Inzwa ekude kanye nokulandelela i-GPS kuveza ukushintsha kwesikhashana ekusetshenzisweni kwendawo yokuhlala kuma-Godwits angazalisi ama-Black-tailed

Ijenali:I-Ecology Esetshenziswayo

Izinhlobo (ilulwane):AmaGodwits anomsila omnyama

Abstract:

1. Ulwazi lwezidingo zendawo yokuhlala zezinhlobo ezifudukayo kuwo wonke umjikelezo wazo waminyaka yonke luyadingeka ezinhlelweni ezibanzi zokuvikela izinhlobo. Ngokuchaza ukushintsha kwenkathi ethile yamaphethini okusetshenziswa kwendawo endaweni eyinhloko engazalisi, i-Senegal Delta (Mauritania, Senegal), lolu cwaningo lubhekana negebe elibalulekile lolwazi emjikelezweni waminyaka yonke we-Godwit yezwekazi elimnyama ewohloka ngokushesha.Limosa lilimosa.
2. Sifake amamodeli okunyakaza kwenqubo ye-stochastic yesikhathi esiqhubekayo nedatha yendawo ye-GPS ukuchaza izindawo ezibalulekile ezisetshenziswa ama-godwits ama-GPS angama-22 esikhathini sika-2022–2023 sokungazaleli. Senze imephu yezinhlobo zezindawo zokuhlala ezibalulekile, njengamaxhaphozi e-floodplain namasimu elayisi, ngokuhlukaniswa ngezigaba okugadiwe kwesithombe sesathelayithi.
3. Ama-Godwits e-Senegal Delta abonisa ushintsho oluhlukile ekusetshenzisweni kwendawo yokuhlala esikhathini esingazalisi. Izindawo eziyinhloko zama-godwits ezigabeni zokuqala zenkathi yokungazali (inkathi yemvula) ngokuyinhloko zazisezindaweni ezingamaxhaphozi zemvelo nasemasimini anerayisi esanda kutshalwa. Njengoba isivuno serayisi sikhula futhi siminyene kakhulu, ama- godwit athuthela emasimini erayisi asanda kutshalwa. Kamuva, njengoba amanzi ezikhukhula ayebohla namasimu elayisi oma, ama-godwit ashiya amasimu elayisi futhi ashintshela emaxhaphozini emvelo anezitshalo ezimbalwa ezihlaselayo, ikakhulukazi phakathi kwamaxhaphozi kanye nezikhukhula ezingajulile zezindawo ezivikelwe imvelo endaweni engaphansi kweDelta.
4. Synthesis kanye nezicelo: Esikutholile kukhombisa ukushintsha kokubaluleka kwamaxhaphozi emvelo kanye nezolimo kuma-godwits ezigabeni ezahlukene zenkathi yokungazali. Izindawo ezivikelekile e-Senegal Delta, ikakhulukazi i-Djoudj National Bird Sanctuary (Senegal) kanye ne-Diawling National Park (Mauritania), ziyizindawo zokuhlala ezibalulekile ngenkathi eyomile njengoba ama-godwit elungiselela ukufudukela enyakatho, kuyilapho amasimu elayisi ebamba iqhaza elikhulu ngesikhathi semvula. Imizamo yokulondoloza kufanele ibeke eqhulwini ukuqeda izitshalo ezihlaselayo ku-Djoudj ne-Diawling, kanye nokukhuthaza ukuphathwa kwe-agroecology ezindaweni ezithile zokukhiqiza irayisi eziboniswe kulolu cwaningo.
