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.

    453 EVOLUTION OF CILIARY FEEDING IN THE PROSOBRANCHIA, WITH AN ACCOUNT OF FEEDING IN GAPULUS UNGAR/GUS By C. M. Yonge, D.Se. University of Bristol (Text-figs. 1-6) CONTENTS PAGE Introduction 453 Rejection Currents in the Mantle Cavity of the Prosobranchia 453 Evolution of Ciliary Feeding 455 Vermetus novae-hollandiae . 456 Crepidula fornicata and other Calyptraeidae 457 Capulus ungaricus 459 Modification of gill filaments 461 Discussion. 465 Summary 467 References. 468 INTRODUCTION Ciliary feeding, of such widespread occurrence in the Lamellibranchia, is confined in the Gastropoda to a few scattered groups. In freshwater Pul- monata, such as Limnaea, cilia on the foot assist in feeding when the animal is creeping suspended from the surface film (Brockmeier, 1898). Thecoso- matous Pteropoda feed exclusively by the aid of cilia on the unpaired middle lobe and the paired side lobes of the foot, and an evolutionary series- Cavolinia-Cymbulia-Gleba-can be traced in which there is a progressive elaboration in the perfection of this mechanism and an accompanying reduc- tion in the buccal mass and associated structures handed down from carni- vorous ancestors (Yonge, 1926). Only in the few prosobranchs which have acquired ciliary feeding mechanisms do these represent a modification of the ctenidia as in the Lamellibranchia. They also, as it is the aim of this paper to show, represent a modification of the rejection currents present in the mantle cavity of typical prosobranchs. REJECTION CURRENTS IN THE MANTLE CAVITY OF THE PROSOBRANCHIA In typical Prosobranchia a respiratory current, created by the beating of the lateral cilia on the gill filaments, is drawn into the mantle cavity by way of the inhalent opening (frequently prolonged into a siphon, e.g.

  • ABSTRACT Title of Dissertation: PATTERNS IN
    ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range.

  • Faunal Change and Bathymetric Diversity Gradient in Deep-Sea Prosobranchs from Northeastern Atlantic

Despite the plethora of studies, geographic patterns of diversity in deep sea remain subject of speculation. This study considers a large dataset to examine the faunal change and depth-diversity gradient of prosobranch molluscs in the Porcupine Seabight and adjacent Abyssal Plain (NE Atlantic). Rates of species succession (addition and loss) increased rapidly with increasing depth and indicated four possible areas of faunal turnover at about 700, 1600, 2800 and 4100 m. Depth was a significant predictor of diversity, explaining nearly a quarter the variance. There was a pattern of decreasing diversity downslope from 250 m to 1500–1600 m, followed by an increase to high values at about 4000 m and then again, a fall to 4915 m. Processes causing diversity patterns of prosobranchs in the Porcupine Seabight and adjacent Abyssal Plain are likely to differ in magnitude or type, from those operating in other Atlantic areas. Introduction An increasing focus for biodiversity research in the deep sea has been to test for the existence of large-scale gradients in the diversity of marine soft- sediment fauna in deep sea (e.g.

VERMEIJ A B The limpet form in gastropods: evolution, distribution, and implications for the comparative study of history GEERAT J. VERMEIJ* Department of Earth and Planetary Science, University of California, Davis, Davis, CA,USA C D Received 19 April 2015; revised 30 June 2016; accepted for publication 30 June 2016 The limpet form – a cap-shaped or slipper-shaped univalved shell – convergently evolved in many gastropod lineages, but questions remain about when, how often, and under which circumstances it originated. Except for some predation-resistant limpets in shallow-water marine environments, limpets are not well adapted to intense competition and predation, leading to the prediction that they originated in refugial habitats where exposure to predators and competitors is low. A survey of fossil and living limpets indicates that the limpet form evolved independently in at least 54 lineages, with particularly frequent origins in early-diverging gastropod clades, as well as in Neritimorpha and Heterobranchia. There are at least 14 origins in freshwater and 10 in the deep sea, E F with known times ranging from the Cambrian to the Neogene.
