TL;DR: Using a unique GPS-tracking database of 803 individuals across 57 species, it is found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in area with a low human footprint.

TL;DR: A comprehensive evaluation of the effects of autocorrelation on home range estimation with a broad array of home range estimators, including Kernel Density Estimation with four bandwidth optimizers and a detailed simulation study to tease apart how sampling frequency, sampling duration, and the focal animal’s movement conspire to affect range estimates.

TL;DR: Examining the effects of group size on ranging patterns and adult female glucocorticoid (stress hormone) concentrations in five social groups of wild baboons over an 11-y period finds evidence that intermediate-sized groups have energetically optimal space-use strategies; both large and small groups experience ranging disadvantages, in contrast to the commonly reported positive linear relationship.

TL;DR: Given the GPS collar's impressive reliability, high spatial accuracy, other associated measurements, and low impact on the study animal, the results indicate the great potential of applying GPS technology to research on wild primates.

TL;DR: Five social groups of wild baboons (Papio cynocephalus) are evaluated, in particular focusing on the spatial determinants of dominance and the consequences of defeat, to offer insight into the influences and consequences of intergroup competition on group-level patterns of space use.
