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...
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...
A Neuron-Like Cellular Model for Severe Tinnitus Associated with Rare Variations in the ANK2 GeneNARA Subscribed
Tinnitus is the perception of sound without an external source, often associated with changes in the auditory pathway and different brain regions. Recent research revealed an overload of missense variants in the ANK2 gene in individuals with severe tinnitus. ANK2 , encoding ankyrin-B, regulates axon branching and inhibits microtubule invasion. Missense mutations in ANK2 may promote excessive axonal branching and the formation...
