Comparative performance and ecotoxicity assessment of Y2(CO3)3, ZnO/TiO2, and F...
Salazar, H.; Martins, P. M.; Batista, Daniela Miranda; Shejale, K. P.; Sharma, R. K.; Krishnapriya, R.; Ferdov, S.; Botelho, GabrielaThe application of nanomaterials to remove arsenic (As) from the water represents one of the 21 most promising remediation methods nowadays. In this study, three active materials, including 22 Y2(CO3)3), ZnO/TiO2, and Fe3O4, with different structural and morphological properties, were 23 evaluated for their As(V) adsorption capacity in contaminated water. Thus, the adsorption 24 behaviour was evaluated, includi...
Elevated temperature may reduce functional but not taxonomic diversity of funga...
Fenoy, Encarnación; Pradhan, Arunava; Pascoal, Cláudia; Rubio-Ríos, Juan; Batista, Daniela Miranda; Moyano-López, Francisco J.; Cássio, FernandaMounting evidence points to a linkage between biodiversity and ecosystem functioning (B-EF). Global drivers, such as warming and nutrient enrichment, can alter species richness and composition of aquatic fungal assemblages associated with leaf-litter decomposition, a key ecosystem process in headwater streams. However, effects of biodiversity changes on ecosystem functions might be countered by the presumed hig...
Contaminantes emergentes: uma perspetiva global e os seus efeitos nos organismo...
Batista, Daniela MirandaA contaminação ambiental por microplásticos (MPs) dos ecossistemas aquáticos tem vindo a aumentar por todo o mundo, sendo este tema de interesse global. Contudo, os seus efeitos nos organismos e processos dos ecossistemas de agua doce são pouco conhecidos, mas existe ainda a possibilidade de outros contaminantes (antibióticos, nanopartículas, etc) se ligarem aos MPs, tornando este um problema ainda mais preocup...
Are aquatic fungi able to evaluate microplastic impacts on leaf litter decompos...
Batista, Daniela Miranda; Pascoal, Cláudia; Cássio, FernandaMicroplastics (MPs) have been recognized as a threat, and an ecotoxicological risk for aquatic ecosystems. MPs toxicity is determined by their physical and chemical properties, including particle size, shape, surface area or polymer type. Aquatic hyphomycetes are a group of fungi that have the greatest ecological effects on freshwater ecosystems, as they are involved in a key process on these ecosystems, the de...
Interactive effects of microplastics and ciprofloxacin on aquatic microbial dec...
Batista, Daniela Miranda; Carvalho, Natália; Cássio, FernandaEnvironmental contamination by microplastics (MP) of aquatic ecosystems is increasing worldwide, making this thematic of global concern. Although it is still poor know their effects as individual contaminants, the possibility of other contaminants to bind MPs can overwhelm the problem. Plant litter decomposition is a key ecological process in freshwaters, where microbial decomposers, play an important role by t...
The increase in temperature overwhelms silver nanoparticle effects on the aquat...
Batista, Daniela Miranda; Pascoal, Cláudia; Cássio, FernandaThe effects of silver nanoparticles (AgNPs) have been largely explored, but there is still a lack of knowledge on their effects under the predicted changes in temperature as a consequence of climate change. The aim of the present study was to determine how leaf consumption by invertebrate shredders is affected by dietary exposure to AgNPs and AgNO3 and whether changes in temperature alter such effects. Also, re...
Is plastic a real threat to freshwater detrital ecosystem? A trophic approach
Batista, Daniela Miranda; Pradhan, Arunava; Pascoal, Cláudia; Cássio, FernandaPlastic pollution is a global problem with major impacts on the environment and the human health. Freshwater ecosystems are being subject to extensive pollution by plastics as they are the direct link between plastic wastes and marine ecosystems. However, the research on the impacts of plastics on freshwater detrital ecosystems and the organisms involved in this key process is limited. We assessed the impacts o...
Nanosilver impacts on aquatic microbial decomposers and litter decomposition as...
Batista, Daniela Miranda; Tlili, Ahmed; Gessner, Mark O.; Pascoal, Cláudia; Cássio, FernandaThe growing proliferation of silver nanoparticles (AgNPs) calls for detailed information on ecotoxicological effects, particularly on diverse communities and key ecosystem processes where impacts remain poorly known. This includes the decomposition of plant litter by fungi and bacteria in streams. Impacts are likely to depend on community composition, because species vary in their sensitivities to stressors. Th...
Effects of invasive clam (Corbicula fluminea) die-offs on the structure and fun...
Novais, Adriana; Batista, Daniela Miranda; Cássio, Fernanda; Pascoal, Cláudia; Sousa, Ronaldo Gomes1. Freshwater ecosystems are highly susceptible to the impacts of global climate change, including extreme events such as floods and droughts. These impacts may be influenced by the presence of widespread invasive alien species, such as the Asian clam Corbicula fluminea (Cyrenidae). 2. The high density and biomass attained by C. fluminea in the Minho River (NW Iberian Peninsula) are responsible for several ecol...
Impacts of silver nanoparticles in freshwater detrital food-webs in a warming s...
Batista, Daniela MirandaThe production and use of silver nanoparticles (AgNPs) has significantly grown over the last decade, increasing the risk that a fraction of NPs is transported to freshwater ecosystems. In these ecosystems, AgNPs and ionic silver released from dissolution of NPs can have toxic effects on aquatic species and compromise important ecosystem processes, such as plant litter decomposition. The research on the impacts ...
