A new Agelas (Demospongiae: Agelasida: Agelasidae) from the Thousands Islands, West-Java, Indonesia Naturalis
Voogd, N.J. de; Parra-Velandia, F.J.; Soest, R.W.M. van.
Agelas linnaei spec.nov. (Porifera: Demospongiae: Agelasida: Agelasidae) is described from the Thousands Islands reef complex, West- Java, Indonesia. The new species is compared with all other Agelas species occurring in the Indo-West Pacific region. The new species differs from these other species by the overall morphology and the size of the verticillated acanthostyles. Surprisingly, this is only the second Agelas species ever described from Indonesia.

Amphimedon denhartogi spec. nov. (Porifera: Haplosclerida) from deep reef habitats in Indonesia Naturalis
Voogd, N.J. de.
A new sponge species Amphimedon denhartogi spec. nov., belonging to the family Niphatidae of the order Haplosclerida, is described from 3 localities in Indonesia: Tulamben (NE Bali), Siladen Island (NE Sulawesi) and Kambing Island (SW Sulawesi). Amphimedon denhartogi spec. nov. is characterised by its growth form of thinly flabellate branches, the occurrence of star-shaped oscules over one side of the sponge body, and by its small strongyles, and can hardly be confused with another species. All specimens were found in similar habitats, at around 40-45 m of depth on steep sandy slopes.

Biodiversity of shallow-water sponges (Porifera) in Singapore and description of a new species of Forcepia (Poecilosclerida: Coelosphaeridae) Naturalis
Lim, S.-C.; Voogd, N.J. de; Tan, K.-S..
A surprisingly high number of shallow water sponge species (197) were recorded from extensive sampling of natural intertidal and subtidal habitats in Singapore (Southeast Asia) from May 2003 to June 2010. This is in spite of a highly modified coastline that encompasses one of the world’s largest container ports as well as extensive oil refining and bunkering industries. A total of 99 intertidal species was recorded in this study. Of these, 53 species were recorded exclusively from the intertidal zone and only 45 species were found on both intertidal and subtidal habitats, suggesting that tropical intertidal and subtidal sponge assemblages are different and distinct. Furthermore, only a third of the fouling species of sponges from a previous study was...

Callyspongia (Euplacella) biru spec. nov. (Porifera: Demospongiae: Haplosclerida) from Indonesia Naturalis
Voogd, N.J. de.
A new sponge species Callyspongia (Euplacella) biru spec. nov. is described from various locations within Indonesia (NE Bali, SW & NE Sulawesi and NE Kalimantan). The species is assigned to the subgenus Euplacella of the genus Callyspongia because it has brushes of spicules on the nodes of its double-meshed ectosomal skeleton. The species is discussed and compared with relevant Callyspongia records from other Indonesian and neighbouring Indo-Pacific areas.

Evaluation of the ecological function of amphitoxin in the reef-dwelling sponge Callyspongia (Euplacella) biru (Haplosclerida: Callyspongiidae) at southwest Sulawesi, Indonesia Naturalis
Voogd, N.J. de; Haftka, J.J.H.; Hoeksema, B.W..
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...

Indonesian sponges of the genus Petrosia Vosmaer (Demospongiae: Haplosclerida) Naturalis
Voogd, N.J. de; Soest, R.W.M. van.
Sponges of the genus Petrosia (Demospongiae: Haplosclerida) are large and characteristic components of many Indonesian reefs. We identify and provide descriptions of seven species of Petrosia collected recently on SW Sulawesi reefs (Eastern Indonesia), two of which are new to science: Petrosia (Petrosia) alfiani spec. nov. and Petrosia (Petrosia) hoeksemai spec. nov. Additional species recorded are Petrosia (Petrosia) lignosa Wilson, 1925, Petrosia (Petrosia) nigricans Lindgren, 1897, Petrosia (Petrosia) plana Wilson, 1925, Petrosia (Strongylophora) corticata (Wilson, 1925) and Petrosia (Strongylophora) strongylata Thiele, 1903. The species are discussed and compared with Petrosia records from other Indonesian and neighbouring Indo-West Pacific areas. We...

Lock, stock and two different barrels: comparing the genetic composition of morphotypes of the Indo-Pacific sponge Xestospongia testudinaria Naturalis
Swierts, T.; Peijnenburg, K.T.C.A.; Leeuw, C. de; Cleary, D.F.R.; Hörnlein, C.; Setiawan, E.; Wörheide, G.; Erpenbeck, D.; Voogd, N.J. de.
The giant barrel sponge Xestospongia testudinaria is an ecologically important species that is widely distributed across the Indo-Pacific. Little is known, however, about the precise biogeographic distribution and the amount of morphological and genetic variation in this species. Here we provide the first detailed, fine-scaled (<200 km2) study of the morphological and genetic composition of X. testudinaria around Lembeh Island, Indonesia. Two mitochondrial (CO1 and ATP6 genes) and one nuclear (ATP synthase β intron) DNA markers were used to assess genetic variation. We identified four distinct morphotypes of X. testudinaria around Lembeh Island. These morphotypes were genetically differentiated with both mitochondrial and nuclear markers. Our results...

