A general study with the objective to classify ecotoxicity status of macrobenthose associated with dominant toxic zoanthids in Hormuz Island is presented. Hence, a novel model based on hard bottom macrobenthos and the related substrate composition was suggested to be used for testing the accumulated palytoxin (PTX) in macrobenthose exposed to Zoanthus sansibaricus. Direct and rapid assessment i...

Three new norzoanthamine-type alkaloids, named 2-hydroxy-11-ketonorzoan thamide B (1), norzoanthamide B (2) and 15-hydroxynorzoanthamine (3), were isolated from Zoanthus sp. specimens collected at the Canary Islands. Their structures were determined by interpretation of NMR and HR-ESIMS data. Relative configurations of their chiral centers were proposed on the basis of ROESY spectra and by comp...

10 Observational analyses reveal that variations in sea surface temperatures (SST) in the 11 Kuroshio-Oyashio extension (KOE) region of the North Pacific are associated with two dis12 tinct and robust patterns of atmospheric variability: 1) a pattern that peaks in amplitude 13 approximately 2 3 weeks prior to large KOE SST anomalies, and is consistent with atmo14 spheric forcing of the SST fiel...

Despite great advances in practical applications of fluorescent proteins (FPs), their natural function is poorly understood. FPs display complex spatio-temporal expression patterns in living Anthozoa coral polyps. Here we applied confocal microscopy, specifically, the fluorescence recovery after photobleaching (FRAP) technique to analyze intracellular localization and mobility of endogenous FPs...

Background: Sponges and sea anemones do not have specialized defense organs. Instead, they rival harmful microorganisms by producing certain compounds. These compounds can also be useful against some human pathogens. This study aimed to investigate the antimicrobial effects of bioactive products from these marine animals. Methods: Two species of sea anemone <e...

Long term fluctuations in the abundance of common squid, Todarodes pacificus are taken in the waters around Korea and Japan from 1952 to 2003. The year-to-year fluctuations in the abundance in the Tsushima Warm current (TWC) region (Yellow sea- east China sea-east/Japan sea) revealed the same pattern with that in the Kuroshio-Oyashio Current (KOC) region (Northern Pacific) except for the period...
