Ufudu lokuxuba (i-Emydoidea blandingii) lungolokuhlelwa kofudu, isigaba sezilwane ezihuquzelayo.
Ufudu lokuxuba lusakazeka.
Izimfudu zikaBlending zidabuka eNyakatho Melika. Ububanzi budlulela ngasentshonalanga kuya e-Southeast Ontario naseningizimu yeNova Scotia. Zitholakala eningizimu ye-United States esifundeni samachibi amakhulu. Izilwane ezihuquzelayo zisakazeka enyakatho-mpumalanga yeMaine, enyakatho-ntshonalanga yeNingizimu Dakota naseNebraska, kufaka phakathi eningizimu-mpumalanga yeNew York, ePennsylvania, e-Illinois, e-Indiana, e-Iowa, eMassachusetts, eMichigan, eSoutheast Minnesota, eNew Hampshire kanye nezwe lase-Ohio. Atholakala eWisconsin, eMissouri.
Indawo yokuhlala ufudu.
Izimfudu ezixubayo yizilwane ezinamanzi amancane, zihlala ikakhulukazi ezindaweni ezingamaxhaphozi ezingajulile, lapho kunezimila eziningi zasemanzini. Lezi zilwane ezihuquzelayo zihlala emaxhaphozini esikhashana lapho zicasha khona ezilwaneni ezidla ezinye. Ziphinde zondle emadlelweni angenasawoti, ikakhulukazi ngesikhathi sasehlobo. Ngesikhathi sasebusika, lezi zimfudu zamanzi ahlanzekile zitholakala kakhulu ezindaweni ezinamanzi angaphansi kwemitha elilodwa ukujula, njengamaxhaphozi, amachibi omiswe nemifudlana.
Lezi zindawo ezingamaxhaphozi zingama-35 to 105 cm kuphela ukujula.
Abesifazane bakhetha izindawo zomhlaba zokwakha izidleke lapho kungekho zimila emhlabathini. Ukushoda kwezimila akuhehi abantu abangaba yizilwane ezivela endaweni ezungezile. Izimfudu zakha izidleke zazo ezinhlangothini zemigwaqo nasemaphethelweni endlela. Okondla nokukhwelana, izimfudu zikaBlending zihambela ezindaweni ezingamaxhaphozi zesikhashana kanye nasezixhaphozini. Izindawo ezihlala emhlabeni ziyindawo ekhethwayo yokudla ebusuku.
Izimfudu ezincane zibhekwa ikakhulukazi emizimbeni yamanzi engajulile eseduze nebhande lehlathi. Lokhu kukhethwa kwendawo yokuhlala kunciphisa ukuhlangana nezilwane ezidla ezinye.
Izimpawu zangaphandle zofudu oluhlanganayo.
Igobolondo elibushelelezi lofudu oluhlanganayo lunsundu onsundu noma limnyama ngebala. Ngemuva kunezindawo eziphuzi namaphethini ahlukahlukene amnyama nephuzi ahambisana nezimbungulu. Igobolondo lofudu olukhulu lungalinganisa kusuka kumamilimitha ayi-150 kuye kwangama-240. Isisindo sisuka ku-750 kuye ku-1400 amagremu. Ikhanda liyisicaba, umhlane nezinhlangothi kuluhlaza okwesibhakabhaka-mpunga. Amehlo aphumele ngaphandle kumlomo. Izikali eziphuzi zimboza izitho nomsila. Kukhona ukugoba phakathi kwezinzwani.
Yize kungekho mehluko ophawulekayo ngosayizi phakathi kwabesifazane nabesilisa, abesilisa baneplastron ye-concave ethe xaxa.
Amaluphu asohlangothini lwegobolondo lomgogodla ahamba phakathi neminyaka emibili ezimfudu ezincane, futhi angavaleka ngokuphelele lapho izimfudu zifinyelela eminyakeni emihlanu. I-plastron yezimfudu ezincane imnyama ngombala ophuzi onqenqemeni. Imisila mincane kunaleyo yabantu abadala. Izimfudu zidwetshwe ngemibala ekhanyayo, zinamagobolondo ayindilinga amaningi, osayizi bazo bahluka kusuka kumamilimitha angama-29 kuye kwangama-39, nesisindo sisuka ku-6 kuye ku-10 amagremu. Izimfudu ezindala zingabhalwa ngamasongo egobolondo azo.
Ukuza ufudu Ukuxuba.
Izimfudu ezixubayo zizala ikakhulukazi ekuqaleni kwentwasahlobo, ngoMashi nasekuqaleni kuka-Ephreli, lapho kuphela ubusika.
Abesifazane bakhiqiza izingane ezineminyaka ephakathi kuka-14 no-21, kanti abesilisa bayakwazi ukuzala cishe eminyakeni eyi-12 ubudala.
