FlockSeer: A portable stereo vision observer for bird flocking

open access: yesIET Cyber-Systems and Robotics, Volume 6, Issue 3, September 2024.
Abstract Bird flocking is a paradigmatic case of self‐organised collective behaviours in biology. Stereo camera systems are employed to observe flocks of starlings, jackdaws, and chimney swifts, mainly on a spot‐fixed basis. A portable non‐fixed stereo vision‐based flocking observation system, namely FlockSeer, is developed by the authors for observing

Unravelling the complexities of biotic homogenization and heterogenization in the British avifauna

open access: yesJournal of Animal Ecology, Volume 93, Issue 9, Page 1288-1302, September 2024.
Biotic homogenization, the process of assemblages becoming more similar over time, is predicted to increase in the future due to increased anthropogenic disturbance. Here, the authors show that in studies of spatial diversity change, incorrect inferences may be reached if species identities are not considered.
