IiTeknikhi zokuzingela kunye neZakhono
Iibhere zePolar zizilo ezinobuchule obuphezulu kwaye ziphuhlise inani lezakhono zokuzingela kunye nobuchule obulungiselelwe ngokuthe ngqo kwindawo yazo ye-arctic. Owona mthombo wabo wokutya ngu uphawu, yaye ngenxa yoko, baye baphucula ubuchule babo bokuzingela emkhenkceni nasemanzini.
Obunye ubuchule bayo baziwa kakhulu ekuzingeleni kukuchwechwa, apho ibhere ichwechwa iye kutsho kumngxuma wokuphefumla kumkhenkce osetyenziswa zizinja zaselwandle ize ilinde ngomonde ixhoba layo ukuba linyukele umoya. Ngeli xesha, ibhere elimhlophe lihlasela ngokukhawuleza kwaye linamandla, libambe itywina ngaphambi kokuba libaleke. Obu buchule bufuna umonde kunye nobuchule obuninzi.
Elinye iqhinga lokuzingela kukuleqa emanzini. Ngaphandle kobukhulu bazo, iibhere ezimhlophe zindadi ezinamandla kakhulu kwaye zinokumangalisa ixhoba emanzini ngokuziqhubela phambili ngemilenze yazo enamandla. Ukongezelela, ukujoja kwabo kubenza bakwazi ukubona amatywina kumgama omde.
Izinto ezizixhoba eziphambili ekutyeni kwebhere emhlophe
Nangona zaziwa ngokuyintloko njengabatywini, ukutya kwebhere emhlophe ngokwenene kwahluka kakhulu. Apha ngezantsi ngamanye amaxhoba aphambili anokuthi enze ukutya kokumkani we-arctic:
- Amatywina aneendevu kunye namatywina aneRingi: Ezi zixhoba ezizithandayo kwiibhere ze-polar ngenxa yokuqukethwe kwamafutha amaninzi, okubabonelela ngamandla amaninzi.
- I-Narwhals kunye ne-belugas: Nangona zingengomthombo wokutya oxhaphakileyo, iibhere ezimhlophe zidla ngokuzihlasela ezi cetaceans xa zivaleleke emkhenkceni, zibanika omnye umthombo wezondlo.
- Iintlanzi: Nangona zingeyonxalenye ebalulekileyo yokutya kwazo, iibhere ezimhlophe zinokutya kwiintlanzi ezinjenge-polar cod kunye ne-arctic salmon xa zinikwe ithuba.
- Iintaka zolwandle kunye namaqanda: Ngexesha lokuzala, iibhere ezimhlophe zinokuhlasela amaqela eentaka zaselwandle ukuze zitye kuzo namaqanda azo.
Ukwahluka kwexesha lokutya kwebhere elimhlophe
Ukutya kwebhere elimhlophe nako kunokwahluka ngokuxhomekeke kwixesha lonyaka. Ebusika, xa umkhenkce wolwandle ukwincopho yawo, iibhere ziba namathuba angakumbi okuzingela iintini. Ngeli xesha, ukutya kwebhere emhlophe kusekelwe ikakhulu kumanqatha awafumana kwiintini.
Ehlotyeni, umkhenkce wolwandle uyanyibilika kuze kube nzima ukubambisa amatywina. Ngeli xesha lonyaka, iibhere ezimhlophe zinokunyanzelwa ukuba zongeze ukutya kwazo kunye nokunye ukutya okukhoyo, okufana neentaka zaselwandle, amaqanda, i-kelp, kunye ne-carrion ngamanye amaxesha. Kwakhona ngeli xesha iibhere zinokufumana amaxesha okuzila ukutya.
Ukufumana nokugcina amandla
Amafutha atyiwa ziibhere ezimhlophe kwixhoba lawo abanika amandla ashinyeneyo, agxininiswe ngendlela yeekhalori kunye nezondlo. La mandla abalulekile ukuzigcina kwimozulu ebanda kakhulu kwaye uzivumele ukuba zigcine amafutha amaninzi emzimbeni. Ngexesha lokufukama, iimazi ezikhulelweyo zixhomekeke ngokukodwa kula manqatha ukuze ziphile kwaye zondle amantshontsho awo.
Xa ibhere elimhlophe libamba itywina, lidla ngokutya kuphela uboya kunye ne-blubber layer, lishiya umzimba wonke lisiya kwezinye izilwanyana ezithatha amathuba njengeempungutye ze-arctic kunye nengabangaba. Amafutha agciniweyo abenza bakwazi ukunyamezela ixesha elide ngaphandle kokutya, kwaye ukuba bakwimeko entle emzimbeni, banokuphila iinyanga eziliqela bengatyi.
Impembelelo yokutshintsha kwemozulu kwisidlo sebhere elimhlophe
Ukutshintsha kwemozulu kuyingozi enkulu indawo yokuhlala kunye nokutya kwebhere elimhlophe. Ukunyuka kwamaqondo obushushu kubangela ukuba umkhenkce wolwandle unyibilike ngokukhawuleza kunesiqhelo, nto leyo eyenza kube nzima kakhulu kwiibhere ezimhlophe ukuba zizingele amatywina kunye nokunciphisa amathuba azo okutya.
Ngenxa yoko, iibhere ezininzi ezimhlophe zinengxaki yokungondleki nokulahlekelwa ngamafutha omzimba. Ukongeza, utshintsho lwemozulu luchaphazela inani labantu baselwandle, nto leyo inokukhokelela ekunciphiseni inani lamaxhoba akhoyo kwiibhere ezimhlophe. Kubalulekile ukuba kuthathwe amanyathelo ukunqanda ukutshintsha kwemozulu kunye nokukhusela indawo ehlala iibhere ezimhlophe kunye nemithombo yokutya.
