Public Perception of Invasive Plant Species: Assessing the impact of workshop a...
Reis, Catarina Schreck; Marchante, Hélia; Freitas, H.; Marchante, ElizabeteInvasive species are one of the main threats to biodiversity worldwide. Even though they are identified and recognized as such by the Portuguese law, the majority of the population is not yet aware of this problem. Aiming to increase awareness about biological invasions among young students, a workshop on Invasive Plant Species was organized at the Botanical Museum of the University of Coimbra. A total of 170 t...
Short- and long-term impacts of Acacia longifolia invasion on the belowground p...
Marchante, Elizabete; Kjøller, Annelise; Struwe, Sten; Freitas, HelenaMany coastal dune ecosystems in Portugal are invaded by the leguminous tree Acacia longifolia (Andrews) Willd. This exotic species was first introduced over one hundred years ago in an effort to mitigate dune erosion and loss of coastal landscapes. However, since then A. longifolia has spread to new areas, displacing the native vegetation. These invaded ecosystems contrast with the native dune ecosystems that a...
Soil recovery after removal of the N2-fixing invasive Acacia longifolia : cons...
Marchante, Elizabete; Kjøller, Annelise; Struwe, Sten; Freitas, HelenaAbstract Invasion by Acacia longifolia alters soil characteristics and processes. The present study was conducted to determine if the changes in soil C and N pools and processes induced by A. longifolia persist after its removal, at the São Jacinto Dunes Nature Reserve (Portugal). Some areas had been invaded for a long time (>20 years) and others more recently (<10 years). For each type of invasion, (i.e., lon...
Invasion of Portuguese coastal dunes by Acacia longifolia : impacts on soil eco...
Marchante, Elizabete Maria Duarte CanasInvasion by alien species is considered one of the main threats to the world's biodiversity, causing extensive ecological, economical, and social impacts. In particular, impacts on soil ecology may be relevant, with consequences for ecosystem processes and services. In Continental Portugal, more than 15 % of the vascular flora is exotic, with about 40 % of the alien species considered potentially or actually in...
Recovery Potential of Dune Ecosystems Invaded by an Exotic Acacia Species (Acac...
Marchante, Hélia S.; Marchante, Elizabete M.; Buscardo, Erika; Maia, José; Freitas, HelenaThe effect of mechanical clearing and litter removal on control of Sydney golden wattle was studied in areas of Portugal that had been invaded for either long or short periods. The plant species that emerged and soil parameters were monitored to assess the recovery potential and the soil status of these areas after Sydney golden wattle control. More plant species emerged in the plots where mechanical control in...
