要旨:
The Neotropical mayfly Campsurus notatus, occurs abundantly in várzea lakes, requiring about
three months for its aquatic development. Contrary to other suggestions its aquatic instars are shown
to be sediment feeders. The nymphs burrow continuously in the loose sediment without building stable
tubes. This organism is therefore an important agent for bioturbation and consequently for chemical
exchange at the sediment/water interface.
