Per Atlant\u0105 besidriekiantis vadinamasis Didysis Atlanto Sargassum dir\u017eas pastaraisiais metais tapo vienu ry\u0161kiausi\u0173 j\u016brini\u0173 rei\u0161kini\u0173: tai mil\u017eini\u0161ka pl\u016bduriuojan\u010di\u0173 rud\u0173j\u0173 dumbli\u0173 Sargassum sankaupa, nusit\u0119sianti nuo Vakar\u0173 Afrikos link Karib\u0173 ir Meksikos \u012flankos. Mokslininkai pabr\u0117\u017eia, kad atviroje j\u016broje \u0161ios \u201esalos\u201c yra svarbi buvein\u0117 daugeliui r\u016b\u0161i\u0173, ta\u010diau pakrant\u0117ms jos da\u017enai virsta brangiai kainuojan\u010dia problema.<\/p>\n

Sargassum augimui labiausiai reikia \u0161viesos ir maistini\u0173 med\u017eiag\u0173, ypa\u010d azoto ir fosforo. Ilg\u0105 laik\u0105 buvo svarstoma, i\u0161 kur j\u0173 atsiranda tiek daug: tarp pagrindini\u0173 versij\u0173 min\u0117tos Amazon\u0117s up\u0117s atne\u0161amos med\u017eiagos, Sacharos dulk\u0117s bei vandenyno srovi\u0173 ir vandens masi\u0173 mai\u0161ymasis.<\/p>\n

Reik\u0161mingu veiksniu laikomas ir vadinamasis upwellingas, kai v\u0117sesni, mineralais turtingesni gilesni vandenys pakyla \u012f pavir\u0161i\u0173. Taip \u012f saul\u0117s ap\u0161viest\u0105 zon\u0105 patenka maistin\u0117s med\u017eiagos, kurios gali spartinti fotosintetinan\u010di\u0173 organizm\u0173, \u012fskaitant sargasus, augim\u0105.<\/p>\n

Kas pasikeit\u0117 pastaraisiais metais<\/h2>\n

Naujesni tyrimai i\u0161ry\u0161kino, kad svarbus gali b\u016bti fosforo atitek\u0117jimas i\u0161 pusiaujo zon\u0173 Atlante. \u0160is elementas, tyr\u0117j\u0173 vertinimu, gali netiesiogiai sustiprinti mikroorganizm\u0173, geban\u010di\u0173 \u201epriri\u0161ti\u201c atmosferos azot\u0105, aktyvum\u0105, o tai galiausiai padidina azoto prieinamum\u0105 ir skatina dumbli\u0173 ve\u0161\u0117jim\u0105.<\/p>\n

Dar daugiau d\u0117mesio sulauk\u0117 hipotez\u0117, kad patys sargassum s\u0105\u017ealynai vis geriau \u201eu\u017esuka\u201c maistini\u0173 med\u017eiag\u0173 cikl\u0105 savo viduje. Kitaip tariant, dir\u017e\u0105 gali palaikyti ne tik i\u0161oriniai \u0161altiniai, bet ir vis efektyvesnis med\u017eiag\u0173 perdirbimas ten pat, kur dumbliai auga.<\/p>\n

Gyvyb\u0117s sala ir pakran\u010di\u0173 galvos\u016bkis<\/h2>\n

Pl\u016bduriuojan\u010dios Sargassum sankaupos n\u0117ra vien dumbli\u0173 mas\u0117: jos sudaro sud\u0117ting\u0105 mikroekosistem\u0105, kurioje gyvena \u017euvys, krevet\u0117s, krabai ir daugyb\u0117 smulki\u0173 organizm\u0173. Maitindamiesi jie i\u0161 aplinkos paima med\u017eiagas, o v\u0117liau j\u0173 apykaitos produktai vanden\u012f praturtina maistin\u0117mis med\u017eiagomis, kurios v\u0117l gali b\u016bti panaudotos dumbliams.<\/p>\n

Problemos prasideda tada, kai dideli kiekiai dumbli\u0173 supl\u016bsta \u012f seklumas ar i\u0161metami \u012f papl\u016bdimius. P\u016bvant biomasai gali i\u0161siskirti sieros vandenilis, suprastinantis oro kokyb\u0119, o storas dumbli\u0173 sluoksnis paj\u0117gus kenkti pakran\u010di\u0173 ekosistemoms ir apsunkinti turizmo bei vietos paslaug\u0173 veikl\u0105.<\/p>\n

Pasak mokslinink\u0173, kuo tiksliau bus suprasta, i\u0161 kur Sargassum gauna maistines med\u017eiagas ir kaip jas perdirba, tuo patikimiau bus galima prognozuoti b\u016bsimus suve\u0161\u0117jimus. Tai svarbu ne tik j\u016br\u0173 ekologijai, bet ir pakrant\u0117ms, kurios kasmet susiduria su vis didesniais valymo, logistikos ir visuomen\u0117s sveikatos i\u0161\u0161\u016bkiais.<\/p>\n","protected":false},"excerpt":{"rendered":"
