Twelve deposit-feeding species of tropical holothuroid echinoderms (families Holothuriidae and Stichopodidae) were surveyed for the presence of UV-absorbing mycosporine-like amino acids (MAAs) during Austral summer at Hicks Reef, Great Barrier Reef (GBR). An additional species belonging to the Synaptidae was collected in Austral winter from Shrimp Reef, GBR. Tissues of all species contained MAA...

Figure 1. Crown-of-thorns starfish and their legacy. (A) A group of crown-of-thorns starfish converge on the remaining small piece of living coral tissue (lc) on the surface of a tabular coral (Acropora sp.) The other coral tissue has just been consumed by the starfish so that only the white skeleton remains (cs). (B) After crown-of-thorns starfish have removed the living coral tissue, the expo...

Astrosterioside A, a sulfated steroidal hexasaccharide isolated from starfish Astropecten monacanthus showing potent anti-inflammatory activity, was synthesized in a convergent linear sequence of 24 steps and in 6.8% overall yield from adrenosterone.

STARFISH is a parallel le system simulator we built for our research into the concept of disk directed I O In this report we detail steps taken to tune the le systems supported by STARFISH which include a traditional parallel le system with caching and a disk directed I O system In particular we now support two phase I O use smarter disk scheduling increased the maximumnumber of outstanding req...
