Exceptional Visual‐Opsin Coexpression and Phenotypic Diversity in Outer‐Retinal Photoreceptors of Caenophidian Snakes

open access: yesJournal of Comparative Neurology, Volume 533, Issue 10, October 2025.
In snakes, profound differences in retinal architecture are observed between diurnal and nocturnal species. Additionally, in the rod‐dominated retinas of nocturnal snakes, coexpression of the cone opsins SWS1 and LWS in individual cones is common, while rhodopsin (RH1) is restricted to typical rods.

Object detection‐assisted workflow facilitates cryptic snake monitoring

open access: yesRemote Sensing in Ecology and Conservation, Volume 11, Issue 5, Page 606-617, October 2025.
Camera traps are powerful tools used to study animals. However, camera trap studies often produce large datasets requiring labor‐intensive classification. While many object detection models have been developed to facilitate image analysis, their efficacy when presented with novel species and systems is poorly understood.
