Circadian and circannual behavioural rhythms of Helix are described in the field. Laboratory studies demonstrate the existence of an endogenous component for these rhythms. The effects of the environmental factors on the snail activities are multiple: light/dark and cold/warm cycles synchronise the behavioural rhythms; a masking effect is observed when it rains since the animals are active throughout the 24 h day; high temperature and low relative humidity cause a complete cessation of… 

Ecological Significance of Biological Clocks

Since the basic properties of biological time-keeping systems were formally determined at the Cold Spring Harbor symposium in 1960, the concept of the biological clock has become widely accepted and amenable to experimental investigation, and considerable progress has been made towards answering what was regarded as the most difficult question in chronobiology.

A comparison of the physiological responses of two land snail species with different distributional ranges

The seasonal patterns in biochemical tissue composition in relation to aspects of behavioural ecology in three land snail populations are examined, finding that the specialist and range-restricted H. figulina shows a constant and more predictable seasonal pattern, which may be effective for surviving in its historical biogeographic range, but it seems to be more vulnerable to possibly changing environmental conditions.

The Role of Microhabitat and Water Level in Regulating the Small-Scale Distribution, Seasonal Abundance and Overwintering Success of the Protected Snail Vertigo moulinsiana in a Natural Wetland

The results indicate that this V. moulinsiana population does not follow typical models constructed for vertebrates or other animals with high dispersal abilities, like the Ideal Free Distribution (IFD) model, and requires a specific approach.

Seasonally contrasting life-history strategies in the land snail Cornu aspersum: physiological and ecological implications

Compared in the laboratory the trade-offs in reproductive traits between early (after maturity) and delayed (after dormancy) reproduction in young land snails Cornu aspersum (Muller, 1774) (syn. Helix aspersa), depending on food energy content.

Physiological and biochemical responses to cold and drought in the rock-dwelling pulmonate snail, Chondrina avenacea

The seasonally highest levels of supercooling capacity and the highest tolerance to subzero temperatures were tightly linked to hibernation (diapause), and no accumulation of low-molecular weight compounds (potential cryoprotectants) was detected in hibernating snails except for small amounts of the end products of anaerobic metabolism.

Adaptive Changes in the Vestibular System of Land Snail to a 30-Day Spaceflight and Readaptation on Return to Earth

Despite the permanence of gravity, the land snail Helix lucorum responded in a compensatory manner to its loss and readapted once gravity was restored.

Habitat Use and Movement Patterns of the Endangered Land Snail Thersites mitchellae (Cox, 1864) (Camaenidae)

The results show that the probability of moving on a night, and the nightly distance moved once active both increase with increasing humidity up to a maximum and then decline.

Physiological, Diurnal and Stress-Related Variability of Cadmium-Metallothionein Gene Expression in Land Snails

Investigating the physiological and diurnal variability of CdMT gene expression in snails exposed to Cd and non-metallic stressors such as desiccation and oxygen depletion concluded that factors increasing MT expression variability have to be considered when using MT mRNA quantification as a biomarker for environmental stressors.

The reproductive response of Cornu aspersum to different hibernation conditions

ABSTRACT This study was conducted between February and May 2019 on mature Cornu aspersum in the Black Sea region, Turkey to investigate the effects of different hibernation situations on reproductive



Circannual and circadian rhythms in the snailHelix aspersa Müller and the photoperiodic control of annual activity and reproduction

Individual adultHelix aspersa show a circadian rhythm of locomotor activity when kept in constant darkness, temperature, and high humidity and exhibited a circannual cycle of movement, feeding, and reproductive activities which was faster than the normal annual cycle.

Keeping an eye on retinal clocks.

As a highly organized and accessible tissue, the retina is particularly well suited for the study of the input-output pathways and the mechanism for rhythm generation, as researchers apply new molecular techniques toward looking into the eye's clock.

Circadian Rhythm of Optic Nerve Impulses Recorded in Darkness from Isolated Eye of Aplysia

The isolated eye of the sea hare Aplysia califomica shows a circadian rhythm of optic nerve impulses when kept in total darkness, which provides a quantized output with an ideal control for studies on rhythms.

The consequences of eye removal for the circadian rhythm of behavioral activity inAplysia

The eye is neither the only photoreceptor nor the only circadian oscillator coupled to the locomotor rhythm, but it is reasonable to believe that the eye is one among several endogenous oscillators coupled to locomotion.

The dependence of thermopreferendum in Helix pomatia L. on air temperature.

Behavior of SCN-Lesioned Chipmunks in Natural Habitat: A Pilot Study

Lack of major differences may be attributable to the exceptionally favorable conditions for survival such as a veryabundant fallacorn crop, medium population size, and absence of heavy predation.


The sea slug, Aplysia, is a useful model system for research on the neurophysiology of circadian integration and there is no evidence yet for hormonal coupling between photoreceptors and oscillators or between oscillators and rhythmic outputs.

Elements of cold hardiness in a littoral population of the land snail Helix aspersa (Gastropoda: Pulmonata)

It appeared that there was not a real cold-hardiness strategy in this population; rather a sum of parameters, varying in consequences of the external conditions and of the activity cycle, which are responsible for the enhancement of the supercooling ability during winter.

Patterns of dispersion, density and dispersal in alpine populations of the land snail Arianta arbustorum (L.) (Helicidae)

In studying populations of the land snail Arianta arbustorum in the eastern Swiss Alps, juvenile and subadult snails were found to be aggregated all the time, while adults were mostly aggregated during summer, the main mating period, while the intensity of aggregations was influenced by weather conditions.
