This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an estimated 8,000-20,000 species, bivalves represent the second largest living class of molluscs (Bieler et al. 2013). Revived interest in molluscan phylogeny has resulted in a torrent of molecular sequence data from phylogenetic, mitogenomic, and phylogenomic studies. Despite recent progress, basal relationships of the class Bivalvia remain contentious, owing to conflicting hypotheses often between morphology and molecules.

Available in PDF, EPUB and Kindle. Book excerpt: Bivalves are key components of recent marine and freshwater ecosystems and have been so for most of the Phanerozoic. Their rich and long fossil record, combined with their abundance and diversity in modern seas, has made bivalves the ideal subject of palaeobiological and evolutionary studies. Despite this, however, topics such as the early evolution of the class, relationships between various taxa and the life habits of some key extinct forms have remained remarkably unclear. This volume integrates palaeontological and zoological approaches and sheds new light on the course of bivalve evolution.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lucinidae are the most specious family of chemosymbiotic bivalves and have a fossil record extending to the late Silurian. The relationship between lucinid hosts and endosymbionts is inferred to have existed since at least the Jurassic based on habitat associations (occurrence at hydrocarbon seeps). Our understanding of the evolutionary relationships among lucinids and their relationships with endosymbionts is limited, however, as modern lucinid phylogenies are primarily derived from sequence data and are, therefore, limited to extant taxa. In order to fully understand the rich evolutionary history of lucinids, fossil taxa must be incorporated into analyses and, thus, the phylogenetic signal of conchological traits needs to be tested. This dissertation examines how lucinid shell morphology, as described by categorical character states and geometric morphometrics, corresponds with molecular phylogenies and endosymbiont diversity at several scales. Chapter 1 examines congruence and resolution in molecular tress versus trees based on categorical shell character states. A matrix of 58 shell characters and 52 species of lucinids from the Neogene and Quaternary of the Western Atlantic was used to construct morphological cladograms that were compared to published molecular phylogenies. Results indicate that cladograms based on shell characters are often congruent with molecular phylogenies at the genus-level, but are poorly resolved at more basal nodes. Nonetheless, the inclusion of shell characters provides a means to include extinct taxa in phylogenetic analyses. Chapter 2 further examines morphological and phylogenetic relationships using geometric morphometric analyses of shell interiors of eight lucinid species to test for phylogenetic signal in shape based on a landmark configuration focused on adductor muscle scars and shell outline. Results confirm a strong phylogenetic signal in landmark data, however, this signal does not represent shape variation for any particular morphologic feature(s). Finally, in Chapter 3, population-level host molecular phylogeny, host shell morphology (geometric morphometrics), and gill-associated bacterial relative abundances are compared in Ctena n. sp. occurring in anchialine ponds and coastal lagoons of San Salvador Island, the Bahamas as well as in Ctena orbiculata from coastal Florida and lagoons of San Salvador Island, the Bahamas. No significant differences in sequence data among populations were found, although there were differences in both host shell morphology and gill-associated bacterial relative abundance by locality, whereas host shell morphology and gill-associated bacterial relative abundance were not significantly correlated. This dissertation provides 1) a new phylogeny for lucinids incorporating morphological characters, 2) the first used of COI in a molecular phylogeny for the family, 3) the first test for phylogenetic signal in lucinid morphology, 4) the first test of a relationship between host morphology and gill-associated bacterial relative abundance, and 5) a description of and justification for a new lucinid species of Ctena.

This book was released on 2018-02-19 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from General Evolutionary Patterns and the System of the Class Bivalvia Food gathering by means of the labial palps restricted the radiation of the Protobranchia. Most members of this superorder (order Nuculida) preserved features characteristic of mobile Bivalvia-an oval or anterior - posteriorly lengthened shell, a mobile foot with a flat sole, 2 adductor muscles, a nuculoid hinge con sisting of chevron-shaped teeth which grow in size in front of and behind the umbo, and primitive double ctenidia with lamellae directed centrally from the axis. The labial palps-the main food gathering organ - and the ligament primarily undergo changes. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Hypotheses concerning long and short term factors influencing the coast-wide distribution of the bivalve fauna are formulated and examined. Consideration is given to global effects of plate tectonics, continental displacement and environmental factors. Ordination and clustering techniques are used to examine the size and distribution of zoogeographic provinces. Provincial boundaries are presented and the characteristics of these provinces are described.

Available in PDF, EPUB and Kindle. Book excerpt: This book identifies all valid species belonging to the superfamily Mactroidea living in American waters, distributed across fourteen biogeographical provinces. It also provides an updated classification of the widely occurring Mactroidea superfamily, which comprises eight subfamilies grouped into four families: Mactridae (Lamarck, 1809); Anatinellidae (Deshayes, J.Gray 1853); Cardiliidae (Fischer, 1887) and Mesodesmatidae (J. Gray, 1840). The species included in this superfamily are known to have existed in North America since the Early Cretaceous.
