Thermal Thresholds

Exceeding thermal thresholds causes irreversible damage and ultimately loss of leaves. The lowland tropics are among the warmest forested biomes, but little is known about heat tolerance of tropical forest species. We surveyed leaf heat tolerance of sun-exposed leaves from 147 tropical lowland and pre-montane forest species by determining the temperatures at which potential photosystem II efficiency based on chlorophyll a fluorescence started to decrease (T) and had decreased by 50% (T). T averaged 46.7°C (5–95 percentile: 43.5–49.7°C) and T averaged 49.9°C (47.8–52.5°C). Heat tolerance partially adjusted to site temperature; T and T decreased with elevation by 0.40°C and 0.26°C per 100m, respectively, while mean annual temperature decreased by 0.63°C per 100m. The phylogenetic signal in heat tolerance was weak, suggesting that heat tolerance is more strongly controlled by environment than by evolutionary legacies. T increased with the estimated thermal time constant of the leaves, indicating that species with thermally buffered leaves maintain higher heat tolerance. Among lowland species, T increased with leaf mass per area, so species with structurally more costly leaves reduce the risk of leaf loss during hot spells. These results provide insight in interspecific variation in heat tolerance at local and regional scales.

Distinguishing Features

Soils of the indigenous forest-fynbos interface in the Southern Cape were sampled for chemical and physical analyses and compared by means of anlyses of variance. Correlations among soil variables were investigated by subjecting the correlation matrices to cluster analysis. Soil data were compared with that of fynbos and tropical forest areas. Morphological and physiological features of the forest vegetation, such as evergreenness, sclerophylly, phenolic compounds in the leaves, mast fruiting (i.e. gregarious fruiting) and root mat, were correlated with the soil nutritional status.
