WebbCowles described the chronosequence of vegetation along sand dunes, moving from bare sand beach, to grasslands, to mature forests. A chronosequence is a “space-for-time” substitution, where ecologists can predict temporal patterns of vegetation based on a snapshot of an area gradient representing different ages of succession (Figure 1). WebbThis process of plant successionled to Cowles' second important theory: climax formation. A climax formationis the most stableplant community created by plant succession. All plant successionsare headed toward the establishment of a climax formation. margaret ellison obituary

Webb7 aug. 2024 · By comparing different types of succession (i.e. dunes and glaciers), we also found that legumes had higher N:P ratios in sand dune systems suggesting that legume growth might be more P-limited in these systems. Finally, grasses and forbs showed more constancy in their N:P ratios both across sand dune and glacier successions.
