A new species of chrysomeline leaf beetle, Paropsisterna selmani Reid & de Little, is described, including all larval in-stars. This species, native to Australia, is now a significant pest of Eucalyptus plantations in Australia and Ireland, and has been recorded in southern England. Its occurrence in the British Isles represents the first record of establishment of a eucalypt feeding chrysomeli...

Nitrogen (N) fertilization is necessary to sustain productivity in eucalypt plantations, but it can increase the risk of greenhouse gas emissions. However, the response of soil greenhouse gas emissions to N fertilization might be influenced by soil characteristics, which is of great significance for accurately assessing greenhouse gas budgets and scientific fertilization in plantations. We cond...

The objective of this work was to evaluate height-diameter, volumetric, and taper models estimate the height, volume, bole profile trees eucalypt clones (Eucalyptus grandis × Eucalyptus urophylla) in an agrosilvopastoral system. Data were collected from permanent plots eight year-old system, composed by three (VE01, VE06, VE07), located municipality Coronel Xavier Chaves, state Minas Gerais, Br...

A study was undertaken to explore the content and composition of volatile oil from decaying leaves of lemon-scented eucalypt (Eucalyptus citriodora Hook.) not analyzed earlier. GC and GC-MS analysis of the oil (yield 0.6%) revealed the monoterpenoid nature with citronellal (52.2%), citronellol (12.3%) and isoisopulegol (11.9%) as the major constituents. Overall, 17 components were identified th...

We construct a model of a multispecies forest that is often affected by major fires and explicitly incorporates life-history attributes of trees that are related to fire—flammability and susceptibility to fire. The model is used to explore coexistence mechanisms in forests; two fire-dependent coexistence mechanisms were identified. The first allows coexistence along a temporal axis since the la...
