Using individual-based demographic modelling to estimate the impacts of anthrop...
Marques, Teresa; Crispim-Mendes, Tiago; Palma, Luís; Pita, Ricardo; Moreira, Francisco; Beja, PedroWildlife anthropogenic mortality is increasing worldwide, yet there is limited understanding regarding its population-level impacts. Territorial species stand out in this context, as they possess distinctive characteristics that are often overlooked but may significantly affect their vulnerability. In particular, population impacts may depend on the level and spatial distribution of additional mortality risk ac...
GEE_xtract: High-quality remote sensing data preparation and extraction for mul...
Valerio, Francesco; Godinho, Sérgio; Marques, Teresa; Crispim-Mendes, Tiago; Pita, Ricardo; Silva, João PauloEnvironmental sensing via Earth Observation Satellites (EOS) is critically important for understanding Earth’ biosphere. The last decade witnessed a “Klondike Gold Rush” era for ecological research given a growing multidisciplinary interest in EOS. Presently, the combination of repositories of remotely sensed big data, with cloud infrastructures granting exceptional analytical power, may now mark the emergence ...
High-resolution species distribution modelling reveals spatio-temporal variabil...
Crispim-Mendes, Tiago; Valerio, Francesco; Marques, Teresa; Pita, Ricardo; Godinho, SérgioContext: Species distribution models (SDMs) may provide accurate predictions of species occurrence across space and time, being critical for effective conservation planning. Objectives: Focusing on the little bustard (Tetrax tetrax), an endangered grassland bird, we aimed to: (i) characterise the drivers of the species distribution along its key phenological phases (winter, breeding, and post-breeding); and (ii...
Multi-temporal remote sensing of inland surface waters: A fusion of sentinel-1&...
Valerio, Francesco; Godinho, Sérgio; Ferraz, Gonçalo; Pita, Ricardo; Gameiro, João; Siva, Bruno; Marques, Teresa; Siva, João PauloInland freshwaters are essential in maintaining ecological balance and supporting human development. However, comprehensive water data cataloguing remains insufficient, especially for small water bodies (i.e., ponds), which are overlooked despite their ecological importance. To address this gap, remote sensing has emerged as a possible solution for understanding ecohydrological characteristics of water bodies, ...
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...

Valério, Francesco; Godinho, Sérgio; Ferraz, Gonçalo; Pita, Ricardo; Gameiro, João; Silva, Bruno; Marques, Ana Teresa; Silva, João PauloInland freshwaters are essential in maintaining ecological balance and supporting human development. How ever, comprehensive water data cataloguing remains insufficient, especially for small water bodies (i.e., ponds), which are overlooked despite their ecological importance. To address this gap, remote sensing has emerged as a possible solution for understanding ecohydrological characteristics of water bodies,...
