Rhinovirus thread
This study tested how rhinovirus transmits. (Dick et al. 1987.)
Briefly, ppl infected w/ rhinovirus played cards for 12 hours w/ uninfected ppl. Some of the uninfected were stopped from touching face. Rate of attack the same.
They then stopped all air exchange between the groups: ZERO infected.

Increased time between flowering and leafing due to global warming is seen in Betulaceae species (i.e., Alnus glutinosa, Betula pendula and Corylus avellana) in Central Europe. This “phenological decoupling” can increase plant stress in Betulaceae populations and impact the distribution and phenology of these species during the coming decades.
New paper written with colleagues from Spain using Pan-European Phenology (PEP725) data #aerobiology #phenology #climatechange https://link.springer.com/article/10.1007/s00484-022-02398-9
SpringerLinkClimate change related phenological decoupling in species belonging to the Betulaceae family - International Journal of BiometeorologyBetulaceae species are anemophilous, and allergens from their pollen are a major cause of respiratory allergies in temperate areas where they are widely distributed. It is expected that, due to the strong influence of temperature on Betulaceae phenology, global warming will impact both the distribution and phenology of these species during the coming decades. This study examines potential decoupling of flowering and leafing phenophases in Betulaceae species (i.e. Alnus glutinosa, Betula pendula and Corylus avellana) over long-term (1951–2015) and as shorter (15-year) periods. Phenological phases for flowering and leaf unfolding of Betulaceae species from the Pan-European Phenology (PEP725) database were examined along with maximum and minimum daily temperature data for the periods September–October-November (SON), December-January–February (DJF) and March–April-May (MAM). Significant increases in temperature since 1951 have been recorded in the relevant chilling and forcing periods. Both flowering and leaf unfolding phenophases are advancing, but flowering is advancing faster than leaf unfolding. This is increasing the time between phenophases, although analysis of 15-year periods shows that the pattern of change was not constant. The results presented here represent the most comprehensive analysis of flowering and leaf unfolding phenophases of Betulaceae species using the PEP725 database to date. It is expected that these changes to Betulaceae phenology will continue and that global warming–related phenological decoupling will increase plant stress in Betulaceae populations in central Europe.
#introduction time
I’m an Environmental Scientist with a focus on #aerobiology and #phenology
I also teach geography and environmental management so will be on here following topics such as #climatechange #microplastics and #pollution
I’m a bird ringer/bird bander and have an interest in #entomology especially moths. There might also be the occasional rant about politics (green woke leftie).
Oh, and dog videos
