We used a physically based ecohydrological model to predict the water balance and growth responses of a mountain ash (Eucalyptus regnans F. Muell.) forest catchment to clear-felling and regeneration. The model, Topog-IRM, was applied to a 0.53 km(2) catchment for a 3-year pretreatment period, and a 20-year period following clear-felling and reseeding of 78% of the catchment area. Simulations we...

Summary At the time of description, morphology Ptychaphelenchus eucalypticola Hodda, 2009 indicated it could be assigned to either Aphelenchoididae Skarbilovich, 1947 (Paramonov, 1953) or Parasitaphelenchidae Ruehm, 1956 (Siddiqi, 1980) within Aphelenchoidoidea 1980). Although P. was, tentatively, and remains Aphelenchoididae, its relationships with other aphelenchoids have not been reassessed,...

Karri (Eucalyptus diversicolor F. Muell.) forest is an endemic type of southwest Western Australia (SWWA), noted for having the tallest trees in region, and providing commercial, ecological conservation value. To inform management aimed at optimising these values, a thinning trial was commenced 1992. The aim this study to evaluate effects on individual tree growth, stand level growth allometry ...

Two acyl phloroglucinol compounds namely; Sideroxylonal B (1) and Macrocarpal A (2) were isolated from the Sideroxylonal-Rich Extract (SRE) of the juvenile leaves of Eucalyptus cinerea; F. Muell. ex Benth cultivated in Egypt. Identification of the isolated compounds was established on the basis of physico-chemical properties and spectral analysis (1D & 2D NMR). The two compounds were isolated f...
