An ambitious, yet fundamental goal for comparative biology is to understand the evolutionary relationships for all of life. However, many important taxonomic groups have remained recalcitrant to inclusion into broader scale studies. Here, we focus on collection of 9 new 454 transcriptome data sets from Ostracoda, an ancient and diverse group with a dense fossil record, which is often undersampl...

In five groups of luminous animals it can be shown that luminescence is connected with the oxidation of a substance, luciferin, in aqueous solution, in presence of an enzyme, luciferase, and dissolved oxygen. In the mollusc, Pholas dactylus, Dubois (1) has been able to oxidize Pholas luciferin with luminescence by KMn04, HzO, BaOz, PbOa, and hypochlorites. I have been unable to oxidize with lum...

Ostracods form an important part of benthic biota. They form a feed to many fish, insects, insect larvae and even corals. In the vast aquatic biome both freshwater and sea they occupy an important place in the food chain. Experiments were conducted on a freshwater ostracod species, Chrissia halyi, culturing them in the laboratory along with chlodophora the feed. The feed was first exposed to le...
