A hitherto unnoticed adaptive radiation: epitoniid species (Gastropoda: Epitoniidae) associated with corals (Scleractinia) Naturalis
Gittenberger, A.; Gittenberger, E..
Twenty-two epitoniid species that live associated with various hard coral species are described. Three genera, viz. Epidendrium gen. nov., Epifungium gen. nov., and Surrepifungium gen. nov., and ten species are introduced as new to science, viz. Epidendrium aureum spec. nov., E. sordidum spec. nov., Epifungium adgranulosa spec. nov., E. adgravis spec. nov., E. adscabra spec. nov., E. marki spec. nov., E. nielsi spec. nov., E. pseudolochi spec. nov., E. pseudotwilae spec. nov., Surrepifungium patamakanthini spec. nov., and ‘Epitonium’ crassicostatum spec. nov. and ‘E.’ graviarmatum spec. nov. Although their identities as separate gene pools are convincingly demonstrated by molecular data, some of these species cannot be identified unequivocally on the basis...

A molecularly based phylogeny reconstruction of mushroom corals (Scleractinia: Fungiidae) with taxonomic consequences and evolutionary implications for life history traits Naturalis
Gittenberger, A.; Reijnen, B.T.; Hoeksema, B.W..
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...

Ecological relevance of shipwrecks in the North Sea Naturalis
Lengkeek, W.; Coolen, J.W.P.; Gittenberger, A.; Schrieken, N..
This paper reports on observations made during wreck dive expeditions in 2010-2012, in order to investigate the ecological relevance of shipwrecks on the Dutch Continental Shelf (dcs). Shipwrecks are biodiversity hotspots. The number of species recorded on shipwrecks is similar to the number of species found in soft bottoms of the entire dcs. The soft substrates, however, represent a vastly larger habitat on the dcs than the shipwrecks. Amongst many other taxa, juvenile and large Atlantic cod, linear skeleton shrimp, goldsinny wrasses and leopard spotted gobies were found in the shipwreck habitats. The presence of these important species and their absence from many other habitats, illustrate that shipwrecks function as key habitats, nurseries, and refugia...

First record of a settled stomatopod Platysquilla eusebia in the North Sea (Malacostraca: Stomatopoda) Naturalis
Lewis, W.; Gittenberger, A..
This paper describes the discovery of a settled juvenile specimen of the stomatopod Platysquilla eusebia on the Dutch part of the Dogger Bank in the central North Sea. This is the northernmost record in Europe. The species is native to the Mediterranean and to the Atlantic coast from Portugal up to France. Further investigations have to show if the species already forms populations this far north. As the planktonic stages of P. eusebia have already been recorded in prior years, the establishment of the species should not be a problem, providing the circumstances are favourable.

Habitat preferences of coral-associated wentletrap snails (Gastropoda: Epitoniidae) Naturalis
Gittenberger, A.; Hoeksema, B.W..
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...

Attention is called for Lineus longissimus, the longest animal in the world, and especially for its occurrence in The Netherlands. A ribbon worm species new for the Dutch fauna is recorded: Emplectonema cf. echinoderma (Marion, 1873).

Mariene flora en fauna te boek Naturalis
Hoeksema, B.W.; Gittenberger, A..
Het aantal boeken over de Nederlandse flora en fauna neemt gestaag toe. En ook de afgelopen jaren zijn er weer aardig wat nieuwe titels uitgekomen over het Nederlandse zeeleven. Op deze pagina's vier van die boeken. Eerder, in de Onderwatersport van april 2005, is ook al een aantal titels gepresenteerd van publicaties die mogelijk de moeite waard zijn om kennis te vergaren over de planten en dieren die tijdens het duiken in Nederland de revue passeren.

Marine fauna of hard substrata of the Cleaver bank and Dogger bank Naturalis
Schrieken, N.; Gittenberger, A.; Coolen, J.W.P.; Lengkeek, W..
As most of the sea bottom in the Dutch part of the North Sea consists of sand, marine fauna that live in association with hard substrates are rarely monitored. We report here on the results of a species inventory in June 2011 done by scuba-diving while focusing on a wreck on the Dogger Bank and on rocky bottoms on the Cleaver Bank. This resulted in various new records of species for the Dutch part of the North Sea. This result appeared for a large part linked to the added value of monitoring with scuba-divers. It is therefore concluded that scuba-divers should be used in addition to the more traditional monitoring methods in which dredges and grabs are used, if one aims at getting an accurate view of the biodiversity present in marine regions like the...

Native and non-native species of hard substrata in the Dutch Wadden Sea Naturalis
Gittenberger, A.; Rensing, M.; Stegenga, H.; Hoeksema, B.W..
Bij een inventarisatie van hard substraat in 83 locaties in de Nederlandse Waddenzee, in zoutgehaltes van 10-32 ppt, werden in juli/augustus 2009 in totaal 129 soorten planten en dieren waargenomen. Van deze soorten hadden er 29 een uitheemse of onbekende oorsprong. In aanvulling hierop werd een inventarisatie gemaakt van nog ongepubliceerde waarnemingen in de Waddenzee. Elf soorten en één ondersoort waren nog niet eerder geregistreerd in de Nederlandse Waddenzee. Eén alg, Ceramiaceae sp., met onbekende oorsprong, is vermoedelijk een nieuwe soort voor Europa. Eén zakpijpsoort, Molgula socialis, is nieuw voor Nederland. Deze soort is waarschijnlijk algemeen verspreid in Nederland en is mogelijk zelf inheems. In het verleden was hij vermoedelijk vaak...

Nieuwe mosdiertjes van Noordzeewrakken (Bryozoa) Naturalis
Faasse, M.A.; Coolen, J.W.P.; Gittenberger, A.; Schrieken, N..
In het kader van het project ‘Duik de Noordzee Schoon’ worden scheepswrakken onderzocht, beschreven en van afval ontdaan. Scheepswrakken vormen een bijzonder leefgebied in het mariene milieu, met een hoge biodiversiteit. Dit bleek weer tijdens onderzoek van visnetten die van ver weg gelegen wrakken waren verwijderd. Hierbij werden maar liefst vier nieuwe mosdiertjes voor de Nederlandse fauna aangetroffen.

Phenotypic plasticity revealed by molecular studies on reef corals of Fungia (Cycloseris) spp. (Scleractinia: Fungiidae) near river outlets Naturalis
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....
