Validity and reliability of a new incremental step test for people with chronic...
Vilarinho, Rui; Serra, Lúcia; Águas, Ana; Alves, Carlos; Silva, Pedro Matos; Caneiras, Cátia; Mesquita Montes, AntónioIncremental step tests (IST) can be used to assess exercise capacity in people with chronic obstructive pulmonary disease (COPD). The development of a new step test based on the characteristics of the incremental shuttle walk test (ISWT) is an important study to explore. We aimed to develop a new IST based on the ISWT in people with COPD, and assess its validity (construct validity) and reliability, according t...
Microsite Drivers of Natural Seed Regeneration of Eucalyptus globulus Labill. i...
Águas, Ana; Matias, Hugo; Rodrigues, Abel; Bailey, Tanya; Silva, Joaquim; Rego, Francisco CastroFire regimes are changing in several regions of the world. In those regions, some exotic species may be better adapted to new regimes than the native species. This study focused on identifying the microsite characteristics associated with the occurrence of post-fire Eucalyptus globulus regeneration from seeds, outside the species native-range. This information is important in helping to assess the naturalizatio...

Fire effects on litter chemistry and early development of Eucalyptus globulus
Águas, Ana; Incerti, Guido; Saracino, Antonio; Lanzotti, Virginia; Silva, Joaquim S.; Rego, Francisco C.; Mazzoleni, Stefano; Bonanomi, GiulianoBackground and aim Fires affect what happens to litter in ecosystems. Biological and chemical effects of burnt litter on plants are not as of yet fully understood. We aimed to assess the effects of heat-treated leaf litter on germination and seedling root growth of Eucalyptus globulus. Methods Litter from E. globulus, Acacia dealbata, Pinus pinaster, and Quercus suber was collected in Portugal, on Humic Cambiso...
Understanding the naturalization of Eucalyptus globulus in Portugal: a comparis...
Águas, Ana; Larcombe, Matthew J.; Matias, Hugo; Deus, Ernesto; Potts, Brad M.; Rego, Francisco C.; Silva, Joaquim S.Despite the potential utility of a biogeographical approach to understanding the naturalization of exotic species, studies using this approach are scarce. Eucalyptus globulus is an economically important Australian tree species that has become naturalized in a number of countries where it was introduced. Portugal is an ideal territory to study the naturalization of E. globulus owing to: a long introduction hist...
Fire effects on capsules and encapsulated seeds from Eucalyptus globulus in Por...
Santos, Patrícia dos; Matias, Hugo; Deus, Ernesto; Águas, Ana; Silva, Joaquim S.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 Labill. in the canopy and on the ground, aiming to asse...
Assessing the extent and the environmental drivers of Eucalyptus globulus wildl...
Catry, F. X.; Moreira, F.; Deus, E.; Silva, J. S.; Águas, AnaTasmanian 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 about the potential ability of eucalypts to naturally es...
Natural establishment of Eucalyptus globulus Labill. in burnt stands in Portugal
Águas, Ana; Ferreira, António; Maia, Paula; Fernandes, Paulo M.; Roxo, Luís; Keizer, Jan; Silva, Joaquim S.; Rego, Francisco C.; Moreira, FranciscoExotic tree species are increasingly common in many regions of the world and at least some species are becoming naturalized in the regions where they were introduced. Disturbances like fire may be at the origin or accelerate the naturalization of these species. Portugal holds one of the largest areas of exotic Eucalyptus globulus plantations in the world and is one of the countries most affected by forest fires...
