Namhlanje siza kuthetha ngeentlobo ze-amphibian ezibangele impikiswano enkulu kuba ibeka emngciphekweni ukusinda kwabanye abaninzi. Imalunga ne Inkunzi yesele. Ithathwa njengeentlobo ezihlaselayo ezibangela isoyikiso sokuphila kwezinye iintlobo ezipheleleyo esizifumana ezinye iindidi zamasele kunye nezilwanyana ezihlala emanzini. Oku kungenxa yokuba ayakhawuleza kakhulu kwaye amasele adlamkileyo kwaye anesakhono esikhulu sokuziqhelanisa.
Kweli nqaku siza kukuxelela zonke iimpawu, indawo yokuhlala, ukutya kunye nokuzala kwe-bullfrog.
Iimpawu eziphambili
Ludidi lweentlobo ezihlaselayo ezisuka kuMntla Melika kwaye ziqokelela zonke iintlobo ze-ecosystem ngokulula okukhulu. Nayiphi na i-niche ekhoyo emanzini ahlaziyekileyo kunokwenzeka ukuba i-bullfrog ikwazi ukuhlala ikoloni. I-bullsele lelosapho iRanidae kwaye livela kwilizwekazi laseMelika, ligxininisa ngokukhethekileyo kumazantsi eKhanada, eli lisuka eMexico nakulo lonke elaseUnited States. Ithathwa njengohlobo oluhlaselayo njengoko iseka ukhuphiswano olukhulu lwezilwanyana zalapha.
Kwaye kukuba ukubonakala kunye nokwandiswa kwe-bullfrog kungenxa yomntu. La masele athunyelwe kumazwe angaphandle ukuba abe zizilwanyana zasekhaya ezingaqhelekanga kwaye asetyenziswe njengokutya okumnandi. Ukusuka apha kubekho ukunqongophala kolawulo okubangele ukwanda kwelisele kuyo yonke indalo kunye nohlaselo lwalo. Ngokwangoku lelinye lawona masele andlongondlongo akhoyo kwaye aseke amathanga, abhengezwa njengenye yeentlobo ezili-100 eziyingozi nezitshabalalisayo ehlabathini.
Makhe sibone iimpawu zabo zomzimba. Imilenze yayo kunye nemilenze yangasemva mikhulu kakhulu, ifikelela kwi-25 centimeters ubude.. Dlulisa ubude ukuya kuwo wonke umzimba ngokwawo, olinganisa malunga ne-20 cm. Amasebe anobunzima obungaphezulu kwekhilogram kwaye alinganise phakathi kwe-17-46 yeesentimitha xa iyonke. Iphila iminyaka emalunga ne-10 logama ihleli endle, ngelixa iseluvalelweni inokufikelela kwiminyaka eli-16.
Intloko yesele njengoko ithe tyaba ngokupheleleyo kwaye ibanzi. Iveza ukugobeka eluswini kumacala omabini entloko. Iyaziwa ngenxa yokuba i-fold fold isemva kwamehlo kwaye ifikelela kwi-eardrum. Umbhobho wendlebe lilungu elibonisa i-dimorphism ngokwesondo. Enkosi kweli lungu siyakwazi ukuba isele yindoda okanye imazi na kuba iinkunzi azikho zikhulu kunemazi. Ukongeza, inomda omnyama.
Ibonisa amabala amaninzi amnyama kwaye isasazeka phezu kwe-torso, intloko kunye neziphetho. kwimilenze yangasemva baneminwe emi-4 enentambo phakathi kwayo yonke iminwe ngaphandle kowesine.
indawo yokuhlala yamasele
Nangona iludidi oluhlaselayo, eli sele linendawo yalo yendalo yokuhlala. Ziyezinye zezilwanyana ezinamandla amakhulu okuziqhelanisa neemeko ezahlukeneyo zokusingqongileyo. Yiyo loo nto sinokufumana i-bullfrog phantse kulo naluphi na uhlobo lwe-ecosystem enamanzi acocekileyo. Ingakumbi Inokukhula kakuhle kuloo manzi apho amaqondo obushushu angekho phantsi kakhulu.
