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.

Landscape-scale drivers of glacial ecosystem change in the montane forests of the eastern Andean flank, Ecuador [PDF]

, 2018
Understanding the impact of landscape-scale disturbance events during the last glacial period is vital in accu- rately reconstructing the ecosystem dynamics of montane environments. Here, a sedimentary succession from the tropical montane cloud forest of

Variabilité des enregistrements polliniques en montagne et reconstitutions paléoécologiques

Belgeo, 2006
Pollen study of five sedimentary sequences cored in the vicinity of Annecy (Lac d’Annecy 450 m, Poisy 490 m, Les Rondets 940 m, Bouttecul 1200 m, Plateau des Glières 1500 m) shows the variability of pollen records in a small geographical area.
