Ecology, Fishery and Aquaculture in Gulf of California, Mexico: Pen Shell Atrina Maura (Sowerby, 1835)
Chapter 1 Ecology, Fishery and Aquaculture in Gulf of California, Mexico: Pen Shell Atrina maura (Sowerby, 1835) Ruth Escamilla-Montes, Genaro Diarte-Plata, Antonio Luna-González, Jesús Arturo Fierro-Coronado, Héctor Manuel Esparza-Leal, Salvador Granados-Alcantar and César Arturo Ruiz-Verdugo Additional information is available at the end of the chapter http://dx.doi.org/10.5772/68135 Abstract The pen shell Atrina maura bears economic importance in northwest Mexico. This chapter considers a review on diverse ecology, fishery, and aquaculture topics of this species, car- ried out in northwest Mexico. In ecology, biology, abundance, spatial prospecting, sex ratio, size structure, reproductive cycle, first maturity sizes, variation of gonadosomatic indexes and growth are discussed. In fishery, the information analysed corresponds to the structure of the organisms in the banks susceptible to capture, institutional and ecologi- cal interaction for fishing regulation, evaluation of fishing effort, improvement in fishing performance using the knowledge and attitudes of the fishermen on fisheries policies in the Gulf of California, resilience and collapse of artisanal fisheries and public politics. In aquaculture, they are long-line culture, bottom culture, reproductive cycle, growth, pro- duction of larvae and seeds, biochemistry of oocytes, nutritional quality of the muscle, evaluation of diets based on microalgae, immunology in larval and juvenile and probi- otic use. The present work shows a status based on information published in theses and articles indexed 15 years ago to the date on the ecology, fishery and aquaculture in the pen shell Atrina maura carried out in the lagoon systems of northwest Mexico. Keywords: growth, reproduction, culture, immunology, populations, estuaries © 2017 The Author(s). -

Early Ontogeny of Jurassic Bakevelliids and Their Bearing on Bivalve Evolution
Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution NIKOLAUS MALCHUS Malchus, N. 2004. Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution. Acta Palaeontologica Polonica 49 (1): 85–110. Larval and earliest postlarval shells of Jurassic Bakevelliidae are described for the first time and some complementary data are given concerning larval shells of oysters and pinnids. Two new larval shell characters, a posterodorsal outlet and shell septum are described. The outlet is homologous to the posterodorsal notch of oysters and posterodorsal ridge of arcoids. It probably reflects the presence of the soft anatomical character post−anal tuft, which, among Pteriomorphia, was only known from oysters. A shell septum was so far only known from Cassianellidae, Lithiotidae, and the bakevelliid Kobayashites. A review of early ontogenetic shell characters strongly suggests a basal dichotomy within the Pterio− morphia separating taxa with opisthogyrate larval shells, such as most (or all?) Praecardioida, Pinnoida, Pterioida (Bakevelliidae, Cassianellidae, all living Pterioidea), and Ostreoida from all other groups. The Pinnidae appear to be closely related to the Pterioida, and the Bakevelliidae belong to the stem line of the Cassianellidae, Lithiotidae, Pterioidea, and Ostreoidea. The latter two superfamilies comprise a well constrained clade. These interpretations are con− sistent with recent phylogenetic hypotheses based on palaeontological and genetic (18S and 28S mtDNA) data. A more detailed phylogeny is hampered by the fact that many larval shell characters are rather ancient plesiomorphies. Key words: Bivalvia, Pteriomorphia, Bakevelliidae, larval shell, ontogeny, phylogeny.

