The phylogenetic relationships of the Fungiidae, a family of predominantly free-living, zooxanthellate, reef corals, were studied by sequencing a part of the mitochondrial Cytochrome Oxidase I (COI) and the complete ribosomal Internal Transcribed Spacers (ITS) I & II of specimens from various locations in the Indo- West Pacific. Some sequences were retrieved by using fungiidspecific primers on DNA-extracts from parasitic gastropods living with these corals. The analyses were performed both including and excluding intraspecific variation to investigate the potential effect of saturation. Even though the present molecular phylogeny reconstructions largely reflect those based on morphological characters, there are some distinct differences. Three major...

In eerdere afleveringen van de serie 'Met Naturalis in zee' is verslag gedaan over een expeditie naar Bali, die in 2001 door Naturalis werd gehouden. In oktober 2003 ging het zeeteam van Naturalis naar Oost-Kalimantan voor nieuwe verkenningen. Deze expeditie maakte deel uit van een groot Indonesisch-Nederlands programma, waarin onderzoekers van diverse instituten participeerden. Dit artikel is het eerste in een reeks over allerlei aspecten van het onderwaterleven van het Berau gebied. Een gebied dat niet alleen interessant is voor onderzoek, maar ook geschikt voor een avontuurlijke vakantiereis.

Brandgevaar onder water

De vorige aflevering van 'Met Naturalis in zee' (Onderwatersport januari/februari 2004) ging over fel gekleurde hydroied-koralen. In dit verhaal wordt de aandacht gevestigd op minder kleurrijke varianten, die als bijzonderheid hebben dat ze gemeen kunnen steken. Vandaar de Nederlandse naam brandkoraal.

A new species of coral inhabiting barnacle Cantellius cardenae spec. nov. (Crustacea, Cirripedia: Pyrgomatinae) is described. This barnacle was found on the staghorn coral Acropora (Isopora) brueggemanni (Scleractinia: Acroporidae). It is characterized by having transversally elongated scuta and narrow terga with a spur length more than half of the total tergal length. This species belongs to the secundus group of Cantellius, which includes barnacles with transversally elongated scuta, and which are limited to the Acroporidae. The distribution of C. cardenae supports the hypothesis that structurally specialized pyrgomatines occupy a more limited variety of hosts than do morphologicaly generalized ones.

Bleaching was studied in populations of phylogenetically closely related species (n = 21) of mushroom corals (Scleractinia: Fungiidae) around Pari Island (Java Sea) during a period of excessive seawater warming in 1983. The interspecific variation in the proportions of affected individuals was significant. Spatial variation in the degree of bleaching anlong fungiid assemblages depended much on relative species abundances. Mushroom corals In relatively stagnant water of lagoons and on the inner reef flat showed little bleaching. Many of the outer reef mushroom corals at ≤ 9 m depth were affected, but only a few at greater depths (≥15 m). In most affected fungiids, the bleached part was pale (associated with pigment loss) instead of white (assumedly caused...

Cryptic marine biota of the Raja Ampat island group : Preliminary results of the Raja Ampat Expedition (2007), Ekspedisi Widya Nusantara (E-Win) of the Indonesian Institute of Sciences (LIPI)

Hoeksema, B.W.; Meij, S.E.T. van der.

The Raja Ampat expedition in 2007 was organized by the National Museum of Natural History Naturalis in Leiden in cooperation with the Research Centre for Oceanography (RCO-LIPI, Jakarta) as part of Ekspedisi Widya Nusantara (E-Win expedition) of the Indonesian Institute of Sciences (LIPI). The research team consisted of scientists from Indonesia, the Netherlands, Palau and the United States. The Raja Ampat islands are located northwest of Bird’s Head' peninsula in Papua, Indonesia. This area has recently gained much media attention due to its high marine biodiversity and the recent discovery of several new species of corals and fish. The expedition was based at Kri Eco Resort of Papua Diving, on Kri Island. The expedition aimed to study cryptic biota,...

Decline of the Jakarta Bay molluscan fauna linked to human impact

Meij, S.E.T. van der; Moolenbeek, R.G.; Hoeksema, B.W..