Mycale species (Porifera: Poecilosclerida) of Northwest Africa and the Macaronesian Islands Naturalis
Soest, R.W.M. van; Beglinger, E.J.; Voogd, N.J. de.
Based on collections assembled by Dutch expeditions to the Northwest African region, including the offshore islands in the neighbouring Atlantic, a taxonomic monograph of sponges of the genus Mycale is presented. Additional material from the region borrowed from the Zoologisk Museum of the University of Copenhagen and incidental samples made by individual collectors were also included. The combined collections contained sixteen species, nine of which are new to science: Mycale (Aegogropila) syringosimilis spec. nov., Mycale (Aegogropila) tenerifensis spec. nov., Mycale (Arenochalina) africamucosa spec. nov., Mycale (Carmia) atropha spec. nov., Mycale (Carmia) guineensis spec. nov., Mycale (Naviculina) cruzi spec. nov., Mycale (Paresperella) janvermeuleni...

Phylogeography of the Sponge Suberites diversicolor in Indonesia: insights into the evolution of marine lake populations Naturalis
Becking, L.E.; Erpenbeck, D.; Peijnenburg, K.T.C.A.; Voogd, N.J. de.
The existence of multiple independently derived populations in landlocked marine lakes provides an opportunity for fundamental research into the role of isolation in population divergence and speciation in marine taxa. Marine lakes are landlocked water bodies that maintain a marine character through narrow submarine connections to the sea and could be regarded as the marine equivalents of terrestrial islands. The sponge Suberites diversicolor (Porifera: Demospongiae: Suberitidae) is typical of marine lake habitats in the Indo-Australian Archipelago. Four molecular markers (two mitochondrial and two nuclear) were employed to study genetic structure of populations within and between marine lakes in Indonesia and three coastal locations in Indonesia,...

Skeletons in confusion: a review of astrophorid sponges with (dicho-)calthrops as structural megascleres (Porifera, Demospongiae, Astrophorida) Naturalis
Soest, R.W.M. van; Beglinger, E.J.; Voogd, N.J. de.
We present a review of astrophorid species possessing calthrops megascleres as structural megascleres (including species with dichotriaene modifi cations, but excluding mesotriaene and trichotriaene bearing species). Radiating oxeas characteristic of most astrophorids are lacking in such sponges, but auxiliary oxeas are apparently present in some species. Th ese sponges are currently assigned to two families, Pachastrellidae with four nominal genera Dercitus, Stoeba, Dercitancorina, Halinastra (the latter two generally considered junior synonyms of Stoeba), and Calthropellidae with nominal genera Calthropella, Corticellopsis (usually considered a junior synonym), Pachataxa and Pachastrissa. Our review of many original specimens and extensive new material...

Sponge beta diversity in the Spermonde Archipelago, SW Sulawesi, Indonesia Naturalis
Voogd, N.J. de; Cleary, D.F.R.; Hoeksema, B.W.; Noor, A.; Soest, R.W.M. van.
Sponge assemblages were investigated in the Spermonde Archipelago, southwestern Sulawesi, Indonesia. In this study spatial patterns of sponge similarity among sites were significantly related to remotely sensed environmental variables, the degree of human settlement and depth, but not to the distance between sites. Both oviparous and viviparous species groups responded to similar environmental constraints, and differences in similarity were unrelated to the distance between sites. The degree of human settlement, however, was significantly related to variation in the composition of viviparous, but not oviparous species. Our results demonstrate, most importantly, the utility of remotely sensed data in predicting the spatial turnover of diverse species...

Sponge interactions with spatial competitors in the Spermonde Archipelago Naturalis
Voogd, N.J. de; Becking, L.E.; Hoeksema, B.W.; Noor, A.; Soest, R.W.M. van.
This study describes the in situ effects of four bioactive sponges on their neighbours at three different locations and two depths in the Spermonde Archipelago, SW Sulawesi, Indonesia. The natural rates of interaction between the sponge species and eight possible competitive invertebrate groups were defined and quantified in circular subplots, this was repeated 25x for each of the four species and for each location and depth. Most interactions occurred with other sponges and with corals. Coral overgrowth by the four target species caused necrosis in more than 85 % of these interactions, whereas this was less than 25 % in sponge overgrowths. These results suggest that the toxins are used in spatial competition and that the concentrations of the bioactive...

Unforeseen importance of historical collections as baselines to determine biotic change of coral reefs: the Saba Bank case Naturalis
Hoeksema, B.W.; Land, J. van der; Meij, S.E.T. van der; Ofwegen, L.P. van; Reijnen, B.T.; Soest, R.W.M. van; Voogd, N.J. de.
Botanical and zoological collections may serve as archives for historical ecological research on the effects of global change and human impact on coral reef biota. Museum collections may harbour old specimens of reef-dwelling species that have become locally extinct. Such collections also help to determine whether early records of invasive species can be obtained from times when they were not yet recognized as such. A case study (2006) involving Saba Bank, Caribbean Netherlands (former Netherlands Antilles), suggests that the coral reef fauna here may have become impoverished when compared with data obtained during an earlier expedition in 1972. However, the 1972 sampling may have been incomplete, as it was performed by professional divers who were not...
