We determined the chronological timeframe of paleogeographical events.
Several cases of faunal exchanges in both directions between North Africa and Arabia have been described (e.g. [ 2, 13, 24]) showing that there is not a single pattern, but rather different hypotheses including both vicariance and dispersal, heavily dependent on the estimated timeframe of the events.
The timeframe of this event coincides with the recent uplift of the QTP, which occurred between 1.6 and 3.4 Ma [ 21, 22, 56].
Genome information from additional amphibians would allow us to narrow the timeframe of this event but at this stage we can only conclude that it occurred sometime after the divergence of Amphibia and Amniota.
Plan what video games you're going to play, the timeframe of the event, and what charity you'll be playing for.
Our study provides further evidence that short-term rates can be much higher and that a failure to take this into account will lead to overestimation of the timeframe of recent evolutionary events.
Effectively, in an event study, a model is applied to estimate the difference between the normally Expected Return (ER) and the Return (R) of a stock within a timeframe of a specific event.
The timeframe of the case study was pre-implementation, but this is also the timeframe least studied.
Lamington was the major relative contributor to the hazard at this site at the 100-year timeframe with events at all magnitudes represented totalling 33%% of the ash load anticipated for this site.
Taal was responsible for the majority of the hazard at the 100-year timeframe with events at all magnitudes represented (mostly VEI 3 and VEI 4) totalling ~27%% of the ash load anticipated for this site.
Over the two-year timeframe, Yates repeated his misleading version of events to two Commons select committees and visited the Guardian to complain to the editor, Alan Rusbridger, about the paper's coverage.
