How long do anti-predator interventions remain effective? Patterns, thresholds and uncertainty

摘要: Human-predator conflicts are globally widespread, and effective interventions essential to protect human assets from predator attacks. As effectiveness also has a temporal dimension, it is of importance know how long remain most determine time thresholds at which begins decrease. To address this, we conducted systematic review the changes in non-invasive against terrestrial mammalian predators, defining trend line for each published case. We found only 26 cases 14 publications, mainly referring electric fences (n = 7 cases) deterrents cases). calving control highly longest time, reducing damage by 100% periods between three months 3 years. The acoustical light as well guarding animals eroded quite fast after one five months. Supplemental feeding was be counter-productive increasing over instead it. stress that vital make monitoring routine requirement all intervention applications suggest standardize can produce meaningful affordable information.
