“…The carbon isotope ratios found in our material are somewhat different from those presented by Ting et al (1985) and Sternberg et al (1987) for C. rosea. In the plants they studied in southern Florida, CAM was more pronounced in the dry season compared to the rainy season and in the juvenile epiphtytic stage compared to rooted trees.…”

“…In contrast, the values of the present investigation, where only rooted trees were studied, range up to -14.7%0 for C. rosea and up to -14.1%0 for C. alata, showing that in adult and rooted trees (see Fig. 2a-c) CAM is just as strongly expressed as in the epiphytic specimens analysed by Sternberg et al (1987). The latter authors also suggested that there might be differences between leaves of different age.…”

“…The occurrence of crassulacean acid metabolism (CAM) in Clusia was first reported by Tinoco and Vazquez-Yanes (1983) and then further described by Ting et al (1985) and Sternberg et al (1987). In the genus Clusia there are approximately 145 species occurring in the warm Americas, Madagascar and New Caledonia (Willis 1973).…”

“…The species studied by Tinoco and VazquezYanes (1983) in Mexico and by Ting et al (1985) and Sternberg et al (1987) at Saint John Island (Virgin Islands, USA) and in an arboretum in Florida were C. lundelli Standley and C. rosea Jacq., respectively. We now present evidence of the occurrence of CAM in an additonal species of Clusia and also in habitats of varying degrees of aridity, in the state of Falcon in northern Venezuela, where material of C. alata Planch and Triana, C. rosea Jacq.…”

summary Clusia rosea Jacq. is abundant in the moist parts of the Caribbean island of St John (US Virgin Islands, Lesser Antilles) but relatively rare along the dry south coast. Three types of seedlings were encountered, terrestrial seedlings, seedlings growing as humus‐epiphytes on other trees, and seedlings growing inside the tanks of the bromeliad Aechmea lingulata (L.) Baker. Free‐living trees grow from terrestrial seedlings or from epiphytic seedlings strangling and shading their host trees. Leaf‐Na+ levels were always low (1–4 mequiv I−1 tissue water); trees close to the shore were not affected by salinity. In leaves of mature C. rosea trees, levels of Ca2+, Mg2+ and K+ were about 60–90, 40–50, 45–55 mequiv I−1 tissue water, respectively. Epiphytic seedlings tended to contain lower levels of these inorganic cations than seedlings growing terrestrially or in the tanks of Ae. lingulata. Epiphytic seedlings contained significantly less nitrogen than terrestrial seedlings. In the leaves of mature trees N‐levels were independent of altitude and location on the island, but shaded leaves had significantly higher N‐levels than exposed leaves. Light compensation point of photosynthesis in epiphytic seedlings performing C3‐photosynthesis was 17–5 (μmol photons m−2 s−1), photosynthesis was saturated at about 300μmol photons m−2 s−1 showing a maximum rate of CO2‐uptake of 2–3 μmol m−2 s−1.

Plasticity of source‐water acquisition in epiphytic, transitional and terrestrial growth phases of Ficus tinctoria

Despite continued studies on the ecology and physiology of strangling hemiepiphytes, there is little quantitative information about the variations in source‐water uptake by these species under different growth phases. In this study, the water acquisition patterns of a hemiepiphyte, Ficus tinctoria, is investigated in relation to growth phase (epiphytic, transitional and terrestrial) and season (foggy, hot‐dry and rainy). Stable isotope compositions of water in xylem, soil, canopy humus, fog and rainfall were sampled on seasonally distinct dates, and soil water content and leaf carbon isotope composition were measured in order to determine the proportion of different water sources. Results indicated that F. tinctoria displayed a high degree of plasticity in source‐water acquisition associated with the growth‐phase transition from purely canopy‐rooted epiphyte to transitional plant to terrestrial tree. During the foggy season and the hot‐dry season, epiphytes utilized a combination of recently received rainwater (82–89%) and fog water (11–18%) present in canopy humus soil, whereas terrestrial trees exclusively depended on shallow and deep terrestrial soil water and exhibited marked flexibility in depth of soil water uptake. Transitional‐phase plants relied predominantly on shallow soil water (79–86%) and extracted only a small fraction of canopy humus water (14–21%). During the rainy season, epiphytes relied almost exclusively on recent rainwater (96%) and had a negligible water uptake from fog, whereas trees extracted their water primarily from the shallow soil and less from the deep soil. Plants in transitional‐phase drew a considerable fraction of water from canopy humus soil. This plasticity of source‐water uptake to cope with radical changes in rooting environment is likely the key feature enabling hemiepiphytic species to thrive and successfully establish in the tropical rainforests.
