    Evaluation of the ecological function of amphitoxin in the reef-dwelling sponge Callyspongia (Euplacella) biru (Haplosclerida: Callyspongiidae) at southwest Sulawesi, Indonesia (2005)

    Description: The ecological function of the secondary metabolite amphitoxin produced by Callyspongia (Euplacella) biru is evaluated by a forced confrontation with the free-living scleractinian coral Fungia fungites at different exposure times. Our major goal was to determine whether such a forced confrontation with a spatial com­petitor would cause a significant change in the concentration of amphitoxin in the sponge tissue, indicating a regulatory mechanism of amphitoxin production. Firstly, the concentrations of amphitoxin of sponge fragments submitted to forced confrontation with a mushroom coral did not differ between the exposure times. Secondly, all sponge fragments, including the controls had a consistently lower amphitoxin concentration during the course of the experiment than the natural variation. Thirdly, the concentration of amphitoxin varied substantially between specimens implying that other ecological factors besides spatial competition regulate the production of bioactive compounds of C. biru.

    When forms meet genes: revision of the scleractinian genera Micromussa and Homophyllia (Lobophylliidae) with a description of two new species and one new genus (2016)

    Description: The scleractinian family Lobophylliidae is undergoing a major taxonomic revision thanks to the combination of molecular and morphological data. In this study, we investigate the evolutionary relationships and the macro- and micromorphology of six nominal coral species belonging to two of the nine molecular clades of the Lobophylliidae, clades A and B, and of Symphyllia wilsoni, a lobophylliid species analyzed from a molecular point of view for the first time. Sequence data from mitochondrial DNA (COI and the intergenic spacer between COI and l-rRNA), and nuclear DNA (histone H3 and ITS region) are used to generate robust molecular phylogenies and a median-joining haplotype network. Molecular results are strongly in agreement with detailed observations of gross- and fine-scale morphology of skeletons, leading to the formal revision of the genera Micromussa and Homophyllia and the description of two newly discovered zooxanthellate shallow-water species, Micromussa pacifica sp. nov. Benzoni & Arrigoni and Micromussa indiana sp. nov. Benzoni & Arrigoni, and a new genus, Australophyllia gen. nov. Benzoni & Arrigoni. In particular, Acanthastrea lordhowensis and Montastraea multipunctata are moved into Micromussa, A. hillae is synonymized with A. bowerbanki and is transferred to Homophyllia, and a revised diagnosis for both genera is provided. Micromussa pacifica sp. nov. is described from the Gambier Islands with its distribution spanning New Caledonia and eastern Australia. Despite a superficial resemblance with Homophyllia australis, it has distinctive macroand micromorphological septal features. Micromussa indiana sp. nov., previously identified as M. amakusensis, is here described from the Gulf of Aden and the southern Red Sea as a distinct species that is genetically separated from M. amakusensis and is morphologically distinct from the latter due to its smaller corallite size and lower number of septa. Finally, molecular trees show that S. wilsoni is closely related, but molecularly separated from clades A and B, and, also based on a unique 388 Arrigoni et al. – Phylogeny of Micromussa and Homophyllia combination of corallite and sub-corallite characters, the species is moved into Australophyllia gen. nov. These findings confirm the need for using both genetic and morphological datasets for the ongoing taxonomic revision of scleractinian corals.

    Prey selection of corallivorous muricids at Koh Tao (Gulf of Thailand) four years after a major coral bleaching event (2016)
    In:  Contributions to Zoology (1875-9866) vol.85 (2016) nr.3 p.291