Zikhwelana nabesilisa abaningana. Kodwa-ke, ngesikhathi sokuqomisana, abesilisa banolaka kakhulu futhi baluma abesifazane egobolondweni. Insikazi kwesinye isikhathi iyabhukuda isuke eyeduna, bese eyeduna imjaha emanzini bese inikina ikhanda layo phezulu naphansi, ikhulule amagwebu omoya ngaphansi kwamanzi. Abesifazane babeka amaqanda kanye ngonyaka ngasekupheleni kukaJuni nasekuqaleni kukaJulayi. Zakha izidleke ebusuku izinsuku ezingaba yishumi. Bakhetha izindawo eziphephile ezinezimila ezingatheni emhlabathini. AmaLake shores, amabhange amatshe amatshe amancanyana, amabhishi kanye nemigwaqo kuyindawo evamile yokwakha izidleke. Amaqanda oFudu abekwa emigodini eyebiwe ukujula ngamasentimitha ayi-12. Ubukhulu be-Clutch buhluka kusuka kumaqanda ama-3 kuye kwayi-19. Amazinga okushisa ayafukama avela ku-26.5 degrees kuya kuma-30 degrees. Izimfudu ezincane zivela ngemuva kwezinsuku ezingama-80 kuya kwezingu-128, imvamisa ngoSepthemba nango-Okthoba. Zinesisindo esingu-6 kuya ku-10 amagremu. Izimfudu ezisencane ziyahamba zifuna izindawo zokuhlala zasemanzini ezifanelekile zasebusika. Ngokucatshangelwa, izimfudu ezihlanganayo zihlala emvelweni iminyaka engama-70-77.
Ukuziphatha kofudu lokuhlanganisa.
Yize izimfudu zikaBlending zihlotshaniswa nendawo ehlala emanzini, zivame ukuphuma emanzini ukugcwala izingodo, imibhede edungekile noma enye indawo. Lezi zimfudu zihamba zifuna izindawo ezinokudla okuningi. Eziduna zimboza cishe i-10 km, abesifazane kuphela i-2 km, futhi kuphela ngesikhathi sokufukamela lapho zingakwazi ukuhamba ibanga elifinyelela ku-7.5 km. Abantu abadala bavame ukubuthana endaweni eyodwa, lapho kunezinhlokomo ezisukela kuma-20 kuye kwezingama-57 ehektheleni ngalinye. Ngo-Okthoba nangoNovemba, bakha amaqembu ebusika, ahlala ikakhulukazi emachibini, acashe kuze kube sekupheleni kukaMashi.
Ukuhlanganisa ufudu ukudla.
Izimfudu ezihlanganayo ziyizilwane ezinwabuzelayo ezi-omnivorous, kepha uhhafu wokudla kwazo uqukethe ama-crustaceans. Zidla zombili inyamazane ephilayo kanye nesidumbu. Badla izinambuzane nezinye izinambuzane ezingenamgogodla, izibungu ze-dragonfly, amabhungane, kanye nezinhlanzi, amaqanda, amaxoxo, neminenke. Ezitshalweni bakhetha uphondo, idadaweed, isedge, umhlanga, futhi badle nembewu. Izimfudu ezindala zidla ukudla kwezilwane, kuyilapho ama-juveniles ikakhulukazi edla utshani.
Isimo sokongiwa kofudu oluhlanganayo.
Ngokwe-IUCN Red List, izimfudu zikaBlending zisengozini, isimo sazo sicishe sibe sengozini. Lezi zimfudu zikuSithasiselo II seCITES, okusho ukuthi uma ukuhweba ngalezi zinhlobo zezilwane ezihuquzelayo kungalawulwa, izimfudu zizobeka engcupheni.
Izinsongo ezinkulu ezinhlotsheni: ukufa emigwaqeni, izenzo zabazingeli abangekho emthethweni, ukuhlaselwa yizilwane ezidla ezinye.
Kuthathwa izinyathelo zokunqanda ukusetshenziswa kwemithi yokubulala ukhula ezindaweni zokuhlala ezingamaxhaphozi ezaziwayo zezimfudu zaseBlanding. Izindlela zokongiwa kwemvelo zikhona kulezi zindawo zesikhashana, futhi imigwaqo nezakhiwo zivunyelwe kuphela kude kude nezindawo ezingamaxhaphozi.
Izimfudu zokuxuba zihlala ezindaweni eziningi ezivikelwe kulo lonke uhla, kufaka phakathi inani elikhulu kakhulu labantu elaziwa eNebraska. Izinhlelo zokongiwa kwemvelo zenziwe emazweni amaningi ase-US naseNova Scotia.
Izindlela zokongiwa kwemvelo zifaka:
- ukunciphisa ukufa kwezimfudu emigwaqweni (ukwakhiwa kocingo ezindaweni lapho ezihuquzelayo zihamba emigwaqweni),
- ukuvinjelwa okuphelele kokudoba okuthengiswayo,
- ukuvikela amaxhaphozi amakhulu namanzi amancane esikhashana. Kanye nokuvikelwa okudingekayo kwezindawo ezisondelene nomhlaba ezisetshenziselwa ukwakha izidleke futhi njengemigudu yokuhamba phakathi kwamaxhaphozi
- ukususwa kwezilwane ezindaweni lapho kuzalela khona izimfudu.
