Rates of tree mortality at the La Selva Biological Station, Costa Rica. m is the exponential annual rate of mortality [48]. N 2016 is number of large trees alive at the 2016 census for cohorts with different first census dates. The weighted average annual mortality is the sum of each first census sample size multiplied by the associated mortality rate, divided by the sum of sample sizes [49].
