A review of post-construction monitoring practices used in the evaluation of tr...

Martins, Ricardo C.; Bernardino, Joana; Moreira, Francisco

Bird mortality by collision is one of the major biodiversity impacts of transmission power lines. The European Union legislation determines that overhead power lines subject to Environmental Impact Assessment (EIA) procedure should be monitored at post-construction to confirm the predicted impacts, and evaluate the effectiveness of the implemented mitigation measures. In light of the frequent calls to improve s...


Long-term management practices successfully reduce bird-related electrical faul...

Moreira, Francisco; Martins, Ricardo C.; Aguilar, Francisco F.; Canhoto, António; Martins, Jorge; Moreira, José; Bernardino, Joana

Bird nests on transmission lines can cause electrical faults which reduce service reliability. To address this problem, since the mid-90s, the Portuguese Transmission System Operator (TSO) has undertaken management actions to discourage white storks Ciconia ciconia from nesting in hazardous locations of the pylons. Here, we compiled and analyzed an 18-year series of data on electrical faults, TSO management act...


Distribution of alien tetrapods in the Iberian Peninsula

Ascensão, Fernando; D'Amico, Marcello; Martins, Ricardo C.; Rebelo, Rui; Barbosa, A. Márcia; Bencatel, Joana; Barrientos, Rafael; Abellán, Pedro

We present a dataset that assembles occurrence records of alien tetrapods (amphibians, reptiles, birds and mammals) in the Iberian Peninsula, a coherent biogeographically unit where introductions of alien species have occurred for millennia. These data have important potential applications for ecological research and management, including the assessment of invasion risks, formulation of preventive and managemen...


Power line routing and configuration as major drivers of collision risk in two ...

Marques, Ana Teresa; Martins, Ricardo C.; Silva, João Paulo; M. Palmeirim, Jorge; Moreira, Francisco

Collision with power lines is a major cause of mortality for many bird species. Understanding the biotic and abiotic factors that increase collision risk is therefore important for implementing mitigation measures to minimize mortality, such as power line rerouting or wire marking. Here, we used collision events registered during 2003–2015 along 280 km of transmission power lines in southern Portugal to analyse...


Distribution of alien tetrapods in the Iberian Peninsula

Ascensão, Fernando; D'Amico, Marcello; Martins, Ricardo C.; Sampaio e rebelo, Rui; Barbosa, A. Márcia; Bencatel, Joana; Barrientos, Rafael

We present a dataset that assembles occurrence records of alien tetrapods (amphibians, reptiles, birds and mammals) in the Iberian Peninsula, a coherent biogeographically unit where introductions of alien species have occurred for millennia.

Response of vertebrate scavengers to power line and road rights-of-way and its ...

Bernardino, Joana; Bispo, Regina; Martins, Ricardo C.; Santos, Sara; Moreira, Francisco

Linear infrastructures, such as power lines and roads, are an important source of bird mortality. However, little is known on the potential effect of these infrastructures on local scavenger guilds, their foraging activity and the resulting bird carcass removal patterns. This is an important source of bias in studies aiming to quantify bird fatalities due to linear infrastructures. We used camera-traps to recor...


Bird collisions with power lines: prioritizing species and areas by estimating ...

D'Amico, Marcello; Martins, Ricardo C.; Álvarez-Martínez, Jose M.; Porto, Miguel; Barrientos, Rafael; Moreira, Francisco

Aim: Power lines can represent an important source of bird mortality through collision. The identification of more susceptible species, in terms of expected populationlevel impacts, requires detailed biological and mortality information that is often difficult to obtain. Here, we propose a species prioritization method based on relatively easily accessed information, aimed to identify both species and areas wit...


EU protected area network did not prevent a country wide population decline in ...

Silva, João P.; Correia, Ricardo; Alonso, Hany; Martins, Ricardo C.; D’Amico, Marcello; Delgado, Ana; Sampaio, Hugo; Godinho, Carlos; Moreira, Francisco

Background. Few studies have assessed the effectiveness of the Protected Area networks on the conservation status of target species. Here, we assess the effectiveness of the Portuguese Natura 2000 (the European Union network of protected areas) in maintaining a species included in the Annex I of the Bird Directive, namely the population of a priority farmland bird, the little bustard Tetrax tetrax. Methods. We ...


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...


Wintering and migrating populations of dunlin calidris alpina using the tagus e...

Martins, Ricardo C.

Waders typically perform long-distance migrations between breeding and wintering areas, depending on a network of stopover sites to refuel along their flyway. Most wetlands act both as wintering and stopover areas for different wader populations and their distinct ecological constrains might lead them to different patterns of resource use, which is important information to plan conservation. The main aim of thi...
