Guião de Boas Práticas: Solução Inovadora para a Redução de Mortalidade de Aves...
Infante, Samuel; Rochinha, Carlos; Silva, Carmo; Oliveira, André; Pedroso, Nuno; Salgueiro; Mira, AntónioEm Portugal, estima-se que dezenas de milhares de aves morram anualmente em linhas de distribuição de eletricidade de média tensão por colisão com os cabos ou eletrocutadas nos apoios. Alguns estudos apontam que este efeito levou ao declínio local de diversas espécies ameaçadas, como a águia-de-Bonelli ou o sisão. Dada a severidade do impacte, tornou-se essencial procurar medidas que minimizem o risco de mortal...
Best practice guide. Innovative solution to reduce bird mortality in medium-vol...
Infante, Samuel; Rochinha, Carlos; Silva, Carmo; Oliveira, André; Pedroso, Nuno; Salgueiro, Pedro; Mira, AntónioEstimates indicate that tens of thousands of birds are killed in Portugal every year by collision with cables or electrocution on the utility poles of medium-voltage power lines. Some studies indicate that this effect led to the local decline of several threatened species, such as the Bonelli’s eagle or the little bustard. The severity of such impact justified the search of solutions to minimize the risk of bir...
MAMMALS IN PORTUGAL: A data set of terrestrial, volant, and marine mammal occur...
Grilo, Clara; Afonso, Beatriz C.; Afonso, Filipe; Alexandre, Marta; Aliácar, Sara; Almeida, Ana; Alonso, Ivan Prego; Álvares, Francisco; Alves, PauloMammals are threatened worldwide, with 26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mam mals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems func tionality and resilience, and theref...

Wired: impacts of increasing power line use by a growing bird population
Moreira, Francisco; Encarnação, Vitor; Rosa, Gonçalo; Gilbert, Nathalie; Infante, Samuel; Costa, Julieta; D'Amico, Marcello; Martins, Ricardo C.Power lines are increasingly widespread across many regions of the planet. Although these linear infrastructures are known for their negative impacts on bird populations, through collision and electrocution, some species take advantage of electricity pylons for nesting. In this case, estimation of the net impact of these infrastructures at the population level requires an assessment of trade-offs between positi...
