Bat Community Composition and Post‐Departure Degradation Patterns of eDNA Shed by Migratory Cave Bats

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
This study evaluated airborne environmental DNA (eDNA) as a non‐invasive tool for monitoring the endangered Mexican long‐nosed bat (Leptonycteris nivalis) and other cave‐dwelling bats by examining how eDNA detections persisted after the bats' seasonal departure and varied throughout the cave.

High‐Speed Altitude Regulation With Neuromorphic Camera and Lightweight Embedded Computation

Advanced Intelligent Systems, Volume 8, Issue 6, June 2026.
Neuromorphic cameras deliver rapid, high‐dynamic‐range sensing but overwhelm embedded processors at high speeds. This work presents a lightweight, optimized Lucas–Kanade optical flow method with parallelization, gyroscopic derotation, and adaptive event slicing.
