Are neotropical cave-bats good landscape integrity indicators? Some clues when exploring the cross-scale interactions between underground and above-ground ecosystems

Neotropical caves located in pristine ecosystems harbor high biodiversity but face functional shifts and degradation interlinked with aboveground changes. Cave-roosting bats have been proposed as integrity indicators of karst landscapes considering their sensitive to both the underground and abovegr...
