Ukuzwa kude kanye nokulandelela nge-GPS kwembula ukushintsha kwesikhashana kokusetshenziswa kwezindawo zokuhlala kuma-Black-tailed Godwits angazalani

Ijenali:I-Ecology Esetshenziswayo

Uhlobo (ilulwane):Ama-Godwit anemisila emnyama

Isifinyezo:

1. Ulwazi lwezidingo zendawo yokuhlala yezinhlobo ezifudukayo kulo lonke umjikelezo wazo waminyaka yonke luyadingeka ezinhlelweni eziphelele zokuvikela izinhlobo. Ngokuchaza ukushintsha kwesizini kwamaphethini okusetshenziswa kwesikhala endaweni ebalulekile engazalani, iSenegal Delta (eMauritania, eSenegal), lolu cwaningo lubhekana negebe elikhulu lolwazi emjikelezweni waminyaka yonke we-Continental Black-tailed Godwit encipha ngokushesha.I-limosa limosa.
2. Sifake amamodeli okunyakaza kwenqubo ye-stochastic yesikhathi esiqhubekayo nedatha yendawo ye-GPS ukuchaza izindawo eziyinhloko ezisetshenziswa ama-godwit angu-22 ane-GPS-tagged esikhathini sokungazali sika-2022-2023. Sidwebe izinhlobo ezibalulekile zezindawo zokuhlala, njengezindawo ezimanzi ezikhukhula kanye namasimu elayisi, ngokuhlukaniswa okuqondisiwe kwezithombe zesathelayithi.
3. Ama-Godwits aseSenegal Delta abonisa ushintsho oluhlukile ekusetshenzisweni kwezindawo zokuhlala phakathi nesikhathi sokungazali. Izindawo eziyinhloko zama-godwits ezigabeni zokuqala zesikhathi sokungazali (isizini yemvula) zazitholakala kakhulu ezindaweni ezimanzi zemvelo nasemasimini anelayisi elisanda kutshalwa. Njengoba isivuno serayisi sikhula futhi siba siningi kakhulu, ama-godwits athuthela emasimini elayisi asanda kutshalwa. Kamuva, njengoba amanzi ezikhukhula ehla futhi amasimu elayisi oma, ama-godwits ashiya amasimu elayisi futhi athuthela ezindaweni ezimanzi zemvelo ezinezitshalo ezimbalwa ezihlaselayo, ikakhulukazi ngaphakathi kwamaxhaphozi kanye nezindawo ezimanzi ezingajulile zezindawo ezivikelwe imvelo e-Delta engezansi.
4. Ukwenziwa kanye nezinhlelo zokusebenza: Okutholakele kwethu kubonisa ukubaluleka okushintshashintshayo kwezindawo ezimanzi zemvelo nezolimo zama-godwits ezigabeni ezahlukene zesizini yokungazali. Izindawo ezivikelwe eSenegal Delta, ikakhulukazi i-Djoudj National Bird Sanctuary (Senegal) kanye ne-Diawling National Park (Mauritania), ziyizindawo ezibalulekile zokuhlala ngesikhathi sesomiso njengoba ama-godwits elungiselela ukufuduka kwawo enyakatho, kuyilapho amasimu elayisi edlala indima ebalulekile ngesikhathi semvula. Imizamo yokulondoloza kufanele ibeke phambili ukuqeda izitshalo ezihlaselayo ezivela e-Djoudj nase-Diawling, kanye nokukhuthaza ukuphathwa kwezolimo ezindaweni ezithile zokukhiqiza ilayisi eziboniswe kulolu cwaningo.
