Lemmingov\u00e9 jsou mal\u00ed, hrabaj\u00edc\u00ed hlodavci, kte\u0159\u00ed \u017eij\u00ed v arktick\u00fdch oblastech. Jsou zn\u00e1m\u00ed sv\u00fdmi dramatick\u00fdmi popula\u010dn\u00edmi explozemi, kter\u00e9 vedly k mnoha m\u00fdt\u016fm a omyl\u016fm o jejich chov\u00e1n\u00ed.<\/p>\n\n
Jedn\u00edm z nejtrvalej\u0161\u00edch m\u00fdt\u016f o lemmings je, \u017ee p\u00e1chaj\u00ed hromadnou sebevra\u017edu skokem z \u00fates\u016f. Tento m\u00fdtus je pravd\u011bpodobn\u011b zalo\u017een na dokument\u00e1rn\u00edm filmu spole\u010dnosti Disney z roku 1958 s n\u00e1zvem White Wilderness, kter\u00fd ukazoval des\u00edtky lemming\u016f padaj\u00edc\u00edch z \u00fatesu. Pozd\u011bji se v\u0161ak uk\u00e1zalo, \u017ee tyto z\u00e1b\u011bry byly fale\u0161n\u00e9. Lemmingov\u00e9 byli ve skute\u010dnosti shozeni do mo\u0159e z n\u00e1kladn\u00edho auta.<\/p>\n\n
Ve skute\u010dnosti lemingov\u00e9 sebevra\u017edu nep\u00e1chaj\u00ed. Kdy\u017e se jejich populace stanou p\u0159\u00edli\u0161 hust\u00fdmi, vydaj\u00ed se hromadn\u011b hledat nov\u00e9 \u00fazem\u00ed. Tyto migrace mohou n\u011bkdy v\u00e9st k tomu, \u017ee se velk\u00e9 mno\u017estv\u00ed lemming\u016f utop\u00ed v \u0159ek\u00e1ch nebo spadne z \u00fates\u016f. Toto v\u0161ak nen\u00ed \u00famysln\u00fd akt sebevra\u017edy.<\/p>\n\n
Dal\u0161\u00edm b\u011b\u017en\u00fdm m\u00fdtem o lemming je, \u017ee exploduj\u00ed, kdy\u017e se rozzlob\u00ed. Tento m\u00fdtus je pravd\u011bpodobn\u011b zalo\u017een na skute\u010dnosti, \u017ee lemingov\u00e9 jsou velmi teritori\u00e1ln\u00ed a \u010dasto spolu bojuj\u00ed a\u017e do smrti. Nicm\u00e9n\u011b nevybuchuj\u00ed.<\/p>\n\n
Populace lemming\u016f kol\u00edsaj\u00ed dramaticky, s n\u00e1r\u016fsty a poklesy, kter\u00e9 se vyskytuj\u00ed ka\u017ed\u00e9 dva a\u017e t\u0159i roky. P\u0159\u00ed\u010dina t\u011bchto v\u00fdkyv\u016f nen\u00ed zcela pochopena, ale p\u0159edpokl\u00e1d\u00e1 se, \u017ee souvis\u00ed s faktory, jako je dostupnost potravy, predace a nemoci.<\/p>\n\n
B\u011bhem popula\u010dn\u00ed exploze se lemingov\u00e9 rychle rozmno\u017euj\u00ed a \u0161\u00ed\u0159\u00ed se do nov\u00fdch oblast\u00ed. To m\u016f\u017ee v\u00e9st k p\u0159epln\u011bn\u00ed a sout\u011b\u017ei o zdroje. V d\u016fsledku toho mnoho lemming\u016f zem\u0159e hlady, predac\u00ed nebo nemocemi.<\/p>\n\n
Krom\u011b m\u00fdt\u016f o sebevra\u017ed\u011b a explozi existuje \u0159ada dal\u0161\u00edch myln\u00fdch p\u0159edstav o lemmingu. Nap\u0159\u00edklad n\u011bkte\u0159\u00ed lid\u00e9 v\u011b\u0159\u00ed, \u017ee lemingov\u00e9 v\u017edy migruj\u00ed.
