“…In Restinga da Marambaia, which is located in the municipality of Rio de Janeiro, the terrestrial bromeliads dominate the dense herbaceous layer on the floor of a forest dune. The aboveground biomass of such bromeliads involves a high concentration of nutrients (Souza et al, 2016) which improves soil fertility in the area by leaf litter (Pereira et al, 2005).…”

Restingas are extremely degraded, tropical sandy ecosystems and are poorly studied in terms of nutrient cycling. The present study aimed to evaluate litter dynamics in a forest dune at Restinga da Marambaia, RJ. Litterfall was collected monthly using two parallel transects installed 200 m apart from each other with 15 litter traps (0.25 m 2), over two consecutive years. The litterfall was sorted into leaves, twigs, flowers, fruits, and refuse. Litter decomposition was evaluated by the ratio between litterfall and litter layer on the soil surface, which was estimated every four months by quadrats (0.25 m 2) placed next to the litter traps. The average annual litterfall was low (6.8 t ha-1 year-1), mostly constituted by leaves (70%), with the greatest deposits occurring during the rainy season. The decomposition rate was low (0.85) and the turnover time was long (439 days). This litter dynamic contributes to the nutrient economy.

“…As bromélias epífitas também interferem na ciclagem de nutrientes da floresta, que pela deposição de folhas nos estratos da serrapilheira contribuem para a liberação de nutrientes que podem ser incorporados ao solo. Trabalho realizado por Souza et al (2016) estudando as espécies de bromélias Billbergia amoena, Neoregelia cruenta, Quesnelia quesneliana em florestas de restinga no Rio de Janeiro verificou presença significativa de grandes quantidades de folhas verdes das bromélias na serrapilheira, que armazenam nutrientes em concentrações decrescentes de K > N > P, sendo a Quesnelia quesneliana a bromélia com maiores concentrações.…”

RESUMO A restauração florestal é a ciência, prática e arte de assistir e manejar à recuperação da integridade ecológica dos ecossistemas, incluindo um nível mínimo de biodiversidade e de variabilidade na estrutura e funcionamento dos processos ecológicos e, dentre outras técnicas tem-se o enriquecimento que consiste na introdução de espécies para aumento da diversidade. O presente trabalho buscou introduzir e monitorar a espécie Aechmea bromelifolia (Rudge) Baker em área restaurada no Cerrado. Foram reavaliados 18 indivíduos, em três forófitos diferentes (Jacaranda cuspidifolia Mart., Anadenanthera falcata (Benth.) Speg., Sapindus saponaria L.) e introduzidas e avaliadas mais dez indivíduos em dois forófitos distintos (Dipteryx alata Vogel e Caryocar brasiliense Cambess), quantificando-se a produção de folhas e a intensidade de luz incidente no local. Os indivíduos avaliados tiveram bom desenvolvimento na maioria dos forófitos, sendo Jacaranda cuspidifolia Mart. que promoveu o melhor desenvolvimento. A taxa de mortalidade nos indivíduos introduzidos foi nula demonstrando que a espécie estudada apresenta alta adaptabilidade. Não foi encontrada correlação entre a intensidade luminosa e a produção de folhas, demonstrando que o sombreamento pode não ter sido prejudicial. Foi possível a observação de processos ecológicos como a polinização, abrigo para fauna e a ciclagem de nutrientes. Desta forma o enriquecimento com bromélias se mostra eficiente para áreas restauradas e pode colaborar minimamente com os processos ecológicos locais.

“…Restinga is a coastal ecosystem of the Atlantic Forest biome, with high salinity and temperature, intense sun exposure, and sandy soils with low water retention (VALDEMARIN et al, 2019). The biodiversity in Restinga areas consists mainly of Bromeliaceae species, important as habitat for fauna (SOUZA et al, 2016). The genus Quesnelia (Bromeliaceae) has 21 endemic species in the Atlantic Forest distributed in the coast from the Rio de Janeiro to Bahia states (MANTOVANI et al, 2012), such as Quesnelia quesneliana (Brongniart) L.B.…”

Bromeliad Quesnelia quesneliana (Brongniart) L.B. Smith has been reported in the Atlantic Forest, Rainforest, Mesophilic Semideciduous Seasonal Forest, Mangroves and Restingas in the Brazilian southeastern states of Rio de Janeiro and Espírito Santo, but information about their fruit and seed morphology, and germination is limited. The aim of this study was to characterize the external morphology of fruit and seeds, germination rate and post-seminal stages of Q. quesneliana. Fruits were collected from Restinga area in the Armação dos Búzios city, Rio de Janeiro, Brazil. The width and length of fruit and seeds (external morphology) were measured, the post-seminal development of the seeds was analyzed and botanical illustrations were made. The indexes t50, uniformity of germination, mean germination time and germination speed coefficient were also calculated. Germination was assessed for 20 days by counting individuals to obtain the post-seminal stages. Ripe Q. quesneliana fruits are pyriform, reddish-brown in color, with light spots, 26 mm long and 10 mm wide, with an average of 148 seeds per fruit and wrapped in a transparent mucilage. The seeds are 2 mm long and 1 mm wide, with epigeal germination, and its seedlings are cryptocotyledonary. The seeds of this species germinate quickly and have no dormancy.
