The present study focuses on the biochemical aspects of six islands belonging to Lakshadweep Archipelago – namely Kavaratti, Kadamath, Kiltan, Androth, Agathy and Minicoy. Lakshadweep, which is an area biologically significant due to isolation from the major coastline, remains as one of the least studied areas in Indian Ocean. The work, processed out the distributional pattern of trace metals among the biotic (corols, sea weeds and sea grass) and abiotic component (sediments) of ecosystem. An effort is made to picturise the spatial distribution pattern of different forms of nitrogen and phosphorus in the various sedimentary environments of the study area. Studies on the biogeochemical and nutrient aspects of the concerned study area scanty. In Lakshadweep, the local life is very dependent on reefs and its resources. The important stress which produce a threatening effort on the existence for coral reefs are anthropogenic-namely-organic and inorganic pollution from sewage, agricultural and industrial waters, sediment damage from excessive land cleaning, and over exploitation particularly through destructive fishing methods. In addition these one other more localized or less service anthropogenic stress: pollution by oil and other hydrocarbons, complex organic molecular and heavy metal pollution, and destructive engineering practices.

In the present thesis the petrographic, geochemical and digenetic variability of the sediments in the islands of Kavaratti and Minicoy has been investigated .The beach profile studies show that in the Kavaratti lagoon beach, the slope is steeper in the southern and south central part than in the northern end’s marginal deposition is taking place in the northern end of the Kavaratti island, whereas a marginal erosion is observed at the southern end. In Minicoy the slope of the lagoon beach is gentle in the south and is slightly steeper at the northern part of the beach. The southern and northern beach sections show a marginal deposition. Based on the mineralogical and geochemical studies it is concluded that the main digenetic changes observed is the transformation of aragonite to LMC.The transformation takes place mainly in the vadose zone and is caused by the abundance of fresh water infiltration.

The present study aims at surveying the coral lagoons of four islands viz. Kavarathi, Kalpeni, Kadmat and Agathi, which include quantitative survey of the major benthic forms using Line Intercept Transect (LIT) technique and hydrographical study of these lagoon waters The distribution of PHC in the lagoons has also been followed to understand, the effects of introduction of flat bottomed ferry boats to the islands.From a biological monitoring stand point for the assessment of manmade disturbance of the coral reefs, it IS highly essential to identify faunal assemblages which will contain 'flag-stones' specIes as indicators of such disturbances. Among the known faunal assemblages In coral reefs the most diverse groups of sensitive species belongs to bryozoan assemblage. Therefore, the most common species of bryozoans distributed along the atolls and reef flats were collected and described in this work Along with this, bryozoans associated with coral from other parts of Indian ocean have also been added so as to provide a comprehensive picture of the distribution of bryozoans in the coral reefs.

Coral Reefs are marine, biogenic, wave resistant carbonate structures, formed of the skeletal remains of hermatypic, or reef building organisms. The main reef builders are calcifying Rhodophytes, molluscs, sponges, polychaetes and Cnidarians. Among them, scleractinian corals and hydrocorallians are by far the most important contributors to the formation of reefs. Coral reefs cover approximately 600 thousand square kilometers of the earth's surface (Crossland fl a_1., 1991) which is about 2x106 square kilometres of tropical oceans.

Hepcidin is a family of short cysteine-rich antimicrobial peptides (AMPs) participating in various physiological functions with inevitable role in host immune responses. Present study deals with identification and characterisation of a novel hepcidin isoform from coral fish Zanclus cornutus. The 81 amino acid (aa) preprohepcidin obtained from Z. cornutus consists of a hydrophobic aa rich 22 mer signal peptide, a highly variable proregion of 35 aa and a bioactive mature peptide with 8 conserved cysteine residues which contribute to the disulphide back bone. The mature hepcidin, Zc-hepc1 has a theoretical isoelectric point of 7.46, a predicted molecular weight of 2.43 kDa and a net positive charge of ?1. Phylogenetic analysis grouped Z. cornutus hepcidin with HAMP2 group hepcidins confirming the divergent evolution of hepcidin-like peptide in fishes. Zc-hepc1 can attain a b-hairpin-like structure with two antiparallel b-sheets. This is the first report of an AMP from the coral fish Z. cornutus.

Esta breve publicaci??n tiene por objeto contribuir al conocimiento del proceso de construcci??n de una aldea de morfolog??a alveolar, tan caracter??stica en el ??mbito de Cantabria. A trav??s del estudio se pretenden formular hip??tesis sobre sus transformaciones hist??ricas, mostrar los tipos de casas que componen su entramado urbano y definir criterios que permitan avanzar en la investigaci??n de este tema. Este documento es el resultado de la labor pr??ctica de un grupo de licenciados durante el curso de doctorado del Departamento de Geograf??a, Urbanismo y Ordenaci??n del Territorio impartido en 1992-93. Los dibujos de los tipos arquitect??nicos, constituyen un documento de gran calidad, y puede servir como gu??a para cualquier persona que desee visitar la ladea de Cos y para que comprenda la variedad y riqueza de su patrimonio arquitect??nico.

Defiende la idea de que el taller de canto coral, que potencia la actividad artística y emocional, puede servir de tratamiento para personas con problemas de autoestima, autocontrol y bajo dominio de las habilidades sociales. Como apoyo a esta teoría, hace un recorrido por la historia de la filosofía destacando los autores que defienden la educación de los sentidos como objetivo del aprendizaje. Finaliza con una descripción de las facetas que el adulto puede desarrollar a través de la actividad coral.
