Fossil pollen samples suggest vulnerability extinctions ahead
2020/9/4
Reduced resilience of plant biomes in North America could be setting the stage for the kind of mass extinctions not seen since the retreat of glaciers and arrival of humans about 13,000 years ago, cau...
Springtime rains can be a surprising source of pollen, according to research supported by the National Science Foundation.University of Iowa researchers report that tree pollen fragments remain in the...
Scientists discover ancient safety valve linking pollen to bacteria
Scientists ancient safety valve pollen to bacteria
2015/11/12
Like seeds, pollen loses most of its water during maturation, entering a state of suspended animation. This allows it to survive its journey from male to female organs of a flower, where it is rehydra...

Simulating pollen concentrations with numerical
weather prediction (NWP) systems requires a parameterization for pollen emission.
Regulation of the actin cytoskeleton in the pollen tube
Pollen tube ovule sperm plant sexual reproduction actin cytoskeleton protein
2014/12/11
Pollen tube growth, the process that transports the sperm cell to the ovule, is fundamental for plant sexual reproduction. The actin cytoskeleton is essential to the process of pollen tube elongation....
Understanding the Links Between Human Health and Climate Change: Agricultural Productivity and Allergenic Pollen Production of Timothy Grass(Phleum pratense L.) Under Future Predicted Levels of Carbon Dioxide and Ozone
Carbon Dioxide Climate Change Grass Pollen Human Health Ozone Phleum pratense
2014/11/4
The prevalence of allergic disease is expected to increase with climate change. Grasses, which have highly allergenic pollen, are widely distributed across the globe. Changes in production and allerge...
Natural traps of spores and pollen grains from the region surrounding Wenbi Reservoir, Yunnan, China
natural pollen traps Wenbi Reservoir Yunnan China vegetation
2014/1/16
We did a comparative analysis of pollen and spores from five kinds of natural pollen traps at Wenbi Reservoir, northwest Yunnan, China. The natural traps were the surface soil, ground inhabiting mosse...
Pollen-based biome reconstructions for Latin America at 0, 6000 and 18 000 radiocarbon years ago
Latin America Pollen-based biome
2009/12/3
The biomisation method is used to reconstruct Latin American vegetation at 6000±500 and 18 000±1000 radiocarbon years before present (14C yr BP) from pollen data. Tests using modern pollen data from 3...
