Ucwaningo lwamuva nje olushicilelwe kumagazini i-"Biological Conservation" mayelana nokubeka engozini izimvemvane esifundeni sase-Alpine lubonisa ngokumangalisayo ukuthi ukulahlekelwa kwezinto eziphilayo kuyaqhubeka kakhulu, ikakhulukazi ezindaweni eziphansi, ezisetshenziswa kakhulu . Ososayensi ababambe iqhaza abavela eNyuvesi yaseSalzburg, eSalzburg Nature Center, kanye naseSenckenberg Society for Natural Research basekela kakhulu ukwakhiwa kwezindawo ezivikelwe ezindaweni zasezigodini - noma ngabe lokhu kubonakala kuphikisana nezintshisekelo zomnotho ekuqaleni.
I-Large Pearl-bordered Fritillary ( Boloria eunomia ), i-Purple-edged Copper ( Lycaena hippothoe ), kanye ne-Large Blue ( Glaucopsyche alexis ) – lawa mavemvane aphakathi kwezinhlobo ezisengozini yokuqothulwa esifundazweni sase-Austria iSalzburg. "Amavemvane ayizinkomba ezinhle kakhulu nezithembekile zezinguquko ezindaweni zemvelo," kuchaza uSolwazi uDkt. Thomas Schmitt waseSenckenberg German Entomological Institute eMüncheberg naseNyuvesi yasePotsdam, eqhubeka: "Noma kunjalo, ukwehla kokuhlukahluka kwamavemvane ezingxenyeni ezinkulu ze-Central Europe kuze kube manje akukabhalwa ngokwanele. Manje sesikwazile ukuvala leli gebe esifundazweni saseSalzburg."
Ngenxa yale njongo, isazi sezinambuzane saseMünchberg, kanye noSolwazi uDkt. Werner Ulrich waseNicolaus Copernicus University eToruń, uSolwazi uDkt. Jan Christian Habel waseNyuvesi yaseSalzburg, kanye noDkt. Patrick Gros waseNdlu Yemvelo eSalzburg, bahlaziye idatha yesikhathi eside eyingqayizivele, yokubuka komuntu ngamunye okungaphezu kuka-250.000 okuvela esifundazweni saseSalzburg. Le datha ihlanganisa isikhathi kusukela ngo-1900 kuya ku-2022. Ucwaningo lwenziwe kuphrofayela ebanzi yokuphakama esukela kumamitha angu-380 kuya kwangu-3.105.
“Ukwaziswa kubonisa ngokusobala ukuthi usongo olukhulu luthinta izinhlobo zezimvemvane ezitholakala ezindaweni eziphansi, ikakhulukazi lezo ezithembele endaweni ezungezile engenazo izakhi noma izindawo ezihlala izilwane ezifuywayo namaxhaphozi,” kuchaza uHabel, enezela: “Izinhlobo eziningi zezinto eziphilayo manje eseziyivelakancane zitholakala ezindaweni eziphakeme kuphela, kuyilapho izinhlobo eziningi ezisengozini yokushabalala.”
Izinhlobo zovemvane eziyi-147 ezihlolisisiwe zasatshalaliswa ngokuhlukile endaweni yokuphakama kuye ngesimo sazo sosongo: Izinhlobo ezisengozini yokushabalala zazitholakala kakhulu ngaphansi kwamamitha angu-800. Izinhlobo ezisabalele kakhulu, ngokuphambene, zazitholakala kaningi ngaphezu kwamamitha ayi-1.500, isilinganiso esingaphezu kwamamitha angama-600. Abacwaningi bachaza lo mehluko phakathi kwezindawo eziphansi nezintaba ngokukhula kwengcindezi evela kwezolimo kanye nokusetshenziswa komhlaba ezigodini.
Kuyakhathaza futhi ukuthi ngaphezu kwamaphesenti angama-90 ezindawo ezivikelekile zase-Salzburg zitholakala ngaphezu kokuphakama okungamamitha ayi-1.000. UGros uyaxwayisa: “Nokho, ezigodini izindawo zokugcina zezimvemvane ziya ziba ngokungalingani, ngokuyinhloko ngenxa yezolimo ezinkulu, eziqinile, nezingakhethi lapho. Ngisho noma ukuvikelwa okungokomthetho kwamamoor kuye kwasiza izimvemvane ezithile ezindaweni eziphansi ezisebenza ngokukhethekile kulezi zindawo zokuhlala, isimo sezilwane ezihlala ezindaweni ezifudumele nezimpofu ngokuvamile siba nzima kakhulu.” USchmitt uyanezela: "Kuwumsebenzi wosopolitiki ukulwa nalesi simo. Ukuvikela okuphumelelayo kwezinhlobonhlobo zezinto eziphilayo ezindaweni ezisemathafeni - ngokwesibonelo esifundeni saseFlachgau - ngamasu amasha okongiwa kwemvelo kanye nezolimo ezilungele ukuhlukahluka kwemvelo sekuyisikhathi eside sadlula."
Ososayensi abathathu bavumelana ngokuthi: Ukongiwa kwemvelo ngeke kusakhawulelwa ezindaweni lapho izithakazelo zezomnotho zingathinteki khona. Phela, imvelo engaguquki akuzona kuphela izindawo zokuhlala zezilwane nezitshalo - futhi ziyisisekelo sezinga lethu lempilo kanye nokuzinza kwezomnotho kwesikhathi eside. "Ukucabanga kabusha kuyadingeka," umyalezo ocacile wababhali bocwaningo. "Ukongiwa kwemvelo akufanele kubonwe njengesithiyo, kodwa njengethuba - lekusasa elifanele ukuphila kwethu sonke."
