| After an extensive two-year long research effort, the results document the diversity of vascular plants that grow in the public spaces of Santiago, Chile. We analyze the taxonomic composition, life-forms and phytogeographic origin of the vascular flora of Santiago and, finally, we compare the results with those of urban areas in the Northern Hemisphere. We identified 508 species, 100 families, and 338 genera. The families that showed the greatest richness were Asteraceae and Poaceae. We found that at least 85.1% of the species are exotic. The life-forms are similarly represented, although chamaephytes and geophytes are poorly represented. We conclude that the composition of the urban flora of Santiago differs from that of most Northern Hemisphere cities,... |

| We studied the effect of heat shock and wood-fueled smoke on the emergence of native and exotic plant species in soil samples obtained in an evergreen matorral of central Chile that has been free of fire for decades. It is located on the eastern foothills of the Andes Range in San Carlos de Apoquindo. Immediately after collection samples were dried and stored under laboratory conditions. For each two transect, ten samples were randomly chosen, and one of the following treatments was applied: (1) heat-shock treatment, (2) plant-produced smoke treatment, (3) combined heat-and-smoke treatment, and (4) control, corresponding to samples not subjected to treatment. Twenty-seven species, representing 13 families, emerged from the soil samples. The most abundant... |
