Primary succession in Mount Pinatubo
Vegetation structure on the east flank of Mount Pinatubo was investigated to determine the inventory of species at 15 y post-eruption, then to ascertain environmental variables that have influenced the early patterns of primary succession. Unconstrained and constrained ordination methods were used to determine the influence of spatial, elevation, and substrate patterns on vegetation. Vegetation...
متن کاملPrimary succession on Mount St. Helens, with reference to Surtsey
STUDY AREA The 18 May 1980 eruptions of Mount St. Helens formed a complex pattern of new and denuded land (Dale et al. 2005). This extraordinary landscape beckoned irresistibly to ecologists to study reassembly (Fig. 1). This report draws on studies conducted by myself and colleagues since 1980. Methods are in the references. Vegetation structure was monitored in transects of permanent plots: 1...
متن کاملEarly primary succession on the volcano Mount St. Helens
focus on primary succession in habitats formed on May 18, 1980, to explore mechanisms that control establishment of plants on new landforms. The rate of early primary succession is generally believed to be slow (cf. Crocker & Major 1955; Shure & Ragsdale 1977; Houle & Phillips 1989), though rates can differ significantly. As conditions are ameliorated by weathering and nutrient accumulation, th...
متن کاملClimate forcing by the volcanic eruption of Mount Pinatubo
[1] We determine the volcano climate sensitivity l and response time t for the Mount Pinatubo eruption, using observational measurements of the temperature anomalies of the lower troposphere, measurements of the long wave outgoing radiation, and the aerosol optical density. Using standard linear response theory we find l = 0.15 ± 0.06 K/(W/m), which implies a negative feedback of 1.4 (+0.7, 1.6...
متن کاملMechanisms of Early Primary Succession in Subalpine Habitats on Mount St. Helens'
In the 6 yr following the 1980 eruption of Mount St. Helens in Washington state, vascular plant invasion of barren substrates in subalpine habitats has been limited despite the proximity of seed sources from resprouted vegetation. From 1983 to 1985 we counted 1st-yr seedlings and estimated percent cover of adults in grids of permanent plots located across the ecotone between residual vegetation...
