Rudzi: Limosa limosa bohaii
Pfupiso
Kusiyana kwehunhu hwemuviri pakati peshiri dzemumahombekombe kunowanzobatanidzwa nebasa rekubereka, asi kusiyana kwakadaro kunogonawo kukonzera kusiyana kwezvakatipoteredza panguva yasara yegore negore. Pano, tinoongorora kana shiri diki neshiri dzemugungwa dzeBohai Black-tailed Godwits Limosa limosa bohaii dzakasiyana mukushandiswa kwenzvimbo uye maitiro ekumhanya sezvadzinodira mafuta mumahombekombe eChina panguva yekufamba kwekuchamhembe. Zvichibva pakuona kwadzinoita, kuwedzera kwehuwandu hwedumbu kwakasimbisa kudira kwadzo mafuta munzvimbo yekudzidza yeBohai Bay. Tichishandisa GPS telemetry, takaona kuti shiri dzemukomana dzaiwanzowanikwa munzvimbo dzine madhaka egungwa nenzvimbo dziri pedyo nemunyu, nepo shiri dzemukomana dzaishandisa nzvimbo dzakasiyana-siyana, kusanganisira mvura yakachena uye mvura ine saline mukati menyika. Pakupera kwaKubvumbi nekutanga kwaChivabvu, shiri dzemukomana dzakachinja zvishoma nezvishoma kuenda kunzvimbo idzi dziri mukati menyika. Kuyerwa kweAccelerometry kunoratidza kuti munzvimbo dzine madhaka, shiri dzemukomana nedzemukomana dzaive nesimba guru rekufamba dzakatenderedza mafungu. Tinodudzira izvi sechiratidzo chekusagadzikana kwavo mumaawa avaidzvinyirirwa munzvimbo diki dzemahombekombe dziri pedyo nemabasa evanhu. Munzvimbo dzisiri dzemahombekombe, mhando mbiri idzi dzechikadzi nedzechikadzi dzakaratidza kufamba kwakafanana uye kwakajeka kwezuva, nekufamba kwakaderera mumaawa ehusiku zuva risati rabuda. Kufamba kwakawanda munzvimbo dziri mukati megungwa kunowedzera kaviri kupfuura kuri munzvimbo dzine matope, zvichida zvichiratidza kushanda kwakawanda kwekutsvaga chikafu kunodiwa kuti zvigutse zvinodiwa nekuda kwekudya kudiki kwemhuka dzinonzi arthropod dziri muminda yemupunga (Chironomid larvae) uye munyu (brine fly larvae), zvichienzaniswa nemhuka huru dzinonzi polychaete dziri munzvimbo dzine matope.
