Mixing with modern groundwater may slightly elevate the noble gas temperatures (NGTs) of glacial-age samples while making them appear substantially younger. Given the uncertainty in dating, we cannot rule out a larger LGM temperature depression of up to similar to 6 degrees C. The similar to ...
(Fig. 2.4B). Annual ryegrasses are not true annuals, but they were developed in the southern United States by breeding varieties that would establish quickly in autumn, produce high yields ofquality forageduring winter, and die out in summer when the temperatures become high. A few varieties...
Rising global temperatures are increasing exposure to heat stress, which harms human health. Heat stress is caused by the body’s inability to cool down properly through sweating. Body temperature can rise rapidly, and high temperatures may damage the brain and other vital organs. What’s more,...
Hourly global radiation sums are given in Chapter 3.2, the method for determining daily distribution of ambient air temperature (averaged for every month of a year) are described in Section 6.2.3 (Eqns (6.37)–(6.40)). Average monthly ambient air temperatures are presented in Table 6.7 (...
In the 1998 warm, El Nio winter, no bay-wide winter–spring phytoplankton flowered. Bloom limitation was correlated with warm temperatures which may have stimulated grazing rates. The lack of a bloom did not change annual levels of primary production but this alteration in carbon flow may impact...
Mortality of Epiphyas postvittana (Lepidoptera: Tortricidae) after exposure to sodium bicarbonate at elevated temperatures or combined with emulsifiers Mortality responses of fifth instar Epiphyas postvittana Walker (lightbrown apple moth) larvae on apples to immersion in solutions of: (1) 0.55% sodium...
(model 1b, Table1). BothTmeanand hydroperiod had a negative slope, with lower elevation gains associated with longer hydroperiods and higher air temperatures. Overall, the AIC/BIC diagnostics and tabulated statistics for both models indicate that model 1b for ΔEprovided a better fit to the ...
Finally, the positive and significant interaction between the high-frequency component of summer-NAO of the year before masting and the low-frequency component of winter-NAO we found in the beech model could be interpreted as a higher sensitivity of the species to high temperatures inducing floweri...
temperatures are substantially colder and the jet is more intense during Southern Hemisphere winter. The autumn and winter westerly jets extend throughout the mesosphere, exhibiting an equatorward tilt with height. The seasonal sequence shows that the polar night jet forms initially in the upper ...
by water produced by metabolism. However, water needs for lactation and for activity are provided by consuming insects and herbaceous plant materials. Most small mammals are nocturnal or crepuscular and live in burrows or burrow systems that are lower than midday soil surface temperatures in summer....
