Spatial relations and population structure of a dominant tree along a treeline ecotone in the Tropical Andes: interactions at gradient and plant-neighbourhood scales
(Plant Ecology and Diversity 6(3-4): 343-353Venezuela, 2014)
Self-replacement after small-scale partial crown dieback in austral Nothofagus dombeyi forests affected by an extreme drought
(National Research Council Canada-NRC Research Press, 2018-01)
The spectrum of structural response in drought-induced mortality (degree of partial crown mortality) could play a key role in pervasive changes in plant composition, as individual openings could reset self-replacement ...
Effects of natural small-scale disturbances on below-canopy solar radiation and regeneration patterns in an old-growth nothofagus betuloides forest in tierra del fuego, chile
(2010)
Over the last decade a shelterwood system promoting natural regeneration has been applied in the southern Chilean old-growth Nothofagus forests. However, most of these forests are naturally uneven-aged, and the effect of ...

Pine invasion impacts on plant diversity in patagonia: invader size and invaded habitat matter
Conifers, which are widely planted as fast growing tree crops, are invading forested and treeless environments across the globe, causing important changes in biodiversity. However, how small-scale impacts on plant diversity ...
Patch size, shape and edge distance influence seed predation on a palm species in the Atlantic forest
(2016-04-01)
Seed predation is an important ecological process that affects the abundance, diversity and distribution of plant species, and it is known to be influenced by defaunation and forest fragmentation. Most studies on seed ...
Efeitos de florestas ripárias em restauração na estrutura de comunidades de macroinvertebrados aquáticos e nas taxas de decomposição de matéria orgânica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciências Ambientais - PPGCAmCâmpus São Carlos, 2018-08-03)
Riparian forests play a very important role in protecting watercourses and represent an energy source for the aquatic communities in low-order streams. Therefore, the input of allochthonous material from these ecosystems ...
