Gene fusions and gene duplications : relevance to genomic annotation and functional analysis
(BioMed Central, 2005-03-09)
Background: Escherichia coli a model organism provides information for annotation of other genomes. Our analysis of its genome has shown that proteins encoded by fused genes need special attention. Such composite ...
Long-term survival of adult Arctic grayling (Thymallus arcticus) in the Kuparuk River, Alaska
(National Research Council Canada, 2004-12-23)
In many long-lived species such as Arctic grayling (Thymallus arcticus), population growth rate is most sensitive to changes in adult survival probabilities. Understanding the factors that regulate adult survival in this ...
Rotifers as experimental tools for investigating aging
(Taylor & Francis, 2014-06-12)
Comparative biogerontology has much to contribute to the study of aging. A broad range of aging rates have evolved to meet environmental challenges, and understanding these adaptations can produce valuable insights into ...
The savory swimmer swims north : a northern range extension of the blue crab Callinectes sapidus?
Worldwide, climate-change is shifting species distributions poleward. Here I present recent (2012-2014) observations of the blue crab, Callinectes sapidus, in the Gulf of Maine (GoM), north of its historical range of Cape ...
Microbial biogeography along an estuarine salinity gradient : combined influences of bacterial growth and residence time
(American Society for Microbiology, 2004-03)
Shifts in bacterioplankton community composition along the salinity gradient of the Parker River estuary and Plum Island Sound, in northeastern Massachusetts, were related to residence time and bacterial community doubling ...
Fiddler on the roof : a northern range extension for the marsh fiddler crab Uca pugnax
A northern range extension is presented here for the marsh fiddler crab Uca pugnax. In summer 2014, adult crabs were found as far north as Hampton, New Hampshire (42.924428, -70.820517), which is 80 km north of its previously ...
Presynaptic nanodomains : a tale of two synapses
(Frontiers Media, 2015-01-26)
Here we summarize the evidence from two “giant” presynaptic terminals—the squid giant synapse and the mammalian calyx of Held—supporting the involvement of nanodomain calcium signals in triggering of neurotransmitter ...
Effects of preservation methods of muscle tissue from upper-trophic level reef fishes on stable isotope values (δ13C and δ15N)
Research that uses stable isotope analysis often involves a delay between sample collection in the field and laboratory processing, therefore requiring preservation to prevent or reduce tissue degradation and associated ...
Catecholaminergic connectivity to the inner ear, central auditory, and vocal motor circuitry in the plainfin midshipman fish porichthys notatus
Although the neuroanatomical distribution of catecholaminergic (CA) neurons has been well documented across all vertebrate classes, few studies have examined CA connectivity to physiologically and anatomically identified ...
