Abstract

MANSUR, M., SALAMAH, A., MIRMANTO, E. & BREARLEY, F. Q. 2022. Nutrient concentrations in three Nepenthes species (Nepenthaceae) from North Sumatra. Reinwardtia 21(2): 55‒62. — Nepenthes is a genus of carnivorous plants that are unique ornamental plants, but their nutrient concentration relationships have not been studied much, especially in endemic species on the island of Sumatra. So far, the analysis of the nutrient concentration in Nepenthes is mostly limited to leaves. There are few reports of nutrient concentrations in the pitcher fluid and the soil around where it grows. Leaves, pitcher fluid, and soil around the growth sites of each species i.e., Nepenthes sumatrana, N. spectabilis, and N. tobaica, from North Sumatra province were collected for nutrient analyses (N, P, K, Ca, Mg, and Na). The results showed that the nutrient concentrations in the leaves and pitcher fluid in the three Nepenthes species were generally low with those in the leaves greater than in the pitcher fluid. The concentration of nutrients in the leaves of N. sumatrana (lowland species) was least (except for N and Na) when compared to N. spectabilis and N. tobaica (highland species), likely reflecting the poorly fertile soil. In contrast, the nutrient concentration in the pitcher fluid of N. sumatrana was greater than N. spectabilis and N. tobaica. When compared across an extensive data set, we show that leaf N does not change with elevation, whereas P declines and the N:P ratio increases with elevation, suggesting that Nepenthes plants are obtaining sufficient N from prey at higher elevations.

Abstract

MANSUR, M & KARTAWINATA, K. 2017. Phytosociology of a Lower Montane Forest on Mt. Batulanteh, Sumbawa, Indonesia. Reinwardtia 16 (2): 77-92. — While Indonesia’s forests are globally known for their high species diversity but many regions remain little known to investigate the tree community in a lower montane forest at Mt. Batulanteh in Sumbawa. We subjectively laid out plots of 1,800 m2 each, two in secondary forests and one in a disturbed primary forest. All stems over 5 cm diameters were measured and identified. In the plot of 0,54 hectare, we recorded 723 individuals, representing 78 species, 60 genera and 33 families. Estimated volume of boles was 183.2 m3/0.54 ha, biomass was 220.1 tons/0.54 ha, carbon stock was 110.0 tons/0.54 ha and CO2 sequestration was 403.1 ton/0.54 ha. The forest at Mt. Batulanteh is classified as Garcinia-Cryptocarya association consisting of Micromelum-Cinnamomum subassociation. Dipterocarpus-Calophyllum subassociation and Garcinia-Syzygium subassociation. Dominant species were Micromelum minutum (IV=27.24), Mallotus philippensis (IV=26.2), Cryptocarya ferrea (IV=24.71) and Cinnamomum burmanni (IV=23.81) in Plot 1, Dipterocarpus retusus (IV=77.4) and Calophyllum soulattri (IV=24.21) in Plot 2, and Garcinia celebica (IV=34.86) and Syzygium sp. 1 (IV=34.76) in Plot 3. Dipterocarpus retusus was unique of having restricted distribution. Fagaceae, typical family in montane forests, was absent. Shannon’s diversity index was low (H '= 1.61). It can be concluded that the plots do not constitute a representative of Mt. Batulanteh and the surrounding forests, but they were sufficient to provide an illustration of the forests locally. The diameter class distribution indicated that the forests were regenerating. They were developing secondary forest and regenerating disturbed primary forest; slow successions were in the process and could be enhancedby ecological restoration. Further botanical explorations in poorly known regions of Sumbawa should be intensified further.
