“…Cabe destacar que apesar dos impactos da invasão de palmeiras exóticas ainda serem pontuais, devido ao diversificado uso econômico destes vegetais, como produção de óleo, de palmito, frutos, etc., esta situação poderá se tornar mais comum no futuro, inclusive no interior e nas Zonas de Amortecimento de Unidades de Conservação (Tibério et al, 2016). O Plano de manejo do PEAL estabelece como prioridade a pesquisa das espécies exó-ticas invasoras e ações de restauração que permitam que a vegetação do parque se assemelhe com o passar do tempo à vegetação do contíguo Parque Estadual da Cantareira.…”

ResumoA invasão biológica é um processo frequente em ambientes naturais do mundo inteiro. Em locais invadidos, é necessária a avaliação da interferência da espécie invasora no ecossistema, antes que medidas de manejo sejam adotadas. Trechos do Parque Estadual Alberto Löfgren (PEAL), São Paulo, sudeste do Brasil, se encontram em diferentes graus de colonização por três espécies de palmeiras exóticas invasoras (PEIs). O presente estudo visou verificar como a densidade dessas PEIs influencia no uso dos habitats pelas aves de sub-bosque. Foram estabelecidas duas áreas amostrais com diferentes densidades de PEIs. Os métodos de trajetos e capturas com rede de neblina foram utilizados em conjunto para o levantamento dos dados sobre a avifauna, e o método de ponto quadrante, aliado à contagem dos indivíduos de PEIs, caracterizou a estrutura da vegetação nessas áreas amostrais. A densidade de PEIs diferiu significativamente entre as áreas. Em relação às aves, ocorreu diminuição significativa no total de contatos obtidos na área com maior densidade de PEIs. Os resultados sugerem que o aumento da densidade de PEIs interfere no uso dos habitats pelas aves, sendo necessário realizar controle das populações dessas palmeiras, para evitar perdas de espécies de aves nas assembleias locais. Palavras-chave:Arecaceae, conservação, invasões biológicas. AbstractBiological invasion is a common process in natural environments around the world. In an invaded habitat, the interference of the invasive species in the ecosystem must be evaluated. The Alberto Löfgren State Park (PEAL) in São Paulo, southeastern Brazil, is suffering colonization from three species of invasive exotic palms (IEPs). The present study intended to verify how IEP density influences understory bird assemblages in this park. We have established two sampling areas with different palm density. Both line transects and mist nets were jointly used to survey the avifauna. Point-centered quarter sampling, allied with the counting of individual IEP, characterized the vegetation structure. IEP density differed significantly among sampling areas. We encountered a negative relation between IEP density and bird contacts. The results suggest that the increase in IEPs density interfere with the habitat use by birds. The control of palm populations is required, in order to avoid losses of birds in the future.

“…E. oleracea is a new and an exotic palm species of Indonesia. Ecological processes in native populations, like pollination and dispersal patterns, may change as a result of the introduction of a species, changing the population structure [19]. Even though palm species are not frequently regarded as invasive [19], the overall detrimental effects of exotic species on ecosystems and biodiversity have long been understood.…”

When it has same genus (congeneric) with local species, the exotic plant species may encourage competition for pollinators or result in interspecific interference with pollen in native flowers, among other effects on the local community's ecological processes [19].…”

Euterpe oleracea (Arecaceae), which is known as Acai, is a palm tree originating from swampy forest of Suriname. Acai is naturally distributed in swampy, sandy soil, river edges and seasonally flooded habitats; hence it is considered as paludiculture species. Acai’s domestication study in Indonesia is limited, therefore our study aimed to assess morphology and germination of Acai’s seeds in the nursery, and early growth performance in the field. Acai’s seed diameter was ranging from 0.88±0.01 cm; seed wet weight was 1.19±0.31 g. Acai seeds germinated for up to 5-7 months. Soaked seeds in warm water overnight had 8.33% germination rate, while soaked seeds in tap water overnight had lesser germination rates (1.75%). After one year transplanted to a peat swamp forest ecosystem of Tumbang Nusa, Central Kalimantan, Acai’s seedlings had 100% survival rate. The relative growth rate of height and diameter of Acai seedlings were 4.21 cm month−1 and 0.08 cm month−1, respectively. Acai seedlings survived floodings that occurred in November 2021 to March 2022. The water level was around -35.6 to 17.7 cm. Despite of some challenging, açai is a promising species to be domesticated on degraded peatlands.
