Do omenjenega mednarodno odmevnega preboja slovenskih znanstvenikov je pri\u0161lo na podro\u010dju visokotehnolo\u0161ke “forenzi\u010dne” tehnike, ki se ga sicer pri\u010dakuje le v najve\u010djih molekularnih laboratorijih z ve\u010dmilijonskim prora\u010dunom.<\/p>\n

“Nam pa je to uspelo v majhnem Jamskem laboratoriju Tular, brez javne finan\u010dne podpore, s prostovoljskim delom in navdu\u0161enjem sodelujo\u010dih raziskovalcev in partnerjev,” poudarja vodja raziskave Gregor Aljan\u010di\u010d.<\/p>\n

\u010clanek z naslovom Okoljska DNK v jamski biologiji: pove\u010danje raz\u0161irjenosti in taksonomske posledice za \u010dlove\u0161ko ribico je bil objavljen 27. marca, dostopen pa je na spletnem naslovu http:\/\/www.nature.com\/articles\/srep45054<\/a>.<\/p>\n

Kot pojasnjujejo avtorji raziskave, je iskanje raz\u0161irjenosti \u010dlove\u0161ke ribice zaradi nedostopnosti kra\u0161kega podzemlja potekalo zelo po\u010dasi, \u0161tevilna najdi\u0161\u010da se pozna le po pri\u010devanju izpred 150 ali ve\u010d let.<\/p>\n

\u010clanek tako utemeljuje inovativno molekularno orodje za raziskovanje raz\u0161irjenosti \u010dlove\u0161ke ribice v nedostopnem kra\u0161kem podzemlju. S pomo\u010djo detekcije njene okoljske DNK (eDNA) lahko \u010dlove\u0161ko ribico “forenzi\u010dno” zaznajo v podzemeljski vodi, ne da bi jim jo bilo treba videti.<\/p>\n

Posebno pozornost so posvetili \u010drni \u010dlove\u0161ki ribici iz Bele krajine, po prvih 29 letih raziskovanja znani iz le \u0161tirih izvirov. Prav zaradi te ozke raz\u0161irjenosti jo za vedno lahko izbri\u0161e \u017ee lokalno onesna\u017eenje.<\/p>\n

“Da bi lahko na\u010drtovali u\u010dinkovito varstvo, moramo najprej natan\u010dneje poznati njeno raz\u0161irjenost. Pri \u010drni \u010dlove\u0161ki ribici res \u0161teje vsak dodatno odkriti izvir, \u010das pa te\u010de,” poudarja Aljan\u010di\u010d.<\/p>\n

V Beli krajini so z omenjenim raziskovalnim orodjem ugotovili, da se \u010drna \u010dlove\u0161ka ribica skriva \u0161e za petimi dodatnimi izviri. Kljub pove\u010danju \u0161tevila lokalitet pa so vse omejene na manj kot tri kvadratne kilometre plitvega belokranjskega krasa.<\/p>\n

“Ker gre za kmetijsko izjemno obremenjeno obmo\u010dje, je \u010drni proteus veliko bolj ogro\u017een, kot smo domnevali do sedaj,” opozarja vodja raziskave.<\/p>\n

Najve\u010dje presene\u010denje pa je po njegovih pojasnilih razkritje, da sta populaciji \u010drne in bele \u010dlove\u0161ke ribice vendarle v stiku, \u010deprav le v majhnem robnem podzemlju. “Prvi\u010d smo lahko pokazali, da je \u010drna \u010dlove\u0161ka ribica morda \u017ee samostojna vrsta.”<\/p>\n

V najobse\u017enej\u0161i terenski preiskavi raz\u0161irjenosti \u010dlove\u0161ke ribice doslej – 95 kra\u0161kih izvirov, vodnjakov in jam v obdobju 2013-2016 – so sicer raziskovalci iz Jamskega laboratorija Tular prvi\u010d podalj\u0161ali njeno ju\u017eno mejo v \u010crno goro.<\/p>\n

Inovativna metoda pa ni pomembna le za razvoj jamske biologije in varstva \u010dlove\u0161ke ribice, tak\u0161en pristop omogo\u010da iskanje redkih in ogro\u017eenih \u017eivalskih vrst tudi drugje po svetu.<\/p>\n

Po slovenskem zgledu \u017ee i\u0161\u010dejo zadnje pre\u017eivele primerke \u017eelve jangce\u0161ke orja\u0161ke mehko\u0161\u010ditke v Vietnamu, \u0161e navajajo v Jamskem laboratoriju Tular.<\/p>\n

V projektu so kot partnerji sodelovali \u0161e Biotehni\u0161ka fakulteta Univerze v Ljubljani, Biolo\u0161ki in\u0161titut ZRC Sazu in Univerza v Marylandu, ob terenski podpori Biospeleolo\u0161kega dru\u0161tva \u010crne gore.<\/p>\n","protected":false},"excerpt":{"rendered":"
