The road to success and the fences to be crossed: considering multiple infrastr...

Linear infrastructure represent a barrier to movement for many species, reducing the connectivity of the landscapes in which they reside. Of all linear infrastructure, roads and fences are two of the most ubiquitous, and are understood to reduce landscape connectivity for wildlife. However, what is often neglected consideration is a holistic approach of modelling the effects of multiple types of linear infrastr...

Road encroachment mediates species occupancy, trait filtering and dissimilarity...

Assessing the road effects on biodiversity is challenging because impacts may depend on both wildlife responses to roads and on the spatial arrangement of roads. We questioned whether an increase in road encroachment leads to significant changes in species occurrence and community composition. Using a large citizen-science dataset of point-counts performed throughout Iberian Peninsula, we modelled the effect of...

Mud-puddling on roadsides: a potential ecological trap for butterflies

Road-kill represents a major threat for butterflies and more generally for pollinators. Here we report an observation of conspicuous aggregations of butterflies mud-puddling on roadsides and, for this reason, being massively road-killed by farm vehicles.

Distribution of alien tetrapods in the Iberian Peninsula

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...

Are road-kills representative of wildlife community obtained from atlas data?

Systematic road-kill surveys are useful to study the impact of roads on wildlife. However, they are time-and budget-consuming, so the use of non-systematic data in road ecology is currently gaining popularity (for instance, by environmental consultants). Some data sources such as atlases (i.e., compilations of species records from a given region), which can include non-systematic and citizen-science data, can e...

Inappropriate tourist behavior in protected areas can lead to wildlife road‐kills

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

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...

Beware that the lack of wildlife mortality records can mask a serious impact of...

Linear infrastructures (e.g. roads, railways or power lines) promote a myriad of negative impacts on wildlife around the world, of which direct mortality is the most visible one. When high mortality rates are found, mitigation measures are often discussed and applied. On the other hand, the lack of mortality is commonly interpreted as evidence of low impact on wildlife. We argue that the lack of mortality may a...

Wired: impacts of increasing power line use by a growing bird population

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...
