O le Arctic liu o loʻo aʻafia ai le taumafataga o urosa polar

Polo pea

O Polar bear, o le North Pole sili ona leaga manu feʻai, ua avea ma faʻailoga o suiga o le tau. I lenei itu o le lalolagi, o le vevela o loʻo tumau pea nai tikeri i lalo ole, faʻapitoa, mai -43 i le -26 tikeri Celsius tusa. O le mea lea, o nei matagofie matagofie manu na mafai ona tulimanu faʻamaufaʻailoga, o a latou meaai autu, e aunoa ma le tele naua faʻalavelave, ae faʻatasi ai ma le mafanafana o le lalolagi o lou tulaga ua suia tele.

E tusa ai ma se suʻesuʻega na lomia faasalalau i le »Journal of Animal Ecology», o loʻo faʻamalosia latou e 'aʻai fuamoa o pato, kusi ma gogosina ia ola.

O Charmain Hamilton, o se saienitisi i le Norwegian Polar Institute, na ia faamatala e faapea, a o lei amata ona aliali mai le vevela o le lalolagi i North Pole, na tumau pea le aisa o le laueleele i le talafatai i tafatafa o le glacier luma seia oʻo i le faaiuga o le taumafanafana. O le mea lea, o faʻamaufaʻailoga mafai ona malolo latalata i a latou mea manava ma urosa mafai ona tuli latou.

Peitaʻi, i Svalbard, o se atumotu o Nouei o loʻo tu i le Vasa Arctic, o le vevela ua faʻatoluina tulaʻi vave nai lo isi eria o le paneta Lalolagi, o lea la o le aisa e sili atu ona mataʻutia ma mataʻutia, aemaise lava mo polar pea.

Urosa matutua polar

»A o le solomuli o le sami aisa na faigata ai ia i latou ona sailia ni faʻamau faʻamau, ua faʻaalu nei e nai urosa ni taimi se tele i tafatafa o fulu o le sami, feoaʻi i nofoaga mamao atu i le aso ma faʻaalu le tele o taimi faʻataʻamilo solo i isi mea e maua ai meaʻai, pei o le faʻatupuina o kolone o pato ma kusiFai mai Hamilton.

90% o meaʻai a nei meaola e faasusu e faʻamoemoe i isi meaola. Ona o le suavai, ua atili ai ona tele latou faigata e maua a latou meaai masani. Afai e faʻapenei ona faʻaauauina, o le filifili meaʻai e mafai ona suia tele na mafai ai ona tineia latou, talu ai o le numera o manulele e laʻititi lava faʻatusatusa i le faitau aofai o polar bear.

E mafai ona e faitauina le suʻesuʻega iinei.
