“…Despite this potential Australia's dominant tree genus, Eucalyptus L'Herit., has received little dendroclimatological attention (Brookhouse 2006). This is due to the belief that eucalypts are not suited to dendrochronological study (Dunwiddie and LaMarche 1980;LaMarche et al 1979;Ogden 1978).…”

We investigated crossdating and climate sensitivity in tree-ring series from Eucalyptus delegatensis Baker, R.T. and E. obliqua L'Herit. We first visually crossdated the measured ring width series and then independently verified this crossdating using Xmatch and cross-correlation significance tests. Crossdating was verified in 28 of the 32 study trees. Crossdating success differed between E. delegatensis and E. obliqua. In E. delegatensis crossdating success appears to be related to tree dominance and elevation. In E. obliqua radial azimuth appears to affect crossdating success. We developed two chronologies for each of the species studied. The first of these chronologies was based on all visually crossdated radii and the other on radii for which crossdating had been independently verified. Signal strength was higher in the verified chronologies. Correlation analysis between the verified chronologies and climate data revealed no significant correlation between precipitation and ring width for either species. E. obliqua ring width was significantly correlated with mean minimum and maximum air temperature and vapour pressure deficit during summer of the growing season. The E. delegatensis chronology was significantly correlated with air temperature and frequency of frost during the preceding winter. Ring width in both species was significantly correlated with air temperature during the preceding summer. Potential physiological explanations for these results are discussed. Further study is required to verify the results of climatological analysis and to explore the causes of variation in signal strength within and between trees. Communicated by M. Adams M.

“…Despite the apparent potential of E. pauciflora for dendroclimatology-the species is widely distributed, forms mono-specific stands at the alpine timberline (1,850-1,900 m) (Boland et al 1992) exhibits a high degree of sensitivity to temperature (Slatyer and Morrow 1977) and forms distinct annual tree rings (Green 1967;Banks 1982)-previous analyses of tree-ring data from the species have not identified a sensitivity to climate (Brookhouse 2006). One explanation for this result, initially proposed by Morrow and LaMarche (1978), lies in the growth-dampening impact of insect folivory.…”

“…For example, Brookhouse (2006) reports that of the four dendroclimatological studies conducted on E. pauciflora, two (Keith 1982, Strasser 1992) comprise sample material from sites well within the species' temperature and soil moisture tolerance limits. The two remaining studies (Griffith 1973;Smith 1997) utilise sample material collected at or near the treeline.…”

We examine climate sensitivity in tree-ring chronologies from Eucalyptus pauciflora Sieb. ex Spreng at three elevations-1,350, 1,475 and 1,600 m above the sea level. Consistent with the principle that the sensitivity of tree-ring chronologies increases with proximity to the limits of tree growth, statistics reflecting chronology reliability increased with elevation. Climatological analyses of the three elevation classes revealed that whilst ring width is significantly and positively correlated with maximum air temperature during spring (September-November) in the chronology from the highest elevation class, significant correlations with maximum temperature are not present at low elevations. Similarly, whilst ring width in the chronology from 1,350 m was significantly and positively correlated with precipitation during late summer and early autumn, no significant correlations are evident at higher elevations. Our results illustrate the importance of careful site selection in dendroclimatological studies of eucalypts and demonstrate the potential of E. pauciflora for climatological studies.

The worldwide status of phasmids (Insecta: Phasmida) as pests of agriculture and forestry, with a generalised theory of phasmid outbreaks

Stick insects have been reported as significant phytophagous pests of agricultural and timber crops since the 1880s in North America, China, Australia and Pacific Islands. Much of the early literature comes from practical journals for farmers, and even twentieth Century reports can be problematic to locate. Unlike the plaguing Orthoptera, there has been no synthesis of the pest status of this enigmatic order of insects. This paper provides a literature synthesis of those species known to cause infestation or that are known to damage plants of economic importance; summarises historical and modern techniques for infestation management; and lists known organisms with potential for use as biological control agents. A generalised theory of outbreaks is presented and suggestions for future research efforts are made.
