Sympatric occurrence of Eubranchiopoda in ephemeral pools: A comment

Debrey et al. (1991) observed what they thought was the atypical occurrence of three species of Eubranchiopoda, each belonging to a different order in a vernal prairie pond in southeastern Wyoming. Co-occurrence of Eubranchiopoda in ephemeral pools is not unusual. Evidence of multi-species temporary pool communities is presented, along with a brief discussion of what may structure ephermeral pond communities.
