Animals' daily activity patterns are influenced by external factors like habitat selection, food availability and competition with individuals or species. Trade-offs between foraging and predation risk drive ungulate resource selection. Therefore, ungulates' avoidance of predators and humans should influence their activity patterns and space use. In order to fully understand how humans, predators, and prey interact, as well as how interspecific activity patterns and spatial use overlap, it is essential to understand the three-way interaction between them. In our study, we intended to evaluate effects of human presence throughout the landscape on the interactions between Eurasian lynx (Lynx lynx) and wild ungulates, and the predator-prey relationship. In order to achieve this, we conducted systematic monitoring in seven regions within the Western Carpathians between 2014 and 2021 using camera traps. We hypothesized that ungulates should be avoiding predators and should actively match their habitat use with humans ("human shield hypothesis”). Our results revealed a significant positive influence of humans on the occurrence of roe deer and a negative effect of lynx on this species. In contrast to our expectations, we did not reveal the influence of human activities on lynx presence. We did not find any significant effects of humans and lynx on red deer and wild boar, respectively. Based on our findings, we can conclude that roe deer may use human shields to avoid predators during winter.
