Top predators shape the communities of sympatric predators by killing and displacing smaller predators. Predation risk pushes smaller predators to select enemy-free spaces irrespective of food availability, which results in changes in their behaviour, space use, distribution, and abundance. Although the landscape of fear dynamics are known for top predators such as the eagle owl and its impact on smaller raptors, the effect of the presence and abundance of the eagle owl on the space use of mesopredator carnivores remains poorly understood. Here, we studied this effect on the space use of the stone marten in a Mediterranean ecosystem where it shares rabbits as main prey with the eagle owl. We also accounted for the presence of another sympatric carnivore, the red fox. Using a multi-model inference, we found stone martens avoided areas with a higher abundance of eagle owls and rabbits, which suggested a hyperpredation process and a cognitive association by stone martens between rabbit hotspots and owl presence. We found a positive relationship between the space use of the red fox and the stone marten, which suggested foxes behaved as competitors and not predators of martens. Understanding intraguild predation can assist the conservation and management of predators and their prey.

In this study the nesting biology of Podocnem is unifilis was investigated from July to November 1998 at the Mamirauá Sustainable Development Reserve, located in the Solimões river, near Tefé, Amazonas, Brazil. Podocnemis unifilis nested in August and September, with the hatching event occurring in October and November. Nests were excavated in clay soils (67.5%), sand (25%), and leaf litter (7.5%). Hatching success was highest in the sand beach nests and lowest in the clay banks nests. Humans and the tegu lizard (Tupinambis) were the main egg predators. This turtle population can recover only by the protection of nesting beaches, educational programs for the in habitants of the Reserve, participation of the community in the conservation and management program , and permanent guarding of the nesting beaches by Instituto Brasileiro do Meio Ambiente e Dos Recursos Naturais Renováveis-IBAMA authorities.
