Hypothesis
The evolution of bat pelage markings is associated with roosting ecologies that benefit from crypsis.
Conclusion
The study provides strong support for the idea that roosting ecology has driven the evolution of pelage markings in bats.
Supporting Evidence
- Bats that roost in vegetation tend to have pelage markings.
- Larger bat colonies are less likely to have pelage markings due to reduced predation risk.
- Pelage markings may function in crypsis through disruptive coloration.
Takeaway
Bats have different fur patterns that help them hide from predators, and these patterns are linked to where they sleep.
Methodology
The study integrated data on roosting ecology and pelage coloration patterns across 914 bat species.
Limitations
The sample sizes for some specific bat types with markings were relatively small.
