I-merganser yaseBrazil (i-Octosetaceus mergus) ingeyomndeni wedada, i-oda le-Anseriformes.
Izimpawu zangaphandle ze-merganser yaseBrazil
I-Merganser yaseBrazil yidada elimnyama, elizacile elinesisindo esiphakathi esilingana no-49-56 cm. Isigqoko esimnyama esibonakalayo esinokukhanya okusansimbi okuluhlaza okotshani. Isifuba simpunga okhanyayo, sinamabala amancane amnyama, ngezansi kombala siba sincane bese siphenduka isisu esimhlophe. Okuphezulu kumnyama mpunga. Izimpiko zimhlophe, zinwetshiwe. Umlomo winde, umnyama. Imilenze ibomvana ne-lilac. Isigaxa eside, esinyene, kuvamise ukuba mfushane kowesifazane.

Kungani i-merganser yaseBrazil isengozini?
Ama-mergansers aseBrazil asengcupheni yokuqothulwa. Amarekhodi akamuva avela eBrazil akhombisa ukuthi isimo salesi silwane singaba ngcono kancane kunalokho obekucatshangwa ngaphambili. Kodwa-ke, abantu abasele abaziwayo basebancane kakhulu futhi bahlukaniswe kakhulu. Ukuba khona kwamadamu nokungcola kwemifula kungenzeka kube yizimbangela ezinkulu zokwehla kwamanani okuqhubekayo. Abahlanganisi baseBrazil bahlala ngamanani aphansi kakhulu endaweni ehlukaniswe kakhulu eningizimu nasenkabeni yeBrazil. Amadada angavamile atholakala eSerra da Canastra Park, lapho abonwa khona endaweni elinganiselwe.
Emithanjeni yeRio San Francisco eya eWest Bahia, abahlanganisi baseBrazil abakatholakali. Muva nje, amadada angavamile atholakele kumasipala wasePatrosinio, eMinas Gerais, kepha ngokusobala lezi bekuyizikhathi ezithile ezindiza ngezinyoni. Abahlanganisi baseBrazil nabo bahlala endaweni eseduze nepaki eRio das Pedras. Inani elincane labantu baseBrazil Mergansers latholakala ngo-2002 eRio Novo, eJalapão Park, esifundazweni saseTocantins.
Amabhangqa amathathu okuzalanisa abonwa ngaphezu kwamakhilomitha angama-55 eRio Nova, kanti amabhangqa amane abonwa ngamakhilomitha ayi-115 ukusuka edolobheni ngo-2010-2011.
E-Argentina, eMisiones, kwatholakala abantu abangu-12 e-Arroyo Uruzú ngo-2002, okuyirekhodi lokuqala eminyakeni eyishumi, naphezu kocwaningo olunzulu endaweni.
EParaguay, abahlanganisi baseBrazil ngokusobala bashiye lezi zindawo zokuhlala. Ngokwezibalo zakamuva, zenzeka ezindaweni ezintathu eziyinhloko ezindaweni ezingama-70-100. Isibalo samadada angavamile njengamanje asidluli kubantu abavuthiwe abangama-50-249.
Izindawo zokuhlala ze-merganser yaseBrazil
Abahlanganisi baseBrazil bahlala emifuleni engajulile, esheshayo enama-rapids namanzi acwebile. Bakhetha imingenela engenhla yomfula wamanzi, kepha futhi bahlala emifuleni emincane enezindawo zamahlathi ezibukiswe yi "serrado" (ama-savanna asezindaweni ezishisayo) noma ehlathini lase-Atlantic. Kuyisilwane esihlala phansi, futhi esigabeni somfula, izinyoni zakha indawo yazo.
Ukuzalisa i-Merganser yaseBrazil
Amabili ama-mergansers aseBrazil okwakha izidleke akhetha indawo enamakhilomitha ayi-8-14 ubude. Indawo yokuhlala ithatha ukuba khona kwama-rapids amaningi emfuleni, imisinga enamandla, ubuningi nokulondolozwa kwezimila. Isidleke sihlelwe ngemigodi, emifantwini, ezindaweni ezibekiwe osebeni lomfula. Isikhathi sokuzalisa nguJuni nango-Agasti, kepha isikhathi singahluka ngokuya ngendawo. Ukufukamela kuthatha izinsuku ezingama-33. Izinyoni ezincane zibonakala kusukela ngo-Agasti kuya kuNovemba.
