Nhunzi dzerudzi Chaoborus vakabuda semutambi akashamisa padariro re kupisa kwepasi pose, basa raimbofungwa kuti raingoitirwa mhuka dzakadai semombe nevanhu. Kuwanikwa uku, kwakagadzirwa nechikwata chevaongorori vepaUniversity yeGeneva, Switzerland, vachibatsirana neLeibniz Institute for Freshwater Ecology and Inland Fisheries muBerlin (IGB), kwaita kuti paitwezve kuongororwa kuti zvipenyu zvakasiyana-siyana zvinobatsira sei mukubuda kwegasi rinopisa.
Makonye aya anogara mumadziva nemadziva, umo anodya zvakanyanya mosquito makonye sezvavanokura kuti vasvike pakuva vanhu vakuru. Kana vapedza kutenderera kwavo, vanobuda mumvura kuti vabereke, uye vozofa, sezvo vasingadye chikafu kana kuita saizvozvo chete. nekita. Maererano neongororo yakabudiswa muna Sayenzi inoshuma, zvakaratidzwa kuti Chaoborus nhunzi dzinotora mukana wemethane gasi vari mumatope kuti vazadze magasi avo, zvichiwedzera kukanganisa dambudziko remamiriro ekunze.
Masikati, makonye anohwanda mumatope ari pasi pedhamu kuti azvidzivirire pazvikara. Zvisinei, kana hwava usiku, dzinozadza dundira dzadzo nemhepo kuti dzikwire kumusoro dzichitsvaka zvokudya. Iyi nzira inoita seyakapusa, asi pane humwe hudzamu, iyo kumanikidzwa kwemvura inodzivirira mavhesi aya kuti asafure nemhepo. Nekuda kweizvozvo, magonye anosarudza kutora methane yakachengetwa muvhu, achiishandisa se "kuyangarara" kufambisa kukwira kwavo. Izvi zvinoenderana nenzira iyo kupisa kunokanganisa mhuka munzvimbo yayo yakasikwa.
Iyi nzira haisi kuvabvumira chete chengetedza kusvika ku80% yesimba iyo yavaizoshandisa pakushambira, asi inewo zvakakosha zvakatipoteredza. Nekushandisa methane kuzvifambisa, makonye anoinyungudutsa mumvura, izvo zvinowedzera mikana yekuti gasi iri risvike mumhepo, nokudaro zvichibatsira kupisa kwepasi pose. Muchiitiko ichi, zvakakosha kufunga kuti sei Dambudziko remamiriro ekunze rinogona kukanganisa kushandiswa kwesimba.
Maererano nekutsvakurudza, mvura yakachena inonzi inokonzerwa 20% yemethane emissions pamwero wepasi rose. Ichi ichokwadi chinotyisa, tichifunga kuti methane igasi rinotora kusvika 28 times kupisa kupfuura carbon dioxide. Mumadziva, the density yeChaoborus larvae Inosiyana pakati pe2.000 ne130.000 vanhu paskweya mita, zvichienderana nemhando yemvura, ichiwanda mumvura yemhando yakaderera ine chepamusoro chekudya. Ichi chiitiko chinogona zvakare kuenderana ne kuwedzera kweumhutu munzvimbo dzinodziya.
Kudzikamisa kuwanda kwemakonye aya uye, nekudaro, kuburitswa kwemethane, masayendisiti anoratidza kudzora kwakasimba kwemvura yedhamu uye matsime anokonzera chiitiko ichi. Neiyi nzira, kuburitswa kwemethane kunogona kudzikiswa uye hutano hwemadziva ecosystem hunovandudzwa. Chidzidzo ichi chinoburitsa kuti, kunyangwe zvichinakidza, kuvapo kwemakonye aya inhau dzakaipa kune hutano hwenharaunda. Izvi zvinosimbisa kukosha kwekufanira manejimendi iyo inoenderana nemamiriro ekunze.
Mukuwedzera, nyanzvi Daniel McGinnis, mumwe wevanyori vekutsvakurudza, anosimbisa kukosha kwe kunatsiridza kunaka kwemvura. Kugadziriswa kwemvura yetsvina kwakakodzera uye kutonga kwekurima kwakakosha kudzoreredza mamiriro ezvinhu, sezvo makonye aya asingangokanganisa methane chete asiwo anotakura zvinosvibisa pamusoro muzvikamu zvepasi.
- ari Chaoborus larvae inobatsira zvakanyanya kune zvinobudiswa methane.
- Iyi nzira inoitika kuburikidza nekutorwa kwemethane kubva mumatope kuti ayangamire.
- El methane ine greenhouse effect yakakura zvakapetwa ka28 pane izvozvo kabhoni diamoni.
- Hutano hwezvipenyu hwedhamu hunotsamira pane a kutonga kwakakwana kwehutano hwemvura.
Chaoborus nhunzi dzinoita basa risingatarisirwi mukudziya kwepasi, zvichiratidza kukosha kwe utungamiriri hwezvakatipoteredza hunobudirira uye inogoneka kuchengetedza zvipenyu zvedu zvemumvura uye kudzikisira kukanganisa kwemamiriro ekunze. Mamiriro ezvinhu aya anoratidza kuti zvipenyu zvemumvura zvinofanirwa kudzidzwa sei kuti zvinzwisise zvinokonzerwa nemhuka nemaruva eEurope.
Izvo zvakakosha kuti vese vaongorori nevagadziri vezvemamiriro ekunze vatarise pane chitsva ichi chiwanikwa chekugadzira nzira dzisingangogadzirise dambudziko remamiriro ekunze chete asiwo dzinosimudzira yakadzikama yemvura yakachena ecosystem.
