    Notes:
    We have performed uniaxial stress measurements on the 1Eg,1T2g, and 3Eg excited states of NaF:Cu+. Stress was applied along the [001] axis producing a tetragonal and a hydrostatic strain. From the tetragonal splitting, we have determined the Jahn–Teller energy in the 1Eg state to be 320 cm−1 thus supporting the recent reassignment of the states of Eg symmetry in this system [J. M. Berg and D. S. McClure, J. Chem. Phys. 90, 3915 (1989)].

    Notes:
    This study examined the effects of competition on the growth of Avena fatua, winter wheat and winter barley. Plants were sampled at frequent intervals from replacement series experiments at two contrasting sites in the U.K. A. fatua was much slower to establish than the two cereals, but thereafter exhibited a faster rate of growth. In monoculture, it took a considerable time for A. fatua to reach a size equal to that of the cereals, but by the end of the experiments it was the largest of the three species. The change-over from cereal dominance in mixtures to A. fatua tiominance was rapid, and in three cases coincided with cereal flag leaf emergence. In the fourth case, it appeared to coincide with the art of canopy height extension. At one site the rder of competitiveness at anthesis was A. fatua= barley〉wheat, and at the other site the order was A. fatua〉wheat〉barley. In order to explain and predict differences between years and sites, more studies are required on morphological development in relation to abiotic variables.

    Abstract To test if the high nutrient inputs of agroeosystems select for specialized agroecotypes or for phenotypic plasticity, Ontario populations of the northwardly migrating annual weed Solanum ptycanthum from ruderal (beach) and agricultural habitats were compared over a nutrient gradient. Temporal variation of total available nitrogen was determined in both types of habitats. As gene flow via seed contamination of tomato transplants from S. United States was detected, variation in response to nutrient (N) levels was also compared between agrestal populations from the northern (Ontario) and southern (Georgia) ends of the species range. Five families from six populations (two northern agrestal, two northern ruderal and two southern agrestal) were grown in the greenhouse at low, medium and high nutrient levels, and plant growth and traits associated with reproductive success measured. All populations displayed significant levels of plasticity in the majority of vegetative and reproductive traits. There were no detectable differences over the levels of nutrients tested between individuals sampled from northern agrestal and ruderal populations, even though variation in available nitrogen is greater in agroecosystems. Southern agrestal populations were genetically differentiated from the northern populations, and exhibited almost twice the overall plasticity of northern populations, measured by the Mahalanobis distance. Canonical discriminant analysis showed complete overlap in the northern populations over all nutrient levels, suggesting that colonization of new habitats is via a general-purpose genotype, rather than by selection for specialized agroeotypes.

    Abstract Determination of the trace-elements Ba, Ce, La, Nb, Rb, Sr and Zr have been made on lavas from six trachytic and pantelleritic volcanoes in the Kenyan and Ethiopian Rifts. Consideration of these data shows that Ce, La, Nb and Zr have behaved as truly residual elements. In the peralkaline suites examined, plotting other chemical parameters against a residual-element such as Zr appears to be informative. The individual residual-element ratios are constant at any one volcano suggesting that the salic and basic lavas are geochemieally related and that the trachytes and pantellerites do not have an origin independent of the associated basalts. Different values of individual residual-element ratios characterize different groups of volcanic centres. In the northern part of the Kenyan Rift, progressive change in these ratios with time can be traced. In the salic lavas, Ba and Sr show patterns of extreme depletion relative to the alkali basalts and these data suggest that the salic rocks are the result of protracted crystal-fractionation. The relative volumes of the extruded lava-types are discussed and it is suggested that the trachytic and pantelleritic centres developed above cupolas of salic magma situated on top of a large basaltic reservoir. It is likely that the preponderance of salic rocks and the scarcity of lavas of intermediate composition are not criteria by which one can rule out an origin of differentiation by crystal-fractionation.

    Notes:
    Summary A 1983 human Mississippi isolate of eastern equine encephalomyelitis virus (EEEV), recently identified as an antigenic subtype of the North American variety, was genetically characterized using oligonucleotide fingerprinting and sequencing of viral RNA. This strain was found to be very closely related to other North American EEEV isolates from the same time period. Phylogenetic analysis suggested that this subtype belongs to a single EEEV lineage in North America. Two amino acid substitutions in the E 2 envelope glycoprotein, not seen in eight other isolates sequenced, probably contributed to the antigenic difference with respect to other EEEV strains. These substitutions include threonine for lysine at position 71, resulting in the addition of a potential N-linked glycosylation site, and lysine for glutamic acid at position 147.

    Notes:
    Abstract Zooplankton and phytoplankton communities were observed and recorded at Fire Island Inlet from 1971–1974. Species typical of a temperate, neritic environment were found. Sampling by net and bottle at several stations in the area revealed two populations, one representative of the bay water and the other representative of the ocean water. It was further found, by comparing frequency of occurrence relative abundance, rank order and indicator species, that these two populations could be monitored at one sampling station (Oak Beach) by sampling at the appropriate tidal intervals, i.e., midtide after slack current, on both the ebb and flow tides. Observations from one site of plankton communities representative of bay water and of ocean water, as they move into and out of the Inlet, could be of significance in monitoring the effects of proposed man-made changes in the environment. It is possible that other coastal areas could benefit by such a combined approach.
