Marine molluscs were surveyed at 42 stations: 41 by SCUBA and one intertidal beach survey. A total of 279 species of marine molluscs in three classes were recorded: 181 species of gastropods in 53 families, 97 species of bivalves in 26 families and a single species of cephalopod (Sepia pharaonis Ehrenberg, 1831). A mean of 21.8 species was recorded per site. The range was from 4 to 96 species. The highest diversity site was at Kyun Philar Island. The most widespread species were the pearl oyster Pinctada margaritifera (Linnaeus, 1758) (33 sites), muricid Chicoreus ramosus (Linnaeus, 1758) (21 stations), turbinid Astralium rhodostomum (Lamarck, 1822) (19 sites) and the wing shell Pteria penguin (Röding, 1798) (16 sites). Data from this study were compared with molluscan studies from the Gulf of Thailand, the Andaman Sea sites in Thailand and Singapore. Fifty-eight mollusc species in Myanmar were not found in the other areas. -
Recent Advances in Chiral Analysis of Proteins and Peptides
separations Review Recent Advances in Chiral Analysis of Proteins and Peptides Marine Morvan 1,2,* and Ivan Mikšík 1,2,* 1 Institute of Physiology of the Czech Academy of Sciences, Vídeˇnská 1083, 142 20 Prague, Czech Republic 2 Department of Analytical Chemistry, Faculty of Chemical Technology, University of Pardubice, Studentská 573, 532 10 Pardubice, Czech Republic * Correspondence: [email protected] (M.M.); [email protected] (I.M.) Abstract: Like many biological compounds, proteins are found primarily in their homochiral form. However, homochirality is not guaranteed throughout life. Determining their chiral proteinogenic sequence is a complex analytical challenge. This is because certain D-amino acids contained in proteins play a role in human health and disease. This is the case, for example, with D-Asp in elastin, b-amyloid and a-crystallin which, respectively, have an action on arteriosclerosis, Alzheimer’s disease and cataracts. Sequence-dependent and sequence-independent are the two strategies for detecting the presence and position of D-amino acids in proteins. These methods rely on enzymatic digestion by a site-specific enzyme and acid hydrolysis in a deuterium or tritium environment to limit the natural racemization of amino acids. In this review, chromatographic and electrophoretic techniques, such as LC, SFC, GC and CE, will be recently developed (2018–2020) for the enantioseparation of amino acids and peptides. For future work, the discovery and development of new chiral stationary phases and derivatization reagents could increase the resolution of chiral separations.

(UPD, Philippines) in September 2003 for the degree of Doctor of Philosophy in Marine Biology within the School of Marine Biology and Aquaculture James Cook University ABSTRACT The aim of this thesis is to describe the distribution of coral reef and shore gastropods in the Philippines, using the species rich taxa, Nerita, Clypeomorus, Muricidae, Littorinidae, Conus and Oliva. These taxa represent the major gastropod groups in the intertidal and shallow water ecosystems of the Philippines. This distribution is described with reference to the McManus (1985) basin isolation hypothesis of species diversity in Southeast Asia. I examine species-area relationships, range sizes and shapes, major ecological factors that may affect these relationships and ranges, and a phylogeny of one taxon. Range shape and orientation is largely determined by geography. Large ranges are typical of mid-intertidal herbivorous species. Triangualar shaped or narrow ranges are typical of carnivorous taxa. Narrow, overlapping distributions are more common in the central Philippines. The frequency of range sizesin the Philippines has the right skew typical of tropical high diversity systems. -
THE LISTING of PHILIPPINE MARINE MOLLUSKS Guido T
August 2017 Guido T. Poppe A LISTING OF PHILIPPINE MARINE MOLLUSKS - V1.00 THE LISTING OF PHILIPPINE MARINE MOLLUSKS Guido T. Poppe INTRODUCTION The publication of Philippine Marine Mollusks, Volumes 1 to 4 has been a revelation to the conchological community. Apart from being the delight of collectors, the PMM started a new way of layout and publishing - followed today by many authors. Internet technology has allowed more than 50 experts worldwide to work on the collection that forms the base of the 4 PMM books. This expertise, together with modern means of identification has allowed a quality in determinations which is unique in books covering a geographical area. Our Volume 1 was published only 9 years ago: in 2008. Since that time “a lot” has changed. Finally, after almost two decades, the digital world has been embraced by the scientific community, and a new generation of young scientists appeared, well acquainted with text processors, internet communication and digital photographic skills. Museums all over the planet start putting the holotypes online – a still ongoing process – which saves taxonomists from huge confusion and “guessing” about how animals look like. Initiatives as Biodiversity Heritage Library made accessible huge libraries to many thousands of biologists who, without that, were not able to publish properly. The process of all these technological revolutions is ongoing and improves taxonomy and nomenclature in a way which is unprecedented. All this caused an acceleration in the nomenclatural field: both in quantity and in quality of expertise and fieldwork. The above changes are not without huge problematics. Many studies are carried out on the wide diversity of these problems and even books are written on the subject. -

S. Krishnan): [email protected]. Abstract Radular morphologies of 22 species of the genus Conus from Indian coastal waters were analyzed by optical and scanning elec- tron microscopy. Although the majority of species in the present study are vermivorous, all three feeding modes known to occur in the genus are represented. Specific radular-tooth structures consistently define feeding modes. Species showing simi- lar feeding modes also show fine differences in radular structures. We propose that these structures will be of value in species identification in cases of ambiguity in other characteristics. Examination of eight discrete radular-tooth components has allowed us to classify the studied species of Conus into three groups. We see much greater inter-specific differences amongst vermivorous than amongst molluscivorous and piscivorous species. We have used these differences to provide a formula for species identification. The radular teeth of Conus araneosus, C. augur, C. bayani, C. biliosus, C. hyaena, C. lentiginosus, C. loroisii, and C. malacanus are illustrated for the first time. In a few cases our study has also enabled the correction of some erroneous descriptions in the literature. -

Thesis Committee: Names Signatures Jon-Paul Bingham (Chair) ___________________________ Harry Ako ___________________________ Cynthia Hunter ___________________________ ii Acknowledgements The author would like to take a moment to appreciate a notable few out of the army of supporters who came out during this arduously long scholastic process without whom this work would never have been. First and foremost, a “thank you” is owed to the USDA TSTAR program whose funds kept the snails alive and solvents flowing through the RP-HPLC. Likewise, the infrastructure, teachings and financial support from the University of Hawai‘i and more specifically the College of Tropical Agriculture and Human Resources provided a fertile environment conducive to cutting edge science. Through the 3 years over which this study took place, I found myself indebted to two distinct groups of students from Dr. Bingham’s lab. Those who worked primarily in the biochemical laboratory saved countless weekend RP-HPLC runs from disaster through due diligence while patiently schooling me on my deficiencies in biochemical processes and techniques. -
