Shell Repair Frequencies in New Jersey Bivalves: A Recent Baseline for Tests of Escalation with Tertiary, Mid-Atlantic Congeners

Abstract: Articulated and disarticulated shells of Anadara ovalis, Anomia simplex, Argopecten irradians, Astarte castanea, Crassostrea virginica, Divalinga quadrisulcata, Donax variabilis, Ensis directus, Geukensia demissa, Mercenaria mercenaria, Mya arenaria, Mytilus edulis, Petricola pholadiformis, Spisula solidissima, and Tagelus plebeius collected from New Jersey intertidal life and death assemblages were measured, and the frequency, type (scalloped, divoted, cleft, embayed), location (ventral, anterior, posterior), and shell size at inception of repair determined. Repair frequency ranges from zero (D. quadrisulcata) to 0.30 (M. arenaria). Size refuge from sublethal breakage was attained by S. solidissima and C. virginica. Posterior repairs necessitated by siphon-nipping characterize M. mercenaria and E. directus. Ventral repairs associate with species subjected to valve-wedging (S. solidissima, M. mercenaria) or with ventral egress of the foot (A. ovalis). Ventral repairs among deep infaunal clams (M....

A new species of Borealosuchus (Crocodyliformes, Eusuchia) from the Late Cretaceous–early Paleogene of New Jersey

Abstract: A lower jaw and associated postcranial remains from the Late Cretaceous–early Paleocene Hornerstown Formation of New Jersey form the basis of a new crocodyliform species, Borealosuchus threeensis. Although one of the oldest known species of Borealosuchus, phylogenetic analysis supports a closer relationship to Borealosuchus from the early Eocene than with other Late Cretaceous or early Paleocene forms. This is based on the shared presence of a short mandibular symphysis excluding the splenial, a small external mandibular fenestra, and ventral osteoderms composed of two sutured ossifications. It is also similar to Borealosuchus material from the Paleocene of western Texas, though conspecificity cannot be demonstrated at present. A close relationship with the basal alligatoroids Leidyosuchus or Diplocynodontinae is not supported. The distribution of lower jaws with very small slit-like external mandibular fenestrae, or no fenestrae at all, among basal crocodylian lineages (including Borealosuchus) ...

Women Seeking Health Information : Distinguishing the Web User

Abstract: Given the advantages of using the Web for health information-seeking and a survey result that women are more likely to use the Web as a channel to locate health information, the authors explored the health information-seeking process and behavior of women who use the Web to seek such information. Although based on previously collected data, this article represents an extension of the earlier analysis with its focus on women who, at least to some extent, seek health care information via The Web (herein, Web user), a topic not thoroughly addressed in the earlier study. A comparison of female Web users and non-Web users who seek health information revealed that Web users sought health information at a higher rate than non-Web users. Web users were more likely to communicate with medical professionals about the health information found and claimed that their decisions about health treatments were influenced by the health information. In most cases, Web users expressed a higher awareness of resources, regardle...

Circadian Clock-Controlled Regulation of cGMP-Protein Kinase G in the Nocturnal Domain

Abstract: The suprachiasmatic nucleus (SCN) circadian clock exhibits a recurrent series of dynamic cellular states, characterized by the ability of exogenous signals to activate defined kinases that alter clock time. To explore potential relationships between kinase activation by exogenous signals and endogenous control mechanisms, we examined clock-controlled protein kinase G (PKG) regulation in the mammalian SCN. Signaling via the cGMP‐PKG pathway is required for light- or glutamate (GLU)-induced phase advance in late night. Spontaneous cGMP‐PKG activation occurred at the end of subjective night in free-running SCN in vitro. Phasing of the SCN rhythm in vitro was delayed by 3 hr after treatment with guanylyl cyclase (GC) inhibitors, PKG inhibition, or antisense oligodeoxynucleotide (ODN) specific for PKG, but not PKA inhibitor or mismatched ODN. This sensitivity to GC‐PKG inhibition was limited to the same 2 hr time window demarcated by clock-controlled activation of cGMP‐PKG. Inhibition of the cGMP‐PKG pathway at this time caused delays in the phasing of four endogenous rhythms: wheel-running activity, neuronal activity, cGMP, and Per1. Timing of the cGMP‐PKGnecessary window in both rat and mouse depended on clock phase, established by the antecedent light/dark cycle rather than solar time. Because behavioral, neurophysiological, biochemical, and molecular rhythms showed the same temporal sensitivities and qualitative responses, we predict that clock-regulated GC‐ cGMP‐PKG activation may provide a necessary cue as to clock state at the end of the nocturnal domain. Because sensitivity to phase advance by light‐GLU-activated GC‐ cGMP‐PKG occurs in juxtaposition, these signals may induce a premature shift to this PKG-necessary clock state.
