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...

Eucalyptus plantations are frequently used for the establishment of bee yards. This study was carried on at Fazenda Brejão, northwestern region of the State of Minas Gerais, Brazil. This farm is covered both with native Cerrado vegetation (Brazilian savanna) and eucalyptus plantations. This paper reports on the botanic origin of pollen pellets and honey collected from honeybee (Apis mellifera) ...

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...

فعالیت‌های فشرده بشر از جمله شهری، صنعتی، کشاورزی و ترافیک به آلودگی مناطق تحت آبیاری، سواحل و بسیاری از مناطق دیگر از طریق آفت کشها، نیتراتها، آلاینده‌های آلی و فلزات سنگین و ... منجر شده‌است. در چنین مناطقی استفاده ‌از گیاهانی که بتوانند عناصر سنگین را ذخیره نمایند، می‌تواند از نظر اقتصادی مؤثر باشد. این تحقیق به منظور بررسی و مقایسه ‌اثرات چهار عنصر سنگین مس (Cu)، روی (Zn)،  کادمیم (Cd)، سرب...

The evolutionary history of Eucalyptus and the eucalypts, the larger clade of seven genera including Eucalyptus that today have a natural distribution almost exclusively in Australasia, is poorly documented from the fossil record. Little physical evidence exists bearing on the ancient geographical distributions or morphologies of plants within the clade. Herein, we introduce fossil material of ...

Mycosphaerella species are well-known causal agents of leaf diseases on many economically and ecologically important plant species. In Uruguay, a relatively large number of Mycosphaerellaceae and Teratosphaeriaceae are found on Eucalyptus, but nothing is known of these fungi on native Myrtaceae. The aim of this study was to identify Mycosphaerellaceae and Teratosphaeriaceae species associated w...

Eucalyptus oil has been reported effective in reducing pain, swelling, and inflammation. This study aimed to investigate the effects of eucalyptus oil inhalation on pain and inflammatory responses after total knee replacement (TKR) surgery. Participants were randomized 1 : 1 to intervention group (eucalyptus inhalation group) or control group (almond oil inhalation group). Patients inhaled euca...
