The SPI was calculated for a time scale of six months (ending in May) in a year corresponding to the growth period of common crops (wheat) in the study area (Vergni and Todisco 2011).
In the case of the Fabaceae family, three species have been sequence (Medicago truncatula, Lotus japonicus and Glycine max), but their divergence times would represent a time scale of 50 60 million years [ 29].
Da29 could be considered as the basal haplotype of the Balkan clade, with the genetic distance between Da29 and other haplotypes ranging between 0.75 and 1.65%, which is equivalent to the time scale of 750 000-1.65 million years when grayling of northern, Slovenian and southern, Serbian clusters differentiated.
Similarly, Durrett and Schmidt (2008) specifically examined the case of pairs of sites and estimated that in Drosophila a pair of mutations can inactivate a binding site and activate another on the time scale of several million years, consistent with empirical observations (Ludwig et al. 1998; Swanson et al. 2011).
For disaster preparedness in Japan, it is important to examine the occurrences of Level 2 tsunamis over time scales of several thousand years based on analyses of tsunami deposits.
These previous studies, which were conducted before the 2011 Tohoku-oki earthquake, demonstrate that tsunami deposits can reveal information about the occurrence and extent of mega-tsunamis over time scales of several thousand years.
Over a time scale of one hundred to several hundred years, forest disturbances including treatment or wildfire will only result in forest C loss if the forests are not allowed to recover in the time period between disturbances [16],[16].
Over a time scale of one hundred to several hundred years, forest disturbances including treatment or wildfire will only result in forest C loss if the forests are not allowed to recover in the time period between disturbances [ 16],[ 23].
"I would expect that on the time scale of a year or two this should be settled".
Depending on the language, this implies a time scale of a few years to at best one or two decades.
