Compact genome of the Antarctic midge is likely an adaptation to an extreme environment
The midge, Belgica antarctica, is the only insect endemic to Antarctica, and thus it offers a powerful model for probing responses to extreme temperatures, freeze tolerance, dehydration, osmotic stress, ultraviolet radiation ...
Identification and expression of a putative facilitative urea transporter in three species of true frogs (Ranidae): implications for terrestrial adaptation.
Urea transporters (UTs) help mediate the transmembrane movement of urea and therefore are likely important in amphibian osmoregulation. Although UTs contribute to urea reabsorption in anuran excretory organs, little is ...
Seasonal variation in the hepatoproteome of the dehydration- and freeze-tolerant wood frog, Rana sylvatica
Winter’s advent invokes physiological adjustments that permit temperate ectotherms to cope with stresses such as food shortage, water deprivation, hypoxia, and hypothermia. We used liquid chromatography (LC) in combination ...
Seasonality of Freeze Tolerance in a Subarctic Population of the Wood Frog, Rana sylvatica
We compared physiological characteristics and responses to experimental freezing and thawing in winter and spring samples of the wood frog, Rana sylvatica, indigenous to Interior Alaska, USA. Whereas winter frogs can survive ...
Carrion - It's what's for dinner: Wolves reduce the impact of climate change.
Humans have viewed wolves as competitors, threats to personal safety, and symbols of evil throughout history. By the early part of the 20th century, grey wolves (Canis lupus) had been eradicated from 42% of their historic ...
Physiological Ecology of Overwintering in the Hatchling Painted Turtle: Multiple-Scale Variation in response to Environmental Stress
We integrates field and laboratory studies in an investigation of water balance, energy use, and mechanisms of cold-hardiness in hatchling painted turtles (Chrysemys picta) indigenous to west-central Nebraska (Chrysemys ...
Identification of ice nucleating active Pseudomonas fluorescens strains for biological control of overwintering Colorado potato beetles (Coleoptera: Chrysomelidae).
Laboratory studies were conducted to identify ice-nucleating active bacterial strains able to elevate the supercooling point, the temperature at which freezing is initiated in body fluids, of Colorado potato beetles, ...
Survival and physiological responses of hatchling Blanding's turtles (Emydoidea blandingii) to submergence in normoxic and hypoxic water under simulated winter conditions.
Abstract Overwintering habits of hatchling Blanding’s turtles (Emydoidea blandingii) are unknown. To determine whether these turtles are able to survive winter in aquatic habitats, we submerged hatchlings in normoxic (155 ...
Cold-hardiness and evaporative water loss in hatchling turtles.
North American turtles hatch in late summer and spend their first winter either on land or underwater. Adaptations for terrestrial overwintering of hatchlings in northern regions, where winter thermal and hydric regimes ...
Winter biology & freeze tolerance in the goldenrod gall fly
Birds migrate. Bears hibernate. Turtles and
frogs retreat to the bottom of lakes. Most animals must
avoid harsh winter conditions; few can survive freezing.
Larvae of the goldenrod gall fly (Eurosta solidaginis),
can ...
