Ilg\u0105 laik\u0105 manyta, kad j\u016briniai pauk\u0161\u010diai j\u016broje \u012frengtas v\u0117jo j\u0117gaines pirmiausia laiko kli\u016btimi ir, kiek \u012fmanoma, j\u0173 vengia. Dalis r\u016b\u0161i\u0173 i\u0161 ties\u0173 kei\u010dia mar\u0161rutus, kad i\u0161vengt\u0173 susid\u016brimo rizikos, triuk\u0161mo ar trikdymo.<\/p>\n
Ta\u010diau Nyderland\u0173 pakrant\u0117je mokslininkai migracij\u0173 metu pasteb\u0117jo kitok\u012f vaizd\u0105. Retesn\u0117 j\u016brin\u0117 pauk\u0161\u010di\u0173 r\u016b\u0161is prie v\u0117jo j\u0117gaini\u0173 sugr\u012f\u017edavo ne atsitiktinai: jud\u0117jimas tarp konstrukcij\u0173 kartojosi ir atrod\u0117 kryptingas.<\/p>\n
Steb\u0117jimai buvo sutelkti \u012f migruojan\u010dius j\u016brinius pauk\u0161\u010dius, keliaujan\u010dius per \u0160iaur\u0117s j\u016br\u0105, kur nuotolin\u0117se j\u016brin\u0117se teritorijose pastatyta daug v\u0117jo park\u0173. Tokiose kelion\u0117se pauk\u0161\u010diams tenka \u012fveikti didelius atstumus vir\u0161 atviro vandens, kur beveik n\u0117ra viet\u0173 nut\u016bpti ar orientyr\u0173.<\/p>\n
Tyr\u0117jai, analizuodami skryd\u017ei\u0173 trajektorijas ir elgsen\u0105 \u0161alia keli\u0173 v\u0117jo park\u0173, pasteb\u0117jo d\u0117sningum\u0105. Kai kurie individai koregavo krypt\u012f taip, kad priart\u0117t\u0173 prie turbin\u0173, net kai oro s\u0105lygos i\u0161likdavo stabilios.<\/p>\n
Surinkta informacija leido \u012ftarti, kad pauk\u0161\u010diai kai kuriose vietose v\u0117jo j\u0117gaini\u0173 zonas naudoja kaip tarpines stoteles. Priart\u0117j\u0119 prie vienos konstrukcijos, jie trumpam sul\u0117tindavo jud\u0117jim\u0105, o v\u0117liau skrisdavo toliau link kitos.<\/p>\n
Tokie sustojimai da\u017enai b\u016bdavo trumpi, kartais trunkantys vos kelias minutes, bet pasikartojantys. Mokslininkams tai primin\u0117 jud\u0117jim\u0105 tarp dirbtini\u0173 \u201esal\u0173\u201c, i\u0161sid\u0117s\u010diusi\u0173 j\u016broje per vis\u0105 migracijos keli\u0105.<\/p>\n
Pasteb\u0117ta ir tai, kad prie turbin\u0173 pamat\u0173 gali did\u0117ti pauk\u0161\u010di\u0173 maitinimosi aktyvumas. Po vandeniu esantys konstrukcij\u0173 elementai laikui b\u0117gant apauga, susidaro vietos, kur telkiasi smulkesn\u0117 gyv\u016bnija, o paskui ir \u017euvys, pritraukian\u010dios pl\u0117\u0161r\u016bnus, tarp j\u0173 ir pauk\u0161\u010dius.<\/p>\n
Atviroje j\u016broje orientavimasis ypa\u010d sud\u0117tingas, kai matomum\u0105 riboja r\u016bkas, krituliai ar bangavimas. V\u0117jo j\u0117gaini\u0173 eil\u0117s sukuria vertikalius, i\u0161 toli pastebimus objektus, kurie gali pad\u0117ti palaikyti krypt\u012f ir suma\u017einti navigacijos \u201eneapibr\u0117\u017etum\u0105\u201c ilguose perskridimuose.<\/p>\n
Mokslinink\u0173 vertinimu, tokia strukt\u016br\u0173 teikiama nauda gali b\u016bti dvejopa: vizual\u016bs orientyrai ir didesn\u0117 tikimyb\u0117 rasti maisto. Vis d\u0117lto pabr\u0117\u017eiama, kad toks elgesys n\u0117ra universalus ir daugelis kit\u0173 r\u016b\u0161i\u0173 v\u0117jo park\u0173 teritorij\u0173 ir toliau vengia.<\/p>\n
D\u0117l \u0161i\u0173 prie\u017eas\u010di\u0173 tyr\u0117jai ragina v\u0117jo park\u0173 poveik\u012f vertinti ne vien pagal bendr\u0105 \u201evengimo\u201c taisykl\u0119. Skirtingos r\u016b\u0161ys gali reaguoti nevienodai, o kai kurios, pana\u0161u, prisitaiko prie naujos infrastrukt\u016bros grei\u010diau, nei buvo manyta anks\u010diau.<\/p>\n
Ekspertai pa\u017eymi, kad tai nekei\u010dia b\u016btinyb\u0117s planuojant j\u016brinius v\u0117jo parkus vertinti rizikas pauk\u0161\u010diams ir j\u0173 migracijai. Ta\u010diau nauji steb\u0117jimai rodo, jog realus poveikis gali b\u016bti sud\u0117tingesnis: nuo trikdymo ir susid\u016brim\u0173 rizikos iki netik\u0117to \u201enaudojimo\u201c kaip tarpini\u0173 ta\u0161k\u0173 kelion\u0117je.<\/p>\n","protected":false},"excerpt":{"rendered":"
