Isishwankathelo
Ukwahlukana kwezesondo ngobukhulu bomzimba phakathi kweentaka zaselunxwemeni kudla ngokunxulunyaniswa nemisebenzi yokuzala, kodwa umahluko onjalo unokukhokelela kumahluko kwindalo ngexesha eliseleyo lomjikelo wonyaka. Apha, siphanda ukuba iinkunzi ezincinci kunye neemazi ezinkulu zeBohai Black-tailed Godwits Limosa limosa bohaii zahlukile na kwindlela ezisetyenziswa ngayo kwiindawo zokuhlala kunye nokuziphatha okunentsingiselo njengoko zigcwalisa umbane kunxweme lwaseTshayina ngexesha lokufuduka emantla. Ngokusekelwe ekubonweni okubonakalayo, ukwanda kweeprofayili zesisu kuqinisekisile ukugcwaliswa kwazo umbane kwindawo yokufunda yaseBohai Bay. Sisebenzisa i-GPS telemetry, sifumanise ukuba iinkunzi zazihlala kakhulu kwiindawo ezilunxwemeni nakwiindawo zetyuwa ezikufutshane, ngelixa iimazi zazisebenzisa uluhlu olubanzi lweendawo zokuhlala, kubandakanya amanzi acocekileyo kunye nemigxobhozo yetyuwa ngakumbi ngaphakathi. Ekupheleni kuka-Epreli nasekuqaleni kukaMeyi, iimazi zatshintshela ngokuthe ngcembe kwezi ndawo zokuhlala ngaphakathi. Ukulinganiswa kwe-Accelerometry kubonisa ukuba kwiindawo ezilunxwemeni, iinkunzi kunye neemazi zazinamandla aphezulu okuhambahamba zijikeleze amaza aphezulu. Sitolika oku njengokubonakaliswa kokungaphumli kwazo ngexesha leeyure ezazixinaniswe kwiindawo ezincinci zonxweme ezikufutshane nomsebenzi omkhulu wabantu. Kwiindawo zokuhlala ezingaselunxwemeni, ezi zini zimbini zibonakalise isigqi esifanayo nesicacileyo somsebenzi wemihla ngemihla, kunye nokuncipha kwamandla okuhamba kwiiyure zasebusuku ngaphambi kokuphuma kwelanga. Amandla okuhamba kwiindawo zokuhlala ezingaphakathi aphinda kabini lawo akwiindawo ezimdaka, mhlawumbi ebonisa umsebenzi ophezulu wokufuna ukutya ofunekayo ukuze kwaneliswe iimfuno zokutya ngenxa yezilwanyana ezincinci ezidla i-arthropod emasimini erayisi (izibungu zeChironomid) kunye ne-saltworks (izibungu ze-brine fly), xa kuthelekiswa nezilwanyana ezinkulu ezidla i-polychaete kwiindawo ezimdaka.
