We welcome the comment by Heymann & Fuzessy to our recent paper onpalm fruit colours and primate colour vision. Heymann & Fuzessy question whether palms (Arecaceae) are a good model system to understand thediversification of (trichromatic) primates. We used a macroecological and macro-evolutionary comparative …

A long-standing hypothesis in ecology and evolution is that trichromatic colour vision (the ability to distinguish red from green) in frugivorous primates has evolved as an adaptation to detect conspicuous (reddish) fruits. This could provide a competitive advantage over dichromatic frugivores which …

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 …
