We present the results of the first ever research on biodiversity and biogeography of marine benthic diatoms from coral reefs of the tropical islands of Indonesia, including West Borneo, East Java, South Celebes, Komodo, Rinca and Flores. The sampled islands offer a broad range of coral reef microhabitats and host diatom assemblages from seaweeds,...

Intricate mesoporous biosilica has many biomedical applications as a nanocarrier. However, its potential use in photodynamic therapy (PDT) has received little attention. This work reports the first fabrication of bio-engineered materials by covalently conjugating C-phycocyanin (C-PC), a natural photosensitizer, to biosilica for the PDT of tumor-ass...

Background The Aegean Sea coast of Turkey hosts one of the most important nesting grounds for loggerhead sea turtles ( Caretta caretta ) in the Mediterranean Sea. Previous studies have revealed that the sea turtle carapace provides favourable conditions for various epibiontic organisms. Epibionts occurring on the carapace have been examined from di...

Although previous phylogenetic analyses suggested that the araphid diatom family Plagiogrammaceae is monophyletic, there is still not a clear understanding of relationships among the genera, and the taxonomy of several genera --Dimeregramma and Plagiogramma--remains questionable in light of paraphyly for both genera using molecular and morphologica...

We describe the new species Gomphonemopsis sieminskae from brackish waters of the East China Sea littoral near Ningbo, China. Two diatom strains isolated from Ulva sp. were successfully grown, then analyzed by light (LM) and scanning electron (SEM) microscopy. The new species is compared to known Gomphonemopsis species, and similarities to G . pseu...

New molecular and morphological insights are presented on Campylosira africana and two new species, Extubocellulus cupola sp. nov. and Plagiogrammopsis castigatus sp. nov. Species descriptions were based on LM/SEM micrographs and a dataset with concatenated sequences of SSU, rbcL and psbC loci constructed from 56 cymatosiroid strains isolated from...

The marine diatom Olifantiella Riaux–Gobin et Compère predominantly occurs in tropical Indo– Pacific coral reef environments. The genus has about a dozen validly published taxa and is characterized by transapically elongate striae composed of a macroareola, broad perforated girdle, and tubular buciniportula process of trumpet–shape. The valve mantl...

The focus of this paper is the sexual reproduction and phylogeny of Schizostauron Grunow, which were studied using clonal cultures isolated from the Indian Ocean coast of Mozambique near Tofo and Bazaruto. Taxa of Schizostauron were characterized by light and electron microscopy and a phylogeny derived from three genes (rbcL, psbC and short subunit...

Diatoms are important contributors to the benthic microeukaryote flora. This manuscript lays the foundation for future metagenomic and environmental sequencing projects off coastal China by curating diatom DNA sequences from the Yantai region of the Bohai and Yellow Seas (Northeast China). These studies are based on cultures established from sample...

Species belonging in the genus Simonsenia, including S. delognei, have been studied by means of light and electron microscopy. One of them, from estuarine environments in the Guadiana River (Atlanticcoast, close to the border of southern Portugal) has also been maintained in culture, making it possible to use molecular (rbcL gene) data to study its...
