A list of known metabolites of this group of fungi has been assembled and the common physical propenies of these compounds are given when they have been reported. Such data as have been published on the toxicity of these metabolites is summarised, with particular emphasis on suitable review articles. An attempt is made to provide a comprehensive list of agents, known as potential inhibitors of the growth of these fungi.Item Open Access Lake classification in Nova Scotia from phosphorous loading, transparency and hypolimnetic oxygen consumption(Dalhousie Printing Centre, 1986) Schwartz, P. Y.; Underwood, J. K.; Nova Scotian Institute of ScienceThree indices of eutrophication are used to compare effects of urbanization on seven headwater lakes near Halifax, Nova Scotia. Annual (1983) inputs of phosphorus were calculated and compared with lake Secchi transparencies and rates of consumption of hypolimnetic oxygen (Thienemann index). Results from transparency and oxygen deficits were similar but implied greater eutrophication than did the phosphorus index. Brief discussion of some inherent problems of each index is included.Item Open Access Distribution and abundance of mysids in the Cumberland Basin, upper Bay of Fundy(Dalhousie Printing Centre, 1986) Prouse, N. J.; Nova Scotian Institute of ScienceThe distribution and abundance of two species of mysids, Neomysis americana and Mysis stenolepis, in the Cumberland Basin was studied on monthly cruises from March to October 1981 and 1982. Maximum numbers and biomass occurred in summer and ea rly fall respecti ve ly, with lower values in March and October. N. americana was the dominant species, ave raging up to 10 adults m·•; this species produced two generations per year, the first in May-June and the second overwintering generation in September-October. M. stenolepis produced one generation per year in May-June. Despite high turbidity and tidal currents, adult M. stenolepis demonstrated limited vertical migration, with greater numbers observed in the upper 2m at night than in daylight hours. Spartina detritus was present in the gut of mysids t hroughout the study and suspended in the water at concentrations t ha t potentially could support the mysid populations.
