Kukurukurirana
Iyi mhando yepink dolphin, semamwe ma dolphin, achashandisa nhevedzano yemuridzo we tonal kutaura. Kubudiswazve kweiyi nhevedzano yemanzwi kunobatanidzwa nenguva yainodzokera kumusoro. Nguva refu kunyura kusati kwaitwa, izvi zvine chekuita nekuferefeta kunoitwa nekudyisa nekuvhima. Kana iri yekuongorora kweacoustic, vakaratidza kuti manzwi akasiyana zvakanyanya nekuenderana neakajairika muridzo wehuwandu hwedelphinid. Kusanganisira nenzira iyi hama yayo, tucuxi.
Kugovera uye Kuwanda kwevanhu
Paunenge uchitaura nezve kugovera uye huwandu hwepink dolphin, ichavhara yakakura siyana yeruzivo uye kunyangwe ipapo pane isina kukwana data. Sezvakatsanangurwa pamusoro apa, iyo pink dolphin ndeimwe yehombe munzizi, uye ivo zvakare vakanyanya kuwanda. Izvi zvine kugovaniswa kwakakura mukati menzvimbo yavo yemvura yakachena. Dzinogona kuwanikwa dzakaparadzirwa munyika 6 dzeSouth America dzinoti; Bolivia, Brazil, Colombia, Ecuador, Peru neVenezuela. Saka kuvepo kwayo kunogona kuwanikwa munzvimbo inosvika mamirioni manomwe km².
Iwo akagovaniswa muRwizi rweAmazon yese uye madiki ayo makuru, anosanganisira madiki madiki nemadziva akatenderedza. Kubva pamuromo padyo neBelén kusvika kwayakabva munzizi dzeMarañón neUcayali muPeru. Vane miganhu inotarwa nemapopoma asingafambike, seaya enzizi Xingú neTapajós muBrazil uye mumvura isina kudzika. Pamusoro pezvo, nhevedzano yemvura zhinji uye mapopoma eRwizi rweMadeira zvakabatsira mukuparadzaniswa kwevanhu vanozivikanwa se subspecies I. g. boliviensis, iri kumaodzanyemba kweAmazon basin.
Iyo pink rwizi dolphin inogoverwa pamwe neOrinoco rwizi bheseni, kunze kwerwizi rweCaroní uye nechepamusoro perwizi rweCaura muVenezuela. Iyo chete yekubatanidza pakati peOrinoco neAmazon iri kuburikidza neCasiquiare chiteshi. Kugoverwa kwema dolphin munzizi nenzvimbo dzakapoteredza kuchaenderana nenguva yegore. Kana kuine mwaka wekusanaya kwemvura vanenge vachiiswa murwizi. Asi kana mwaka wemvura zhinji, apo nzizi dzinopfachukira, dzinopararira munzvimbo dzine mafashamo. Sezvineiwo nemasango (igapó) pamwe nebani rakazara nemvura.
Nezvekuferefeta kwakaitwa kuti vakwanise kutsvaga huwandu hwepink dolphin, zvave zvakaoma kuongorora data rakataurwa, izvi zvinokonzerwa nemusiyano mukuru wenzira inoshandiswa. Mukuferefeta kwakaitwa muchikamu cheRwizi rweAmazon runozivikanwa seRwizi rweSolimões, rwune kureba kwemakiromita 1200 rwuri pakati peguta reManaus neTabatinga.

Pink river dolphin inogona kuwanikwa kunyanya mubazi guru reRwizi rweAmazon, pedyo neFonte Boa, Brazil. Anogona kuonekwa munzvimbo dzakasiyana-siyana dzemafashamo, senge madhamu nematanho madiki. Iyi inzvimbo yakasikwa yepink dolphin gore rese. Mumabheseni enzizi umo pink dolphin inogona kucherechedzwa, nzvimbo dzese dzekugara dzinogona kuwanikwa. Mune izvi iwe unogona kutsvaga nzira huru dzenzizi, migero, miromo yematareji, madziva uye kupera kwemvura zhinji nemapopoma.
