Abstract:

1. Ruzivo rwezvinoda pekugara kune mhuka dzinotama mukati menguva yadzo yegore rose inodiwa pahurongwa hwekuchengetedza marudzi. Nekutsanangura shanduko dzemwaka dzemashandisirwo emuchadenga munzvimbo yakakosha isingabereki, Senegal Delta (Mauritania, Senegal), chidzidzo ichi chinogadzirisa gaka rakakosha reruzivo mukutenderera kwegore kweiyo inokurumidza kudzikira kondinendi yeBlack-tailed Godwit.Limosa limosa limosa.
2. Isu takaisa inoenderera-nguva stochastic-maitiro ekufamba modhi neGPS nzvimbo data kutsanangura nzvimbo dzepakati dzinoshandiswa nemakumi maviri nembiri GPS-akaiswa magodwits mukati menguva ya2022-2023 yekusabereka. Takaronga marudzi akakosha enzvimbo, senge madonhwe emvura neminda yemupunga, tichishandisa kupatsanurwa kwemifananidzo yesatellite.
3. Godwits muSenegal Delta inoratidza shanduko yakasiyana mukushandiswa kwekugara panguva yekusaberekana. Nzvimbo dzepakati dzegodwits munhanho dzekutanga dzenguva yekusaberekesa (mwaka wemvura) dzaive zvakanyanya munzvimbo dzakasikwa dzakanyorova uye minda ine mupunga uchangorimwa. Sezvo mupunga waikura uye wakanyanya kuoma, godwit dzakatamira kuminda yemupunga yakanga ichangodyarwa. Gare gare, mvura yemafashamo payakaserera uye minda yemupunga yaoma, godwit dzakasiya minda yemupunga ndokutamira kunzvimbo dzakasikwa dzine zvirimwa zvishoma, kunyanya mumadhaka uye nzvimbo dzisina kudzika dzemafashamo enzvimbo dzakachengetedzwa zvisikwa muzasi Delta.
4. Synthesis uye kushandiswa: Zvatakawana zvinoratidza kuchinja kwekukosha kwematoro echisikigo uye ekurima kune godwit panguva dzakasiyana dzemwaka usingabereki. Nzvimbo dzakadzivirirwa muSenegal Delta, kunyanya Djoudj National Bird Sanctuary (Senegal) neDiawling National Park (Mauritania), inzvimbo dzakakosha dzekugara munguva yekusanaya kwemvura sezvo godwit dzinogadzirira kutamira kuchamhembe, ukuwo minda yemupunga ichiita basa rakakosha munguva yemvura. Kuedza kuchengetedza kunofanirwa kukoshesa kubvisa zvirimwa zvinoparadza kubva kuDjoudj neDiawling, pamwe nekusimudzira manejimendi ezvekurima mumichero yekugadzira mupunga inoratidzwa muchidzidzo chino.
