Sex drives intraspecific scaling of home range size in mammals

This dataset contains derived home range estimates from individual-level GPS tracking data of 349 resident mammals across 18 species in Brazil, as well as individuals' body mass, sex, and habitat quality estimations. The dataset was compiled to investigate intraspecific variation in home range (HR) size and its relationship with body mass (BM) and sex. The study addresses a key knowledge gap in movement ecology: while interspecific allometric scaling of mammal home ranges is well documented, it is unclear whether the same patterns hold within species and for both sexes. This dataset and the associated code allow researchers to reproduce the analyses made by Giroux et al., visualize results, explore sex-specific and species-specific patterns, and integrate these data into broader comparative studies.
, Animal data collection
We conducted this study across savanna and grassland ecosystems in Brazil (S 58°11'40\" - 46°9'50\", W 16°9'27\" - 32°20'54\"), under a tropical climate. The studied landscapes were composed of mosaics of natural forested and non-forested areas (e.g., woody and shrubby savannas, and open natural grasslands) as well as anthropogenic land uses such as exotic forests, crops (mainly rice and soybean), pasture, and highways. From 2007 until 2024, we captured, sexed, weighed, and GPS tracked 349 adult, healthy, free-living individuals, encompassing 18 mammal species from 9 families and 5 orders. The monitored species were puma (Puma concolor; 5 females and 15 males), ocelot (Leopardus pardalis; 5 females and 6 males), Geoffroy’s cat (Leopardus geoffroyi; 17 females and 9 males), margay (Leopardus wiedii; 5 females and 6 males), jaguar (Panthera onca; 13 females and 8 males), crab-eating fox (Cerdocyon thous; 14 females and 19 males), hoary fox (Lycalopex vetulus; 9 females ..., # Sex drives intraspecific scaling of home range size in mammals

## Description of the data and file structure

Understanding variation in home range size (HR) provides important insights into the underlying ecological processes driving space use. At an interspecific level, HR is expected to scale with body mass because larger animals can move further and need more resources. We aimed to investigate whether the interspecific allometric scaling of mammals’ HR is also observed at an intraspecific level, and the influence of individuals’ sex on both HR and HR scaling. 

The dataset contains derived home range estimates from individual-level GPS tracking data of 349 resident mammals across 18 species in Brazil, as well as individuals' body mass, sex, and habitat quality estimations. Considering the uncertainty of HR estimations, we used a Bayesian approach to estimate the relationship between HR and BM, invest...,
