Phosphorus (P)-limited plant communities are widespread and may be particularly sensitive to fire, but have received relatively little research attention in this context. We measured soil nutrient concentrations, foliar carbon (C), nitrogen (N) and P stoichiometry of understorey plants in a recently, frequently burned eucalyptus forest area in south-east Queensland, Australia, and compared these properties to an adjacent unburned area. Surface soils in the area subjected to relatively recent, frequent prescribed burning had higher P concentrations than those in the adjacent unburned area, although this did not include the \u2018available\u2019 forms of P. All plant species had high foliar N:P ratios, regardless of fire history, consistent with widespread P-limitation. Some species had lower foliar N:P ratios in the burned area, indicating interspecific variation in nutrient requirements and burning responses. The nutrient resorption proficiencies of a grasstree (Xanthorrhoea johnsonii Lee) were lower in the burned area, suggesting that the nutrient cycling of this species was made less conservative by burning. The stoichiometric patterns observed in the responses of plants to prescribed burning highlight the significance of fire in this P-impoverished plant community, and suggest the potential value of stoichiometric approaches in fire ecology.", "keywords": ["580", "Agricultural", "ecological stoichiometry", "Forest meteorology.

Thinning of native forests helps to preserve native tree species and is more sustainable than replacing native forest stands with mono-species plantations to produce timber. This study aimed to explore the effects of native forest thinning on soil-plant carbon (C) and nitrogen (N) dynamics in two experimental sites, Esk (5\u00a0years post-thinning) and Herberton (7\u00a0years post-thinning), situated in Queensland, Australia. The two sites had different thinning regimes. The final stocking rates varied between 75 and 200 stems ha\u22121 at Esk and between 250 and 400 stems ha\u22121 at Herberton. The thinned plots were compared to un-thinned plots. Soil samples were collected to measure labile C and N. Leaf samples were collected from C. variegata and C. citriodora in Esk and Herberton respectively. Thinning did not change soil total C, total N, \u03b415N and inorganic N at either Esk or Herberton. However, at Esk, intensive thinning resulted in decreases in water soluble total N (WSTN). Foliar \u03b413C did not vary with respect to thinning whereas foliar \u03b415N values were more enriched in thinned areas than those of un-thinned plots. The stepwise linear regression indicated that both foliar total N and \u03b415N were explained mainly by soil TN and WSTN. Thinning did not change soil C and N most likely due to the retention of thinned materials on site and their incorporation into soil. Foliar \u03b413C was not thinning-dependent due to homeostatic maintenance of the ratio of intercellular to ambient CO2 concentrations during photosynthesis. In our study, soil N was not a limiting factor for foliar N, however, foliar N was mainly driven by WSTN which may foreshadow a possible N limitation in severely thinned plots in the long term. We conclude that forest thinning does not decrease soil C and N availability in native Corymbia forests for several years post-thinning if the thinned materials are retained on site.", "keywords": ["570", "Corymbia spp", "Inorganic nitrogen", "stable isotopes", "veterinary and food sciences", "eucalyptus spp", "Other environmental sciences not elsewhere classified", "FoR 06 (Biological Sciences)", "Stable isotopes", "Farm forestry", "580", "Agricultural", "farm forestry", "FoR 07 (Agricultural and Veterinary Sciences)", "inorganic nitrogen", "04 agricultural and veterinary sciences", "15.

Appropriate species compositions and spacing regimes are critical to achieve ecosystem benefits and improve yields of all the component crops. Cocoa (Theobroma cacao) is an important cash crop globally but it requires shade for survival and growth. However, the effects of shade-tree species composition and spacing regime on nutrient cycling in cocoa plantations are not well understood. This study investigated the effects of shade tree species and spacing regimes on soil and plant nutrient availability at 8 years after plantation establishment in Papua New Guinea. Three cocoa intercropping systems were established in which T. cacao was planted with either a non-legume timber tree, Canarium indicum, or a legume non-timber tree, Gliricidia sepium. The shade-tree spacing regimes included either 8 m \u00d7 16 m or 8 m \u00d7 8 m in the Theobroma + Canarium plantations. There was an ongoing thinning regime in the Theobroma + Gliricidia plantation, with a final shade-tree spacing of 12 m \u00d7 12 m. Soil total carbon (TC) and total nitrogen (TN) were significantly higher in the Theobroma + Gliricidia plantation with 12 m \u00d7 12 m spacing and the Theobroma + Canarium plantation with 8 m \u00d7 16 m spacing than in the Theobroma + Canarium plantation with 8 m \u00d7 8 m spacing. Foliar TN and P were correlated with soil TN and P, respectively, whereas no correlation was detected between soil and leaf K concentrations. Foliar TN, P and K were under ideal concentrations for T. cacao in all of the plantations. The Theobroma + Gliricidia plantation had higher soil water extractable phosphorus (P) than the two Theobroma + Canarium plantations, probably due to frequent pruning of the G. sepium trees. Foliar C isotope composition (\u03b413C) of T. cacao suggested that T. cacao close to G. sepium or close to C. indicum with spacing of 8 m \u00d7 16 m and 8 m \u00d7 8 m had similar light interception. However, increased C. indicum spacing increased the light interception of T. cacao trees that were not planted next to C. indicum. This study indicated that non-legume timber trees with an optimized spacing regime can be used as overstorey shade trees for T. cacao. However, our study indicated all three plantations required fertilisation and better nutrient management.", "keywords": ["571", "stable isotopes", "FoR 16 (Studies in Human Society)", "Canarium indicum", "Soil fertility", "Gliricidia sepium", "333", "630", "Papua New Guinea", "veterinary and food sciences", "Stable isotopes", "2.
