Redescription of Oulactis concinnata (Drayton in Dana, 1846) (Cnidaria: Anthozoa: Actiniidae), an actiniid sea anemone from Chile and Perú with special fighting tentacles; with a preliminary revision of the genera with a “frond-like” marginal ruff
Provedor de dados: 16
Autores: Häussermann, V.
Two species of sea anemones with a conspicuous marginal ruff of frond-like structures encompassing the tentacular crown occur on the Chilean coast. Oulactis concinnata (= Isoulactis chilensis) (Drayton in Dana, 1846) is re-described in detail and further information is provided for Oulactis coliumensis (Riemann- Zürneck &amp; Gallardo, 1990) (= Saccactis coliumensis) (both Actiniidae). The distribution of O. concinnata from Playa Las Salinas, Perú (9°19’10’’S, 78°26’30’’W), to the region of Valdivia, Chile (39°47’S, 73°21’W), lies within a zoogeographical unit known as the Peruvian Province. Re-description of O. concinnata is based on examination of 10 specimens collected between 1975 and 2003, and on observations of about 50 living anemones in their...

Marine Gastrotricha and Kinorhyncha from Scheveningen
Provedor de dados: 16
Autores: Zaneveld, J.S.
In the first three months of 1937 some Gastrotricha and Kinorhyncha were collected by the author at the beach of Scheveningen. Up to the present no members of these classes were recorded from this part of the North Sea, and moreover, they are all new for the fauna of the Netherlands. Therefore I summarized the results of the examination in the present paper. During neap tide some sand of the beach was put into glassjars, which were beforehand partially filled with sea water. The sand was taken from the surface of the beach, as near to the water line as possible. As described by Remane (1936, pp. 234—235) the glassjars were put in a quiet spot without aeration for 1—2 weeks. After this time every day a proof was taken with a pipette from the surface of the...

Corymorpha tomoensis Ikeda, 1910 (Cnidaria, Hydrozoa): first record of a corymorphid hydropolyp from Indonesian waters and a review of the species of Corymorpha M. Sars, 1835
Provedor de dados: 16
Autores: Vervoort, W.
A description is given of a corymorphid polyp, Corymorpha tomoensis Ikeda, 1910, collected during an expedition of the National Museum of Natural History, Leiden, The Netherlands, to the Indonesian island of Ambon. This is the first record of a polyp of the genus Corymorpha M. Sars, 1835 from Indonesian waters; corymorphid medusae were collected during the Siboga Expedition and described by Maas (1905) as Euphysora bigelowi; the polyp of that species was subsequently reared in the laboratory (Sassaman &amp; Rees, 1978) and identified as a species of Corymorpha. Species now classified in Corymorpha M. Sars, 1835 are briefly reviewed and their status and distribution discussed.

New Scleractinian corals (Cnidaria: Anthozoa) from Sabah, North Borneo. Description of one new genus and eight new species, with notes on their taxonomy and ecology
Provedor de dados: 16
Autores: Ditlev, H.
Eight new species and one new genus of Scleractinian corals from Darvel Bay, North-western Borneo are described and illustrated. Enigmopora darveliensis, Acropora ridzwani, Lithophyllon ranjiti, Pectinia crassa, Mycedium spina, Plerogyra multilobata, Plerogyra diabolotus, and Plerogyra cauliformis. The evolutionary and distributional significance of the species is discussed. Borneo’s unique equatorial location and stable geological history are held responsible for its high diversity of corals with a number of unique species. The morphology of Enigmopora darveliensis is discussed and compared to other supposedly primitive extant corals. The endemic status of most of the Plerogyra species, with their unusually large polyps, is due to their narrow ecological...

Provedor de dados: 16
Autores: Morandini, A.C.; Jarms, G.
Within the order Coronatae, six valid species remain known only by their polyp stage. The inability to relate them to any medusae genera of the group is a problem that remains to be solved in the order. With the examination of type specimens, we reassign the species Stephanoscyphistoma sibogae and S. striatus to the genera Atorella and Nausithoe respectively.

