Esinye sezinkathi eziqine kakhulu ezingeni lemvelo yisikhathi sasebusika. Lapho izilwane zithinteka kakhulu, kodwa-ke, eziningi zazo zivame ukuzivumelanisa nezimo ezithile ezimbi kakhulu, kulokhu okuthunyelwe uzokwazi konke mayelana izilwane ezilala ubuthongo nezici zayo, ungaphuthelwa!
Kuyini ukulala ubuthongo?
Izidalwa eziphilayo zinamakhono namakhono ahlukene azivumela, ezikhathini eziningi, ukuthi ziphile noma zizijwayeze endaweni ethile noma endaweni ethile. Kulo mbhalo sizokhuluma ngezilwane ezilala ebusika, kucatshangelwa amasu okuguquguquka ezikwazi ukuhlala nazo.
I-Hibernation imelela inqubo yokuguquka kwesimo sezulu, okwenzeka ngokuhamba komhlaba okukhiqiza uguquko olukhulu lwesimo sezulu, oluvame ukwaziwa ngokuthi inkathi.
Le nqubo ivame ukunqunywa izilwane, kucatshangelwa ukuthi ukubulawa kwayo kwenziwa ngenxa yezizathu zokongiwa kwezinhlobo ezehlukene ezihlala ezifundeni ezithile noma izindawo ezingaphansi kwezinguquko zezulu.
Ngakho-ke, ukulala kuchazwa njengenqubo eyenziwa ezinye izinhlobo zezilwane ukuze zivikeleke esimweni sezulu esibi kakhulu, futhi ziphinde zibe nenjongo yokulondoloza nokulondoloza impilo yazo isikhathi esithile.
Ukulala embhedeni kusho ukuvimbela izinguquko ezinkulu ezingeni lokushisa ezivame ukwenzeka ebusika. Imvamisa, izilwane ezilalayo zinokwakheka kwezinto eziphilayo eziyinkimbinkimbi kakhulu futhi zihluke ngokuphelele ku-morphology yezinye izinhlobo zezilwane, yingakho kuqashelwa ukuthi lezi yizinhlobo ezadalelwa ukumelana nalolu hlobo lwenselelo.
Lezi zilwane ngokuvamile zidlula enkathini ye-hypothermia elawulwa ngokuphelele. Ngenxa yalesi sizathu, izinga lokushisa layo ezingeni lomzimba ngokuvamile lihlala lizinzile.
Ngesikhathi sokulala, umzimba uba nesimo sokukhathala, lokhu kuvumela ukwehla kwamandla esilwane ukuthi kuthuthuke, okuvumela nokuncipha kokushaya kwenhliziyo kanye nokulawula ukuphefumula.
Lesi simo sokulala esenzeka ezilwaneni ezithile sihlaba umxhwele ngokuphelele, ngezinye izikhathi isimo sokudangala singokoqobo kangangokuthi ngezinye izikhathi kubonakala sengathi ukufa sekufikile esilwaneni.
Lokhu kungenxa yezibonakaliso ezikhiqizwa ngemva komphumela wokulala, kodwa kucatshangelwa ukuthi isikhumba sezilwane sibanda ngokuphelele, zonke izidingo ziyeka kancane kancane.
Kuleli qophelo, kuyinkimbinkimbi kakhulu ukubuka ukuphefumula ngenxa yalesi sizathu kukholelwa ukuthi isilwane sifile, kodwa ngokuqondile, akunjalo. Lapho inkathi yentwasahlobo efanele ifika, izilwane ziyakwazi ukuvuka, zilulame ngokushesha ngokujwayelekile okuphelele, zize zikwazi ukuzihlanganisa nempumelelo ephelele emisebenzini eziyenzayo nsuku zonke.
Izilwane zikulungiselela kanjani ukulala ebusika?
Lapho isikhathi sokulala senziwe, izilwane ziyakwazi ukuzilungiselela isikhathi eside ngaphambi kokufika kwenkathi eshiwo, ngakho-ke, zifuna ukuxazulula ukusetshenziswa kokudla kancane kancane ukuze ziphile kahle phakathi nale nqubo eshiwo ngenhla.
Le nqubo yokulungiselela ngokuvamile yenziwa okungenani amasonto ambalwa ngaphambi kokulala, yingakho izilwane eziningi zisebenzisa ithuba lokuzondla ngendlela engcono kakhulu, konke ezikwazi ukuzingela ukuze zidle kudliwa ngokuphelele.
