| 1 | Demographic trends and climate over 35 years in the Barro Colorado 50 ha plot显示文摘Background:The first three censuses of the 50-ha plot at Barro Colorado Island spanned an unusually harsh dry season during the 1983 El Nino.By the early 1990 s,we had documented increases in tree mortality,tree growth,and large population fluctuations of many species during the 1982-1985 census interval.At the time,we asserted that increasing drought frequency would greatly affect the forest.With the benefit of five more censuses at Barro Colorado from 1995-2015,we can now put the 1980 conditions in a longer perspective and test the hypothesis that increasing droughtiness has continued to change the forest.Methods:A 50-ha forest plot on Barro Colorado Island was censused eight times,in 1982 and every five years since1985.All free-standing woody stems were measured,mapped,and identified In each census.Results:1) The period 1982-1992 included several extreme dry seasons,not just 1983,but since then there have been few such droughts.2) Dbh growth declined from a peak in the early 1980 s to its lowest in the early 1990 s.From 1995-2015 it increased slightly,but not returning to the initial peak.Nearly every species and all dbh categories followed the same pattern.3) The elevated stand-wide mortality rate of large trees during the 1982-1985 drought has not returned,and most individual species showed the same pattern of elevated mortality in the 1980 s followed by low and fairly stable mortality after 1990.4) Sapling mortality declined after 1985,but rose again in the late-90 s,so the 1980 s drought period no longer looks unusual.Mortality of individual species' saplings fluctuated erratically,including cases where mortality during the drought was lower than after.5) Population sizes of individual species fluctuated in all possible directions.Some species declined precipitously during the drought,then recovered,but others did not recover.Other species increased in abundance during the drought.Conclusions:Droughts of the 1980 s elevated tree growth and mortality at Barro Colorado,but since 1990,demographic rates have remained lower,paralleling a moderate climate with few severe droughts after 1990.Moisture-demanding species suffered during the drought,but many have since recovered.We do not know how often such drought periods recur.Moreover,many species' abundances fluctuated over 35 years with no known cause. | Richard Condit Rolando Pérez Suzanne Lao Salomón Aguilar Stephen P.
