Physical Chemistry Interactive Plot: Kinetics: Parallel First Order Reaction, v1.1
html file encoding for an interactive plot for parallel first order reactions. -
Cryoprotectants and extreme freeze tolerance in a subarctic population of the wood frog.
Wood frogs (Rana sylvatica) exhibit marked geographic variation in freeze tolerance, with subarctic populations tolerating experimental freezing to temperatures at least 10-13 degrees Celsius below the lethal limits for ... -
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 ... -
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 ... -
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 ... -
Enzymatic regulation of glycogenolysis in a subarctic population of the wood frog: implications for extreme freeze tolerance
The wood frog, Rana sylvatica, from Interior Alaska survives freezing at –16°C, a temperature 10–13°C below that tolerated by its southern conspecifics. We investigated the hepatic freezing response in this northern phenotype ... -
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 ... -
Brief chilling to subzero temperature increases cold hardiness in the hatchling painted turtle (Chrysemys picta)
Although many studies of ectothermic vertebrates have documented compensatory changes in cold hardiness associated with changes of season, much less attention has been paid to adjustment of physiological functions and ... -
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 ... -
Full-Cycle Assessment of Critical Thinking in an Ethics and Science Course
Enhancing critical thinking skills for undergraduate students is important across the curriculum and between disciplines. We report on a method of improving critical thinking skills, which was studied through an Ethics and ... -
Using Matched Samples to Look for Sex Differences
The reasons for observed differences in physics performance between men and women have yet to be clearly determined. This study asks the question: if men and women have a similar background at the start of an introductory ... -
Student Perceptions of an Introductory Laboratory Course
We surveyed students taking an introductory university physics laboratory course over the summer. These students are science majors, but not physics majors. Eighteen students were interviewed, asked what they thought the ... -
Creating, implementing, and sustaining an advanced optical spectroscopy laboratory course
An upper-division laboratory course in atomic and molecular spectroscopy is described. Examples of outcomes that also benefit second-year physics laboratories and demonstrations in introductory courses are presented. The ... -
Self-Efficacy in Introductory Physics in Students at Single-Sex and Coeducational Colleges
We surveyed 88 students at four colleges: one men’s college, two women’s colleges, and one coeducational college. The questions, modified from Reid (2007), asked about in-class participation, how fulfilled they were by ... -
What Do Students Want? Small Group Instructional Diagnoses of STEM Faculty
Small Group Instructional Diagnoses (SGIDs) are informal, mid-semester evaluations of courses, which the instructors request voluntarily. The facilitator of the SGID comes into a class, the instructor leaves, and the ... -
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 ...