In 1937/38 representative mollusc collections were made in Jakarta Bay (West Java, Indonesia). New data from here and the adjacent offshore Thousand Islands archipelago (Kepulauan Seribu) became available in 2005. Although collecting efforts and sampling methods differed, a comparison of the molluscan fauna of Jakarta Bay between 1937/38 and 2005 reveals a distinct deterioration. From 1937 to 2005, Jakarta Bay received increasing amounts of sewage from the greater Jakarta area, as well as increased sediment input from the deforested West Java hinterland. Predatory gastropods and numerous mollusc species associated with carbonate (reef) substrate have vanished from Jakarta Bay, among which many edible species.

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...

A phylogenetically based comparative analysis of onshore-offshore distribution patterns of mushroom coral species (Scleractinia: Fungiidae) was made to reconstruct an evolutionary scenario for differentiation in fungiid shelf habitats. This phyloecological study integrates data on fungiid distribution patterns along environmental gradients on the Spermonde Shelf, SW Sulawesi, with a recently published phylogeny reconstruction of the Fungiidae. A mushroom coral fauna of 34 species was used to compare their distributions by use of 50-m2 belt quadrats in transects (1) from the mainland to the shelf edge, (2) around reefs with regard to predominant wind directions, and (3) over bathymetrical reef zones. Species association ordinations were made for each of the...

The mytilid bivalve Fungiacava eilatensis Goreau, Goreau, Neumann & Yonge, 1968, previously mistakenly referred to as F. eilatensis Soot-Ryen, 1969, is reported for the first time from Indonesia. It lives as an obligate endosymbiont of mushroom corals, particulary Fungia spp., reef-dwelling corals restricted to the tropical Indo-Pacific. Notes are given on its association with different host species, its habitat, its biogeography, and its possible competition with endosymbiotic gastropods belonging to the genus Leptoconchus (Coralliophilidae).

Claereboudt, M.; Hoeksema, B.W..

Summary: A new Fungia species from the Bismarck Sea is described and its taxonomic position is discussed. INTRODUCTION The Fungiidae have an important place among Indo-Pacific scleractinian reef corals. Many nominal species have been described in this family, but only about 40 of them proved to be valid (Hoeksema, in prep.) which is roughly 10% of the total number of living Indo-Pacific reef coral species. Only a few of these species do not occur in the central part of the Indo-Pacific, or more specifically the Indo-Malayan Region. The new species has been collected by both authors from different locations in Papua New Guinea and Indonesia. In the most recent generic revision of the Fungiidae, the genera Fungia Lamarck, 1801 and Cycloseris Milne Edwards...

Snails of the genus Coralliophila (Muricidae: Coralliophilinae) are common corallivores in the Caribbean, feeding on a wide range of host species. In the present study, the morphological and genetic variation in C. galea and C. caribaea were studied in relation to their association with host coral species at Curaçao. Differences in shell shape among snails living on different hosts were quantified using geometric morphometric and phylogenetic relationships were studied using two mitochondrial markers (12S and COI). Based on these analyses, a new species, C. curacaoensis sp. nov., was found in association with the scleractinian coral Madracis auretenra. Both C. galea and C. caribaea showed host-specific differences in shell shape, size, and shell allometry...

Examination of about 60,000 scleractinian corals of the families Dendrophylliidae, Euphylliidae and Fungiidae for the presence of associated wentletrap snails (Gastropoda: Epitoniidae) revealed various ectoparasitic life history strategies. Twenty Indo-Pacific wentletrap species were found, which were either host-specific or generalist. Most species were associated with mushroom corals, especially free-living species belonging to the Fungiidae. Snails showed different preferences with regard to their position relative to mushroom corals, the host’s size and its substrate. No preferences for depth were found. Infestation rates of mushroom corals in multi-species assemblages were negatively correlated with coral densities, which indicates that epitoniid...

In 'Met Naturalis in zee' van mei 2004 komt brandgevaar onderwater aan de orde. Aanleiding is een onderzoek aan brandkoralen, in het Engels 'fire corals' genoemd. Duikers en snorkelaars leren deze Millepora koralen snel herkennen na onbedoeld contact met het koraaloppervlak. Uit kleine poriën in dat gladde opppervlak steken haarfijne tentakels die netelkapsels bevatten. Daar brandt iemand zich meestal geen tweede keer aan. Dat kan heel anders bij dieren die zo goed gecamoufleerd zijn en zo venijnig pijn doen, dat het slachtoffer zich vaak niet realiseert wat hem is overkomen en ook niet direct ziet wie de boosdoener is.
