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. -

Stuttgart, Baden-Württemberg, Germany 3Eberhard Karls Universität Tübingen. Tübingen, Baden-Württemberg, Germany 4Corresponding author: E-mail: [email protected] Architectonicidae is a diverse family of heterobranch sea snails comprising over 11 genera and 140 extant species distributed worldwide (Bieler & Petit, 2005). They live in shallow to deep water, and have turbinate to discoidal shells, with a typically wide umbilicus and a downward-pointing (heterostrophic) protoconch (Healy, 1998). Pseudotorinia phorcysi Cavallari, Salvador & Simone, 2013 is a deep-water species known only from its type locality in the SW Atlantic, off Cabo Frio, Rio de Janeiro state, Brazil (23°41'S 42°06'W, 430–450 m depth). Its original description was based on a single eroded juvenile specimen collected by the French-Brazilian expedition “Marion Dufresne” MD55 in the late 1980s (Cavallari et al., 2014). A recent review of the malacological collection of the Museu de Zoologia da Universidade de São Paulo (MZSP; São Paulo, Brazil) revealed a reasonably well-preserved adult specimen of P. phorcysi, collected in southern Brazilian waters. This effectively expands the species’ geographic and bathymetric ranges. -
The Diapsid Origin of Turtles
THE DIAPSID ORIGIN OF TURTLES Mrs. Basawarajeshwari Indur Dept of Zoology, Sharnbasva University, Kalaburagi. A B S T R A C T The origin of turtles has been a persistent unresolved problem involving unsettled questions in embryology, morphology, and paleontology. New fossil taxa from the early Late Triassic of China (Odontochelys) and the Late Middle Triassic of Germany (Pappochelys) now add to the understanding of (i) the evolutionary origin of the turtle shell, (ii) the ancestral structural pattern of the turtle skull, and (iii) the phylogenetic position of Testudines. As has long been postulated on the basis of molecular data, turtles evolved from diapsid reptiles and are more closely related to extant diapsids than to parareptiles, which had been suggested as stem group by some paleontologists. The turtle cranium with its secondarily closed temporal region represents a derived rather than a primitive condition and the plastron partially evolved through the fusion of gastralia Key word –Carapace, Plastron, Reptiles, Turtle origins I.INTRODUCTION The origin and early evolution of turtles has been a longstanding problem in vertebrate morphology and phylogeny (Rieppel and Reisz, 1999). The unique composition of the turtle shell as well as the closed (anapsid) architecture of the skull had been controversially debated issues for more than a century. The lack of fossils documenting plausible stem taxa predating the Late Triassic had long formed a major obstacle in this context. Until recently, the geologically oldest and most primitive stem turtles reached back only to the later part of the Late Triassic, whereas it was long thought that the turtle clade likely diverged from other reptiles already during the Permian. -

Paolo Giulio Albano Coordinatore Dottorato Relatore Prof.ssa Barbara Mantovani Prof. Francesco Zaccanti Co-relatore Prof. Bruno Sabelli Esame finale anno 2011 to Ilaria and Chiara, my daughters This PhD thesis is the completion of a long path from childhood amateur conchology to scientific research. Many people were involved in this journey, but key characters are three. Luca Marini, director of “Secche di Tor Paterno” Marine Protected Area, shared the project idea of field research on molluscs and trusted me in accomplishing the task. Without his active support in finding funds for the field activities this project would have not started. It is no exaggeration saying I would not have even thought of entering the PhD without him. Bruno Sabelli, my PhD advisor, is another person who trusted me above reasonable expectations. Witness of my childhood love for shells, he has become witness of my metamorphosis to a researcher. Last, but not least, Manuela, my wife, shared my objectives and supported me every single day despite the family challenges we had to face. Many more people helped profusely. I sincerely hope not to forget anyone. Marco Oliverio, Sabrina Macchioni, Letizia Argenti and Roberto Maltini were great SCUBA diving buddies during field activities. Betulla Morello, former researcher at ISMAR-CNR in Ancona, was my guide through the previously unexplored land of non-parametric multivariate statistics. -
A Reassessment of the Taxonomic Position of Mesosaurs, and a Surprising Phylogeny of Early Amniotes
ORIGINAL RESEARCH published: 02 November 2017 doi: 10.3389/feart.2017.00088 A Reassessment of the Taxonomic Position of Mesosaurs, and a Surprising Phylogeny of Early Amniotes Michel Laurin 1* and Graciela H. Piñeiro 2 1 CR2P (UMR 7207) Centre de Recherche sur la Paléobiodiversité et les Paléoenvironnements (Centre National de la Recherche Scientifique/MNHN/UPMC, Sorbonne Universités), Paris, France, 2 Departamento de Paleontología, Facultad de Ciencias, University of the Republic, Montevideo, Uruguay We reassess the phylogenetic position of mesosaurs by using a data matrix that is updated and slightly expanded from a matrix that the first author published in 1995 with his former thesis advisor. The revised matrix, which incorporates anatomical information published in the last 20 years and observations on several mesosaur specimens (mostly from Uruguay) includes 17 terminal taxa and 129 characters (four more taxa and five more characters than the original matrix from 1995). The new matrix also differs by incorporating more ordered characters (all morphoclines were ordered). Parsimony Edited by: analyses in PAUP 4 using the branch and bound algorithm show that the new matrix Holly Woodward, Oklahoma State University, supports a position of mesosaurs at the very base of Sauropsida, as suggested by the United States first author in 1995. The exclusion of mesosaurs from a less inclusive clade of sauropsids Reviewed by: is supported by a Bremer (Decay) index of 4 and a bootstrap frequency of 66%, both of Michael S. Lee, which suggest that this result is moderately robust. The most parsimonious trees include South Australian Museum, Australia Juliana Sterli, some unexpected results, such as placing the anapsid reptile Paleothyris near the base of Consejo Nacional de Investigaciones diapsids, and all of parareptiles as the sister-group of younginiforms (the most crownward Científicas y Técnicas (CONICET), Argentina diapsids included in the analyses). -
