Their phytopolyphagous diet, perfect adaptability to extreme cold and hot environments by way of aestivation
(h) coupled with high reproductive efficiency make this species cosmopolitan in distribution .
and ionic regulation in two species of Pomacea (Gastropoda, Prosobranchia).
Therefore, snails living under Mediterranean climates, characterized by dry and hot summers, prepare themselves as early as May to undergo a long aestivation
that is essential to their survival.
However, other remains are due to mortality during hibernation or aestivation
in the cave, as in the case of bats (Sevilla, 1986), or to human commensalism (Pokines, 1998; Eastham, 1995).
The earthworm's annual cycle is markedly seasonal, with an aestivation
period throughout the driest and coldest season of the year.
(summer diapause) in Hyperia postica (Coleoptera: Curculionidae), II.
This research suggests that short periods of dormancy, called aestivation
, in addition to burrowing behavior, may have been a crucial adaptation that allowed mammal ancestors to survive the P-T extinction.
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.
scorpioides also presents an aestivation
behavior during the dry season in the state of Maranhao, Brazil, when the animals bury themselves, presumably to avoid dehydration (Pereira et al.
Stievenart C Shell morphology, growth, reproduction and aestivation

After summer aestivation
, 14 wk after reinfestation and 22 wk after insecticide applications, only the control, horticultural oil, and Talstar treatments had hemlock woolly adelgid in our samples (Table 3).
