“…and control sites. Both invaded and uninvaded sites had a lower number of woody species than would be expected considering the local woody flora described previously in the study area by Miatto et al (2011). Miatto et al detected 33 woody species in the same invaded sites and 64 in the adjacent uninvaded sites, which in general were also more diverse.…”

“…Consequently, remarkable differences between invaded and uninvaded sites concerned with the established woody vegetation (Miatto et al, 2011) could not be found in the seed bank. The seed morphology of the dominant species in the seed bank of both invaded and uninvaded sites highlights the prevalence of persistent seed banks in high biomass sites dominated by Pteridium.…”

“…For example, in 1962 the total area of Cerrado in São Paulo state, Brazil covered about 33,929 Km 2 (13.7%) (Borgonovi and Chiarini, 1965) but 30 years later in 1992, it was reduced to 2,379 Km 2 (<1%) (Kronka et al, 1998). Given that continuous loss of Cerrado, any expansion of invasive species in its remnants will increase its degradation through continuing loss of biological diversity (Pivello et al, 1999;Miatto et al, 2011). One problematic invasive species of these areas is P.arachnoideum, which although being a native species, can be an aggressive weed species in some areas of Brazilian ecosystems (Pivello et al, 1999;Silva and Silva Matos, 2006).…”

The role of Pteridium arachnoideum(Kaulf) on the seed bank of the endangered Brazilian Cerrado

The native bracken (Pteridium arachnoideum) often occurs in mono-specific stands in the Brazilian Cerrado, and this dominance can impact on both the above-ground vegetation and soil seed bank. This study investigated how invasion by this species over a 20-year period changed the seed bank and the relationship between the seed bank and litter mass. We extracted soil samples from three replicated invaded and uninvaded sites, and followed seedling emergence for six months. We collected the above-ground biomass and litter of P. arachnoideum in ten 1m 2 plots from three invaded sites. There was no difference between invaded and uninvaded areas in seed bank richness, diversity or overall abundance. The most abundant family was the Melastomataceae, followed by the Poaceae. The Melastomataceae was more abundant in uninvaded sites, but the most common species of this family (Tibouchinastenocarpa) was not affected. The grasses were more common in invaded sites in the rainy season and were affected by heterogeneity in the litter layer. The seed bank could play a role in the recovery of these invaded areas, but the presence of weeds and invasive grasses could constrain their use as a management strategy.Keywords: bracken, Melastomataceae, litter, savanna, biological invasion. Impacto de Pteridium arachnoideum (Kaulf) no banco de sementes do CerradoResumo O samambaião (Pteridium arachnoideum) frequentemente domina áreas de cerrado, e pode alterar tanto a vegetação estabelecida quanto o banco de sementes do solo. Nesse estudo investigamos como áreas de cerrado invadidas por essa espécie a mais de 20 anos alteraram o banco de sementes, e também a relação entre banco de sementes e quantidade de serapilheira. Extraímos amostras de solo em três invadidas e em áreas controle adjacentes, e monitoramos a emergência de plântulas por seis meses. Coletamos a biomassa aérea e a serapilheira de P. arachnoideum em dez parcelas de 1m 2 nas áreas invadidas. Ariqueza, diversidade e abundância totalnão diferiram entre áreas invadidas e controle. A família mais abundante foi Melastomataceae, seguida por Poaceae. Melastomataceae foi mais comum em áreas controle, mas não a espécie mais comum nessa família (Tibouchina stenocarpa). Gramíneas foram predominantes em áreas invadidas durante a estação chuvosa, e foram afetadas pela heterogeneidade da camada de serapilheira. O banco de sementes pode ser importante para a recuperação dessas áreas invadidas, mas esse uso pode ser prejudicado pela presença de ervas daninhas e gramíneas invasoras.Palavras-chave: samambaião, Melastomataceae, serapilheira, savana, invasão biológica.

