“…reported by Setchell (1924), all species recorded here represent new records for the Rose Atoll MNM. In addition to this contribution, Kenyon et al (2010) provided an updated characterization of the coral fauna at Rose Atoll based on observations made during the NOAA, Pacific RAMP, CRED expeditions to American Samoa reported here. The accumulation of baseline information on the biodiversity of the marine plants and animals and on their interaction within this isolated Marine National Monument is important to its reef conservation.…”

Annotated checklist for stony corals of American Sāmoa with reference to mesophotic depth records

An annotated checklist of the stony corals (Scleractinia, Milleporidae, Stylasteridae, and Helioporidae) of American Sāmoa is presented. A total of 377 valid species has been reported from American Sāmoa with 342 species considered either present (251) or possibly present (91). Of these 342 species, 66 have a recorded geographical range extension and 90 have been reported from mesophotic depths (30–150 m). Additionally, four new species records (AcanthastreasubechinataVeron, 2000,FavitesparaflexuosusVeron, 2000,EchinophylliaechinoporoidesVeron & Pichon, 1980,TurbinariairregularisBernard, 1896) are presented. Coral species of concern include species listed under the US Endangered Species Act (ESA) and the International Union for Conservation of Nature’s (IUCN) Red List of threatened species. Approximately 17.5% of the species present or possibly present are categorized as threatened by IUCN compared to 27% of the species globally. American Sāmoa has seven ESA-listed or ESA candidate species, includingAcroporaglobiceps(Dana, 1846),AcroporajacquelineaeWallace, 1994,Acroporaretusa(Dana, 1846),Acroporaspeciosa(Quelch, 1886),Fimbriaphylliaparadivisa(Veron, 1990),Isoporacrateriformis(Gardiner, 1898), andPocilloporameandrinaDana, 1846. There are two additional species possibly present, i.e.,Pavonadiffluens(Lamarck, 1816) andPoritesnapoporaVeron, 2000.

“…Monitoring of fish communities showed that the abundance and biomass of herbivorous reef fishes, particularly that of surgeonfishes and unicornfishes, was far higher in the vicinity of the wreck than in other areas of the atoll, which was attributed to the bloom of cyanobacteria and algae (Schroeder et al, 2008). In recent years, since debris removal has been completed and metallic sources of enrichment have been eliminated, invasive algae and cyanobacteria have declined and corals have started to recover (Kenyon et al, 2010;Pendleton, 2012). These examples show a promising level of resilience in these coral reef systems, both to natural (Mo'orea) and anthropogenic (Rose Atoll) disturbances and in both inhabited and fished (Mo'orea) and remote and protected (Rose Atoll) systems.…”

Herbivorous Fish Populations Respond Positively to a Shipwreck Removal and Associated Alteration of Benthic Habitat

2018

View full text Add to dashboard Cite

Shipwrecks can have significant localized effects when grounded on shallow coral reefs. These effects are not limited to the immediate physical damage, but can have widespread and lasting impacts due to alteration of the chemical makeup of the surrounding water column. This can subsequently impact the growth of benthic organisms, often leading to phase shifts and high levels of mortality of corals in the vicinity of the wreck. At Palmyra atoll, the grounding of a longline fishing vessel on the shallow reef terrace is associated with a phase shift to the corallimorph, Rhodactis howesii. In 2013, a wreck removal effort initiated by the US Department of Fish and Wildlife resulted in the successful extraction and disposal of the wreckage, after which the density and percent cover of R. howesii in the immediate vicinity of the wreck site dropped precipitously. Here, we document the response of the fish community to the wreck removal and localized decline in R. howesii. We show that the biomass of scarid parrotfishes and acanthurid surgeonfishes and unicornfishes (primarily herbivores) increased after the removal of the wreck, while biomass of chaetodontid butterflyfishes (primarily invertivores, many species are known to feed on coelenterate polyps) declined over the study period. The density of small scarids and acanthurids also increased, but only after a few years post removal. Overall these results indicate that Palmyra's unfished herbivore population has rapidly responded to the removal of the wreck and associated decrease in corallimorph cover, can maintain high levels of grazing where space is made available for colonization of early successional algae species, and may have the potential to facilitate reef recovery.
