Intshayelelo yamasele eglasi

Amasele eglasi liqela elilodwa lezilwanyana ezihlala emanzini nasemanzini ezifumaneka kuMbindi nakuMzantsi Melika. Zithiywa ngesikhumba sazo esiguquguqukayo, esivumela amalungu azo angaphakathi ukuba abonakale ngaphandle. La masele aziwa ngendlela aphila ngayo arboreal, ahlala ikakhulu emithini nasemahlathini kufutshane nemilambo kunye nemilambo. Amasele eglasi angawosapho lweCentrolenidae kwaye ahlulahlulwe abe ziindidi ezininzi, ngalinye lineempawu zalo ezahlukileyo.

Ukuveliswa kwakhona kwiGlass Amasele: Isishwankathelo

Ukuveliswa kwamasele eglasi yinto enomdla kwibhayoloji yawo. Njengazo zonke ii-amphibians, amasele eglasi azalana ngokwesondo, kunye nabantu abahlukileyo abangamadoda nabasetyhini. Nangona kunjalo, indlela ethile yokuzala esetyenziswe ngamasele eglasi ibe ngumxholo wophando lwesayensi kunye nengxoxo.

Ukuqonda iindlela zokuzala kwizilwanyana

Iindlela zokuzala kwizilwanyana zingahlelwa ngokubanzi zibe ngamaqela amabini aphambili: ukubeka iqanda kunye nokuzalwa okuphilayo. Ukubekwa kweqanda yeyona ndlela ixhaphakileyo, ebonwa kuninzi lwezilwanyana eziphila emhlabeni nasemanzini, izirhubuluzi, kunye neentlobo ezininzi zeentlanzi. Ukuzala okuphilayo, kwelinye icala, yinto enqabileyo ngentelekiso efumaneka kumaqela ambalwa ezilwanyana, njengezilwanyana ezanyisayo kunye nezinye ezirhubuluzayo.

UkuZalwa okuPhila kuthelekiswa noKubeka Iqanda: Ingxaki yendaleko

Ukhetho lwendaleko phakathi kokuzalwa okuphilayo kunye nokubekwa kweqanda luphenjelelwa zizinto ezahlukeneyo, kubandakanywa imiqobo yendalo, impumelelo yokuzala, kunye nokhathalelo lwabazali. Indlela nganye ineengenelo zayo kunye nokungalungi kwayo. Ngokomzekelo, ukubeka iqanda kuvumela ukwanda kwemveliso yenzala kodwa kubeka amaqanda kwizilwanyana ezidliwayo kunye nokuguquguquka kokusingqongileyo. Ukuzalwa okuphilayo, kwelinye icala, kunika ukhuseleko olungcono lwabazali kodwa kunciphisa inani lenzala eliveliswayo.

Amasele eglasi: Ukubeka amaqanda okanye ukuzala ukuze uphile umncinci?

Amasele eglasi aziwa ngendlela yawo yokuzala eyodwa yokubeka amaqanda kunokuba azale ukuhlala emncinci. Iimazi zibeka amaqanda azo kumagqabi angaphezu kwamanzi, njengemilambo okanye amachibi. Le ndlela yokuziphatha ivumela iimbumba ezikhulayo ukuba ziwele emanzini xa ziqanduselwa, apho ziqhubeka nokukhula kwazo.

Ukuphonononga i-Reproductive Anatomy yeGlass Frogs

I-anatomy yokuzala yamasele eglasi inika ingqiqo kwindlela yokubeka iqanda. Iimazi zinesakhiwo esikhethekileyo esibizwa ngokuba yi-cloaca, esebenza njengendawo eqhelekileyo yokukhupha kunye nokuzala. Iinkunzi zona zinamasende amade kunye nepere yamalungu okugcina amadlozi abizwa ngokuba yi-vasa deferentia. Ezi mpawu ze-anatomical ziyimfuneko ekuchumeni ngempumelelo ngexesha lenkqubo yokubeka iqanda.

