COVID-19 Pandemic Lockdowns Altered Mammal Movement Behaviors Worldwide

A recent research study found that COVID-19 lockdowns dramatically affected mammalian movement habits. In rigorous lockdown locations, animals took a trip 73% farther and moved 36% closer to roadways, suggesting a decrease in worry of human existence or traffic. These findings underscore the effect of human activity on wildlife and offer insights for future conservation efforts.
A new research study indicates that the minimized traffic and human mobility throughout the 2020 COVID-19 lockdown constraints quickly altered some mammals movement habits. When those activities stop, the findings highlight how human activities restrict animal motion and how animals react. These insights could show useful in future preservation strategies targeted at improving human-wildlife coexistence.
The Anthropause and Its Impact on Wildlife
During the early international outbreak of COVID-19 in 2020, governments introduced lockdown steps to suppress the infections spread. This resulted in a remarkable reduction in human mobility and car traffic. The taking place period, known as the “anthropause,” offered a distinct opportunity to measure the effects of human activity on wildlife habits. Roads impact conservation efforts for numerous types due to reduced habitat, limiting population dispersal, and automobile accidents triggering animal mortality. The understanding of roads impact on animal behavior throughout species and on an international scale is limited.
The Research Methodology and Dataset
Marlee Tucker and colleagues utilized the natural experiment offered by COVID-19 lockdowns to assemble GPS tracking data from 76 studies. This dataset included about 2,300 specific mammals, representing 43 species worldwide. They analyzed how these animals altered their habits throughout the preliminary 2020 lockdown period (February 1– April 28, 2020) compared with the same duration in 2019.

In stringent lockdown locations, animals took a trip 73% farther and moved 36% closer to roadways, suggesting a decline in fear of human presence or traffic. The findings highlight how human activities limit animal movement and how animals respond when those activities stop. They examined how these animals altered their habits during the preliminary 2020 lockdown duration (February 1– April 28, 2020) compared with the very same period in 2019.

In areas where COVID-19 lockdown policies were more stringent, animals traveled on typical 73% farther throughout the lockdown period than the previous year.

Findings from the Study
Despite variations in specific motion and road avoidance habits reactions to lockdowns across areas and types, Tucker and her team exposed numerous consistent impacts. In areas where COVID-19 lockdown policies were stricter, animals traveled usually 73% further throughout the lockdown duration than the previous year. This recommends that animals in these locations explored more of the landscape when automobile movement was lessened. Additionally, the research study found that short-distance mammal motions in inhabited human areas decreased, and people took a trip 36% closer to streets throughout lockdowns. This is possibly due to the fact that animals were less afraid of road traffic or human presence in these locations and exhibited shorter fleeing ranges as a result.
Commentary on the Study
In an associated Perspective, Colleen Cassady St. Clair and Sage Raymond composed, “Tucker et al. offered a comprehensive answer about some animals ability to use human-inhabited areas and broaden their habitats when human activity declines. Their outcomes highlight the ecological impact of lorry activity, which is often gone over less publicly than the effects of emissions, long-term roadway infrastructure, and environment loss.”
