Spatiotemporal trends in abundance and richness of elasmobranchs in Frégate Island, SeychellesNARA Subscribed
Elasmobranch diversity has been poorly investigated within the Seychelles archipelago. The present study aimed to describe the spatial-temporal changes in the species richness and abundance of elasmobranchs on Frégate Island, Seychelles. Baited Remote Underwater Video Systems (BRUVS) were performed between May 2019 and December 2022. A total of 18 elasmobranch species were observed, comprising nine sharks and nine rays. Most s...
Response of phytoplankton to coastal upwelling: The importance of temporal and spatial scalesNARA Subscribed
The Western Iberian Coast (WIC) is characterized by a dynamic coastal upwelling system with interactions between oceanographic features and continental river run‐off. The present study investigates the spatio‐temporal variability in the concentrations of Chlorophyll a (Chl a ) and turbidity, and their relationships with physical and other biogeochemical properties along the entire coast of Portugal, as well as the response of...
Mannosylerythritol lipids (MELs) are a group of biosurfactants with a wide range of potential applications, due to their excellent tensioactive properties, biocompatibility, and biodegradability. One of the envisioned uses for MELs is in bioremediation in marine and terrestrial environments. However, knowledge regarding their ecotoxicity is limited. The current costs of production for this biosurfactant are too high to make it...
Low-Cost, Deep-Sea Imaging and Analysis Tools for Deep-Sea Exploration: A Collaborative Design StudyOA Marine
A minuscule fraction of the deep sea has been scientifically explored and characterized due to several constraints, including expense, inefficiency, exclusion, and the resulting inequitable access to tools and resources around the world. To meet the demand for understanding the largest biosphere on our planet, we must accelerate the pace and broaden the scope of exploration by adding low-cost, scalable tools to the traditional...
MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugalNARA Subscribed
Mammals are threatened worldwide, with ~26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mammals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems functionality and resilience, and therefore information o...
A novel pathway for the synthesis of inositol phospholipids uses cytidine diphosphate ( CDP )‐inositol as donor of the polar head groupNARA Subscribed
Summary We describe a novel biosynthetic pathway for glycerophosphoinositides in R hodothermus marinus in which inositol is activated by cytidine triphosphate ( CTP ); this is unlike all known pathways that involve activation of the lipid group instead. This work was motivated by the detection in the R . marinus genome of a gene with high similarity to CTP : L ‐ myo ‐inositol‐1‐phosphate cytidylyltransferase, the enzyme that s...
Evolution of the biosynthesis of di‐ myo ‐inositol phosphate, a marker of adaptation to hot marine environmentsNARA Subscribed
Summary The synthesis of di‐ myo ‐inositol phosphate (DIP), a common compatible solute in hyperthermophiles, involves the consecutive actions of inositol‐1‐phosphate cytidylyltransferase (IPCT) and di‐ myo ‐inositol phosphate phosphate synthase (DIPPS). In most cases, both activities are present in a single gene product, but separate genes are also found in a few organisms. Genes for IPCT and DIPPS were found in the genomes of...