Lo msebenzi wokuvimbela ubalulekile, ngoba ngokudla imisoco edingekayo, bayakwazi ukuthola ukwanda kwamafutha omzimba okudingeka umzimba wabo uhlale ubalulekile phakathi nenqubo abadlula kuyo.
Enye yezindlela lezi zilwane ezivame ukuyenza ukuguqulwa kwezinwele, ngoba ngazo, ziyakwazi ukuhlukanisa amakhaza, ukuze izinga lokushisa lomzimba wabo livikeleke ngokulingene, libe phakathi nenqubo, izilwane. bamukele isikhundla esibavumela ukuthi bazizwe bekhululekile endaweni bona ngokwabo abayilungiselele ukudlula kokulala.
Lesi sikhundla kufanele sikhululeke, ngoba kuso bazohlala isikhathi eside benganyakazi, kucatshangelwa ukuthi abanalo ikhono lokuhamba nganoma yiliphi ikhono, nokuthi ngaphezu kwalokho isikhathi sokulala singadlula izinyanga ezi-3.

Kulokhu, kufanele sicabangele ukuthi inqubo yokulala iphumelele ngokuphelele, izilwane ekuvimbeleni nasekulungiseleleni, zivame ukwenza umzamo wokuthola isitoreji esanele samafutha ngaphambi kokulala, lokhu ukuze uzizwe ulungele ukubhekana nomzuzu. ngokwedlulele.
Ekupheleni kwalolu hlelo, kuyabhekwa ukuthi kunzima ukuthi bavuke ebuthongweni, ngisho nalapho bethintwa. Kodwa-ke, kubalulekile ukusho ukuthi izinhlobo ezahlukene zezilwane zivame ukuvuka ngezikhathi ezithile, ngenhloso yokondla ngokunye ukudla ezikugcinele inqubo, lokhu kuyindaba yamagundane, aqoqa ukudla emigedeni yawo, futhi bese uzidla ngendlela efanele futhi ngaleyo ndlela uqinisekise ukusinda.
Yiziphi izilwane ezilalayo?
Ngokuvamile, izinhlobo ezilala ebusika yilezo zilwane ezinegazi elifudumele. Nokho, zikhona izilwane ezihuquzelayo ezenza lo msebenzi. Ucwaningo luye lwabonisa ukuthi ezinye izinhlobo zezimuncagazi, njengalezo ezinawo Izimpawu ze-nematodess abahlala ekujuleni komhlaba, nabo benza lo msebenzi.
Ukuthuthuka ngokufanele, uhlobo lokunciphisa ngokwezinga lokushisa lomzimba wabo, kanye nokukhiqiza amasu athile okuguquguquka aze aguqule nezinga labo le-metabolic. Phakathi kwezilwane ezenza ukulala ubuthongo, sithola okulandelayo:
- amaphengwini
- Ama-squirrels
- izimbila
- AmaHedgehogs
- ama-hamster
- Amakati
- Amabhere ePolar
Ngokuvamile, lapho ukhuluma ngokulala, izilwane zokuqala ezigqama ngesikhathi esifanele amabhere ase-polar. Kumele kuqashelwe ukuthi lezi zilwane azenzi inqubo yokulala kanjalo. Ingabe ufuna ukwazi akunjalo? Kunjalo. Sizochaza isizathu saleli qiniso eliyinqaba nelithakazelisayo.
Ucwaningo luye lwabonisa ukuthi umphumela wokulala akuwona umsebenzi owenziwa amabhere, lokhu kungenxa ye-morphology yamabhere evame ukuba yinkimbinkimbi ngandlela-thile. Ngakho-ke, isisindo sabo nosayizi wabo akubasizi ukuba bahlangabezane nezidingo ezifanele zokwenza le nqubo.
Lokhu kakade kudinga inani elikhulu lamandla elivumela izinga lokushisa layo ukuthi lizinze. Ngakho-ke, lokhu kubonisa ingozi enkulu kakhulu yebhere, engabangela ukufa kwalo ezimweni ezimbi kakhulu.
Umsebenzi owenziwa amabhere amhlophe empeleni unegama elibizwa ngokuthi ukulala kwasebusika, lokhu kunomehluko othile ohluke ngokuphelele esenzweni sokulala.
Ngokuyinhloko umehluko phakathi kokulala ebusika kanye nenqubo yokulala ukuthi izinga lokushisa lamabhere likhuphuka ngamadigri ambalwa phakathi nesikhathi esichitha ngaphakathi kwezakhiwo ezibizwa ngokuthi imigede. Nokho, akukho mehluko omkhulu phakathi kwenqubo eyodwa nenye, ngoba kuzo zombili izilwane zivame ukukhosela endaweni ethile.
