Areas that have not seen fire for many years--much longer than the historic fire interval rate--will be more prone to very intense, hot fires.
However, in this old growth forest ecosystem the historic fire return interval is estimated to be 230 years compared to our study area that burned every three to five years (Agee [1993]).
The model predicted historic mean fire return intervals from TRI and two human population variables.
From the 1930s, historical geography gained prominence through the valuable studies in sequent occupance i.e., the study of the human occupation of a specific region over intervals of historic time initiated by Derwent S. Whittlesey and Carl O. Sauer.
The last ~100 years of our record is especially well resolved (e.g. sub-decadal for the top 5 cm of relict pore ice) due to the finer pore ice sampling resolution through this interval, and the historic cryptotephra (1912 CE Novarupta-Katmai at 10 cm depth) and post-bomb 14C dating (−35 cal yr BP at 4 5 cm depth) that constrain this part of the chronology (Tables S1, S2).
Although a few studies have examined paleo-tsunami deposits along the Sanriku coast, additional studies of paleo-earthquakes and tsunamis are needed to improve our knowledge of the timing, recurrence interval, and size of historical and pre-historic tsunamis.
c The daily probability of first flowering of four species cherry blossoms and their 95% intervals (lines) for the historic (1981 2000) and future (2081 2100) periods [48].
Two fire regimes were also parameterized: current fire regime with a fire return interval of 300 years and a historic fire regime with an overall average fire return interval of 50 years.
A comparison of the proposed method with historic average method (predicted flow in the given time interval is the average of the preceding 3 days flow in the same time interval) and naive method (flow today equals flow yesterday in the same time interval) was attempted and the results are shown in Fig. 4.
Our historic needs for large kindreds to refine the relevant genetic interval and cumbersome analyses for positional cloning have limited the diseases amenable to study.
"The historic concept of departmental questions held at fixed, often lengthy intervals will be antiquated.
