Txawm hais tias Bd, tau piav qhia tias yog kab mob phem tshaj plaws uas tau sau tseg, tau rhuav tshem ntau pua hom amphibian thoob plaws ntiaj teb thiab ua rau ntau pua tus neeg poob qis dua, cov tsiaj nyob hauv Africa tau xav tias yuav tau dim ntawm kev kub ntxhov.
Ntawm qhov tsis sib xws, kev tshawb fawb luam tawm hnub Wednesday hauv Cov Hauv Ntej Hauv Kev Tshawb Fawb Txog Kev Tiv Thaiv qhia tias Bd tau ruaj khov nyob thoob plaws tebchaws Africa thiab tsuas yog mus tsis tau pom dua.
Txawm hais tias muaj kab mob sib kis ntawm Bd tuaj yeem tshawb pom los ntawm xyoo 1930s thaum ntxov, cov kab mob fungal tiag tiag pib kis thoob plaws tebchaws hauv xyoo 2000 thiab nyob ib ncig ntawm kaum xyoo tom qab ntau dua 20% ntawm cov qauv kuaj pom tus kab mob zoo, nce siab txog 74% hauv qee qhov. cheeb tsam.
Cov kws tshawb fawb tau hais tias qhov kev tshawb pom - uas yog sib xws nrog qee cov lus ceeb toom ntawm amphibian tuag-offs thiab extinctions - qhia tias cov fungus tau raug saib xyuas, es tsis tuaj, thiab taw tes rau qhov kev hem thawj loj rau Africa ntau hom amphibian, nrog rau cov nyob hauv nruab nrab, sab hnub tuaj. thiab thaj tsam sab hnub poob ntawm Africa muaj kev pheej hmoo loj tshaj plaws.
Nyob rau hauv cov cheeb tsam uas cov fungus tau raug soj ntsuam ntau dua, Bd tau tsav ntau pua hom amphibian mus rau kev ploj tuag lossis ze-extinction thiab ua rau cov pejxeem poob ntau dua 500 hom, ua rau nws yog cov kab mob phem tshaj plaws hauv keeb kwm ntawm biodiversity.
Dab Tsi Los Saib
Amphibians tseem ceeb ntau dua li cov neeg feem coob paub thiab poob lawv tuaj yeem muaj qhov tshwm sim loj. Qhov tseem ceeb tshaj plaws, amphibians yog hom pob zeb tseem ceeb hauv ntau lub ecosystems, txhais tau tias lawv qhov kev poob tuaj yeem hloov pauv ib puag ncig rau qhov tsis zoo. Cov kev cuam tshuam hauv qab no tuaj yeem muaj kev cuam tshuam loj, xws li tsav tsheb malaria mob hnyav vim tias muaj cov qav tsawg dua kom yoov tshaj cum. Biodiversity kuj yog ib qho tseem ceeb ntawm kev tsim kho tshiab, tshwj xeeb tshaj yog cov tshuaj, thiab ntau hom tsiaj uas ploj lawm qhov tsawg dua peb yuav tsum tau kawm los ntawm lawv. Piv txwv li, salamanders - uas muaj lub peev xwm zoo tshaj plaws los kho cov ntaub so ntswg, cov plab hnyuv siab raum lossis txawm tias ceg ceg - tab tom kawm nrog rau kev qhib txoj hauv kev tshiab ntawm kev kho qhov txhab loj.
Dab Tsi Peb Tsis Paub
Nws tsis paub meej tias vim li cas Bd tsuas yog pib tawm hauv tebchaws Africa los ntawm 2000, ntau tom qab ntau dua li lwm lub tebchaws thiab ntau xyoo tom qab lwm qhov hauv ntiaj teb tau tshaj tawm tias muaj kev sib kis loj Bd. Nws tuaj yeem yog lub sijhawm, hais tias tus kws tshawb fawb Vance Vredenburg, tus xibfwb ntawm San Francisco State University thiab University of California Tsev khaws puav pheej ntawm Vertebrate Zoology, Berkeley. Kev nce huab cua mus ncig ntawm tib neeg thiab cov khoom thauj, uas tuaj yeem pab thauj thiab kis tus kab mob, "tseem yog tus neeg ua txhaum," Vredenburg tau hais. Kev hloov pauv huab cua kuj tseem tuaj yeem ua lub luag haujlwm, Vredenburg tau hais tias, tej zaum los ntawm kev ua kom cov neeg amphibians muaj kev cuam tshuam ntau dua los yog ua rau thaj chaw muaj chaw tos txais cov kab mob.
Kev Nkag Siab Hais
Kev nce nrawm ntawm Bd hauv 2000 tuaj yeem qhia tau tias cov kab mob twb tau tsav cov neeg nyob hauv tebchaws Africa, Vredenburg tau hais. Vredenburg hais ntxiv tias "Kev tuag ntawm amphibians twb tau tshwm sim hauv Africa yam tsis muaj leej twg paub txog nws," Txawm hais tias kev tshem tawm cov kab mob yuav ua tsis tau, Vredenburg tau hais tias kev paub ntau ntxiv txog yuav ua li cas thiab thaum twg nws kis tau tuaj yeem cawm cov kab mob amphibian. Muab hais tias nws "zoo li tau txav mus thoob ntiaj teb los ntawm tib neeg, peb muaj kev coj ncaj ncees los koom nrog thiab sim tswj thiab txo qis thaum twg los tau," Vredenburg tau hais.