Notes on taxonomy and taphonomy of two Upper Maastrichtian (Upper Cretaceous) scleractinian corals from Limburg, The Netherlands
Provedor de dados: 16
Autores: Leloux, J.
A lectotype has been assigned for Placosmilia? robusta Umbgrove, 1925. This taxon, although fitting into the original diagnosis of Placosmilia, is not defined by the emended diagnosis of Alloiteau and later authors. Specimens from the Upper Maastrichtian of The Netherlands, that were formerly wrongly attributed to Galaxea fasciculata (Lamarck, 1816), a homonym of the extant species Galaxea fascicularis (Linnaeus, 1758), belong to Placocoenia macrophthalma (Goldfuss, 1826). The specimen depicted as P. macrophthalma by Umbgrove does not belong to this taxon and is placed in open nomenclature.

Provedor de dados: 16
Autores: Horita, T.
Lobatolampea tetragona gen. nov. &amp; spec. nov. was collected from coastal waters of Ise Bay, near Toba, Pacific coast of middle Japan. It assumes a medusoid bell-shape when floating, but is nearly discshaped when resting on the bottom. It is characterized by four C-shaped gonads present on the distal part of the subpharyngeal meridional canals, beyond the oral end of the comb rows. “Primitive” oral lobes are also formed and ctenes are found at the site of the presumptive auricles. The morphology of this species differs from any previously described larval or adult form, and is intermediate between the orders Cydippida and Lobata. The larvae are of the cydippid type.

Autores: Fedorowski, J.
Rugose corals reinvestigated herein constitute the main part of the collection described by de Groot (1963). The taxonomy proposed herein differs in several instances from that accepted originally by de Groot. Some changes, such as Petalaxis for Lithostrotionella and Calophyllum instead of Polycoelia, were already introduced in de Groot’s unpublished catalogue. Others were introduced in order to match the recent advances in rugose coral systematics. Most systematic changes were based on new microstructural, diagenetic and hystero-ontogenetic studies. These are described in detail for individual species and briefly discussed in the concluding considerations. Trabecular microstructure of septa and its diagenetic alteration was documented for most species....

Reinterpretation of some tentacular structures in actinodendronid and thalassianthid sea anemones (Cnidaria: Actiniaria)
Provedor de dados: 16
Autores: Ardelean, A.
The oral disc of an actinodendronid sea anemone is drawn out into a variable number of highly branched tentacular structures that make the anemone resemble a tree. These tentacular structures have been considered either lobes or branched tentacles. The term lobe has been applied to various structures of the oral disc in sea anemones; I distinguish between temporary lobes, permanent marginal lobes, and permanent tentacular lobes. I use the number of mesenterial pairs involved in a tentacular structure as evidence that tentacular structures in Actinodendronidae should be considered tentacles, not lobes. According to this interpretation, actinodendronids have only one tentacle communicating with each intermesenterial space, both endocoels and exocoels. The...

The reproductive system and the spermatozoon of Megadasys sterreri from Lanzarote (Canary Islands, Spain) were studied at structural and ultrastructural levels. The species is a simultaneous hermaphrodite with cross-fertilization and shows paired gonads, the male anterior and the female posterior, and both gametes mature in a caudo-cephalic direction. Sperm ducts converge on the midline and open into a ventral common pore. Two sexual accessory organs are present in the caudal trunk. A pipe-like frontal organ lies between the ovaries and the caudal organ, and is composed of a long, thin region connected to a large zone containing mature and degenerating spermatozoa. The cigar-like caudal organ is elongate, bulky and is made of an anterior glandulo-muscular...

