“…Consistent with observations of the monogenean fauna of Palmyra Atoll fishes (Vidal-Martínez et al 2017), parasitic copepod richness at Palmyra Atoll qualitatively appears low relative to other localities in the Indo-Pacific region. Most of the fish species we examined (30 of 44) were not parasitized by copepods, even with large sample sizes for some fish species (e.g.…”

We surveyed copepods parasitic on the fishes at Palmyra, a remote atoll in the Central Indo-Pacific faunal region. In total, we collected 849 individual fish, representing 44 species, from the intertidal lagoon flats at Palmyra and recovered 17 parasitic copepod species. The parasitic copepods were:OrbitacolaxwilliamsionMulloidichthysflavolineatus;AnuretesserratusonAcanthurusxanthopterus;CaligusconfususonCarangoidesferdau,Carangoidesorthogrammus,Caranxignobilis,Caranxmelampygus, andCaranxpapuensis;CaliguskapuhilionChaetodonaurigaandChaetodonlunula;CaliguslaticaudusonRhinecanthusaculeatus,Pseudobalistesflavimarginatus,M.flavolineatus,Upeneustaeniopterus,Chrysipteraglauca, andEpinephalusmerra;CaligusmutabilisonLutjanusfulvusandLutjanusmonostigma;CaligusrandallionC.ignobilis;Caligussp. onL.fulvus;CaritusserratusonChanoschanos;LepeophtheiruslewisionA.xanthopterus;LepeophtheirusuluusonC.ignobilis;DissonussimilisonArothronhispidus;Nemesissp. onCarcharhinusmelanopterus;HatschekialongiabdominalisonA.hispidus;HatschekiabicaudataonChaetodonaurigaandChaetodonlunula;KroyerialongicaudaonC.melanopterusandLernanthropussp. onKyphosuscinerascens. All copepod species reported here have been previously reported from the Indo-Pacific but represent new geographical records for Palmyra, demonstrating large-scale parasite dispersion strategies.

“…This study is part of a larger project to understand the structure and function of the Palmyra Atoll’s food webs. This paper is a companion to three others examining different fish parasite taxa (Vidal-Martínez et al 2012, 2017; Soler-Jiménez et al 2019) from Palmyra’s lagoon flats. As such, our survey adds to the few published, detailed species descriptions or host records from this Central Indo-Pacific region (Palm and Bray 2014).…”

Here, we present the results of a taxonomic survey of the nematodes parasitizing fishes from the lagoon flats of Palmyra Atoll, Eastern Indo-Pacific. We performed quantitative parasitological surveys of 653 individual fish from each of the 44 species using the intertidal sand flats that border the atoll’s lagoon. We provide morphological descriptions, prevalence, and mean intensities of the recovered seven species of adult nematode (Pulchrascaris chiloscyllii, Capillariidae gen. sp., Cucullanus bourdini, Cucullanus oceaniensis, Pseudascarophis sp., Spinitectus (Paraspinitectus) palmyraensissp. nov., Philometra pellucida) and three larval stages (Pulchrascaris sp., Hysterothylacium sp., Cucullanus sp.). We recorded: Pulchrascaris chiloscyllii from Carcharhinus melanopterus; Capillariidae gen. sp. from Chaetodon lunula, Lutjanus fulvus, and Ellochelon vaigiensis; Cucullanus bourdini from Arothron hispidus; Cucullanus oceaniensis from Abudefduf sordidus; Pseudascarophis sp. from Chaetodon auriga, Chaetodon lunula, and Mulloidichthys flavolineatus; Spinitectus (Paraspinitectus) palmyraensissp. nov. from Albula glossodonta; Philometra pellucida from Arothron hispidus; and three larval forms, Pulchrascaris sp. from Acanthurus triostegus, Acanthurus xanthopterus, Rhinecanthus aculeatus, Platybelone argalus, Carangoides ferdau, Carangoides orthogrammus, Caranx ignobilis, Caranx melampygus, Caranx papuensis, Chaetodon auriga, Chanos chanos, Amblygobius phalaena, Asterropteryx semipunctata, Valencienea sexguttata, Kyphosus cinerascens, Lutjanus fulvus, Lutjanus monostigma, Ellochelon vaigiensis, Mulloidichthys flavolineatus, Upeneus taeniopterus, Gymnothorax pictus, Abudefduf septemfasciatus, Abudefduf sordidus, and Stegastes nigricans; Hysterothylacium sp. type MD from Acanthurus triostegus, Carangoides ferdau, Chaetodon lunula, Chanos chanos, Kyphosus cinerascens, Abudefduf sordidus, and Arothron hispidus; and Cucullanus sp. from Caranx ignobilis. Spinitectus (Paraspinitectus) palmyraensissp. nov. (Cystidicolidae) is described from the intestine of roundjaw bonefish Albula glossodonta. All the nematode species reported in this study represent new geographical records. We discuss how our survey findings compare to other areas of the Indo-Pacific, and the way the relatively numerical dominance of trophically transmitted larval stages likely reflect the intact food web of Palmyra Atoll, which includes a large biomass of large-bodied top predator sharks and ray-finned fishes.

“…Its location on a fast-spreading plate boundary that experiences large-scale eruptive disturbance every 10-20 years [35] allows us to examine how features of parasite species richness and composition differ in an island-like and disturbed environment. We compare our data to coastal marine benthic ecosystems that differ in their degree of disturbance and isolation, and for which parasitological data were collected using similar methods: kelp forests on the coast of Santa Barbara, California, USA [51] and the lagoon sandflat of Palmyra Atoll in the Line Islands Archipelago [52][53][54][55][56].…”

Parasite diversity at isolated, disturbed hydrothermal vents

Habitat isolation and disturbance are important regulators of biodiversity, yet it remains unclear how these environmental features drive differences in parasite diversity between ecosystems. We test whether the biological communities in an isolated, frequently disturbed marine ecosystem (deep-sea hydrothermal vents) have reduced parasite richness and relatively fewer parasite species with indirect life cycles (ILCs) compared to ecosystems that are less isolated and less disturbed. We surveyed the parasite fauna of the biological community at the 9°50′N hydrothermal vent field on the East Pacific Rise and compared it to similar datasets from a well-connected and moderately disturbed ecosystem (kelp forest) and an isolated and undisturbed ecosystem (atoll sandflat). Parasite richness within host species did not differ significantly between ecosystems, yet total parasite richness in the vent community was much lower due to the low number of predatory fish species. Contrary to expectation, the proportion of ILC parasite species was not lower at vents due to a high richness of trematodes, while other ILC parasite taxa were scarce (nematodes) or absent (cestodes). These results demonstrate the success of diverse parasite taxa in an extreme environment and reinforce the importance of host diversity and food web complexity in governing parasite diversity.
