Ixoxo lesihlahla elichofozayo (i-Acris crepitans blanchardi) lingele-oda lama-amphibiya angenamsila. Wathola igama elithile ngokuhlonipha i-herpetologist uFrank Nelson Blanchard.
Kuze kube muva nje, lolu hlobo lwama-amphibian lwaluthathwa njengama-subspecies ama-Acris crepitans, kepha ukuhlaziywa kwe-mitochondrial ne-DNA yenuzi kukhombisile ukuthi lolu uhlobo oluhlukile. Ngaphezu kwalokho, izici zokuziphatha nokufaka imibala kwexoxo lesihlahla elichofozayo kukwenza kube nokwenzeka ukukhetha lezi zinhlobo njengezimo ezihlukile zentela.
Izimpawu zangaphandle zexoxo lesihlahla elichofozayo.
Ixoxo lesihlahla elichofozayo yixoxo elincane (1.6-3.8 cm) elimbozwe ngesikhumba esimanzi. Imilenze yangemuva inamandla futhi inde maqondana nosayizi womzimba wonke. Ebusweni obushubile kunokwakheka okuyisikhumba esikhunjeni esiyimbudumbudu. Umbala we-dorsal uyahluka, kepha imvamisa iba mpunga noma nsundu. Iningi labantu linonxantathu omnyama, okhonjwe ngemuva, osekhanda phakathi kwamehlo.
Amaxoxo amaningi anomugqa omnyama onsundu, obomvu, noma oluhlaza. Umhlathi ongaphezulu unochungechunge lwezindawo eziqondile, ezimnyama. Abantu abaningi banomugqa ongalingani, omnyama ethangeni. I-Belly enemigqa eluhlaza okotshani noma onsundu.
Isikhwama sezwi siba mnyama, kwesinye isikhathi sithole umbala ophuzi phakathi nenkathi yokuzalanisa. Izinombolo zangemuva zinama-webbed amaningi, anebhlokhi elingathuthukisiwe kahle, anombala onsundu ngokumpunga noma amnyama, anombala oluhlaza noma ophuzi.
Amapayipi ekugcineni kweminwe yawo cishe awabonakali, ngakho-ke amaxoxo awakwazi ukunamathela phezulu, njengezinye izinhlobo zezilwane eziphila ezweni.
Onoshobishobi abanomzimba ohlangene namaphiko amancane we-caudal. Amehlo atholakala eceleni.
Umsila umnyama, ulula ekugcineni, onoshobishobi abakhula emifudlaneni enamanzi acwebile, njengomthetho, banomsila okhanyayo.
Ukusatshalaliswa kwexoxo lesihlahla elichofozayo.
Ukuthwebula amaxoxo ezihlahla kutholakala eCanada ngase-Ontario naseMexico. Lezi zinhlobo zama-amphibian zisatshalaliswa kabanzi enyakatho yoMfula i-Ohio naseningizimu ye-United States, entshonalanga yoMfula iMississippi. Abantu abaningi bahlala entshonalanga yeMississippi kanye nenani labantu eNyakatho Kentucky engxenyeni eseningizimu-mpumalanga. Ububanzi bexoxo elichofoza umuthi lifaka phakathi: i-Arkansas, iColorado, i-Illinois, i-Indiana, i-Iowa, iKansas, iKentucky, iLouisiana, iMichigan, iMississippi. Futhi neMissouri, Minnesota, Nebraska, New Mexico, Oklahoma, Ohio. Uhlala eSouth Dakota, Texas, Wisconsin.
Indawo esihlala kuyo ixoxo lomuthi elichofozayo.
Ixoxo lesihlahla elichofozayo litholakala nomaphi lapho kunamanzi futhi liyizinhlobo zezilwane eziphila emanzini nasemanzini eziningi kakhulu ebangeni lazo. Ihlala emachibini, imifudlana, imifula, noma yimaphi amanzi ahamba kancane, noma eminye imizimba yamanzi ehlala njalo. Ngokungafani namanye amaxoxo amancane amaningi, amaxoxo esihlahla aqunqwayo athanda imizimba yamanzi unomphela ngaphezu kwamachibi esikhashana noma amaxhaphozi. Ukuchofoza ixoxo lesihlahla kugwema izindawo ezinokhuni oluningi.
Izici zokuziphatha kwexoxo lesihlahla elichofozayo.