Biodiversity on the marginal coral reefs of South Africa: What does the future hold?
Provedor de dados: 16
Autores: Schleyer, M.H.; Celliers, L.
Southern African coral communities form a continuum from the more typical, accretive reefs in the tropics of Mozambique to the marginal, southernmost African distribution of this fauna in KwaZulu- Natal. While the latter are limited in size, they are gaining increasing attention as they provide a model for the study of many of the stresses to which these valuable systems are globally being subjected. Soft coral cover, comprising relatively few species, exceeds that of scleractinians over much of the southern reefs, and the coral communities attain a high biodiversity at this latitude on the East African coast. A long-term monitoring programme has revealed small yet significant changes in community structure on the reefs in recent years, concurrent with...

Provedor de dados: 16
Autores: Marques, A.C.; Mergner, H.; Höinghaus, R.; Santos, C.M.D.; Vervoort, W.
The morphology of 25 species of the family Eudendriidae was studied, with special regard to their reproductive organs, using techniques of SEM and optical microscopy. Whenever possible a re-analysis of the diagnostic characters of these species was carried out. Furthermore, several synonymies were confirmed or discussed and remarks on taxonomical details are presented. A developmental (ontogenetical) series is proposed for the reproductive differentiation, and its usefulness for phylogenetic analysis is considered.

The hydroid fauna of Tasmanian seamounts
Provedor de dados: 16
Autores: Watson, J.E.; Vervoort, W.
Seventy seamounts 50 to 100 km off South East Cape, southern Tasmania, rise from depths of 1000- 2000 m on the Australian continental slope. Sampling of the slopes of 14 seamounts was undertaken in 1997 by the Australian Commonwealth Scientific &amp; Industrial Research Organisation (CSIRO). The collection yielded 14 species of hydroids, six of which are new, including two species of a new genus. Only Halecium fragile Hodgson, 1950, and Tripoma arboreum Hirohito, 1995, have previously been recorded from Tasmania. Other species are known from deep water off New Zealand, Japan and the south-western Atlantic.

The Free Living Nematodes of the Mediterranean II. The Camargue
Provedor de dados: 16
Autores: Schuurmans-Stekhoven Jr., J.H.
In 1933 Dr. G. J. van Oordt together with a number of biological students made an excursion to the Camargue. During that trip he collected some samples of mud from brackish ponds and pools in the Rhône Delta, which collection he entrusted me for further research. At this place I will bring him my renewed thanks for his contribution to nematology. Although the collection was not great, it brought to light some interesting new species. Moreover it allows us to say something about the penetration of marine forms into brackish waters. A comparison of the list of forms given below with the lists I have given from Nematodes found to occur in the former Zuidersea shows that the penetration of marine forms into brackish waters in the Mediterranean is performed in...

A new species of Allopathes (Cnidaria: Antipatharia) from the eastern Atlantic
Provedor de dados: 16
Autores: Opresko, D.M.
A new species of antipatharian coral, Allopathes denhartogi, is described from the eastern Atlantic. The species is distinguished from the two other species in the genus by spines that are larger, less dense and not arranged in verticils. Furthermore, the colony appears to reach a smaller size and has relatively fewer ramifications compared to the other species.

Autores: Gittenberger, A.
This is the first record of an association between a wentletrap species (Gastropoda: Epitoniidae) and coral species of the Euphyllidae (Scleractinia), i.e. Plerogyra simplex and P. diabolotus. While describing Epitonium hartogi spec. nov., special attention is given to the ontogenetic development within the eggcapsules, the structure and microsculpture of the opercula, the radulae, and the microsculpture on the radular jaws. These characters proved to be at least partly diagnostic in the epitoniid species Epitonium albidum, E. billeeanum, E. costulatum, E. hoeksemai, E. ingridae, E. lochi, E. millecostatum, E. pyramidalis, E. twilae, E. ulu and Nitidiscala tincta.

