The evaluation of pollen concentrations with statistical and computational methods on rooftop and on ground level in Vienna – How to include daily crowd-sourced symptom data

World Allergy Organization Journal, 2019
Background: It is recommended to position pollen monitoring stations on rooftop level to assure a large catchment area and to gain data that are representative for a regional scale.

Pollenkitt is associated with the collectability of Malvoideae pollen for corbiculate bees

Journal of Pollination Ecology, 2023
Pollen grains of Malvoideae (Malvaceae) which corbiculate bees cannot collect constitute a floral filter that excludes pollen-collecting bumble bees and honey bees from exploiting pollen resources.

Chloride fluxes in lily pollen tubes: a critical reevaluation

, 2004
Microelectrodes, made from a Cl?-selective liquid ion exchanger previously used to measure putative Cl- fluxes in Lilium longiflorum pollen tubes, were characterized. The electrodes were poorly selective, possessing only about 10-fold selectivity for Cl?
