Gibbon yaimvi (Hylobates muelleri) ndi ya dongosolo la anyani.
Kufalitsa kwa gibbon imvi.
Gibbon imvi imagawidwa pachilumba cha Borneo kupatula dera lakumwera chakumadzulo.
Malo okhala gibbon yaimvi.
Ma giboni akuda amakhala m'nkhalango zobiriwira zobiriwira nthawi zonse komanso nkhalango zobiriwira nthawi zonse, malo odula mitengo ndi nkhalango zachiwiri. Ma Gibbons amakhala osasintha komanso okhazikika. Amakwera m'nkhalango mpaka kutalika kwa mita 1500 kapena mpaka 1700 mita ku Sabah, kuchuluka kwa malo okhala kumatsika kumalo okwera. Kafukufuku wokhudzana ndi kudula mitengo pakugawana magiboni aimvi akuwonetsa kuchepa kwa manambala.
Zizindikiro zakunja za giboni imvi.
Mtundu wa gibbon waimvi umayambira imvi mpaka bulauni. Kutalika konse kwa thupi kumakhala masentimita 44.0 mpaka 63.5. Gibbon imvi imakhala yolemera 4 mpaka 8 kg. Ili ndi mano ataliatali, ofanana ndipo alibe mchira. Gawo loyambira la chala chachikulu limayambira pa dzanja osati pachikhatho, kukulitsa mayendedwe osiyanasiyana.
Ma dimorphism ogonana sanafotokozedwe, amuna ndi akazi ndi ofanana pamakhalidwe.
Kuberekanso kwa gibbon imvi.
Magiboni amvi ndi nyama zogonana ndi amuna okhaokha. Amapanga awiriawiri komanso amateteza mabanja awo. Monogamy amapezeka mwa 3% yokha ya nyama zoyamwitsa. Kukula kwaukwati wamamuna m'minyama ndi chifukwa cha zinthu zachilengedwe monga zakudya zambiri komanso kukula kwa gawo lomwe akukhalamo. Kuphatikiza apo, wamwamuna samayesetsa kuteteza wamkazi m'modzi ndi ana ake, zomwe zimawonjezera mwayi wopulumuka.
Ana anyaniwa amapezeka azaka 8 mpaka 9. Nthawi zambiri wamwamuna amayamba kukwerana, ngati mkaziyo wavomera chibwenzi chake, ndiye kuti akuwonetsa kukonzeka posamira patsogolo. Ngati pazifukwa zina mkaziyo amakana zonena zamwamuna, ndiye kuti amanyalanyaza kupezeka kwake kapena kusiya malowo.
Mkazi amabereka mwana kwa miyezi 7. Kawirikawiri mwana mmodzi yekha amabadwa.
Ma giboni ambiri amvi amaswana zaka ziwiri kapena zitatu zilizonse. Kusamalira ana kumatha mpaka zaka ziwiri. Ndiye maliboni achichepere, monga lamulo, amakhala ndi makolo awo kufikira atakhwima, ndizovuta kunena kuti ali ndi zaka zingati. Ndizomveka kuganiza kuti ma gibboni a imvi amakhala ndi ubale ndi abale awo, monga mamembala ena amtunduwu.
Maliboni achichepere amathandiza kulera ana aang'ono. Amuna nthawi zambiri amakhala otanganidwa kwambiri poteteza ndi kulera ana awo. Magiboni akuda amakhala zaka 44 ali mu ukapolo, ndipo mwachilengedwe amakhala zaka 25.
Makhalidwe a gibbon yaimvi.
Maliboni akuda si anyani oyenda kwambiri. Amayenda m'mitengo, kutsetsereka panthambi ina. Njirayi imapangitsa kuti pakhale zala zazitali, zotsogola, zomwe zimapanga mikono yotseka panthambi. Maliboni amvi amayenda mwachangu modumpha kwakutali ndi malire. Amatha kuyenda mtunda wamamita atatu akasamukira ku nthambi ina komanso pafupifupi 850 mita patsiku. Ma giboni akuda amatha kuyenda molunjika atakweza mikono pamwamba pamutu pawo poyenda pansi. Koma njira iyi yosunthira siyofanana ndi anyaniwa; apa, anyaniwo samayenda mtunda wautali. M'madzi, ma giboni imvi amadzimva osatetezeka, osambira osauka ndipo amapewa madzi otseguka.
Nyani wamtunduwu amakhala m'magulu a anthu atatu kapena anayi. Palinso amuna amodzi. Awa ndi magiboni omwe adakakamizidwa kusiya mabanja awo ndipo sanakhazikitse gawo lawo.