Locomotory behaviour and functional morphology of Nematostella vectensis (Anthozoa: Actiniaria: Edwardsiidae): a contribution to a comparative study of burrowing behaviour in athenarian sea anemones
Provedor de dados: 16
Autores: Williams, R.B.
The locomotory behaviour and functional morphology of English populations of a small (&lt;2 cm long), burrowing athenarian sea anemone, Nematostella vectensis Stephenson, 1935 (= N. pellucida Crowell, 1946), which lives in soft mud in salt marshes and creeks, are described. Objectives were to ascertain the specific stimuli and environmental conditions determining when and how locomotion is employed, and to assess survival values. Experimentation and anatomical examination revealed how anemones move, and their functional morphology was interpreted in a physiological context. Finally, locomotion, morphology and habitat were compared for several athenarian anemones, to ascertain what correlations there are, if any. Essential environmental conditions for N....

Columactinastraea anthonii sp. nov. (Scleractinia, Astrocoeniina), a new coral species from the Maastrichtian (Upper Cretaceous) of The Netherlands
Provedor de dados: 16
Autores: Leloux, J.
Only four cerioid species of scleractinian corals have been described from the Maastrichtian in its type area; the montlivaltiid Isastrea angulosa (Goldfuss, 1826), and the astrocoeniids Actinastrea goldfussi d’Orbigny, 1849, A. faujasi (Quenstedt, 1881) and Columastrea fallax Umbgrove, 1925. A lectotype is selected for the latter species. A new cerioid species, Columactinastraea anthonii sp. nov., is recorded from the middle part of the Meerssen Member (Maastricht Formation) at the ENCI Quarry, Zuid Limburg, The Netherlands. It is well-preserved and differs from other Columactinastraea species mainly by the relatively large diameter of its lumen.

New records on sea anemones (Anthozoa: Actiniaria) from hydrothermal vents and cold seeps
Provedor de dados: 16
Autores: López-González, P.J.; Rodríguez, E.; Gili, J.-M.; Segonzac, M.
During several cruises carried out by the Ifremer (Institut français de recherche pour l’exploitation de la mer) with the submersile “Nautile” at different hydrothermal sites and cold seeps, an important collection of anthozoans - mainly actiniarians - was sampled. Additional material was collected by an American cruise with the submersile “Alvin”. The goal of the present contribution is to describe part of this actiniarian fauna inhabiting three chemoautotrophic sites, one of them in the Mid-Atlantic Rise and the other two in the Eastern Pacific. A new genus and species of actinostolids is proposed after the study of specimens collected at hydrothermal vents in the Guaymas Basin (East Pacific Rise, Gulf of California, 27º00’N-111º24’W, 2020 m)....

Cantellius cardenae spec. nov. (Cirripedia: Pyrgomatinae) from Acropora (Isopora) brueggemanni (Brook, 1893) (Anthozoa: Acroporidae), a case of host specificity in a generalist genus
Provedor de dados: 16
Autores: Achituv, Y.; Hoeksema, B.W.
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.

Priapulus from the deep sea (Vermes, Priapulida)
Provedor de dados: 16
Autores: Land, J. van der.
INTRODUCTION The species of the genus Priapulus occur in rather cold water. Hence, their shallow-water distribution is restricted to northern and southern waters (fig. 1); there are only a few isolated records from sub-tropical localities. However, in deep water the genus apparently has a world-wide distribution (fig. 2). The northern species (P. caudatus De Lamarck) and the southern species (P. tuberculatospinosus Baird) from shallow water are well defined but the specimens from the deep sea present systematical problems. In my survey of the Priapulida (Van der Land, 1970) I could not answer the question of their identity, because I had seen only very few specimens from deep water and not a single one from the tropical deep sea. Meanwhile I could study...

Macrozooplankton diversity: how much do we really know?
Provedor de dados: 16
Autores: Pierrot-Bults, A.C.; Spoel, S. van der.
Pelagic species are widely distributed in a horizontal plane and have three-dimensional distributions, since the sea covers about 70% of the surface of the earth, and on average 4 km deep. For most macrozooplankton and micronekton groups there seems to be no great expectations of finding new taxa with the exception of gelatinous groups and of the deep sea, which is a relatively unknown especially in the benthopelagic zone close to the sea-bed. However, we do not know very much about variation, either morphological or genetical, within socalled species in different parts of their range. We think we are dealing with single very broadly distributed species, which, in reality, are species complexes consisting of several more or less cryptic species or...

