AT Finse, situated at 1,200 m above sea level in the mountain plateau of Hardangervidda, Norway, adult Pelophila borealis (Coleoptera, Carabidae) overwinter in the soil of a sedimentation flat1. During the winter the flat is periodically flooded by the adjacent river, and consequently covered by a layer of ice. Sixty to 120 cm of snow covers the ground from late September until early June. Soil temperatures at the beetle's overwintering sites are normally slightly below 0° C, but rarely drop… 
Adaptations to Alpine and Polar Environments in Insects and Other Terrestrial Arthropods
TLDR
This chapter mainly reviews the adaptation of terrestrial arthropods found beyond the limits of forests and focuses on the different factors that contribute to the overall adaptational strategies of different species.
Anaerobiosis in overwintering collembolans and oribatid mites from windswept mountain ridges.
TLDR
In the laboratory two species of oribatid mites from this habitat, Calyptozetes sarekensis (Trag.) and Carabodes labyrinthicus (Mich.) survived several weeks of anoxia at 0?C, some specimens for more than 96 d, and during anaerobiosis lactate was accumulated, which suggests that the formation of lactate in itself is not the only adaptation to survival under oxygen deficiency.

Survival of Immersion and Anoxia by Larval Tiger Beetles, Cicindela togata
TLDR
Tiger beetle larvae are physiologically capable of surviving several days of inundation during floods without mechanisms to prevent burrow flooding by entering a quiescent state and survive much longer periods of anoxia than has been previously reported for terrestrial insect larvae.
Immersion tolerance in rangeland grasshoppers (Orthoptera: Acrididae)
TLDR
Survition times indicate that mortality associated with seasonal rainfall is rarely caused by immersion, and the significant resistance to hypoxia by these grasshoppers is not strongly correlated with habitat association and may instead be correlated with life history traits associated with overwintering.
Cold Tolerance of Mountain Stoneflies (Plecoptera: Nemouridae) from the High Rocky Mountains
TLDR
Investigation of cold tolerance of several alpine stoneflies from the Rocky Mountains, USA indicates that high-elevation stoneflies at greater risk of freezing may have correspondingly lower SCPs, and despite their common association with glacial meltwater, they appear to be living near their lower thermal limits.
Life on the edge: insect ecology in arctic environments.
TLDR
The current focus of global climate change research on polar regions is identified, particularly the opportunity to study fundamental ecological processes and spatial dynamics in the relatively simple Arctic ecosystems.
Anoxia tolerance in high Arctic terrestrial microarthropods
Abstract.  1. Ten Arctic species of Collembola and two species of cryptostigmatic mites survived anoxia at 5 °C over periods ranging from 1 to 36 days.
Ecology of alpine carabid beetles ( Coleoptera , Carabidae ) in a Norwegian glacier foreland , with a special focus on claw wearing to indicate relative age
Nine species of carabid beetles (Coleoptera, Carabidae) were pitfall-trapped during two years in an alpine glacier foreland of southern Norway. A two-year (biennial) life cycle was documented for
Terrestrial invertebrates inhabiting lowland river floodplains of Central Amazonia and Central Europe: a review
TLDR
Some terrestrial invertebrates show physiological resistance against inundation or drought, phenologies fitting the normal annual rhythm of water level fluctuation, high dispersal ability and migration, and most species survive simply using a `risk strategy', combining high reproduction rates, dispersal and reimmigration following catastrophic events.

EFFECTS OF GLYCEROL ON COLD-HARDINESS IN INSECTS
TLDR
Evidence gathered from various diapausing species showed that glycerol accumulated during the fall, and an increase in concentration was observed in eggs of one species at temperatures ranging from −5° to 20 °C.
Pyruvic Acid, a Unique Component of an Exocellular Bacterial Polysaccharide
TLDR
Structural studies indicate the presence of one acid residue for each 51 hexose units in pyruvic acid, which has been isolated and identified as a component of a commercial red seaweed polysaccharide.

TLDR
Development in the Egg, moulting and metamorphosis, and some factors controlling fertility and fecundity and Sex determination.
The Influence of Anoxia on Lactate Utilization in Man after Prolonged Muscnlar Work
TLDR
A slight modification of Barker and Summerson's method of lactic acid determination is described, and the results indicate that under the specified conditions the rate of lactate utilization is not significantly altered by anoxia caused by inhalation of low percentage oxygen mixtures.
Amino Acids and Derivatives
Free amino acids and peptides are markedly hydrophilic compounds, only slightly soluble in non-aqueous solvents. This must be borne in mind when sampling and preparing materials for TLC as well as
Thin-layer chromatography.
