INFORMATION. 1. Identifying ecological strategies based on functional
traits has been one of the main focuses of studies on plant community
assembly. Recently, an important and timely tool, “StrateFy”, has been
proposed for detecting plant strategies across the globe according to the
CSR scheme. The CSR scheme is undeniably efficient across scales, and
distinct CSR strategies among species have been proposed to explain
differing degrees of dominance among species. However, in a previous study
we showed that dominance ranking of woody species in a resource-poor
habitat (coastal sandy plain) was not explained by morphological traits
commonly measured in functional approaches (such as those used to estimate
CSR strategies), but by integrative traits (i.e. traits that are the
result of different combinations of functional traits) more related to
plant performance. 2. Here, we used CSR analysis and StrateFy on a dataset
collected on a coastal sandy plain to test the hypothesis that the
dominance ranking would be compatible with the CSR strategies; i.e., that
dominant species would show a greater proportion of the stress-tolerance
(S%) strategy than subordinate species. 3. Contrary to our hypothesis, all
species exhibited an S/CS strategy, and the most-dominant species had
neither similar values nor the highest S%. The inability of CSR analysis
(as applied using StrateFy) to predict dominance ranking suggests that it
can explain relative dominance when different strategies co-occur, but not
in cases where dominant and subordinate plants share the same strategy. 4.
We argue that the relative importance of CSR and integrative traits for
describing dominance ranking may depend on how CSR strategies are filtered
in each environment. In environments where only a narrow range of strategy
classes are viable, integrative traits may be more important for
explaining variation in degrees of dominance. Thus, the ability of a given
species to achieve dominance may depend on integrative traits resulting
from multiple trait arrays, not necessarily captured by the SLA, LDMC and
LA measurements that are used to calculate the relative proportions of
strategies in StrateFy.
