Dataset

Description

Sighting histories_juveniles&adults_Robust Design models:
This file contains the monthly sighting histories of 205 marked juvenile and adult bottlenose dolphins sighted off the east coast of Scotland between 1989 and 2015, and used to estimate survival rate using a robust design modelling framework. The file can be imported into RMark, and then converted to an .inp file to fit mark-recapture models (using MARK software). Time intervals (i.e. primary and secondary occasions) for robust design analysis are given in the file "time.intervals.txt"

Sighting histories_Sex-specific Juveniles&Adults_Multistate models:
This file contains the annual sighting histories of 205 marked juvenile and adult bottlenose dolphins sighted off the east coast of Scotland between 1989 and 2015, used to estimate sex-specific survival rates using multi-state models. Information on sex is provided so that U=unknown, M=male and F=female, 0=not sighted. The file can be imported into RMark, and then converted to an .inp file to fit mark-recapture models (using MARK software).

Sighting histories_calf_age CJS models:
This file contains the annual sighting histories of 56 bottlenose dolphin calves sighted off the east coast of Scotland between 1990 and 2015, and used to estimate age specific survival rates up to 3 years of age. The sighting histories are restricted to calves whose mothers were seen in the three years following birth. The file can be imported into RMark, and then converted to an .inp file to fit mark-recapture models (using MARK software) .

Sighting histories_adults only_Robust Design models:
This file contains a restricted dataset of only adult bottlenose dolphins, sighted off the east coast of Scotland between 1989 and 2015. The monthly sighting histories were used to investigate if the detected trend in juvenile&adult survival was more likely a change in adult or juvenile survival. The file can be imported into RMark, and then converted to an .inp file to fit mark-recapture models (using MARK software). Time intervals (i.e. primary and secondary occasions) for robust design analysis are given in the file "time.intervals.txt"

Time intervals for Robust Design models:
This file contains the time intervals (primary and secondary occasions) defined for the datasets JuvAd_Robust design models.txt and Adult only_Robust design models.txt. These time intervals are defined to use in RMark package when fitting mark-recapture models.
