Acoustic detection and occupancy models: A systematic review with insights for ...
Martins, Frederico; Segurado, Pedro; Marques, J. TiagoWildlife management requires monitoring to infer spatiotemporal changes in the distribution or abundance of species and communities of organisms. Technological advancements have increasingly facilitated monitoring species through new data collection methods. Such technological advancements include small-sized acoustic recording devices that can record a wide range of sound frequencies, making them especially su...
Gathering information of cryptic species: Insights from Integrated Occupancy M...
Martins, Frederico; Barros, Paulo; Cabral, João; Segurado, Pedro; Marques, J. TiagoEffective conservation planning relies on an adequate understanding of species occurrence at both individual and community levels. However, detecting some species presents a challenge, and the efficiency of sampling methods varies. Data integration from multiple methods is a natural solution to address these issues and enhance species parameter estimation. This study explores the benefits of combining sampling ...

A dataset of acoustic measurements from soundscapes collected worldwide during ...
Challéat, Samuel; Farrugia, Nicolas; Froidevaux, Jérémy S. P.; Gasc, Amandine; Pajusco, Nicolas; Abrahams, Carlos R.; Acevedo-Charry, OrlandoPolitical responses to the COVID-19 pandemic led to changes in city soundscapes around the globe. From March to October 2020, a consortium of 261 contributors from 35 countries brought together by the Silent Cities project built a unique soundscape recordings collection to report on local acoustic changes in urban areas. We present this collection here, along with metadata including observational descriptions o...
The ADnet Bayesian belief network for alder decline: Integrating empirical data...
Gomes Marques, Inês; Vieites-Blanco, Cristina; Rodríguez-González, Patricia M.; Segurado, Pedro; Marques, Marlene; Barrento, Maria J.The globalization in plant material trading has caused the emergence of invasive pests in many ecosystems, such as the alder pathogen Phytophthora ×alni in European riparian forests. Due to the ecological importance of alder to the functioning of rivers and the increasing incidence of P. ×alni-induced alder decline, effective and accessible decision tools are required to help managers and stakeholders control t...
The Biological Assessment and Rehabilitation of the World’s Rivers: An Overview
Feio, Maria João; Hughes, Robert M.; Callisto, Marcos; Nichols, Susan J.; Odume, Oghenekaro N.; Quintella, Bernardo R.; Kuemmerlen, MathiasThe biological assessment of rivers i.e., their assessment through use of aquatic assemblages, integrates the effects of multiple-stressors on these systems over time and is essential to evaluate ecosystem condition and establish recovery measures. It has been undertaken in many countries since the 1990s, but not globally. And where national or multi-national monitoring networks have gathered large amounts of d...
Evaluation of the trophic status in a Mediterranean reservoir under climate cha...
Almeida, Carina; Branco, Paulo; Segurado, Pedro; Ramos, Tiago B.; Ferreira, Teresa; Neves, Ramiro; Oliveira, Rodrigo ProençaThis study describes an integrated modelling approach to better understand the trophic status of the Montargil reservoir (southern Portugal) under climate change scenarios. The SWAT and CE-QUAL-W2 models were applied to the basin and reservoir, respectively, for simulating water and nutrient dynamics while considering one climatic scenario and two decadal timelines (2025–2034 and 2055–2064). Model simulations s...
Landscape connectivity affects individual survival in unstable patch networks: ...
Serrano, Filipe; Pita, Ricardo; Mota-Ferreira, Mário; Beja, Pedro; Segurado, Pedro1. The loss of connectivity is among the main threats for species occupying freshwater pond networks. Landscape connectivity can impact the persistence of patchy populations by reducing movement rates among ponds, thereby increasing the likelihood of local extinctions in source–sink systems, and reducing the probability of colonisation following extinctions. In addition, loss of connectivity may also reduce sur...
Predicting the ecological status of rivers and streams under different climatic...
Molina-Navarro, Eugenio; Segurado, Pedro; Branco, Paulo; Almeida, CarinaFreshwater systems have increasingly been subjected to a multitude of human pressures and the re-establishment of their ecological integrity is currently a major worldwide challenge. Expected future climate and socioeconomic changes will most probably further exacerbate such challenges. Modelling techniques may provide useful tools to help facing these demands, but their use is still limited within ecological q...
Biodiversidade aquática e qualidade de rios em eucaliptais certificados no cent...
Oliveira, João Manuel; Paulino, João Carlos; Segurado, Pedro; Rosado, Joana; Rivaes, Rui Pedro; Fernandes, Fátima; Serafim, Pedro; Ferreira, TeresaEm Portugal, mais de 150.000 ha de plantações de eucalipto (Eucalyptus globulus) são já geridas em conformidade com os sistemas internacionais de certificação. O objetivo deste trabalho foi o de avaliar a biodiversidade e a qualidade ecológica de pequenos rios associados a este tipo de povoamentos, usando diversas comunidades aquáticas – peixes, anfíbios e macroinvertebrados – bem como um índice de condição mor...
