“…The soil nutrient concentrations are low, though only N could be described as very low in comparison with other published analyses. Despite this, the C:N ratio of the soil is not as high as data published for heath forests in Southeast Asia (Yamakura & Sahunalu 1990). NATURE OF THE VEGETATION.-The heath was clearly dominated by sderophyllous shrubs with extremely nutrient-poor foliage, though the soil was not as impoverished as might be predicted from the foliar analyses.…”

“…Similarly, positive trends and/or slightly convex curves were also identified in deciduous forests by Schuster and Diekmann [4]. The C/N ratio of soil organic matter was related to a nitrogen immobilization and mineralization during decomposition by microorganisms [18,58]. Alder forests of European temperate zone create two main vegetation groups, which vary in their environmental conditions, including their affinity for soil substrates.…”

“…The effect of soil phosphorus on species richness is much more ambiguous because of interactions with other covariant factors modifying the supply, chemical form and availability of nutrients (e.g., soil reaction, chemistry of geological substrates). The carbon to nitrogen (C/N) ratio of soil organic matter is a useful indicator of site quality with effects on both forest species composition and richness [18,19]. However, plant species richness in floodplain forests is also driven by several other environmental factors such as soil moisture and reaction, landscape configuration and dynamic of water regime [20][21][22].…”

Soil nitrogen and phosphorus are commonly limiting elements affecting plant species richness in temperate zones. Our species richness-ecological study was performed in alder-dominated forests representing temperate floodplains (streamside alder forests of Alnion incanae alliance) and swamp forests (alder carrs of Alnion glutinosae alliance) in the Western Carpathians. Species richness (i.e., the number of vascular plants in a vegetation plot) was analyzed separately for native and alien vascular plants in 240 vegetation plots across the study area covering Slovakia, northern Hungary and southern Poland. The relationship between the species richness of each plant group and total soil nitrogen content, plant-available phosphorus and carbon to nitrogen (C/N) ratio was analyzed by generalized linear mixed models (GLMM) with Poisson error distribution and log-link function. The number of recorded native and alien species was 17-84 (average 45.4) and 0-9 (average 1.5) species per plot, respectively. The GLMMs were statistically significant OPEN ACCESSForests 2015, 6 3502(p ˂ 0.001) for both plant groups, but the total explained variation was higher for native (14%) than alien plants (9%). The richness of native species was negatively affected by the total soil nitrogen content and plant-available phosphorus, whereas the C/N ratio showed a positive impact. The alien richness was predicted only by the total soil nitrogen content showing a negative effect.

“…soil analysis from primary forest at Bukit Timah Nature Reserve, Table 4) led to the loss of nutrients and much of the top-soil in these sites (Panton 1955). The exceedingly high C/N ratios of the adinandra belukar, higher than the values for many South-East Asian forests (see Yamakura & Sahunalu 1990), would seem to indicate very low nitrogen mineralization rates. There is a build up of litter on the floor of the adinandra forest to considerably greater depths than can be observed in primary rain forest.…”

Adinandra belukar: an anthropogenic heath forest in Singapore

1992

Adinandra belukar is a species-poor forest dominated by Adinandra dumosa (Theaceae) found in Singapore and southern Peninsular Malaysia. It is the product of secondary succession after exhaustive agricultural exploitation on land cleared of primary lowland rain forest. A high degree of similarity in vegetation between different sites was found for seven 225 m 2 plots in adinandra belukar in Singapore.Adinandra dumosa was dominant or codominant in all plots, generally found in association with the woody species Dillenia suffruticosa, Fagraea fragrans, and Rhodamnia cinerea, the climber Gynochthodes sublanceolata, the fern Dicranopteris Iinearis and the terrestrial orchid Bromheadia finlaysoniana. All sites had extremely acidic (pH 3.3-3.9) surface (0-20 cm) mineral soils with very low total nitrogen (0.06-0.14~o) and total phosphorus (11-29 #g g -l ) contents and very high carbon/nitrogen ratios (33-48). Adinandra belukar is interpreted as a heath forest because of its floristic and physiognomic similarities with this forest formation.Nomenclature: follows Turner, Chua and Tan (1990), A checklist of the native and naturalized vascular plants of the Republic of Singapore.
