It is now widely known that Antarctic air is warming faster than the rest of the world, and theAntarcticPeninsula has experiencedmajorwarming over the last 50years.Themonthly mean near surface temperature at the Faraday/Vernadsky station has increased considerably, at a rate of 0.568C per decade over the year and at 1.098C per decade over thewinter. The increase is not the same over all the sta...

The steady state extension and rotation rates of the Phycomyces sporangiophore were measured as a function of temperature. Maximum growth occurred at 27 degrees C; maximum rotation at 28 degrees C. The rotation to extension ratio, a qualitative parameter of cell wall structure, is affected differently by high and low temperatures. Steady state counterclockwise rotation, as opposed to the normal...

Hotter is better is a hypothesis of thermal adaptation that posits that the rate-depressing effects of low temperature on biochemical reactions cannot be overcome by physiological plasticity or genetic adaptation. If so, then genotypes or populations adapted to warmer temperatures will have higher maximum growth rates than those adapted to low temperatures. Here we test hotter is better by meas...

In this study we examine the Urban Heat Island (UHI) of Granada. First, we perform a study of the evolution of the recorded temperatures at a meteorological station over the last century. In this record, the minimum temperatures increase while the maximum temperatures decrease. We also compare both rural and urban temperature records, obtaining the UHI fluctuations on a smaller time scale. The ...

This paper develops trend estimation techniques for monthly maximum and minimum temperature time series observed in the 48 conterminous United States over the last century. While most scientists concur that this region has warmed on aggregate, there is no a priori reason to believe that temporal trends in extremes and averages will exhibit the same patterns. Indeed, underminor regularity condit...

We quantify the locomotor capacity of the round-tailed ground squirrel (Spermophilus tereticaudus), a mammal that can lower energetic costs by relaxing thermoregulatory limits without becoming inactive. We measured maximum sprint speed, maximum limb cycling frequency and maximum force production in animals at body temperatures ranging from 31 degrees C to 41 degrees C. We found no thermal depen...

Relationships between stream water and air temperatures are often modeled using linear or nonlinear regression methods. Despite a strong relationship between water and air temperatures and a variety of models that are effective for data summarized on a weekly basis, such models did not yield consistently good predictions for summaries such as daily maximum temperature. A good predictive model f...
