Most mutually beneficial social interactions (cooperation within species, mutualism between
species) involve some degree of partner choice. In an analogy to economic theory as …

Signal theory predicts organisms should evolve signals that are conspicuous to intended
receivers in natural signalling environments. Cleaner shrimps remove ectoparasites from …

Ecologists have long sought general explanations for the co‐occurrence of ecologically
similar taxa. Niche theory explains co‐occurrence via functional differences among taxa that …

Because they serve as the main architects of coral reefs, the distribution and abundance of
stony coral species have major impacts on other associated community members. Thus …

Understanding the behaviour and ecological role of elasmobranchs is essential for their
conservation, particularly in regions harbouring threatened and data-deficient species like …

Animal cognition is deeply influenced by interactions with the environment. A notable
example of sophisticated cognition in the animal kingdom is described by the mutualistic …

The cleaning symbiosis in coral reef fish is one of the most remarkable mutualist marine
interactions; the main actors are cleaner and client fishes, that communicate via tactile and …

We observed a novel, nocturnal cleaning interaction between a cleaner shrimp (Genus
Urocaridella) and the giant moray eel (Gymnothorax javanicus) on a lagoonal patch reef in …

A variety of animals have been observed cleaning ectoparasites off of another species. In
terrestrial systems, the most common interactions involve birds cleaning mammals. Despite …

The vast majority of interspecific interactions are competitive or exploitative. Yet, some
positive interspecies interactions exist, where one (commensalism) or both (mutualism) …
