Parietaria judaica (Urticaceae) grows abundantly in urban areas of the Mediterranean region. Its pollen is a major allergy source. We studied the species’ distribution and abundance in and around Thessaloniki (Greece), pollen production and pollen season. We also examined how urban pollution affects pollen viability. Our ultimate goal was to obtain an estimate of the species’ performance and ability to expand under different environmental conditions related to climate change. We mapped P… 

Temporal patterns of pollen shedding for longleaf pine (Pinus palustris) at the Escambia Experimental Forest in Alabama, USA

Longleaf pine is an important tree species in the southeastern United States and studying the temporal patterns of pollen shedding is crucial to a better understanding of its phenology and seed

Microsatellite primers in Parietaria judaica (Urticaceae) to assess genetic diversity and structure in urban landscapes1

The microsatellite primers characterized for Parietaria judaica will be useful for examining genetic diversity and population genetic structure in this urban plant.

Climatic change in Mediterranean area and pollen monitoring

The weather conditions directly influence pollination by determining time of onset of flowering, the number of pollen grains produced, and by controlling the amount of pollen that is discharged into

The Influence of Urban Conditions on the Phenology of Aesculus hippocastanum L. Using the Example of Wroclaw (Poland)

The differences in plant phenology between rural and urban areas are the subject of research conducted all over the world. There are few studies aimed at assessing the impact of the urban heat island

The duration and severity of the allergenic pollen season in Istanbul, and the role of meteorological factors

Information on the allergenic pollen season provides insight on the state of the environment of a region and facilitates allergy symptom management. We present a retrospective analysis of the

The relation of spring pollen release to weather in Fairbanks, Alaska

Twenty-three years of pollen data for Fairbanks have been analyzed and related to meteorological data (temperature, wind, relative humidity and precipitation). The purpose of this research is to



Phenology and pollen production of Parietaria judaica L. in Catalonia (NE Spain)

Variability of phenology and pollen production of three geographically distant (20–60 km) populations of Parietaria judaica L. in Catalonia (Spain) was analysed together with their relationships to

Pollen viability as a bio-indicator of air quality

The statistical analysis (ANOVA) showed that the main source of variability of the pollen viability depends on the plant but also the site and the interaction between plant and site were very important with a high significant level (p < 0.0001).

Interaction of the Onset of Spring and Elevated Atmospheric CO2 on Ragweed (Ambrosia artemisiifolia L.) Pollen Production

Ragweed pollen production can be expected to increase significantly under predicted future climate conditions, and timing and CO2 interacted to influence pollen production.

Pollen Viability for Air Pollution Bio-Monitoring

Biological characterization of Corylus avellana L. and Pinus nigra L. pollen samples was carried out to determine the actual value of pollen as a bio-indicator of the effects of atmospheric

Pollen production in the Poaceae family

Total pollen production per inflorescence was studied in the most important species of the Poaceae family in the city of Córdoba in order to further our knowledge of the partial contribution of each


Variation in pollen production was measured within five hermaphrodite species of bromegrass (Bromus). Anther length is an excellent predictor of pollen production in this genus (R2 = 0.97). Anther

The sensitivity of pollen from various coniferous and broad-leaved trees to combinations of acidity and trace metals

The pollen of Populus tremuloides L. Tremuloides was shown to be highly sensitive to pH, and a synergism between pH and copper on pollen function in this species was demonstrated, in contrast to the general antagonistic interaction of pH and Copper noted in the other species tested.

Histochemical properties and trace element concentrations in Parietaria L.from urban sites (Palermo, Italy)

We examined leaf and pollen histochemical properties in Parietaria L. and measured trace element concentrations in urban sites in Palermo, Sicily, affected by different stress valence levels. Urban

[Sensitization to Castanea sativa pollen and pollinosis in northern Extremadura (Spain)].

The atmospheric fluctuations and prevalence of patients sensitized to Castanea pollen in the authors' region and to compare this sensitization with sensitizations to other pollens were analyzed to determine the most important allergenic pollens in northern Extremadura.
