Intensive human land uses negatively affect vertebrate functional diversity.

Area of Science:

• Ecology
• Conservation Biology
• Biodiversity Research

Background:

• Land-use change is the primary driver of global biodiversity loss.
• Understanding impacts on ecological community functional structure is critical.
• Vertebrate functional diversity is essential for ecosystem function.

Discussion:

• Human land uses, particularly intense urban, cropland, and pasture use, decrease functional diversity.
• Amphibians and birds show the strongest negative responses.
• Functional losses occur in both tropical and temperate regions, with tropical areas experiencing greater declines.

Key Insights:

• Land-use change non-randomly alters the functional traits of vertebrate assemblages.
• Functional diversity declines are more pronounced than species loss alone in tropical regions.
• Ecological processes sustained by vertebrates are at risk.

Outlook:

• Urgent conservation strategies are needed to mitigate functional diversity loss.
• Sustainable land management practices are crucial for preserving ecosystem services.
• Further research should focus on the long-term consequences for ecosystem resilience.