The phylogenetic relationships of the scleractinian genus Psammocora with the other genera traditionally included in the family Siderastreidae and some Fungiidae are assessed based on combined skeletal and molecular data. P. explanulata differs from the other examined congeneric species (P. contigua, P. digitata, P. nierstraszi, P. profundacella, P. superficialis, and P. stellata) in possessing interstomatous septa between adult corallites, costae, and in having continuous buttress-like structures joining septal faces (i.e., fulturae) which typically occur in fungiids. These characters are shared with Coscinaraea wellsi but not with the remainder of the examined siderastreids (the congeneric C. columna, and Anomastraea irregularis, Horastrea indica,...

Autores: Gittenberger, A.; Hoeksema, B.W.
On a patch reef off Makassar, Sulawesi, Indonesia, corals identified as Fungia (Cycloseris) costulata, Fungia (Cycloseris) tenuis and Fungia (Cycloseris) cf costulata were collected down to a maximum depth of 10 m. The corals lived sympatrically. Mushroom coral clones resulting from fragmentation can be recognized by their equal coloration and close proximity. Therefore, to ensure that no clones were collected, corals of dissimilar colors were selected at a mutual distance of 5 m. The corals were kept alive in two 30 liter sea-water aquariums with an air-pump. They were photographed in detail. Using allozyme electrophoresis in a laboratory close to the field area, it was tested whether the separate coral morphs should be considered three species....

The anatomy, terminology, and homology of acrorhagi and pseudoacrorhagi in sea anemones
Provedor de dados: 16
Autores: Daly, M.
The morphology of the column margin is an especially important feature in the taxonomy and biology of members of the sea anemone family Actiniidae. Despite the importance of marginal structures, their anatomy and the terminology describing them is poorly delimited. Consequently, homologies of the components of the marginal structures are poorly understood and taxonomies that depend on the presence, absence, or particular manifestation of marginal structures are confused. I review and synthesize anatomical descriptions of the marginal structures and find that they consist of two parts: a projection of the column and a holotrich-dense pad (= acrorhagus) that is histologically differentiated from the surrounding tissues. Although acrorhagi are functionally...

The zoanthid genus Sphenopus (Cnidaria: Anthozoa: Zoantharia), like many other brachycnemic zoanthids, is found in shallow subtropical and tropical waters, but is uniquely unitary (solitary, monostomatous), azooxanthellate, and free-living. With sparse knowledge of its phylogenetic position, this study examines the phylogenetic position of Sphenopus within the family Sphenopidae utilizing specimens from southern Taiwan and Brunei collected in 1999-2011, and furthermore analyzes the evolution of its unique character set via ancestral state reconstruction analyses. Phylogenetic analyses surprisingly show Sphenopus to be phylogenetically positioned within the genus Palythoa, which is colonial (polystomatous), zooxanthellate, and attached to solid substrate....

Three new species belonging to the genera Anthelia, Cespitularia and Ovabunda are illustrated. In addition, a new genus belonging to the family Xeniidae is introduced accompanied by scanning electron micrographs of its sclerites. Gross morphology and the ultra-structure of the sclerites indicate there are some similarities in this new genus with Anthelia. However,...

An unusual sea anemone from slope depths of the tropical west Pacific: range extension and redescription of Isactinernus quadrilobatus Carlgren, 1918 (Cnidaria: Actiniaria: Actinernidae)
Provedor de dados: 16
Autores: Fautin, D.G.; Hartog, J.C. den.
The sea anemone species Isactinernus quadrilobatus Carlgren, 1918, and Synactinernus flavus Carlgren, 1918, which were described in new monotypic genera from few specimens collected in southern Japan, are synonymized, based on many more specimens from the South Pacific. As well as the geographic range, the depth range of this species has been extended to 110-700 m. The species had been distinguished primarily on whether the oral disc had four lobes (I. quadrilobatus) or eight (Synactinernus flavus) – we conclude their number is largely related to size of the animal. Other features that Carlgren had used to differentiate the genera (and species) are inconsistently present and do not correlate with lobe number.