Zikhetha amanzi amileyo amachibi, amadama, imigxobhozo okanye amachibi kunalawo emilambo kunye naloo mithombo yamanzi apho kukho imisinga. Ubukho bamanzi bubalulekile nanjengoko iyisilwanyana esihlala emhlabeni nasemanzini kwaye ifuna ukubamba ukutya kule nkqubo yendalo. La masele ngumthombo wokutya kwezinye izilwanyana ezihlala emanzini afana nookhwalimanzi, iintlanzi kunye neengwenya.
Nangona luhlobo oluvela kuMntla Melika, lukhona iindawo ezininzi ezahlukeneyo zejografi ezinemozulu eyahlukileyo kunye neemeko zendalo. Okwangoku sinokufumana i-bullfrog kwiindawo zaseYurophu, e-Asiya kunye naseMzantsi Melika kwaye kuzo zonke zithathwa njengezilwanyana eziyingozi kakhulu ezihlaselayo kwezo ndawo zifumaneka kuzo.
Ukutyisa amasele
Njengoko kulindelekile kwiintlobo ezihlaselayo, ukutya kwayo kukutya ngokupheleleyo. Yinyama edla inyama yasebusuku, oko kukuthi, ixesha lemini ezitya ngalo kusebusuku. Phakathi kwamaxhoba amaninzi kunye neentlobo ezahlukeneyo ezinokuthi zihlasele zilandelayo: ooqongqothwane okanye i-lepidoptera, ii-arachnids, iintshulube kunye neentshulube, iinkumba, intlanzi, amacilikishe, amacilikishe, amacilikishe, amacikilishe, amalulwane, iinyoka kunye neentaka..
Iyakwazi ukutya yonke into ewela emihlathini yayo kwaye ayihluthi. Esi sesona sizathu siphambili sokuba kuthathwe njengengozi kwiintlobo ezihlala kwezi ndawo. Ingozi yayo enkulu isungulwe kwezo ndawo zineentlobo ze-endmic ezingenakho ukuhlala ebusweni bokwandiswa kwe-bullfrog. Kwimeko ye tadpoles, ziqala ukutya i-algae kunye nezityalo zasemanzini. Xa zikhulile ziqalisa ukutya izilwanyana ezingenamqolo.
Ukuveliswa kwakhona
Makhe sibone ukuba yeyiphi indlela yokwandisa ezi zilwanyana ezihlala emanzini. Njengazo zonke izilwanyana eziphila emhlabeni nasemanzini, zichitha ixesha elininzi zingena naxa ziphuma emanzini. Kungexesha lokuzala ixesha apho kuya kuthi kuqhubekeke emanzini. Oku kubangelwa kukuba ngaphakathi emanzini zibeka amaqanda. LIinkunzi zizo ezithatha iimazi ze emva koko zihlangane. Imazi ijongene nokubeka amaqanda kwaye iyakwazi ukubeka amaqanda angaphezu kwama-20.000 ngexesha elinye. Esi sesinye isizathu sokuba inokwandiswa okukhulu. Nangona ingengawo onke amaqanda aphilayo, amaninzi kuwo ayasinda.
Uninzi lweetadpole aziyi kusinda njengoko zisebenza kakhulu kumarhamncwa kwaye akukho nzima kakhulu ukuzibona. La maqanda anencasa yokuba awakho mnandi kwincasa kwezinye iindidi zamacikilishe. Ngoko ke, kukho amaqanda ambalwa aphilayo. Kwiveki nje amaqanda ayaqanduselwa. I-tadpoles ikhula ngokuqhubekayo de ikhule kwaye iphile phantsi kweengozi ezifihlakeleyo ezifana namarhamncwa.
Njengoko ubona, luhlobo oluyingozi kakhulu lwesele elikwaziyo ukususa izilwanyana zasekhaya. Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga ne-bullfrog kunye neempawu zayo.
