Recent progress in marine mycological research in different countries, and pros...
Pang, Ka-Lai; Jones, E. B. Gareth; Abdel-Wahab, Mohamed A.; Adams, Sarah J.; Alves, Artur; Azevedo, Egídia; Bahkali, Ali H.; Barata, MargaridaEarly research on marine fungi was mostly descriptive, with an emphasis on their diversity and taxonomy, especially of those collected at rocky shores on seaweeds and driftwood. Subsequently, further substrata (e.g. salt marsh grasses, marine animals, seagrasses, sea foam, seawater, sediment) and habitats (coral reefs, deep-sea, hydrothermal vents, mangroves, sandy beaches, salt marshes) were explored for marin...
Invasive fish disrupt host-pathogen dynamics leading to amphibian declines
Rosa, Gonçalo M.; Ayala Botto, Gonçalo; Mitra, Amartya T.; Almeida, João Simões de; Hofmann, Max; Leung, William T.M.; Alves de Matos, António PedroSudden disease outbreaks may not necessarily reflect a recent pathogen introduction but may instead arise from the disruption of a host-pathogen equilibrium. Together with invasive species, emerging pathogens pose significant threats to biodiversity. The dynamics of each stressor have been studied separately, yet rarely when interacting. Using a 40-year dataset, we tested the hypothesis that the introduction of...
Restoration of Triticum aestivum Growth under Salt Stress by Phosphate-Solubili...
Belkebla, Nadia; Bessai, Sylia Ait; Melo, Juliana; Caeiro, Maria Filomena; Cruz, Cristina; Nabti, El-hafidSalinity causes significant agricultural losses in many areas in the world. Plant growth promoting bacteria (PGPB) are a promising solution to enhance plant growth and productivity under such stress conditions by different mechanisms, mainly phosphorous solubilization. This study aims to improve wheat seedling growth under salt stress by a halotolerant phosphorous-solubilizing bacterial strain. Soil sample was ...

Ocurrence of Ostreopsis in two temperate coastal bays (SW iberia): Insights fro...
Santos, Mariana; Oliveira, Paulo B.; Moita, Maria Teresa; David, Helena; Caeiro, Maria Filomena; Zingone, Adriana; Amorim, Ana; Silva, AlexandraThe benthic genus Ostreopsis contains toxic-bloom forming species and is an important cause of concern in warm-temperate and tropical waters. On the coast of Portugal, NE Atlantic, the occurrence of Ostreopsis cf. siamensis and Ostreopsis cf. ovata has been reported since 2008 and 2011, respectively. This work aims to understand the favorable conditions for high concentrations of Ostreopsis cells in the plankto...

Evaluation of the antiviral activity of an aqueous extract from Solidago virgau...
Mendes, Ana Rita; Lopo, Sílvia; Ascensão, Lia; Falé, Pedro; Serralheiro, Luisa; Caeiro, Maria FilomenaHerpes simplex virus type 2 (HSV-2) is widely distributed through the human population, infecting more than 500 million people globally [1]. Although typically causing mild diseases this virus may be responsible for severe infections, mainly in immunocompromised patients. Currently, there is a number of systemic antiviral agents against herpesvirus, the most commonly used being acyclovir and related drugs. Howe...
Use of drift substrates to characterize marine fungal communities from the west...
Azevedo, Egidia; Rebelo, Rui; Caeiro, Maria Filomena; Barata, MargaridaThis survey reports the occurrence, diversity and similarity of marine fungi associated with five categories of drift substrates (Arundo donax, Phragmites australis, Spartina maritima, "other stems" and driftwood) collected on four sandy beaches of the western coast of Portugal. "Other stems" and driftwood are composite samples with a variety of identified and unidentified pieces of non-woody and woody substrat...
