In the mid‐twentieth century, many lakes near Sudbury, Canada, were severely
contaminated by acid and metal emissions from local smelters. For example, in the early …

Fossil cladoceran remains preserved in surface sediment samples from 44 oligotrophic
lakes in south-central Ontario were examined to evaluate the relationships between species …

Identifying thresholds of biotic community change along stressor gradients may be useful to
both ecologists and lake managers; however, there are several weaknesses in the …

Previous studies have suggested that the occurrence of larval Chaoborus in lakes may be
affected by fish predation, pH, elevation, temperature, nutrient level, water transparency and …

ABSTRACT Zooplankton communities in Boreal Shield lakes of south-central Ontario,
