Who’s active when and where? Unraveling the habitat use and temporal strategies of prey in a predator-human shared landscape
Understanding the habitat use and temporal activity patterns of key prey species is crucial for conserving large carnivores, such as tigers and leopards, especially in landscapes dominated by humans. Hence, this study investigated the habitat associations and diel activity overlaps of six major prey species with both predators and humans in Banke National Park (BaNP), Nepal. For this, we deployed camera traps (n = 30) along a 2 km × 2 km grid, resulting in a total sampling effort of 450 trap nights. Generalized linear mixed models were used to reveal species-specific habitat associations. Barking deer were found associated with areas of sparse vegetation and proximity to water while avoiding roads; in contrast, spotted deer tolerated higher levels of human disturbance. Similarly, four-horned antelopes avoided steep slopes, wild boars were less common near roads, and Indian crested porcupines preferred regions with low disturbance. Temporal activity analyses indicated diverse activity patterns among prey, ranging from crepuscular to nocturnal, with most species exhibiting moderate overlap with predator activity. The reduced temporal synchrony noted for spotted deer and four-horned antelopes supports the human shield hypothesis, suggesting that these species alter their activity in response to increased human presence to mitigate predation risk. Conversely, predators minimized their temporal overlap with humans, likely as an adaptive strategy to avoid encounters. These findings signify the necessity for species-specific habitat management to sustain prey populations and mitigate human-wildlife conflict. We recommend conducting further studies to gather year-round data that will provide a thorough understanding of how seasonal changes influence the activities of prey and their predators in the study area and similar landscapes.
期刊介绍:
Global Ecology and Conservation is a peer-reviewed, open-access journal covering all sub-disciplines of ecological and conservation science: from theory to practice, from molecules to ecosystems, from regional to global. The fields covered include: organismal, population, community, and ecosystem ecology; physiological, evolutionary, and behavioral ecology; and conservation science.
