- ... Analysis of extreme tides in the Bay of Fundy, Canada, for the period 1899—1971, coupled with field observations, indicates the presence of a complex of environmental variables. Extreme tides expose organisms to a variety of stresses depending upon the time of year and weather conditions; but, as both weather and tidal extremes are acylic relative to the life span of short—lived species, there is ...

- ... The most important source of organic detritus in Nova Scotia caves is feces of the porcupine, Erethizon dorsatum. The high organic content of this cave detritus supports a numerically rich microarthropod fauna, composed of epigean species preadapted to a troglic environment. The fauna is of recent, postglacial origin, and no troglobites were identified. Three distinct stages in detritus decomposit ...