Chicharatidza izvi kushanduka kwemamiriro ekunze, izvi zvichakanganisa mwero wenzizi munguva yekunaya kwemvura uye kunyangwe panguva yekusanaya kwemvura gore rose. Zvese izvi zvinotarisa kuti ndedzipi nzvimbo dzinogona kugarwa uye dzine chikafu chekuvararamisa. Mumwaka wakaoma, zvienzaniso zvinowanikwa muhova huru. Izvi zvinodaro nekuti migero mipfupi haina kudzika uye madhamu ari pedyo nemiganhu yerwizi. Ichi ndicho chikonzero mhuka iyi ine mutoro wekutamira kunzvimbo dzine chikafu chakawanda.
Munguva yekunaya kwemvura, rwizi rwepink dolphin runogona kufamba zviri nyore kuenda kune madiki madiki. Vanogona kutotamira kumasango nemapani emvura. Kana vari varume nevakadzi, vane chido chikuru pavanosarudza pekugara. Somuenzaniso, kana vari varume, vanodzokera kunzira huru dzenzizi, apo mvura inoramba yakakwirira. Kana dziri hadzi, pamwe chete nembeu dzadzo, dzinogara kwenguva refu munzvimbo dzine mafashamo.
Iye zvino unogona kunge uchishamisika kuti sei amai nemhuru yavo vachigara kwenguva yakareba, nokuti izvi zvine zvikonzero zvakasiyana kana zvikonzero. Mvura yorudzi urwu, iyo yakadzikama zvikuru, inobvumira pwere kushandisa simba shoma, inovabvumira kuzorora, kuyamwisa uye inotovakurudzira kuwana zvokudya mumhoteredzo isinganyanyi kunetsa. Mhoteredzo iyi inenge iri kure neaya mafungu enzizi anogona kukanganisa kuberekesa. Zvinoderedza zvakare njodzi yehasha dzevarume kune vadiki uye kunyange kudzvinyirirwa nedzimwe mhuka parudzi urwu.
Kutama
MuPacaya Samiria National Reserve, iyo iri muPeru, pikicha-identification yakashandiswa kuitira kuziva zvienzaniso zviri kuongororwa. Vanoita izvi kuburikidza nemaitiro emavara, mavanga, uye kuchinjwa kwemuromo. 72 mienzaniso inogona kuwanikwa, iyo makumi maviri neshanu yaive iri pakati pe25 ne1991. Nguva pakati peimwe neimwe yekuona kwavo inoverengerwa kuti inosiyana pakati pe2000 zuva uye 1 kusvika 6 makore. Kana iri muganho wayo wepamusoro wekufamba, yaive ingangoita 7 km, ine avhareji ye120 km.
Zvinoenderana nezvidzidzo zvakaitwa pazvipenyu izvi, chinhambwe chikuru chakanyorwa muzuva rimwe chaive chingangoita 120 km, paine huwandu hwe14,5 km. Mune imwe ongororo yakaitwa pakati peRwizi rweAmazon, umo yakagadziridzwa pakati penzvimbo ino, zvaigoneka kuona kuti ma dolphin aifamba makumi mashoma emakiromita. Maitiro aya akaitika kupfuura chero chinhu pakati penguva yekuoma uye nguva yemafashamo. Pasinei neizvi, mhuka nhatu chete dze3 dzakanyoreswa dzakangowanikwa makiromita anopfuura zana kubva panzvimbo yadzakapedzisira kuonekwa.
Kuchengetedza
Takanga tatotaura kuti rudzi urwu rwepink dolphin rwakawedzerwa kune runyoro rutsvuku rwemarudzi akatyisidzirwa. Iri runyoro rutsvuku runoitwa neIUCN, umo marudzi akasiyana-siyana anowedzerwa umo vanopa chimiro cheDD, kureva, data isina kukwana. Nekudaro, iyo pink dolphin isati yaiswa pane dzvuku runyoro, yakambonyorwa se "Vulnerable". Asi nekuda kwechimiro chepink dolphin mhando uye nezve ruzivo rushoma parudzi urwu, maererano nekutyisidzira, ecology uye maitiro ehuwandu.
Kana dziri nzvimbo dzakadzidzwa ma dolphin, zvinoita sekunge dzakatambanudzwa uye dzakatowanda. Zvisinei, nzvimbo idzi dzichangomiririra chikamu chiduku chekugoverwa kwakakwana kwezvienzaniso. Munzvimbo idzi mhando iyi inonyanya kuchengetedzwa. Pasinei neizvi, ruzivo runogona kuwanikwa kubva munzvimbo idzi runogona kunge rusina mumiriri uye runogona kunge rusina basa mune ramangwana.
