Population decline proposed occur due changes in forage availability, insect harassment, parasite load, habitat while possible role infectious diseases has not been emphasized. goal present article describe an outbreak fatal pasteurellosis that occurred introduced population Dovrefjell, Norway 2006, causing death a large proportion animals. epizootic coincided with extraordinary warm humid weather, conditions often are associated outbreaks pasteurellosis. description based on long series data from surveillance population, weather closely located meteorological station, pathoanatomical investigation diseased It concluded likely were decisive factors for outbreak. suggested such epizootics may increasingly among cold-adapted animals if global warming results increased occurrence heat waves events, thereby declines possibly extinctions.