Ukuchofoza amaxoxo ezihlahla kungompetha beqiniso bama-Olympic amphibian jumping. Zisebenzisa izitho zazo zangemuva ezinamandla, zisuka phansi ngamandla bese zigxuma cishe amamitha amathathu. Imvamisa bahlala enqenqemeni lwamanzi odakeni olunodaka bese begxumela emanzini ngokushesha lapho impilo isongela. Ukuqunta amaxoxo emithi awawathandi amanzi ajulile, futhi esikhundleni sokuntywila njengamanye amaxoxo, babhukuda baye kwenye indawo ephephile osebeni.
Ukuzala amaxoxo esihlahla.
Ukuchofoza amaxoxo ezihlahla kuzala sekwedlule isikhathi, ngoJuni noma ngoJulayi, ngisho nakamuva, kepha izingcingo ezivela kwabesilisa ziyezwakala kusuka ngoFebhuwari kuya kuJulayi eTexas, kusukela ngasekupheleni kuka-Ephreli kuya maphakathi noJulayi eMissouri naseKansas, kusukela ngasekupheleni kukaMeyi kuya kuJulayi eWisconsin. "Ukucula" kwabesilisa kuzwakala njengensimbi "boom, boom, boom" futhi kufana nokushayisana ngamatshe amabili. Kuyathakazelisa ukuthi abesilisa baphendula ematsheni abantu abazalanayo ukuze bahehe amaxoxo. Amadoda amahlumela ezihlahla zemithi avame ukubiza emini.
Baqala "ukucula" kancane, bese bekhuphula ijubane labo ngendlela yokuthi akunakwenzeka ukuhlukanisa amasignali ezwi ngalinye.
Abesifazane benza amaqhugwana amaqanda amaningi, kuze kube ngamaqanda angama-200 ku-clutch ngayinye. Imvamisa zizalela emanzini angajulile, lapho amanzi afudumala kahle khona, ekujuleni kwamasentimitha angu-0.75. Amaqanda anamathisela ezimileni ezingaphansi kwamanzi ngeziqu ezincane. Intuthuko yenzeka emanzini emazingeni okushisa angaphezu kwamazinga angamashumi amabili nambili. Onoshobisho bacishe babe ngamasentimitha ubude ngemuva kokuvela, futhi bakhule babe amaxoxo abantu abadala kungakapheli amasonto ayi-7. Amaxoxo asemancane esihlahla esihlala njalo asebenza isikhathi eside futhi alala ngemuva kwamaxoxo abantu abadala.
Ukudla okunomsoco kwexoxo lesihlahla elichofozayo.
Ukuchofoza amaxoxo ezihlahla kudla izinambuzane ezincane ezahlukahlukene: omiyane, ama-midge, izimpukane, abangazibamba. Badla inani elikhulu kakhulu lokudla.
Izizathu ezingaba khona zokunyamalala kweselesele lokuchofoza.
Izinombolo ze-Acris crepitans blanchardi zehle kakhulu ezingxenyeni ezisenyakatho nasentshonalanga yebanga. Lokhu kwehla kwaqala ukutholwa ngawo-1970 futhi kuyaqhubeka kuze kube namuhla. Ukuchofoza amaxoxo ezihlahla, njengezinye izinhlobo zasemanzini, ukuhlangabezana nezinsongo ezinombolweni zazo kusuka ekushintsheni kwendawo nokulahleka. Kukhona nokwehlukaniswa kwezindawo zokuhlala, okukhonjiswa ekukhiqizweni kweselesele lomuthi ngokuchofoza.
Ukusetshenziswa kwezibulala-zinambuzane, umanyolo, ubuthi nokunye ukungcola
ukuguquka kwesimo sezulu, ukwanda kwemisebe ye-ultraviolet kanye nokwanda kokuzwela kwama-amphibian kumathonya e-anthropogenic kuholela ekwehleni kwenani lamaxoxo ezihlahla ezichofozwayo.
Isimo sokonga sexoxo lomuthi elichofozayo.
Ukuchofoza ixoxo lesihlahla akunaso isimo esikhethekile sokongiwa kwemvelo e-IUCN, njengoba sisatshalaliswa kakhulu empumalanga eseNyakatho Melika naseMexico. Lezi zinhlobo kungenzeka ukuthi ziyisibalo esikhulu sabantu futhi zisatshalaliswa ezindaweni ezahlukene. Ngalezi zindlela, ixoxo lomuthi elinqanyuliwe lingelezinhlobo zezinhlobo ezinenombolo zazo "ezingakhathazeki kakhulu." Isimo sokongiwa kwemvelo - isikhundla G5 (siphephile). Ezimweni zemvelo, lolu hlobo lwezilwane eziphila emanzini nasemanzini lilawula inani lezinambuzane.
