Increased tolerance to humans among disturbed wildlife

Area of Science:

• Ecology
• Conservation Biology
• Wildlife Management

Background:

• Human activities significantly impact species populations, leading to declines.
• Some species exhibit remarkable adaptability and thrive in human-dominated environments.
• Species tolerance to human disturbance is a key factor in understanding coexistence.

Purpose of the Study:

• To conduct a comprehensive meta-analysis on the tolerance of birds, mammals, and lizards to human disturbance.
• To identify the primary drivers influencing the tolerance of bird species to human disturbance.
• To inform conservation strategies for managing wildlife in increasingly disturbed landscapes.

Main Methods:

• A meta-analysis was performed on existing data for birds, mammals, and lizards.
• Statistical analyses were used to assess species tolerance across different disturbance levels.
• Predictive models were developed to explore factors affecting bird tolerance.

Main Results:

• Populations in disturbed areas demonstrated higher tolerance to human disturbance across all three taxa.
• For birds, the type of disturbed area was a significant predictor, with urbanized populations showing greater tolerance.
• Body mass was another key factor, with larger bird species being more tolerant than smaller ones.

Conclusions:

• Species tolerance to human disturbance varies and is influenced by environmental context and species traits.
• Understanding these tolerance mechanisms is crucial for predicting species responses to urbanization and habitat alteration.
• The findings provide a basis for evidence-based conservation planning to mitigate human impacts and promote wildlife coexistence.
