whose emergence from the deep burrow where they estivate
is stimulated by their seasonal rhythm of reproduction and by the vibrations and the sounds of thunder and large raindrops falling on the ground.
They lay their eggs on land, can estivate
several months out of water, and can digest cellulose (Rosenberg 1989), so the transition from living in cast-up vegetation in the intertidal zone to leaf litter on the forest floor might not have been difficult.
Furthermore, to maintain a positive energy balance, animal species that reside in ephemeral environments may estivate
or move to locations with more favorable conditions (Ligon and Peterson, 2002; Winne et al.
If temperature exceeds 80[degrees]F, hamsters estivate
and become very difficult to rouse.
Therefore, we suspect that frogs were not infested with larval mites in the vicinity of ponds in which they reproduce, but were infested in the shelters where they estivate
during the dry season.
