Adaptations of frogs to survive freezing
Five species of frogs from North America survive extensive freezing of their body fluids to temperatures as low as -8C for periods lasting at least 2 weeks. These frogs hibernate in leaf litter where subzero temperatures ... -
Cryobiology of the freeze-tolerent gall fly Eurosta solidaginis: overwintering energetics and heat shock proteins
The goldenrod gall fly E urosta solidaginis (Diptera: Tephritidae) ranges from the southern us. northward into Canada. The larva overwinters within a ball gall on the stem of goldenrod Solidago spp. The galls often extend ... -
Cryobiology of the freeze-tolerant gall fly Eurosta solidaginis: Overwintering energetics and heat shock proteins.
The goldenrod gall fly Eurosta solidaginis (Diptera: Tehritidae) ranges from the southern U.S. northward into Canada. The larvae overwinters with a ball gall on the stem of goldenrod Solidago spa. The galls often extend ... -
Using microrespirometers to measure oxygen consumption by insects and small invertebrates.
A variety of physiological studies require the measurement of oxygen consumption. Unfortunately, the techniques for measuring respiration rate often require expensive equipment or difficult procedures that are not available ... -
Ice nucleating active bacteria reduce the cold-hardiness of the freeze-intolerant Colorado potato beetle (Coleoptera: Chrysomelidae).
In laboratory experiments, a freeze-dried concentrated form of the icenucleating active bacteria, Pseudomonas syringae, was used to decrease the supercooling capacity of field-collected diapausing Colorado potato beetles, ... -
Ice-nucleating active bacteria decrease the cold-hardiness of stored grain insects.
This report provides further evidence that a freeze-dried, concentrated form of Pseudomonas syringae, an ice-nucleating active bacteria, reduces the cold tolerance of stored grain insect pests. Application of ice-nucleating ... -
Topical application of ice-nucleating-active bacteria decreases insect cold tolerance
The majority of overwintering insects avoid lethal freezing by lowering the temperature at which ice spontaneously nucleates within their body fluids. We examined the effect of ice-nucleating-active bacteria on the ... -
Surviving the big chill: overwintering strategies of aquatic and terrestrial insects.
The purpose of this paper is to describe the cold-hardiness of aquatic insects and to use the literature to compare physiological and behavioral strategies that aquatic and terrestrial insects use to cope with minimum ... -
Cold-hardiness in the Antarctic tick, Ixodes uriae.
Ixodes uriae White (Ixodidae, Acarina) is the predominant tick on the Antarctic peninsula.This species has a circumpolar distribution in both hemispheres and is associated with or known to parasitize 48 species of seabirds. ... -
Cold-shock injury and rapid cold-hardening in the flesh fly, Sarcophaga crassipalpis.
Direct exposure to -10 C, in the absence of tissue freezing, causes high mortality in Sarcophaga crassipalpis: this result suggests that injury is due to cold shock. However, brief acclimation at 0 C enables larvae, ... -
Low temperature acclimation in the desert spider, Agelenopsis aperta.
Agelenopsis aperta (Gertsch) inhabits desert grasslands and lava beds in the southwestern U.S.A. The capacity of this species to cold-harden was assessed by exposing second generation laboratory- reared specimens to an ... -
Do bot flies, Cuterebra (Diptera: Cuterebridae), emasculate their hosts?
Asa Fitch, in his description of a new species of Cuterebra that he named, "emasculator," was the first to suggest that bot flies castrated their mammalian hosts. In recent years several major review papers and parasitology ...
