Brazilijos \u0161iaur\u0117s rytuose, kur spar\u010diai ple\u010diami v\u0117jo energetikos parkai, mokslininkai fiksuoja netik\u0117t\u0105 poveik\u012f laukinei gamtai: varl\u0117s kei\u010dia poravimosi \u0161auksmus, kad b\u016bt\u0173 i\u0161girstos per nuolatin\u012f j\u0117gaini\u0173 skleid\u017eiam\u0105 \u017eemo da\u017enio \u016b\u017ees\u012f.<\/p>\n

Tyrimuose, atliktuose Caatinga saus\u0173j\u0173 mi\u0161k\u0173 regione, daugiausia d\u0117mesio skirta akustinei tar\u0161ai ir jos \u012ftakai varliagyvi\u0173 komunikacijai, kuri poravimosi metu yra esmin\u0117 r\u016b\u0161ies i\u0161likimui.<\/p>\n

Kas vyksta prie j\u0117gaini\u0173?<\/h2>\n

Tyr\u0117jai \u012fra\u0161in\u0117jo varli\u0173 balsus netoli 107 v\u0117jo turbin\u0173 ir palygino juos su \u012fra\u0161ais i\u0161 tylesni\u0173 vietovi\u0173 greta. Steb\u0117jimai sutelkti \u012f laikinus vandens telkinius, kurie lietinguoju sezonu tampa svarbiausiomis veisimosi vietomis.<\/p>\n

Rezultatai parod\u0117, kad trij\u0173 r\u016b\u0161i\u0173 patinai garsesn\u0117se vietose nuosekliai keit\u0117 \u0161auksm\u0173 ypatybes: vieni koregavo da\u017en\u012f, kiti ma\u017eino impuls\u0173 skai\u010di\u0173 ar j\u0173 stiprum\u0105, dar kiti trumpino \u0161auksmus, bet \u0161aukdavo da\u017eniau.<\/p>\n

Kod\u0117l varl\u0117s kei\u010dia bals\u0105?<\/h2>\n

Mokslinink\u0173 ai\u0161kinimu, tai pana\u0161u \u012f bandym\u0105 i\u0161vengti akustinio maskavimo, kai foninis triuk\u0161mas u\u017ego\u017eia gyv\u016bnams svarbius signalus.

Varl\u0117ms poravimosi \u0161auksmas n\u0117ra \u201etiesiog garsas\u201c: patel\u0117s partner\u012f atpa\u017e\u012fsta pagal laik\u0105, ton\u0105, impuls\u0173 ritm\u0105 ir kartojim\u0105.

Kokios gali b\u016bti pasekm\u0117s gamtai?<\/h2>\n

Nors elgesio prisitaikymas i\u0161 pirmo \u017evilgsnio atrodo kaip s\u0117kminga strategija, tyr\u0117jai pabr\u0117\u017eia galimas biologines \u201es\u0105naudas\u201c. Trumpesni ar pakit\u0119 \u0161auksmai gali ma\u017einti poravimosi s\u0117km\u0119, o ilgainiui tai gali paveikti populiacij\u0173 gaus\u0105.<\/p>\n
