“…Across 41 rainforest trees, LLS was positively correlated to mass-based condensed tannin contents (Coley 1988). Across seven winter-deciduous trees in Japan, LLS was positively correlated to mass-based total phenolic contents, but it was not correlated to mass-based condensed tannin contents (Matsuki and Koike 2006). In the present study, LMA was positively correlated to N-based condensed tannins, but LLS was not correlated to either N-based condensed tannins or total phenolics (Table 3) nor to massbased condensed tannins or total phenolics (data not shown).…”

We examined 15 traits in leaves and stems related to leaf C economy and water use for 32 co-existing angiosperms at ridge sites with shallow soil in the Bonin Islands. Across species, stem density was positively correlated to leaf mass per area (LMA), leaf lifespan (LLS), and total phenolics and condensed tannins per unit leaf N (N-based), and negatively correlated to leaf osmotic potential and saturated water content in leaves. LMA and LLS were negatively correlated to photosynthetic parameters, such as area-, mass-, and N-based assimilation rates. Although stem density and leaf osmotic potential were not associated with photosynthetic parameters, they were associated with some parameters of the leaf C economy, such as LMA and LLS. In the principal component (PCA) analysis, the first three axes accounted for 74.4% of total variation. Axis 1, which explained 41.8% of the total variation, was well associated with parameters for leaf C and N economy. Similarly, axis 2, which explained 22.3% of the total variation, was associated with parameters for water use. Axis 3, which explained 10.3% of the total variation, was associated with chemical defense within leaves. Axes 1 and 2 separated functional types relatively well, i.e., creeping trees, ruderal trees, other woody plants, C(3) shrubs and forbs, palms, and CAM plants, indicating that plant functional types were characterized by similar attributes of traits related to leaf C and N economy and water use. In addition, when the plot was extended by two unrelated traits, leaf mass-based assimilation rates and stem density, it also separated these functional types. These data indicate that differences in the functional types with contrasting plant strategies can be attributed to functional integration among leaf C economy, hydraulics, and leaf longevity, and that both leaf mass-based assimilation rates and stem density are key factors reflecting the different functions of plant species.

“…These differences in C/N may be more influenced by abiotic factors that shape plant ecophysiology ) than by a response to herbivory. Matsuki and Koike (2006) showed that across seven species of deciduous broad-leaved trees that differed in their leaf life span, C/N correlated negatively with total N and herbivore survival, revealing that older leaves with low nitrogen content were less suitable for caterpillar growth. Following monarch feeding on A. barjoniifolia and A. fascicularis, C/N increased; this could be a result of metabolite reallocation and changes in Fig.…”

Induced Responses to Herbivory and Jasmonate in Three Milkweed Species

2009

We studied constitutive and induced defensive traits (latex exudation, cardenolides, proteases, and C/N ratio) and resistance to monarch caterpillars (Danaus plexippus) in three closely related milkweed species (Asclepias angustifolia, A. barjoniifolia and A. fascicularis). All traits showed significant induction in at least one of the species. Jasmonate application only partially mimicked the effect of monarch feeding. We found some correspondence between latex and cardenolide content and reduced larval growth. Larvae fed cut leaves of A. angustifolia grew better than larvae fed intact plants. Addition of the cardenolide digitoxin to cut leaves reduced larval growth but ouabain (at the same concentration) had no effect. We, thus, confirm that latex and cardenolides are major defenses in milkweeds, effective against a specialist herbivore. Other traits such as proteases and C/N ratio additionally may be integrated in the defense scheme of those plants. Induction seems to play an important role in plants that have an intermediate level of defense, and we advocate incorporating induction as an additional axis of the plant defense syndrome hypothesis.

“…These two coexisting species exhibited distinct leaf life spans, with P. koraiensis being 36-48 months and Q. mongolica being ca. 6 months (Matsuki and Koike, 2006). In this study, we expect to: (1) determine the appropriate light environment facilitating the highest survival and growth rates for the seedlings of both tree species; (2) compare the survival and growth of the two coexisting species under the same light level; (3) explain how NSC storage varied with natural light levels, and find their correlations with final survival for those two coexisting species.…”

Comparison of Leaf Life Span, Photosynthesis and Defensive Traits Across Seven Species of Deciduous Broad-leaf Tree Seedlings

Abstract: These results indicate that species with a shorter leaf life span have higher photosynthetic productivity and are more susceptible to herbivore attack than species with a longer leaf life span. This supports the "cost-benefit hypothesis".
