Purpose The DANFLU-1 trial suggested lower incidence of hospitalizations for pneumonia and influenza, respiratory disease and all-cause mortality among older adults receiving high-dose (HD-IV) versus standard-dose (SD-IV) influenza vaccine. This study assessed the relative effectiveness of HD-IV versus SD-IV according to comorbidity in elderly individuals. Methods This was a post-hoc analysis of the DANFLU-1 randomized control...
Eruptions from the Katla central volcano occur through the overlying Mýrdalsjökull ice cap, meaning proximal deposits are usually not well preserved or exposed. Two nunataks, Enta and Klakksfjöll, crop out above the ice cap close to the Katla caldera rim and offer exceptional exposure of proximal rhyolitic eruptive products from this predominantly basaltic volcano. Geological mapping of these nunataks reveals silicic tephra wi...
Extensive regional variation in the phenology of insects and their response to temperature across N orth A mericaNARA Subscribed
Climate change models often assume similar responses to temperatures across the range of a species, but local adaptation or phenotypic plasticity can lead plants and animals to respond differently to temperature in different parts of their range. To date, there have been few tests of this assumption at the scale of continents, so it is unclear if this is a large‐scale problem. Here, we examined the assumption that insect taxa...
Insect phenological lability is key for determining which species will adapt under environmental change. However, little is known about when adult insect activity terminates and overall activity duration. We used community‐science and museum specimen data to investigate the effects of climate and urbanisation on timing of adult insect activity for 101 species varying in life history traits. We found detritivores and species wi...
The effects of temperature and light on both oxygen (O 2 ) production and gross photosynthesis were resolved in a benthic microalgal community by combining two‐dimensional (2D) imaging of O 2 and variable chlorophyll a (Chl a ) fluorescence. Images revealed a photosynthetically active community with spatial heterogeneity at the millimeter scale. Irradiance strongly increased pore‐water O 2 concentration, sediment net O 2 produ...
Tracing the biosynthetic source of essential amino acids in marine turtles using δ 13 C fingerprintsNARA Subscribed
Plants, bacteria, and fungi produce essential amino acids (EAAs) with distinctive patterns of δ 13 C values that can be used as naturally occurring fingerprints of biosynthetic origin of EAAs in a food web. Because animals cannot synthesize EAAs and must obtain them from food, their tissues reflect δ 13 C EAA patterns found in diet, but it is not known how microbes responsible for hindgut fermentation in some herbivores influe...
