The amount injected corresponds to the difference between the mean and maximum values of androgens per yolk, ensuring that the final yolk androgen level in the androgen-treated clutches was on average at the upper limit of the natural range.
The researchers found: "For heat-related extremes, the additional 0.5C marks the difference between events at the upper limit of present-day natural variability and a new climate regime, particularly in tropical regions".
Schleussner concluded that going from 1.5 to 2C "marks the difference between events at the upper limit of present-day natural variability and a new climate regime, particularly in tropical regions".
Thus, the maximum sulfide concentrations measured in the WDP1 treatment wetland (which are similar to the upper limit of H2S in natural sulfidic waters) are at the lower end of the range of total sulfide employed in the experimental studies.
Some countries, including Canada, agreed to an "aspirational goal" of a 1.5 degrees Celsius limit at the 2015 Paris Climate Conference; the difference between 1.5 and 2 degrees of warming "marks the difference between events at the upper limit of present-day natural variability and a new climate regime," according to a recent study written by climate researchers.
The human ear can hear single frequencies of vibration from around 20 to 20,000 hertz (Hz), although reductions occur during the natural aging process, particularly in the upper limit of the range.
A bathymetrical succession of natural patches was outlined from the lower to the upper limit of the meadow, with a long-term dynamic opposed to a shorter one concerning anthropogenic patches.
The natural logarithmically transformed bias (and lower to upper limit of agreement) in optimal VB predicted by PTM and PB was −0.001 (−0.012 to 0.010).
The ε value calculated here is lower than the upper limit of sulfur isotope fractionations found to be between 0 and 72‰ in the natural environment (Wortmann et al., 2001; Brunner & Bernasconi, 2005; Canfield, 2001; Sim et al., 2011).