Ukudla kweBrazil Merganser
Ama-mergansers aseBrazil adla izinhlanzi, ama-eel amancane, izibungu zezinambuzane, izimpukane neminenke. E-Serra da Canastra, izinyoni zidla i-lambari.
Izizathu zokwehla kwenani le-merganser yaseBrazil
Isibalo sabakwa-Merganser baseBrazil besincipha ngokushesha kule minyaka engama-20 edlule (izizukulwane ezintathu), ngenxa yokulahleka nokonakala kwezindawo zokuhlala ebangeni, kanye nokwandiswa kokwakhiwa kwezikhungo zokuphehla ugesi ophehlwa ngamanzi, ukusetshenziswa kwezindawo zokutshala ubhontshisi wezimayini nowezimayini.
Mhlawumbe i-merganser yaseBrazil isasinda ezindaweni ezingenamithi, ezingathintwanga eceleni komfula eCerrado.
Ukungcoliswa komfula kusuka ekuqothulweni kwamahlathi nokwanda kwemisebenzi yezolimo endaweni yaseSerra da Canastra kanye nezimayini zedayimane kuholele ekwehleni kwenani labahlanganisi baseBrazil. Phambilini, lolu hlobo lwalucasha emahlathini egalari, okwakuthi noma luvikelwe ngumthetho eBrazil, kepha lusetshenziswe ngokungenasihawu.
Ukwakhiwa kwedamu sekuvele kudale umonakalo omkhulu ezindaweni ezihlanganisiwe kulo lonke uhla.
Imisebenzi yezivakashi ezindaweni ezaziwayo naphakathi kwamapaki kazwelonke yandisa ukukhathazeka.
Izinyathelo zokuvikelwa kwe-merganser yaseBrazil
Ama-Mergansers aseBrazil avikelwe ezindaweni zokupaka ezintathu zaseBrazil, ezimbili zazo ezomphakathi kanti eyodwa iyindawo evikelekile yangasese. Sekushicilelwe uhlelo lwezenzo zokongiwa kwemvelo oluchaza ngesimo samanje se-Merganser yaseBrazil, imvelo yezinto eziphilayo, izinsongo nezinyathelo ezihlongozwayo zokongiwa kwemvelo. E-Argentina, ingxenye ye-Arroyo Uruzú ye-merganser yaseBrazil ivikelwe e-Uruguaí Provincial Park. I-Serra da Canastra ihlolwe njalo.
Epaki lesizwe eBrazil, kuye kwakhishwa abantu abangu-14, futhi abahlanu babo bathole imishini yokusakaza ukulandelela ukuhamba kwezinyoni. Izidleke zokufakelwa zifakiwe endaweni evikelekile. Ucwaningo lwezofuzo luyaqhubeka kubantu, okuzofaka isandla ekulondolozweni kwezinhlobo. Uhlelo lokuzalela abathunjwa olwaqala ngo-2011 edolobheni lasePocos de Caldes esikhungweni sokuzalela eMinas Gerais sikhombisa imiphumela emihle, ngamadada amaningi amancane akhuliswa ngempumelelo futhi adedelwa endle. Amaphrojekthi wemfundo yezemvelo aqale ukusetshenziswa kusukela ngo-2004 eSan Roque de Minas naseBonita.
Izindlela zokongiwa kwemvelo zifaka phakathi ukuhlola isimo sezinhlobo eziseSerra da Canastra nokwenza ucwaningo esifundeni saseJalapão ukuthola abantu abasha. Qhubeka nokwenziwa nokusetshenziswa kwezindlela zocwaningo kusetshenziswa izithombe zesathelayithi. Ukuvikelwa kwemithombo yamanzi nezindawo zemifula yabantu kuyadingeka, ikakhulukazi eBahia. Ukuqwashiswa kwabantu bendawo ukuqinisekisa imibiko yendawo yokuba khona kwalezi zinhlobo ezingavamile. Nweba insimu yepaki kazwelonke eBrazil. Qhubeka nohlelo lokuzalisa abathunjiwe baseBrazil Mergansers. Ngo-2014, imiyalo yokulawula yamukelwa evimbela noma yimuphi umsebenzi ezindaweni lapho kutholakala khona abahlanganisi baseBrazil.
