“…As is to be expected, phytogeographic similarities on the generic level are greatest with Andean forests ) and, to a lesser extent, with forested mountain ranges N of Costa Rica, like the Guatemalan Sierra de los Cuchumatanes (Islebe & Kappelle 1994). Quercus, for instance, also forms extensive forests in the northern Andes (Cuatrecasas 1934;Vega 1964;Lozano & Torres 1974), (sub)tropical Himalayas (Saxena & Singh 1982) and on Java and Borneo (Werner 1986;Kitayama et al 1993), but is absent in Sri Lankan montane forests (Werner 1986). On the contrary, they are known to occur in a number of other equatorial countries.…”

“…Tropical montane fagaceous forests are certainly not restricted to Central America. Nothofagus dominates large forest areas in Chile (Veblen et al 1981) and in Papua New Guinea (Read et al 1990), while Castanopsis and Lithocarpus are major constituents in (upper) montane rainforest on Borneo and Sumatra, respectively (Ohsawa et al 1985;Bratawinata 1986, Kitayama et al 1993.

Altitudinal zonation of montane Quercus forests along two transects in Chirrip� National Park, Costa Rica

1995

Abiotic and vegetation data were collected along two altitudinal transects through mature montane Quereus forests on the Pacific and Atlantic slopes of Costa Rica's Chirrip6 Massif. Between 2000 and 3200 m asl twenty-four 0.05 ha forest plots were selected at altitudinal intervals of 100 m, and eight soil profiles were described at intervals of 200 m. A TWINSPAN classification aided in the determination of eight zonal forest communities on the basis of their floristic composition. They are grouped in two sets of four: (i) the palm-rich lauraceous-fagaceous Lower Montane Mollinedia-Quercus Forests (20(0)-2600 m asl) and (ii) the bamboo-rich myrsinaceous-fagaceous Upper Montane Schefflera-Quercus

Plant diversity and foliar elemental profiles in relation to soil chemistry and altitude on ultramafic edaphic islands in Kinabalu Park (Malaysia)

This research project was multifaceted and aimed to develop an understanding of how plant diversity and foliar elemental chemistry interact with soil chemistry and altitude on ultramafic outcrops in Kinabalu Park (Sabah, Malaysia, Borneo Island). The research site, Kinabalu Park, is the world's most species-rich hotspot (>5000 plant species in <1200 km 2 ), and the presence of widely-scattered ultramafic outcrops is thought to have stimulated plant evolution in the area. Tambuyukon host exceptionally species-rich plant communities, but also contribute to the extreme stunting of this vegetation. The vegetation of serpentinite soils, however, are characterised by trees in the family Casuarinaceae and is species-poor. Although vastly different chemically, both hypermagnesian and serpentinite soils host high levels of ultramafic obligate species. In contrast, obligate ultramafic species are virtually absent in the lowland forest, but the combination of a number of dipterocarps is a characteristic of these forests.The foliar elemental profiles of plants growing on ultramafic soils were characterised by higher concentrations of Fe, Mg, Co, Cr, and Ni, but lower concentrations of Ca, K and P. This research identified hyperaccumulator behaviour in a range of plant species: Al >1000 µg/g (38 spp.), Mn >10 mg/g (7 spp.), Cu >300 µg/g (1 sp.), Cr > 300 µg/g (3 spp.), Co >300 (3 spp.), Ni >1000 µg/g (24 spp.) and Zn >3000 µg/g (2 spp.) The foliar frequency distribution of Ni follows a distinct bimodal distribution, with the modes ('non-accumulators' and 'hyperaccumulators') separated at approximately 850 µg/g Ni (the lower limit of the 'hyperaccumulator mode'). This indicates a distinct ecophysiological trait, as opposed to just the upper tail of a normal frequency distribution.In Sabah, Ni hyperaccumulation occurs most frequently in the Order Malpighiales (families: 3 Dichapetalaceae, Phyllanthaceae, Salicaceae, Violaceae), and is particularly common in the Phyllanthaceae (genera Phyllanthus, Glochidion). Ni concentrations belong to the highest recorded globally attaining up to 2.4% in foliage (Psychotria sarmentosa complex) and up to 16.9% in the phloem exudate (Phyllanthus balgooyi). The phloem tissue of many of these species appears to act as a 'Ni-sink', which could function to re-distribute Ni to emerging shoots, hence potentially aiding insect herbivory-protection, although specialist Ni-tolerant insects were also found. Ni hyperaccumulators were localised in successional habitats on serpentinite soils with active mineral weathering. These soils showed a 'threshold response' with >20 µg/g carboxylic extractable Ni or > 630 µg/g pseudo-total Ni, and pH >6. The soil chemistry in this zone is extreme, and the most probable cause for the stunted vegetation.Carnivorous Nepenthes provide examples of ultramafic obligate and endemic species, and N. rajah, N. villosa, N. burbidgeae and N. edwardsiana were studied. The results showed that these species are restricted to a very unusual combination of factors: extremely...
