Inorganic ions in cold-hardiness
Cryobiology, 2004Cold exposure and freezing may affect ion distribution in several ways and reduce physiologically important ionic gradients. Both freeze-avoiding and freeze-tolerant organisms have developed mechanisms to handle this stress. Supercooled insects seem to be able to maintain their ionic gradients even at temperatures far below zero.

The scorpion Centruroides vittatus is periodically exposed to freezing temperatures in its natural habitat. It survives such stress by employing physiological mechanisms characteristic of the freeze-tolerant survival strategy used by some insects.

Understanding plant cold hardiness: an opinion
Physiologia Plantarum, 2012How plants adapt to freezing temperatures and acclimate to survive the formation of ice within their tissues has been a subject of study for botanists and plant scientists since the latter part of the 19th century. In recent years, there has been an explosion of information on this topic and molecular biology has provided new and exciting opportunities

Cold hardiness in the scorpion, Paruroctonus aquilonalis
Cryobiology, 1976Abstract Lower lethal temperatures represented by supercooling points were measured for the scorpion Paruroctonus aquilonalis (Stahnke) following exposure to laboratory regimes of photoperiod and temperature, as well as to ambient conditions. Analyses for the presence of glycerol and sorbitol in hemolymph, and of body water content were also ...

Physiology of cold hardiness in earthworms
Comparative Biochemistry and Physiology Part A: Physiology, 1996Abstract Physiological, biochemical and behavioral mechanisms involved in the winter survival of earthworms and earthworm cocoons are reviewed. Overwintering strategies of cold hardy invertebrates are commonly divided into two groups. In freeze-avoiding animals, ice formation in the tissues is lethal and winter survival is dependent on prolonged and ...

COLD HARDINESS IN HEXAPLOID TRITICALE
Canadian Journal of Plant Science, 1985The excellent cold hardiness of rye (Secale cereale L.) makes it a potential source of genetic variability for the improvement of this character in related species. However, when rye is combined with common wheat (Triticum aestivum L.) to produce octaploid triticale (X Triticosecale Wittmack, ABDR genomes), the superior rye cold hardiness is not ...

Cold Hardiness and Seed Shape in Maize
Nature, 1949AT least one mid-Western seed company has asserted that 'round-grade' dent corn (maize) seeds withstand more than 'flat-grade' seeds the cold weather after early spring sowings.

In both eggs and larvae of Hemerocampa lencostigma Smith and Abbot, cold hardiness can be expressed by the equation T1 = K1/Ha where T1 = survival temperature in degrees centigrade (or cold hardiness to the intensity factor). Ha = absolute humidity in millimeters of vapor pressure.

Cold hardiness in invertebrate poikilotherms
Comparative Biochemistry and Physiology Part A: Physiology, 1982Abstract 1. 1. A selective review is made of the information on cold hardiness in the following taxonomic groups: Protozoa, Platyhelminthes, Rhynchocoela, Rotifera, Nematoda, Mollusca, Annelida, Tardigrada, micro-Arthropoda (Collembola & Acari) and Arthropoda. 2. 2.
