Hozhwa dzinomhanya kupfuura zvingafungwa nemunhu, zviri nyore kuvhara mita paawa. Ndizvo zvakaonekwa nevatsvakurudzi vepaYunivhesiti yeExeter pavakaronda hozhwa dzemugadheni mazana mana nemakumi mashanu vachishandisa maLED nependi yeUV. Saizvozvo, ma mollusks anodawo kushandisa rudzi rwe slime trail slipstream. Nyaya yekuti hozhwa dzinofamba nekukasika ine zvayaikanganisa: the lungworm Angiostrongylus vasorum, a utachiona hunotyisidzira upenyu hwembwa, anofamba navo. MuGreat Britain, nekuda kwemakore akapfuma muhozhwa, yakatopararira kubva kumusha wemadzitateguru ayo kumaodzanyemba kusvika kuScotland.
Hozhwa panzira
Chikwata chinotungamirwa nenyanzvi yezve ecologist Dave Hodgeson kekutanga vakanyora nemazvo zviitiko zvehusiku zvehozhwa vachishandisa marambi e LED anonamirwa kumusana kwemhuka uye kurekodha kwenguva. Vakashandisawo mavara eUV kuita kuti makwara ezvinokambaira aonekwe. "Zvigumisiro zvinoratidza hozhwa dzinofamba kusvika mamita makumi maviri nemashanu mumaawa makumi maviri nemana," akadaro Hodgeson. Kuedza kwemaawa 25 kwakajekesawo kuti mhuka idzi dzinoongorora sei zvakadzipoteredza, kwadzinopotera, uye kuti dzinofamba sei.
“Takaona kuti hozhwa dzinofamba dzakatevedzana, dzakaita sedzakadududza pamatope edzimwe hozhwa,” inodaro nyanzvi yezvipenyu. Chikonzero cheizvi chiri nyore. Saka kana mollusk ichitevera nzira iripo, yakaita senge kutsvedza, Hodgeson anotorwa neBBC achiti. Izvi zvinodaro nekuti hozhwa inochengetedza simba, uye zvakanyanya kudaro. Maererano nefungidziro, 30 kusvika 40 muzana yesimba rezvinokambaira rinodiwa nekuda kwekugadzirwa kwematope.
Zvipembenene zvinotakurwa
Mhedzisiro yacho yakaverengerwa mu "Slime Watch" mushumo nemushandirapamwe weBritish Iva Lungworm Aware. Izvi zvinoda kukwevera pfungwa kuti imbwa parasite Angiostrongylus vasorum inogona kukurumidza sei kupararira nehozhwa. Imbwa dzinogona kuimedza zviri nyore pamwe nediki diki slugs inowanikwa pamatoyi kana mumapuddles, semuenzaniso. Zvipembenene zvinozopinda mumapapu uye, zvichienderana nekuoma kwechirwere, zviratidzo zvinotangira kubva. kukosora, kubuda ropa, kurutsa, uye manyoka kusvika pakutadza kufamba kweropa. Kana pane kufungidzira kuti imbwa ine utachiona hwemapapu, chiremba wemhuka anofanira kubvunzurudzwa pakarepo - ipapo chirwere chinogonawo kurapwa nyore nyore.
Chipembenene, icho chinotanga kuitika kunyanya muFrance, Denmark, neEngland, chakapararira zvakanyanya mumakore achangopfuura, kwete muGreat Britain chete. Dieter Barutzki anobva kuFreiburg Veterinary Laboratory akaburitsa chidzidzo muna 2010, maererano nerudzi urwu rwegonye remapapu rave kupararira, kunyanya kumaodzanyemba kwakadziva kumadokero kweGermany. Munyika ino, zvakare, hozhwa ihozhwa yakakosha yepakati uye nokudaro inoisa njodzi yekutapukirwa kushamwari yepedyo yemunhu.
