Ecological restoration has the potential to accelerate the recovery of biodiversity and ecosystem services in degraded ecosystems. However, current research queries whether active restoration is necessary. We evaluated plant-pollinator networks during spring at replicated sites within an actively restored quarry, at abandoned quarries undergoing sp...
Roads can block animal movement and reduce persistence of species living in road surroundings. Movement restrictions on local populations may even increase extinction risk of abundant small mammals. However, road verges (road managed area between
the edge of the road and the beginning of private land) may provide refuge and corridors for small mamm...
Quarrying activities cause profound modifications on ecosystems, such as removal of vegetation cover, biodiversity loss and depletion of ecosystem services. Ecological restoration stands as a solution to revert such effects. Concomitantly, awareness is currently being given on ecosystem services and ecological processes to evaluate restoration effi...
Recent studies have highlighted the positive effects of road verges on the
abundance of small mammals. However, most of these studies occurred in intensively grazed or cultivated areas, where verges were the last remnants of suitable
habitats, which could mask the true effects of roads on population traits. We analysed the effects of roads on small...
Roads disrupt landscape connectivity for many species. These infrastructures can be barriers to movement and, in the long-term, threaten the persistence of several mammal populations living on roadsides. It is widely recognized that small mammals use road verges as habitat and corridor when roads cross intensively managed landscapes. Nevertheless,...
Local species assemblages are likely the result of habitat and landscape filtering. However, there is still limited knowledge on how landscape functional connectivity complements habitat attributes in mediating local species assemblages in real-world fragmented landscapes. In this study, we set up a non-manipulative experimental design in a standar...
Highly degraded habitats such as quarries often require active restoration efforts, but classical reclamation practices may undermine the occurrence of species that are locally rare or of conservation concern. We argue that some species can benefit from quarry landform whenever the presence of certain elements in the surroundings are preserved. We...
Quarry exploitation and restoration practices are expected to have overarching and contrasting impacts on animal communities. Although many studies describe these impacts, they generally overlook the effects on population dynamics and individual movements. We assessed the impacts of quarry exploitation and restoration activity on population dynamic...
As practitioners promote passive restoration as a complementary approach to technical reclamation, it is imperative to know its drivers. Although the consequences of endozoochory can be crucial to passive restoration success, few experimental studies assess the use of heavily disturbed sites by seed dispersers such as carnivores and how the seeds t...

Abstract:
As practitioners promote passive restoration as a complementary approach to technical reclamation, it is imperative to know its drivers. Although the consequences of endozoochory can be crucial to passive restoration success, few experimental studies assess the use of heavily disturbed sites by see...
Road mortality is the most noticeable effect of roads on wildlife. Road verges may provide important refuges for small mammals and rabbits, particularly when roads cross intensive agricultural or grazed areas. In these circumstances , the increasing use of verges by prey species may attract predators to road surroundings increasing the risk of road...
Extractive activities are considered one of the most harmful industries, being responsible for losses of more than 80% of biodiversity. At the dawn of the Decade on Ecosystem Restoration declared by the United Nations for 2021-2030, habitat restoration rises as an unparalleled opportunity to achieve Sustainable Development Goals standards.
The SEC...
ContextWhen modeling a species’ distribution, landscapes can alternatively be conceptualized following patch- or gradient-based approaches. However, choosing the most suitable conceptualization is difficult and methods for empirical validation are still lacking. Objectives
To address the conditions under which a given conceptual model is more suita...
Quarries are often considered as ecologically degraded sites with negative impacts on biodiversity as a consequence of extraction operations. The increasing awareness of the importance of the ecosystem services provided by biodiversity led to the execution of several Quarry Rehabilitation Plans (QRP) and Biodiversity Management Plans (BMP) in such...

However, most of these studies occurred in intensively grazed or cultivated areas, where verges were the last remnants of suitable habitats, which could mask the true effects of roads on population traits.

Quarries are accounted as ecologically degraded sites as consequence of industrial mineral extraction. However, quarry landform can provide suitable artificial conditions for rocky species. This study aims to evaluate if the existence of quarries is potentiating Black redstarts (Phoenicurus ochruros) occurrence. Our results intend to explore other...
Evidence that roads have mainly positive or neutral effects on small mammals has been gathered recently despite the fact that these species are one of the most road killed mammal groups. Most of the previously positive documented effects of roads were mainly due to abundance evaluations in habitats under high grazing or agricultural pressure what m...
Turkish gecko (Hemidactylus turcicus) is native to countries surrounding the Mediterranean Sea and is very frequently associated to humanized habitats (Arnold & Ovenden, 2002). They live in warm, dry areas and often thrive in anthropogenic landscape including rock piles, stone walls, cliffs, ruins and around or inside houses (Mateus & Jacinto, 2008...
The increasing road networks threaten ecosystems by direct effects such as increased mortality due to collision
with vehicles and by various indirect effects leading to road avoidance. We censused Tawny Owls Strix aluco and Little Owls Athene noctua in 2005, 2007 and 2009 in a rural landscape in Southern Portugal in order to study the effects of ro...
