This study analyses cardiorespiratory mortality rates (CARDIO) and their association with air pollutants - particulate matter aerodynamic diameters lower of equal to 10 or 2.5 (µm) (PM10, PM2.5), carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3) meteorological variables (temperature, humidity, wind speed, direction) in the Lisbon (LMA) Porto (PMA) metropolitan areas from 2011 2020. Monthly reveal regional patterns seasonal variations. The results show that PMA had a higher average...
Abstract The rapid flow fluctuations experienced downstream of hydropeaking facilities can alter the river hydromorphology. Given dependence riverine fish on physical habitat, those alterations have potential to change physiology and behaviour fish. We assessed whether artificial velocity refuges mitigated physiological behavioural consequences for Iberian barbel ( Lucio barbus bocagei ). Hydropeaking trials were conducted in an indoor flume equipped with deflectors that created low areas...
Flow regime is a fundamental driver in fluvial ecosystems, shaping habitat structure and biodiversity, sustaining ecological integrity. Fish respond to flow fluctuations but whether aspects of variability represent organism-level stressors poorly understood. To find existing evidence fish responses (natural or anthropogenic), it resulted quantifiable stress (i.e. departure from homeostasis), we reviewed literature on the physiological exposed flow. Among 58 articles that identified be...
Hydropeaking is the rapid change in water flow downstream of a hydropower plant, driven by changes daily electricity demand. These fluctuations may produce negative effects freshwater fish. To minimize these impacts, previous studies have proposed habitat enhancement structures as potential mitigation measures for salmonids. However, recommendation cyprinids remains scarce and their unknown. In this study, under simulated hydropeaking base-flow conditions are examined Iberian barbel...
Abstract In the 19th century, B ritish polecat suffered a demographic contraction, as consequence of direct persecution, reaching its lowest population in years that preceded F irst W orld ar. The is now recovering and expanding throughout Britain, but introgressive hybridization with feral ferrets has been reported, which could be masking true range introducing domestic genes into species. We used fragment mitochondrial DNA control region 11 microsatellite loci to characterize frequency...
Food fraud refers to deceptive practices conducted for economic gain, and incidents of such are often reported in the media scientific literature. However, little is known about how European consumers perceive food fraud. To address this gap, a study explored Portuguese consumers' knowledge perceptions using qualitative methods as free word association semi-structured interviews. For research, 340 participants were recruited, providing 911 valid words, classified into categories, major...
Lentiviral vectors are among the most efficient tools for gene delivery into mammalian cells. A major goal of lentiviral systems is to develop that can efficiently target specific cell types. In present work, we attempt generate viral particles targeting delivery. We have used CCR5-positive cells as our strategy. Therefore, developed a novel Sindbis pseudotyped vector where receptor binding envelope protein was modified directly encode single-chain antibody fragment (scFv) against CCR5...
Assessment of habitat and water quality the Portuguese Febros River one its tributariesA physical, chemical biological characterisation river systems is needed to evaluate their ecological establish restoration programs.Aquatic benthic macroinvertebrates have proven be among most reliable cost-effective assessment tools for in streams throughout world.During year seasonal surveys, state tributaries, Jaca Creek, were evaluated terms habitat, quality, using as indicators.These watercourses...
The rapid river flow variations due to hydropower production during peak demand periods, known as hydropeaking, causes several ecological impacts. In this study, we assessed the potential of an overhead cover and velocity-refuge structure in indoor flume indirect hydropeaking mitigation measure for cyprinid species Iberian barbel (Luciobarbus bocagei). We designed a lab-scale LUNKERS-type using two different materials which were used separately: Wood (opaque) acrylic (transparent), tested...
Political responses to the COVID-19 pandemic led changes in city soundscapes around globe. From March October 2020, a consortium of 261 contributors from 35 countries brought together by Silent Cities project built unique soundscape recordings collection report on local acoustic urban areas. We present this here, along with metadata including observational descriptions areas contributors, open-source environmental data, confinement levels and calculation descriptors. performed technical...
Due to peak electricity demand, hydropeaking introduces rapid and artificial flow fluctuations in the receiving river, which alters river hydromorphology, while affecting downstream ecological integrity. The impacts of have been addressed flumes rivers. However, few studies propose mitigation solutions based on fish responses. objective this communication was assemble methods outputs flume research focused Iberian cyprinids present recommendations be used by freshwater scientists hydropower...

Abstract Hydropeaking caused by small‐scale hydropower plants creates rapid changes in the intensity, frequency, and persistence of river flows. These can induce stress fish across all life‐stages and, may negatively impact communities. Rapid increases flow velocity cause to avoid unstable habitats, seeking out nearby refuges reduce their energy expenditure. A lateral flow‐refuge constructed from maritime plywood (0.4 m wide × 0.5 long 0.4 high) was installed left bank, 40 downstream Bragado...
Gobio lozanoi , from the River Febros northern Portugal, contained female Philometra ovata in body cavity causing abdominal swelling. A mild chronic inflammation and some tissue necrosis were observed infected fish. Significant correlations found between occurrence of infection host length, gonado‐somatic index; intensity condition factor.
Downstream of small-scale hydropower plants (SHPs), the intensity, frequency and persistence hydropeaking events often cause an intolerable stress on fish all life stages. Rapid increases in flow velocity result avoiding unstable habitats seeking refuge to reduce energy expenditure. To understand movements habitat use native Iberian cyprinids a high-gradient peaking river, 77 individuals were PIT tagged downstream Bragado SHP North Portugal. Tagged species included Pseudochondrostoma...
Abstract An increase in the demand for renewable energy is driving hydropower development and its integration with variable sources. When produced flexibly from plants, it causes rapid frequent artificial flow fluctuations rivers, a phenomenon known as hydropeaking. Hydropeaking associated hydrological alterations cause multiple impacts on riverine habitats cascading effects ecosystem functioning structure. Given significance of ecological socio‐economic implications, mitigation hydropeaking...
Hydropower can have significant impacts on riverine ecosystems due to hydropeaking (i.e., artificial rapid and short-term fluctuations in water flow levels downstream upstream of hydropower stations) that negatively affect fish. However, when it comes analyzing species habitat use availability above below small plants (SHPPs), studies conducted at the microhabitat scale are scarcer, particularly Mediterranean rivers. The goal this study is assess seasonal (early late summer) size-related...
Summary Patella candei gomesii is morphologically plastic comprising two ecomorphs. The “smooth limpet” characteristic of the eulittoral zone, whereas “fly mainly found higher in shore, on splash zone exposed areas. Their reproductive strategies are poorly understood. This study investigated cycles ecomorphs using histological techniques. annual were to be similar. Both sexes exhibited synchronous patterns and mature most year. In April, significant increases observed relative volume...
Abstract Dam construction and streamflow regulation are increasing throughout the world, with impacts in impounded aquatic ecosystems. Hydropower dams, some of them causing a phenomenon called “hydropeaking” during their operation, known for having variety on downstream biota, particularly fish, respective habitat. This can result significant changes, from community (e.g., fish assemblage structure) to individual level physiological behavioural adjustments). Researchers managers involved...
