Challenge
Do the dune's mammals split the day to stay out of each other's way? Compare the round-the-clock activity of the rabbit, red fox and fallow deer, and decide whether their busy hours overlap or stagger (temporal niche partitioning).
- Where to start
- Read observations.csv from inside each of pilot1.zip, pilot2.zip and pilot3.zip (Camtrap DP format, no need to touch the images), concatenate them, and keep rows where observationType == 'animal'. Get the local hour from the eventStart string (characters 11-13, e.g. the '19' in '2022-03-09T19:30:18+0100'), then for the top species by scientificName - Oryctolagus cuniculus (rabbit), Vulpes vulpes (fox), Dama dama (fallow deer) - count detections per hour and normalise each species to its own total.
- What to share
- Activity-by-hour curves (and/or a 24-hour polar clock) for the three main species with the night band marked, plus a short note on which species is nocturnal vs crepuscular and whether their peak hours separate. Bonus: split by season using the eventStart month, or compare individual cameras via deploymentID.
