However, on long term timescales such as millennium scale, chemical weathering may be more important to regulate the long term trend of Rb/Sr ratios in lake sediment.
Negative correlation between DSGSD abundance and mean annual rainfall suggests that effective hydrological surface processes contribute, on the long-term timescale, to the development of large-scale topography unfavourable to DSGSDs, especially in areas of high exhumation rates.
In situ cosmogenic nuclide concentrations such as 10Be and 26Al are directly related to denudation rate, allowing quantification on long-term timescales (Gosse and Phillips 2001).
Energy policy is beset by deep uncertainties, owing to the scale of future transitions, the long-term timescales for action, and numerous stakeholders.
Therefore, as shown by Chen et al. [3, 4], higher Rb/Sr ratios in a loess/paleosol profile correlated to higher degree of weathering, and thus to stronger monsoon precipitation on long-term timescales.
Our results support the view that mutators may not able to persist on long-term timescales in nature (de Visser 2002).
This intermittency of erosion requires instantaneous erosion rates to be greater than long term averages, explaining how timescale averaging can impact estimates of glacial erosion rates.
We note that, because of timescale separation, the long term evolutionary dynamics of adaptive immunity can be studied by modeling adaptive immunity as a sort of stronger "innate immunity" with a higher cost.
But it's a question of timescale, he says: "In the long term there are very few available options: renewables, fission and fusion".
In this study, we examined how metabolic systems are altered in diabetes and how these changes are related to glycaemic control over three different timescales (acute, short term and long term) across three biofluids (plasma, urine and saliva).