The Quest for Natural Biogeographic Regions
Chapter 3 Carving up Australasia: the quest for natural biogeographic regions Most systematists will squirm at inferences derived from a non-monophyletic or artificial taxon. The importance of monophyly is critical to understanding the natural world and drawing inferences about past processes and events. Since the early 19th century, plant and animal geographers have also been concerned about correctly identifying natural areas. Plant geographer and taxonomist Augustin de Candolle tried to propose natural laws when proposing natural areas and failed. Humboldt abandoned natural classification and assigned vegetable forms, thereby creating a useful classification, which was unfortunately artificial. For early 19th century Australasian biogeographers, the concept of cladistic biogeography and area monophyly was decades away, while the importance of finding natural areas was immediate. Natural areas allowed the biogeographer to make inferences about the biotic evolution of a region such as Australia or New Zealand. Discovering the relationships between natural areas would allow for better inferences about dispersal pathways and evolutionary connections between continental floras and faunas, rather than proposing ephemeral land-bridges or sunken continents. Still, after 150 years of searching, biogeographers puzzle over the natural regions of Australasia. Why natural regions? As in biological systematics, artificial taxa represent a pastiche of distantly related taxa (think of the term ‘insectivores’, which would include all insect eating animals, such as funnel-web spiders, bee-eaters and echidnas). Artificial taxa are more closely related to other taxa than they are to themselves. The same is true for biogeography – artificial areas, such as ‘Australia’, are composites that are more closely related to other areas than they are to themselves. -
Chapter 18. Razor Fish and Scallops
Chapter 18. Razorfish and scallops CHAPTER 18. RAZOR FISH AND SCALLOPS ALAN BUTLER CSIRO Marine and Atmospheric Research, Hobart, Tasmania 7001. Email: [email protected] Figure 1. Razorfish Pinna bicolor near seagrass, Posidonia sp. The individual in foreground shows some recent, rapid growth at the posterior margin of the shell and an epifauna mainly of serpulids but with a gastropod, a few bryozoans, and a small colony of a didemnid ascidian beginning to overgrow the bryozoans. The shell in the background is dead, may have been there for a decade, and has a well-developed epifauna, mainly of bryozoans with a couple of sponge colonies. Introduction This chapter outlines some ecological studies of bivalve molluscs in Gulf St Vincent (GSV) waters. It is eclectic, not attempting to cover all studies of bivalves, but mainly those of several large species—the ‘razor fish’ Pinna bicolor, and the scallops Mimachlamys asperrima and Equichlamys bifrons—which are conspicuous, and have proven instructive not only for understanding the ecology of these sorts of animals (sessile filter-feeders, with broadcast spawning, external fertilisation and a long larval period), but of the dynamics of the Gulf ecosystem and of the relationships between species. A vast amount has been written about the ecology of bivalves worldwide (e.g. Wilbur & Yonge 1964- 1966; Bayne 1976; Yonge & Thompson 1976; Purchon 1977; Wilbur 1983-1988; Suchanek 1985; Ludbrook & Gowlett-Holmes 1989; Beesley et al. 1998), and no attempt is made to summarise it here. 238 Chapter 18.

Rare and Curious Specimens, an Illustrated
Having held the position in an acting capacity, Etheridge experienced no dif ficulty in assuming the full-time position of curator on 1 January 1895. He had, of course, to relinquish his half-time post in the Geological Survey but, as consulting palaeontologist to the Survey, he retained a foot in each camp and continued to publish under the aegis of both institutions. His scientific staff consisted of six men. Whitelegge was still active in his researches on marine invertebrates and was engaged in testing the efficiency of formalin as a preservative. North continued his studies on birds, but somewhat less actively since, to free Brazier for work on his long-delayed catalogue, he had been made responsible also for the ethnological, numismatic and historical collections. Conchology was now in the hands of Charles Hedley, first appointed in 1891 on a temporary basis to handle the routine matters of this department and to leave Brazier more time for his catalogue. Born in England, Hedley came to Australia at the age of twenty to seek relief from asthma and after a short period working on an oyster lease on Stradbroke Island, turned to fruit growing at Boyne Island. When a badly fractured left arm rendered him unfit for heavy work, he moved to Brisbane where, in 1889, he obtained a position on the staff of the Queensland Museum and developed an interest in shells. Finding that the collections and library of that insti tution were inadequate for his needs, he moved to Sydney and, within a few months, was recruited to the Museum at the age of thirty. -
Geomorphology and the Great Barrier Reef
Cambridge University Press 978-0-521-85302-6 - The Geomorphology of the Great Barrier Reef: Development, Diversity, and Change David Hopley, Scott G. Smithers and Kevin E. Parnell Excerpt More information 1 Geomorphology and the Great Barrier Reef 1.1 Introduction The Great Barrier Reef (GBR) is the largest coral reef system in the world. It extends from 248 300 S in the south to 98 300 S in the north, a distance of about 2300 km along the north-east shelf of Australia (Fig. 1.1). Accurate estimates of dimensions and other geographical data are available only for the Great Barrier Reef Marine Park (345 500 km2) or the Great Barrier Reef World Heritage Area (348 000 km2) which also includes islands excluded from the Park. Within this area are 2900 reefs occupying over 20 000 km2 or 9% of the 224 000 km2 shelf area (Hopley et al., 1989). However, this administrative area does not include the contiguous shelf of Torres Strait, data for which are more scant. The Strait is 150 km wide and east of the line of high islands, which link Australia to Papua New Guinea, the shelf has a width of over 200 km. Estimated total shelf area here is about 37 000 km2 and, relying on comparative data from the adjacent Great Barrier Reef Marine Park (which ends at 108 420 S) there may be a further 750 reefs and shoals with a total area of about 6000 km2. The GBR is also one of the best studied in the world. Although first described during James Cook’s voyage of exploration in 1770, because of science’s preoccupation with atolls, it did not become a major focus until after the establishment of the Great Barrier Reef Committee in 1922 and the ground-breaking year-long Royal Society Expedition to Low Isles near Cairns in 1928–29 (see below and Bowen and Bowen, 2002). -
