Abstract: Each tropical and subtropical forest canopy species may create specific microsite conditions below its crown, which works as a filter for those species that attempt to regenerate below it. In function of the permeability or impermeability level, each canopy species could partially determine a plant community structure and composition beneath its crown projection. Therefore, present and future forest plant community biodiversity could be partially determined by the present structure of the canopy tree species c… Show more

“…These differences have relevant implication over the diversity of the understory, because each canopy woody species may create specific microsites below its crowns, which function as a biodiversity filter upon the plants that attempt to regenerate under it (GANDOLFI et al, 2007). Rich et al (1993) showed wide differences in radiation between gap and closed-canopy locations, with large increase in solar radiation in gap stations during dry months, and a decrease in photosynthetic photon flux density (PPFD) for gap stations due to vegetation regrowth, further evidence for the filter effect.…”

“…According Gandolfi et al (2007), the leaves abscission and low water availability during the dry season creates more stressful conditions for seedlings, but when the first rains return, more light and water become available and might favor seedlings under deciduous (or semi-evergreen) trees generating distinct biological responses, such as the growth or death in seedlings. Thus, this filter effect may be acting at the rehabilitated forest selecting some seedlings, maybe the exotics, and excluding others.…”

“…A grande diversidade de árvores do dossel e do estrato emergente das florestas tropicais exerce papel fundamental na criação e manutenção de microssítios particulares de regeneração, dadas as variações de altura, tamanho de copa, densidade de folhagem, épocas, intensidade (perenifólias, caducifólias e semicaducifólias) e duração do período de perda foliar (MONTGOMERY e CHAZDON, 2001;GANDOLFI et al, 2007). Além das variações de microclima resultantes dessas diferentes características das árvores do dossel (NICOTRA e CHAZDON, 1999), a riqueza de microssítios de regeneração é acentuada pelos efeitos da deposição e constituição da serapilheira nas plântulas (MOLOFSKY e AUGSPURGER, 1992;GUILLMAN e OGDEN, 2005), na germinação (VÁZQUEZ-YANEZ et al, 1990), na mineralização de nutrientes (ZINKE, 1962;MONTAGNINI e SANCHO,1990), na liberação de aleloquímicos (BORGES et al, 1993) e na interação com microrganismos (LAMBAIS et al, 2006;MITCHELL et al, 2010).…”

“…The concept of environmental filters can help to understand the forces that maintain biological diversity, both taxonomic and functional, as well as explain abundance and distribution patterns of species in landscapes, which are critical problems in ecological studies (Elith & Leathwick, 2009). They can also explain the regeneration of tree species that live under the canopy, making it possible to relate the maintenance of biodiversity of tree species to the composition and structure of tropical and subtropical forest canopies (Gandolfi, Joly, & Rodrigues, 2007).…”
