“…The author examined the relationship between the flowering of the genera Alnus, Corylus, and Betula and the occurrence of airborne pollen, reporting that pollen grains of species not found in the study area were nonetheless found in pollen rain samples. Green et al (2004) noted that small pollen grains, such as those of the family Myrtaceae, can travel thousands of kilometers from their region of origin and contribute to aerobiological loads at other geographic localities. The authors pointed out that, after any initial deposition, pollen grains can be resuspended by gusts of wind during turbulent climatic events.…”

First records of pollen rain in bromeliad tanks in an area of caatinga in northeastern Brazil

Species of Bromeliaceae have leaves in a spiral configuration. Because of the shape of the rosette thus formed and the imbricate configuration of the leaf sheaths, there is usually a tank in which rainwater and other components of the environment, including pollen grains, accumulate, making such tanks effective pollen rain collectors. The objective of this study was to use bromeliads as a tool to increase knowledge about the vegetation of the caatinga (shrublands) in the Canudos region of the state of Bahia, located in the semi-arid zone of Brazil, as well as to analyze the dynamics of pollen dispersal and deposition. To that end, we collected samples of the water from the tanks of bromeliads at the Canudos Biological Station. A total of 149 pollen types were detected, 88 of which could be identified botanically. The families that were the most well-represented among the pollen types were Fabaceae (with 25), Asteraceae (with 9), and Euphorbiaceae (with 7). Ten pollen types were presented as potential indicators of caatinga vegetation. We conclude that tank bromeliads are useful for gathering information about pollen rain and pollen dynamics, as well as about the transport and deposition of pollen in the caatinga.

“…In Sydney, Cupressaceae pollen makes up 28% of the yearly pollen load, with most of this pollen type probably originating from urban plantings of introduced species. By contrast, in Brisbane, where Cupressaceae pollen is around 9% of the yearly pollen load, Green et al (2004) considered there to be a much greater input from native Callitris species. In Darwin Callitris intratropica is the dominant Cupressaceae species in the landscape, with Callitris pollen comprising round 11% of the yearly pollen load (Table II).…”

“…Therefore the category represents a broad range of ecological habitat, from swamps and riparian zone vegetation to savanna woodland, and the influence of meteorological factors on each of these. Green et al (2004) looked specifically at the relationship between meteorological factors and the pollen seasons of three native arboreal taxa; namely Casuarinaceae, Cupressaceae and Myrtaceae. They separated out these three families from a five-year aeropalynology study for Brisbane and analysed the average monthly loads against meteorological data.…”

“…Callitris intratropica is known to fruit between June and October (Brock, 2001) making the second peak in November a curiosity. Refloating of pollen or long distant transport by inland winds is a possibility (e.g., Green et al, 2004;Stennett & Beggs, 2004) and will be tested with ongoing monitoring and statistical analyses that incorporate meteorological data.…”

Pollen loads in the atmosphere of Darwin, a city located in the wet-dry tropics of Australia, have been monitored for the period March 2004 to November 2005 as part of a large research program looking at atmospheric particles and human health. Seven pollen types dominate the pollen spectrum, the herbaceous families of Poaceae (grasses) and Cyperaceae (sedges), as well as several native tree and shrub taxa, Acacia, Callitris, Casuarina, Arecaceae and Myrtaceae. The pollen loads were found to have a strong seasonal component associated with the alternating wet (November to March) and dry (April to October) seasons of the region. Seventy percent of the yearly pollen load is captured during the dry season, with the peak pollen period occurring at the onset of the dry season (April-May) when most grasses are in flower. The daily pollen concentration decreases as the dry season progresses, accompanied by a change in composition; fewer herbaceous but increasing woody taxa. Preliminary health outcomes reveal a positive association between hay fever, Poaceae and Acacia pollen, as well as a significant association between total fungal spore concentrations and asthma. The Darwin record contrasts significantly with surveys conducted in the subtropical and temperate cities of Australia where temperature as opposed to rainfall and the prevalence of northern hemisphere exotic tree species have a greater influence over the seasonality and composition of the pollen loads.

“…This plant, whose common name is Australian Pine, is native to Africa, Australia, and Southeast Asia. It is wind-pollinated and produces an exceptionally large number of pollen grains (25). Casuarina pollen was found in only a single archaeological sample, which may indicate limited contamination in 1 of 126 samples.…”

For more than 40 y, there has been an active discussion over the presence and economic importance of maize ( Zea mays ) during the Late Archaic period (3000–1800 B.C.) in ancient Peru. The evidence for Late Archaic maize has been limited, leading to the interpretation that it was present but used primarily for ceremonial purposes. Archaeological testing at a number of sites in the Norte Chico region of the north central coast provides a broad range of empirical data on the production, processing, and consumption of maize. New data drawn from coprolites, pollen records, and stone tool residues, combined with 126 radiocarbon dates, demonstrate that maize was widely grown, intensively processed, and constituted a primary component of the diet throughout the period from 3000 to 1800 B.C.
