Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages): a review

open access: yesBoreas, EarlyView.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Restoring the lost Ericaceae of Botany Bay's scrublands through a paleoecological approach in southeastern Sydney, Australia

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction With anthropogenic environmental change accelerating, incorporating long‐term perspectives into ecological restoration is essential. Paleoecological evidence increasingly indicates that many perceived “natural” landscapes under current conservation regimes are, in fact, cultural or modern systems.
