REICHMAN, J.R.; WILCOX, T.P.; VIZE, P.D.: Characterization and evolution of diverse peridinin chlorophyll-a protein gene families within symbiotic dinoflagellates. Photosynthetic dinoflagellates have evolved unique light harvesting complexes that combine the accessory pigment peridinin and chlorophyll-a within the hydrophobic center of water soluble proteins known as PCPs. PCPs allow the efficient harvesting of light in the […]

Trochophore larva is plesiomorphic for nemerteans evidence for prototroch in a basal nemertean Carinoma tremaphoros (Phylum Nemertea, Palaeonemertea)
MASLAKOVA, S. A. ; NORENBURG, J. L. : Trochophore larva is plesiomorphic for nemerteans: evidence for prototroch in a basal nemertean Carinoma tremaphoros (Phylum Nemertea, Palaeonemertea). Nemertean worms are spiralians displaying a variety of developmental modes, from encapsulated direct to indirect planktotrophic development with radical metamorphosis. The pilidium, a specialized planktotrophic larva, characterizes the order […]
How is an insect the size that it is How do physiological mechanisms change to produce genetic, environmental, and plasticity effects on body size
DAVIDOWITZ, G*; NIJHOUT, H.F.; D’AMICO, L.J.: How is an insect the size that it is? How do physiological mechanisms change to produce genetic, environmental, and plasticity effects on body size? Body size is one of the more important life history characters of many organisms; it is also well established that it is plastic. However, little […]
Evolution and habitat preference in Siboglinids (formerly Pogonophora)
HALANYCH, Kenneth M: Evolution and habitat preference in Siboglinids (formerly Pogonophora) Siboglinids, previously referred to as pogonophorans, are marine protostome worms which lack a functional gut and harbor endosymbiotic bacteria. Of the two major recognized clades, frenulates and vestimentiferans, the evolutionary history of the vestimentiferans is one of the best studied for any annelid. Recent […]
Consequences of communal egg-laying in the apple murex snail, Phyllonotus pomum
SWANSON, C.A.: Consequences of communal egg-laying in the apple murex snail, Phyllonotus pomum Communal egg-laying, the sharing of hard substrates by conspecifics for depositing clutches of egg capsules, is common among gastropod molluscs. The apple murex snail, Phyllonotus pomum, lays globular communal egg masses composed of clutches simultaneously deposited by 2-52 females. As mass volume […]
Biogeographic Patterns in Mode of Development in Marine Invertebrates
COLLIN, R.: Biogeographic Patterns in Mode of Development in Marine Invertebrates Latitudinal patterns in mode of development of molluscs in the North Eastern Atlantic were first demonstrated by Thorson in 1946. He demonstrated that planktotrophic development is more common at low latitudes than at higher latitudes. Since then, it has often been assumed that this […]
Amino acid metabolism in adult Lepidoptera from biochemistry to life history evolution
O’BRIEN, DM; FOGEL, ML; BOGGS, CL: Amino acid metabolism in adult Lepidoptera: from biochemistry to life history evolution. Adequate nutrition is critical to reproduction in animals. In many species, proteins are the nutrient in lowest supply and highest demand. This is particularly true in nectar feeding insects; e.g. Lepidoptera, in which protein provisioning takes place […]
Using adaptive habitat selection to predict future threats to biodiversity
MORRIS, D. W.*; KINGSTON, S. R.: Using adaptive habitat selection to predict future threats to biodiversity. We test an intriguing postulate. Can one use the adaptive selection of habitat by humans to forecast future threats to biodiversity? The answer appears to be yes. World Resources Institute (WRI) data demonstrate that humans select urban over rural […]
Near-shore vegetation responses to experimental flows in Grand Canyon
PORTER, Marianne/E; KEARSLEY, Mike: Near-shore vegetation responses to experimental flows in Grand Canyon We examine the responses of four clonal herbaceous species and a dominating exotic to a three-month experimental low steady flow on the Colorado River through Grand Canyon. Plant density, soil moisture, soil texture, and soil temperature data were collected on transects from […]
Exotic species and the decline of amphibians unintended consequences on a global scale
VREDENBURG, V T: Exotic species and the decline of amphibians: unintended consequences on a global scale. A puzzling aspect of amphibian declines is that amphibians, particularly frogs, have been declining even in large protected areas. These habitats are generally thought to be relatively unaltered and undisturbed. However, the introduction of nonnative fish is a common […]