Ukubeka Iqanda: Indlela eqhelekileyo yokuZala kwii-Amphibians

Ukubekwa kweqanda yeyona ndlela ibalaseleyo yokuzala phakathi kwezilwanyana ezihlala emanzini nasemanzini, kuquka uninzi lweentlobo zamasele. Ibandakanya ukubekwa kwamaqanda kwiindawo ezahlukeneyo zokuhlala, njengendawo yamanzi, inkunkuma yamagqabi, okanye imingxuma engaphantsi komhlaba. Amaqanda ngokuqhelekileyo ajikelezwe yi-gelatinous matrix enika ukhuseleko kunye nomswakama ngexesha lophuhliso. Le ndlela ivumela ukuchumisa ngaphandle, apho amadoda akhupha amadlozi emaqandeni emva kokuba ebekwe.

Ulungelelwaniso lweNzala ekhethekileyo yamasele eglasi

Amasele eglasi atshintshe indlela eyodwa yokuzala kwindlela aphila ngayo arboreal. Ngokubeka amaqanda abo emagqabini ngaphezu kwemithombo yamanzi, banciphisa umngcipheko wokuhlaselwa kwaye banikeze iimeko ezifanelekileyo zophuhliso lwabo. Ubume obungafihliyo bamaqanda buvumela abaphandi ukuba bajonge iimbumba ezikhulayo kwaye bafunde ukukhula kunye nokuziphatha kwazo kwimeko yendalo.

Ukuzalwa okuphilayo: Into enqabileyo kwi-Amphibians

Ngelixa uninzi lwama-amphibians luxhomekeke ekubekeni kweqanda, iintlobo ezimbalwa ziye zavelisa amandla okuzala ukuze ziphile zincinci. Nangona kunjalo, ukuzalwa okuphilayo kwii-amphibians kunqabile kakhulu, kunye neentlobo ezimbalwa kuphela ezaziwayo ukubonisa esi sicwangciso sokuzala. Izizathu zoku kunqabile aziqondwa ngokupheleleyo, kodwa zinokunxulumana nemingeni yokubonelela ngesondlo esaneleyo kunye neoksijini ekuphuhliseni iimbumba ngaphakathi komzimba wesetyhini.

Ukhathalelo lukaMama kumasele eglasi: Ukukhulisa inzala

Emva kokuba amaqanda eglasi eqanduselwe aze awele emanzini, amasele ayinkunzi adlala indima ebalulekileyo ekunyamekeleni inzala yawo. Ziyawakhusela amaqanda kwaye ziqinisekisa ukuba aphila ngokuwagcina efumile kwaye ewakhusela kumarhamncwa. Olu khathalelo lukatata lubalulekile kuphuhliso oluyimpumelelo lwetadpole de zibe ngamasele amadala.

Izinto eziphembelela iindlela zokuzala kwiGlasi yamasele

Izinto ezininzi zinefuthe kwiindlela zokuzala ezibonwa kumasele eglasi. Iimeko zokusingqongileyo, kuquka ubushushu, ukufuma, nokufumaneka kweendawo ezifanelekileyo zokuzalela, zidlala indima ebalulekileyo ekubumbeni iindlela zabo zokuzala. Ukongeza, uxinzelelo lwe-predation, ukhuphiswano lwemithombo, kunye nezinto zofuzo zinokuthi zibe negalelo ekwamkelweni kokubeka iqanda njengeyona ndlela ithandwayo yokuzala kumasele eglasi.

Ikamva loPhando lweGlasi lokuVeliswa kwamasele

Ukuveliswa kwamasele eglasi kuyaqhubeka ukuba yindawo esebenzayo yophando, kunye nezazinzulu zizama ukutyhila iinkcukacha ezithe kratya malunga nebhayoloji yabo yokuzala. Uphononongo olongezelelweyo luyafuneka ukuze kuqondwe imiba yemfuza neyendalo echaphazela ukhetho phakathi kokubeka iqanda kunye nokuzalwa okuphilayo kwii-amphibians. Ukongeza, ukuphanda iindlela ezisisiseko sokulungelelaniswa okukhethekileyo kwamasele eglasi ekubekeni iqanda le-arboreal kuya kunika ulwazi oluxabisekileyo malunga nokuvela kwezicwangciso zokuzala kwii-amphibians.
