Abstract:

Airborne pollen surveys provide information on various aspects of biodiversity and human health monitoring. Such surveys are typically conducted using the Burkard Multi-Vial Cyclone Sampler, but have to be technically optimized for eDNA barcoding. We here developed and tested a new airborne pollen trap, especially suitable for autonomous eDNA-metabarcoding analyses, called the A1 volumetric air sampler. The trap can sample pollen in 24 different tubes with flexible intervals, allowing it to operate independently in the field for a certain amount of time. We compared the efficiency of the new A

Abstract:

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 other one at rooftop (35 m AGL), 4.2 km apart. In general, 1.4 ± 0.5 times higher pollen amounts were measured by the trap located at ground level, but this effect was less than expected considering the height difference between the traps. Pollen from woody trees such as Alnus, Betula, Corylus, Fraxinus, Picea, Pinus and Quercus showed a good a

Abstract:

The diet of a population of western pygmy possums, Cercartetus concinnus Gould (Marsupialia: Burramyidae), at Innes National Park, South Australia, was examined using faecal and fur pollen swab samples in relation to monthly plant phenological data. Eucalyptus pollen was the most abundant in both faeces and in fur swab samples, followed by Melaleuca pollen; plant exudates could not be examined by this study. Moth scales were found in 26% of the scat samples. Faecal samples comprised most plant species identified (15 of 17), but up to 25% of plant species recorded from fur pollen swabs were not

Abstract:

Abstract Pollen is the source of protein for most bee species, yet the quality and quantity of pollen is variable across landscapes and growing seasons. Understanding the role of landscapes in providing nutritious forage to bees is important for pollinator health, particularly in areas undergoing significant land-use change such as in the Northern Great Plains (NGP) region of the United States where grasslands are being converted to row crops. We investigated how the quality and quantity of pollen collected by honey bees (Apis mellifera L. [Hymenoptera: Apidae]) changed with land use and acros

Abstract:

The use of pollen and spores in environmental studies is primarily in its application to the study of vegetational history and the relevance of atmospheric pollen content to the vegetation of a region is related to the palynomorphs produced in situ and those supplied from the surrounding ecological zones. Aeropalynological studies towards monitoring environmental change in Akoko North-East Local Government Area of Ondo State, Nigeria through pollen analysis was carried out in five randomly selected locations comprising of ten sampling sites to determine the pollen types present in the atmosphe

RESUMEN. Estudio del polen atmosférico y su relación con la vegetación local. La Plata, Argentina. Se analizó el registro de polen en la atmósfera de la ciudad de La Plata (34° 55 ́S, 57° 57 ́W°) y su relación con la vegetación arbórea del área. La toma de muestras polínicas se llevó a cabo con un captador tipo Hirst (Lanzoni VPPS 2000) y se censó la vegetación arbórea de 1km2. El 99% del polen determinado se correspondió con fuentes emisoras locales. El 53% de los taxa no estuvo representado en el registro dado, principalmente por su polinización entomófila. Se registró polen extralocal y, en

Abstract:

Abstract People spend most of their time in indoor environments and, consequently, these environments are more significant for the contribution of the daily pollutant exposure than outdoors. In case of children, a great part of their time is spent at school. Therefore, evaluations of this microenvironment are important to assess their time-weighted exposure to air pollutants. The aim of this study was to assess the children exposure to bioaerosols at schools from two different types of areas, urban and rural. A methodology based upon passive sampling was applied to evaluate fungi, bacteria and

Abstract:

Olea europaea L. pollen is one of the main causes of pollinosis and respiratory diseases in the Iberian Peninsula (IP). The aim of this study was to provide a pollen calendar in different regions of the IP, which could help allergists and allergic patients in the management of Olea europaea allergic diseases, and to update/complement what has already been reported on olive trees’ aeropalynology in this region. Airborne Olea pollen dynamics were analyzed over a period of 8 years in a total of 21 localities, 7 in Portugal and 14 in Spain. Airborne pollen monitoring was carried out using the Hirs

Abstract:

Although nearly 50 years have passed since P.B. Sears introduced pollen analysis to North America, it remains an occult art. Dramatic improvements in sampling and analytic techniques continue to be limited by intractable problems of differential production, dispersal, ballistics, sedimentation, and preservation. It is a basic tenet of pollen stratigraphy that the data set, consisting primarily of microfossils preserved in sediments, is better than anything we have yet been able to do with it. Basic agreement between late- and postglacial pollen records has been confirmed wherever the method ha

The London plane tree is frequently used in gardens, parks, and avenues in European urban areas for ornamental purposes with the aim to provide shade, and given its tolerance to atmospheric pollution. Nevertheless, unfortunately, over recent decades, bioaerosols such as Platanus pollen grains cause increasing human health problems such as allergies or respiratory tract infections. An aerobiological sampling of airborne Platanus pollen and Pla a 1 allergen was performed using two volumetric traps placed on the roof of the Science Faculty building of the city of Ourense from 2009 to 2020.

Abstract:

Oak pollen has great potential to be used in reconstructing paleovegetation and paleoclimate. Pollen grains from Holocene sediments of Rolla, Missouri, USA were studied. The goal of this study was to evaluate the morphology of dispersed oak pollen using light and electron microscopy. Three types of oak pollen were recognized: Group 1, Group 2, and Group 3. They occurred in the sample in the following approximate percentage: 52, 32 and 16% respectively. Pollen of Group 1 corresponds to that of white oaks, pollen of Group 2 to that of red oaks. Pollen of Group 3 differs from oak pollen known for
