Feeding and movement locations of herbivorous coral reef fishes on Lizard Island

This dataset contains the raw data associated with the following publication:Streit, R.P., Cumming, G.S., Bellwood, D.R. (2019) Patchy delivery of functions undermines functional redundancy in a high diversity system. Functional EcologyThe dataset details geo-referenced feeding and movement locations of individual herbivorous coral reef fishes. Fishes are classed to species and grouped into functional groups (following Bellwood et al. 2019). Data was gained from visually analysing video recordings from 5 sites (sites A to E) in Mermaid Cove, Lizard Island, Australia. Sites encompassed 36 square-meters and were covered by 8 GoPro cameras.Fish locations were visually triangulated from videos (with the help of high-detail benthic maps) and were assessed to have an accuracy of 17 centimeters. Videos for these data were collected in April 2017. Data was collected in order to identify fish feeding locations in fine detail over extended spatial scales. Based on this data, feeding areas were claculated and overlap of feeding areas (across functional groups) calculated. Details on included variables:FISH_ID:                               an individual code for each observed fish (code for species, followed by numerical code)FAMILY / GENUS / SPECIES:    taxonomic identity of each fishFUNCTIONAL GROUP:             functional group classification for each fish, following Bellwood et al. 2019ESTIMATED_TOTAL_LENGTH:  estimated total length for each fish, estimated by one observer from video dataFEEDING_Y_N:                      code for fish behaviour, "Y" = fish is feeding, "N" = fish is movingSITE:                                    code for one of the five study sites (all located within Mermaid Cove, Lizard Island, Australia)X- / Y-COORD:                       geo-referenced x- and y- coordinate for each fish observation (projection: WGS 84/UTM 55S)TIME_SEC:                            time of each observation in sec after start of video analysis (30 minutes after video recording started) Reference: Bellwood, D.
