Article
Full-text available
The establishment of an introduced species is an important step of the invasion pathway. Often species become established because of their superior competitiveness over the native community or by occupying empty niches. Recently, the red-billed leiothrix Leiothrix lutea has become established in some European natural-woods, which can be quite relev...
Article
Behavioural dominance and aggressiveness may be crucial traits facilitating the establishment of invasive species. Few studies considered agonistic interactions between exotic and native bird species in feeding contexts, particularly when the exotic has social habits. We aimed to know if individuals of a social invasive species, the red-billed leio...

The red-billed leiothrix (Leiothrix lutea) is an Asian-native passerine which has been introduced across several regions of the world, including Europe. Although it is widely considered to be among the most harmful bird invaders, its occurrence in Europe is still understudied. Here, we aim to assess its distribution and population status in Europe....
Article
Interspecific competition is rarely assessed between exotic and distantly related native species, although these can compete for some ecological resources. Here, we assessed the occurrence of interspecific aggression resulting from direct competition between two European native songbird species (henceforth focal species), the robin Erithacus rubecu...
Article
Invasive non‐native species (INNS) are one of the major threats to global biodiversity. Climate change and garden bird‐feeding may facilitate the establishment of INNS. The Red‐billed Leiothrix Leiothrix lutea is a small woodland passerine, native to subtropical Asia, that is an INNS in several parts of the world, including Europe, following escape...
Article
Native birds play a critical role in seed dispersal. The introduction of a new species may result in unpredictable effects on an ecosystem, namely in terms of seed dispersal. The Red-billed Leiothrix Leiothrix lutea is a frugivorous species native to Asia, whose potential role as seed disperser has not yet been analysed in its introduced range in E...

Mammals are threatened worldwide, with ca. 26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated to habitat loss or degradation, and human persecution for terrestrial mammals, and pollution, open net fishing, climate change and prey depletion for marine mammals. Mammals play a key role in...
Article
Quarrying activities cause profound modifications on ecosystems, such as removal of vegetation cover, biodiversity loss and depletion of ecosystem services. Ecological restoration stands as a solution to revert such effects. Concomitantly, awareness is currently being given on ecosystem services and ecological processes to evaluate restoration effi...

The Tagus Estuary hosts a high concentration of juvenile Common Barn Owls (Tyto alba) during the post-fledging dispersal period with more than 15 owls/km detected along roads in the south floodplain of Vila Franca de Xira (SF). The Tyto Tagus project examined the origin of these birds with six re-sightings of 136 colour-ringed nestlings (2006–2008...
Article
Birds can behave aggressively towards conspecifics to defend a territory and to compete for access to food and mates. The effects of phenotypes, such as sex and age, in aggressive behaviour have not yet been fully understood. Moreover, differences in aggression levels can reflect alternative behavioural strategies (i.e. proactive–reactive axis). We...

Article
The decline of oak (Quercus spp.) forests is a current trend in Northern Hemisphere and is characterized by a loss in tree vigour and increased mortality. The canopy insects are suspected to have role in this decline, but there is poor knowledge about their incidence in evergreen-oak stands. The main aim of this study is to characterize the inciden...

Extractive activities are considered one of the most harmful industries, being responsible for losses of more than 80% of biodiversity. At the dawn of the Decade on Ecosystem Restoration declared by the United Nations for 2021-2030, habitat restoration rises as an unparalleled opportunity to achieve Sustainable Development Goals standards. The SEC...
Article
The consequences of species extinctions in ecological communities may be buffered through the rearrangement (rewiring) of the interactions between the remaining species. The structural and functional consequences of such extinctions can be explored by means of computer simulations that try to predict secondary extinctions and the degradation of eco...

Full-text available
In general, interspecific competition has been studied mainly in between species belonging to the same genus or family, since they tend to have more ecological similarities and thus more overlapping niches than more distant relatives. With this work, we aimed to evaluate the occurrence of interspecific competition between two species of passerine b...

Presentation
Full-text available
Interspecific competition in birds has been studied mainly in a breeding context (e.g. singing interactions or nesting-site competition), and less often have researchers analysed aggressive behaviour related with interspecific feeding competition. We evaluated interspecific competition in an owner-intruder context during foraging activity and asses...

Montados form a heterogeneous land-scape of wooded matrix dominated by cork and/or holm oak with open areas characterized by fuzzy boundaries. Montado supports a high biological diversity associated to low intensity management and a landscape diversity provided by a continuous gradient of land cover. Among other features this permits the classifica...

The geographic distribution of some bird species which are potential direct competitors may sometimes overlap extensively, indicating the existence of ecological and behavioural mechanisms to reduce competition. A possible example such a pair is the Robin Erithacus rubecula (Turdidae) and the Blackcap Sylvia atricapilla (Sylviidae), which are abund...

The importance of rice fields for bird conservation has been subject of several studies, mainly focused in core areas as habitat for waterbirds. However, significant parts of the rice field structure, like the irrigation channels that control the water level, are often neglected. These corridor-like areas are frequently characterized by the presenc...

In this note we describe the first documented breeding record of Black-necked Grebe Podiceps nigricollis in Portugal. One pair bred during the spring of 2007 at the Poço da Rua reservoir (Montemor-o-Novo), Alentejo. Two chicks fledged successfully from the three eggs that were laid. Breeding in Portugal might be linked with the decrease in the wate...

IBISurvey: Introduced Bird Interaction Survey is a Citizen Science project from the University of Évora (PT). Its main objective is to assess the environmental, societal and economic impacts of introduced birds in European countries. We encourage observers to report interactions between introduced birds and other animals, plants and humans. Your involvement is essential for helping us to identify which introduced bird species are becoming invasive and to improve our assessment of their environmental, societal and economic impacts. www.labor.uevora.pt/en/ibisurvey/

The red-billed leiothrix (Leiothrix lutea) is an Asian-native passerine bird introduced in several European countries. This species has shown a high invasion success in other regions of the world, namely in the Hawaii, Japan and Reunion Island. Nevertheless, there is an immense lack of knowledge about their occurrence in Europe. Considering this, we aim to use the red-billed leiothrix as model species in biological invasions with focus on the mechanisms promoting their establishment in Europe.
