Summary: Biodiversity is declining worldwide, food web are being altered and of concern are the loss of large carnivores. Among the many threats they face, climate change is expected to become a major pressure as it has the potential to strongly disrupt predator-prey interaction. Predator hunting mode (ambush versus cursorial) is an important feature of predation as it plays a key role in the strength of the predator impact on the demography of its prey population. Here, I explored how predator hunting mode can potentially modulate the impacts of climate change on predators and their prey populations. To do so, I simulated climate change scenarios, and explored their consequences for two predators exhibiting different hunting mode and preying on density-dependent prey population. This study revealed that its hunting mode affects a predator response to climate change, affecting the link between short and long-term responses and the strength of the long term response. This constitutes a first step towards an improved understanding of predators-prey relationships in a changing climate.
