| water relations and growth of shrubs before and after fire in a semi-arid woodland. | plant water relations and shoot growth rate of shrubs resprouting after fire or unburnt were measured in a semi-arid poplar box (eucalyptus populnea) shrub woodland of eastern australia. in vegetation unburnt for about 60 years, the dawn xylem water potential (ψx) of the dominant shrub species was about-1.0 mpa when the soil was wet and-8.0 mpa when the soil was very dry. at any one time, the dominant shrub species,eremophila mitchellii, e. sturtii, geijera parviflora andcassia nemophila, were s ... | 1992 | 28313565 |

| estimating stand transpiration in a eucalyptus populnea woodland with the heat pulse method: measurement errors and sampling strategies. | sap flow measurement techniques, such as the heat pulse (compensation) method, are practical means for estimating the water use of individual trees and are often the only reasonable alternative for measuring forest and woodland transpiration in complex heterogeneous terrain. the need to scale estimates of water use from a sample of individual stems to a stand (population) of known area may be satisfied by applying scalars of flux based on tree size or domain. we estimated the aggregate errors in ... | 1995 | 14965961 |
| a morphological cline in eucalyptus: a genetic perspective. | the putative hybrid zone between eucalyptus populnea and e. brownii is examined using morphological and molecular techniques. this species complex displays continuous morphological variation across the study area, which has been previously interpreted as the product of hybridization between allopatric species. a microsatellite analysis indicates that there was little genetic structuring across the morphological cline and only low levels of population differentiation. the nested clade analysis of ... | 2003 | 14629382 |
| drought × co2 interactions in trees: a test of the low-intercellular co2 concentration (ci ) mechanism. | models of tree responses to climate typically project that elevated atmospheric co2 concentration (eca ) will reduce drought impacts on forests. we tested one of the mechanisms underlying this interaction, the 'low ci effect', in which stomatal closure in drought conditions reduces the intercellular co2 concentration (ci ), resulting in a larger relative enhancement of photosynthesis with eca , and, consequently, a larger relative biomass response. we grew two eucalyptus species of contrasting d ... | 2016 | 26526873 |
