| In bromeliad populations, amount of light and available substrates influence individuals spatial organization. In Atlantic Rainforest of Ilha Grande, the heliophylous bromeliad Neoregelia johannis is a large and abundant species. In this forest, it would be expected that N. johannis would occupy stable substrates, as large trunks, large branches, rock boulders or ground, with high sunlight, enough for the bromeliad survivor. In the present work, we analyzed the distribution and most used substrates of N. johannis in secondary forest. We analyzed the frequency of reproductive modes (sexual and vegetative) used by the bromeliad shoots, registering if the shoots were originated from seeds or by vegetative reproduction. The results indicated an aggregated... |

| Piperaceae species of forest remnants of Maringá, Paraná, Brazil present vegetative propagation through root or stem (stolon). This reproduction type was verified in Piper amalago L., P. arboreum Aublet, P. xylosteoides (Kunth) Steud., Peperomia parnassifolia Miq. and Ottonia martiana Miq. Root and stem branches of these species were analyzed anatomically. Results indicated that the vegetative propagation in Piperaceae should be studied in other forests. New and additional studies should be made if the structural variations were induced environmentally or fixed genetically. |
