Abstract
The ability of plants to maintain water flow
through leaves under water stress-induced tension (assessed
as the leaf hydraulic vulnerability; P50leaf) is intimately
linked with survival. We examined the significance of
P50leaf as an adaptive trait in influencing the dry-end distributional
limits of cool temperate woody angiosperm
species. We also examined differences in within-site variability
in P50leaf between two high-rainfall montane rainforest
sites in Tasmania and Peru, respectively. A
significant relationship between P50leaf and the 5th percentile
of mean annual rainfall across each species distribution
was found in Tasmania, suggesting that P50leaf
influences species climatic limits. Furthermore, a strong
correlation between P50leaf and the minimum rainfall
availability was found using five phylogenetically independent
species pairs in wet and dry evergreen tree species,
suggesting that rainfall is an important selective agent in
the evolution of leaf hydraulic vulnerability. Greater
within-site variability in P50leaf was found among dominant
montane rainforest species in Tasmania than in Peru
and this result is discussed within the context of differences
in spatial and temporal environmental heterogeneity and
parochial historical ecology.
