Anemone¢shes (genera: Amphiprion and Premnas; family Pomacentridae) are a group of 28 species of coral reef ¢shes that are found in obligate symbiosis with large tropical sea anemones. A phylogenetic hypothesis based on morphological analyses of this group suggests that the ancestral anemone¢sh was a generalist with similar morphology to other pomacentrids, and that it gave rise to other anemon...

Marine environment is the main source of natural bioactive products whose chemical-structural properties are not similar with other natural products of plants and other inland organisms. The present study was carried out to evaluate antibiotic properties of diethyl ether and methanol extracts of two marine species including starfish and carpet anemone. The samples of starfish and carpet anemone...

Crabs of the genus Lybia have the remarkable habit of holding a sea anemone in each of their claws. This partnership appears to be obligate, at least on the part of the crab. The present study focuses on Lybia leptochelis from the Red Sea holding anemones of the genus Alicia (family Aliciidae). These anemones have not been found free living, only in association with L. leptochelis. In an attemp...

Toxin II isolated from the sea anemone Anemonia sulcata enhances activation of the action potential sodium ionophore of electrically excitable neuroblastoma cells by veratridine and batrachotoxin. This heterotropic cooperative effect is identical to that observed previously with scorpion toxin but occurs at a 110-fold higher concentration. Depolarization of the neuroblastoma cells inhibits the ...

Twenty-six species of anemonefish of the genera Amphiprion and monospecific Premnas, use only 10 species of anemones as hosts in the wild (Families: Actiniidae, Stichodactylidae and Thalassianthidae). Of these 10 anemone species some are used by multiple species of anemonefish while others have only a single anemonefish symbiont. Past studies have explored the different patterns of usage betwee...

The Ranunculaceae genus Anemone (order Ranunculales), comprising more than 150 species, mostly herbs, has long been used in folk medicine and worldwide ethnomedicine. Various medicinal compounds have been found in Anemone plants, especially triterpenoid saponins, some of which have shown anti-cancer activities. Some Anemone compounds and extracts display immunomodulatory, anti-inflammatory, ant...

Acontia, located in the gastrovascular cavity of anemone, are thread-like tissue containing numerous stinging cells which serve as a unique defense tissue against predators of the immobile acontiarian sea anemone. Although its morphology and biological functions, such as defense and digestion, have been studied, the defense behavior and the specific events of acontia ejection and retraction are...

There is a constant battle to break even between continuing improvements in DRAM capacities and the growing memory demands of large-memory high-performance applications. Performance of such applications degrades quickly once the system hits the physical memory limit and starts swapping to the local disk. In this paper, we investigate the benefits and tradeoffs in pooling together the collective...

There is a constant battle to break even between continuing improvements in DRAM capacities and the growing memory demands of large-memory high-performance applications. Performance of such applications degrades quickly once the system hits the physical memory limit and starts swapping to the local disk. We present the design, implementation and evaluation of Anemone – an Adaptive Network Memor...

Morphological and molecular evidence strongly supported the monophyly of tribe Anemoneae DC.; however, phylogenetic relationships among genera of this tribe have still not been fully resolved. In this study, we sampled 120 specimens representing 82 taxa of tribe Anemoneae. One nuclear ribosomal internal transcribed spacer (nrITS) and six plastid markers (atpB-rbcL, matK, psbA-trnQ, rpoB-trnC, r...