A survey of the genera Sarcodictyon Forbes, 1847, and Rolandia Lacaze-Duthiers, 1900, (Anthozoa: Octocorallia) in the North-eastern Atlantic and the Mediterranean
Provedor de dados: 16
Autores: Ocaña, O.; López-González, P.J.; Núñez, J.; García-Gómez, J.C.
Sarcodictyon catenatum Forbes, 1847, is a common species in the Atlantic and the Mediterranean. However, often it has been mistaken for Rolandia coralloides Lacaze-Duthiers, 1900. On the basis of British and Mediterranean material we studied the main characters for distinguishing S. catenatum. We consider Rolandia coralloides Lacaze-Duthiers, 1900, to be a valid species and we assign to it all the material named Rolandia rosea by S. Weinberg (1978). Furthermore, a histological study confirmed that R. coralloides typically forms groups of polyps embedded in a common coenenchyme. Therefore, the possibility of transferring R. coralloides from Stolonifera to Alcyonacea is discussed. Evagorgia rosea Philippi, 1842, is here considered to be a nomen dubium.

Control of bleaching in mushroom coral populations (Scleractinia: Fungiidae) in the Java Sea: stress tolerance and interference by life history strategy
Provedor de dados: 16
Autores: Hoeksema, B.W.
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...

On the classification of Corallimorphus (Anthozoa: Corallimorpharia): the ratio of discal and marginal tentacles
Provedor de dados: 16
Autores: Hartog, J.C. den; Grebelnyi, S.D.
Since the study of the genus Corallimorphus was started, the main taxonomic character used to separate species has been the ratio of the number of marginal tentacles to that of the discal ones. Polyps with a marginal:discal (m:d) tentacle ratio of 2:1 and 4:1 collected by the “Challenger” expedition were described as two distinct species, Corallimorphus rigidus and Corallimorphus profundus respectively (Moseley, 1877a, 1877b; Hertwig, 1882, 1888). This feature remained important in the taxonomy of the genus. For example, Fautin et al. (2002) subdivided the genus Corallimorphus into two groups of species: Corallimorphus rigidus, C. ingens, C. atlanticus, C. denhartogi (ratio of marginal: discal tentacles 2:1) were referred to the «rigidus» group.

Autores: Renema, W.
Species of Planorbulinella are common in several southern European Neogene sections, as well as on recent reefs in the Indo-West Pacific. So far, they have only been recorded rarely from the Neogene of the Indo-West Pacific region. The only published records are from the Early Miocene of Papua New Guinea and New Zealand. Two new species, a new record of a known species and an as yet undescribed species from the Neogene of Indonesia are reported herein. This increases the number of known Planorbulinella species from Indonesia to at least five.

Corallimorphus profundus in shallow Antarctic habitats: Bionomics, histology, and systematics (Cnidaria: Hexacorallia)
Provedor de dados: 16
Autores: Riemann-Zürneck, K.; Iken, K.
In March 2000 and November/December 2001 thirteen specimens of Corallimorphus profundus Moseley, 1877, a conspicuous, anemone-like cnidarian, were hand-sampled by SCUBA diving in 30 to 40 m depth off US Palmer Station, Antarctic Peninsula. Corallimorphus species were formerly recorded only from deep water habitats from where they had been brought up more or less damaged, with most of their epithelia lost or macerated. The present well preserved specimens offer the opportunity to study various aspects of the species’ morphology and biology, particularly as one mature female contained a full cycle of oogenesis besides two batches of brooded developmental stages. Most of the results obtained demonstrate that the genus Corallimorphus shows features and...

