Ngaphezu komkhawulo othile wokushisa, izinto eziphilayo zikuthola kunzima ukusebenza. Ochwepheshe bakwaWWF (World Wide Fund for Nature) bayakuxwayisa lokhu, futhi nabo bangafa. Ukushisa okuphezulu okuthinta abantu kakhulu, kuthinta nezilwane. Ngokuya ngohlobo nokuthi luhlobo luni, izinguquko ziqala ukuqashelwa. Singathola yonke into kusukela ekuncipheni kokukhiqizwa kwemfuyo kuya ekuncipheni kwenani labantu ezinhlobonhlobo ezibucayi kakhulu. Ukuze uthole ulwazi olwengeziwe mayelana nokukhiqizwa kwemfuyo, sicela uthintane ukuthi ukushisa kuzithinta kanjani izilwane.
Kubuye kuthinte nezimbali, ukushisa okweqile, futhi okuhambisana nemvula encane, kubangela isibonelo ukuthi izimbali zome. Izinyosi azikwazi ukukhiqiza umpe omningi. Ngezikhathi ezinjengalezi, lo mkhiqizo uyehla. Ngesikhathi samahora okuqala osuku, bangazinikezela ekuqoqeni umpe. Ngemuva kwalokho, kufanele basishiye, bapholise isidleke ngamanzi bese basigcina phakathi kuka-32-35ºC.
Izithinta kanjani izinyoni?
Igagasi lokushisa ngenkathi lapho kukhona khona okuzalayo, kubangela ukuthi izinhlobo ezikhulisa amaphuphu azo zikuthole kunzima ukuthola amanzi. Ngabaphuzi abambalwa ababikezelayo, kubangela ukwanda kwamandla okufuna amanzi amaningi futhi uyihambise kalula. Lokho kunomthelela oqondile enanini lezinkukhu ezisindayo.
Kuyaqapheleka futhi ukuthi izinyoni ezihambisana nezindawo ezinotshani ziyancipha zibe luhlaza ngokunyuka kwamazinga okushisa. Ukukhiqizwa kwezinyoni kuyawa, kanye nezinyoni ezidla izinambuzane. Lezi zamuva zihlotshaniswa nenani lezimbali ezikhona. Kulo mongo, kubalulekile ukuqonda umthelela wamagagasi okushisa ezilwaneni zasendle, ikakhulukazi uma kubhekwa lokho amagagasi okushisa ziyisici esiyinhloko. Ngaphezu kwalokho, ukuguquka kwesimo sezulu kudala ukwanda kwamazinga okushisa nakho okunomthelela kulezi zinqubo zokuzala. Ukuze uqonde ukuthi ukushisa kuzithinta kanjani izilwane zasendle, kuphakanyiswa ukuthi kubuyekezwe isexwayiso sokushisa okwedlulele.
Bazivikela kanjani?
Ngakolunye uhlangothi izinyoni Basebenzisa izimpaphe zabo njenge-air conditioner. Kuyindlela ejwayelekile kakhulu ezinhlotsheni eziningi. Isibonelo, abantu basebenzisa izinwele zethu njengeziqandisi kancane ehlobo, ukuze izinga lokushisa lingabi phezulu kakhulu. Ngokulinganayo nangokuzibonela iyasivikela emakhazeni ebusika.
Izinyoni zasemadolobheni zinethuba elingcono lokusinda ezindaweni zasemadolobheni. Ngokuvamile kunezindawo ezinokudla namanzi njalo, njengalezo ezisetshenziselwa ukuchelela. Lokhu kwenza kube lula ukuthi bachume. Indlela enhle yokusiza ukunciphisa umphumela wokushisa ezinyonini ukubeka imisele yamanzi noma amabhodwe amanzi. Ukuze uqonde kangcono ukuthi bazivikela kanjani kulezi zimo ezimbi kakhulu, kuphakanyiswa ukuthi kubuyekezwe ubudlelwano phakathi kwezilwane nokushintsha kwesimo sezulu.
Ngokuvamile, izilwane zisabela ekushiseni ngendlela efanayo kubantu. Banciphisa izinga lomsebenzi wabo, bafune isiphephelo emthunzini, futhi amazinga okushisa aphezulu abangela izinkinga ze-metabolic. Kukhona abanye ngaphezu kwalokho, njengokuthi izinja, ezizwela kakhulu ekushiseni kunokuba sicabanga. Njengoba zingakwazi ukujuluka ukuze zizipholise, sizibona zilele phansi zifuna umoya opholile, kuyilapho zihefuzela. Ukuze uthole ukuhlaziya okujulile, bheka ukushisa kwamagagasi ezilwaneni.
Izithinta kanjani izilwane ezihuquzelayo?
Kuzo sithola ukuthi, kusuka cishe ku-32ºC centigrade Kuyabathinta ocansini uma bezala. Lokho kusho ukuthi, kuzalwa abesifazane abaningi. Ibhalansi evame ukuba khona phakathi kwabo bobabili ubulili iyashintsha. Lesi sici sibalulekile uma kucatshangelwa ukuthi isimo sezulu sishintsha kanjani ukuguquguquka kwenani lezilwane ezihuquzelayo.
Ziyizilwane ze-ectothermic, azikwazi ukukhiqiza ukushisa kwazo. Njengoba nje emazingeni okushisa aphansi, ukusabela kwawo kwe-metabolic kuyehla futhi nezinga lomsebenzi wabo liyancipha, azwela emazingeni okushisa aphezulu. Esimweni esinjalo, ukusabela kwamakhemikhali kwaphuma ebhalansi futhi umsebenzi wamaprotheni ahilelekile kuwo, ama-enzyme, uyashintshwa noma angancishiswa. Ukuze uqonde kangcono lesi simo, kunconywa ukufunda kumphumela wesiqhingi sokushisa.
Izithinta kanjani izinhlanzi?
Lapho izinga lokushisa kwamanzi likhuphuka, bavame ukuthuthela kwezinye izindawo.. Izinyoni zasolwandle, esingakaze sisho ngaphambili, ngokwesibonelo yibo abalimele lapha. Ukuze bafune ukudla, ngokuvamile kudingeka bahambe amabanga amade. Futhi kuthinta nokugqokwa kwabo komzimba kanye nokudabuka ezinganeni zabo.
Endabeni yezinhlanzi, yizilwane ezivame ukuhlala emazingeni okushisa azinzile kakhulu. Emvelweni womoya izinga lokushisa liyahlukahluka kakhulu, kepha endaweni yasemanzini ukwehluka kuzinze kakhudlwana. Ngakho-ke, uhlobo ngalunye "lunendawo yalo." Sinezinhlanzi ezithile ezingaphila emanzini aneqhwa esigxotsheni, kanti ezinye emanzini ashisayo kakhulu. Kepha ukwehluka kwamazinga okushisa emanzini alo kuzothinta ngqo inani labantu. Uma bengathola indawo yokukhosela kwenye indawo bazokwenza njalo; Ngokuphambene nalokho, noma yikuphi ukuphakama noma ukwehla kwezinga lokushisa kubangela ukuthi inani labantu bakhona lehle lisuka ezingeni elifanele lokushisa.
