Variables: Vim li cas cov ntaub ntawv tsis raug ntau dua?

Qhov tseeb, suav polar bears tsis yooj yim li. Vim li cas? Ntawm ib sab, koj yuav tsum tsis txhob hnov ​​​​qab tias polar bears yog cov neeg yos hav zoov zoo nkauj uas yuav tawm tsam tib neeg. Kev ceev faj tshwj xeeb thiab qhov dav dav yog ib txwm xav tau. Qhov tseem ceeb tshaj plaws, polar bears tau zoo camouflaged thiab thaj chaw loj, feem ntau tsis meej pem thiab qee zaum nyuaj rau kev nkag. Polar bears feem ntau pom muaj nyob rau hauv qhov tsawg tsawg hauv cov chaw nyob deb, ua kev suav pej xeem hauv cov cheeb tsam no kim thiab tsis muaj txiaj ntsig. Ntxiv rau qhov no yog cov huab cua tsis tuaj yeem pom ntawm High Arctic.

Txawm hais tias tag nrho cov kev siv zog ntawm cov kws tshawb fawb, tus naj npawb ntawm polar bears tsis tuaj yeem txiav txim siab meej.

Science: Yuav ua li cas suav polar bears?

Cov lus piav qhia hauv qab no muab kev nkag siab me ntsis rau koj txog kev tshawb fawb txog kev ua haujlwm thaum lub sijhawm suav pej xeem polar bears hauv Svalbard hauv 2015 (J. Aars et al, 2019).

Lub ntsiab lus tsuas yog muab lub tswv yim ntawm txoj kev nyuaj npaum li cas kom tau txais cov kev kwv yees tau muab los saum toj no.

1. Tag nrho suav = Tus lej tiag

Hauv cov cheeb tsam uas yooj yim tswj tau, tag nrho cov tsiaj raug kaw los ntawm cov kws tshawb fawb los ntawm kev suav tiag. Qhov no yog ua tau, piv txwv li, nyob rau hauv me me Islands tuaj los yog nyob rau hauv tiaj tus, yooj yim pom cov chaw txhab nyiaj. Hauv xyoo 2015, cov kws tshawb fawb tus kheej suav 45 polar bears hauv Svalbard. 23 lwm cov bears qaum teb tau pom thiab tshaj tawm los ntawm lwm tus neeg hauv Svalbard thiab cov kws tshawb fawb tau ua pov thawj tias cov bears polar no tsis tau suav los ntawm lawv. Tsis tas li ntawd xwb, muaj 4 tus kab mob polar bears uas tsis muaj leej twg pom nyob, tab sis yog leej twg hnav lub dab tshos satellite. Qhov no qhia tau tias lawv nyob hauv thaj chaw kawm thaum lub sijhawm suav. Tag nrho ntawm 68 polar bears tau suav nrog txoj kev no nyob rau thaj tsam ntawm Svalbard Archipelago.

2. Kab Transects = Tus lej tiag + kwv yees

Cov kab yog teem rau ntawm qee qhov kev ncua deb thiab ya los ntawm qhov siab helicopter. Tag nrho cov polar bears pom raws txoj kev raug suav. Nws kuj tseem raug sau tseg tias lawv nyob deb npaum li cas los ntawm kab uas twb tau teev tseg lawm. Los ntawm cov ntaub ntawv no, cov kws tshawb fawb tuaj yeem kwv yees lossis xam seb muaj pes tsawg tus polar bears nyob hauv cheeb tsam.

Thaum lub sij hawm suav, 100 tus tib neeg polar bears, 14 leej niam nrog ib tug me nyuam thiab 11 leej niam nrog ob tug me nyuam tau pom. Qhov siab tshaj plaws ntsug nrug yog 2696 meters. Cov kws tshawb fawb paub tias bears nyob rau hauv av muaj feem ntau yuav raug kuaj pom dua bears nyob rau hauv pob dej khov thiab kho tus naj npawb raws li. Siv txoj kev no, 161 polar bears raug suav. Txawm li cas los xij, raws li lawv cov kev suav, cov kws tshawb fawb tau muab tag nrho cov kev kwv yees rau cov cheeb tsam uas tau them los ntawm kab transects li 674 (95% CI = 432 - 1053) polar bears.

3. Kev hloov pauv hloov = kwv yees raws li cov ntaub ntawv dhau los

Vim muaj huab cua tsis zoo, suav tsis tau hauv qee qhov chaw raws li tau npaj tseg. Ib qho laj thawj yog, piv txwv li, huab cua tuab. Vim li no, nws yuav tsum tau kwv yees tias muaj pes tsawg tus polar bears yuav raug tshawb pom yog tias suav tau tshwm sim. Nyob rau hauv cov ntaub ntawv no, satellite telemetry qhov chaw ntawm polar bears nruab nrog ib tug transmitter yog siv raws li ib tug pab kuj sib txawv. Ib qho piv txwv kwv yees tau siv los xam seb muaj pes tsawg tus polar bears yuav pom tau.

Nrhiav: Tag nrho cov suav hauv cov cheeb tsam txwv + suav & kwv yees hauv thaj chaw loj ntawm kab kev hloov pauv + kwv yees siv cov kev pab cuam hloov pauv rau thaj chaw uas nws tsis tuaj yeem suav = tag nrho cov naj npawb ntawm polar bears
