Seedling regeneration after a high intensity wildfire was assessed in a mixed forest dominated by Eucalyptus species andCallitris endlicheri (Parl.) F.M.Bailey. Patternswere compared against the ‘slow seedling’or ‘tortoise-and-hare’ theory of competitive interactions betweengymnosperms andangiosperms.Browsing effectswere documentedusing fenced plots, and seedling density, mortality and height w...

Eucalyptus is the second most planted tree on earth. Despite this ranking, its mature breeding programs, clonal propagation and deployment and short rotation time make it a leading target for biotechnology improvement. The recently completed eucalyptus genome project provides an enormous opportunity for understanding and developing new traits for eucalyptus forestry. The main obstacle for wides...

Dear Sir, We read the excellent short review article of Higgins et al. (1) on contact allergy to and the safety of eucalyptus oil with great interest. Having recently finished writing a full literature review of contact allergy to and the chemical composition of essential oils (2), we would like to give some additional information on eucalyptus oil. Also, we will address the question raised by ...

The replacement of diverse deciduous forests by eucalyptus plantations changes the timing, quality and quantity of litter inputs to streams, which has the potential to affect the activity of decomposers and thus ecosystem functioning. Here, we compared (a) the decomposition rate of alder and oak leaves incubated in deciduous and eucalyptus streams in Spain and Portugal, (b) the activity (fungal...