Asi nekuda kwekusvibiswa uye kuparadzwa kunonoka kweiyo inzvimbo yavo yekugara. Mune mamwe mazwi, sango reAmazon uye kunyangwe kusagadzikana kwezvipenyu. Ndosaka matanho akatevedzana akatorwa kuti adzidzivirire munyika dzose dzinogara mhuka dzacho. Zvinhu zvinopesvedzera tyisidziro yaro kutemwa kwemasango uye iyo miitiro yavanhu iyo ichava nepesvedzero yakaipa. Nokudaro kuchinja nharaunda yavo. Imwe yemanyuko makuru ekuitira hanya kuchava kuoma mukuchengeta marudzi akatapwa ari mapenyu.
Izvi zvinokonzerwa ne intraspecific hutsinye uye hupenyu hurefu hwemhando panguva yekutapwa kwayo inosanganiswawo. Ichi ndicho chikonzero kana nhamba dzepink dolphin dzikatanga kudzikira kusvika kune njodzi zvakanyanya munzvimbo yadzo yechisikigo, panogona kuve nenjodzi yakanyanya yekutsakatika nekuda kwekuoma kwazvakaita kuvachengeta muhusungwa kwenguva yakareba. Iri muna 2008, iyo International Whaling Commission (IWC) yakazivisa uye yakasimudza kunetseka kwayo nezvekuvhimwa kwepink dolphin. Iko kunoshandiswa sechirauro muCentral Amazon.
Izvi ndizvo zvinobudisa dambudziko guru rinobuda rakapararira pamwero mukuru. Mhando yepink dolphin yakabatanidzwa kuAppendix II yeConvention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Mhuka iyi yakaverengerwawo muChitsauko II cheChibvumirano cheKuchengetedzwa kweMhuka dzinotama dzeMhuka.
Maererano netsvagiridzo yakaitwa neSainzi Komiti yeInternational Whaling Commission muna 2000, huwandu hwehuwandu hwepink dolphin hwakakura zvakanyanya. Vanotaurawo kuti pane ruzivo rushoma uye humbowo pakudzikira kwehuwandu hwevanhu uye zvakare nzvimbo yekugovera. Asi zvisinei neizvi, vanoonawo dambudziko riripo pamusoro pekupindira kwevanhu munzvimbo yakasikwa yerudzi urwu. Ndosaka vachiona kuti munguva pfupi iri kutevera ichi chichava chikonzero chingangoitika maererano nekuderera kweramangwana muhuwandu hwayo.

Zvinotyisa
Iyo pink dolphin, sezvatsanangurwa pamusoro apa, iri parunyoro rutsvuku rwemhuka dziri mungozi. Ichi ndicho chikonzero mhuka iyi yakachengetedzwa uye ichiremekedzwa. Nekudaro, kuvhima, kuteya, kubata hove netsaona uye kunyangwe kuparadzwa kwenzvimbo yavo yekugara kwave kuchiwedzera. Zvese izvi zvinhu zvichabatsira mukudzikira kwehuwandu hwepink dolphin. Ichi ndicho chikonzero masangano akawanda ari kuronga matanho ekurwisa matambudziko aya anoita kuti mhuka iyi iparare. Zvadaro, tichazotaura pamusoro pezvinhu zvinokonzera kutyisidzira.
Kuvhima uye kuuraya nemaune
Sezvambotaurwa, mhuka iyi yakachengetedzwa uye kunyange kuremekedzwa, asi zvinosuruvarisa nhasi maitiro aya akarasika. Kubva nokuda kwezviito zvakawanda zvoudyire pachikamu chemunhu rudzi urwu rwakakanganiswa. Mamwe ematambudziko aya zvinyorwa zvekushandiswa kwemafuta ayo, mvura iyi inoshandiswa sechiedza. Kana kuri kuvhima, maIndia eMuran aitarisira kuavhima pedyo neManaus, Brazil. Mhuka iyi inovhimwawo sezvinhu zvekuyedza kugadzira mushonga uye kutoda mazango. Pakati pezvimwe zvikonzero nei vachivhimwa zvisina kufanira noudyire hwevanhu.
