Indawo yobugebengu: indawo yokugcina imvelo ye-gypsum karst eduze kwase-Ührde. Nalapha futhi, cishe amamitha angu-600 ezimila ezisemaphethelweni ensimu anqunywa ngomshini wokugunda izihlahla, kulokhu endleleni yokuhamba ngezinyawo ngaphesheya komfula i-Rötzel. Ukusetshenziswa kwemishini yokugunda izihlahla ezimaphethelweni ezihlahleni endaweni yokugcina imvelo akunasizathu ngokombono wobuchwepheshe noma wokuziphatha, ngoba kubhubhisa ngqo izakhiwo ezivikelwe izindawo ezihloselwe ukuzilondoloza. Lapho amagatsha namahlumela enqunywa ezindaweni ezinkulu, akugcini nje ngokuba amanxeba amaningi abangelwa izitshalo, kodwa konke ukuphila okubambelele kukho - kusukela ezigabeni zezinambuzane ezihlala ebusika kuya ezicabucabu nasezilwaneni ezincane - kuyanqunywa ngokoqobo. Lobu budlova obusebenza ngomshini buphikisana ngqo nemigomo yokulondolozwa kwemvelo, okuthi ezindaweni zokugcina imvelo ngokuvamile kufaka phakathi ukukhuthazwa kwemiphetho ehlukahlukene ngokwesakhiwo, uthango, kanye nezihlahla zasensimini, kanye nokulondolozwa kwezinto ezindala nezinkuni ezifile.
Ngokombono wemvelo yezitshalo, umshini wokugunda utshani awukhiqizi ukusikeka okuqondile, kodwa kunalokho uveza imifantu engabonakali, imivimbo, kanye nokudabuka kwefayibha. Izindawo ezinkulu nezingcolile eziphumelayo ziyizindawo ezifanele zokungena kwesikhunta esibhubhisa izinkuni kanye nezinye izifo, okwenza buthaka amandla esikhathi eside ezihlahla. Lokhu kucindezeleka okwengeziwe kukhulu kakhulu ezindaweni ezivikelwe, lapho izihlahla ezihlala khona zivame ukuba yizinsalela zezakhiwo zomlando, ngoba azikwazi "ukukhokhelwa" esikhathini esifushane ngokutshala kabusha ngaphandle kokuphazamisa ukuqhubeka kwemvelo okusunguliwe. Ngaphezu kwalokho, ukucubungula okuphindaphindiwe emgqeni ofanayo wokusika kuholela ekutheni izihlahla zibe "nenkani": izihlahla ziguga engxenyeni engaphandle, zikhiqize izimbali nezithelo ezimbalwa, futhi zilahlekelwe yisakhiwo esiqondile esibalulekile ezinhlotsheni eziningi zezilwane.
Okuyinkinga kakhulu ezindaweni zemvelo ukulahleka kwezilwane ezidla izinambuzane ezincike emagatsheni angaphandle kanye namahlumela angaphansi komhlaba. Ama-lepidopteran amaningi kanye nezinye izinhlobo zezinambuzane zihlala ebusika njengamaqanda, izibungu, noma ama-pupae emagatsheni noma eduze kwendawo enezinkuni; umshini wokugunda utshani ubhubhisa lezi zigaba kulo lonke indawo, ngaleyo ndlela unciphise ngqo ukuhlukahluka kwezinhlobo zendawo kanye ne-biomass. Ezindaweni ezivikelwe lapho eziningi zalezi zinhlobo zibhalwe njengezinhlobo eziqondiwe noma ezilawulwayo, ukusetshenziswa kobuchwepheshe obunjalo kusebenza "njengokusethwa kabusha" kwaminyaka yonke kwezilwane ezidla izinambuzane, esikhundleni sokukhuthaza ukuthuthukiswa kwezindawo zemvelo ezihlelwe kahle, ezicebile ngezinhlobo kanye nezindawo zemvelo zamahlathi njengoba kuhlosiwe. Ngaphezu kwalokho, ungqimba olwengeziwe olujiyile lwezinto ezisikiwe lucindezela izitshalo ezisemaphethelweni ezimila utshani, okuqokonyiswa ezifundweni eziningi njengomthombo obalulekile wabathuthi bempova, izimbungulu zomhlabathi, kanye nezinye izilwane ezidla izinambuzane.
Izingodo ezigcinweni zemvelo azigcini nje ngokuba izindawo zokuhlala zezinambuzane kodwa futhi ziyizindawo zokuzalela nezokuphephela zezinhlobo eziningi zezinyoni. Ezinyonini ezihlala ezindlini zothango nasemagatsheni asensimini, emagatsheni aseceleni aphelele, isembozo somhlabathi ominyene, kanye nesilinganiso esilinganiselwe sesakhiwo esiminyene nesivulekile kubalulekile; lesi sakhiwo sibhujiswa ngokumbozwa okuphindaphindiwe, okunzima. Izindawo ezingaba khona zokuzalela zibhujiswa ngokushesha, futhi ukulahlekelwa yizinambuzane namajikijolo ngasikhathi sinye kunciphisa ukutholakala kokudla unyaka wonke. Kumalulwane, avame ukubalwa njengezinhlobo ezihlosiwe ezindaweni ezivikelwe, ezinqunyiwe ngokulinganayo, ezigobile kusho ukulahlekelwa yiziqondiso zokuqondiswa kanye nezindawo zokuzingela ezihlelwe kahle.
Ukusetshenziswa kwemishini yokugunda utshani emiseleni ezindaweni zokugcina imvelo kuyisibonelo esihle sokungaqondi kahle ukuphathwa ngobuchwepheshe: ngaphansi kwesimo "sokuhleleka," uhlelo oluyinkimbinkimbi kakhulu, olucebile ngezinhlobo luncishiswa lube yisakhiwo sezinsalela esinganakekelwa kahle nesimpofu. Ngokuphambene nalokho, ukuphathwa okunesibopho ngokwemvelo ezindaweni ezivikelwe kufanele kuthembele ekungeneleleni okukhethiwe okwenziwa ngesandla noma ngamasu athambile , futhi kufanele kuhlose ukugcwalisa izakhiwo ezikhona kunokuzibhubhisa ngokufaka umquba ophindaphindayo.
