“…Thus, changes in the amount of registered pollen have been used in studying changes in vegetation (Pidek 2007 ;Kobzar 1999 ) and in environmental conditions (e.g. Damialis et al 2007 ) , which could be of particular interest for forecasts. However, the pollen index can be a biased measure of the reproductive output of the plants, as it is in fl uenced by factors such as the atmospheric transport and deposition of pollen, and weather factors affecting the emission process (Ranta et al 2008 ) .…”

The onset, duration and intensity of the period when pollen is present in the air varies from year to year. Amongst other things, there is an effect upon the quality of life of allergy sufferers. The production and emission of pollens are governed by interacting environmental factors. Any change in these factors may affect the phenology and intensity of the season. Readiness to fl ower in a plant, and the amount of pollen produced, is the result of conditions during an often long period foregoing fl owering. When a plant is ready to fl ower, temporary ambient circumstances e.g., irradiation and humidity, determine the timing of the actual

“…Furthermore, in some areas, pollen and spore concentrations have been found to be positively associated with mean air temperature [186][187][188]. However, the pattern of change is highly heterogeneous by species, season, and geography [187,[189][190][191]. In northern Italy, an increase in the overall incidence of asthma has been observed [192].…”

Abstract:The evidence of observed health effects as well as projections of future health risks from climate variability and climate change is growing. This article summarizes new knowledge on these health risks generated since the IPCC fourth assessment report (AR4) was published in 2007, with a specific focus on the 53 countries comprising the WHO European Region. Many studies on the effects of weather, climate variability, and climate change on health in the European Region have been published since 2007, increasing the level of certainty with regard to already known health threats. Exposures to temperature extremes, floods, storms, and wildfires have effects on cardiovascular and respiratory health. Climate-and weather-related health risks from worsening food and water safety and security, poor air quality, and ultraviolet radiation exposure as well as increasing allergic diseases, vector-and rodent-borne diseases, and other climate-sensitive health outcomes also warrant attention and policy action to protect human health.

Airborne freshwater and marine microeukaryotes in the city of Thessaloniki, situated in Thermaikos Bay, Greece, were examined as sources of colonization of experimental water containers during the period autumn 2007 to spring 2008. The microeukaryote composition of the plankton in the nearby aquatic systems (distance <1 km) was also examined. Airborne microeukaryotes were examined by morphology and 18S rRNA gene diversity. A total of 29 species of airborne microeukaryotes were identified, most of them commonly observed in aerobiological studies. Airborne organisms of only 8 taxa were also detected in the nearby aquatic systems. The algae Haematococcus lacustris, a Chlorella-like taxon, and Scenedesmus cf. obliquus, the heterotrophic nanoflagellates (HNF) Bodo sp., Cafeteria minuta and Rynchomonas nasuta, and the ciliate Pattersoniella vitiphila were present in all 3 seasons, indicating capabilities of successful dispersal and colonization under a wide range of meteorological conditions. Rapid colonization of the water containers by the microeukaryotes occurred at the beginning of the experiment, but the rate of colonization quickly stabilized. The initial phase of colonization was dominated by HNF; subsequently, members of the Chlorophyta were the dominant autotrophs. The heterotrophic and autotrophic colonists established similar food webs in all 3 seasons, with P. vitiphila being the common top predator.

It also seems that the observed biogeography of aquatic microeukaryotes is influenced by the method of study: species identified solely by morphology seem to be widely distributed, but whether such species come from the same genetic populations remains debatable (Dolan 2005). Thus, there is a demand for combining information on the distribution of microeukaryotes based on morphology and phylogeny with information on life cycles and colonization potential in order to unravel biogeographical trends.The majority of airborne algae belong to the Chlorophyta (Schlichting 1964, Lopez-Bautista et al. 2007, see also review by Sharma et al. 2007). This group of autotrophs forms the bulk of the community of aeroalgae in most biogeographic regions, as proposed by Roy-Ocotla & Carrera (1993). Even deserts are found to be hotspots for chlorophyte biodiversity (Lewis & Lewis 2005). The few available studies that focus on airborne protozoa from different habitats and regions reveal some common taxa in their lists (Schlichting 1964, Schlichting 1969, Smith 1973, Rivera et al. 1992, Rogerson & Detwiler 1999) but they do not provide insight on the fate and the interactions of these airborne microorganisms.
