Bears gradually become nocturnal to avoid contact with people, but many die before adapting successfully, according to study by ecologists from Western Canada.
Learning to live alongside people comes at a high cost for grizzly bears, according to a new study by a team of ecologists from Western Canada.
“These animals are essentially faced with an ‘adapt or die’ scenario,” explained Clayton Lamb, lead author on the study, who conducted the research as part of his PhD with ecologist Stan Boutin and conservation biologist Scott Nielsen.
“The large carnivores we see near towns, most highways or any other highly human-dominated landscape are only able to persist there due to immigration from adjacent wilderness areas,” Lamb noted.
The researchers examined 41 years’ worth of data from more than 2,500 grizzly bears to understand the factors that promote successful coexistence.
“Human-dominated landscapes are risky for grizzly bears. To reduce this risk, many animals are avoiding people...
