Historical vertebrate herbivory drives ontogenetic shifts in plant defense across oceanic islandsNARA Subscribed
Islands with contrasting herbivore histories provide a natural framework to investigate the evolution of plant defenses. Theory predicts that on islands with historically intense vertebrate herbivory, juveniles maintain strong defenses while adults may reduce them once out of reach, whereas islands lacking vertebrate browsers show minimal ontogenetic differences and generally lower defenses. Alternatively, when extinct herbivo...
Mass spectrometry-based metabolomics and chemometric analysis reveal host tissue-level classification of Aspergillus flavus isolatesNARA Subscribed
Mass spectrometry-based metabolomics has emerged as a powerful approach for investigating fungal metabolic diversity and identifying biomarkers related to pathogenicity and variability among isolates. Here, we characterized and distinguished Aspergillus flavus strains isolated from the leaves and roots of soybean plants via ultrahigh-performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS) integrated wi...
A combined structural, petrological, and anisotropy of magnetic susceptibility (AMS) study of the Cisuralian (285 ± 2 Ma) Cerro Redondo dacitic intrusion (Iberian Chain, NE Spain) has been conducted to reconstruct its emplacement kinematics and determine its 3D geometry at the outcrop scale. This small igneous body, covering only 0.17 km 2 , displays a well-defined magmatic foliation that is affected by asymmetrical, steeply p...
Regional Variation in Insularity Effects on Acorn Herbivory in European Oaks Challenges Predictions of Lower Herbivory on IslandsNARA Subscribed
Aim Ecological theory predicts lower herbivory on islands. However, most island‐mainland comparisons have focused on vegetative tissues, while reproductive structures remain understudied despite their direct influence on plant fitness and recruitment. This study investigates how insularity affects insect herbivory in oak ( Quercus ) acorns across multiple island‐mainland regions and explores the role of acorn traits (chemical...
In August 2024, a northern fur seal mortality event was observed on St. Paul Island, AK in the southeast (SE) Bering Sea. Ten seals in good body condition were found dead along with large accumulations of dead fish on Benson Beach located on St. Paul Island. Full necropsies of the five available adult seals, one pup, and several fish did not reveal any overt causes of death. Testing of tissues for the algal neurotoxins domoic...
The aquaculture of Octopus vulgaris is gaining interest due to its high demand, rapid growth, and nutritional value. However, significant challenges remain, particularly in rearing paralarvae to juveniles, mainly due to their specific nutritional needs. This study evaluates the impact of two bioactive compounds— Hytolive ® syrup (natural olive fruit extract rich in hydroxytyrosol) and black cumin seed oil (rich in thymoquinone...
Aim Plant specialised metabolites are highly diverse and serve various functions, yet the different forms of phytochemical complexity and their drivers are often not fully understood. In this context, islands provide a valuable opportunity to explore the drivers of phytochemical diversity and its adaptive significance, owing to their unique physical features and markedly different biotic and abiotic pressures compared to the m...
Serpentine soils, known for high heavy metal content and low nutrients, create harsh conditions for plants and herbivores. Although previous research has explored how serpentine soils affect herbivory, most studies have been restricted to a specific region, and the mechanisms involved remain unclear. Here, we conducted a large‐scale study across 78 plant species from California, Spain, and Sweden, comparing insect herbivory an...
Chromosome-Y haplogroups in Asturias (Northern Spain) and their association with severe COVID-19NARA Subscribed
The main objective of this study was to determine whether the common Y-haplogroups were be associated with the risk of developing severe COVID-19 in Spanish male. We studied 479 patients who required hospitalization due to COVID-19 and 285 population controls from the region of Asturias (northern Spain), They were genotyped for several polymorphisms that define the common European Y-haplogroups. We compared the frequencies bet...
An Approach to Assessing the Impact of Hurricane Matthew on Meiofaunal Communities in Sandy Beach EnvironmentsNARA Subscribed
Hurricanes are natural periodic events that disrupt marine ecosystems along their path, altering the distribution and abundance of organisms. In October 2016, Hurricane Matthew struck the Santa Marta region (Colombia) and impacted its coastal zone, yet there have been insufficient studies to measure its effects. The aim of this study was to assess the impact of Hurricane Matthew on the meiofaunal community in the region. To ac...
