Exotic axis deer appeared more behaviorally flexible than native brocket deer
WHAT THE EVIDENCE SAYS
From July 2022 to January 2024, camera traps at La Esmeralda documented higher relative detection of introduced Axis axis and broader activity times than native Subulo gouazoubira, which was more consistently crepuscular. Temporal overlap remained high; the researchers noted possible habitat competition rather than documenting it experimentally.
WHY IT MATTERS / OUR READ
Long-term invasion assessments need to track native species, productive-landscape exposure and time-of-day habitat use, not simply abundance of the newcomer.
CAVEATS / UNCERTAINTY
Only two camera stations served each habitat type at one protected area. Relative detections and modeled local densities are not regional population trajectories, and competition remains an inference.

Camera traps in an Argentine protected area found more axis deer records and broader activity timing, but did not demonstrate competitive displacement.