    Publication Date: 2016-08-23
    Description: Corallivorous Drupella (Muricidae) snails at Koh Tao are reported to have extended their range of prey species following a major coral bleaching event in 2010. Populations of their preferred Acropora prey had locally diminished in both size and abundance, and the snails had introduced free-living mushroom corals in their diet. Although the coral community largely recovered, the Drupella population grew and reached outbreak proportions. For this study, corallivorous muricids at Koh Tao were studied more intensively to examine their identities, distribution and prey choice four years after the bleaching event. Drupella rugosa was identified as the major outbreak species and occurred at densities 〉 3 m-2 in depth ranges of 2-5 and 5-8 m. The density of D. rugosa was related to the live coral cover, Acropora colony density, and depth. Resource selection ratios revealed that species of Acropora, Psammocora and Pavona corals were attacked more frequently than would be expected based on their availability. Strikingly, fungiid corals were now avoided as prey in the recovered coral community, despite them being part of the preferred diet directly after the bleaching. Although D. rugosa showed a clear prey preference, it appears to be plastic by changing with prey availability. The muricids Drupella margariticola and Morula spinosa occurred in much lower densities and were less often associated with corals. Snails of the opportunistic corallivore D. margariticola usually co-occurred in D. rugosa aggregations, although they also formed feeding aggregations by themselves. Whether M. spinosa generally associates with corals as a corallivore or a scavenger has yet to be determined. Molecular analyses did not reveal cryptic speciation among snails sampled from different coral hosts and also no geographic variation. The present study also showed that corallivory is more common among D. margariticola and M. spinosa than previously known.

    Zoantharia (Cnidaria: Anthozoa: Hexacorallia) of the South China Sea and Gulf of Thailand: a species list based on past reports and new photographic records (2015)
    In:  Various articles (0217-2445) vol.63 (2015) p.334
    Details
    Publication Date: 2015-09-14
    Description: This study is the first review of Zoantharia species in the South China Sea and Gulf of Thailand. In addition to past literature records, new field observations are added from previously unexamined countries and regions. In total 16 species are listed, 15 of which belong to suborder Brachycnemina, and only one to suborder Macrocnemina. Two species are undescribed. The lack of Macrocnemina species is not likely indicative of a low diversity of this suborder in the South China Sea and Gulf of Thailand, but instead of an absence of research below shallow subtidal depths. As the majority of the new records from this study were randomly compiled by researchers who are not experts of Zoantharia, specific surveys by experts are needed in these two marine regions. The present list should provide a solid basis for such future research.

    The scleractinian Agaricia undata as a new host for the coral-gall crab Opecarcinus hypostegus at Bonaire, southern Caribbean (2020)

    Publication Date: 2024-01-12
    Description: The Caribbean scleractinian reef coral Agaricia undata (Agariciidae) is recorded for the first time as a host of the coral-gall crab Opecarcinus hypostegus (Cryptochiridae). The identity of the crab was confirmed with the help of DNA barcoding. The association has been documented with photographs taken in situ at 25 m depth and in the laboratory. The predominantly mesophotic depth range of the host species suggests this association to be present also at greater depths. With this record, all seven Agaricia species are now listed as gall-crab hosts, together with the agariciid Helioseris cucullata. Within the phylogeny of Agariciidae, Helioseris is not closely related to Agaricia. Therefore, the association between Caribbean agariciids and their gall-crab symbionts may either have originated early in their shared evolutionary history or later as a result of host range expansion. New information on coral-associated fauna, such as what is presented here, leads to a better insight on the diversity, evolution, and ecology of coral reef biota, particularly in the Caribbean, where cryptochirids have rarely been studied.

    On the identity of broad-shelled mussels (Mollusca, Bivalvia, Mytilus) from the Dutch delta region (2011)
    In:  Contributions to Zoology vol. 80 no. 2, pp. 95-106
    Details
    Publication Date: 2024-01-20
    Description: Late Quaternary (Eemian) deposits of the Netherlands contain shells that resemble those of living Mytilus galloprovincialis. Similar broad-shelled mytilids also occur in estuaries of the southwestern Netherlands together with slender individuals typical of M. edulis. We sampled living mussels along a depth gradient in the Oosterschelde to a) investigate whether a relation exists between shell shape and depth, b) test if the broadshelled specimens might represent M. galloprovincialis (or a hybrid with M. edulis) and c) assess by inference if the Quaternary specimens might be attributed to M. galloprovincialis as well. In order to do so, we compared genetic (length polymorphism of Me 15/16, COIII sequences and AFLPs) and shellmorphological characteristics (juvenile L/W ratios and socalled Verduin parameters) of the same specimens. The obtained dataset indicates that all studied mussels from the Oosterschelde should be attributed to M. edulis, including those with broad shell outlines. No correlation of shell-morphology and depth-distribution was found. The worn and generally damaged state of the Eemian specimens precluded measurement of the Verduin parameters, while juvenile L/W ratios turned out not to be diagnostic. Therefore the shell characters examined in this study are insufficient to demonstrate the possible presence of M. galloprovincialis shells in Quaternary deposits of the Netherlands.

