Tidal-diel patterns of movement, activity and habitat use by juvenile mangrove whiprays using towed-float GPS telemetry

Brief description

Stingrays are a relatively diverse and widespread group of elasmobranchs. Despite their ecological and economical importance, many aspects of stingray ecology remain poorly understood. Few studies have examined juvenile stingrays fine-scale movements within nursery areas. This study aimed to examine diel movement patterns in juvenile mangrove whiprays (Urogymnus granulatus) using towed-float GPS telemetry within a reef flat habitat of the Great Barrier Reef.

The dataset consists of an Excel spreadsheet including GPS tracks of 10 young-of-the-year and juvenile (3 males and 7 females) mangrove whiprays. Tracking occured between 2016 and 2017. Two individuals were tracked twice, thus a total of 12 tracks were analyzed, five during the day and seven at night, ranging from 1.35 to 9 hours.

Tracking data were analysed using the adehabitatLT, adehabitatHR and glmmTMB packages in R.

Disc width and Tide height values are in cm; Tank time and duration of track in h; Total displacement in m; Activity space in km² ; Rate of Movement in m min^-1
