One important foundation for the conservation of biodiversity on islands is an inventory of endemic species. In the absence of a comprehensive inventory, conservation effort often defaults to a focus on the better-known and more conspicuous species (typically mammals and birds). Although this component of island biota often needs such conservation attention, such focus may mean that less conspicuous endemic species (especially invertebrates) are neglected and suffer high rates of loss. In this paper, we review the available literature and online resources to compile a list of endemic species that is as comprehensive as possible for the 137 km2 oceanic Christmas Island, an Australian territory in the north-eastern Indian Ocean.

  • Echinodermata Associated with Coral Reefs of Andaman and Nicobar Islands
    Rec. zoo!. Surv. India: 100 (Part 3-4) : 21-60, 2002 ECHINODERMATA ASSOCIATED WITH CORAL REEFS OF ANDAMAN AND NICOBAR ISLANDS D. R. K. SASTRY Zoological Survey of India, A & N Regional Station, Port Blair - 744 102 INTRODUCTION Coral reefs are an important ecosystem of the coastal environment. The reef ecosystem IS highly productive and provides substratum, shelter, food etc. to a variety of biota. Consequently a number of faunal and floral elements are attracted towards the reef ecosystem and are closely associated with each other to form a community. Thus the reefs are also rich in biodiversity. Among the coral reef associates echinoderms are a conspicuous element on account of their size, abundance and effect on the reef ecosystem including the corals. In spite of their importance in the coral reef ecosystem and its conservation, very few studies were made on the echinoderm associates of the coral reefs. Though there were some studies elsewhere, the information on reef­ associated echinoderms of Indian coast is meager and scattered (see Anon, 1995). Hence an attempt is made here to collate the scattered accounts and unpublished information available with Zoological Survey of India. Since the information is from several originals and quoted references and many are to be cited often, these are avoided in the text and a comprehensive bibliography is appended which served as source material and also provides additional references of details and further information. ECHINODERMS OF CORAL REEFS More than 200 species of echinoderms occur in the reef ecosystem of Andaman and Nicobar Islands. These belong to five extant classes with 30 to 60 species of each class.

Patterns of geographic variability, particularly with respect to color phenotypes, are evident in many organisms and may provide visual evidence of natural selection. This dissertation examined the geographic and genetic variability of color patterns and morphology of the sea urchin Lytechinus variegatus. This study had 3 objectives: 1) to describe and quantify phenotypic diversity—color and morphology— throughout the geographic range; 2) to determine the heritability of color in genetic crosses between individuals with similar and differing phenotype; 3) to assess the degree of genetic divergence between and within the regions and congruence between the phylogenetic mitochondrial COI data and color phenotypes seen in the field.

  • 263 Physical Properties of Gametes in Three Sea Urchin
    J. exp. Biol. 194, 263–284 (1994) 263 Printed in Great Britain © The Company of Biologists Limited 1994 PHYSICAL PROPERTIES OF GAMETES IN THREE SEA URCHIN SPECIES FLORENCE I. M. THOMAS* University of California at Berkeley, Berkeley, CA 94720, USA Accepted 1 June 1994 Summary Physical properties (density in kg m23, viscosity, sinking rates and dispersion rate) of the gametes and associated spawned materials were measured for three species of sea urchin, Tripneustes gratilla, Echinometra mathaei and Colobocentrotus atratus, from habitats that differ in wave exposure. The gametes of all three species are negatively buoyant, highly viscous and exhibit shear-thinning (a decrease in viscosity with increasing shear rate). Female gametes are more viscous than male gametes, and the viscosity of female gametes differs among the three species. The viscosity of female gametes is highest for C. atratus, the species from habitats most exposed to wave action. Within the species T. gratilla, viscosity of female gametes is higher in habitats exposed to wave action than in more protected habitats. Evidence reported in this paper suggests that the shear-thinning of gametes may provide a performance advantage for these sea urchins. High viscosity of gametes at low shear rates may decrease gamete dispersal upon release and, under certain flow conditions, allow gametes to form strings and clumps on the surface of the urchin. Depending upon the morphology of the surface, these clumps or strings may be retained and fertilization may occur within these clumps or strings. Conversely, low viscosity of gametes at high shear rates decreases the power required to extrude gametes through the gonoduct during spawning.
