Eucalyptus globulus is one of the most widely planted temperate hardwood species in the world, and in Australia there are 538,000 hectares growing in plantations. Although it has been reported as invasive, quantification of E. globulus invasion is rare. We conducted surveys at two geographic scales to assess the level of, and factors influencing, wildling(More)
Eucalyptus globulus is native to Australia and currently one of the most cultivated hardwood species worldwide. The adaptation of E. globulus to fire-prone habitats has been linked to fire as a driver for regeneration and subsequent naturalization in Mediterranean-type regions. We studied the effect of fire on capsules and encapsulated seeds of E. globulus(More)
Tasmanian blue gum (Eucalyptus globulus) has been increasingly used in forestry outside its native range, and is nowadays one of the most important pulpwood species in the world. E. globulus has great economic importance in many countries, and in Portugal it has recently become the most widespread tree species. However, there is also an increasing concern(More)
This study focused on the therapeutic effect of a propolis SLNC 106 (PI) extract on experimental colitis. Wistar adult rats received 0.8 mL rectal dose of one of the following solutions: saline (group S), 20 mg TNBS in 50% ethanol (group TNBS), 20 mg TNBS in 50% ethanol and propolis extract in saline (group TNBS-P), propolis extract in saline (group SP),(More)
We studied the effect of dense populations of red and fallow deer on a burned Mediterranean plant community in Portugal. We sampled a set of 12 open and 12 fenced plots 2, 3, 4, and 8 years after fire occurrence. Each plot was sub-sampled using a quadrat grid to estimate the relative plant frequency (proportion of quadrats with plants). The effect of deer(More)
This paper deals with occupational accident patterns of in the Portuguese Extractive Industry. It constitutes a significant advance with relation to a previous study made in 2008, both in terms of methodology and extended knowledge on the patterns' details. This work uses more recent data (2005– 2007) and this time the identification of the ''typical(More)