“…Over much of its range it is a serious weed problem. Although a great deal is known about Pteridium ecology, its form and function, and control measures, most of this has been derived from studies in Europe about Pteridium aquilinum (L.) Kuhn (Marrs and Watt, 2006), and until recently there has been much less data from South America (Alonso-Amelot and Rodulfo-Baechler, 1996; Thomson and Alonso-Amelot, 2002;Hartig and Beck, 2003;Alonso-Amelot and OliverosBastidas, 2005;Silva and Silva Matos, 2006;Silva Matos and Belinato, 2010;Miatto et al, 2011). This lack of data from South America is surprising because Pteridium esculentum arachnoideum abundance is causing concern for animal health across the continent (França et al, 2002;Marçal et al, 2002;Marçal, 2003).…”

A comparative study of resource allocation in Pteridium in different Brazilian ecosystems and its relationship with European studies

Pteridium is a cosmopolitan genus that acts as an invasive species in many parts of the world. Most research on this genus has occurred in Europe, and there is a lack of data on it from South America, in spite of causing considerable conservation problems. We compared the biomass allocation of P. esculentum subsp. arachnoideum in two ecosystems in Brazil -Atlantic forest and Brazilian savanna. We measured the biomass of fronds, rhizomes and above-ground litter. We also compared the density, length and biomass of fronds from this Brazilian study with similar data of P. esculentum subsp. arachnoideum derived from Venezuela and P. aquilinum from Europe. P. esculentum subsp. arachnoideum showed a wide response range. We found a negative relationship between frond and necromass , indicating a negative feedback effect, while a positive relationship was observed between frond and rhizome biomass. The continental comparison of relationships showed that Pteridium responds in a different way in both Brazil and Europe, and that in Brazil fronds tend to be longer and heavier, presumably as a result of the continuous growing season in South America while is shortened in Europe by frost. The paper shows the ability of Pteridium to adapt to different ecosystems.Keywords: bracken, resource partitioning, Atlantic Forest, Cerrado, biomass. Estudo comparativo da alocação de recurso em Pteridium em diferentes ecossistemas brasileiros e sua relação com estudos na europa ResumoPteridium é um gênero cosmopolita que inclui espécies invasoras em várias partes do mundo. Os estudos sobre o gênero têm ocorrido principalmente na Europa, e existem poucas informações para as espécies que ocorrem na América do Sul. Nesse estudo comparamos a alocação de biomassa de P. esculentum subsp. arachnoideum em dois ecossistemas brasileiros -Mata Atlântica e Cerrado -em cada um dos quais medimos a biomassa nos rametas, nos rizomas e na serapilheira. Comparamos, também, a densidade, comprimento e biomassa dos rametas com informações obtidas sobre P. esculentum subsp. arachnoideum na Venezuela e P. aquilinum na Europa. P. esculentum subsp. arachnoideum apresentou respostas distintas. Encontramos uma relação negativa entre a biomassa de rametas e da serapilheira, indicando uma retro-alimentação negativa, enquanto houve uma relação positiva entre a biomassa dos rametas e dos rizomas. A comparação das relações entre os continentes indicou que Pteridium responde diferentemente no Brazil e na Europa, e também que no Brasil os rametas são maiores e contêm mais biomassa, possivelmente devido à estação de crescimento contínua, enquanto na Europa o crescimento é limitado pelas baixas temperaturas. Esse estudo demonstra o sucesso adaptativo de Pteridium em diferentes ecossistemas.Palavras-chave: samambaião, alocação de recursos, Mata Atlântica, Cerrado, biomassa.

“…Registros de invasão: Apesar de considerada cosmopolita, o gênero é reportado como invasor na região do Andes, no sudeste do Equador (Beck et al, 2008), na Inglaterra e no México (Colleen, 2011). No Brasil existem estudos descrevendo o gênero como invasor na Floresta Estacional Semidecidual (Silva, Matos & Belinato, 2010;Portela et al, 2009;Silva & Matos, 2006) e no Cerrado (Matos, Xavier, Tiberio, & Marrs, 2014;Miatto, Silva, Matos, & Marrs, 2011;Pinheiro & Durigan, 2009 Origem: Nativa do Himalaia e Sul da China.…”