    Systematics and character evolution of capitate hydrozoans (2023)
    In:  Cladistics vol. 2023 no. 12567
    Details
    Publication Date: 2024-01-19
    Description: Capitate hydrozoans are a morphologically and ecologically diverse hydrozoan suborder, currently including about 200 species.Being grouped in two clades, Corynida and Zancleida, these hydrozoans still show a number of taxonomic uncertainties at the species,genus and family levels. Many Capitata species established symbiotic relationships with other benthic organisms, including bryozoans,other cnidarians, molluscs and poriferans, as well as with planktonic dinoflagellates for mixotrophic relationships and with bacteria forthiotrophic ectosymbioses. Our study aimed at providing an updated and comprehensive phylogeny reconstruction of the suborder, atmodelling the evolution of selected morphological and ecological characters, and at testing evolutionary relationships between the sym-biotic lifestyle and the other characters, by integrating taxonomic, ecological and evolutionary data. The phylogenetic hypotheses herepresented shed light on the evolutionary relationships within Capitata, with most families and genera being recovered as monophyletic.The genusZancleaand family Zancleidae, however, were divided into four divergent clades, requiring the establishment of the newgenusApatizancleaand the new combinations for species inZancleaandHalocorynegenera. The ancestral state reconstructionsrevealed that symbiosis arose multiple times in the evolutionary history of the Capitata, and that homoplasy is a common phenomenonin the group. Correlations were found between the evolution of symbiosis and morphological characters, such as the perisarc. Overall,our results highlighted that the use of genetic data and a complete knowledge of the life cycles are strongly needed to disentangle taxo-nomic and systematic issues in capitate hydrozoans. Finally, the colonization of tropical habitat appears to have influenced the evolu-tion of a symbiotic lifestyle, playing important roles in the evolution of the group.

    Biodiversity, ecology, and taxonomy of sediment-dwelling Dendrophylliidae (Anthozoa, Scleractinia) in the Gulf of Thailand (2023)
    Brill
    In:  Contributions to Zoology vol. 92 no. 5, pp. 468-509
    Details
    Publication Date: 2024-01-16
    Description: Dendrophylliidae represents one of the most speciose families of scleractinian coral, expressing a wide range of morphological and ecological traits. Recent phylogenetic analyses of the family have indicated that several conventional genera are in need of revision. In the Gulf of Thailand, dendrophylliids are predominantly found on hard-substrate reefs and pinnacles, or on soft-substrate habitats. Soft-substrate habitats in the Gulf of Thailand have been shown to host unique species assemblages and faunal ecology. Here we provided an updated phylogenetic hypothesis for the Dendrophylliidae based on newly sequenced species, and analyses integrating morphology, genetics and ecology. High-resolution Micro-ct was used to create digital versions of the studied species, allowing for non-destructive examination of internal and external features. Our findings allowed for a taxonomic assessment of the genera Heteropsammia and Tubastraea, with the species Balanophyllia (Eupsammia) stimpsonii, moved to the genus Tubastraea. They also support the polyphyly of Dendrophyllia and Cladopsammia. In-situ surveys provided population-density information for four dendrophylliid species from soft substrate habitats, indicating that the species Heteropsammia moretonensis may be the most widespread within the Gulf of Thailand. These surveys also provided novel ecological documentation associated with these corals, including protocooperative feeding upon a sea pen by Tubastraea stimpsonii comb. nov., and feeding upon other cnidarians by Heteropsammia spp.
