Ich strat\u00e9gia pre\u017eitia v extr\u00e9mne such\u00fdch oblastiach (ako s\u00fa p\u00fa\u0161te Austr\u00e1lie, Mexika alebo Afriky) je absol\u00fatne d\u00f4myseln\u00e1 a pos\u00fava pojem \u201e\u0161pajza\u201c na \u00faplne nov\u00fa \u00farove\u0148.<\/p>\n\n\n\n
Ako funguje \u017eiv\u00e1 n\u00e1dr\u017e
Ke\u010f je po vz\u00e1cnych da\u017e\u010foch dostatok potravy \u2013 napr\u00edklad sladk\u00e1 medovka z vo\u0161iek alebo \u0161\u0165avy z rastl\u00edn \u2013 robotnice ju za\u010dn\u00fa skladova\u0165. Ke\u010f\u017ee v nor\u00e1ch mravcov nie s\u00fa \u017eiadne sudy ani pl\u00e1sty, ako s\u00fa v\u010dely, niektor\u00ed robotn\u00edci (takzvan\u00ed rept\u00e1ni) sa obetuj\u00fa:<\/p>\n\n\n\n
K\u0155menie: In\u00e9 mravce vyvracaj\u00fa zozbieran\u00fd nekt\u00e1r pred doj\u010datami a neust\u00e1le ich k\u0155mia.
Roz\u0161\u00edrenie: \u00daroda (pred\u017eal\u00fadok) t\u00fdchto vybran\u00fdch mravcov extr\u00e9mne napu\u010diava. Pru\u017en\u00e9 blany ich brucha sa roztiahnu nato\u013eko, \u017ee m\u00f4\u017eu ma\u0165 ve\u013ekos\u0165 mal\u00e9ho hrozna \u2013 pln\u00e9ho jant\u00e1rovo sfarbenej cukrovej \u0161\u0165avy.
T\u00e1bor: \u00daplne zjeden\u00e9 mravce s\u00fa tak\u00e9 \u0165a\u017ek\u00e9, \u017ee sa takmer nem\u00f4\u017eu pohybova\u0165. Dr\u017eia sa stropu kom\u00f4r hlboko vo vn\u00fatri hniezda a visia tam cel\u00e9 mesiace ako \u017eiv\u00e9 lustre.
Distrib\u00facia krmiva v obdob\u00ed sucha
Ke\u010f za\u010d\u00edna obdobie sucha a vonku u\u017e nie je \u017eiadna potrava, prich\u00e1dza hodina \u017eiv\u00fdch rezervo\u00e1rov. Ak spolo\u010dn\u00e1 kol\u00f3nia potrebuje energiu, jemne poklepe svojimi tykadlami po hlave medovn\u00edkov\u00e9ho mravca. To potom regurgituje kvapku v\u00fd\u017eivnej \u0161\u0165avy (proces naz\u00fdvan\u00fd trofalaxia).<\/p>\n\n\n\n
Vedeli ste? Pre domorod\u00fdch obyvate\u013eov Austr\u00e1lie (Aborig\u00e9ncov) boli medovn\u00edkov\u00e9 mravce v\u017edy pova\u017eovan\u00e9 za sladk\u00fa poch\u00fa\u0165ku. Opatrne vyhrab\u00e1vaj\u00fa hlbok\u00e9 komory, aby si ich mravce mohli vychutna\u0165 priamo ako v\u00fd\u017eivn\u00fa ma\u0161krtu.<\/p>\n","protected":false},"excerpt":{"rendered":"
