Estudo das populações de pequenos mamíferos através da análise de egagrópilas d...
Bettencourt, Sofia; Vale-Gonçalves, Hélia; Ferreira, Rafael; Carrola, João SoaresThe study of small mammal populations can be carried out through direct methods involving their capture through traps, and indirect non-invasive methods such as camera trapping, prospecting and collection of signs of presence and analysis of barn owl's regurgitated pellets. The barn owl (Tyto alba) is a nocturnal bird of prey with a global distribution, with the exception of the Arctic regions. This species fee...
A PESCA LÚDICO-DESPORTIVA À CARPA (CYPRINUS CARPIO):: O CASO DO CARP FISHING
Carrola, João Soares; Pereira, José; Martinho, AntónioFishing in continental waters has long ceased to be practiced solely for food purposes and more contemporary societies recognise that this activity has a growing recreational and sporting value, whose dynamics are capable of generating important social and economic resources for the development of some regions of our country, especially the less developed inland regions. Technological developments in fishing eq...
Population structure of the European seabass (Dicentrarchus labrax) in the Atla...
Kulzer, Rafael; Silva, Rodolfo Miguel; Rocha, Ana Filipa; Carrola, João Soares; Seabra, Rosária Catarino; Rocha, Eduardo; Correia, Alberto TeodoricoThe European seabass (Dicentrarchus labrax) is one of the most emblematic coastal fish species in the Northeast Atlantic, with high commercial value for fisheries and aquaculture, and importance for sport and recreational fishing. Despite its socio-economic importance, the Iberian divisions, Cantabrian Sea (8c) and the Atlantic Iberian waters (9a), defined by the International Council for the Exploration of the...
Evaluation of oxidative stress and apoptosis responses in zebrafish (Danio reri...
Ribeiro, Ondina; Félix, Luís; Ribeiro, Cláudia; Tiritan, Maria Elizabeth; Carrola, João SoaresBackground: The emergence of new psychoactive substances (NPS) in the worldwide drug market raises huge concerns over public health, drug policy and environmental adverse effects [1]. Butylone (BTL) is a synthetic chiral cathinone [2] reported in wastewater effluents and despite its increasing presence in freshwater ecosystems, no studies were found on the BTL toxic evaluation in fish, including the well-known ...
Butylone effects on swimming behaviour and biochemical parameters on Daphnia magna
Carvalho, Ana Rita; Gonçalves, Virgínia M. F.; Tiritan, Maria Elizabeth; Carrola, João Soares; Castro, Bruno; Ribeiro, Ana Rita Lado RibeiroBackground: Psychoactive substances (e.g. cathinones) may be detected in environmental samples, posing risks to wildlife and human health [1, 2]. Butylone (BTL) is a chiral synthetic cathinone available as a racemate [1]. Nevertheless, both human metabolism and biodegradation at wastewater treatment plants may be enantioselective causing changes in its enantiomeric fraction (EF) [2]. Therefore, enantiomers may ...
Exploring the swimming behavior of Daphnia magna exposed to a mixture of five p...
Pereira, Ana Sofia; Carvalho, Ana Rita; Couto, Cristina; Carrola, João Soares; Castro, Bruno; Ribeiro, CláudiaBackground: Psychoactive substances (PAS) are commonly found in freshwater ecosystems increasing concern about the potential negative impacts on non-target organisms, such as aquatic invertebrates [1]. Indeed, the environmental occurrence of amphetamine (AMP), and recreative drugs as 3,4-methylenedioxymethamphetamine (MDMA), 3,4-methylenedioxyamphetamine (MDA), and synthetic cathinones as butylone (BTL) and 3,4...
Environmental contamination as a source of multi-toxics via maternal exposure a...
Carrola, João Soares; Gonçalves , Carla; Bento, Alexandra; Dinis-Oliveira , Ricardo Jorge; Leal, SandraBackground: Environmental pollution exposes human to various toxics. Food is one main route of toxic exposure, encompass pesticides, per- and polyfluoroalkyl substances (PFAS), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), metals and nanoplastics [1]. Maternal exposure is a concern due to rising childhood neurodevelopmental disorders like autism spectrum disorders (ASD) [1,2] and en...
A POLUIÇÃO DO SOLO: CAUSAS, FONTES E PRINCIPAIS POLUENTES
Ribeiro, Ondina; Briones, Maria J.L.; Ribeiro, Cláudia; Natal-da-Luz, Tiago; Sousa, João Ricardo; Carrola, João SoaresSoil is an important resource for ecosystems, wildlife and agriculture. Since the industrial revolution, thousands of compounds have been used, produced and released involuntarily or even voluntarily (i.e. pesticides and bombs) into the environment, affecting the soil. Different sources and different types of pollutants will affect soil fauna, aquatic ecosystems and food chains. These compounds can bioaccumulat...
Genotoxicidade na minhoca Eisenia fetida exposta a metafedrona e cetamina
Ribeiro, Ondina; Natal-da-Luz, Tiago; Ribeiro, Cláudia; Sousa, João Ricardo; Gaivão, Isabel; Carrola, João SoaresA metafedrona e a cetamina são duas substâncias psicoativas (SPAs) utilizadas para fins recreativos e que podem ser detetadas nos ecossistemas terrestres devido à irrigação dos solos com águas contaminadas, aplicação de lamas provenientes de estações de tratamento de águas residuais, entre outros. Apesar de chegarem aos solos, pouco se sabe acerca dos efeitos tóxicos que as SPAs podem induzir nos organismos ter...
Avaliação do efeito tóxico da metafedrona em minhocas da espécie Eisenia fetida...
Ribeiro, Ondina; Pinto, Vera; Natal-da-Luz, Tiago; Sousa, João Ricardo; Ribeiro, Cláudia; Carrola, João SoaresO aumento do consumo de substâncias psicoativas (SPAs) tem gerado preocupação ambiental, devido ao consequente aumento de SPAs nos ecossistemas de água doce e terrestre. A metafedrona (3-MMC) é uma catinona sintética excretada na urina após o seu consumo, podendo chegar ao ambiente. Devido à presença das SPAs no solo, torna-se importante estudar os efeitos que podem ter nos organismos edáficos. Assim, o objetiv...
