Article
Full-text available
Declining coral cover and loss of structural complexity are widely reported on today's coral reefs. While coral loss frequently triggers changes in coral reef fish assemblage structure, the ecosystem‐scale consequences of these changes are poorly known. Here we evaluate how four metrics of energy flow and storage that underscore a critical coral re...

For the last seven decades, cleaning sym-biosis in the marine environment has been a research field of intrigue. There is substantial evidence that, by removing undesired items from their client fishes, cleaner organisms have positive ecosystem effects. These include increased fish recruitment, abundance and enhanced fish growth. However, the intim...
Article
Full-text available
Cleaner fish remove parasites from other organisms, called clients. While there is an extensive body of work on the positive role of cleaners for their clients and reef communities, remarkably, potential parasites hosted by specialised cleaner fishes themselves have not been explored. In this study, we surveyed the parasite community of the Indo-Pa...
Article
Cleaning symbiosis is critical for maintaining healthy biological communities in tropical marine ecosystems. However, potential negative impacts of mutualism, such as the transmission of pathogens and parasites during cleaning interactions, have rarely been evaluated. Here, we investigated whether the dedicated bluestreak cleaner wrasse Labroides d...
Article
Full-text available
Cleaner fishes remove parasites from other fishes called “clients,” thereby contributing to a healthier ecosystem. Although the behavior and learning abilities of dedicated and tropical cleaner fishes have been broadly studied, a limited number of studies investigated the behavior of facultative and temperate cleaner fishes and, to the best of our...
Article
Connectivity between habitats and ecological communities is a critical component of trophic structure. Coral reef systems include reef, seagrass, and mangrove habitats, and the movement of fishes is a key component of habitat connectivity among them. Fishes that undergo diel migrations between habitats are among the best-studied functional groups....
Article
Full-text available
In marine interspecific cleaning mutualisms, small fish known as “cleaners” inspect the surface, gills and sometimes the mouth of “client” reef fish, eating ectoparasites, mucus, scales and dead or infected tissue. These cleaner fish species share similar vivid coloration that makes them recognizable by clients. To gain insight on additional commun...
Article
Full-text available
Widespread coral mortality is leading to coral reef degradation worldwide. Many juvenile reef fishes settle on live coral, and their predator-avoidance behaviour is disrupted in seawater exposed to dead corals, ultimately increasing predation risk. Gnathiid isopods are micropredatory fish ectoparasites that occur in higher abundances in dead coral....
Article
Aim Several drivers explain the global distribution of all reef fish. However, whether these drivers also explain the distribution and traits of a functional subgroup involving cleaner fishes remain unclear. Here we examine the variation in traits of cleaner fishes and test whether historical, environmental, ecological and geographical drivers are...
Article
Full-text available
Gnathiid isopods, common fish ectoparasites, can affect fish physiology, behaviour and survival. Gnathiid juveniles emerge from the benthos to feed on fish blood. In the Caribbean, gnathiids are positively associated with dead coral and negatively associated with live coral, due to coral predation on gnathiids. However, such interactions were unstu...
Article
Full-text available
Cleaner fishes remove ectoparasites, mucus and dead tissues from other ‘client’ organisms. These mutualistic interactions provide benefits for the ‘clients’ and, on a larger scale, maintain healthy reef ecosystems. Here, we report two species of angelfishes, Centropyge bicolor and C. tibicen, acting as cleaners of the blue tang Paracanthurus hepatu...
Article
Parasites can account for a substantial proportion of the biomass in marine communities. As such, parasites play a significant ecological role in ecosystem functioning via host interactions. Unlike macropredators, such as large piscivores, micropredators rarely cause direct mortality. Rather, micropredators impose an energetic tax, thus significant...
Article
The reliance of parasites on their hosts makes host-parasite interactions ideal models for exploring ecological and evolutionary processes. By providing a consistent supply of parasites, in vivo monocultures offer the opportunity to conduct experiments on a scale that is generally not otherwise possible. Gnathiid isopods are common ectoparasites of...
Article
Full-text available
Mass coral bleaching events due to rising seawater temperatures are occurring with increasing frequency and are among the most conspicuous consequences of human-induced climate change. While bleaching events have clear impacts on the corals themselves, the impacts on other organisms and on the overall reef community are more difficult to assess. Th...
Article
Full-text available
The lizardfish Synodus saurus is a common demersal predator in Azorean waters, occurring over soft sandy to muddy substrates. As many other fish species, it is often infested by the parasitic isopod Anilocra physodes, an haemathophagous ectoparasite. In a sample of 310 lizardfish, 237 were infested by A. physodes, in a ratio of 1.3 parasites/fish....
Article
Full-text available
Cleaner fishes are key contributors to the health of fish communities. However, available information mostly refers to tropical systems, while very fewer studies have compared the activity of cleaner fish that inhabit temperate ecosystems. Facultative cleaner fish are assumed to clean only as juveniles and having a broader diet than obligatory clea...
