Isishwankathelo:
Amanyathelo okugcina asebenzayo axhomekeke kakhulu kulwazi lokukhetha iindawo zokuhlala zeentlobo ekujoliswe kuzo. Kuncinci okwaziwayo malunga neempawu zesikali kunye nesingqisho sexesha lokukhetha indawo yokuhlala yekreyini esengozini yokutshabalala, nto leyo ethintela ukugcinwa kwendawo yokuhlala. Apha, iikreyini ezimbini ezibomvu zilandelwe ngenkqubo yeGlobal position (GPS) kangangeminyaka emibini eYancheng National Nature Reserve (YNNR). Indlela ye-multiscale yaphuhliswa ukuchonga ipateni yendawo yokukhetha indawo yokuhlala yeekreyini ezibomvu. Iziphumo zityhile ukuba iikreyini ezibomvu zikhetha ukukhetha iScirpus mariqueter, amachibi, iSuaeda salsa, kunye nePhragmites australis, kwaye ziphephe iSpartina alterniflora. Kwixesha ngalinye lonyaka, umlinganiselo wokukhetha indawo yokuhlala yeScirpus mariqueter kunye namachibi wawuphezulu emini nasebusuku, ngokwahlukeneyo. Uhlalutyo olongezelelekileyo lwezikali ezininzi lubonise ukuba ipesenti yokugubungela i-Scirpus mariqueter kwisikali se-200-m ukuya kwi-500-m yayiyeyona nto ibalulekileyo kuzo zonke iindlela zokukhetha indawo yokuhlala, igxininisa ukubaluleka kokubuyisela indawo enkulu yendawo yokuhlala ye-Scirpus mariqueter yokubuyisela inani lee-crane ezibomvu. Ukongeza, ezinye izinto eziguquguqukayo zichaphazela ukhetho lweendawo zokuhlala kwizikali ezahlukeneyo, kwaye igalelo lazo liyahluka ngokwexesha lonyaka kunye ne-circadian rhythm. Ngaphezu koko, ukufaneleka kwendawo yokuhlala kwadweliswa ukuze kubonelelwe ngesiseko esithe ngqo solawulo lweendawo zokuhlala. Indawo efanelekileyo yendawo yokuhlala yasemini nasebusuku yayibalelwa kwi-5.4%–19.0% kunye ne-4.6%–10.2% yendawo yophando, ngokulandelelana, nto leyo ebonisa ukungxamiseka kokubuyiselwa. Olu phononongo lugxininise isikali kunye nesantya sexesha sokukhethwa kwendawo yokuhlala kwiintlobo ezahlukeneyo ezisengozini ezixhomekeke kwiindawo ezincinci zokuhlala. Indlela ecetywayo yezikali ezininzi isebenza ekubuyiselweni nasekulawulweni kweendawo zokuhlala zeentlobo ezahlukeneyo ezisengozini.