Ngenxa yalesi sizathu, ezingeni lochwepheshe, zombili izakhi noma izinqubo zivame ukubizwa ngokuthi zifana nomunye nomunye, njengoba ukungalingani akukona okwedlulele. Nokho, kokubili akufani ngokuphelele kunalokho.
Ingabe akhona amanye amasu emvelo okujwayela amakhaza?
Kuze kube manje, inqubo yokulala iwukuphela kokuziphatha okwaziwayo ukuthi izilwane ezilungiselelwe kahle zenza ngokwemvelo nangokuqhubekayo. Nokho, kunezinye izindlela, ezingabizwa ngokufanelekile ngokuthi yi-hibernation.
Kukhona futhi ukuba khona kwezinye izinqubo ezenziwa ezinye izinambuzane zasemhlabeni ezifana nezikelemu, ezifika zenze uhlobo oluthile lokuphelelwa amandla, okuhlanganisa i- diapause, umphumela ozivumela ukuba zilungiselele ubunzima obuthile njengezikhathi zokushoda.
Ezinye izilwane ezinamagciwane, njengoba kushiwo ngenhla, zinenqubo yokuvimbela ehlobene nokukhula kwezibungu. Okwenziwa kusebenze ngokulandelana phakathi kwezinkathi zonyaka ezilandelanayo ezenzeka onyakeni. Ikakhulukazi ezindaweni ezibandayo ngokuphelele, ingakhula ngisho nasezimweni ezishisayo noma emazingeni okushisa futhi.
Ama-cetaceans anjengemikhomo, enza izinqubo zokufuduka, okubuye kubangele uhlobo lwenqubo lapho isilwane senza khona ukufuna ukudla okusebenzayo ukuze sisinde okungenani izinyanga eziyi-12.
Abanye Izilwane ezindizayo Futhi banamandla okwenza uhlobo oluthile lokulala, kucatshangelwa ukuthi banamandla okufuduka uma kwenzeka ukushintsha kungazelelwe kwesimo sezulu.
Ukubaluleka kokulala ezilwaneni
Ngokwemvelo engapheli esinayo, zonke izilwane zidlala indima ebalulekile, mayelana nezinqubo nokusekelwa kweplanethi. Ngakho-ke, zonke zibalwa njengeziyisisekelo, kungakhathaliseki ubukhulu bazo kanye nezinhlobo zazo.
Izilwane ezilala ebusika azihlukile, empeleni, lezi yizilwane ezinomshini wemvelo kanye ne-metabolism, ezifanele ukunconywa ngempela. Ukuba nokwenzeka kwezinhlobo ezenzelwe lolu hlobo lokusinda.
Ngakho-ke, ukubaluleka kwayo kulele nje ekubeni khona kwalezi. Namuhla, eziningi zalezi zilwane zisengozini yokusongelwa, ngenxa yezinguquko ezinkulu zomkhathi ezibangelwa ukufudumala kwembulunga yonke, ukuncibilika kwezigxobo, kanye nezinga eliphakeme lokungcoliswa kwemvelo.
Ngenxa yalokhu, izilwane ngezikhathi ezihlukahlukene zithintwa ngempela imiphumela iplanethi ebhekene nayo njengamanje. Ngenxa yalesi sizathu, ukusinda kuya kuba nzima kubo, hhayi nje ngenxa yezingozi abavame ukubhekana nazo, kodwa nangenxa yemiphumela emibi ehlukahlukene evela kwezinye izenzakalo ezincike kuphela kumuntu.
Ngenxa yalesi sizathu, abantu kufanele bakhuthaze ukunakekelwa kwezindawo zemvelo esinazo, ukunciphisa inani lemfucuza yezimboni, ngoba lokhu kungenye yezinto ezibhubhisayo eziwela emvelweni, okubangela inani elikhulu lemiphumela emibi kumama wethu. umhlaba. Ukuba izilwane, main abathintekayo ngezinga elikhulu.
Ekugcineni, sithemba ukuthi ufunde yonke imininingwane yokulala ezinhlobonhlobo zezinhlobo ezahlukene. Ngaphandle kokungabaza, isihloko esithakazelisayo ngempela esishiya okuningi ukucabanga mayelana nemvelo engavamile yalezi zilwane ezikwazi ukumelana nezimo ezinjalo.
