A New Species of Pla Tidia (brachiopoda) from the La Chapelle Bank Region
A new species of Platidia (Brachiopoda, Platidiidae) was dredged by R.V. 'Sarsia' in November 1956 in the La Chapelle Bank region, attached to the dead part of the coral Anisopsammia rostrata (Pourta1es).1 Eight entire specimens and two smashed were dredged at position 47° 30' N., 7° 20' W. at a depth of 870 to 970 fathoms, and one at position 47° 38' N., 7° 28' W. at 710 to 750 fathoms. All, e...
متن کاملIdentification of some secondary metabolites produced by four Penicillium species
Fungi produce a wide range of secondary metabolites such as antibiotics, toxins, alkaloids, fatty acids, ketones and alcohols during active cell growth. The present study was aimed to identify secondary metabolites from some Penicillium species, using GC-MS. Many important compounds such as 3-oxoquinuclidine in Penicillium jenseii, formamidine in Penicillium pusillum, orcinol and 1,3,8-p-mentha...
متن کاملMolecular paleobiological insights into the origin of the Brachiopoda.
Most studies of brachiopod evolution have been based on their extensive fossil record, but molecular techniques, due to their independence from the rock record, can offer new insights into the evolution of a clade. Previous molecular phylogenetic hypotheses of brachiopod interrelationships place phoronids within the brachiopods as the sister group to the inarticulates, whereas morphological con...
متن کاملBrachiopoda of Greece: an annotated checklist
BACKGROUND Until today, only scattered species records of Brachiopoda from Greece have been included in publications on the Mediterranean brachiopod fauna. These records were mostly based on material collected during marine expeditions in the eastern Mediterranean decades ago, while few recent additional records appear in ecological studies. The aim of this paper was to give the first checklist...
متن کاملLaminar shell structure of Antigonambonites planus (Pander, 1830) (Brachiopoda, Billingsellida)
The order Billingsellida comprises brachiopods with laminar and fibrous shells, however, the data on their microstructure are scanty and the taxonomic value of differences in their shell structure is uncertain. The shell structure of clitambonitidine Antigonambonites planus was found to be laminar, not fibrous as previously considered; possibly this shows that it belongs to the suborder Billing...
