Abstract

Tadpoles of the Mallorcan midwife toad (Alytes muletensis) displayed a clear diel pattern of activity and microhabitat selection in torrent pools in Mallorca. Tadpoles spent much of the day foraging in a non-aggregated fashion in warm shallow areas, and activity peaked at 1700-1900 hr. In mid-afternoon, however, when much of the water surface was in direct sunlight, tadpoles moved away from the shallows and formed aggregations under rock overhangs at the sides of the pool. Both activity and tadpole density in the shallows dropped dramatically after dark, when there was a movement of the population back into deeper water or hiding places.
