Flaming\u0173 plunksn\u0173 spalva tiesiogiai susijusi su tuo, k\u0105 jie lesa. \u0160ie pauk\u0161\u010diai minta dumbliais, s\u016brymini\u0173 v\u0117\u017eiagyvi\u0173 artemij\u0173 ir kit\u0173 smulki\u0173 vanden\u0173 organizm\u0173 gausa, o su maistu gauna karotinoid\u0173 \u2013 nat\u016brali\u0173 pigment\u0173, suteikian\u010di\u0173 raudonus, oran\u017einius ir geltonus atspalvius.<\/p>\n
Karotinoidai pauk\u0161\u010dio organizme palaipsniui kaupiami ir per med\u017eiag\u0173 apykait\u0105 \u201eperkeliauja\u201c \u012f plunksnas, tod\u0117l jos i\u0161 pilk\u0161v\u0173 jaunikli\u0173 laikui b\u0117gant ima rausv\u0117ti. Zoologai pabr\u0117\u017eia, kad tai n\u0117ra greitas procesas: ry\u0161kus atspalvis da\u017eniausiai susiformuoja per kelerius metus.<\/p>\n
Flaming\u0173 spalva gali kisti net ir suaugus. Pavyzd\u017eiui, per jaunikli\u0173 maitinimo laikotarp\u012f pauk\u0161\u010diai kartais pa\u0161vies\u0117ja, nes dalis pigment\u0173 ir energijos nukreipiama jaunikli\u0173 auginimui, o ne plunksn\u0173 \u201epalaikymui\u201c.<\/p>\n
Nelaisv\u0117je spalv\u0105 da\u017enai padeda i\u0161laikyti subalansuotas racionas, pritaikytas flamingams. Zoologijos soduose \u012f pa\u0161arus gali b\u016bti \u012fmai\u0161omi karotinoidai, kad plunksnos neprarast\u0173 b\u016bdingo atspalvio, ypa\u010d kai nat\u016bralaus maisto sud\u0117tis skiriasi nuo laukini\u0173 buveini\u0173.<\/p>\n
Vis d\u0117lto id\u0117ja, kad flamingus b\u016bt\u0173 galima paversti m\u0117lynais vien tik pakeitus j\u0173 maist\u0105 ar prid\u0117jus da\u017eikli\u0173, biolog\u0173 vertinama skepti\u0161kai. M\u0117lyna spalva gamtoje da\u017enai atsiranda ne d\u0117l pigment\u0173, o d\u0117l plunksn\u0173 ar odos mikrostrukt\u016br\u0173, kurios \u0161vies\u0105 lau\u017eia ir atspindi taip, kad matome m\u0117lyn\u0105 atspalv\u012f.<\/p>\n
Jei \u012f racion\u0105 b\u016bt\u0173 \u012fmai\u0161yti m\u0117lyni da\u017eikliai, tai nerei\u0161kia, kad jie \u201enus\u0117s\u201c plunksnose kaip karotinoidai. Organizmas tokias med\u017eiagas paprastai suskaido ir pa\u0161alina, tod\u0117l vien tik mityba flamingams nesukurt\u0173 stabilios m\u0117lynos spalvos, koki\u0105 matome pas kai kuriuos kitus pauk\u0161\u010dius.<\/p>\n
Trumpai tariant, flaming\u0173 rausvumas yra mitybos ir biochemijos rezultatas, o m\u0117lynumas da\u017eniausiai reikalaut\u0173 visai kito mechanizmo, susijusio su plunksn\u0173 sandara. D\u0117l to \u201em\u0117lynas flamingas\u201c i\u0161lieka labiau popkult\u016bros fantazija nei reali, moksli\u0161kai pagr\u012fsta galimyb\u0117.<\/p>\n","protected":false},"excerpt":{"rendered":"
