STEYERMARK, A.C*; DIAMOND, J.: Optimal design of the digestive system Case studies in physiology and anatomy suggest that the design of cells, tissues, and organs is quantitatively adjusted to functional needs, such that the body uses available materials and space efficiently. Here we examine the capacity of the intestine and other organs for processing glucose. […]

REIBER, Carl L.: Ontogeny of oxygen sensitivity in crayfish: Peripheral oxygen receptors and cardiorespiratory modulation Crayfish embryos respond to reductions in water O2 at very early stages of development (stage XII). Heart rate, stroke volume and cardiac output decrease in response to hypoxic exposure at or below 40 mmHg O2 in stage XIII. This response […]

ATWATER, D Z; FAUTIN, D G: Online biographical database of taxonomists of sea anemones As part of a taxonomic database of sea anemones, I am developing a module dedicated to anemone taxonomists. Most of those taxonomists are now dead. I am gathering anecdotes about and biographies of them through library research and contact with people […]

DIOGO, Rui*; WAGEMANS, France; PARMENTIER, Eric; VANDEWALLE, Pierre; CHARDON, Michel: On the Homologies and Nomenclature of the Different Adductor Mandibulae Sections in Teleostean Fishes, with special regard to Catfishes The adductor mandibulae complex has been a subject of discussion and uncertainties due to a wide range of differentations and fusions that have occurred during teleost […]

GAINEY, JR., L.F.* ; WALTON, J.; GREENBERG, M.J.: Neuromuscular anatomy of clam gills The eulamellibranch gills of Mercenaria mercenaria contain three separate groups of muscles. Each gill filament has dorso-ventral muscle fibers running down its center. The interfilament tissue junctions, which connect adjacent gill filaments, contain longitudinal muscle fibers that run the length of the […]

DOELLER, Jeannette E.*; KRAUS, David W.: Mussel Gill Mitochondria Oxidize Sulfide in the Absence of Oxygen Geukensia demissa, the ribbed mussel, inhabits marine sulfidic sediments. Ciliated gills form the interface between animal and environment, encountering millimolar concentrations of sulfide along with low oxygen. Gill energy metabolism has been described as chemolithoheterotrophic, indicating that energy but […]

MEDLER, S; MULDER, EP; CHANG, ES; MYKLES, DL: Muscle fiber-type switching in the developing lobster claw: timing during the intermolt cycle During the larval and early juvenile stages of the American lobster, Homarus americanus, the claw closer muscles are identical, each being composed of a central core of fast muscle fibers surrounded by slow fibers. […]

MCHUGH, Damhnait: Molecular phylogenetic analyses indicate a rapid radiation of polychaete annelids The phylogenetic relationships of terebellidan and sabellidan polychaete annelids were investigated using elongation factor-1alpha (EF-1alpha) sequences alone and in combination with previously published data for three other genes. Forty-three ingroup taxa were sampled, including representatives of the Terebellidae, Ampharetidae, Alvinellidae, Pectinariidae, Trichobranchidae, Flabelligeridae, […]

WILSON, M. M.*; TURNER, R. L.: Mode of Reproduction and Genetic Structure of the Brooding Hermaphroditic Sea Cucumber Synaptula hydriformis Using Randomly Amplified Polymorphic DNA The viviparous sea cucumber Synaptula hydriformis is a simultaneous hermaphrodite that maintains multiple broods within the perivisceral coelom. It is an epiphytic species that clings to drift macroalgae, fleshy and […]

PROESTOU, D.A.: Microsatellite Markers Developed to Assess Paternity in Crepidula fornicata Estimates of reproductive success are crucial for understanding the evolution and timing of sex change. In polyandrous species, individual male reproductive success can only be quantified through paternity analysis. Paternity analysis requires the development of polymorphic molecular markers. I constructed a partial genomic DNA […]
