    Blue through UV polarization sensitivities in insects

    A Signal-to-Noise optimization model has now been extended to explain the range of species-specific polarization sensitivities of insects. The different polarization sensitivities are shown to represent optimi...

    Time Scale Variations of Estuarine Stratification Parameters and Impact on the Food Chains of the Chesapeake Bay

    There are three basic premises in this paper. One is that many species which utilize estuarine waters during part or all of their life cycle stages represent successful specific food chains for which the growt...

    Induced chemiluminescence of oxidized fatty acids and oils

    The injection of a strong organic base into milligram quantities of fats and oils dissolved in methylene chloride results in a burst of chemiluminescence whose peak intensity is a function of the previous ther...

    The transport of oyster larvae in an estuary

    Vertical and horizontal distributions of 3 larval stages of the oyster Crassostrea virginica were measured concurrently with phytoplankton species compositions, phytoplankton size distributions and physical hydro...

    Light-shade adaptation by the oceanic dinoflagellates Pyrocystis noctiluca and P. fusiformis

    Species-specific rates of photosynthetic carbon uptake (P), chlorophyll a content and P versus irradiance (P-I), have been measured for cells of Pyrocystis noctiluca and P. fusiformis isolated from natural popula...

    Phytoplankton patchiness and frontal regions

    In the Chesapeake Bay estuary there are persistent seasonal frontal and interfrontal regions that serve to deliver and retain different phytoplankton populations. The “patchiness” of phytoplankton, both in tot...

    Inorganic carbon requirements of natural populations and laboratory cultures of some Chesapeake Bay phytoplankton

    The rates of photosynthetic carbon fixation for some natural populations of Chesapeake Bay phytoplankton and for unialgal cultures of species isolated from those populations follow hyperbolic saturation kineti...

    Phytoplankton cages for the measurementin situ of the growth rates of mixed natural populations

    We have designed and tested phytoplankton “cages” in which captured natural populations can be re-suspendedin situ at their original site or at different sites. The “bars” of the cage consist of a membrane whose ...

    Chemical Production of Excited States: Adventitious Biological Chemiluminescence of Carcinogenic Polycyclic Aromatic Hydrocarbons

    The chemical production of electronically excited states in biological systems falls into several categories. The first and most prominent is Bioluminescence, a late evolutionary selection for “luciferase”-cat...

    Some limitations of thein vivo fluorescence technique

    Thein vivo chlorophylla fluorescence technique for phytoplankton depends on the effective absorption and fluorescence quantum yield of chlorophylla. The range of variation in the ratio ofin vivo fluorescence: ext...

    Growth and dissipation of phytoplankton in Chesapeake Bay. II. A statistical analysis of phytoplankton standing crops in the Rhode and West Rivers and an adjacent section of the Chesapeake Bay

    It is possible to make statistically significant comparative measurements of similar sections of subestuaries under conditions where the large natural variations would mask all but drastic changes in the syste...

    Applications of Bioluminescence and Chemiluminescence

    Chemiluminescence (bioluminescence) arises from the excited states of products of an exothermic reaction. It is analogous to photoluminescence in that the individual excited molecular species are not in therma...

    Growth and dissipation of phytoplankton in Chesapeake Bay. I. Response to a large pulse of rainfall

    Approximately 90 Km2 of Chesapeake Bay contiguous with the Severn, South, Rhode and West Rivers were surveyed by in vivo chlorophyll fluorescence and captured samples following a large pulse of rainfall in summer...
