A shorter 30-day experiment was conducted to investigate the relationship between the size of the animals and the rate of water loss during aestivation
. Wild-caught snails (n = 150), ranging from 5 to 138 g (shell height 15-63 mm), aestivating in air were weighed daily for 1 month.
was the target of many studies, hence lots of aspects of its physiology and biochemistry were elucidated, notably for the animal groups-anuran amphibians and pulmonate land snails .
: valvate = 0; convolute/contorte = 1; imbricate/quincuncial = 2.
The diameters of the aestivation
chambers and subterranean galleries were also measured when present.
Morphology and aestivation
behaviour in some Madagascan acavid snails.
In his Flora Franciscana (Greene, 1891) he placed this unique species in a special group of the genus Streptanthus characterized by "Calyx very irregular, the uppermost sepal greatly enlarged, in aestivation
conduplicate over the others".
Income breeding allows an aquatic snake Seminatrix pygaea to reproduce normally following prolonged drought-induced aestivation
While there was variation in techniques among the studies we reviewed, all surveys were conducted during peak activity periods, between movement from terrestrial aestivation
and overwintering areas to aquatic habitats (generally during the last 2 weeks of April), and during the return to aestivation
, usually about the second and third week of July.
A number of studies have recorded periods of inactivity, classified as aestivation
, in freshwater chelonians (Bury 1979, Litzgus et al.

In Mexico, Kinosternon leucostomum individuals occupying a temporary lake were reported to travel distances of up to 600 m to nesting and aestivation
sites (Morales-Verdeja & Vogt 1997).