Accident Catch
Kushandiswa kwemambure ekuredza naironi kwakawedzera kubatwa kwepink dolphin. Iyi nzira, iyo yakashandiswa kubva muna 1990, yakapararira nechinangwa chekutora "piracatinga" (Calophysus macropterus). Kutora izvi kune njodzi yakaipisisa kumarudzi. Imwe tyisidziro inokanganisawo pink dolphin ine chekuita nekuvakwa kwezvidyarwa zvehydroelectric mumitsetse mikuru yeAmazon. Izvi zvinokonzera kuderera kwemarudzi ehove, ndicho chikonzero pasina chikafu chakakwana chemhando ye dolphin.
Chimwe chinhu chakakosha mukutyisidzirwa kwerudzi urwu kuvakwa kwemadhamu ayo achaparadzanisa vanhu vakasiyana. Kukonzera kuti kuve nekuderera kwekuchinjana kwemajini, zvichikonzera kuwedzera kwekugona kwekutsakatika kwenzvimbo. Sezvineiwo, izvi zvinoita kuti mapink dolphin asaberekane nekudaro hapazove nemwana mutsva anoenderera mberi nedzinza ravo.

Sezvatsanangurwa pamusoro apa, kuwedzera kwemambure ekuredza naironi muAmerica yose kwakanganisa marudzi aya. Dzvinyiriro inounzwa nokuredza inoumbawo rudzi rwemakwikwi akasimba zvikuru pakati pemadolphin nevabati vehove vamene nokuda kwehove. Zvinoenderana nezvidzidzo zvakaitwa papink dolphin, zvakaonekwa kuti kudya kwavo kunobva pa43% chete yemhando makumi mashanu nenhatu dzehove dzinotengeswa nemubati wehove. Saka hove dzinobatwa hadzisi kuzova dzakakura zvakakwana kuti pave nechido chekutengeserana.
Habitat Degradation
Kushatiswa uye kusvibiswa kwepink dolphin pekugara ndechimwe chezvinhu zvikuru zvinopesvedzera kutyisidzira kwerudzi urwu. Chimwe chezvinhu zvinokonzeresa kuparara kwenzvimbo yepink dolphin kuwana huni kubva mukuparadzwa kwemasango muAmazon inonaya mvura. Iyi ndiyo imwe yemigumisiro inobva mukuvapo kwevanhu uye nezviito zvavo zveudyire. Zviito zvimwe chete izvi ndizvo zvinozoita kuti varasikirwe nekugara kwavo.
Munhu anga achikura nekukurumidza munzvimbo yese yekugovera uye nzvimbo yepink dolphin. Kupfuura zvese, munzvimbo dzeColombia neBrazil. Kuvapo kwevanhu kunounza kuwedzera kwebasa rekurima pamwe chete nekutema masango, zvipfuyo uye kunyange minda. Panyaya yekuparadzwa kwemasango emvura kuti aenderere mberi nemabasa ekurima uye kunyangwe indasitiri yematanda. Izvi zvinotungamira kumatambudziko anokanganisa hydrological cycle uye riparian ecosystem.
Imwe yemigumisiro mikuru inokonzerwa nekuparadzwa kwemasango ndiko kuderera kwekuwanda kwehove. Izvi zvinokonzeresa kuwanda kwechikafu kuma dolphin nezvimwe zvikara kuve kushoma uye kudzikisirwa. Chimwe chinogona kukonzera kuchinjwa kwekugara kwerudzi urwu kuvakwa kwezvirimwa zvemagetsi emvura. Aya mavakirwo achange ari chipingamupinyi chikuru chekutama kwemarudzi uye kunyange mhuka dzayo. Izvi zvinoburitsa muganho wekuwana chikafu uye zvinofarira kuparadzaniswa kana kupatsanurwa kwevanhu vakasiyana.
Zvikara
Parizvino hapana chinyorwa chezvikara zvakarongeka zvepink river dolphin. Asi zvinonzi black caiman ( Melanosuchus niger ), bull shark ( Carcharhinus leucas ), anaconda ( Eunectes murinus ) uye jaguar ( Panthera onca ) zvinogona kuva nengozi zvikuru nokuda kwepingi dolphin. Sezvo izvi zvinogona kutora nyore mhuka iyi. Dzimwe mhuka dzakaonekwa dziine mavanga akaita secrescent akabatana necatfish yemhuri yeCetopsidae neTrichomycteridae.
Kana wanga uchifarira nyaya iyi yePink Dolphin, ini ndinokukokawo kuti uenderere mberi nekuverenga zvinyorwa zvinotevera:
