Historie a \u00fapadek<\/h2>\n\n

Rosom\u00e1k, kter\u00fd byl ve Washingtonu t\u00e9m\u011b\u0159 vyhuben kv\u016fli lovu do past\u00ed, otrav\u011b a pron\u00e1sledov\u00e1n\u00ed, se v Kask\u00e1dov\u00e9m poho\u0159\u00ed pozoruhodn\u011b vr\u00e1til.

Nastaven\u00edm fotopast\u00ed a vybaven\u00edm rosom\u00e1k\u016f satelitn\u00edmi obojky z\u00edskali v\u011bdci cenn\u00e9 poznatky o jejich pohybech, vyu\u017e\u00edv\u00e1n\u00ed prost\u0159ed\u00ed a rozmno\u017eovac\u00edm chov\u00e1n\u00ed.<\/p>\n\n

Prost\u0159ed\u00ed a chov\u00e1n\u00ed<\/h2>\n\n

Rosom\u00e1ci jsou vysoce p\u0159izp\u016fsobeni chladn\u00e9mu, zasn\u011b\u017een\u00e9mu prost\u0159ed\u00ed a preferuj\u00ed oblasti s dlouhodobou sn\u011bhovou pokr\u00fdvkou.

Hrozby a ochrana<\/h2>\n\n

Navzdory sv\u00e9 obnov\u011b \u010del\u00ed rosom\u00e1ci st\u00e1le v\u00fdzv\u00e1m. Zm\u011bna klimatu a ztr\u00e1ta p\u0159irozen\u00e9ho prost\u0159ed\u00ed mohou ovlivnit jejich schopnost nach\u00e1zet potravu a m\u00edsta pro doupata.
