Microbial oil production by Yarrowia lipolytica strains using glycerol as carbon sourceNARA Subscribed
Yeasts can produce microbial oil from hydrophobic substrates such as glycerol, a byproduct of the biodiesel industry that is often undervalued in the market. Yarrowia lipolytica is capable of degrading glycerol and is considered a model organism for studying lipid accumulation. Different yeast strains and culture conditions can result in varying lipid yields with distinct fatty acid profiles. Thus, in this study, five strains...
Intestinal Histomorphometric Alterations During Experimental Strongyloidiasis in Mice Treated with Rosmarinus officinalis Essential OilNARA Subscribed
Purpose Strongyloidiasis is an intestinal helminthiasis that can induce structural alterations in the intestinal mucosa during infection. The present study evaluated histomorphometric alterations of the small intestine in mice experimentally infected with Strongyloides venezuelensis and treated with Rosmarinus officinalis essential oil. Methods Infected animals were treated orally with R. officinalis essential oil (200 or 400...
Background and aims Legume residues are important organic inputs, but their effects depend on residue chemistry and application rate. This study examined how pea ( Pisum sativum ) and field bean ( Vicia faba ) residues with contrasting phytochemical compositions influenced soil functioning and subsequent barley growth, assessing how residue quality and dose shape soil responses. Methods A sandy loam soil was amended with resid...
From agro-industrial waste to microbial pigments: advances in production substrates and extraction technologiesNARA Subscribed
Microbial pigments have been gaining prominence as sustainable alternatives to synthetic dyes, which are often associated with environmental impacts and potential health risks. A wide range of microorganisms, including bacteria, fungi and yeasts, are capable of producing pigments of industrial interest. Despite their potential, large-scale production still faces challenges related to cultivation costs and, in particular, extra...
Traffic and functional polarization of macrophages in the areas of programmed interdigital cell death in the embryonic chickNARA Subscribed
In this study, we show that during digit development, the embryonic limb contains an abundant and widespread population of “resident macrophages” that precede the onset of interdigital cell death responsible for the separation of digit primordia. The use of cultures of interdigital mesoderm at different remodeling stages, and GFP+ transgenic embryos in which the distal part of the autopodium has been surgically replaced by a f...
Unravelling the molecular mechanisms of vegetative-to-reproductive transition in Cynara cardunculus by RNA-Seq analysisNARA Subscribed
Cynara cardunculus inflorescence plays a significant role in cheese manufacturing and human consumption due to the milk-clotting capacity and the production of edible immature capitula. Consequently, it is crucial to understand the complex cellular and molecular processes involved in the development of cardoon flowers. The current study used western wild cardoon in two developmental stages, vegetative and reproductive, to unde...
To advance understanding of meiofauna, key components of marine benthic ecosystems, an international team conducted a morphology-based taxonomic survey and workshop around São Miguel, the largest Azorean island, in 2019. The survey yielded critical baseline data on meiofaunal diversity and, despite taxonomic challenges that limited identification of certain taxa, laid a solid foundation for further research. To expand these fi...
Under the current global biodiversity crisis, there is a need for automated and noninvasive monitoring techniques that can gather large amounts of data cost‐effectively at various ecological scales, from local to large spatial scales. These data can then be analyzed to inform stakeholders and decision‐makers. One such technique is passive acoustic monitoring, which is commonly coupled with automatic identification of animal sp...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Oxygen Supersaturation Could Protect Reef‐Building Corals Against Acute Thermal StressNARA Subscribed
Ongoing climate change is constraining the availability of molecular oxygen (O 2 ) on coral reefs. The field has recently invested considerable resources to quantify the effects of hypoxia on corals. However, drivers of reef oxygen decline will not only expose corals to more frequent episodes of hypoxia but also limit peak daytime oxygen levels. Here, we test the theory of oxygen‐mediated thermal performance on three reef‐buil...
Understanding variation in home range size (HR) provides important insights into the underlying ecological processes driving space use. However, it remains unclear whether the interspecific allometric scaling of mammals' HR can also be consistently observed within species and for both sexes. To address this knowledge gap, we GPS‐tracked 349 resident individuals across Brazil, encompassing 18 mammal species. We estimated indivi...
Carbon footprint calculator for the Portuguese textile and clothing industry: development, application and validationNARA Subscribed
This study aimed to develop, implement, and validate a carbon footprint (CF) calculator to estimate greenhouse gas (GHG) emissions generated by Portugal´s Textile and Clothing Sector (TCS). To achieve this, the GHG Protocol and life cycle assessment (LCA) methodology were applied to develop the CF and analyse two textile and clothing companies (A and B). Validation was conducted using a self-assessment method that employed 2 o...
Climate change and human activity pose increasing challenges to endangered sea turtles, which are key species in many marine ecosystems worldwide. Among these challenges are the flooding and erosion of nesting beaches. In this perspective, we argue that existing methods and tools from coastal science and management hold significant, yet underused, potential for sea turtle conservation. We introduce a stepwise framework for int...
