Temporary Pools

Paragraph 1: Temporary pools are freshwater habitats that retain water for only three to four months of the year or even shorter periods: typically for some eight or nine months they are dry basins without surface water. At the latitude of Canada’s southern Ontario, for example, the basin of a typical temporary pool fills with water when the snow melts in March and April. Because temporary pools (by definition) have neither a surface inlet nor outlet, the water steadily recedes through evaporation and seepage into the surrounding soil, disappearing altogether from the surface in June or July. Most of the animal residents one sees in temporary pools are aquatic insects such as caddis flies, whose larvae (wingless, immature insects) are sometimes the most conspicuous【Q1】 animals in these communities.