Ma giboni akuda amagwira ntchito kwa maola 8-10 patsiku. Nyama izi zimasintha, zimadzuka m'mawa ndikubwerera usiku usanalowe.
Amuna amakonda kukhala achangu m'mbuyomu ndipo amakhala atcheru nthawi yayitali kuposa akazi. Maliboni akuda amayenda kukafunafuna chakudya pansi pa denga la nkhalango.
Maliboni akuda ndi nyama zachilengedwe, koma samathera nthawi yochulukirapo polumikizana monga mitundu ina ya anyani. Kudzikongoletsa komanso masewera azisangalalo amatenga zochepera 5% pazochitika za tsiku ndi tsiku. Kuperewera kwa kulumikizana komanso kulumikizana kwambiri kumatha kukhala chifukwa cha ocheperako omwe mumacheza nawo.
Amuna ndi akazi achikulire amagwirizana kwambiri. Zochitika zasonyeza kuti amuna amasewera ndi ma giboni ang'onoang'ono. Zidziwitso zochepa ndizomwe zimapezeka pamitundu yama giboni amvi. Masukulu anyaniwa ndi gawo lawo. Pafupifupi 75 peresenti ya mahekitala 34.2 a malo okhala ndiotetezedwa kuti asalandidwe ndi mitundu ina yachilendo. Kudzitchinjiriza kuderali kumaphatikizaponso kufuula kwammawa m'mawa ndi mafoni omwe amaopseza olowa. Ma giboni akuda nthawi zambiri sagwiritsa ntchito nkhanza poteteza gawo lawo. Zizindikiro zamawu za magiboni amvi zawerengedwa mwatsatanetsatane. Akuluakulu amuna amayimba nyimbo zazitali mpaka mbandakucha. Akazi amafuula dzuwa litatuluka mpaka 10 koloko m'mawa. Nthawi yayitali yamasewerawa ndi mphindi 15 ndipo imachitika tsiku lililonse.
Osungulumwa amuna amayimba nyimbo zambiri kuposa amuna omwe ali ndi peyala, mwina kuti akope akazi. Akazi osakwatira samaimba kawirikawiri.
Monga anyani ena, magiboni amvi amagwiritsa ntchito manja, mawonekedwe a nkhope ndi mawonekedwe polumikizana.
Chakudya cha gibbon imvi.
Zakudya zambiri zamtundu waimvi zimakhala ndi zipatso zakupsa, zipatso za fructose ndi zipatso. Nkhuyu zimakonda kwambiri. Pang'ono ndi pang'ono, anyani amadya masamba achichepere ndi mphukira. M'chilengedwe cha nkhalango yamvula, ma giboni amvi amathandizira pakufalitsa mbewu.
Kufunika kwasayansi kwa gibbon imvi.
Gibbon waimvi ndi wofunikira pakufufuza kwasayansi chifukwa chofanana ndi majini ndi matupi ake kwa anthu.
Mkhalidwe wosungira wa gibbon waimvi.
IUCN imagwiritsa ntchito gibbon yakuda ngati mtundu womwe uli pachiwopsezo chotha. Ulalo wolumikiza m'gulu I umatanthauza kuti mitunduyo ili pachiwopsezo. Gibbon waimvi adatchulidwa kuti ndi mitundu yosawerengeka yomwe imakhudzidwa ndi kudula mitengo mwachisawawa ku Borneo. Mathirakiti akuluakulu m'nkhalango anali atawonongedwa pafupifupi kwathunthu.
Tsogolo la gibbon imvi limadalira kubwezeretsa malo ake achilengedwe, omwe ndi nkhalango za Borneo.
Kudula mitengo mwachisawawa komanso kugulitsa nyama mosaloledwa ndizowopseza kwambiri, ndikuwonjezera kusaka mkati mwa chilumbacho. Kuyambira 2003-2004, anthu 54 a anyani osowa kwambiri adagulitsidwa m'misika ya Kalimantan. Habitat ikutayika chifukwa chakukula kwa minda yamitengo yamafuta ndikukula kwa mitengo. Gibbon wakuda ali mu CITES chowonjezera I. Amakhala m'malo angapo otetezedwa mwachilengedwe m'malo mwake, kuphatikiza mapaki a Betung-Kerihun, Bukit Raya, Kayan Mentarang, Sungai Wayne, Tanjung Puting National Park (Indonesia). Komanso ku Lanjak-Entimau Sanctuary, Semengok Forest Reserve (Malaysia).
