West Coast, Best Coast? Kwete zveStarfish.

Chirwere chisinganzwisisike chiri kutsvaira West Coast, ichisiya musarasara wehove dzakafa.

Kubva munaChikumi 2013, mirwi yenyeredzi dzemugungwa dzakafa dzine mitezo yakavharika inogona kuonekwa pamwe neWest Coast, kubva kuAlaska kuenda kuSouthern California. Nyeredzi dzemugungwa idzi, dzinonziwo starfish, dziri kufa nemamiriyoni uye hapana anoziva chikonzero nei.

Nyeredzi yegungwa inoparadza chirwere, zviri pachena kuti chirwere chakanyanya kupararira chati chambonyorwa muzvisikwa zvemugungwa, chinogona kutsvaira nyeredzi dzemugungwa mukati memazuva maviri chete. Nyeredzi dzemugungwa dzinotanga kuratidza zviratidzo zvekubatwa nehosha yekurasa yegungwa nekuita lethargic - maoko avo anotanga kumonereka uye vanoita kuneta. Ipapo maronda anotanga kuonekwa muhapwa uye/kana pakati pemaoko. Maoko estarfish anobva adonha zvachose, inova inowanzoitika kushushikana kwe echinoderms. Nekudaro, mushure mekunge maoko mazhinji adonha, matishu emunhu anotanga kuora uye starfish inobva yafa.

Mamaneja ePaki paOlympic National Park muWashington State ndivo vanhu vekutanga kuwana humbowo hwechirwere ichi muna 2013. Mushure mekuonekwa kwekutanga nemamaneja aya nevashandi vesainzi, vanhu vakasiyana-siyana venhandaro vakatanga kuona zviratidzo zvehosha inoparadza nyeredzi yegungwa. Apo zviratidzo zvakatanga kuitika kakawanda munyeredzi dzegungwa dziri muPacific Northwest, yakanga yava nguva yekufumura chakavanzika chechirwere ichi.

Ian Hewson, mubatsiri purofesa wemicrobiology paCornell University, mumwe wenyanzvi shoma dzakashongedzerwa kuita basa rekuona chirwere chisingazivikanwe ichi. Ndakaita rombo rakanaka rekukwanisa kutaura naHewson, uyo parizvino ari kutsvagurudza nyeredzi yegungwa inoparadza chirwere. Ruzivo rwakasiyana rwaHewson rwekusiyana-siyana kweutachiona uye utachiona hunomuita iye munhu chaiye wekunongedza chirwere ichi chisinganzwisisike chiri kubata marudzi makumi maviri estarfish.

Mushure mekugamuchira rubatsiro rwegore rimwe kubva kuNational Science Foundation muna 2013, Hewson anga achishanda nemasangano gumi neshanu, semasangano edzidzo kuWest Coast, Vancouver Aquarium, neMonterey Bay Aquarium, kuti atange kuferefeta chirwere ichi. Nzvimbo dzemumvura dzakapa Hewson ruzivo rwake rwekutanga: chirwere chakabata akawanda ehove dzenyeredzi muunganidzwa wemvura.

"Zviripachena chimwe chinhu chiri kuuya kubva kunze," akadaro Hewson.

Masangano ari kuWest Coast ane basa rekutora nyeredzi dzemugungwa munzvimbo dzepakati. Iwo masampuli anozotumirwa mhiri kweUnited States kune Hewson's lab, iri paCornell's campus. Basa raHewson nderekutora iwo masampuli uye kuongorora DNA yenyeredzi dzegungwa, mabhakitiriya, uye mavhairasi mazviri.

Parizvino, Hewson akawana humbowo hwekubatana kwehutachiona mune chirwere chenyeredzi yegungwa tishu. Mushure mekuwana tupukanana mumatishu, zvaive zvakaoma kuti Hewson asiyanise izvo tupukanana tunokonzera chirwere.

Hewson anoti, “Chinhu chakaoma ndechekuti, hatina chokwadi kuti chii chiri kukonzera chirwere ichi uye kuti chii chiri kungodya nyeredzi dzemugungwa kana dzaora.”

Kunyangwe hazvo nyeredzi dzemugungwa dziri kufa zvisina mukare akamboona, Hewson akasimbisa kuti chirwere ichi chinokanganisa zvimwe zvipenyu zvakawanda zvakare, senge sosi huru yekudya kwenyeredzi dzemugungwa, hove. Nenhengo dzakakura dzenyeredzi dzemugungwa dziri kufa nehosha yegungwa inoparadza, pachava nekudzikira kwemhashu, zvichiita kuti huwandu hwavo huwedzere. Shellfish inogona kutora pamusoro peecosystem, uye zvichitungamira kuderera kunoshamisa mukusiyana kwezvipenyu.

Kunyangwe chidzidzo chaHewson chisati chaburitswa, akandiudza chinhu chimwe chakakosha: "Zvatakawana zvinotonhorera uye tupukanana. ndivo zvinobatanidzwa.”

Ita shuwa yekutarisa kumashure neiyo Ocean Foundation's blog munguva pfupi iri kutevera kune yekutevera nyaya mushure mekudzidza kwaIan Hewson kwaburitswa!
