Palytoxin (PTX) is a potent marine toxin that was originally found in soft corals from tropical areas of the Pacific Ocean. Soon after, its occurrence was observed in numerous other marine organisms from the same ecological region. More recently, several analogs of PTX were discovered, remarkably all from species of the dinoflagellate genus Ostreopsis. Since these dinoflagellates are also found...

The role of the audiologist in aural rehabilitation services on behalf of older adults with hearing impairment is expanding, just as our knowledge of hearing in aging likewise expands [1]. In the pa st, audiologists generally found that they could not do as much as they desired to assist their older patients in acoustic design modifications to alleviate or prevent environmental interference in ...

Modern techniques for sensor array signal processing are hampered by the often un realistic and overly simplistic assumptions used in their development Foremost among these assumptions are those relating to the array geometry or response including for example known sensor positions availability of complete gain phase mutual coupling calibration data uniform linear arrays etc Of course with real...

the present study reports the changes in the phytoplankton community structure in taklong island national marine reserve (tinmar), guimaras island, philippines. quantification of pah yielded undetectable results, whereas, primary productivity, phytoplankton density, and diversity values were higher as compared to samples before the oil spill and samples from the reference site. sixty-nine gener...

background and objectives: in marine actinomycetes, carotenoid production occurs in constitutive, light-dependent or cryptic manner. the present work deals with the fermentative production of carotenoids from marine actinomycetes. materials and methods: marine actinomycetes namely streptomyces strain aqbmm35 was isolated from the marine sponge mycale mytilorum collected from south west coast of...

Ocean, which covers approximately 71% of the earth’s surface, is an ancient and mysterious habitat with diversiform marine ecosystem. Millions of unique marine organisms survive in this high-salt, hypertonic, tenebrous, and microthermal liquid environment [1,2] and these extreme living environments endowed them the special capacity for producing structurally and biofunctionally unique metabolit...

The ecosystem-based approach (EA) to the management of marine resources has been the focus of several recent publications (e.g. Browman & Stergiou 2004, Pikitch et al. 2004, Beddington & Kirkwood 2005, Daan et al. 2005). Despite this flurry of articles, the often over-riding importance of political and socio-economic forces in establishing and implementing the EA have not been adequately addres...
