Zooxanthellae symbiotic with stony corals utilise ammonium excreted by resident fish populations. However, the contribution of ammonium produced by anemonefishes to host sea anemones has not been examined. In split-pair laboratory experiments with the giant sea anemone Entacmaea quadricolor, one half of each sea anemone was maintained with two individuals of the endemic anemonefish Amphiprion bicinctus, and the other half was maintained without anemonefish. Sea anemone fragments maintained with… Expand
Benefits to host sea anemones from ammonia contributions of resident anemonefish
TLDR
It is concluded that, in this multi-level mutualism, ammonia supplements provide essentially the same level of physiological contribution to host anemones and zooxanthellae as do live resident fish. Expand
Effects of anemonefish on giant sea anemones: expansion behavior, growth, and survival
TLDR
It is concluded that host sea anemones sense the presence of symbiotic anemonefish via chemical and/or mechanical cues, and react by altering their expansion behavior, resulting in their shrinkage and eventual death. Expand
Effects of anemonefish on giant sea anemones: expansion behavior, growth, and survival
The symbiosis between giant sea anemones and anemonefish on coral reefs is well known, but little information exists on impacts of this interaction on the sea anemone host. On a coral reef at Eilat,Expand
Anemonefish facilitate bleaching recovery in a host sea anemone
TLDR
Anemonefishes give their host sea anemones a distinct ecological advantage by enhancing resilience to bleaching, highlighting the benefits of symbioses in a changing climate. Expand
Ammonia flux, physiological parameters, and Symbiodinium diversity in the anemonefish symbiosis on Red Sea coral reefs
TLDR
It is concluded that in the field, anem onefish excrete ammonia at rapid rates that correlate with elevated concentrations among host anemone tentacles, in contrast to laboratory manipulations where removal of fish causes anemones to shrink and Symbiodinium to become less abundant. Expand
Asexual Propagation of Sea Anemones That Host Anemonefishes: Implications for the Marine Ornamental Aquarium Trade and Restocking Programs
TLDR
Asexual propagation as a method for culturing a geographically widespread and commonly traded species of host sea anemone, Entacmaea quadricolor, is examined to establish whether size or colour morph influenced survival after cutting into halves or quarters and whether feeding was needed to maximise survival and growth after cutting. Expand
Nutrient transfer in a marine mutualism: patterns of ammonia excretion by anemonefish and uptake by giant sea anemones
TLDR
Zooplanktivorous fishes that form mutualisms with coral reef cnidarians may serve as an important link between open water and benthic ecosystems, through the transfer of large quantities of nutrients to zooxanthellate hosts, thus enhancing coral reef productivity. Expand
Anemonefish oxygenate their anemone hosts at night
TLDR
It is concluded that physical contact between anemonefish and sea anemones elevates the of at least one of the partners at night, and anem onefish behavior at night appears to oxygenate sea anEMone hosts and to augment the metabolism of both partners. Expand
Anemonefish depletion reduces survival, growth, reproduction and fishery productivity of mutualistic anemone–anemonefish colonies
TLDR
The relationship between E. quadricolor and A. melanopus is not only obligate, but also demographically rigid and easily perturbed by anemonefish fisheries, and several tangible management actions are proposed that will help to minimize fishing effects. Expand
Anemonefish personalities influence the strength of mutualistic interactions with host sea anemones
TLDR
Investigating the effect of four variables (fish number, fish biomass, fish shyness, and anemone colony area), on anem one growth and asexual reproduction suggests that behavioral variation among individual fish may be an important driver of anemones growth. Expand

Primary site and initial products of ammonium assimilation in the symbiotic sea anemone Anemonia viridis
TLDR
Ammonium uptake by the symbiotic sea anemone Anemonia viridis was examined by following the pathway of assimilation using 15N-enriched ammonium, and it was found that glutamate was metabolised most rapidly by zooxanthellae, followed by aspartate, alanine, glycine, phenylalanine, valine, tyrosine, and leucine from zooxanhellae.

Costs and benefits of the symbiosis between the anemoneshrimp Periclimenes brevicarpalis and its host Entacmaea quadricolor
TLDR
There IS a benefit to the shrimp from this association and potentially a cost to the anemone, but anemones w ~ t h shrimp in nature always appear to have normally long and numerous tentacles. Expand
Uptake and assimilation of 15N-ammonium by the symbiotic sea anemones Bartholomeaannulata and Aiptasiapallida: conservation versus recycling of nitrogen
TLDR
Although there was little support for nitrogen recycling in studies, there is likely a continuum between the recycling and conservation paradigms that depends on the availability of photosynthate and hence the coupling between carbon and nitrogen cycles of the partners. Expand
Host feeding and nutrient sufficiency for zooxanthellae in the sea anemone Aiptasia pallida
TLDR
Algal populations in unfed anemones gradually decreased, indicating that zooxanthellae were lost faster than they were replaced by division, and whether algae are nutrient-limited in hosts under field conditions has not been examined fully. Expand
Juvenile production of Amphiprion bicinctus (Pomacentridae, Teleostei) and rehabilitation of impoverished habitats
TLDR
It would appear that the method of production in captivity followed by resettlement in impoverished natural habitats may be effective for community rehabilitation of Amphipnon bicinctus juveniles. Expand
The effect of external nutrient resources on the population dynamics of zooxanthellae in a reef coral
TLDR
The results are consistent with the hypothesis that the growth of zooxanthellae in S. pistillata from the Red Sea is nitrogen limited, suggesting that availability of inorganic nitrogen leads to increased protein synthesis in zooxanhellae. Expand
Supply of regenerated nitrogen to sea anemones by their symbiotic shrimp
TLDR
Anemones associated recently with a shrimp demonstrated an enhanced capacity to take up external ammonia, compared with anemones not recently associated with arimp, and their tissues contained more zooxanthellae. Expand
Ammonium contribution from boring bivalves to their coral host--a mutualistic symbiosis?
TLDR
The results indicate a possible pathway in the biogeochemical cycle of nitrogen in the coral reef environment and suggest the association between L. slmplex and A. myriophthalma may also be an example of mutualistic symbiosis. Expand
Effects on growth and reproduction of the coral Stylophora pistillata by the mutualistic damselfish Dascyllus marginatus
TLDR
It is demonstrated that the branching coral Stylophora pistillata (Esper) benefits, in two components of coral fitness, from the presence of the damselfish Dascyllus marginatus (Rüppell), an obligate coral dweller. Expand
