula nokuthuthuka kwabo kunikeza imininingwane ebalulekile ku-ecology yabo kanye ne-biology. Nakuba ama-salamanders amahlosi aziwa ngosayizi wawo omangalisayo, abonisa ukuhluka okuphawulekayo ngosayizi phakathi kwabantu kanye nenani labantu. Kungakhathaliseki ukuthi zinkulu noma zincane, lezi zidalwa ziyaqhubeka nokusidonsa ngekhono lazo elimangalisayo lokuzivumelanisa nezimo futhi zichume ezindaweni ezihlukahlukene eNyakatho Melika.
