Pollen analysis of Australian honey. [PDF]
PLoS One, 2018 Pollen analysis is widely used to verify the geographic origin of honeys, but has never been employed in Australia. In this study, we analysed the pollen content of 173 unblended honey samples sourced from most of the commercial honey producing regions in southern Australia.

Subfossil pollen spectra as evidence of the altitudinal zonation of the Southern Sikhote-Alin [PDF]
Геосистемы переходных зон, 2022 The correspondence of pollen spectra from surface soil samples from the Olkhovaya Mountain (height 1669 m) to vertical belt vegetation (coniferous-broadleaved forests, spruce-fir forests and golets belt) was analyzed. Attention is paid to the analysis of

Frontiers in Ecology and Evolution, 2022 Projected changes in climate are expected to shift the ranges of many tree species poleward and to higher elevations. Here, we examine past changes in forest composition in Pacific Canada using a paleoecological approach and investigate the role of past ...

Frontiers in Ecology and Evolution, 2022 Our overall understanding of long-term climate dynamics is largely based on proxy data generated from archives such as ice cores, ocean sediments, tree rings, speleothems, and corals, whereas reconstructions of long-term changes in vegetation and ...

Insects, 2022 Ornamental nursery plants are both a major agricultural industry in the U.S. and a major feature of the urban and suburban landscape. Interest in their relationship with pollinators is two-fold: the extent to which they provide a nutritional benefit to ...

Geosciences, 2023 To complement discussions about vegetation history and climate variations in south Greenland, especially during the Norse settlement, we developed a sedimentological multiproxy approach to study a 4300-year-old lacustrine core comprising pollen analysis,

Frontiers in Ecology and Evolution, 2021 Globally, both managed and wild pollination services are unable to meet current rates of crop production and pollination demand. Wild pollination services could be improved through the reforestation of agricultural land margins, however plant–pollinator ...

Identifying Urban Sources as Cause of Elevated Grass Pollen Concentrations using GIS and Remote Sensing [PDF]
, 2013 We examine here the hypothesis that during flowering, the grass pollen concentrations at a specific site reflect the distribution of grass pollen sources within a few kilometres of this site.We perform this analysis on data from a measurement campaign in
