Insights into the spatial ecology of severely injured free‐living felids: Iberian lynx, bobcat, and snow leopard

Abstract

Severe musculoskeletal diseases, such as those associated with congenital or traumatic events, that result in missing limbs may compromise the fitness and survival of free‐living felids. Here we report the space use of four amputee individuals from three felid species captured from 2017 to 2022 in Missouri (USA), Toledo and Badajoz (Spain), and Suitai Khairkhan Mountain (Mongolia). We describe home ranges and daily travel distances post‐release of free‐living felids that had either suffered a traumatic amputation or following a surgical amputation. We compared these data with those reported in the literature for felids without amputations. Forelimb or hindlimb amputation did not affect the hunting, mating, or territory patrolling behavior of any of the individuals. However, we recorded significant differences in the daily movement before and after the traumatic event of the Iberian lynx forelimb amputee. We attribute this difference to the physical impairment, although we consider other variables that may have played a role. Nevertheless, all animals appeared to cope well with their limb loss, showing home ranges and daily distances within those recorded for their sex and species. Unless amputee felids represent a threat to domestic livestock or humans, our data suggest these individuals may remain free‐living as they contribute to local population persistence and appear to maintain good general health and welfare.

Abstract

As a result of anthropogenic pressures, wild felids worldwide may suffer from severe lesions that may impact their overall fitness, behavior, and/or survival. Despite the severity of skeletal trauma that resulted in limb amputation, two Iberian lynxes, one bobcat, and one snow leopard tagged with telemetry collars didn't show differences in movement patterns compared with healthy conspecifics, highlighting the resilience, adaptation, and plasticity of these individuals.
