Ecosystem engineering research has recently demonstrated the fundamental importance of non-trophic interactions for food-web structure. Particularly, by creating benign conditions in stressful environments, ecosystem engineers create hot beds of elevated levels of recruitment, growth, and survival of …

Recently, Lévy walks have been put forward as a new paradigm for animalsearch and many cases have been made for its presence in nature. However,it remains debated whether Lévy walks are an inherent behavioural strategyor emerge from the animal reacting to its habitat. Here, we demonstratesignatures …
