The shallow water benthic habitat of the SW Beaufort Sea is frequently
gouged by the keels of ice pressure ridges. This natural physical
disturbance was hypothesized to be an important factor affecting the
structure of the benthic community. Smith-McIntyre grab samples were
taken from three discrete gouge axes and from...
Nucleic acid estimates in tissues of marine macrophytes with the fluorochromes Hoechst 33258 and ethidium homodimer were severely impaired by high concentrations of interfering compounds. The isolation and extraction techniques used pointed towards compounds of low molecular weight and of polar characteristics that were insensitive to organic solvent extraction and...
