HiDaFernPT: Historical data of spore availability for 121 fern and lycopod taxa...
Timóteo, Sérgio; Heleno, Ruben; Covelo, Filipe Manuel Ferreira Rodrigues; Santos, Joaquim; Lopes, Pedro; Carmo Gouveia, António; Matos, ArménioSpecies phenology is being altered by ongoing climate changes with yet underappreciated consequences for ecological processes and ecosystem stability. Contrary to what happens with some key life events of flowering plants, comparatively little information exists about fern and lycophyte phenology and how it is affected by the current climatic changes. In part, this stems from the lack of long-term datasets. Her...
O armário: Fruiting phenology data for 4,462 plant taxa in Portugal (1926-2013)
Heleno, Ruben; Costa, Jose M.; Covelo, Filipe Manuel Ferreira Rodrigues; Santos, Joaquim; Lopes, Pedro; Gouveia, António C; Matos, ArménioSpecies phenology - the timing of key life events - is being altered by ongoing climate changes with yet underappreciated consequences for ecosystem stability. While flowering is generally occurring earlier, we know much less about other key processes such as the time of fruit ripening, largely due to the lack of comprehensive long-term datasets. Here we provide information on the exact date and site where seed...
Hakea decurrens invasion increases fire hazard at the landscape scale
Gerber, Dionatan; Azevedo, João; Nereu, Mauro; Oliveira, Aline Silva de; Marchante, Elizabete; Jacobson, Tamiel Khan Baiocchi; Silva, Joaquim S.Hakea decurrens subsp. physocarpa is an invasive fire-adapted shrub of Australian origin that is quickly expanding in Portugal with potential impacts on fire behavior and fire regime. In this study we examined the effects of H. decurrens on fire hazard by assessing fire behavior indicators at the landscape scale, using a modeling and simulation approach. Six fuel models for H. decurrens were developed through f...
Recent land use and land cover pressures on Iberian peatlands
Fernandes, Raquel; Geraldes, Miguel; Marchante, Elizabete; Durán, Jorge; Capinha, CésarIberian peatlands have been severely affected by land use and land cover (LULC) changes. Despite these pressures, some peatlands persist in the region, although their susceptibility to LULC change remains poorly understood. This study presents the most detailed and extensive distribution data for Iberian peatlands to date and analyzes the dynamics and drivers of LULC in Iberian peatlands and their surrounding a...
Managing an invasive tree in coastal dunes: The importance of follow-up treatme...
Duarte, Liliana Neto; Marchante, Elizabete; Marchante, HéliaConservation of biodiversity in protected areas is often threatened by invasive alien plants (IAPs), and its successful management requires proper planning, resources, and monitoring to adjust future interventions. Although follow-up controls and evaluation of different management actions through monitoring programs are crucial in an adaptive management strategy, they are often neglected. Acacia longifolia is o...
Knowledge and perceptions of invasive plant biocontrol in Europe versus the res...
Marchante, Hélia; Marchante, Elizabete; Verbrugge, Laura; Lommen, Suzanne; Shaw, RichardBiological control (BC) of invasive alien plants (IAP) can be an effective environmental management approach. It has only very recently been adopted in Europe and is underutilized compared to other continents where this method has been successfully implemented for over a century. This is in sharp contrast to the BC of invertebrate pests, which has been taken up widely within Europe. It has been suggested that t...
Public perceptions about the invasive pampas grass, Cortaderia selloana: a case...
Roldão Almeida, Mónica; Marchante, Elizabete; Marchante, HéliaCortaderia selloana (pampas grass), native to South America, is a widespread invasive plant in several regions of the World, including the south of the Atlantic Arc (Europe), where it has been used as an ornamental species. Citizens may help to spread it, e.g., planting it in their gardens, but on the other hand, when they are aware of its invasiveness, can contribute to control it and prevent its spread. An on...
Tripartite networks show that keystone species can multitask
Timóteo, Sérgio; Albrecht, Jörg; Rumeu, Beatriz; Norte, Ana C.; Traveset, Anna; Frost, Carol M.; Marchante, Elizabete; López‐Núñez, Francisco A.Keystone species are disproportionately important for ecosystem functioning. While all species engage in multiple interaction types with other species, keystone species importance is often defined based on a single dimension of their Eltonian niche, that is, one type of interaction (e.g. keystone predator). It remains unclear whether the importance of keystone species is unidimensional or if it extends across i...
Tripartite networks show that keystone species can multitask
Timóteo, Sérgio; Albrecht, Jörg; Rumeu, Beatriz; Norte, Ana C.; Traveset, Anna; Frost, Carol M.; Marchante, Elizabete; López-Núñez, Francisco A.1. Keystone species are disproportionately important for ecosystem functioning. While all species engage in multiple interaction types with other species, keystone species importance is often defined based on a single dimension of their Eltonian niche, that is, one type of interaction (e.g. keystone predator). It remains unclear whether the importance of keystone species is unidimensional or if it extends acros...
Establishment, spread and early impacts of the first biocontrol agent against a...
López-Núñez, Francisco Alejandro; Marchante, Elizabete; Heleno, Ruben; Duarte, Liliana Neto; Palhas, Jael; Impson, Fiona; Freitas, HelenaClassical biocontrol is key for the successful management of invasive alien plants; yet, it is still relatively new in Europe. Although post-release monitoring is essential to evaluate the effectiveness of a biocontrol agent, it is often neglected. This study reports the detailed post-release monitoring of the first biocontrol agent intentionally introduced against an invasive plant in continental Europe. The A...
