ʻAno (Avian):ʻO ka kuisa keʻokeʻo mua loa (Anser albifrons)
Puhi:
ʻO ka hāʻawi ʻana i nā kumuwaiwai meaʻai he kumu nui i ke koho ʻana i kahi noho. ʻOi aku ka makemake o nā manu wai herbivorous i nā mea kanu ulu mua (mai ka hoʻomaka ʻana o ka ulu ʻana o ka mea kanu a hiki i ka piko o ka biomass nutrient) no ka mea, hāʻawi kēia i ka nui o ka ikehu. ʻAʻole i paʻa pono kēia pae hoʻomohala ʻana i nā mea kanu e nā hōʻailona mea kanu i loaʻa i ka satellite, e kālele ana i ka biomass mea kanu (e laʻa, Enhanced Vegetation Index, EVI) a i ʻole ka ulu ʻana o ka mea kanu (e laʻa, ka EVI ʻokoʻa ma waena o kēia manawa a me ka lā mua, diffEVI). No ka hoʻomaikaʻi ʻana i ka palapala ʻana i nā wahi ʻai kūpono no nā moa wai herbivorous, ke hāpai nei mākou i kahi hōʻailona ulu mea kanu ma muli o ka satelite no ka ulu mua ʻana o nā mea kanu (ESPG). Manaʻo mākou he makemake nā manu wai herbivorous i nā mea kanu i ka wā ulu mua i ka wā ulu a koho i nā mea kanu me ka hopena hope loa o ESPG i ka wā ulu ʻole. Hoʻohana mākou i ka ʻikepili ukali ukali o 20 mau geese keʻokeʻo mua (Anser albifrons) i ka hoʻoilo ma ke kahawai ʻo Yangtze e hōʻoia i kā mākou wānana. Kūkulu mākou i nā hiʻohiʻona laina laulā no ka hāʻawi ʻana i ka kuihi i ka wā ulu a ulu ʻole a hoʻohālikelike i ka hana o ESPG me nā mea hōʻailona ulu ulu maʻamau (EVI a me diffEVI). I ka wā ulu, hiki i ka ESPG ke wehewehe i ka 53% o ka hoʻololi ʻana i ka puʻu kuihi, ʻoi aku ka maikaʻi o ka EVI (27%) a me ka diffEVI (34%). I ka wā ulu ʻole, ʻo ka hopena wale nō o ka ESPG ka mea nui i ka hoʻoili ʻana i ka kuihi, e wehewehe ana i ka 25% o ka ʻokoʻa (ESPG: AUC = 0.78; EVI: AUC = 0.58; diffEVI: AUC = 0.58). Hiki ke hoʻohana ʻia ka hōʻailona ulu ulu hou ʻo ESPG no ka hoʻomaikaʻi ʻana i nā hiʻohiʻona o ka hāʻawi ʻana i nā moa wai herbivorous a no laila ke kākoʻo nei i ka hoʻoikaika ʻana i ka mālama ʻana i nā moa wai a me ka hoʻokele wai.
