Izilwane ezimhlophe ezimhlophe zingafela ngenxa yokushintsha kwesimo sezulu, ucwaningo luphakamisa

Izilwane ezimhlophe ezihlukunyeziwe zisengozini yokufa ngoba ukuguquka kwesimo sezulu kubangela ukuwa kwesembozo seqhwa, kubashiye badalulwe futhi basengozini, kubonakale ucwaningo olusha.

Ososayensi basePoland bebelokhu belandela icala elikhathazayo le-Weasel e-White-Camera, eliveza isembozo salo se-tawny ebusika ijazi elibi elivumela ukuba lihlangane kahle endaweni yalo emnandi.

Kepha abaphenyi bathole ukuthi phakathi kuka-1997 no-2007 inani lezinsuku ezinekhava yeqhwa laphakade e-Białowieża Forest, ePoland, enqunyuliwe, ukusuka ku-80 kuya ku-40.

Kusho ukuthi izidalwa ezincane zibanjwa endaweni engafaneleke ngokuphelele, lapho zilula izisulu zezilwane ezidla njengezimpungushe nezimpungushe.

Iqembu elisePoland Academy of Sciences lithole ukuthi ngezinsuku lapho kunesembozo esincane sasebusika sasebusika, inani lama-Weasels amhlophe asebusika akwazile ukuwathatha amaphesenti angama-20 aphansi, aphakamisa abanye ababebulewe.

Phambilini bebengabusa, ngoba amajazi abo ngabe awanikeze inzuzo yokusinda.

Inkinga kungenzeka ukuthi iphatheze ezinye izilwane ezincelisayo ezimhlophe ezihlangene nezinyoni ezihlala ezindaweni ezisengozini yokushintsha kwesimo sezulu njenge-Fox ye-Arctic njengoba ikhava yeqhwa iqhubeka nokuya emhlabathini wama-greens nama-brown.

Ososayensi baqophe izinhlobo ezingama-21 zezilwane ezincelisayo nezinyoni eziphenduka zaba mhlophe ebusika ukucashe ezindaweni ezinamaqhwa kubandakanya ne-hare hare, i-hamster yaseSiberia, i-charkrabbit enomsila omhlophe kanye ne-willow ptarmigan bird kanye ne-willow ptarmigan inyoni.

Umlobi uDkt Karol Zub, utshele iThelegraph: [Ngokuqinisekile imithetho efanayo isebenza kuzo zonke izilwane ezincelisayo ezincelisayo nezinyoni.

. Lokhu kubonakala kungabi ngumphumela omkhulu, kepha umphumela wokuqongelela ubusika ungaba nomthelela omkhulu ekufeni kwezinhlobo zezinhlobo.

[Kungenzeka kakhulu ukuthi ema-Weasels amhlophe asekusasa aseduze nasezitofu zizonyamalala ngokuphelele ezindaweni eziningi zaseNyakatho Yurophu naseNyakatho Melika.

"Zizothathelwa indawo ama-morphs ansundu noma zizovela futhi zizovela ngokuhamba kwesikhathi ngenkathi, zimhlophe ngokwengxenye yesikhathi esifushane."

Abaphenyi baphinde basebenza izivivinyo besebenzisa amathoyizi ama-Weasels ansundu namhlophe ukubona ukuthi imibala empeleni yenza umehluko kubazingeli.

Lapho sebemisa izicupho zekhamera bathola inqwaba yezilwane, njengezimpungushe, izimpungushe nezinyoni ezidla inyama zisondele kumathoyizi amhlophe, kepha akekho owayekhombise intshisekelo ezinhlotsheni ezinsundu.

Ababhali bathi lokhu okutholakele kubonisa ukuthi ukwehla okumanzi okumhlophe okucashile kungenxa yokwanda kokutholwa kokutholwa kwabahlaseli endaweni encane yeqhwa.

Abaphenyi bathembela ukuthi izilwane zizofunda ukuzivumelanisa nezimo, kepha zithi azikwazi ukunquma izilwane ziyanyamalala ngokuphelele.

I-Weasels engaguquki ngombala ebusika, maningi amathuba okuthi iphile ukuze idlule ezinhlobonhlobo zabo ezinsundu, ukukhulisa izinombolo zezinhlobo ezimnyama.

UDkt Zub ungezwe: [Akufanele sibukele phansi amandla okukhethwa kwemvelo. Siyethemba ukuthi kanye nokufudumala kwesimo sezulu esikhathini esizayo, amazinga okushisa asekwindla nawo azokwanda, ahlinzeke isibonakaliso esengeziwe kuma-weasels ukuba ambezele i-moult yawo.

Ucwaningo lushicilelwe emibikweni yesayensi yesayensi.

Ngaphezu kwalokho, uma unentshisekelo ephepheni lesikebhe lesikebhe e- EVA noma i - EVA SUP Pad & Eva Traction Pad , sicela ukhululeke ukuxhumana nathi.
