West Nile (WNV) is a zoonotic arbovirus with an expanding geographical range and epidemic activity in Europe. Not having yet experienced a human-associated epidemic, Portugal remains an outlier in the Mediterranean basin. In this study, we apply ecological niche modelling informed by WNV historical evidence and a multitude of environmental variables from across Portugal. We identify that ecological backgrounds ...
Urban ecosystems are suitable for the introduction and spread of alien bird species, and early detection of their establishment and expansion is crucial to reduce potential negative impacts. In this context, the use of opportunistic citizen science data can have considerable advantages in relation to conventional scientific approaches. We gathered records of parakeets and parrots (Psittaciformes) and mynas and ...
A Lista Vermelha das Aves de Portugal Continental 2022 visa reavaliar o risco de extinção das populações de aves que utilizam de forma regular este território português e identificar as populações ameaçadas, atualizando a secção correspondente que integra o anterior Livro Vermelho dos Vertebrados de Portugal, que data de 2005 (Cabral et al. 2005). Decorridas quase duas décadas desde a última avaliação e tendo e...
West Nile (WNV) is a zoonotic arbovirus with an expanding geographical range and epidemic activity in Europe. Not having yet experienced a human-associated epidemic, Portugal remains an outlier in the Mediterranean basin. In this study, we apply ecological niche modelling informed by WNV historical evidence (1969-2022) and a multitude of environmental variables from across Portugal. We identify that ecological ...
Climate change has been associated with both latitudinal and elevational shifts in species’ ranges. The extent, however, to which climate change has driven recent range shifts alongside other putative drivers remains uncertain. Here, we use the changing distributions of 378 European breeding bird species over 30 years to explore the putative drivers of recent range dynamics, considering the effects of climate, ...
Grassland birds are among the most threatened and fastest declining terrestrial vertebrate species in Europe, principally due to agricultural intensification and transformation. The little bustard is a priority grassland bird under the European Directive (2009/147/CE) that led to the classification of a network of Special Protected Areas (SPAs) in Portugal. A third national survey carried out in 2022 reveals a ...
Significance We used a unique long-term dataset on breeding bird counts covering an entire continent to quantify the influence of ecological barriers on climate change–driven bird community shifts. We show that ecological barriers exert a significant effect on the distance and direction of bird community composition shifts at the continental scale, with coastlines and elevation having the strongest influence. T...
Os atlas são considerados como ferramentas fundamentais para a gestão e conservação das populações de aves selvagens. O seu conceito e aplicação tem sido implementado em vários grupos animais, e também nas plantas, constituindo atualmente peças essenciais para um melhor conhecimento da distribuição da biodiversidade. É certo que, desde o momento em que a Ornitologia se desenvolveu enquanto ciência, o conhecimen...
Las aguas portuguesas son un corredor migratorio vital para las aves marinas europeas. Los conteos desde la costa pueden monitorizar poblaciones globales y locales de aves marinas, así como estudiar sus tendencias a largo plazo. Hemos empleado el TRIM (Tendencias e Índices para Monitorear Datos) y los Modelos General Aditivos (GAM) en diez años de un conjunto de datos de ciencia ciudadana de conteos de aves mar...
