While several studies have examined the abiotic effects of altitude (low ambient temperatures and hypoxia) on the aerobic performance of small mammals, few have explored the effects of development and maturation at different altitudes on aerobic performance as adults. We examined the basal metabolism and aerobic performance of deer mice (Peromyscus maniculatus) under four different developmenta...

Cold acclimation is an important adaptive response of plants from temperate regions to increase their freezing tolerance after being exposed to low nonfreezing temperatures. The three CBF genes are well known to be involved in cold acclimation. As the 3 CBF genes are linked tandemly in the Arabidopsis genome, it is almost impossible to obtain cbf triple mutants using traditional genetic methods...

Use of global positioning system (GPS) transmitters provides opportunities to evaluate ecological questions associated with fine-scale animal movements. One important application is to evaluate how animals acclimate to new surroundings after translocation. Our objective was to quantify temporal acclimation for low-elevation, non-migratory bighorn sheep (Ovis canadensis) from 3 translocations to...

Without question, the educational research community has garnered much from past decades of expert/novice theory and research. Framed largely by artificial intelligence and information-processing theory, those traditional research programs initially took shape in the 1970s and 1980s around the problem-solving performance of experts. The primary goal was to determine the characteristics and acti...

This study investigated the between trial variation of thermoregulatory measures during a heat acclimation protocol. Eight 14-16 y old boys completed three bouts of 20-min cycling at 45 % peak VO2 in a hot environment (35.1 ± 1.2 °C and 46. 4 ± 1.0 % relative humidity) on two occasions separated by a minimum of 24 h. Reliability was assessed through analysis of within-subject variation, the cha...

Temperate plants develop a greater ability to withstand freezing in response to a period of low but nonfreezing temperatures through a complex, adaptive process of cold acclimation. Very little is known about the signaling processes by which plants perceive the low temperature stimulus and transduce it into the nucleus to activate genes needed for increased freezing tolerance. To help understan...
