title: Data from: Latitudinal and seasonal variation in space use by a large, predatory reef fish, Plectropomus leopardus

description: 1. Temperature directly affects the metabolic rate and resource
 requirements of ectothermic animals, which is likely to influence their
 movement and habitat use. Space use is a fundamental component of an
 animal’s ecology and the extent of an animal’s home range has consequences
 for individual distributions, community structure and ecosystem function.
 As ocean temperatures continue to rise as a result of global warming,
 determining the effects of temperature on space use and movement patterns
 of important fisheries species is vital. 2. Our aim was to investigate the
 spatial and temporal variation in space use by a tropical fisheries
 species, the leopard coralgrouper (Plectropomus leopardus) from two
 latitudinally distinct locations on Australia’s Great Barrier Reef (GBR)
 to determine the potential response of large-bodied tropical fishes to
 ocean warming through behavioural modification. 3. Using passive acoustic
 telemetry of 36 tagged individuals, we found that both core use areas
 (50%KUD) and home range extent (95%KUD) varied with respect to location,
 season, body size, and temperature. Average home range extent (95%KUD) for
 tagged P. leopardus was 0.32km2 at the high-latitude location (Heron
 Island) compared to 0.23km2 at the low-latitude location (Opal Reef).
 However, core use areas (50%KUD) did not differ significantly between the
 two locations. 4. Seasonal differences were also apparent at both
 locations with P. leopardus showing contraction in home range extent
 during the summertime. This effect was most pronounced at the low-latitude
 location where home range was significantly reduced during summer when
 temperatures exceeded 27°C. 5. Taken together our findings indicate that
 higher ambient temperature may elicit a sustained and significant decline
 in space use by a commercially important reef fish. Given projected
 increases in ocean temperature due to global climate change, large-bodied
 reef fishes may be increasingly constrained in their movement and space
 use, which will have ramifications for individual fitness, population
 viability, fisheries productivity and ecological function.
description: Monthly home range
 extent (kud95%) of P. leopardusThis file contains data
 for Figure 1. It has core (kud50%) and extent (kud95%) of home range each
 month for each individual at each location. Along with monthly temperature
 profiles for each locationFigure_1.csvCumulative activity space for kud50% and kud95% for P.leopardus from Opal Reef and Heron IslandThis file contains data that produced Figure 2 of the manuscript. It has weekly cumulative activity space metrics for 50%kud (callled 50%.cum) and 95%kud (called 50%.cum) in the spreadsheet for each individual from each locations with corresponding weekly temperature values and fork length.Figure_2.csvFile containing data for the influence of temperature and fork length on kud50% and kud95%This data file contains weekly kud50% and kud95% data for each individual from each location throughout the study period. The arrray.area value in the final column is what was used as a weighting factor within the models to account for variation in receiver numbers and thus the area that the receivers covered.Tag.id is used in the model as the random effect and temp is weekly temperature at each location. This data was used to make Figure3 and FigureSF2.Figures_3_SF2.csvkud50% and kud95% of P. leopardus from Opal Reef and Heron Island at all levels of time (weekly, monthly, overall)This file contains data on the kud50% and kud95% of each individual throughout the sampling period. The 'time' column contains: all, weekly, monthly. All; is the overall kud50% and kud95% values for the individual throughout the study. Weekly; is the average weekly kud50% and kud95% for each individual throughout the study. And monthly; is the average monthly kud50% and kud95% values for each individual throughout the studyFigure_SF3.csvProportional differences in weekly overlap for 50%kud and 95%kudThis data was used to make Figure_SF4. The columns prop.50% and prop.95% are the proportion of overlap of activity space with the week before. A value of 1= complete overlap (no new space used compared with previous week), whereas a value of 0=completely different activity space used compared with the previous week.Figure_SF4.csvMonthly ResidencyThese data assist with calculating monthly residency indices, which is how much time an individual was detected within the array. This is calculated by dividing the number of days an individual was detected at any receiver by the number of days in each month.Monthly.Residency.csv
