Mapping high-risk areas for Mycobacterium tuberculosis complex bacteria transmi...
Ferreira, Eduardo M; Cunha, Monica; Duarte, Elsa Leclerc; Mira, António; Pinto, Daniela; Mendes, Inês; Pereira, André C; Pinto, Tiago; Acevedo, PelayoIn many Mediterranean ecosystems, animal tuberculosis (TB), caused by Mycobacterium bovis, an ecovar of Mycobacterium tuberculosis complex (MTBC), is maintained by multi-host communities. It is hypothesised that interspecies transmission is mainly indirect via shared contaminated environments. Therefore, identifying spatial areas where MTBC bacteria occur and quantifying space use by susceptible hosts might hel...

Ferreira, Eduardo M; Cunha, Monica; Duarte, Elsa Leclerc; Gonçalves, Renata; Pinto, Tiago; Mira, António; Santos, Sara MIn many Mediterranean ecosystems, animal tuberculosis (TB), caused by Mycobacterium bovis, is maintained by multi-host communities in which cattle and different wildlife species establish interaction networks contributing to M. bovis transmission and persistence. Most studies have addressed wildlife–cattle disease-relevant interactions, focusing on reservoir hosts, while disregarding the potential contribution ...
Effectiveness of permanent drift fences in reducing roadkill risk of amphibians
Pinto, Tiago; Sillero, Neftali; Mira, António; Sousa, Luis; Oliveira, André; Santos, SaraRoads are an important source of human economic progress, but also a threat to wildlife populations and natural habitats. Roads are responsible for the direct mortality of hundreds of millions of animals worldwide, with special negative effects for amphibians. Since the middle of the twentieth century, various types of mitigation measures have been constructed to reduce the negative effects of roads. However, d...
Selection of artificial warrens following the restocking of na endangered keyst...
Encarnação, Claudia; Sabino-Marques, Helena; Pinheiro, Paula; Santos, Sara Maria; Alves, Paulo Célio; Mira, AntónioThe European rabbit (Oryctolagus cuniculus) is an endangered species native to the Iberian Peninsula, playing a vital ecological role in Mediterranean ecosystems as prey for several threatened predators. Conservation efforts have been implemented to halt its decline, with a particular focus on the Iberian rabbit subspecies (Oryctolagus cuniculus algirus). Many conservation programmes involve restocking and habi...
Tell me where you go, and I’ll tell you where you die: landscape connectivity a...
Pinto, Tiago; Santos, Sara Maria; Mira, António; Sillero, NeftaliHuman overpopulation, development, and consequent activities such as land conversion and linear infrastructure expansion, are currently some of the main threats to biodiversity. Amphibians are especially affected because they depend on both aquatic and terrestrial habitats to complete their life cycles, which can be negatively impacted by roads, due to reduced landscape connectivity. Understanding animal moveme...
New Additions to the Mammal List Documented in the Portuguese Red Data Book
Mathias, Marua da Luz; Mira, António; Joaquim, Tapisso; Pita, Ricardo; Neves, Tomé; Cabral, João Alexandre; Barros, Paulo; Rainho, AnaThis study outlines the procedures used for collecting, processing, and categorizing data on 16 new mammal species for mainland Portugal, belonging to four taxonomic groups: Eulipotyphla (1), Chiroptera (4), Rodentia (2), and Cetacea (9). Data collection and processing encompassed field and lab work and bibliographic compilation. Data categorization involves, whenever possible, the assessment of the approximate...
Patch spatial attributes and time to disturbance affect the emergence of source...
Crispim-Mendes, Tiago; Roos, Deon; Ferreira, Clara; Paupério, Joana; Silva, João Paulo; Godinho, Sérgio; Alves, Paulo Célio; Mira, António; Beja, PedroUnderstanding the demography of local populations within ephemeral habitat patches is crucial for effective local (site-based) conservation management in spatially and temporally heterogeneous environments. Evidence suggests that species persisting in networks of ephemeral patches often exhibit source-sink dynamics, where certain local populations act as temporary sources at some time between initial colonizati...

Species-Specific Effects of a Sound Prototype to Reduce Bird Use of Powerline P...
Ribeiro-Silva, Joana; Ribeiro, Helder; Mira, António; Sillero, NeftalíPowerlines pose a significant threat to many bird species, impacting their conservation. Current research focuses on developing methods to mitigate bird mortality due to electrocution and collisions with powerlines. In this study, we designed a sound prototype to be installed on infrastructure poles, including powerlines, aiming to reduce their use by birds. We conducted bird surveys over 47 days, from February...
Understanding Roadkill Hotspots: Insights from Comprehensive Wildlife Roadkill ...
Mira, António; Garcia, Graça; Pedroso, Nuno; Manghi, Giovanni; Salgueiro, Pedro; Santos, SaraWildlife roadkill databases often compile valuable information regarding species, timing, and locations of roadkill incidents, with some databases also including details such as gender and age classes. As part of the “LIFE LINES - Linear Infrastructure Networks with Ecological Solutions” project, we aggregated roadkill data from various sources, including road operators, traffic police, and academic institution...
