Tanks offer significant flexibility for aquaculture production. When in an optimally operated
water reuse configuration, they enable farming of most, if not all species of fish, in …

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

More than 100 years ago, the biologist Jakob von Uexküll suggested that, because sensory
systems are diverse, animals likely inhabit different sensory worlds (umwelten) than we do …

Evolutionary biologists typically envision a trait's genetic basis and fitness effects occurring
within a single species. However, traits can be determined by and have fitness …

A comprehensive framework for understanding species coexistence Coexistence is the
central concept in community ecology, but an understanding of this concept requires that we …

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 …

Colour change is used by a wide range of animals. It is used for intra‐and interspecific
communication and crypsis, and can occur on morphological and physiological levels. Bony …

Cleaning interactions, in which a small 'cleaner'organism removes and often consumes
material from a larger 'client', are some of the most enigmatic and intriguing of interspecies …

Many animal species can rapidly change their body colouration and patterning, but often the
ecological drivers of such changes are unknown. Here, we explored dynamic colour change …
