This study aimed to contribute to the investigation into the nursing effects promoted by&nbsp;<i>Araucaria angustifolia<\/i>&nbsp;during the process of forest expansion over grasslands in southern Brazil. Air temperature and humidity, and soil chemistry were evaluated beneath the canopy of isolated trees of&nbsp;<i>A. angustifolia<\/i>, and compared with values in adjacent grassland areas and under the canopy of the shrub&nbsp;<i>Baccharis uncinella.<\/i>&nbsp;Milder summer temperatures and vapour pressure deficits were measured under&nbsp;<i>Araucaria<\/i>&nbsp;and&nbsp;<i>Baccharis<\/i>&nbsp;compared with open grassland. There were also ameliorating effects on soil chemistry under individuals of these two species, but these were more pronounced for&nbsp;<i>Araucaria<\/i>&nbsp;than for&nbsp;<i>Baccharis.<\/i>&nbsp;The results suggest that the large number of seedlings commonly found beneath the canopy of&nbsp;<i>Araucaria<\/i>&nbsp;is due not only to perching, but also to nursing, through the amelioration of environmental conditions.\n\t<\/p>\n<\/div>\n<p>\n\t<a href=\"http:\/\/dx.doi.org\/10.1080\/0028825X.2014.979837\"><em><strong>Read more<\/strong><\/em><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Abstract The expansion of forests over natural grasslands is observed in many parts of the world.
