| germination requirements and responses to leaf litter of four species of eucalypt. | we studied how the responses of four species of eucalypt to leaf litter related to their germination responses to light and water availability. two of the species (eucalyptus obliqua and e. baxteri) have a mesic distribution, while the other two (e. oleosa, and e. incrassata) are more xerophytic. we studied the effect of litter on emergence of the four species in a glasshouse experiment. litter did not affect the emergence of e. incrassata and e. oleosa, but enhanced the emergence of e. obliqua ... | 1996 | 28307385 |
| uptake of nitrate, ammonium and glycine by plants of tasmanian wet eucalypt forests. | a central assumption of ecosystem n cycling has been that organic n must be converted to inorganic n to be available for plant uptake, but this has been questioned by recent studies. we examined uptake of nitrate, ammonium and the amino acid glycine in three species from eucalyptus obliqua l'her. wet forest in tasmania, south-eastern australia, to test the hypothesis that all three species can take up glycine, and to compare rates of glycine uptake with rates of uptake of nitrate and ammonium up ... | 2007 | 17241983 |
| priority effects produced by plant litter result in non-additive competitive effects. | litter may indirectly affect competitive interactions. it is not clear whether these changes are additive or non-additive indirect effects. non-additivity could result from: (1) changes in biomass allocation patterns by competitors towards organs not directly involved in resource acquisition (e.g., longer hypocotyls); (2) changes in the proportion of different functional groups (e.g., grasses and forbs) that possess different competitive abilities; or (3) through priority effects caused by subtl ... | 2008 | 18654801 |
| environmental effects on growth phenology of co-occurring eucalyptus species. | growth is one of the most important phenological cycles in a plant's life. higher growth rates increase the competitive ability, survival and recruitment and can provide a measure of a plant's adaptive capacity to climate variability and change. this study identified the growth relationship of six eucalyptus species to variations in temperature, soil moisture availability, photoperiod length and air humidity over 12 months. the six species represent two naturally co-occurring groups of three spe ... | 2014 | 24170140 |
| structural adjustments in resprouting trees drive differences in post-fire transpiration. | following disturbance many woody species are capable of resprouting new foliage, resulting in a reduced leaf-to-sapwood area ratio and altered canopy structure. we hypothesized that such changes would promote adjustments in leaf physiology, resulting in higher rates of transpiration per unit leaf area, consistent with the mechanistic framework proposed by whitehead et al. (whitehead d, jarvis pg, waring rh (1984) stomatal conductance, transpiration and resistance to water uptake in a pinus sylve ... | 2014 | 24536069 |
| environmental effects on germination phenology of co-occurring eucalypts: implications for regeneration under climate change. | germination is considered one of the important phenological stages that are influenced by environmental factors, with timing and abundance determining plant establishment and recruitment. this study investigates the influence of temperature, soil moisture and light on the germination phenology of six eucalyptus species from two co-occurring groups of three species representing warm-dry and cool-moist sclerophyll forests. data from germination experiments were used to calibrate the germination mo ... | 2015 | 25409871 |
| eucalyptus obliqua seedling growth in organic vs. mineral soil horizons. | eucalyptus obliqua, the most widespread timber tree in tasmania, is a pioneer after fire which can eliminate the organic layer of forest soil, exposing the underlying mineral soil. we compared seedling growth, mycorrhiza formation, and mineral nutrient limitation in organic layer vs. mineral soil. we grew e. obliqua seedlings separately in pots of organic layer and mineral soil in a glasshouse. additional treatments of organic soil only, involved fully crossed methyl-bromide fumigation and ferti ... | 2015 | 25750650 |
