Anthu amakhulupirira kuti kuyeretsa ndi mwayi wamphaka (woweta komanso wamtchire). Pakadali pano, kuwonjezera pa amphaka, zimbalangondo, akalulu, ma tapir, ma gorilla, afisi, nkhumba, zigoli, ma raccoon, agologolo, mandimu komanso njovu zimatulutsa phokoso lowoneka bwino. Ndipo - chifukwa chiyani amphaka amayeretsa?
Chinsinsi cha purring kapena komwe kumveka kumveka
Akatswiri a zoo akhala akufufuza komwe gwero laphokoso la chiberekero limachokera, ndikuwonetsa kuti pali chiwalo chapadera choyang'anira kutsuka. Koma, atayeserera zingapo, adatsimikiza zakusagwirizana kwa chiphunzitsochi ndikutulutsa china.
Chizindikiro cha minofu chomwe chimapanga kulumikizana kwa zingwe chimachokera mwachindunji ku ubongo. Ndipo chida chomwe chimapangitsa kugwedezeka kwamphamvu kwa zingwe zamawu ndi mafupa a hyoid omwe ali pakati pazoyambira za lilime ndi chigaza.
Ataona zilombo za mchira mu labotale, akatswiri a sayansi ya zamoyo adazindikira kuti amphaka amatsuka, pogwiritsa ntchito mphuno ndi pakamwa, ndikunjenjemera kumafalikira mthupi lonse. Chodabwitsa, simungamvetsere mtima wamphaka ndi mapapu ake uku akung'ung'udza.
Manambala ochepa
Pozindikira mtundu wa purring, akatswiri asayansi samangodzipangira okha kufunafuna komwe kumveke mawu, koma adaganiza zophunzira mozama magawo ake.
Mu 2010, kafukufuku adasindikizidwa ndi Gustav Peters, Robert Ecklund ndi Elizabeth Duthie, omwe akuyimira University of Lund (Sweden): olembawo adayeza kuchuluka kwa phokoso lodabwitsa mosiyanasiyana. Zidachitika kuti purrisi ya paka imapezeka mu 21.98 Hz - 23.24 Hz. Kugunda kwa cheetah kumadziwika ndi mitundu ina (18.32 Hz - 20.87 Hz).
Chaka chotsatira, ntchito yothandizana ndi a Robert Ecklund ndi Suzanne Scholz idasindikizidwa, yomwe idatchulapo amphaka anayi omwe adatsuka kuyambira 20.94 Hz mpaka 27.21 Hz.
Ofufuzawo adatsindikanso kuti kuyeretsa kwa amphaka amtchire komanso oweta kumasiyana mosiyanasiyana, matalikidwe ndi magawo ena, koma ma frequency band sanasinthe - kuyambira 20 mpaka 30 Hz.
Ndizosangalatsa! Mu 2013, Gustav Peters ndi Robert Ecklund adawonanso ma cheetah atatu (mwana wamphaka, wachinyamata, komanso wamkulu) kuti awone ngati phokoso limasintha pafupipafupi ndi zaka. Munkhani yomwe idasindikizidwa, asayansi adayankha funso lawo motsutsana.
Zifukwa zoperekera mphaka
Amatha kukhala osiyana kwambiri, koma samalumikizidwa ndi nkhanza: kubangula kwa amphaka awiri a Marichi sikungatchedwe purr.
Nthawi zambiri zifukwa zomwe amphaka amadzipangira amakhala prosaic ndipo amakhala ndi tanthauzo lamtendere.
Nyama yaubweya imafuna purr kuti ikumbutse mwini wake gawo lotsatira la chakudya kapena kusowa kwa madzi m'kapu. Koma nthawi zambiri, amphaka amang'ung'udza akamasisitidwa. Zowona, potengera kupindika kwa mchira, nthawi yomwe mutha kuwonetsa chikondi iyenera kusankhidwa mosamala.
Malinga ndi akatswiri a zoogera, kuyeretsa sikumangokhala kotopetsa - nthawi zonse kumalumikizidwa ndi mtundu wina wa kutengeka, kuphatikiza kuthokoza, chisangalalo, mtendere wamaganizidwe, nkhawa kapena chisangalalo mukakumana ndi mwininyumbayo.
Nthawi zambiri kudandaula kumachitika mukamakonzekera kugona: umu ndi momwe chiweto chimafikira msanga momwe amafunira ndikupuma.
Amphaka ena amatulutsa pobereka, ndipo tiana ta makanda timatuluka patatha masiku awiri kuchokera pamene abadwa.
Kuchetsa kwa machiritso
Amakhulupirira kuti fining amagwiritsa ntchito purring kuti achire matenda kapena kupsinjika: kunjenjemera komwe kumatuluka mthupi kumapangitsa kuti magazi aziyenda bwino ndikuyambitsa njira zamagetsi.
Pansi pa purr, chinyama sichimangokhala chete, komanso chimatenthetsa ngati kwazizira.
Ati kuyeretsa kumapangitsa ubongo kutulutsa timadzi timene timagwira ngati mankhwala opha ululu komanso opumitsa minofu. Lingaliro limeneli limatsimikiziridwa ndi mfundo yakuti kuyeretsa nthawi zambiri kumamveka kuchokera kwa amphaka ovulala komanso amphaka opweteka kwambiri.
Malinga ndi akatswiri a sayansi ya zamoyo ku Yunivesite ya California, kunjenjemera kochokera ku purring kumalimbitsa mafupa am'mimba, omwe ali ndi vuto lakusunthika kwawo kwanthawi yayitali: si chinsinsi kuti nyama zitha kukhala zopanda ntchito kwa maola 18 patsiku.
Kutengera malingaliro awo, asayansiwo adalangiza asing'anga omwe akugwira ntchito ndi akatswiri azakuthambo kuti atenge 25 hertz purr. Amakhulupirira kuti mamvekedwewa adzaimika msanga ntchito zaminyewa za anthu omwe akhala ali ndi mphamvu yokoka kwanthawi yayitali.
Eni ake a mafakitale opanga ubweya wopanga 24/7 purring (wokhala ndi tulo tofa nato ndi chakudya) akhala otsimikiza kale kuti amphaka awo ali ndi mphamvu zochiritsa.
Kutulutsa kwa mphaka kumateteza ku nkhawa ndi nkhawa, kumachepetsa mutu waching'alang'ala, kumateteza kuthamanga kwa magazi, kumatonthoza kugunda kwamtima, kumathandizira ndi matenda ena.
Ngakhale mutakhala athanzi labwino, tsiku lililonse mumayesetsa kuweta mphaka ndikumva kung'ung'udza kofewa komwe kumachokera mumtima mwake.
