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 ... -
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 ... -
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 ... -
Postfreeze reduction of locomotor endurance in the freeze-tolerant wood frog, Rana sylvatica.
Considerable study has focused on the physiological adaptations for freeze tolerance in the wood frog, Rana sylvatica, a northern species that overwinters within the frost zone, but little attention has been paid to the ... -
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 ... -
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, ... -
Physical Chemistry Interactive Plot: Kinetics: Parallel First Order Reaction, v1.0

Market Information on Sourcing Cellulosic Feedstock for Biofuel Production in Northern Plains Region of the United States
This study investigates the availability crop residues within 100 mile radius of a potential biorefinery in southeast North Dakota. Due to the lack of market information on biomass residue supply, we conducted farm focus ... -
The Logistics of Supplying Single vs. Multi-crop Cellulosic Feedstocks to a Biorefinery in Southeast North Dakota
This study investigates the economics of supplying cellulosic crop residue feedstocks within 100 mile (or 161 km) radius of a potential new biorefinery in southeast North Dakota. We utilize linear programming transportation ... -
Ice nuclei in soil compromise cold hardiness of hatchling painted turtles, Chrysemys picta.
Hatchling painted turtles (Chrysemys picta) commonly overwinter within their natal nests and survive exposure to temperatures as low as -12 degrees C by supercooling. We report that the supercooling capacity of hatchling ... -
Freezing impairment of male reproductive behaviors of the freeze-tolerant wood frog, Rana sylvatica.
The wood frog (Rana sylvatica), a temperate-zone anuran that overwinters within the frost zone, is adapted to tolerate the freezing and thawing of its tissues. Because the effects of freezing on complex neurobehavioral ... -
Inoculative freezing and the problem of winter survival for freshwater macroinvertebrates
Due to the thermal buffering of their environment, aquatic invertebrates are less likely than their terrestrial counterparts to face temperatures substantially below 0°C. Aquatic invertebrates may not be able to avoid ... -
Cold-hardiness of a laboratory colony of lone star ticks.
The cold-hardiness of a lone star tick, Ambylomma americium (L.) laboratory colony was characterized. Fed and unfed larvae, fed and unfed nymphs, and unfed adults did not survive exposure to -17C for 7 d. After an 8-d ... -
Anatomic site of application of ice-nucleating active bacteria affects supercooling in the Colorado potato beetle (Coleoptera: Chrysomelidae)
Most overwintering insects do not survive internal freezing and must avoid low temperatures or enhance the capacity of their body fluids to supercool to survive low temperature exposure. Recent reports have demonstrated ... -
Cold hardiness and overwintering strategies of hatchlings in an assemblage of northern turtles.
Field and laboratory studies were conducted during 1989-1994 to investigate the overwintering strategies of hatching turtles representing four families native to western Nebraska. Whereas hatchling snapping turtles (Chelydra ... -
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 ...
