Article
Full-text available
Road mortality is an increasing problem for terrestrial vertebrate conservation due to the increase of both road numbers and vehicle Xow. We hypothesize that the proba-bility of a predator being killed on the road is related to the presence of its prey adjacent to the road, which is likely to be related to the use that these predators make of road...

Transportation infrastructure are one of the main threats for the conservation of many vertebrate species. Although many animals die every day on roads, mammal carnivores are one of the most susceptible groups due to their low reproductive rates, large home ranges, and high mobilities, also most of them are threatened. A better understanding of how...
Article
Differences between air and ground temperatures are expected to narrow with the advance of the season in temperate regions (aka seasonal restriction in the availability of thermal microhabitats), which may activate behavioral and physiological responses of ectotherm species adapted to temperate climates. However, according to cost-benefit models of...
Conference Paper
Anticoagulant rodenticides can help to reduce rodent overpopulations in agricultural areas, but they also produce harmful effects on natural predators when ingested directly or by consuming poisoned preys. We aimed to study the presence of rodenticides in the European polecat (Mustela putorius), a renowned rodent consumer. Forty livers of roadkille...

Full-text available
Ontogeny is expected to be a determinant factor affecting production of colour patches in lizards, while immune challenges or sudden weight loss may impair the maintenance of pigment-based coloration within a breeding season. We translocated males of the lizard Psammodromus algirus between two sampling plots that differed in distance to a road, veg...
Article
Full-text available
Approximately 65% of primate species are facing extinction, with threats including the impacts of linear infrastructures such as roads, railways, and power lines, associated with habitat loss and fragmentation, direct and indirect mortality, and changes in animal behavioral patterns. Nevertheless, this is an often-overlooked topic in primatology, a...

Bien por la curiosidad innata de cualquier naturalista o por un afán de coleccionismo, cuando nos apropiamos de restos biológicos de animales salvajes, como plumas, cráneos y otros, no sólo podemos incurrir en una ilegalidad. Estas acciones llegan a obstaculizar proyectos o estudios de finalidad conservacionista e incluso alterar pruebas en delitos...
Conference Paper
Las carreteras son una de las principales amenazas para la conservación de muchas especies de vertebrados. Los carnívoros son uno de los grupos más susceptibles al impacto de estas infraestructuras por sus altas tasas de mortalidad por atropello. Se realizó un estudio para conocer las variables de mayor influencia en los atropellos de turón europeo...
Conference Paper

Article
Full-text available
The global road network is rapidly growing associated with human economic development. This growthalso entails a high toll for biodiversity, with several well-documented negative impacts on differentspecies. However, there is still a great lack of knowledge about the effects of roads on the persistenceof wildlife populations. Here, we aimed to summ...
Article
Several studies of lizards have made an erroneous interpretation of negative relationships between spectral brightness and parasite load, and thus provided misleading support for the Hamilton–Zuk hypothesis (HZH). The HZH predicts that infected hosts will produce poorer sexual ornamentation than uninfected individuals as a result of energetic trade...
Article
Full-text available
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),...
Article
Full-text available
Mitigation-driven translocations represent an increasingly common management solution to reduce animal mortality and habitat loss caused by human development. Although they currently outnumber other translocation types, there is a lack of scientific approaches to evaluate the outcome of this management tool. We designed an experimental translocatio...
Article
Full-text available
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 asses...

Aim Roads impact wildlife in different ways, among which road mortality has been the most studied. Budgets in conservation biology are usually small, and macroecological approaches have been employed in recent years as the first steps towards guiding management. Carnivores are particularly vulnerable to mortality on roads due to their elevated ecol...
Article
Full-text available
Birds are hosts for several zoonotic pathogens. Because of their high mobility, especially of long‐distance migrants, birds can disperse these pathogens, affecting their distribution and phylogeography. We focused on Borrelia burgdorferi sensu lato, which includes the causative agents of Lyme borreliosis, as an example for tick‐borne pathogens, to...

Full-text available
Aim Power lines can represent an important source of bird mortality through collision. The identification of more susceptible species, in terms of expected population‐level impacts, requires detailed biological and mortality information that is often difficult to obtain. Here, we propose a species prioritization method based on relatively easily ac...
Article
Full-text available
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 l...

Article
Full-text available
One of the main tasks when dealing with the impacts of infrastructures on wildlife is to identify hotspots of high mortality so one can devise and implement mitigation measures. A common strategy to identify hotspots is to divide an infrastructure into several segments and determine when the number of collisions in a segment is above a given thresh...
Article
Transmission and distribution electricity grids are expanding rapidly worldwide, with significant negative impacts on biodiversity and, in particular, on birds. We performed a systematic review of the literature available on bird collisions with power lines to: (i) assess overall trends in scientific research in recent decades; (ii) review the exis...
Article
Infrastructures in natural areas are expanding rapidly worldwide. Consequently, roads, power-lines, and wind-farms cause millions of fatalities across several animal groups. Assessing the population impact of these infra-structures requires sound estimates of the total number of fatalities. These estimates can be heavily biased due to differences i...

Railways play a major role in the global transportation system. Furthermore, railways are presently being promoted by several governments thanks to their economic and environmental advantages relative to other means of transportation. Although railways have clear advantages, they are not free of environmental problems. The objective of this book is...
Chapter
Full-text available
As societies realise the importance of maintaining biodiversity and, accordingly, acknowledge the need for monitoring, minimizing and compensating the impacts of socioeconomic activities, including transportation, more scientists will be called to address these societal challenges. Railway Ecology is emerging in this context as a relatively new fie...
Chapter
Full-text available
In this chapter we provide practical suggestions, together with examples, to identify, monitor and mitigate railway barrier effects on wildlife, as this is considered one of the railways’ greatest impacts. Railways can be both physical and behavioral barriers to wildlife movement, as well as disturbance to populations living close to them. Also, mo...
Presentation
Full-text available
Road ecology is an emerging discipline. Most published studies are still descriptive approximations focusing on road-kills, but also on barrier effect and mitigation measures. In this communication we overview our studies on these topics, aimed to highlight the need for more comprehensive research, focusing on quantifying the impacts of road-kills...
Article
One of the responses of arid-land birds to ongoing climate warming is to shift their ranges towards higher altitudes to track species climatic optima. As this can influence their life history traits, more information is needed on breeding output from these border populations. We studied the breeding biology of the Trumpeter finch (Bucanetes githagi...
Article
Because extended incubation recesses, where incubating songbirds are away from nests for periods much longer than usual, occur infrequently, they have been treated as outliers in most previous studies and thus overlooked. However, egg temperatures can potentially fall below the physiological zero temperature during extended recesses, potentially af...
Article
Full-text available
The incubation stage in avian reproduction could be as costly as the nestling rearing stage. This is particularly true in the case of uniparental incubation, during which both current and future breeding attempts may be compromised. Therefore, the knowledge of the proximate effects that condition the incubation behaviour in free-living bird populat...
Article
Full-text available
The use of nest- boxes to study bird breeding biology, as well their use as a management tool, is widespread. The exact placement of nest-boxes may affect individual preference for these breeding sites; however the influence of determinant factors (e. g., nest- box density) in occupation rates or breeding parameters has not been sufficiently covere...
Article
Full-text available
Breeding mistiming is increasingly frequent in several ecosystems in the face of current climate change. Species belonging to higher trophic levels must employ mechanisms to reduce it. One of these mechanisms is hatching asynchrony, with the eggs in a clutch hatching over a period of several days. Some authors have suggested it to be adaptive when...
