Two new species of Nanofrustulum (Bacillariophyta) from temporary rivers in the...
Morales, Eduardo; Novais, Maria Helena; García, María Luján; Maidana, Nora; Morais, ManuelaTwo new Nanofrustulum species, N. lucectorii sp. nov. and N. ibericum sp. nov. are described from temporary streams in southern Portugal based on light and electron microscopy observations. Nanofrustulum lucectorii sp. nov. is characterised by elliptic valves with broadly rounded apices, spines with a solid core, an apically elliptic base, a flattened body, and spatulate, serrate tips that are wider than the sp...

Fragilaria odeloucaensis sp. nov. (Bacillariophyta, Fragilariaceae) a diatom fr...
Morales, Eduardo; Novais, Maria Helena; Wetzel, Carlos; Ector, Luc; Morais, Maria ManuelaA new species of araphid diatom is described from a temporary stream in southern Portugal, Fragilaria odeloucaensis sp. nov., which belongs to the group of Fragilaria with widely linear to lanceolate valve outline, spaced striae, lacking spines, and with well-developed apical pore fields. The new taxon can be distinguished based on five unique features within this group, the lanceolate valves with capitate apic...
Benthic diatom community dynamics in Mediterranean intermittent streams: Effect...
Novais, Maria Helena; Morales, Eduardo; Marchã Penha, Alexandra; Potes, Miguel; Bouchez, Agnès; Barthès, Amélie; Costa, Maria João; Salgado, RuiThe study of intermittent rivers is a critical and timely issue due to theirworldwide increase, triggered by several causes including climate change. The need to understand the response of intermittent river biota to water intermittency led us to conduct this study using benthic diatoms collected in southern Portugal. Benthic diatomswere explored in terms of assemblages, diversity indices, the Specific Pollutio...
FACTORS ASSOCIATED WITH MORTALITY IN PATIENTS HOSPITALIZED WITH COVID-19: PROSP...
VENCES, MIGUEL ANGEL; Pareja Ramos, Juan José; Otero , Paula; Veramendi-Espinoza, Liz E.; Vega-Villafana, Melissa; Mogollón-Lavi, JulissaAim: To determine the associated factors with mortality of adult patients hospitalized with COVID-19. Methods: We conducted a prospective cohort study and included patients older than 18 years hospitalized with the diagnosis of SARS-CoV-2 infection. Those patients with a positive rapid serological test on admission, but no respiratory symptoms nor compatible images were excluded. We collected the data from clin...
AVALIAÇÃO DA INTEGRIDADE ECOLÓGICA DE UM RESERVATÓRIO NA REGIÃO MEDITERRÂNICA: ...
Morais, Maria Manuela; Novais, Maria Helena; Penha, Alexandra; Nunes, Susana; Morales, EduardoÉ objetivo do presente trabalho apresentar e interpretar resultados físico-químicos e fitoplanctónicos da albufeira do Enxoé, situado na bacia do Guadiana no sul de Portugal. Este é um sistema eutrofizado, com potencial ecológico inferior a Bom (critérios da Diretiva Quadro da Água), sendo fundamental conhecer o funcionamento espacial e temporal do sistema para que, futuramente, em conjunto com as entidades res...
