Effects of the human footprint
Over the Earth’s terrestrial surface, wildlife species are adversely affected by an increasing number of anthropogenic impacts to the landscape, collectively termed the “human footprint”. We conducted a synthesis of cause-specific mortality of North American terrestrial mammals, examining how traits such as human footprint of the study area, species lifespan, and diet interacted to influence anthropogenic mortality of mammals. We found that anthropogenic mortality of mammals increased with increasing human-associated impacts on the landscape, and that longer-lived species were affected more than their shorter-lived counterparts. These shifts in mortality can have substantial implications for understanding wildlife population dynamics and managing these populations across landscapes impacted by anthropogenic activities.