Lohowia koosi, a new species and new genus in the family Alcyoniidae, is described from Lord Howe Island, Australia. The new taxon has dimorphic polyps and a similar morphology to some of the flat, lobe-less nominal species of Lobophytum. The new taxon is clearly distinguished, however, by the possession of large, heavily armed autozooids, polypary surface sclerites in the form of large spindles that protrude through the surface, extremely large interior sclerites and base surface sclerites in the form of rods, spindles and ovals.

The mushroom coral fauna (Scleractinia: Fungiidae) of Brunei Darussalam (South China Sea) and its relation to the Coral Triangle
Provedor de dados: 16
Autores: Hoeksema, B.W.; Lane, D.J.W.
Brunei Darussalam is situated on the northwest coast of Borneo, just outside the westernmost boundary of the area presently recognised as the centre of maximum marine biodiversity, the so-called Coral Triangle. This diversity is particularly quantified with regard to numbers of reef coral species. Most coral reefs of Brunei are offshore, submerged patch reefs, which makes them hard to discern from the water surface. Few coral studies have been carried out here, although recently an extensive reef coral inventory has been published for Brunei. The present study builds on this inventory by presenting a focus on the mushroom coral fauna of Brunei, based on a survey of the family Fungiidae at 17 sites varying in distance offshore. The purpose of this study is...

Zoantharia (Cnidaria: Anthozoa: Hexacorallia) of the South China Sea and Gulf of Thailand: a species list based on past reports and new photographic records
Provedor de dados: 16
Autores: Reimer, J.D.; Wee, H.B.; Put, A.; Hoeksema, B.W.
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....

Provedor de dados: 16
Autores: Robson, E.A.
Precursor stages of large holotrichs in the mesenterial filaments of Corynactis californica and C.viridis have been visualised by simple methods using stained whole-mount preparations. Samples were taken from mesenterial filaments emitted during aggressive behaviour (which is reported for the first time in C. viridis). Results suggest that in natural conditions localised stimuli may provoke discharge along short stretches of mesenterial filament, followed by localised recruitment within these depleted areas.

Larger foraminifera on reefs around Bali (Indonesia)
Provedor de dados: 16
Autores: Renema, W.
The larger benthic foraminifera fauna from four regions at or near Bali are described. In 132 samples in total 19 species were found. This is a similar to species richness in areas like the Spermonde and Cebu, but the fauna composition differed markedly. For each species the occurrence at Bali and environmental parameters affecting this distribution are discussed. It is argued that the very low abundance of imperforate species is not due to the absence of their microhabitat, but due to climatic or oceanographic parameters. The most likely is the presence of periodic upwelling, which causes the seawater temperature to drop to low levels seasonally.

Actiniid sea anemones possess few characteristics of taxonomic value, which makes columnar outgrowths one of the most important features for systematic work. There are two species of actiniid sea anemones known from Chile and southern Peru that exhibit a column densely covered with non-adhesive vesicles: Phymactis papillosa (Lesson, 1830) (= Phymactis clematis) and Phymanthea pluvia (Drayton in Dana, 1846). Hereby both are re-described in detail. The re-descriptions are based on observations of about 100 living animals in their habitat and in aquaria and on the examination of 21 specimens of P. papillosa and seven specimens of P. pluvia collected in Chile between 1995 and 2003. In Chile, specimens of both species occur in tide-pools, on vertical and...

Larger benthic foraminifera and their distribution patterns on the Spermonde shelf, South Sulawesi
Provedor de dados: 16
Autores: Renema, W.; Hoeksema, B.W.; Hinte, J.E. van.
A systematic description of the distributional pattern of 20 species of larger benthic foraminifera on the Spermonde Archipelago and their relation with environmental parameters is presented. Around 13 islands transects at the exposed and leeward slope were sampled. Apart from parameters like substrate type, hydrodynamic energy and light intensity (directly related to depth) also nutrient availability and environmental stabiltity determine the distribution over the shelf. Some of the species, and especially the calcarinids, are less specialised to some of these parameters than in other areas. Elphidium craticulatum, showing chloroplast husbandry, is an important fauna component.
