Malaria-carrying mosquitoes nearly disappear in the dry season, yet they reappear suddenly following the first rains; using surveys of mosquito densities, the authors characterize the population ...

A lesser siren (Siren intermedia) may burrow into the bottom of its drying pond and aestivate for several weeks to more than a year. During aestivation it secretes a mucous cocoon, its, oxygen ...

Aestivation is an adaptation for survival in high temperatures or drought conditions. It is used as a method to stop desiccation (drying out) of the animal. Aestivation is common in invertebrates ...

We examined burrow microclimate and cocoon formation of the burrowing frog, Cyclorana australis, from northern Australia, during the dormancy season by monitoring frogs in burrows in the field. At the ...

If aestivation is common to this species of mosquito, it opens new possibilities for ways that malaria can be controlled. It may be possible to eradicate populations while they are dormant as the ...
