Land-Use and Height of Pollen Sampling Affect Pollen Exposure in Munich, Germany

open access: yesAtmosphere, 2020
Airborne pollen concentrations vary depending on the location of the pollen trap with respect to the pollen sources. Two Hirst-type pollen traps were analyzed within the city of Munich (Germany): one trap was located 2 m above ground level (AGL) and the ...

The influence of self-pollen deposition on female reproductive success in a self-incompatible plant, Akebia quinata

open access: yesFrontiers in Plant Science, 2022
Geitonogamy is inevitable in hermaphrodite and monecious. Even for self-incompatible species, the negative effects of self-pollen are unavoidable when geitonogamous or self-mating occurs.

History of Picea abies in west central Sweden [PDF]

open access: yes, 2006
Early Holocene Picea megafossils found in west central Sweden have challenged the prevailing theory based on pollen analysis that Picea migrated to Scandinavia during the second half of the Holocene.

Pollen grading prediction scale for patients with Artemisia pollen allergy in China: A 3‐day moving predictive model

open access: yesClinical and Translational Allergy, 2023
Background Artemisia pollen is the most prevalent outdoor aeroallergen causing respiratory allergies in Beijing, China. Pollen allergen concentrations have a direct impact on the quality of life of those suffering from allergies.

Fatty acid composition of pollen and the effect of two dominant fatty acids (linoleic and oleic) in pollen and flour diets on longevity and nutritional composition of honey bees (apis mellifera) [PDF]

open access: yes, 2006
The size of the apiculture industry in Western Australia (W.A.) is one of the smallest in the nation but the production of pollen and honey per colony is the highest in Australia.

Variation in pollen-donor composition among pollinators in an entomophilous tree species, Castanea crenata, revealed by single-pollen genotyping. [PDF]

open access: yesPLoS ONE, 2015
BACKGROUND:In plants, reproductive success is largely determined by the composition of pollen (i.e., self-pollen and outcross-pollen from near and distant pollen-donors) transported as a result of pollinator foraging behavior (e.g., pollen carryover ...

Effects of post-translational modifications catalysed by pollen transglutaminase on the functional properties of microtubules and actin filaments [PDF]

open access: yes, 2009
TGases (transglutaminases) are a class of calcium-dependent enzymes that catalyse the interactions between acyl acceptor glutamyl residues and amine donors, potentially making crosslinks between proteins.

Footprint areas of pollen from alder (Alnus) and birch (Betula) in the UK (Worcester) and Poland (Wrocław) during 2005–2014

open access: yesActa Agrobotanica, 2015
In this study we analyzed daily pollen concentrations of Alnus spp. and Betula spp. from Worcester, UK and Wrocław, Poland. We analyzed seasonality, annual pollen index and footprint areas for the observed pollen concentrations by using the trajectory ...
